This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "uClibc-ng - small C library for embedded systems". The annotated tag, v1.0.1 has been created at 98b794026f64edf68721ffb5fe640107e2bd3cc0 (tag) tagging 3b8d53ecf756a2352227b6c12eefb63847318005 (commit) tagged by Waldemar Brodkorb on Sun Mar 8 21:37:27 2015 +0100 - Log ----------------------------------------------------------------- release 1.0.1 (codename pauwel kwak) "Jan-Benedict Glaw" (6): Allow for targets that don't know about signed zero floats. Really define, not undefine the crash statement... The VAX gas cannot (yet) cope with the tricks played here, so I'm grounding linktime warnings for now. First round of VAX patches. This isn't complete right now, there are for sure still bugs (properly hidden, of course), a libm is completely missing (I've got one that implements some basic stuff, but that's really not ready for checking in...) TODOs for the VAX port. Assebler sources ment to be preprocessed shouldn't contain assembler comments, but C comments instead... "Steven J. Hill" (126): Fixed MIPS dynamic linker by removing link order dependency bug. Changes needed for MIPS with regards to the .init and .fini sections. Added more debug code. Changed path where cross development tools are installed. Moved to 'sys' directory. Changes so that 'regdef.h' gets included in the development environment. If we are cross-compiling, don't even try to build the target utilities. Fix up of '_dlopen' call and removal of unneeded argument in call '_dl_load_elf_shared_library'. Change default config files for MIPS platforms. Nothing major. This rule is only necessary for little endian MIPS. Remove source files that, well, no longer exist :). ldso specific syscalls and userspace syscalls all in one file now. Addition to 'distclean' for little endian MIPS. Ignore symbol '_gp_disp' if it's missing from 'libgcc.a'. That's okay for MIPS platforms. Added function 'get_current_dir_name' for Linux Test Project. Tested and works identically to function in glibc. Added function 'mkdtemp' for Linux Test Project. Add syscalls: modify_ldt _sysctl setresuid getresuid setresgid getresgid Added 'valloc' back in. Ok, Erik can smack me now. Per discussions with Erik, 'valloc.c' should be built on top of whichever memory allocator you choose. Unfortunately, the 'malloc-930716' needs a fair amount of work before it is functional. For now, changes have been made to add the 'valloc' call and it works properly with the plain 'malloc' allocator. Fixed 'struct ipc_perm' and 'struct msqid_ds' members to allow the Linux Test Project to compile as well as be consistent with the architecture specific files. Maybe eventually the architecture specific files could be removed all together. 'syscall' now properly works for MIPS. Fixed compile bugs having to do with 64-bit filesystem operations that need to be disabled when 'DOLFS' is disabled. Don't unconditionally save/restore FP registers, we might be doing soft floating point. Thanks to Jay Carlson. Forgot one more #ifdef related to MIPS soft floating point. Implemented 'romfs' target so that uClibc works with building uClinux. Fixed 'dlopen' call for MIPS. Things seem to work swimingly. Woohoo! Fixed makefiles to remove binaries generated for the configuration menu system when doing a 'make clean'. Fix target determination for MIPSEL. Changes for MIPS and new configuration system. Add in 'ldso' to directory list since 'make clean' was not recursing into it. Changed '__kernel_nlink_t' data type to match Linux/MIPS kernel type definition and to be consistent with the ABI. Done per conversation with Ralf (Linux/MIPS) maintainer. Compliance with MIPS ABI and MIPS kernel changes. GCC-4.1.0 doesn't like it when you reference 'extern' one place and then try and declare the variable static in another. Let's not do that. Get rid of extern references to ldso variables. Add in configuration item and Makefile changes for NPTL. We will be placing the NPTL code under the top-level 'libpthread' directory. Nothing compiles or even works at this point, so do not enable this option. Haha. I caught it before you did. Import in NPTL code from glibc. For further information please consult the 'README.NPTL' file. Remove additional test programs. Remove extraneous file. We already have these defined. Cleanup original linuxthreads and update top-level threads makefiles. Backwards compatability? Bhuwhahaha....you wonder why glibc is so bloated. *oink* *oink* More glibc backward compatibility cruft. Oh the horror! Put the change log back in. Remove usage of 'hp-timing.h' header file which is for platforms with high performance timers. If you want them included in the NPTL build, copy the header from glibc into the 'libc/sysdeps/linux/<ARCH>' of your choice and have fun. Added new common include file for list primitives used by NPTL. Added new 'bits/atomic.h' for most of the architectures and the top-level 'include/atomic.h' to add in new atomic operations for use by NPTL. There are multiple files for PowerPC and Sparc for 'atomic.h'. I will let those architecture maintainers choose the correct file. The files come from glibc in 'sysdeps/ARCH/bits'. Top-level makefile fix for OS agnosticism and set the value of TARGET_ARCH using grep because the '.config' will not get included if we are doing a 'clean' or other targets. This was preventing the proper cleaning up target architecture include files. Add missing file to the clean list. In order to accomodate usage of either pthreads implementation, we now have to create symbolic links for 'semaphore.h' and 'pthread.h' which will point to the proper pthreads directory. When we finish getting NPTL working with uClibc, perhaps we can merge them, but a first glance at the differences between the two does not make that very likely. Add TOPDIR prefix in front of config file when getting target architecture. Sync uClibc 'sigthread.h' with the latest version from glibc. There were two versions of 'pthreadtypes.h' originally in uClibc. Also, since we are going to support the two implementations of pthreads, we again need to instead create symbolic links to use the proper version of the file depending on the pthreads option chosen. Get rid of crud. Fix up some more NPTL stuff for header file symbolic links. The function '_dl_memset' should always be inlined regardless of the optimization level chosen. This allows uClibc to be compiled with the latest GCC-4.1.0. While tracking down the specific culprit causing the segmentation fault of the dynamic loader with GCC-4.1.0 I was able to force inlining of other functions such that I shaved 512 bytes off the size of the loader, yay. Also fixed warning in 'dl-hash.c'. Remove unused include directory. The newly added __glibc_strerror_r function is probably fine, but the uClibc did not even compile or link without errors. This fixes that up. Please test more thoroughly next time. 'pthread.h' is not the only file that needs to be symlinked. When NPTL gets merged, you will need to do 'semaphore.h' and 'bits/pthreadtypes.h'. I think I have been a good little boy and keeping my NPTL changes out of mainline, so I'm going to go ahead and cross the line this once to get this change in. 'pthread.h' is not the only file that needs to be symlinked. When NPTL gets merged, you will need to do 'semaphore.h' and 'bits/pthreadtypes.h'. I think I have been a good little boy and keeping my NPTL changes out of mainline, so I'm going to go ahead and cross the line this once to get this change in. I really really HATE gcc-4.1 and its whimsical inline rules. Remove unneeded if clause. We won't be in this directory unless we have enabled threads. Change the order in which '__uClibc_init' is called. In the case of NPTL, some auxillary TLS set up has to happen beforehand. This has been tested for almost two months now and I am tired of chasing it around in my merges. Look in the NPTL trunk if you want more information. Clean up debugging levels for MIPS. This should make things consistent now. Again, I need to cut down on my merge times and this last set of changes to the makefile structure is killing me. Sorry to put more native thread stuff in, but it cannot be activated in the trunk, so there is no harm. Neaten up the libpthread directory. Clean up pthread include mess. Some of these will be needed to support NPTL, but they do no harm for the linuxthreads case. Yes, I tested this. One more addition. Fix broken path for PTDIR which needed a '/' at the end to work. Also brought in the other stuff needed for NPTL. Erik, please cut me some slack again. The option is not in 'extra/Config/Config.in' so it cannot be activated. Besides, take a look at the check in tonight on the branch and the post on the mailing list. Need to get both .o and .os files. (.os files are built for NPTL) Oops, that was a bad wildcard. Fix up PTDIR bug and clean target for libpthread. Do not set the RELOCS_DONE flag until it is actually done. This order matters for NPTL libpthreads to work. Well, that was a nice waste of 3 hours. Tab clean-up. You included the wrong file. Check your work better next time. You get a big fat "F" for this one. Add needed include to build loader. Fix make macro. Did you even fricking test this? Enable alias for 'bcopy' otherwise BusyBox will not build *sigh*. No, '__mempcpy' is used by user-space applications, like coreutils for example and glibc still has '__mempcpy' as a global symbol. How about this, do a complete buildroot file system after hacking uClibc to make sure things work? There's a novel idea. Fix includes for NPTL thread model. Move 'librt' includes to be after pthreads since NPTL will be also be adding new code for this library. Be afraid, be very afraid. Part deux. We need these aliases to stay so that NPTL can override them. Get rid of compiler warning. Yeah, suck it up. I'm tired of merging stuff. Merge from NPTL. Remove unused weak_alias. Thanks Peter. The minimum is different for NPTL because of two new signals. Merge from NPTL branch. Merge from NPTL branch. Bring in the remaining changes for sigaction. Fix alias. Merge from NPTL branch. Fix debugging. Merge from branch. Merge from branch and add removal of 'tls.h' when using NPTL threads. Merge from NPTL branch. Merge from NPTL branch. Merge from NPTL branch. Congratulations! You get the stupid award for not including <signal.h> to pull in the signal #define's. How did this compile for you again? Apply patch from Joseph Myers for MIPS pipe and get rid of the C version. Patch tested. Sloppy patching on my part. This should be correct. Use the TSD macros and get rid of warnings. This never gets defined. I have a patch pending in glibc too. Revert change. Calls can only be used when utilizing TLS. Sorry for the breakage. Remove commented include. I'm seeing double. Whitespace and tab cleaning. Do NOT hide 'utime'. When building binutils for the target using buildroot it was undefined. How about when you finish playing hide and seek with symbols you do a complete buildroot build and see if everything really works. $!#@$!#@ If locale support is not enabled, don't build 'tst_ftime_l'. Fix tests to work if MALLOC_GLIBC_COMPAT is enabled. Fix 'realloc' and revert previous changes to tests. malloc tests all pass regardless of the setting of MALLOC_GLIBC_COMPAT. Revert change to remove 'error_print_progname' so that gettext will build. It can be commented out again when someone figures out how to fix gettext building and do the proper thing. Update ARM EABI kernel interface due to layout and size of struct stat64. Remove SA_ONSTACK handling for ARM based up on glibc code as submitted by Paul Brook <paul(a)codesourcery.com>. Add CHECK_ONLY option to allow for running the tests on the target instead of attempting to link or compile them. Perhaps I don't fully understand the test structure, but for TLS and NPTL the tests cannot be compiled on the target without a full source tree. Remove definition of TIMER_MAX which breaks builds of GCC-4.2 and in glibc code it is not defined. <none> The case for _SC_MONOTONIC_CLOCK should only exist if 'clock_getres' does. Disable declarations for NPTL. This test needs XLOCALE to work. Fix ARM EABI signal unwinding to accomodate signal frame layout between Linux kernel versions as reported by Joseph S. Myers on the mailing list. More information available at <http://www.uclibc.org/lists/uclibc/2007-May/017971.html> . Fix MIPS syscall() and pipe functions to set errno correctly as reported by Daniel Jacobowitz on the mailing list. More information available at <http://www.uclibc.org/lists/uclibc/2007-May/017968.html> . Fix broken syscall() function since the original patch did not work. Apply patch as submitted by Blue Smurfy Swirly <blauwirbel(a)gmail.com> for Sparc32. Enable all of the remaining baud rates. All of the other architectures have them enabled, so let's go all the way. There was a quick discussion on IRC about making the max baud rate configurable. That requires a bunch of #ifdef salting throughout all of the 'termios.h' files for the pre-processor to chew on. I'm going to pass on that for now. Filter out '-std=gnu99' when running the assembler.

Certain configure scripts test for presence of dlfcn.h. Don't install it if !HAVE_SHARED. sys/procfs.h defines a typedef for floating point registers that references an undefined structure. This typedef is used in linuxthreads.old-db, causing a compilation failure. Fixed by defining an empty structure for it - we don't have fp regs anyway. Add Blackfin specific mmap implementation using sys_mmap2. Ignore entries of "-1" in rofixup; the linker sometimes has no choice but to create these for deleted entries in .eh_frame. Change test for a define that got renamed a while ago. From Jie Zhang: __bswap_16 could not assume that it's zero extended when an unsigned short int is loaded into the data register. mcontext_t shouldn't have a version argument, and fix REG_B0 definition. A better atomic ops implementation for the Blackfin, relying on a feature present in our recent kernels. Add necessary Makefile rules for the Blackfin. Some shared flat improvements. Fix minor errors: - UCLIBC_SHARED_FLAT_ID instead of SHARED_FLAT_ID - use -Wl,-shared-lib-id properly Use libc_so.a as the source for the shared libc, in order to be able to use -mleaf-id-shared-library on the Blackfin. Add some necessary Makefile bits for UCLIBC_FORMAT_FLAT_SEP_DATA. Blackfin crt1.S fixes for building with -msep-data. Fix merging error: a macro was renamed. Blackfin FD-PIC patch 1/6. Add a new function _dl_free. In _dl_malloc, ensure we always get back a full page from mmap. Reset _dl_malloc_function and _dl_free_function when libdl is initialized. Blackfin FD-PIC patch 2/6. Add the necessary changes in ld.so and libdl to deal with targets that prepend an underscore to symbol names. Blackfin FD-PIC patch 3/6. Change _dl_find_hash to _dl_lookup_hash, as on the NPTL branch. _dl_find_hash is now a wrapper function around it; unlike on the NPTL branch, it retains the old interface so that not all callers need to be changed. Blackfin FD-PIC patch 4/6. Add a hash table for function descriptors on FD-PIC targets. Blackfin FD-PIC patches 5/6. A couple more target macros for ld.so to deal with FD-PIC support. We need special code to compute the initial got and dpnt, and we need to pass extra arguments to _dl_get_ready_to_run. Fix a few warnings introduced by my previous commits. Blackfin FD-PIC patch 6/6. These are mostly the changes necessary to deal with loading the libraries into memory. A couple new target macros are defined for this purpose, and the code in dl-elf.c is modified to deal with nommu systems. Some more Blackfin/FDPIC ldso merging work. Include dl-inlines.h when it exists, and move some definitions to their proper place. A patch from our Blackfin repository, originally from Jie Zhang. This fixes a problem where the linker was trying to use the wrong symbol name for the init function. Another piece needed for FD-PIC. This compiles another startfile, crtreloc.o, if necessary. A patch from our Blackfin repository, originally from Mike Frysinger. Add sysdeps/linux/$(TARGET_ARCH) to the list of includes. Needed by some of the Blackfin specific string assembly files. Update dl-inlines.h from Blackfin repository. L1 memory support for the Blackfin. A couple new syscalls to manage L1 allocations, dma_memcpy to move stuff between L1 and main memory, and a new structure to describe the global data in L1 scratchpad memory. Fix the recent dladdr changes so that they compile on FD-PIC targets. Use DL_RELOC_ADDR when dealing with DL_LOADADDR_TYPE types. Fixes gnu-hash compilation on Blackfin. Fix a dependency to mention libc.so, not libc.so.0, as we only have a rule to build the former. Use $(<D) rather than $(^D), as the latter now contains an element corresponding to FORCE, which causes some CFLAGS to be lost. A slight improvement over my previous commit which ensured we always rebuild libc when one of the source files changes. Still forgot some libraries in one of the previous commits. Fix merge error: mmap.c no longer exists in bfin/. This fixes a problem with the move of libc_hidden_proto to string.h. Undefining __UCLIBC_HAS_OBSOLETE_SYSV_SIGNAL__ did not work, since we were still defining signal to sysv_signal. Fix typo that prevented "make clean" from removing objects in libc/misc/locale. Revert revision 22027 which totally broke getopt. In string.h, move libc_hidden_proto next to the corresponding declaration. Filter them out when installing headers. Revert revision 19342, plus one whitespace fix demanded by the pre-commit hook. Revert revison 19346, except parts needed by later patches (r19347 also added __uc_malloc calls in getnetent.c, so we must retain the include and libc_hidden_proto). Fix two more cases where a libc_hidden_proto was added to string.h while no libc_hidden_def exists for the function. Revert revision 19343 and also remove libc_hidden_proto for __uc_malloc. For now, a straight revert; we can decide later wheter we want to do something more. Revert revision 19344 plus the libc_hidden_proto for __uc_malloc. Revert revision 19345 plus libc_hidden_proto for __uc_malloc. Revert revision 19347, plus libc_hidden_proto for __uc_malloc. Some of the code is functionally identical before and after, but for now I'm just mechanically reverting the entire mess. Allow ABIs where SP points below the stack frame. Implement ffsl and ffsll. Add C6X-specific sys/ptrace.h Add a missing macro to C6X syscalls.h. Select ARCH_HAS_NO_MMU for C6X. Fix nommu handling of DT_TEXTREL Fix malloc alignment Support dynamic assignment of DSBT_INDEX Add a C6X-specific ipc.h. Remove use of attribute_shared_hidden Remove pragma weak for undeclared symbol Accept either __NR__lseek or __NR_lseek Bernd Schmidt bernds_cb1(a)t-online.de (1): Add Makefile support for DSBT ELF. Bernhard Reutner-Fischer (906): - typo in documentation - fixup after sync with glibc. _ptyname was renamed to __libc_ptyname - fix typo in comment. - __td_debug is only needed if NDEBUG is not defined. - use keywords __asm__ and __inline__ c99. - make sure that icc generates bits/sysnum.h pgcc would need a completely different treatment here. - only link asm-generic if it exists. PS: test for existence on Slowaris was disfunctional, last time i looked. Shouldn't matter much here, though.. - fix typo - gcvt() is marked LEGACY in XSI and mandatory in BSD. Also make compilation conditional on float support. - Cleanout the only occurance of the SUSv3 LEGACY function getwd() that was furthermore ifdef'ed out anyway. - honor __UCLIBC_HAS_LFS__ - introduce UCLIBC_SUSV3_LEGACY_MACROS to be able to do away with all LEGACY stuff, even the fallback defines. - fix compilation of __LDSO_CACHE_SUPPORT__ s/dprintf(2/fprintf(stderr/g - provide a hidden_def for fputc_unlocked that is aliased to __fputc_unlocked. Fixes undefined references to __fputc_unlocked when calling fputc(). - r16732 forgot to checkin the sync of the __UCLIBC_SUSV3_LEGACY_MACROS__ from string.h - s/Attemt/Attempt/ - Trim superfluous trailing whitespace. No obj-code changes. - repair misplaced #endif that got introduced in r17410. Fixes compilation. - fix format of comment - commentary typo fix - sync with glibc (and provide a check for icc). Only affects gcc <2.7 or non-gcc compilers that bailed earlier due to missing int64_t - see if defined foo before trying to look at the value of foo (that should be 0 in this case. Avoids some warnings). - s/if USE___THREAD/if defined USE___THREAD && USE___THREAD/g - fix compilation of GNU glob with !LFS Sounds like a typo, really - should look if LFS is enabled as suggested by pkj in #1131. This generates identical cc1 input for LFS enabled (compared to before r17652) but makes sure that we pickup the non-LFS if LFS is turned off (like r17652 did in this case). - silence warning about using an undefined token - silence warning about using an undefined token - kbuild update broke uClibc's configuration. It complains about include/bits/uClibc_config.h since there is no include/bits (yet). Depend on it. - add arm1176 options - dtrt - doesn't make sense to impose a limit that is too narrow. 12 ought to be fine.. - shrink resolver code - include stdbool.h - commentary typo fix - make sure to define _LIBC in libc-symbols.h before including anything else. - internal_function is only used inside libc, so do not define it in uClibc_arch_features.h on i386 if we are outside of libc. - spelling fix - Fix compilation for mips ABI64 with no LFS. This wants a stub_enosys(readahead) line later on, like many, many others need.. - Fix compilation for mips ABI64 with no LFS. - allow for passing in UCLIBC_EXTRA_LDFLAGS - use the compiler-driver instead of the linker - adjust setting flags accordingly to use (hardcoded, see below) -Wl, Potential improvements: *) --warn-unresolved-symbols should perhaps be used for all libs *) eventually rename LDFLAGS to CC_LDFLAGS *) probe for compiler driver's notion of flag to use for passing in linker flags (i.e. don't hardcode "-Wl,") - move UCLIBC_EXTRA_LDFLAGS below pinning LDFLAGS - commentary typo fix - fix order of link-flags On cygwin one has to pass make menuconfig HOST_LOADLIBES="-lcurses -lintl" otherwise just curses is linked in and some symbols that live in intl are unresolved. Closes #1554 and possibly a couple of other reports. - fix whitespace - fixup gnu_inline vs. C99 inline - add missing header guards while at it - Fix compilation: semtimedop has 4 args (and not 6) - check for -nostdlib bits/sysnum.h needs a cross compiler to be built. Fortunately, this header is not needed to build gcc. Move generation of this header. (Yann E. MORIN) - remove unused file - use libm_DIR and libm_OUT - fix linking. We use the compiler-driver and not ld. - fix compilation: In file included from toolchain_build_i386/gcc-3.4.6/libiberty/hashtab.c:49: build_i386/staging_dir/i386-linux-uclibc/sys-include/malloc.h:193: error: ISO C forbids data definition with no type or storage class - add C99 floating point environment, rounding and exception handling functions for i386. UCLIBC_HAS_FENV - wrap superlong lines - forgot to add include/fenv.h - fix file permissions Paul Brook writes: The attached patch adds support for compiling arm uClibc as pure Thumb code. This is needed because some recent ARM codes do not implement traditional ARM mode. Specifically: - fix (parallel) compilation error in ldso.c We have to generate sysnum.h to satisfy all includes of ldso.c - fix generation of sysnum.h for parallel builds, second take. Revert r21503 and redo more cleanly. - improve building utils Either by first compiling objects and linking those or by just passing the source to create the desired binary (this patchlet does the latter). Fixes cosmetic glitch by just not building individual .o (in pwd, at least). - fixup stripping of host utils and make host-utils compile with std=gnu99 - trim trailing whitespace. No object-code changes. - use a 16bit value for fnstsw as required by newer binutils. - fixup asm. No object-code changes - add vmsplice, splice, tee (Timo Teräs) - pull bits/fcntl.h from glibc (Timo Teräs) - indent - implement splice,vmsplice,tee for all arches - synch F_LINUX_SPECIFIC_BASE related fcntls for all arches - cleanup by manually expanding the helpers. Saves several 100 bytes - add missing #endif - silence warning - make it compile with !__UCLIBC_HAS_LOCALE__ - avoid warning due to undefined preprocessor token - avoid warning due to undefined preprocessor token - remove old-style definitions. No object-code changes. - note that __drand48_iterate should be void - do not delete the libs i keep for size-comparison Explicitely list the directories in which we rm the static(only?) libs. - fix warning about static not being at the beginning of a decl - fix warning about old-style function definition This could need a pull from upstream to do away with these __STDC__ conditionals. - my manpage sais that init_module, create_module, query_module, delete_module were removed in linux-2.6 - Wrap overlong comment-lines. No object-code changes - rename to match the setdomainname filename - rename to match the set*() function's filename - fix compilation error - for non-threaded, non-macro case we were missing __GI_fputc (for e.g. error.c) - avoid warning about cast from pointer to integer of different size - use -print-file-name - pull commentary fixes from upstream - fix dependencies for multi-source - shrink a little bit. text data bss dec hex filename 1176 16 24 1216 4c0 libc/misc/syslog/syslog.o.orig 1140 16 21 1177 499 libc/misc/syslog/syslog.o - pull wur settings from upstream. No other changes. - Avoid warning about undefined preprocessor token. No obj-code changes. - Avoid warning about missing brace. No obj-code changes. - Avoid warning about undefined preprocessor token. No obj-code changes. - Avoid warning about missing brace. - fix dependencies of ldso.c Previously a touch ldso/ldso/dl-debug.c && make ldso/ldso/ldso.oS did nothing - Avoid warning about missing brace. No obj-code changes. - nlist is unsigned. Adjust iterator variables accordingly to avoid signedness warnings. - fix the macros rather than the callees as rightfully noted by bernds (duh!) - try to pickup UINTMAX_MAX - Avoid warning about undefined preprocessor token. No obj-code changes. - Fix gcc glitch with mremap and IMA. For -combine, make sure that we don't pollute our non-varargs mremap decl with some vararg decl from later in the TU by putting ours after anybody else who is picking up mman.h. This is admittedly a small work-around.. - cannot really guarantee proper order, so play safe and compile the problematic sources separately for now. - default kernel-modules funcs to on. - fix prerequisites of sysnum.h (has to depend on the script that generates it) - fix whitespace - generate deps via gcc Oh, and prepend a dot to the basename so i don't have to change my habit of calling 'size thefile.o*' - rm all deps on distclean - store the used compiler plus flags in the .%.dep files too and use this info to decide whether or not to rebuild something (if e.g. the filestamp of the prereq did not change but the cc or CFLAGS did). - since we force make into trying to rebuild unconditionally, we have to check for changed prerequisites manually. - breakup lines of compile.c and add a variable to hold filter-out PHONY target. No functional changes. - adds several config-options to allow for turning off certain features like o UCLIBC_HAS_GNU_ERROR o UCLIBC_HAS_BSD_ERR o UCLIBC_HAS_PTY o UCLIBC_HAS_GETPT (1) o UCLIBC_SYSCALL_STUBS o UCLIBC_SYSCALL_STUB_WARNING o UCLIBC_LINUX_SPECIFIC (2) o UCLIBC_BSD_SPECIFIC (3) o UCLIBC_NTP_LEGACY (4) o UCLIBC_SV4_DEPRECATED (5) o UCLIBC_HAVE_REALTIME (6) o UCLIBC_HAVE_ADVANCED_REALTIME (7) o UCLIBC_HAVE_EPOLL (8) o UCLIBC_HAVE_XATTR (9) o UCLIBC_HAVE_PROFILING (10) - Generate dummy rules for prerequisites. Fixes build-failures in ldso when switching thread-impl because of missing rule to make e.g. pthreadtypes.h Thanks to Peter Kjellerstedt for the reminder. - add libpthread-nonshared-y to files.dep Fixes superfluous rebuild of pthread_atfork.oS. - Revert _dl_exit touch-up. It breaks on arches that don't define proper/complete/nice syscall facilities. - fix typo (have to check the content, not if true) - strip the targets and not prerequisites - tidy up PTHREADS_DEBUG_SUPPORT by using per-target STRIP_FLAGS for the few - remove duplicate removing of ustat.h - linuxthreads and linuxthreads.old need nanosleep() - fix keyword "depends on" - pull kconfig from 2.6.25.4 It has nicer "-*-" etc hints - drats. The pre-commit hook is broken. No chance to ci a patch other than obfuscated, sorry. - do a defconfig for the given arch, not unconditionally for alpha - switching thread impls without makeing clean before left the objs of the previously selected impl lying around on a distclean. Make sure that this does not happen. - make libcrypt optional. Untested. - revert r22233 - forgot to checkin this s/check/FORCE/ - UCLIBC_HAS_GETPT pulls in getpt. - ptsname_r depends on UCLIBC_HAS_PTY just like ptsname() - remove __USE_BSD guard from __bsd_getpt(). Fixes compilation error for defined UCLIBC_HAS_PTY && !defined UNIX98PTY_ONLY which need both __libc_ptyname1 and __libc_ptyname2 for ptsname_r(). - revert incorrect parts of r22257 and 22259 since posix_openpt lives in getpt.c it has to stay there unconditionally. - if UNIX98PTY_ONLY is not set then we're in legacy land anyway which needs UCLIBC_HAS_GETPT unconditionally for __libc_ptyname{1,2}[] and related bloat. - Improve prerequisites and avoid spurious reconfigurations. More details: http://uclibc.org/lists/uclibc/2008-June/019509.html - no need to export the included dependencies generated by cc - disregard any and all $(top_builddir) in deps. Fixes e.g. make -C ldso rebuilding unneeded stuff - fix build error brk.c:(.text.__GI_sysconf+0xd4): undefined reference to `clock_getres' - remove improper comment - move stripping into do_ar resp compile-m for the sake of simplicity - make sure to build crti and crtn with PICFLAG check and test have to depend on test_compile wow. So why does test/ keep it's own copy of CFLAGS guessing etc? - do not run tests that are not available - don't test libcrypt stubs - the interp is an order-only prereq of lib-so-y - hint vi on the filetype while at it - do not test pthread if threads are not available - add error-counter, do not immediately exit if a testcase fails but print the overall error-counter at the end and exit accordingly. - remove the error counter - do not force LFS unto x86_64 folks vapier, you added this in r12384. What was the reasoning back then? - improve UCLIBC_LINUX_SPECIFIC compile-tested only, fixes libc/misc/statfs/fstatfs64.c:29: error: 'fstatfs' undeclared here (not in a function) - pull fix for unwinding from the NPTL branch (Johannes Stezenbach) Repair C89 compliance and severe whitespace-defects while at it. - poison non-standard keywords: Make sure that we can be built with non-C99 compilers, too. Use __\1__ instead. - fix asm and volatile keywords - fix inline keyword - trim any trailing whitespace - some more asm keyword fixes (Yann E. MORIN) - Fix powerpc pread/pwrite (Wade Berrier) pread/write wanted to send an 8 byte value in the syscall where only 4 bytes were allowed. - pull check-lxdialog.sh from linux-2.6.26 - should either be defined or callers should do_t_strip manually afterwards - flesh out helptext of DOMULTI. Put short, just leave it alone or keep all parts -- alternatively go help with lto if you have time. - remove a couple of duplicate includes - fix indentation - for extern inline, also take __extern_inline and __GNUC_GNU_INLINE__ into account - adjust range of valid grp buffer size to match pwd buffer size - honour EXTRA_CPPFLAGS Makes it easier to say something like make libc/sysdeps/linux/common/close.i EXTRA_CPPFLAGS=-P - add some helpful help text, as advertised. - the help target is phony - remove relocations for clock_getres - fix typo - remove posix_openpt relocation - remove gethostbyname_r relocation - whitespace fixes - fix typo - commentary typo fix - do not attempt to rm twice - clean targets are supposed to clean independently of any .config - add sync_file_range() Tested successfully on i386.. - sync_file_range(). Missed the i386 directory in previous commit - add script to generate lots of failing (random)configs rm -f STOP ; ARCH=i386 nohup extra/scripts/randconfig.sh & if you want to stop it, touch STOP - exec_comm_child can not return ever - remove non stdc path (old style definitions). No obj-code changes - posix_fadvise64 for i386 - take LFS into account and add fallback via fadvise64 - add posix_fadvise. Not yet tested most likely broken in advise64 - fix for r23427. Thanks to psm for mentioning this and sorry for the breakage - do not segfault if we end up with empty tables - silence some warnings while at it - both getopt gnu and susv3 want {bits/,}getopt.h installed. Closes #1297 - deal with ARM specific syscalls. Closes #2894 - remove debug cruft - Fix arguments to compare function. Closes #1081 - silence warning about possibly undefined preprocessor token - only compile them if the respective syscalls are available - ARMV5 can use STRD and LDRD access instructions but these accesses need to be 8 byte aligned. The dynamic linker's malloc needs to match this so structures become 8 byte aligned to void unaligned accesses. (71_all_uClibc-arm_fix_alignment.patch from gentoo) - arm eabi needs __UCLIBC_TRUNCATE64_HAS_4_ARGS__ (75_all_uClibc-arm-ftruncate64.patch from gentoo) - adjust helptext - expand documentation - add missing dependency on lt_defines.h - retry with some different locale if en_US happens not to be there - if we only have socket support then there is no resolver state: In function `__pthread_reset_main_thread': undefined reference to `_res' - RPC support currently requires either IPv4 and/or IPv6 support - fix !LFS case for i386 - add missing hidden_def - fix compilation of legacy mode - add prototypes - disable gettext support in obstack. In function `print_and_abort': obstack.c:(.text.print_and_abort+0x1b): undefined reference to `__dcgettext' - also clean .oS - add CONFIG_MIPS_ISA_MIPS32R2 (Julian Brown) - cast both times to double for consistency - remove files that are not either LGPL or Public Domain. - pull replacement funcs for fpmacros.c from glibc - fix typo - add __ieee754_log2() - add some more math functions (patch from gentoo/solar) - revert inappropriate part of r23478 - remove all *_hidden_proto(...) on install_headers - move libm_hidden_proto to the corresponding headers. Remove from callsites. Note that gamma_r is not provided by glibc, perhaps add a SUN specific knob later - revert r23469. If gnu getopt is disabled, then there is no getopt.h. In these cases the getopt stuff comes from unistd.h (which includes bits/getopt.h for us) - fix ISO C keywords - now passes all LTP tests - honour UCLIBC_HAS_SYSLOG - do not pass bitwise-or to the assembler. Closes #3164 - add a copy of user_regs - remove shadows declaration of struct st (already declared in function scope) - tweak helptext - fix compilation of UCLIBC_HAS_PTY && !ASSUME_DEVPTS && !LINUX_SPECIFIC - remove some duplicate includes - add missing const qualifier for !__NR_sched_setaffinity && HAVE_STUBS - avoid warning about undefined preprocessor token - fix whitespace - use c89-style comments Closes issue #5194 - add long double math wrappers (Ned Ludd) - tweak inclusion of asm/socket.h for linux-2.4 (Peter S. Mazinger) - disentangle REALTIME from ADVANCED_REALTIME (Peter S. Mazinger) - silence warning - hide relocation (Peter S. Mazinger) - Fallback waitid impl (Peter S. Mazinger) - sync obstack.{c,h} with glibc (Peter S. Mazinger) - move helptexts to their config symbols so that they are actually displayed TODO: trick kconfig into displaying choice help properly - wrap overlong lines - mention the architectures that currently support fenv(3). i387 works (could be that it works on x86_64, untested), sse code disabled. - implement log2() - add libc_hidden_def(clock_getres) as spotted by Ned Ludd - fix typo in previous commit - add/use variables to make build-tools configurable - Fix strtol*() with xlocale (on e.g. x86_64) (closes #2544) - revert bad hunk from (my) r22403 CRT need config too - fix building locale (pre- and generated, even parallel) - fix bad r23573 from egtvedt - sync comment to rule as pointed out by psm. - fix test. Tests are normal userspace and are _not_ part of the libc itself Thanks to Tobias Poschwatta for pointing out this error. - mention a FIXME for some make guru :) - fix errno setting (we're outside of libc here) - standardize fopen error message a bit - beautify hcompile.u - tidy up utils_install - reinstate hostutils target TODO: utils/* should be pulled in again to live in the normal buildsys.. - cut down on attempted pattern rule matches - prevent spurious rebuilds Previously this led to superfluous re-stripping and the re-ar'ing - Include stdio.h for the perror prototype, use constants from stdlib.h, tidy up old-style function definition. - add and use EXTRA_DIRS to wipe the test/locale/C directory - remove suspicious_dependency - make sure to match the start of the MAKE_VERSION - pull kconfig from linux-2.6.27 - remove bashism; don't install config/* to the target - .. and don't install the config dir, too - add signalfd() - fix return value - fix copy'n paste error - fix locale dependencies and make default locale generation less verbose. The verbosity can be set to the previous level by passing V=2 to make. - bump version to 0.9.30-rc2 - mark trunk as -rc2-svn This should fix malloc with debug and without threads. (Chase N Douglas) This should have been in r23660. Untested. - document environment variables for make(1) - guard socket calls with UCLIBC_HAS_SOCKET - des uses ntohl - fix toggling thread implementation. Previously the old headers were left in include/ leading to spurious compile failures. This is ugly as it can get (we resort to sneaking -L in for the moment) but good enough for now. The worst thing which can happen is that we ln these headers once per invocation of make, nothing more. If some installation of make(1) complains about the "-L" then wrap it in ifneq ($(findstring check-symlink,$(.FEATURES)),) - sync fix for scandir errno handling to scandir64 (r23600) Thanks to Peter S. Mazinger for mentioning this. - do not list non-existing files in the threads prerequisites - fix sigaction on older kernels (Michael Deutschmann) In issue #5554 Michael wrote: The implementation of sigaction on i386 for older kernels makes the system call using an inline asm element with two flaws: - do not include netlink headers if netlink is turned off (Michael Deutschmann) Closes #5544 - need to grab features before looking at eventually requested netlink support Thanks to Peter S. Mazinger for pointing out this (obvious) error. The __ASSUME_NETLINK from ricardw's r22531 references a non-existing variable in certain cases. I don't see how that could possibly work.. - delete_module() takes two arguments on linux-2.6 Closes #5644 - remove superfluous ';'. No objcode changes. - tidy up inline: ldso and syscalls are __always_inline (the latter would need more cleanup) - fix mips syscall (Atsushi Nemoto) - fix typo in r23808 - Print helptexts of choices. If a choice (but not it's children) has help, print that. If a choice's child has no help, print parents help. - add helpful help string - pull in prototype for memalign() - fix compilation if LFS is off and STUBs are requested - trim superfluous ';'. No objcode changes - bump version to 0.9.30-rc3 - mark trunk as BUGFIX-ONLY after 0.9.30-rc3 - fix another fallout from r23660 - fix use after free (Kevin Day) dl_cleanup will call do_dlclose with the handle. Inside of do_dlclose, the handle will ultimately get free'd. - minor shrinkage (-50b) - helper config symbol has to depend on thread support - improve readability, no objcode changes. Looks a bit like we wouldn't need to calculate the carry flag there? - whitespace fixes - Fix __user_locking with stdio buffers (Carmelo AMOROSO) Closes #5254 - jmp on coldfire accepts only address registers Closes #3824 - document more environment variables - tidy up indentation - less verbose make clean - Add temporary hack to wipe dep files even on clean for utils. utils lives outside of the normal build so this is needed until it is properly pulled into the normal system. - for !UNIX98PTY_ONLY we have to fallback to old-style pty's. Closes #6024 - update recommendation for pregenerated locales. - update name of locale-tarball. We will retroactively fill them in, eventually - adjust trunk version info - silence shadow warning - do not fail if mktemp is not available. Thanks to Peter Mazinger for the report. (r24023 from branch) - Remove linux-specific prototypes if asked to. - revert wrong r24049 - Remove linux-specific prototypes if asked to. - if ssp is enabled then make sure that __stack_chk_fail resolves - cleanup {,f}stat{,v}fs{,64} relocs - add hack to check if generating sysnum.h worked out - add __hot and __cold annotations Will spare us quite some likely()/unlikely() occurances. See http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html for details - fix args (untested) - Fix thumb2 PIE (Joseph S. Myers) This patch fixes position-independent executables (PIEs) for Thumb-2. In Thumb assembly, instructions reading pc give a value 4 greater than the address of the instruction, rather than 8 greater as in ARM mode, so the offset to the GOT needs to have the right offset. (The Thumb-1 code already gets this right; it's the code shared by ARM and Thumb-2 that needs fixing.) - make sure isspace() is exported. Thanks to Skinkie for noticing. - cosmetic tidy up of clean target - cosmetic tidy up of clean target - hide __libc_{f,}statfs. Thanks to Peter S. Mazinger for mentioning this fact. - hide some time related relocs - remove some bloat that was added in r23660 and subsequent r23698. The sbrk lock is only needed for LT.old - hide locks - revert 24148:24151 - remove fstatfs() and statfs() related headers upon request - make isascii visible again TODO: *_l() should go - Use runtime pagesize (Jeremy Kerr) Some powerpc machines can support 64k pages, enabled by the CONFIG_64K_PAGES option in linux. - use proper macro (no obj-code changes) - use proper macros - fix loop for checking ifaddr on both IPv4 and IPv6 - improve documentation of utils and hostutils - document environment variables used by the install_* targets. See their config helptexts for further detail. - only strip if cc compiled fine Avoids displaying an additional error from strip when your cc ICEs or fails otherwise. - install utils into the proper directories - emulate unavailable syscall getpgrp on e.g. ia64 (Stefan Assmann) - provide INTERNAL_SYSCALL for ia64 (Stefan Assmann, sassmann at suse de) - non-pic support for MIPS (Catherine Moore, clm at codesourcery com) - fix fpclassify, signbit, isfinite, isnan, isinf macros for long double math support - add rule to create preprocessor output for float- and long double math wrapper - remove whitespace - fix for !GETOPT_LONG - remove leftover from r13277 - capget() is linux specific; Sync helptext with current exclude list. - mark capset() as linux specific - pthread_attr_{g,s}etstacksize would depend on SUSv3 legacy but are not implemented anyway. - expand SUSv3_LEGACY - SUSv4_LEGACY part #1 (non-networking) - ethers only make sense if we want to play with ethernet addresses as in /etc/ethers (man 5 ethers) Assume that any of socket- or IP support indicate that need. - whitespace cleanup; no obj-code changes - fix typo in r24594 - fixup incomplete r24515 (fix redefinitions of posix_types for i386->x86_64 with linux >= 2.6.28) - make sure not to have relocs in Scrt1.o (Peter S. Mazinger) - make sure to pass the correct PIE flags to gcc (Peter S. Mazinger) - hide __dl_ldso__ (Peter S. Mazinger) - remove unavailable functionality upon request (Peter Mazinger) - commentary typo fix - make sure __user is defined when including kernel's sigcontext.h - also link librt with --as-needed and do so unconditionally to work around bugs in gentoo's QA. Just add UCLIBC_HAS_SSP to the "and" of link.asneeded to properly take SSP into account, if you prefer. - fix install_headers on hosts where ld does not support gnu hash-style but uClibc is configured to use it. - workaround oddity with position of function attributes - fix compilation of !UCLIBC_HAS_CTYPE_TABLES by merging duplicate bits into ctype.h - fix fallout from r24140 and r24160 for !CTYPE_TABLES - fix link failures coming from recently added, misplaced strverscmp. - use existing __stringify macro - we may need getdomainname internally - fix comment style to make it compile again - add note about "/etc/config/" and the resolver code per se. - scalb{,f,l} depend on UCLIBC_SUSV3_LEGACY - repair my r25322 that ment to deal with getdomainname()'s visibility - explicitely discourage to use pregenerated locale data. Rob Landley promised to provide them for all arches but didn't do that yet so disable it for now since they just do not exist right now (and furthermore cause more pain than gain). - fix weak ssp symbol on some arches (Peter S. Mazinger) Work around alleged binutils glitch with weak symbols on some arches. See binutils ML, weak psm and vapier. - also filter out headers-y - disable libcrypt tests if we have no libcrypt - remove dependency on GNU error functionality - remove superfluous $(strip) - do not pass -Wl with -shared in LDFLAGS_NOSTRIP (Peter S.

LD_PRELOAD Carmelo Amoroso (233): Added support for GNU hash style into dynamic linker Define _dl_assert in libdl only if __DOASSERTS__ is defined. Thanks to Peter Mazinger Fix build system to generate locale data instead of using pregenerated ones Added AVR32 support to uClibc. Signed-off-by: Hans-Christian Egtvedt <hcegtvedt(a)atmel.com> If uClibc's ld.so encounters text relocations in a shared library - one containing an object built without -fpic/-fPIC - then: ARM SHMLBA = (4 * PAGE_SIZE). Currently in uclibc arm used shm.h from common directory where SHMLBA = __getpagesize() Disable tst-ftime_l test if Extended Locale Support is not enabled, otherwise build will fail Some versions of gcc consider inline merely a hint. AVR32 depends on the system calls actually being inlined, so AVR32 needs to use __always_inline instead of just inline. The attached patch changes this for the system calls. Fix opendir problem when statically linked due to a missing initialization of the mutex field within DIR struct. When linked dynamically instead, __pthread_mutex_init will initialize the mutex itself. Without this fix, any call to readdir will stuck forever trying to acquire the mutex. I don't remember exactly why we decided to pick the caller's value of sa_restorer when SA_ONSTACK is set, but it seems to break LTP's sigaltstack testcase. Some users have reported problems with sigaltstack as well; hopefully this will fix it. Removed pointless initialization to 0 of DIR fields after having added memset. Thanks to Peter Mazinger for pointing this out. Make sh4 build works again adding a temporary work-around iby redefining __always_inline to inline until gcc 4.x.x will get fixed. Make sh4 build works again adding a temporary work-around iby redefining __always_inline to inline until gcc 4.x.x will get fixed. This patch solves a problem in dladdr caused by the wrong value of elf_resolve's loadaddr field for the main application. Test case to exploit dladdr bug Fix stack overflow in _ppfs_parsespec Added AI_NUMERICSERV flag and check if the string is not just a number when AI_NUMERICSERV flag set. Do not call _dl_de ug_state() before recording ld.so. Signed-off-by: Daniel Jacobowit <dan(a)codesourcery.com> Fix typos in comment Added support for ether_line, ether_ntohost and ether_hostton. Added related test cases. Fix file permissions Fix file permissions Call explicitely objclean-y when doing build cleanup. Remove 'find' command. It makes cleanup faster too. Khem Raj <kraj(a)mvista.com> writes: While compiling trunk on ARM with GCC 4.2 and enabling LDSO_GNU_HASH_SUPPORT I stumbled upon this problem.

Remove gcc warning due to missing prototype for 'testandset' Add unifdef host tool to clean target Do not check retbuf if realpath returns NULL Convert to UNIX format Added a bounch of locale fixes. Remove automatically generated header when doing make clean Synch extern declaration with definition provided in __uClibc_main.c Fix build failure due to missing 'smallint' definition by adding <unistd.h> header file. Fix build failure due to missing 'smallint' definition These are source files built on the host. Fix the ELF magic number for SPARCV9: by Friedrich Oslage <bluebird(a)porno-bullen.de> Fix typo in macro for tls access model Fix some compiler warnings Make locale_headers only when doing pregen and not headers due to dependencies against sysnum.h Fix makefile target to run test when there are some shell script. SImply do not include SHEL_TESTS among RUNTIME_TESTS, because shell script have a their own rule to be excuted. The runtime evaluation by using the $(shell ...) command doesn't work due to immediate expansion of shell function. Currently only nptl tests have shell script, so this problem have been never discovered before. Include errno.h from kernel headers instead of using internal errno_values.h otherwie some errno will be missed (i.e. ENOKEY used in libusb) Fix the test build system by installing headers on a local folder instead of using internal headers. sh4 don't need to cope with older RLIMIT implementation. Added several tests for locale support (8 bit and multibyte UTF-8) Added missing tests for locale with multibyte encoding Removed wrong preprocessed files Remove .depend when doing distclean Fix SH ldso sequence startup. Follow sh asm convention to indent the instruction into the delay slot. (glibc community refused to apply a my patch for this :-) ) Use getdents syscall if kernel provide supports for this instead of relying upon getdents64. Revert latest changes. Instead of applying this work-around a proper fix should ensure that statically linked mutli-threaded binaries take always the proper locking implementation. Hush compiler for extern inline warnings by using __extern_inline macro, this also makes gcc 4.3 happy. (Taken from NPTL branch) Fill in termios_p data structure only if ioctl syscall doesn't fail (as glibc indeed does). Fix problem in vfprintf when assertion are enabled. Here follow the output of my analysis: __stdio_fwrite expects at least 1 bytes. fputs_unlocked(S,F) calls fwrite_unlocked and this calls __stdio_fwrite only if bytes to be written are > 0, otherwise simply returs 0 (that is correct). During the parsing of format spec it could happen that __stdio_fwrite is called passing an empty string and with assertion enabled it will abort. Fix some locale multibyte tests failures ad below: Add optimized memcpy implementation for sh4 (from Stuart Menefy @STMicroelectronics). This implementation is based on 'backward copying'. Add INTERNAL_SYSCALL macros for sh Fix posix_fadvise[64] functions to return the error number in case of failure instead of -1 and setting errno, according to SuSv3 (IEEE Std 1003.1 2004 edition) specification. Use __always_inline for _dl_gettimeofday as well. Add work-around for powerpc. ldso: removed dead code. Add globally __stringify macro in libc-symbols.h. Remove all other duplicated definitions. sh: Fix SYSCALL_INST_STRx to work for SH-2[A] core by using the __SH_SYSCALL_TRAP_BASE macro. i18n: Fix mbrtowc function to handle 0xc0 and 0xc1 sequence. ldso: do not use hard-coded fd in _dl_dprintf. Use dl_debug_file consinstently. libdl: use stderr consistently. ldso: allow undefined references to weak symbols Fix comment. sh_ldso: Fix typo: missing semi-colon. Fix compilation problem whit the following config options: UCLIBC_HAS_STRING_GENERIC_OPT=y UCLIBC_HAS_STRING_ARCH_OPT is not set by making WORD_COPY_FWD macros visible. Fix scandir function to reset the errno when the selector returns zero(no entries) modifying the errno. The attached test case implements a dummy filter that returns alway no entries, but change the errno. scandir is not expected to fail, just returning 0 entries. Move _dl_iterate_phdr into libc.so.0 and libc.a (as glibc does). Currently we have an implementation in ld.so and libdl.a. Fix typo: missing ) Changed Copyright and License statement according to COPYING.LIB.boilerplate Changed Copyright and License statement according to COPYING.LIB.boilerplate Make wcsxfrm visible also when LOCALE support is disabled. This patch fixes locale-mbwc test failures when __UCLIBC_HAS_LOCALE__ is disabled and __UCLIBC_HAS_WCHAR__ is enabled. The only locale available when __UCLIBC_HAS_LOCALE__ is disabled is the C locale, the others locale are skipped. Make __UCLIBC_HAVE_ASM_CFI_DIRECTIVES__ visible in case the arch supports this feature. SH4 will use this in some aseembly files for the NPTL implementation. Add now safely on trunk. Fix wcswidth function when LOCALE support is disabled while keeping WCHAR support enabled. This solves two testcases: tst_wcwidth and tst_wcswidth. Two other absolutely safe change that will be used by NPTL, aimed to simplify merge. A missing change when we recently released a lot of fix on localae support Added do_awk commanf for invoking awk parser. It will be used for generating some file on-the-fly on the NPTL case. Go deeper while cleaning string directory to remove TARGET_SUBARCH implementation too. CLean librt/*.oS too (NPTL will add some). Move kernel-features.h header from the linuxthread directory to a common one (libc/sysdeps/linux/common/bits) so that any function can access to supported kernel feature (i.e. getdents). Silent compiler warning regarding undefined macro ldso: do not comment out unused variables, just delete it. libm_sh: Re-added sh specific files erroneously removed recently, and moved under a better folder. libm_sh: fix libm build for sh ldso: performs bootstrap relocations only if required by the arch. It is controlled by ARCH_NEEDS_BOOTSTRAP_RELOCS macro. Follow naming convention for tst-regex2 input file. All others are .dat suffix. Remove check for the relocation type check in the resolver, from all archs. Added sysdep.h and sysdep-cancel.h for linuxthreads ARM Re-add _ISbit macro required to build libstdc++ from gcc toolchain. Pass NO_LONG_DOUBLE flag to basic-test when LONG_DOUBLE support is not enabled in uclibc to fix build. sh: Fix __SH_SYSCALL_TRAP_BASE for SH2A architecture Fix typo. Linuxthreads_old and NPTL must be mutually exclusive. Fix my previous commit to use preprocessor in the right way ! Use gcc built-in defines for detecting SH cores instead of uclibc config option macros (aligning SH to all other archs). Make long double support available for sh too. Use __always_inline instead of __inline__ Added string.h header for strerr prototype. Fixed makefiles inclusion flow to pass actual configuration variable values. Test build system modified to be similar to uClibc one: * test custom logic moved from Makefile to a new Makefile.in (to be included by Makefile). * Makefile same for all tests and just used for including all other needed makefiles. Add position independent code for crt1.S. This will generate a Scrt1.o that is linked to executabled when compiled as PIE code (position independent executable) without requiring relocation in .text section (not allowed on uclibc/sh4).

unused-but-set-variable nptl: fix compiler warning due to missing prototype libc: elf: explicitly include uClibc_page.h to make PAGE_SIZE visible Chris Metcalf (1): Make _dl_dprintf buf non-static to avoid multithreading bugs. Chris Packham (1): libc/sysdeps: add __kernel_long and __kernel_ulong Chris Zankel (18): Add myself as the maintainer for the Xtensa architecture. Omit adding 'OUTPUT_FORMAT' to the libc.so linker script if the architecture didn't provide one (Xtensa, for example, is such an architecture). Xtensa: Provide an architecture specific sigaction and sa_restorer function in libc to avoid having to place executable code on stack. xtensa: the size of the elf_gregset_t array is actually 128. xtensa: Fix spill routine. xtensa: The Xtensa-specific strcmp.S file is testing the __UCLIBC_HAS_LOCALE__ macro but it does not include <features.h>, so that macro is never defined. This causes problems with strcoll when locale support is enabled. xtensa: The Xtensa port needs to define the __UCLIBC_TRUNCATE64_HAS_4_ARGS__ macro so that a dummy argument will be inserted before the long long length argument, which is expected to be in an even/odd register pair. xtensa: Stack unwinding on Xtensa requires that the return address register always be valid. This patch fixes a part of ldso that had been using an Xtensa CALL0 instruction to get the current PC value, which temporarily clobbered the return address register. The revised code just loads the address of a label in the code. See my change to GCC from 2007-12-20 for more info (http://gcc.gnu.org/ml/gcc-patches/2007-12/msg01023.html). xtensa: add sigcontext.h xtensa: use atomic instructions instead of a syscall xtensa: add a set of atomic intrinsics xtensa: fix a misnumbered register in sigsetjmp ldd: ELFCLASSM was not defined for the Xtensa architecture xtensa: add a stub user.h file xtensa: sysdep.h needs to include sys/syscall.h xtensa: add missing atomic intrinsics test/math: add libm-test-ulps-xtensa file xtensa: fix setjmp that didn't save all registers correctly Christian Bruel (1): libm_sh: add optimised assembly implementation of lroundf and lrintf Cristian Morales Vega (1): Do not define unimplemented functions Cédric VINCENT (1): ldso: fix standalone execution on x86_64 architecture Dan Moulding (1): NPTL: Fix undefined reference to PRIVATE_FUTEX with 2.6.18 kernel Daniel Jacobowitz (1): mips: do not save variables in "hi" or "lo" across system calls Daniel Mack (11): extra/Configs/Config.in: drop "default n" lines libc/inet/resolv.c: comment on #endif lines inet/resolv: add ns_{put,get}{16,32} inet/resolv: add ns_name_pton, ns_name_pack and ns_name_compress inet/resolv: Add dn_comp inet/resolv: add dn_skipname and ns_name_skip inet/resolv: add ns_initparse, ns_parserr, ns_skiprr and ns_msg_getflag inet/resolv: add res_mkquery inet/resolv: add res_ninit and res_nclose include/resolv.h: provide __res_state._u even if !__UCLIBC_HAS_IPV6__ inet: build all res_* and ns_* functions conditionally David A Ramos (2): Fix ctime() standard compliance bug inet: add ether_aton testcase David Anders (2): fix ARM types that are known to have MMU's to select ARCH_HAS_MMU add ARM 7TDMI to processor selection list David McCullough (90): DIRS was not set in this makefile and could be inherited from the environment. Allow Config to override OPTIMIZATION flags. uClibc working with 2.0.x and 2.4.x m68k uClinux kernels, the PIC stuff in crt0.S may not be quite right yet. ptrace for m68k debugging. uClinux 2.0 doesn't have the poll system call, just check for the definition before using it. The rules to build sysconf_$(TARGET_ARCH).c were broken when cross compiling. Added "psignal" function Added /etc/hosts processing (parses everytime like a real one :-) Added res_init and res_query Reduced the size of sigsets to the minimal needed. Apart from the size, it has the added advantage of giving the C++ build of m68k-elf-gcc a clean bill of health. New crt0.S with all init done in 'C' code. Added in support for C++ contructor/destructor tables. g++ compatible math defines. For some reason the fancy attribute tags were not working on m68k so I followed environ example which uses asm and it seemed to fix the problem nicely. Do not remove const and extension when compiling with the elf tools. Add an empty DIRS target incase it gets inherited from the env. Clean up some issues for building on m68k. Quick fix to setjmp/longjmp/sigsetjmp etc to make them work. This should really be fixed to fall into line with the other archs. Code did not match the prototypes, from what I can tell it should be using size_t as the header files have it already. Change the last 2 "make" invocations to use $(MAKE). Up the m68k defaults a little so that uClibc will support a g++ build. ldso build always used $(NATIVE_ARCH)-uClibc-gcc, which doesn't work for cross build (ie., m68k under i386). Changed it to use $(TARGET_ARCH) instead. Changes needed to build the ldso dir for m68k. I haven't tested it, who knows if it will work, it just compiles cleanly :-) The m68k-elf compiler chokes on this code when compiling for PIC as compile_regex is one big function (relative function calls further than cpu32 can do). Fixed vfork so the child doesn't trash the parents return address. Added this guy, nothing needed here really. the minimum needed for now sysdep.h was not providing all the needed bits to build working asm with some compilers, so define any macros we need that are not defined already. Changes to support autogenerated syscall.h Changes for new auto-generated syscall.h If HAS_MMU is false, then use asm-$(TARGET_ARCH)nommu rather than asm-$(TARGET_ARCH) as the link for include/asm. Added stpcpy and strcasestr along with some code to test them. Fixup the atexit weak alias for elf, need to include <features.h> to get the correct value for the HAVE_ELF define. The weak_alias macro was not genertaing asm with the correct alias names. The main part of the C++ support is the definition of __BEGIN_DECLS and __END_DECLS in this file based on the __cplusplus define. Added __BEGIN_DECLS and __END_DECLS to the files that didn't have it and that I could see needed it. Fixup the pipe system call for the SH target. The FD's are returned in registers. Make sure the weak aliases are defined before the functions/vars they use as stubs, otherwise, some compilers (ie., m68k-elf) tie them to the local symbols and the weak aliases do not work. Fix a couple of warnings Added sigset_t casts so we behave like the other platforms. Add hstrerror, it just points to strerror like h_errno. Add in changes from philipc@lineo: Add cmsg_nxthdr function for the cases where the headers do not so it inline. Make _PATH_VARRUN actually point to /var/run. With all the headerfile changes, some functions didn't get there arg types fixed up. Hack the 68000 last ditch abort to work for all 68000 targets. Add in an ARCH_CFLAGS placeholder so scripts can mod it. merged the two startup files so that uClinux people always get the correct arg processing whether they are using PIC or not, and vice-versa for the MMU folks. Add in support for inet_netof, inet_lnaof, inet_makeaddr and hstrerror. Add sbrk and friends Fix bug in setjmp (jmpbuf changed size) Fix simple malloc to work on systems with an MMU Don't print an error if the utmp file doesn't exist, getutent will return NULL as expected. Added insque/remque support The resolver is still using the old API so we cannot use the new resolver version numbers or apps get confused. Clean up builds on "sh" to use the right ARCH dirs * Added /etc/shadow support (Config selectable) * Moved some file paths from code into <paths.h> Add in clone (untested) Added locale and lastlog Added a dummy romfs target so this stuff slots nicely into the uClinux distro. Fixed broken shell syntax. Changes so that this file builds if we are not using threads. At some stage I was getting conflicts on the SH platform with the two i_am_not_a_leaf functions, changing the name of one is harmless and fixed the problem at the time. Not entirely sure it's still required. pread and pwrite were broken in several ways: Fix a number of compile time warnings so that uClibc will build with -Werror using a 3.0.4 version of the sh-linux-gcc compiler. Fix some more warnings for non-thread-enabled compiles. Added __kernel_fsid_t to satisfy some apps that need it. Definitions taken from 2.4 kernel sources for each of the platforms. Fix a delay slot problem, this gets some apps working on SH, a good number are still seg-faulting. Somehow the bit of code that add the offset of envp to argv got lost and envp was a very small number and not an address. I think this fixes most of the SH platform. If the initfini.pl script changes, regenerate the crt[in].S files. Fix a memory corruption bug. Fixup JMPBUF_UNWINDS so that is will compile if used :-) Add in clone and make the assembler PIC/msep-data friendly. Fixup thread support for the 5200/5307 coldfire platforms. If the wait failed in pclose it would return a random status code instead of -1 as expected. add brk for m68k If floating point was enabled, setjmp would write to memory well past the end of the buffer. Using -g when doing the initfini compilation breaks the SH4 case pretty badly. I have removed -g for all platforms as I suspect no one wants it for the initfini creation process. Use a define for the path to /etc/TZ updates to the uClinux-dist romfs and uClinux shared library targets. Fix FP handling alignment problems on ARM platforms without an FPU, patch from Vadim Lebedev <vadim(a)7chips.com>. restore the coldfire changes Fix the double sub #48, should have been an add :-) fix coldfire/68000 support properly this time, ifdef logic was back to front. more uClinux shared libs fixups Fixup __libc_open to use varargs and match the prototype. Some small fixups for the h8 support and add the h8s platform support. setjmp was trashing r12 which is bad and can cause apps to crash if they are using r12. r12 is supposed to be preserved across C function calls. r0-r7 are trashable :-) Sleep was returning the wrong value because: Add in a default file for m68k. Microblaze port from the uClinux-dist, contributed by John Williams <jwilliams(a)itee.uq.edu.au> Make sure we remove -fomit-frame-pointer from the ldso build. It's inclusion will cause the loader to crash when jumping to the application. David Schleef (111): test proggy for strtol, strtoul Reimplemented "make install" target. I left the old one as-is, under the assumtion that someone will get confused if it suddenly changes. First cut of MIPS port Copied bits/*.h from Debian MIPS libc6-dev 2.2.2-4 package. Header cleanups to fix compilation. Mostly a hack, pending figuring out the best way to do some things. Copied sgidefs.h from Debian libc6 2.2.2-4 for MIPS. Should go into the main include/ directory, but we'll hide it here for now. Needed for libm termios test program, since I'm having difficulty on powerpc Test to check for proper stat mangling. The mmap syscall has 6 arguments, which has various implementations on different architectures. Random quick-and-dirty evil malloc checker. added __GNUC_PREREQ() macro Added powerpc-specific mmap syscall, 'cause we're special. Random change to get a log message: Previous change is to make this header more compatible with the kernel and not with glibc. Changes to make types.h more compatible with the Linux kernel. Added -Wall Fixing flak from the directory rearrangement Nasty hack to get around inconsistency between dynamic linker entry and kernel entry to crt0.o. Makefile targets to symlink arch-specific headers into include/ (only used on mipsel.) Added definition of __THROW Add warning message if Config doesn't exist Change to allow compiling against unconfigured kernels. Creates symlink to include/asm-${arch} instead of include/asm. Added additional cleaning Changed dependencies of gcc-uClibc.h to ../../Config instead of clean Fix to autogen bits/syscall.h, like i386 It is now autogenerated Need to include sys/syscall.h because of other changes Debian package building scripts Get rid of warning messages and spurious diffs remove bits/syscall.h when cleaning *** empty log message *** The prototype Config file for x86 was changed to Config.i386 Install a link for /lib/ld-uclibc.so.0 Make shared library installation conditional Small fixups for powerpc First cut of PowerPC port. It works for hello world, but has lots of debugging information is still there. Added #ifdef DEBUG where appropriate. Fixed icache clearing during _dl_init_got(). Added a few more reloc types. Added out-of-range check for R_PPC_REL24. Add test for proper realloc() behavior. The previous termios.h strongly appeared to be from a different architecture. PowerPC has a different kernel interface for termios. Grrr... fixperms needs the correct name for ld-uClibc Better rule for locating dynamic linker Changes to build cross-compiling libraries Fix typo. Better generation of control, fix up DESTDIR Fix the /lib link Changed uclibc-gcc to uclibc-toolchain. Added fixups for changes in the Makefiles. Need to create $(SYSTEM_DEVEL_PREFIX)/usr/bin Change name of package to uclibc-toolchain. Various changes following the Makefile changes. Add a cvsignore for this dir Fixes for finding appropriate kernel headers, changelog entry Little script to create a properly-named snapshot for Debian packaging Fix problem with version naming include/bits from glibc-2.2.4-1 Merged patch from pre-glibc-2.2.4 files depend on kernel-headers, not kernel-headers-2.4 Disable posix threads support Add missing <errno.h> _mmap.o should be added to libc.a, not crt0.o Added .cvsignore Added winsize structure from before glibc-2.2.4 update Limited Debian architectures to the ones we can actually build. Improved mksnapshot script; now adds a bogus changelog entry. Added fixlinks script that automatically converts symlinks to conform to Debian policy and updated rules to use it. Added another bogus man page, prolonging the pretense that I'll actually write real ones. powerpc/elfinterp.c: Powerpc works now. Major rework; most relocs should work now. R_PPC_JMP_SLOT correctly being lazily relocated. hash.h: Added a field in elf_resolve to store a ppc-specific address. boot1.c: Added debugging code. Disabled check that fails on powerpc because the string literal requires a reloc that isn't performed. Added check to ignore d_tag if it is out of bounds, as has been observed with powerpc binaries. Enable ld.so on powerpc Fix common C ambiguity. Change the output filename to correspond to the package version. Notes about how powerpc/bits was constructed. Added build-stamp for Debian Updated notes Don't define _GNU_OBSTACK_INTERFACE_VERSION, because we don't provide obstack. Added a few items on my wishlist, removed some stuff that is finished. Debian upload Fix build-depends to use kernel-headers-2.4. Should satisfy more autobuilders? Notes on Build-Depends strsignal() is a GNU extension Fix dependencies Fix calculation of PLT entry index. Caused segfaults on second call of a lib function. Remove unused file Fix buggy R_PPC_RELATIVE relocation. Symptom was that strings internal to a library were not relocated correctly, specifically sys_errlist[]. Rewrite vfork() as C, should now work. Changed longjmp.S and setjmp.S to use GCC's internal ppc-asm.h, and added macro to disable FP save/ restore in longjmp and setjmp. Fixed name of _setjmp() (was __setjmp). Fixed _setjmp to be PIC. Disable ldso directory if DODYNAMIC isn't true, in addition to HAVE_SHARED Fix: libuclibc-dev should depend on libuclibc0. Elaborated descriptions. libhowdy.so needs to be compiled with -fPIC Fix TARGET_CFLAGS to include -fPIC when needed. Libs were being compiled without -fPIC. Removed TARGET_CFLAGS definition, since it was moved to toplevel Rules.mak update my list A little script to strip out unused portions of shared libs. Update version mksnapshot: updated version and filenames. control.in: changed dependency from kernel-headers to kernel-source packages. rules: force HAS_MMU=true, change mipsel to mips, untar kernel-source package include directory and use that as kernel source Fix typo Try adding mipsel to the architectures Additionally remove libc/tmp Special rules for mipsel. Force some variables in Config, in case they're wrong (they are.) Remove Config during clean. Build fix for arm Check in new debian snapshot Account for new upstream version. Fix shlibs, because they were broken. Add INCLUDE_THREADS to Config. New Debian snapshot. The release has ld.so for mips fubared. Removed handling for R_PPC_REL24, since it is deceptively useless. Make assembly code PIC-compatible. use ds account on cvs.uclibc.org use uClibc_config_fix.pl for configuration Change branch to fallthrough. Unclean, but it removes last R_PPC_REL24. updated to 0.9.11 updated kernel source package to 2.4.18 uploading new snapshot Make sure that CROSS="" for native building. Moved old README to INSTALL, and wrote a new README that is much more like an introduction to the project. fix mksnapshot and update documentation. update to last Debian upload. Dumbass Debian maintainer forgets to check stuff in. Make ldd work even more like GNU ldd by appending dummy load addresses Update CVS to Debian 0.9.18-1 package Denis Vlasenko (264): syslog.h: allow prioritynames[]/facilitynames[] to be defined const (selectable by #defining SYSLOG_NAMES_CONST) des.c: move 0.5k of static data on stack, they are used only temporarily by des_init. include/sys/mman.h says that msync exists only on MMU. Make msync.c agree on this. execXp should go to next PATH dir on any error except ENOEXEC, not just on ENOENT (in particular, on EPERM). At least glibc does so. Fixing this. Remove stray code alignment (.align 16 and .align 4 directives) from i386 and x86_64. introduce __uc_malloc, so that users can intercept libc internal OOM. convert des.c to use __uc_malloc (-70 kbytes of bss) patch #3: make resolv.c use __uc_malloc make pwd_grp.c use __uc_malloc make utent.c, getpass.c use __uc_malloc make getnetent.c, md5.c use __uc_malloc make regex_old.c, ruserpass.c use __uc_malloc, replace "buf = malloc(BUFSIZ); if (!buf) abort();" by __uc_malloc elsewhere. sgetspent: add missing free/__uc_malloc calls (spotted by Peter S. Mazinger <ps.m(a)gmx.net>) add libc_hidden_xxxx for __uc_malloc fix assembler error. libc_hidden_data_def cannot work on COMMONs, thus need to initialize stuff with 0 to force it into bss. All hell can again break loose if future gcc will be smart enough to ignore it. Fix author name and copyright notice in __uc_malloc.c realpath: reduce stack usage from 3*PATH_MAX (12k) to 1*PATH_MAX (4k). reduction is achieved by direct use of user-supplied PATH_MAX sized buffer for result (without intermediate copy) and changes in copy_buf[] usage - now it is used for both "source" pathname and link name (it works because they have to be less than PATH_MAX combined, otherwise we return NULL). add hidden_proto's for __uc_malloc (patch by Bernd Schmidt <bernds_cb1 at t-online.de>) Factor out the core of vprintf() into separate function vprintf_internal, so that: * vprintf() does locking and __STDIO_STREAM_TRANS_TO_WRITE thing, then calls vprintf_internal * vsnprintf, vdprintf.c, vasprintf.c use vprintf_internal directly Remove vestigial locking init from sprintf routines. restore erroneously removed hidden_def for vdprintf fix breakage in old_vfprintf case even more fixes for vda-made breakage in vXXXfprintf (pointed out by Peter S.Mazinger) remove "register" from _vf[w]printf_internal declarations too Functions should be either exported in public .h files and marked with libc_hidden_proto/def(), or not be exported in .h files and be hidden (or even static if possible). We have five functions which violate this. Fixing: amd64 string ops: replace some instructions by smaller ones, e.g. testb $0xff, %cl -> testb %cl, %cl amd64 string ops: use alignment more carefully, and comment it. By capping max padding to not be bigger than three next insns, we avoid having ridiculously big NOPs like this one: reinstate external visibility of inet_ntoa_r, and add it to arpa/inet.h header. build system: improve install_headers. Now it uses dedicated script instead of inline makefile commands, which helps readability. It also installs asm[-generic] and linux subdirs from kernel headers (previously it had to be done separately). Lastly, it passes each uclibc header thru unifdef, which strips #ifdef UCLIBC_INTERNAL conditional from headers. Currently it's a no-op (no such #ifders in tree). The plan is to have libc_hidden_proto(foo) migrated to headers and guard them by these #ifdefs. Experimentally move libc_hidden_proto(time) to time.h. The only code change observed is actually a case where we were not doing that as needed: __uc_malloc: remove stray semicolons build system: use a bit more aggressive gcc/ld optimizations, mostly related to ELF section ans padding, not code gen. Resulting reductions in size (only biggest ones are shown) uClibc.t4 - new, uClibc.t3 - old: install_headers.sh: detect a case when kernel headers are already installed in target dir, and dont try to copy them again Rules.mak: fix -falign/-malign mixup guard against older ld's not understanding --sort-section alignment install_headers: properly quote things install_headers: do not exit if unifdef "fails", it's ok Split kernel headers installation from "make install_headers". It is "make install_kernel_headers" now. realpath: do not set bogus errno when readlink fails. test-canon: stop checking realpath buffer in case realpath returns NULL (the buffer contents is undefined); also check errno more thoroughly (bugs were seen slipping through) fix "make install_kernel_headers" to not create asm-generic for 2.4 kernels. Moving libc_hidden_proto's into #ifdef UCLIBC_INTERNAL block in string.h and strings.h. This caught unguarded string ops in libc/inet/ethers.c __ether_line_w() function. suppress "asm declaration ignored due to conflict with previous rename" warning. It seems to be bogus. Comment contains extended description. add an URL to relevant gcc bugzilla entry Introduce and use small[u]int type. Changes in size: getopt: do not needlessly use static structure. Reorder structure members and change some of them into smallints to reduce bss and text: text data bss dec hex filename - 2403 12 40 2455 997 libc/unistd/getopt.o + 2252 12 0 2264 8d8 libc/unistd/getopt.o replace "if (p) free(p)" by just "free(p)" - free(NULL) is safe. convert two more static ints used as flags to smallints arm memcpy: fix the case when src=dst __uClibc_main.c: save ~70 bytes by not checking that /dev/null is indeed a char device with correct (maj,min). (If it's not such a char device, the system is screwed anyway, nothing can be done about it...) Slight size reduction by use of smallints/consts: Makefile.kconfig: whitespace fix top-level Makefile.in: add TODO fix fallout from string.h libc_hidden_proto removal add missing includes of unistd.h for smallint usage remove a few duplicate includes of unistd.h fix compile breakage in libc/string/wcscasecmp.c by adding include <wchar.h> in strcasecmp.c build system: stop creating ugly double-slash symlinks like fenv.h -> ../../libc/sysdeps/linux/i386/bits//fenv.h Rework smallint machinery so that it will reliably fail to compile even if arch overrides smallint size. Makes it easier to spot bugs on such arches. suppress a few "might be used uninitialized" warnings. No code growth. fix fallout from libc_hidden_proto removal libc/inet/addr.c: fix broked indentation and bad style. No code changes. libc/inet/resolv.c: use ip6.arpa instead of ip6.int for reverse IPv6 DNS resolv. rfc4159 mandated this 3 years ago. Closes bug 1020. fix bug 1577: '`' is not an acceptable digit for strto[u]l(). Code size is not changed on i386. libc/stdlib/stdlib.c: fix whitespace damage. No code changes (verified with objdump) dlfcn.h exists only if __HAVE_SHARED__ ("we are built with shared lib support"), not when !__HAVE_NO_SHARED__ ("arch can theoretically support shred libs") Rename HAVE_NO_SHARED to ARCH_HAS_NO_SHARED, otherwise it's too confusing with HAVE_SHARED fix trivial mismatch in return type of build_wcs_upper_buffer() (int/enum). clases bug 3234. Remove __PRINTF_INFO_NO_BITFIELD hack, UCLIBC_INTERNAL can be used instead, and it's slightly shorter. Also removes stray macros from public <printf.h> header and uses spaces for comment indentation. Fix bug 575 and other small problems noticed along the way. The bug: this blocks in syslogd is stopped: #include <syslog.h> int main() { int i; for (i = 0; i < 10000; i++) syslog(LOG_INFO, "Testing, disregard...................."); return 0; } Fix: set O_NONBLOCK on fd to "/dev/log". Other fixes: do not try to write to fd -1, do not spin forever or EAGAIN, use constant sockaddr instead of recreating identical one each time, eliminate one intermediate function (SUGPIPE sig handler), use smallints where appropriate, add a few comments. syslog.c: fix indentation and style. No code changes. syslog.c: fix a buglet in prev-last commit: logic inversion in closelog close bug 473: 1. names with two consecutive dots are not valid 2. if name ends with a dot, dont try appending search domain(s) alos a few small optimisations are here. Fix spurious testsuite failure Heed a warning: "string" was assigned to char*, changing that to const char* shrink getopt a bit by using smallints. Run tested (busybox testsuite) Fix failure in test/inet/gethost_r-align: we were closing a FILE, but did not record that fact by setting a variable to NULL, and then we used it for reading! While at it, small reduction in bss. Run tested. Use more natural way to return a value in __read_etc_hosts_r: Fix hard-to-rigger locking bug in vsyslog(): SIGPIPE handler was attempting to re-acquire an already taken lock. While at it, stop checking for sigaction failure which is not possible here. Sizes: Document the reason why ether tests in testsuite may fail. No code changes. Remove superfluous attribute_hidden from function definition. I seems to produce spurious warning: libc/inet/resolv.c:1549: warning: 'visibility' attribute ignored on non-class types (seems like gcc bug) and it is not really needed - attribute_hidden was already specified in function _declaration_ so it is not necessary here. libcrypt/md5.c: Make sp, ep and p variables automatic. There is no point in having them static, they never use their values retained from previous call. Replace strlen(__md5__magic) etc by compile-time constants. remove a trivial comment. no code changes des: des_setkey always returns 0, there is no point in checking whether it returns 1. #include <ifaddrs.h> should be #include "ifaddrs.h" New .config option UCLIBC_HAS_STUBS, enables fork() stub on NOMMU implement getgrouplist() getgrouplist(): ...add files which I forgot to add. libc/inet/getaddrinfo.c: const'ify some data; avoid using zero-filled constants in bss: make getaddrinfo to NOT query DNS for IPv6 address if host is in /etc/hosts and it has IPv4 address there. The most common example is "127.0.0.1 localhost". We don't want "ping localhost" to stall and time out on IPv6 queries to, say, inaccessible DNS server, right? getaddrinfo.c: reformat. no code changes getaddrinfo.c: improve readability trivial code shrink by making some strings static resolver: trivial code trasformations for readability. No logic changes. Code size is the same too. resolver: fix part of bug 1468: "gethostbyname() fails if DNS server returns more than 23 addresses" resolver: partially fix bug 660 - do not treat negative response as error __dns_lookup: document and optimize a bit resolver: reinstate searching if search domains accidentally nuked in one of recent commits :) fixing resolver, part 1 fixing resolver part 2: make _res structure members configurable. we don't use most of it anyway. fixing resolver part 3: fix completely bogus locking in __dns_lookup. resolver: more locking fixes. resolver: make getaddrinfo actually respect _res.nsaddr_list; add largish comment explaining what we are doing, and why; fixes to make IPv6-only resolver possible resolver: improved support for overriding DNS server addresses in _res structure. Used by busybox's nslookup. resolver: fix some previous TODOs, add new ones. resolver: move large code blocks to arrange related functions closer. almost no code changes resolver: separate gethostent and gethostent_r into two .o files; delete two stray files which compile to nothing resolver: use timeout of 5 (glibc uses that). delete some duplication in constants. libc_hidden_proto removal, just a few functions libc_hidden_proto removal, a few more functions next portion of libc_hidden_proto removal Last portion of libc_hidden_proto removal. Appears to build fine (several .configs tried) deal with TODOs left over from libc_hidden_proto removal (fixes build with locale enabled) fix apparent typo (unnoticed for long time, probably because it didn't affect little endian arches) fix ioperm build problems caused by libc_hidden_proto removal fix "make install" with relative PREFIX fix "make utils" build failure in ldconfig (undefined reference to 'getopt') fix some unneeded PLT references libc-symbols: improve comments and make macros a bit more readable. no code changes signal ops: avoid calls through PLT for __sigXXX ops linuxthreads.old/manager: pointless style fixes, no code changes libc/string: need additional work to remove libc_hidden_proto's properly reduce sigset_t size for 128 bytes to 64 bits: shring sugnal-relared stuff a bit. BTW why constant memset is not inlined by gcc? fix improperly hidden fwprintf. make two data objects static. fix improperly hidden fputc_unlocked add libc_hidden_proto(__cmsg_nxthdr) for mips rpc: ifdef out xdrrec_{get,put}long if int32 == long, otherwise use xdrrec_{get,put}int32 + trivial transform. eliminate warnings. des: small shrink + eliminate a warning rpc: should check against max for int32, not int gethostbyname can use gethostbyname2, saving one nearly 0.5k static buffer random: use smaller data fields where appropriate rpc: constify data, localize unnecessarily static data constify more data l64a: shrink by 13 bytes, and -1 reloc optimize signal mask ops. comment out "impossible" errors fix sigset_t size for mips (it's the only arch with 128 signals). fix _NSIG for it. better document what's going on in sigaction(). seems to not induce any actual code changes (sans mips). remove checks for "impossible" errors, clarify uses of unoptimized sigXXX ops (they check signo), use faster sigops where approproate. on Bernd's request, remove commented-out code snippets hostid: improve extremely unreadable parts *: remove checks of sigaction and sigprocmask results in cases where they clearly can't fail: sigaction(known_good_sig) sigprocmask(known_good_how) resolver: make new name resolutions reread /etc/resolv.conf if 256+ seconds passed since last read; fix cases where we switch to next search domain instead of switching to new server optimize ip4/ip6 combined cases; rewrite for(;;) loops so that it's clearer what's going on; document buffer usage; add TODOs and FIXMEs (for one, gethostbyname2 does not fill ->h_aliases field in the result AT ALL, and is iffy in general) getaddrinfo: remove superfluout indentation, fix incorrect one. remove one superfluous statement. getaddrinfo: runp->ifa_addr indeed can be NULL, don't dereference it ifaddrs.c: cosmetics, no code changes fix segv on clearenv(); unsetenv("foo"); [was deref'ing NULL], add a few missing ENOMEMs, some code shrinking setenv.c: further code shrink setenv.c: tiny code shrink smaller memcpy remove __libc_getdomainname alias. google says only we have it. remove __libc_fcntl[64] *: remove some __libc_XXX functions: __libc_accept __libc_close __libc_connect __libc_creat __libc_creat64 __libc_fsync __libc_lseek __libc_lseek64 __libc_msync __libc_nanosleep __libc_open __libc_open64 __libc_pause __libc_read __libc_readv __libc_recv __libc_recvfrom __libc_recvmsg __libc_send __libc_sendmsg __libc_sendto __libc_tcdrain __libc_wait __libc_waitpid __libc_write __libc_writev They were removed from glibc 1 May 2004: http://sources.redhat.com/ml/libc-hacker/2004-05/msg00001.html smaller brk() for i386.

(more of it remains in multiple copies of sigaction.c) i386/brk.c: gcc can't figure out how to use %ebx in PIC mode, help it. Code size is the same. *: document __USE_EXTERN_INLINES better; fix uclibc build if it is forcibly enabled string/generic/memcmp.c: remove some really paranoid guards for ancient compilers. none of other string/*.c files have them. Make it again possible to have compact and small stack usage on non-SSE capable processors. I'm doing it the second time. make all "XXXhidden_proto(" consistently not use a space before '(' Do not install libc-XXXX.h files in "make install". glibc does not have them, so should be safe. doc snippets about defines we provide and/or use features.h: add TODO (changing __OPTIMIZE_SIZE__ is a wrong thing to do) Remove the rest of "bounded pointers" scaffolding. gcc website says" "Bounds Checking Projects... This project has been abandoned" for four years at least. Add proposed plan of sanitizing sigaction to docs/* heed compiler warnings about checking non-defined variables in #if directives sigaction overhaul as described in docs/sigaction.txt Run tested on i386. remove some duplicates in bits/signum.h. No code changes. Remove __libc_posix_fadvise[64] alias. It existed on i386 and arm only, and google says only uclibc has it, no users at all. fix testing "gcc -mpreferred-stack-boundary=2" on x86_64 resolv: fix testcase failure test/regex/tst-regex2.c: fix testcase to compile with just "gcc <file>.c" memchr: smaller i386 version strrchr: smaller i386 version since gcc -Os hates us and does not inline string ops, implement inline versions of some of them. Enable only those which result roughly in the same code size as using out-or-line versions. fix for build failures resulting from "string ops for i386" change string/i386: smaller, and hopefully easier to read, strnlen(). remove one forgotten '##'. Heeds: warning: type defaults to 'int' in declaration of 'intfcntl' strncat: shorter version for i386, add small embedded test memchr: add small embedded test strnlen: make small embedded test easier to use strncmp: reformat assembly to make it readable, no code changes (verified with objdump) memmove: smaller one for i386, with added testing, and with added check for src == dest. run tested. strchr: a bit faster version for i386 (same code size) string/i386/strncpy: faster i386 version (same code size), testing code string/i386/*: formatiing and commentary tidying up string/i386/strncpy.c: fixlet for testing code string/i386/strchrnul.c: new function, adapted from strchr.c libc/string/i386/rawmemchr.c: i386 version, adapted from strlen() libc/string/i386/strlen.c: small optimization, same code size) Deal with a few data fields which may be made constant. libc/misc/locale/locale.c: remove one unneeded static data, rewrite one exceptionally unreadable loop.

Also alias drem to remainder. libm/e_lgamma_r.c: cosmetic whitespace fixes libm: remove scalbln implementation, it seems to be less correct than scalbn. instead, either alias scalbln to scalbn if int == long on this arch, or just call scalbn form scalbln. fix small goof in last commit: should use "long" function (scalbln) as a main one, not "int" one (scalbn). libm/e_scalb.c: remove unused #ifdef _SCALB_INT branches libm/s_ldexp.c: add TODO Get rid of the following annoying warnings on ppc: warning: nested extern declaration of '__illegally_sized_syscall_argN' From Stefan Assmann (sassmann AT suse.de) forgot to remove one #endif... ldso/ldso/dl-startup.c: make _dl_elf_main static; remove one dead variable. ldso/ldso/avr32/dl-startup.h: remove superfluous definition of START() macro. ldso/ldso/*/dl-startup.h: fix a typo in comment libc/signal/sigaction.c: s/!=/==/ simple optimizations and style fixes in dynamic loading replace yet another _dl_malloc + _dl_memset with _dl_zalloc utils/Makefile.in: de-obfuscate it a bit Rules.mak: use -Os, not -O2 __global_locale must be visible to users, move it outside of #ifdef _LIBC extra/scripts/relative_path.sh: fix it ldouble_wrappers.c: remove erroneous libm_hidden_def's *: remove __UCLIBC_CURLOCALE_DATA, __UCLIBC_CURLOCALE_DATA.x is always equivalent to __UCLIBC_CURLOCALE->x. remove typedef __uclibc_locale_t, it used only in a few places, it is lees confusing to use struct __uclibc_locale_struct everywhere. xlocale.h: hide __global_locale back under _LIBC, bug 53 is wrong in claiming it should be exported. Also hide under _LIBC: extern __locale_t __curlocale_var; extern __locale_t __curlocale(void); extern __locale_t __curlocale_set(__locale_t newloc); # define __UCLIBC_CURLOCALE # define __XL_NPP(N) # define __LOCALE_PARAM # define __LOCALE_ARG # define __LOCALE_PTR "make utils" now successfully makes utils for target Partially revent "make utils" fix.

Douglas Mencken (1): ldso: fix build error due to missing variable 'st' Ed W (2): inet: adjust handling of cacnonname in getaddrinfo wchar: Fix BOM emitting in iconv_open() Eric Andersen (2749): Add in a version number so apps can tell uclib is being used. -Erik More GPL vs LGPL fixes (sysdeps/getpagesize.c), and some header cleanups. -Erik Fix up the makefiles. malloc-simple/Makefile forgot to include realloc. test/Makefile used a hard coded absolute path (bad, bad, bad). -Erik Completely rearchitected the sysdeps directory. -Erik Many bugfixes, header cleanups, etc. Added abort and glob. It is getting closer... -Erik More header file cleanup. -Erik Lots and lots of cleanups. -Erik Hacked things so longjmp now works. -Erik Rework all the string handling. Make const stuff be constified. -Erik Some more major updates to further superate ucLibc from the kernel headers (the way it has been done in GNU libc). -Erik More stuff I forgot to commit. -Erik A few updates. -Erik Forgot this file. -Erik Temporarily revert to older working set of files. -Erik Revert to the old set of includes. -Erik Add needed include file -Erik Fixed dir/dirent -Erik Removed old noise. -Erik fix sys/vfs so it doesn't pull in kernel stuff. -Erik Add in a bunch of junk. Busybox now compiles (except for mkfs.minix and fsck.minix). Of course, it doesn't link yet due to missing functions, but hey... At least it is now easy to see what isn't working. :-) -Erik Updated to new scheme for handling syscalls. -Erik Make some of the rpc stuff compile -Erik Fix spelling More stuff. Down to only 43 missing functions before BusyBox will link. Fixed socket stuff so it doesn't pull in kernel headers and stubbed out fork and clone. A few other header file cleanups. -Erik Add in snprintf and vsnprintf -Erik Yet more updates. Getting closer.... -Erik Remove __restrict when not supported -Erik Repeat after me 100 times: I will always compile before I commit -Erik Fix up the Makefile for better portability -Erik Add in some more test suite stuff. -Erik More missing prototypes. Major facelift on the test area -- the beginnings of some real testing stuff so we can get this library into shape. -Erik Makefile sanity fix. -Erik Sanity fix. More sanity yet. This is making far too much sense. Fix all the makefiles. Clean up some warnings, cleanup some headers. -Erik Remember to remove libc.a on 'make clean' More makefile updates Major update to string handling. strcmp and friends were horribly broken. They now test out as working properly. -Erik Warning cleanup Dependancy fixup, and remove some obcolete files. Remove obsolete file. Fix dependancy. Dependancy update Remove obsolete files. Update dependancies. Update dependancies Dependancy update Add in support for shm/ipc. More cleanups Forgot to ignore this Update and simplification. Formatting update Formatting update New malloc routines. Bug ugly formatting update Forgot this Needed now. New misc tree that actually has misc stuff in it. Reorg unistd dir Test cleanup Finish reorganizing things. At least I think I've finished. Screwed up non-mmu support. #define was backwards. -Erik Makefile update Stupid makefile bug, Bypass problem with signals for the moment... More updates Update to assert behavior Update excludes Clean up after ourselves Ignore more junk Better syscall building mechanism More stuff Fix up ctype.h Naming fix Signal test. One test written and already found a bug. -Erik More updates. Implement strsignal. Add pwd_grp tests Strip all object files of all non global symbols and .note and .comment, saving a lot of space in the resultant binaries... -Erik ignore more stuff A smaller, kinder, gentler regexp implementation. Switch to doing syscalls in C. Makes things much more easily portable. Remove io Need this now. Link w libcc. Include real prototype for bcmp Try removing no-builtin Cleanup arch support First pass at arm arch support. Works on my netwinder... -Erik Revert Makefie changes. Updates (list_syscalls.sh was missing _syscall0 calls). Another bug fix. ioctl lacked a ; Fix dependancy problem Dependancy fix More reorg. A place for everything and everything in its place... Forgot a few things... Fix a few more screwups. Support even more syscalls. -Erik Try adding in a generic cross platform _start.c to make future porting less painful. -Erik A few more syscalls. Move syscalls to sysdeps/linux/common (since they are common). Remove _start.S since I now have a portable C version. Add some more stuff -- {get|set}mntent, getline, getdelim, etc. Add in arm specific bits. Fix it so it compiles again. Remove redundant clone file. Fix Makefile so archs build again. Remove some minor glibc'isms. Link vs libgcc to include needed stuff. Not needed -- apps simply need to link vs libgcc. Fix makefile bugs This had some nasty x86 asm inlines it. Throw them away. Add in a fork test. Fix select so it works. Ignore leftovers... Not needed. Seems to work fine without asm... Add in getprotobyname, getservicebyname, and related junk Fix up signal handling More random fixes and additions. _start.c is a failed experiment. Go back to using asm... Add in a platform specific _start Fix up stat so we translate from kernel stat to libc stat. Try to fix up a few little things with dir entry reading. busybox now compiles, and seems to basically work... :-) -Erik Oops. Fix up stat. Again. Header file cleanup More header file updates Fixup some PMTs First pass at fixing readdir by adding a getdents wrapper... Move config stuff to a file named "Config". Makes sense to me... getcwd did not include the alloc-space-as-needed-on-NULL-buffer feature which busybox needed. So I added it. Remove need for the bloated sysdep.h -- we don't need it, so axe it. Fix symbol problem. Add in arm support -- might even work... Need these includes, so add 'em. More cleanups. Fix things so tinylogin compiles. Fix a bug in getdelim -- patch from David Whedon <dwhedon(a)gordian.com>. Make spelling of uClibc be consistant. Fix doc blunder. Fix doc blunder Fix doc blunder. Fix up a few messes so it compiles cleanly again. Add in tmpnam() support from David Whedon <dwhedon(a)gordian.com>, rework include/stdio.h, and fix up the resultant damage. Remove environ from _USE_GNU wrapper. Fix it so files are not stripped when debugging (doh!). Fix up strip rules. With this fix in place, I can now find what is wrong with malloc... -Erik Doh!!! I am an idiot. I had broken malloc by disabling getpagesize(), and I didn't even do it for a good reason. Fixed, so malloc should work again... -Erik Bad Erik. Repeat after me: "I will always compile before I commit". -Erik Turn off debug noise Some cleanups from Manuel Novoa III <mnovoa3(a)bellsouth.net>, and a bit of extra cleanup in the test makefiles. Add in flock (though nobody should use it...) Oops -- this should not have debugging hardcoded... Fix a bug in memcmp -- don't terminate the compare on a NULL, keep comparing up to n bytes, till the are found to be either the same or differernt. Add in an additional test for memcmp suggested by Mathias Lewin <mln(a)sys.sigma.se> (I just checked in a fix for memcmp to make it pass). Some cleanups from W. Greathouse <wgreathouse(a)smva.com> (and a few of my own) Several updates from W. Greathouse A few cleanups. Fix fflush so it remembers to init stdio. Add yet another missing header file Handle fork and vfork on a per architecture basis... A number of updates from Manuel Novoa III. Things look good... Sync version number with Makefile This file violated policy and directly used kernel headers. This fixes it by using our own copy of the stuct in question. Just define __kernel_off_t ourselves... Move stuff out if pwd_gep that doesn't belong there (getpass, utmp stuff) Seems I forgot these... A bunch of updates, part from Manuel Novoa III (such as more long long support), and other updates by me (better cross platform, cross-compiler, etc, support. Now compiles with 2.0.x kernels for armnommu. Carefully tell folks when their Config is screwed up. Duh. This was so wrong. Oops. Extra #endif... Patch from James Graves <jgraves(a)deltamobile.com> to get m68k started. Should be just sysdeps/linux/m68k left to hack at this point... Oops. left strftime.c in twice. Make error msg even friendlier. A large update from Manuel Novoa III <mnovoa3(a)bellsouth.net>. When doing a 'make clean', clean all subdirs, not just the current arch. Makefile cleanups. For starters, OPTIMIZATION was missing... Ignore generated files. Cannot portably pass a short via va_args, since it will be internally converted to an int on many platforms. So make it be an int explicitly and call that good enough. -Erik Manuel Novoa III modified malloc.c and avlmacro.h to reduce code size by using functions instead on Inlining (size vas speed tradeoff). I ran the results through indent. Looking pretty good IMHO. Update makefile to match the new malloc code Clean test dir on 'make clean' Thanks to James Graves <jgraves(a)deltamobile.com>, we now have a first pass at getting m68k working. It may have some problems, but should now be fairly close. Patch from James Graves <jgraves(a)deltamobile.com> to better handle m68k. Also fixes 2 very important malloc bugs! Anyone using malloc (esp mmu-less) should update and recompile. -Erik "I will always compile before I commit." "I will always compile before I commit." "I will always compile before I commit." -Erik Makeheader files be more like GNU I've been working on fixing up the rpc crap. now it is only _mostly_ broken, a big improvement. Still doesn't compile... Make the implementation match the header file. Reduce dependancies -- don't use sysconf() internal to libc. Fix naming error. s/sigsetjmp/__sigsetjmp/g USe the name crt0.o, and cp it to $(TOPDIR)/libcrt0.o Use the name crt0.o, and cp it to $(TOPDIR)/libcrt0.o Use the right name. Remove generated files. Bring Makefile behavior into sync with other arches. init var to 0 to avoid warning Warn using $(WARNINGS) If they have an x86, but HAS_MMU is false, warn and sleep(10) since 99.999999999999999999% of all folks compiling on x86 have an MMU. Otherwise, folks will see that malloc mysteriously doesn't work... -Erik First pass at making this work with the new libcrt0.o location. Remove and ignore unwanted generated binaries Fix termios handling. Now synced with behavior of GNU libc. -Erik linux 2.0.x kernels have broken header files. It is silly to be so tightly coupled to kernel headers (since the 2.2 ones work with 2.0 as well), so I'm checking in include/net. Added common handling of errno. Facelist/cleanup for several syscalls. Added poll. Clean all subdirs on 'make clean' Symbol cleanup/bugfix. Add in needed global. Add poll, so this is now needed Add wrapper for old termio interface Remove the nonexistant __sigaction Add first pass shared lib support into Makefile. This could use some refinement... Ignore generated binaries. Add a Config usable by most stock x86 systems. Remove generated files. Makefile fixes Remove generated files Ignore generated files Oops. Forgot to check these in... Remove an extra "/" from the crt0 path Fix arm so it actually works. A little update to wait* and a minor syscall cleanup. Update the comments a wee bit. "I will always compile before I commit." "I will always compile before I commit." "I will always compile before I commit." -Erik Now works on StrongArm (using crt0.S) and arm7tdmi/uClinux with the arm-pic-elf compiler (using crt0pic.S). -Erik Minor comment update Reworked all test suite makefiles (man did they need it). Bring into line with proper sest suite behavior Add in NATIVE_ARCH Always use system libc, to facilitate bootstrapping new architectures. -Erik Oops. Should be LDFLAGS, not CFLAGS twice This is a silly update to the makefile to test the new script used when doing a cvs commit. I hope it works. -Erik This is a silly update to test my change to the script that emails folks after doing a commit. I hope it works. -Erik Don't trash regs r0-r2, fix thanks to Michiel Thuys <michiel.thuys(a)intersil.com>. Commit a pointless change to test more updates to the logging script. -Erik I hereby commit a sin. features.h is now going to _lie_ and claim that this is GNU libc. Too many pieces of code look for GNU libc version numbers. So uClibc is now going to lie and claim it is GNU libc. This makes, for example, networking apps work much better since /usr/include/linux/socket.h does the wrong thing otherwise. There are lots of other examples. -Erik Fix up the set of include files pulled into resolv.h Bring into sync with a fairly current glibc header file. -Erik Update networking includes. Make the __GLIBC__ define be conditional. Stub out gnu-versions.h -Erik Fix up the networking includes -Erik Update the build system a bit. -Erik Fix the worst of the damage so it actually compiles now (though, strictly speaking the entire pile of rpc dung is infect damage). Anyway, hopefully NFS using things may now be able to work... -Erik Try enabling rpc support by default now. With a bit of luck it might even work... -Erik Fix broken dependancies. -Erik Wierd. Whats _null_auth doing here? -Erik _void_void_null_func never returned. I noticed this yesterday in crt0.S and Michiel Thuys <michiel.thuys(a)intersil.com> noticed the same thing in crt0pic.S. -Erik Include ptrace support so debugging will hopefully work. -Erik Add in a silly test to check that argc, argv, and environ are working as expected... -Erik It turns out that vfork was completely broken. That was why it wouldn't run on my little arm7tdmi/uClinux boards, since without vfork working, nothing works on uClinux. It took me forever to find this, since other problems were hiding this one. Big, huge, sigh of relief. -Erik Doh! I forgot a #ifdef such that ptrace ended up in each and every syscall .o file. -Erik Remove times and all the foolishness surrounding it. There is a syscall that does this, so use that. -Erik Revert stdio to initializing itself. Not quite a pretty but that ensures that we don't blow up by using too much stack space, and simplifies the job of supporting new architectures, since they don't have to mess with calling foo init functions in crt0 and cleaning up the resulting damage. -Erik Implement getdtablesize(), which is used by the rpc crap. -Erik Try to automagically pick the correct dynamic linker. -Erik Silence warnings -- add func declaration. -Erik Add missing ffs, used by rpc crap. -Erik Add ffs func declaration -Erik Remove now irrelevant comment. Use __environ instead of the GNU extension environ. -Erik Add MAP_FAILED per spec -- patch from Michael Shmulevich <michaels(a)jungo.com> Use MAP_FAILED. I just changed "net" to "inet" to better follow the directory structure of libc5 and glibc. Fix the makefile accordingly. Folks will want to 'rm -rf net' to remove the old "net" directory. -Erik Add an SH port done by Jean-Yves Avenard of Hewlett-Packard - Embedded and Personal Systems. Thanks! -Erik Update to "malloc" so it will work on CPUs not supporting non-aligned words. malloc still only works for little-endian CPUs... Patch by Jean-Yves Avenard Patch from Jean-Yves Avenard to add missing siglongjmp entry and fix a bug in setjmp for SH div and ldiv are required for ISO 9899 -Erik Fix two bugs. First, gethostbyname was doing dns queries when given an IP address. Secondly, when doing reverse dns lookups, it was appending the domain, even if a domain was already attached. -Erik Let system dependant things override common things. This actually fixes things I believe. This is a touch cleaner, avoids using the comma operator. Sigh. Turn debugging back off. Forgot to increment i Update arm for the new way of entering main. BTW, I can now run things on arm as a shared library, using the glibc shared lib loader. :-) This evening I've been investigating why linking with the shared uClibc library was not working when booting busybox as init, even though it workes when run on my desktop system. I made boot floppy with just /dev, a few /etc entries, busybox dynamically linked vs uClibc, and /lib with shared uClibc in it. And just as several people have reported, it didn't work. strtok_r.c was not being compiled in, so fix that. Use LDFLAGS, don't always include -nostdlib... Patch from Jean-Yves Avenard to move the getopt globals to their own file, since at least on SH, weak variables with initial values (.data stuff) were not working. Moving these to their own file seems to be a good way to handle it. Fix up some long standing iterative symbol usage problem, noticed today by Michael Shmulevich, which was caused by the grafting in of GNU libc header files. -Erik stat and mknod cleanup, take two. Put all the needed junk into syscalls.c for clarity. -Erik I just grabbed the bits dir from glibc 2.1.3 on a sparc box to facilitate the sparc porting work being done by Mathew Bosworth. -Erik Add strnlen Reworked the password stuff to be reentrant. Group stuff is still needing to be reworked. -Erik Make alloca work using the compiler builtin -Erik Add in wordexp support (mostly stubbed out for now) since the busybox shell, lash, is about to start using wordexp. -Erik Hmm. Seems I left wordexp off. oops. Delete wordexp. There isn't much point in having this since so few apps use it, and it is just a stub anyways. Better to just skip it. Add index and rindex Fix the header file for index, rindex and similar Add strxfrm and strcoll Hah. It turned out that index and rindex were _already_ there and already implemented as wrapper funcs. And so just the header files were wrong. Anyway, axe the old index and rindex. -Erik Wow. I'm all full of stupid mistakes today. Fix strxfrm -Erik Add powerpc port done by David Schleef <ds(a)schleef.org> Add in a setjmp test from David Schleef Fix up breakage resulting from flipping the sense of some defines. Change from defining things to "0" in the disabled case to outright undefining them, lest code that does an "#ifdef FOO" get inadvertantly triggered. Remove now unneeded lines from Rules.mak which makes the command line smaller and avoids redundancy (since this stuff is now pulled in via features.h). -Erik Move yet more stuff into the uClibc_config.h file With the Official Declaration of coff being dead, we can forget about wrapper functions and just use weak symbols. -Erik Sync i386 up with _all_ the glibc 2.1.3 include/bits headers, since we will end up needing a few more of them anyways, and all the other arches have the full set anyways. -Erik Add a sneaky backwards compat hack from Michael Shmulevich Sync with glibc i386 bits. Add sigintr, from a patch by Michael Shmulevich Add in the sysvipc patch from Michael Shmulevich Debug should be off by default Move the dirent stuff. I suppose it is system dependant, but then it really should be grouped together too. And it needed to be grouped more then it needed to be in sysdeps/linux/common Add in alphasort (working fine) and scandir (just a stub for now). -Erik Seems most folks don't have /sbin in their path Add in the timezone global from time.h, from a patch by Jon Nelson <jnelson(a)boa.org> I think this fixes the dependancy problems. Manuel, can you double check that this is what you intended? -Erik Fix some strange formatting, so the compile looks prettier. Put regex back in Fix from Jon Nelson for error in timezone -Erik Stub out localeconv. Please look over this to check it is correct.... I started trying to read the glibc code -- but that code is far too messy to be read. So I just wrote a silly C app against glibc, set the locale to POSIX, then called localeconv(). I wrote this version of localeconv.c so it returns the same stuff. -Erik Add in random(), make rand use that under the hood. Fix the include file so folks know random is now there. It seems ARM 2.4.x kernels do not have iopl. Also add missing bits/sem.h for ARM so everything now compiles and runs. -Erik Fix a bug noted by David Beamonte <dbeamonte(a)intelnet.es>, so that we define "__linux__" in uClibc_config.h, not "__linux_". Add in daemon.c, now used by busybox. -Erik Accomodate mmuless systems. Add in delete_module -Erik Compile the compiler last Get the full set of module creating syscalls in place. -Erik Make a naming change to be consistent with other cross compiling tools. Set up a default lib dir off the root of the uClibc compile dir. This really needs more thought, but is good enough for now I think. Update the ignore file to match Fix include/errno.h to not use kernel header, and instead use bits/errno.h. This required we use _LIBC instead of __LIBC__ to be consistent with glibc. This had some sideffects in sys/syscalls.h. While fixing things, I made everything use __set_errno() for (eventual) thread support. -Erik Fix up more leftovers resultant from fixing _LIBC Update temp file handling and use a single function to do all the heavy lifting (most of the heavy lifting stolen from glibc, but reduced a bit). Add missing time() Posix 1003.13 POSIX_MULTI_PROCESS specifies that execle() should be there, so I just wrote it up. -Erik Remove all the __THROW macros Add missing alias siglongjmp = longjmp; -Erik Bring sh and i386 longjmp implementations into sync Add in a libcrypt implementation. About 8k. -Erik Remove the old crypt implementation getnetbyname.o, res_init.o and res_query.o were missing from the Makefile, patch thanks to John Hall <John.Hall(a)optionexist.co.uk> Nobody should be using the SYS_ syscall names. Use the __NR_<foo> names instead. -Erik Add missing header file for daemon.c, add missing functions into unistd.h. I still need to implement getlogin.c fpathconf.c, but they are required for IEEE Std. 1003.13-1998 POSIX_FILE_SYSTEM conformance and we don't have them yet. But we will very very soon. :-) -Erik Oops. I forgot the header file -Erik Update the ignore targets Add in a trivial getlogin implementation Stub out fpathconf() -- FIXME -Erik Use the real getnetbyname(), not the stub in resolv.c Only compile in daemon() if the target has an MMU. -Erik Initial checkin for ld.so. This is a combination of effort from Manuel Novoa III and me. I've been working on stripping out arch dependant stuff and replacing it with generic stuff whenever possible. -Erik Ignore generated stuff. Add a 'make install' target that works. -Erik Ok, seems this _must_ be compiled as PIC code. -Erik Revert my syscall changes. The _syscall# macros are not PIC friendly and don't work. Back to nasty asm... Always use __NR_<name>, not SYS_<name> -Erik Fix up compiler name Define where the shared lib loader now lives... -Erik Fix up the main makefile. Autobuild ld.so and install it when appropriate, Make sure that we list the shared lib loader as a required lib by explicitly linking against it. That way 'ldd' tells us what we need to know. -Erik These are needed for arm ld.so support (not at all working yet...) -Erik Silence a warning Avoid a chicken-and-the-egg problem. Use $(LD) to compile the libdl library, not $(CC). -Erik Disable an ugly bug-workaround for ancient versions of gcc. -Erik Make sure 'make install' creates needed dirs. Be more strict with the glibc style malloc implementation. Return NULL when folks do a malloc(0) using malloc-930716. Be more strict with the malloc implementation. Return NULL when folks do a malloc(0) using malloc-simple. -Erik As pointed out by Michiel Thuys <michiel.thuys(a)intersil.com>, this was checking sizeof which was pure bloat and in many cases wrong. -Erik Move libdl and udate build method a bit -Erik Update ignore target Be really sneaky and use GNU ld special stuff so that whenever folks use the unsafe gets, they will get a warning from the linker. muahahaha. This method will soon be applied to fork() w/o an mmu etc... -Erik Revert my ill-advised change to force the shared lib loader to always be linked. Just make libc.so link vs the shared lib loader and everything works fine. Duh. Thanks to Michael Shmulevich <michaels(a)jungo.com> for clueing me in. -Erik Fix up default .so number. This should avoid conflicts with libc5 libraries... Some minor makefile fixups Oops. I forgot to check this in last night, so if anybody built uClibc during the last 18 hours it would have failed. Sorry about that... -Erik Keep major number in sync with the toplevel makefile Be more careful about not hard coding names. Missed these Ok, this should finish things up -Erik Don't hard-code the major number oops again! I forgot to pull in the arch specific stuff, and forgot to update those makefiles. -Erik Ignore generated binary Ignore strerror Just use 'ls -l' since ls -sh lacks sufficient granularity A few more compilation updates More trivial changes. Ignore stuff Patch from Tom Walsh <tom(a)cyberiansoftware.com> to fix a thinko on my patch. As noted by Michiel Thuys <michiel.thuys(a)intersil.com>, the weak alias for srand was in the wrong file, causing rand.o to be needlessly included in some cases. Yet another large update to ld.so. In this iteration I finally got the C based syscalls working, which greatly simplifies what it takes to get new architectures running. -Erik I messed up the comment Eliminate the useless _dl_interpreter_exit function For m68k I forgot a needed #undef Add in missing ARM support. I really need to port this whole thing to use a modern version of elf.h from glibc. -Erik Get rid of the a.out header file Fix up a comment Sanitize the calling of _dl_linux_resolver so it can be read by mere mortals, and so it says what it means. Ick this stuff was nasty. -Erik Yet another major rework. This time around, rework it to no longer use linux kernel header files. -Erik I forgot to check this in. -Erik Another cleanup. Never pass addresses as an 'int' -Erik Some more updates and explanation Avoid needing to distinguis between the install dir and the build dir. Use both automagically when compiling. -Erik Some more minor updates. Add in some debug stuff, and a way to print out addresses _early_ on in the process. Describe what this routine is supposed to do so we can port it to other achitectures. Dont segfault when folks run ld-uclibc as an executable. This is kindof neat. With this update, you can now simply set your PATH and things will now simply compile vs uClibc. Or you can add INSTALL_DIR/usr/bin to your path and use it as a cross compiler. Either way, it works now. -Erik Initial sparc port, thanks to Mathew Bosworth <mbosworth(a)metaflow.com>, who sent this to me a month ago and I forgot to check it in. Oops. Better late then never. -Erik This patch allows powerpc to compile again. It also checks if we are compiling for an arch for which uClibc has an ld.so or not, and otherwise sets things up to use the system ld.so. -Erik Another update to make sure things work properly on x86 now. Fixup ppc to powerpc Add in inet_ntop() and inet_pton() -- ported from glibc 2.2.3 by Cory Visi <merlin(a)phear.lwz.org> Change FILENAME_MAX to be only 255. Max filename on ext2 is 255, so there is no reason to allocate 4k. Change working of execvep.c per patch from Matthias Kilian <kili(a)outback.escape.de> so that there is not a fixed 127 byte buffer. Too easy to overflow... -Erik Put in but leave commented the DL_DEBUG define Use the symbolic name, don't hard code. Looks like I forgot to commit this. Some very minor cleanups Make sure types are pulled in Add in a qsort, alphasort, scandir test from Jon Nelson, jnelson(a)securepipe.com A patch from Jon Nelson <jnelson(a)securepipe.com> to make scandir sort things as it is supposed to do. Turns out alphasort was totally broken. This fixed one works. -Erik Add in libutil, based on Cory Visi's variant of Michael Shmulevich's libutil port. I have reworked the code quite a bit so that the stuff that is supposed to be in libc is in libc, and I added a bunch of missing stuff so the libutil interface matches that of glibc's libutil. The only caveat is that libutil/login.c is currently a stub. -Erik Yipe. This was still pulling in kernel headers. -Erik compile up libutil By default, leave out the RPC junk (it adds over 30k). Add in a compile time option to include it if NFS support is wanted (does anyone every use this for anything else these days?) -Erik Add in an older libc5 glob implementation, which is a bit thinner. -Erik ignore generated stuff Don't hard code path to TARGET_CC uClibc now has a math library. muahahahaha! -Erik Add in _dl_strrchr minor formatting cleanups Ignore generated file Fix up naming of ld.so so every uses the same define. The top level was using one name and the ld.so-1 dir was using another (they happened to be the same). Fix that. -Erik Check if ld.so is included in the NEEDED list. If so, do not _again_ try to fix up its symbols since they are already fixed up, thank-you very much. Seems a few apps need this one... These are needed for ash-0.3.8 Oops. Forgot the makefile updates Fix broken resources.h Fix 'make clean' so it clean the rpc dir Fix 'make clean' target Fix up the 'make clean' target A patch from Matthias Kilian <kili(a)outback.escape.de> to fix -DDEBUG_MALLOC so that it works for realloc too. -Erik Fix up the 'make clean' target Fix the 'make clean' target Bring powerpc back into line so it compiles again. Fix a couple silly bugs in this test Change 'crypt' to 'libcrypt' Rework where libraries get installed to. Now thew will be compiled and dropped into a uClibc/lib dir when compiling, which will make life a bit easier when installing and cleaning up. Preface uClibc with 'lib' so ldconfig will recognize it as a library. Make all libraries have the uClibc version number attached, making upgrades possible by using the traditional symlink to the .so name plan. -Erik Ok, this should finish off my massive ro-organization. The source tree is less messy now (which helps), all libraries are placed into uClibc/lib when compiling, all libraries now use a consistant mechanism for being built, all libraries use a consistant naming scheme where the lib name includes the uClibc version number, which makes ldconfig happy and willing to work with us. -Erik Add missing header file for arm I'd broken powerpc crt0.o installation This file was missing on arm Add in a libc.so link as well These seem to be missing also Should not call make on ldso/libdl Fix up a few little problems Oops. I left in some debugging noise. Also some minor formatting updates. Oops again. We do want to print this info, but only when _dl_trace_loaded_objects is true (i.e. when doing an 'ldd') -Erik Sigpause was broken. Now it is fixed. -Erik Move the default ptrace.c to common, but let arches override it (such as m68k which has some asm in its version). -Erik Add in tempnam() Patch from David McCullough <davidm(a)lineo.com> -- do not try to build ldso when we don't support shared libraries... Fix up some problems noted by August Hoerandl <ahoerandl(a)gmx.at> when cross compiling with shared lib support, there were spots where the native 'ld' was mistakenly being called. I wasn't building the libdl shared lib anymore. Make each lib install a libfoo.so symlink as well as a libfoo.so.0 link, since gcc is currently only looking for files ending in .so. wierd. -Erik Wrap getline() inside #ifdef __USE_GNU Patch from Andreas Neuhaus <andy(a)fasta.fh-dortmund.de> gcc was looking for crt0 in the wrong dir. Oops! Stub out libresolv for now. Some apps try to link with it (though almost always erroneously as a result of configure scripts that were poorly done). This will let such apps compile... -Erik rewrite to accomodate devfs One last structural change. Install header files to INSTALLDIR/usr/include so we now parallel the behavior of the standard tools. Update for the SH port from Jean-Yves Avenard <jean-yves_avenard(a)hp.com> Cleanup the math.h header file. It was broken when enabling doubles but disabling long doubles. -Erik We need the definition of HUGE_VAL fpr some apps. Include it. -Erik Add in missing capset and capget syscalls. Stub out syscalls when missing rather then just omitting them... -Erik Add in some more GNU compatible locale stuff. I only implement the C locale of course. util-linux needs this stuff to compile... Enable mlock and friends if __UCLIBC_HAS_MMU__ is defined. util-linux needs this to compile. Add in message queue support, based on work from <tapu(a)371.net>. This is required to compile util-linux Fix regex support to be compatible with 4.2 BSD regex library. This is the last bit that was needed to get util-linux to compile. Make powerpc compile. Needs this header... Don't try to run ldconfig unless it exists These are needed for arm to compile Comment out broken test Sometimes (often) the kernel will return things other then -1. Deal with it. -Erik Define "NM = $(CROSS)nm" and use $NM and $AR in get-needed-libgcc-objects.sh in all cases. Remove the now obsolete "headers" target. Fix call to get-needed-libgcc-objects.sh to we define NM and AR properly. warn folks that libresolv is a stub Cleanup some stupid warnings Add in an initial TODO list. Please add stuff as needed (and feel free to work on items in this list as well). -Erik decouple this from strchr oops. Put the locale stuff back how it was till we can get a proper implementation that doesn't suck so badly. -Erik Teach the ldso stuff to use the proper elf.h header file, not a local copy. -Erik Add a new 'readelf' util I wrote this weekend. -Erik Update the TODO file Add in a test for outb (that currently fails) Get rid of the unused LDSO_VERSION Default to malloc-930716 for x86 Default to testing shared libs. Silence a few warnings. Some socket cleanups Cleanup the toploevel makefile handing of shared libs. Add weak_alias define, and set things up so nasty old coff toolchains can now compile things and should actually work again. -Erik Make sure these use the local sysdep.h header file Some sparc updates from Stanley <ngstanley(a)cwc.nus.edu.sg> Use sys/mman.h not asm/mman.h -- we don't want kernel headers... -Erik A few new todo items Default to something like a strongArm, (i.e. has an MMU) Don't create a fake readelf app. We are creating a real one now. -Erik Fix a really stupid bug with ttyname, thanks to a patch from Stefan Soucek <ssoucek(a)coactive.com> Yet more ldso cleanups. Be more discriminating about when using inlines and when using real functions. Make things be more portable by providing a default C routine to locate the got. -Erik Some silly grammar stuff Make all the uClibc tests use the --uclibc-use-build-dir flag Be consistant for all the client code, and use TARGET_CC with --uclibc-use-build-dir Add in (stub out really) __libc_current_sigrtmin, and __libc_current_sigrtmax so current versions of ash will compile. -Erik I am very proud of myself. I managed to write a working _start for x86 entirely in C -- no asm required. muahahahaha! -Erik Make strrchr not call other string functions. Hopefully speeding it a bit. Now that our compiler wrapper is up to it, we can now use TARGET_CC to compile ldso, simplifying the process of passing in special CFLAGS and such (and simplifying the build in general since we no longer need to go directly to LD to link things). -Erik Make some nice SEND_ADDRESS_STDERR and SEND_NUMBER_STDERR macros that operate inline, to help when debugging ldso (i.e. before we can do things like function calls). -Erik Note missing struct _res in resolv.h These are needed for powerpc to compile A few build updates I went nuts and wrote a generic rint implementation. I think it is correct per the man page and a little testing seems to show it works. -Erik This commit finishes adding support for the old m68k-coff toolchains by working around a missing header file in the compiler shipped with the uCsimm and uCdimm. This should make the folk in Toronto happy, since now they can use the latest CVS version of uClibc. -Erik This was violating policy and using a kernel header file... -Erik Add in "HAVE_SHARED" so shared libs build or not as needed -Erik Patch from Shane Nay, who noticed that these were not properly labeling functions as such, thereby hosing the shared lib loader. This adds in support for PIC on x86. Unfortunately, this will break all arches till they add in an libc/sysdeps/linux/<arch>/bits/syscalls.h file. Sorry about there, there was no other way... -Erik Make PIC a config option Add in missing syscalls.h for powerpc Looks like we lost clearing errno Step one in a process to ween ourselves off of using asm/unistd.h. This will break the build for a bit. -Erik Don't include asm/unistd.h Don't even threaten to include asm/* stuff Stub out an initial version. Manuel will be writing some code to autogenerate this stuff... Cleanup and don't require LIBC to be defined for the syscall numbers. Cleanup to not use kernel headers at all. -Erik Replace the crypt implementation with one based on crypt(3) from minix, fixing a licensing problem with the previous version. Manuel did the initial port, and I fixed it up to be reentrant. I hope I didn't break anything... -Erik Oops. I forgot to check this in... -Erik I missed an item when reentrantifying des.c, reuse a smaller field for md5.c -Erik Add a dlopen test Add syscalls.h for ARM Fix a silly typo Just take whatever the kernel headers gave us, spaces and all. This is to accomodate arm, where rmk has made the syscall numbers be very very strangely setup, -Erik Autogen include/bits/syscall.h for ARM -Erik Force our child libs to link vs libc Allow the shared lib loader to fallback on the builddir if everything else fails. Let <arch>-uclibc-gcc --uclibc-use-build-dir set the shared lib loader to the one in the builddir's path. -Erik Scrub up the tests a bit, and force everybody to use the build dir, so nothing need be installed... -Erik ignore generated stuff Oops. Scrub a couple of ints Merge arm support into the mainstream. This change is pretty minor, just carefully memset 0 strings before using them, and also referencs strings via the GOT for ARM as well. -Erik Merge the arm port into the main tree. The final version (the one that actually works) is the most excellent work of Shane Nay <shane(a)minirl.com>, who took what I had been doing and fixed it. Finish up merging the arm port into the main tree. Renamed as extra/Configs/Config.i386 Fix missing libresolv.so Note that ldd needs a rewrite forkpty.c uses fork(), and so must be disabled when HAS_MMU=false -Erik Don't change options on based on path -- use command line options or ENV variables only. The current behavior violates the principle of least surprise... -Erik Note missing shadow support Fix strxfrm, which was broken (thanks to Shaya Potter <spotter(a)us.ibm.com> for noticing, and cleanup a warning. -Erik This config seems to be basically correct for arm uClinux systems. -Erik Workaround an old m68k-coff compiler problem A patch from Michal Moskal <malekith(a)pld.org.pl> to include partial IPV6 support. This adds things like gethostbyname2(). Off by defaut, of course, Fix the code for finding the interpreter, which was I had totally screwed up the first time... -Erik Rewrite of ldd so it works as expected, and does not invoke the shared lib loader at all. This will allow us to throw out the support code for that from ld-linux.so.0 -Erik ldd rewrite is done Seems weak_alias wasn't working as expected... Add missing in_addr_t Use uClibc's ldd, not the system one which is probably broken anyways. This ensures correct answers, and prevents all the annoying segfaults from the system ldd. -Erik This commit merges David Schleef's updates to the build system, which a few tiny fixups here and there from me. Seems to work just fine and will hopefully be a bit better behaved. -Erik This takes about 6k off the size of the x86 shared lib loader... -Erik Scrub up a few things I forgot. Add a few more cleanups. -Erik use ln -fs Some cleanups needed for things to compile and work as expected with the new build system... -Erik We already have tar.h, so might as well include cpio.h as well... Forgot this... Oops. USE_CACHE was disabled and didn't compile when enabled since I'd forgotten a one liner... -Erik Fix missing function when USE_CACHE is enabled -Erik Turn off USE_CACHE by default (so ldconfig, by default, isn't needed). Fix a stupid typo in dlib.c where I had several weak symbols set up backwards, breaking libdl (dlopen and friends), -Erik Elimintate spurious trailing / search_for_named_library forgot to wipe the target string, so each time around the loop it was getting bigger... If /etc/ld.so.preload was size 0, the shared lib loader would choke and die. Test for non-zero size as well, -Erik Try search for the shared lib interpreter. Eliminate all double "//"s from the output -Erik This syncs things up with my local tree. Mainly changes installer issues, and syns things (as far as I am willing) with Dave Schleef's tree. We may need to go another round or so, but we do seem to be converging... Fix behavior when installing the devel env, since somewhere along the line this got messed up... Update the build system, yet again. I hope this is the last time... Here is the basic theory of operation: SHARED_LIB_LOADER_PATH/ <The location where the shared lib loader will be installed and where the compiler will cause apps to look for it.> DEVEL_PREFIX/ bin/ <contains gcc, ld, etc for setting PATH=$DEVEL_PREFIX/bin:$PATH> lib/ <contains all runtime and static libs> include/ <Where all the header files go> SYSTEM_DEVEL_PREFIX/ usr/bin/ <contains arch-uclibc-gcc, arch-uclibc-ld, etc that might be installed by a .deb or .rpm into /usr/bin, but can happily live under DEVEL_PREFIX> PREFIX This is prepended during 'make install's allowing you to shift things to be installed under some alternate location (such as when building a .deb) -Erik Don't blow away existing files when trying to install a ldso symlink... Oops. Symlink args were backwards... Begin removing some unnecessary inlining, and fix naming of _dl_fprintf which should really be _dl_dprintf -Erik Fix the library searching routine so it is way simpler, and so it matches the routine in ldd.c Sync up ldd behavior I rewrote strcat without any function calls. I just wrote a stpncpy() since someone wanted it Use malloc on arm (since I've never bothered to write sbrk) Add in TARGET_PREFIX, which was still used in a few spots (and appropriately so). Leave this hidden and set to a sane default since nobody should really need to change it... Fix SYSTEM_DEVEL_PREFIX to allow install of the <arch>-uclibc- spoofer toolchain to any arbitrary directory... Add in a make release target A few more (final?) cleanups for the installer behavior. I now think things are working perfectly (perhaps I shouln't think so much) Fix the "install_target" target to install to $(PREFIX)$(TARGET_PREFIX) use some #defines internal to the ctype functions to eliminate them calling other tiny ctype functions. Now all ctype funcs will end up with no extern references, which ends up shrinking both the uClibc shared lib and shrinking client code. -Erik Proper support for tests spannint multiple .o files -Erik Put a bandaid on getpgrp behavior powerpc doesn't have sbrk yet, so use "malloc", not "malloc-930716" Don't use --uclibc-use-build-dir for the tests unless BUILD_UCLIBC_LDSO=true Fix a stupid bug causing the ld-uClibc entry to be lost. Fix a silly bug with the header file Fix problem with possible redundant entries. Add byteswap.h, per glibc Add missing shadow.h atoi, atol, atoll, and atof are supposed to be functions, not macros. -Erik Get rid of non standard macros for things that are functions Add the __fopen prototype, since I pulled it from stdio.h Use "stdin", "stdout", and "stderr", not "_stdin", "_stdout", and "_stderr", since this is what gcc and libgcc expect... -Erik Make gdb/gcc/binutils happy elide some debug noise Add "__write" as a weak alias for "write" This will hopefully make global constructors and destructors work Fix goofy formatting Minor update Wrap up some long long stuff in __UCLIBC_HAS_LONG_LONG__ "Kim B. Heino" <Kim.Heino(a)bluegiga.com> reports Preevaluate some stuff so it only gets run once, speeding the compile Patch from Andrew Ip <aip(a)cwlinux.com> to add ftime, allowing openssl to be built. Patch from John Tyner <jtyner(a)cs.ucr.edu> to avoid redefined symbols by piping results through uniq Add lockf Recurse into 'file' Oops Add in a simple vfork test Fix the vfork test so it actually works this time. -Erik Rev all the header files to sync things with glibc 2.2.4 Update to accomodate the header file changes Finish syncing up arm Scrub up a few test things Add in missing file Optimize for size, and disable expensive inlining Gut this file, and quit referrng to _IO_* junk Silence stupid warnings caused by bad kernel network includes Silence a silly warning re-enable ntohl and friends Add inb, outb and friends, Be more careful about not redefining stuf Duh. Make iopl and ioperm work Sigh. Erik mucks it up again... Add in gcvt() Fix a stupid typo... Fix prototype Minor cleanup Fix nasty behavior difference from glibc -- also fixes getline() -Erik Turn off optimization when debugging Add in some math lib tests termcap.h is supposed to be part of ncurses, and has no place in the C library includes. Cleanup brk/sbrk Silly little changes Minor cleanups Patch from David McCullough <davidm(a)lineo.com>: Yet more minor cleanups Wohoo! David McCullough found the bug! His comments follow: Minor update Patch from Miles Bader <miles(a)lsi.nec.co.jp> to support the v850. He sent this patch to me a month ago, but I forgot to apply it... Add strndup, written by Stefan Soucek <ssoucek(a)coactive.com> Add missing values.h A small patch from Erwin Authried <eauth(a)softsys.co.at> *) changed ARM crt0.S / crt0pic.S selection -- depends on DOPIC now. *) Minor tweek to syscall definitions Beef up the fork test, checking for proper SIGCHLD behavior Erwin Authried <eauth(a)softsys.co.at> noticed that _XOPEN_SOURCE is supposed to be a number Turn off program_invocation_name and friend Revert global old mmap usage, and do it per arch Oops. I merged things backwards. Lets try that again... Geez, I really screwed that one up. Lets try that one again... Revert mmap to where it was in rev 1.41 of this file, -Erik Fix comment This commit makes large file support actually work (when enabled in the config file). I've tested this and it works for me. -Erik In theory, this adds readdir64 and friends. Dunno if they work yet or not.... -Erik This header file was broken, breaking signal handling on ARM. This update fixes it... -Erik Bring these into line with glibc 2.2.4 Fix up sig handling so it is more in sync with glibc behavior These are now obsolete Oops. Forgot this one.... Disable fast search by default (doesn't work on coda for example) Patch from Jari Korva <jari.korva(a)vtt.fi> to fix a memory leak in dns_lookup. Add statfs64 Patch from Jari Korva <jpkorva(a)iki.fi> I found some support in uClibc for IPv6 but I needed some more... Enclosed is the patch containing following modifications: A couple of TODO items Add missing sched.h Fix the clone syscall so it actually works. Initial first (lame) pass at making a pthreads library. This works for me when linking staticly on x86. Sync up m68k headers Sync up mipsel headers Turn off dtype Make it obvious that dtype is disabled Sync up sparc headers Scrub up some lingering problems preventing readdir64 from working and creating several *64 problems, particualrly when client apps used -D_FILE_OFFSET_BITS=64 -D__USE_FILE_OFFSET64. All better now. -Erik Oops. Forgot these I fixed readdir64 This is a .c file Fix comments. Attempt at c++ global constructor support. Silly me. I left in a define which caused statfs64 to recursively call itself. Another todo item Add an initial clone from glibc. Needs fixing. Fix default install dirs Be more careful able not shadowing with var names Can't use CLK_TCK in here since /usr/include/bits/time.h now defines that as __sysconf(_SC_CLK_TCK) causing infinite recursion. -Erik Fix up pathconf and friend so that test suits can work A few symbols needed for testing Oops. Lets try that again. pathconf can't use fpathconf or it will block opening FIFOs Add missing ctermid. Also add putc and getc (in case they get undefined which is a valid thing to do) -Erik Cleanup abort() so it behaves itself a bit better Add acct syscall. Fix sigsuspend which was totally broken (it needed a wrapper) Finish off the getc putc adjustment Fix support for sysv style signals Adjust naming for __FORCE_GLIBC__ to __FORCE_GLIBC and add support for __FORCE_NOGLIBC per Brian Stafford <brian.stafford(a)office-logic.com> Seems we were lacking an acos() implementation Totally rework the math library, this time based on the MacOs X math library (which is itself based on the math lib from FreeBSD). -Erik Default to building C89 math stuff only. Cleanup some warnings. -Erik Adjust configs for updated math lib Finish ajusting math lib options. Close out a couple of todo items. Add this so madplay will properly configure itself using oss as a default output device. -Erik I just spent a bit of time writing up a FAQ... -Erik Move powerpc specific optimizations (courtesy of apple) to powerpc subdir. Put together a theoretical framework for adding arch specific optimizations. Havn't tried this yet but it looks correct... -Erik Oops Fix path problem, Fix naming so things will actually work -Erik Silly us. Don't try to free alloca'd memory. -Erik Work around broken m68k kernel headers... Grumble. Oops Wrap uClinux specific stuff, so this will run on macs and such that have an MMU -Erik Much faster version of 'make install' -- it was doing one fork per header file... Ugh. -Erik Oops... Use consistant paths Move the FAQ. Add a docs dir. Add in a report on thread support. -Erik Sync regex with glibc 2.2.4. I need to add an option to select a minamalist replacement. Coming soon... -Erik My adjusted 'make install' was missing include/linux subdirs. Try just using 'cp -a' and see if anyone complains and makes me use tar or something. Add include/sys/reg.h to make gdbserver happy Always use --uclibc-use-build-dir Add support for mmu-full m68k systems, such as oldworld macs. -Erik Update TODO list a bit patch from Jari Korva <jpkorva(a)iki.fi>: Add basename and dirname. Write memrchr. -Erik Use the asm version by default on x86. Tag _start as a function. Update my email address. I am no longer andersen(a)lineo.com Oops. I accidentally commited some experimental test code (which was broken) yesterday. Revert that bit. -Erik Steven Carr noticed that uClibc's inet_aton() is stricter then in glibc, since no trailing blanks was permitted, such that inet_aton("192.168.1.1 ",&value); would work with glibc, and fail with uClibc. This brings uClibc's inet_aton() behavior into sync with glibc's behavior. -Erik Use tar instead of cp -LR for make install, since older GNU cp (i.e. RedHat 6.2) don't support -LR -Erik Fixup autogeneration of bits/syscalls.h Ignore tmp dir Add the website into CVS Update the docs and website Forgot this Fix snapshot link Oops. Revert debugging defines Miles Bader <miles(a)lsi.nec.co.jp> noted that I'd broken setting OPTIMIZATION from the Config file. Revert that. -Erik A very large patch from Miles Bader <miles(a)lsi.nec.co.jp> to bring v850 back into working condition. Thanks Miles! -Erik Update some URLs Bump version number to 0.98 -Erik Support older link name update website for release Text update Grammar Sigh. More grammar fixes More scrubbing Add udhcp More Updates. Add in the missing get_kernel_syms syscall Remove erroneous allow-shlib-undefined Change 'cd <foo> ; bar' to 'cd <foo> && bar' for proper error checking Change all 'cd <foo>; bar' constructs to 'cd <foo> && bar' for proper error checking -Erik Support arch specific optimizations (examples shown for x86 and ARM). Autodetect target architecture by asking the compiler. -Erik Add a test for a sigchld bug Cleaned up test that doesn't need manual intervention. -Erik New and improved! Silly spelling error Turn off the useless personality crap Fix usleep to work correctly. Fix sleep behavior in the presence of SIGCHLD. -Erik Take the shorcut version, which is good enough for nearly all normal usage. -Erik Once again, rework the signal handling to be even more correct. We no longer segfault when running test/signal/sigchld.c, which exposed a bit of a rats nest. The problem ended up being a erroneous syscall defination, but in the process of finding that out, I scrubbed things up nicely and adapted things to use the rt_ signals if they are available. This now passes all the signal tests. -Erik Sync SH header files with glibc 2.2.4, so it can actually have a chance (at least in theory) of working. -Erik Oops. Disable threading. -Erik Fix a few things I'd missed when using old (2.0.x) kernels. -Erik Patch to add rcmd support, from Stefan Soucek, which I'd long ago forgotten. Oops. Needed some minor scrubbing for bitrot, -Erik Cope with all variants of 'gcc -dumpmachine' output Fixes from M. R. Brown <mrbrown(a)0xd6.org> to fixup some little compile nits with the SH architecture, and support SH4, Enable several more syscalls. Oops. I'd accidentally enabled a #define for __NR_get_kernel_syms so turn that back off -Erik. Make getopt act the same regardless whether the app was staticly linked or dynamicly linked. Obeys the principle of least surprise. -Erik Add missing inttypes.h Support statvfs and statfs. Added getmntent_r (and made it use strtok_r instead of strtok), taught getmntent to use getmntent_r. -Erik Fix formatting. Stub out pthread_join and pthread_exit for now. -Erik Fix stupid typing problems Support tmpfile64 (just a weak for tmpfile) -Erik Use public interface, not a glibc style private one -Erik Fix stpcpy function declaration Mahe 'make clean' remove generated bits/syscall.h, as noted by "Kim B. Heino" <Kim.Heino(a)bluegiga.com> -Erik Scrub malloc handling Remove "-Wl,--no-undefined" Fix duplicate of timezone Be more carefull about erroring out of shell fragments. Try to enable -falign-functions if avilable. Fixup v850 architecture autodetection, from Miles Bader <miles(a)lsi.nec.co.jp> Patch from Stefan Soucek <ssoucek(a)coactive.com> to remove alloca (when non-reentrant) since alloca can blow the stack pretty easily on mmu-less. Patch from Michael E Brown <mebrown(a)michaels-house.net> to support setting DEVEL_PREFIX and BUILD_DIR at runtime instead of having to recompile the wrapper. Minor changes by me. Don't show shell fragments Fixup comments regarding large file support (it works these days) -Erik Rework termios wrapping code to try and do the right thing. -Erik Allow people to exclude regex code, since it is huge (27k) Fixup broken termios stuff. No, really this time. -Erik Implement mempcpy Doh! I broke getmntent when I added getmntent_r! This fixes it. -Erik Recommend making symlinks, not copying the config file. -Erik Build a native uClibc ldd Ignore native ldd Allow people to override the TARGET_ARCH setting Eliminate C++ style comments Scrub the way libraries are linked. Use ld, not gcc, to avoid chicken-and-egg problems when building gcc toolchains. -Erik Fix indenting Cleanup makfile, use ld to avoid chicken-and-egg problems when building gcc/g++. -Erik Failed to call sort before calling uniq in several spots, thereby causing ld to choke during the gcc build. -Erik glibc test apps failed to be static when told to be Build glibc test apps static when told to. Make tiny live up to its name. Don't use target strip on native binary Rework naming for shared lib loader to avoid potential nameing conflicts with std header files. -Erik Remove old named file. Fix headers on updated one. Remove the now obsolete d-link tree. Update things to cope with the new naming -Erik Oops. We lost -FPIC in the shuffle... -Erik More build system cleanups... Oops. typo. Sigh. Typod it again We don't need an ARCH_CFLAGS2, just fixed the ordering on ARCH_CFLAGS Make libc depend on ldso Depend upon libc Both _dl_simple_ltoa and _dl_simple_ltoahex use buffers of size 21, but we were feeding them strings that were just 13 bytes long... Thanks to spudmonkey(a)racsa.co.cr for noticing! -Erik Enable fdatasync Patch from Brian Stafford <brian(a)stafford.uklinux.net> to fixup support for Unix98 PTYs, and optionally exclude the older junk. Hide all reference to wchar_t so configure won't get confused -Erik Tell ld explicitly when stuff is supposed to by dynamically linked -Erik Oops. I forgot to add -Bdynamic to this one. -Erik Clearify error message Enable fcntl64, and fix fcntl when large fils is enabled. Don't waste space warning about tempnam() Allow apps to use varargs.h (not that they should) Make sbrk common, add arm/brk.c, cleanup leftover damage oops Fixup build a bit. Be sneaky and include everything into a single .c file, making stuff be even smaller. Fix up all non-x86 arches to cope with the latest ldso update -Erik Miles Bader <miles(a)lsi.nec.co.jp> noticed that `make install' tries to build ldso stuff on non-shared-library systems. And Matthew Bloch <mattbee(a)soup-kitchen.net> noticed that we need to create some dirs before installing some stuff, so fix that as well. -Erik Fix the bug where binaries built with older toolchains would segfault. Turns out that 'ld -nostdlib' was the culprit. Who wouldof thought... -Erik Updates to the v850 architecture from Miles Bader <miles(a)gnu.org> Create a changelog vs the 0.9.8 release so people can track exactly what has changed... Minor touchups Go back to using ld, now that I've found the real problem... Make it so powerpc can work despite lacking brk(). Force DOPIC be true when HAVE_SHARED is true. Don't define -D__PIC when DOPIC is true, since the compiler does that for use when -fPIC is set. Some minor formatting cleanup. -Erik Default to using malloc-930716 on ARM systems, since it is about an order of magnitude faster. Doh! I'd included sbrk.o twice... Add in setfsuid() and setfsgid() so lpr-0.72 can compile. -Erik Add missing sys/fsuid.h Fixup setjmp implementation so it actaully works as expected -Erik Fixup util build Fixup xfree86 entry Fix spelling error For now, don't let googlebot and friends spider the cvsweb stuff, since my little DSL line can't deal with the load. I'll reenable this in a few days when I get things colocated. -Erik make sure all utilities will build even with older toolchains by using our own local elf.h header rather than the system one. -Erik Fix makefile so it actually works when cross compiling -Erik Fixup setjmp and longjmp so they behave themselves properly now on both x86 and arm... -Erik Don't complain about _GLOBAL_OFFSET_TABLE_ Fix/simplify longjmp. Fix toplevel mips settings Don't assume uid=gid Be ever so pedantic and explicitly tell tar to use stdin, not to just assume it. -Erik Add install_utils and install_target_utils targets, so people that don't like my amazingly cool ldd and readelf tools, can (most unwisely ;-) ignore them. -Erik Bump version number to 0.9.9 Add in a configurator script. Now people can put stuff like this: Add an example of how to use this thing. Cleanup grammar and wording Add in syscalls.h for mipsel, thanks to Steven J. Hill. Remove and ignore generated syscall.h files from sparc and mipsel. Scrub up a few little things. Fix hstrerror Several little additions and cleanups. Add getw() and putw(). Add in some missing header files (netipx/ipx.h include/lastlog.h include/sgtty.h include/sys/perm.h) -Erik Update the working apps list. Not 100% completed, but getting close and I'd rather not lose this... This has taken a _lot_ of time... -Erik Don't free memory prematurely Fix some typos... Add in a weak for __adjtime Oops Grr. I should learn to compile stuff before committing procmail now works I just wrote up gethostent(), sethostent(), and endhostent() -Erik Add in a weak __mempcpy for mempcpy to make certain GNU programs happy. bother... Do not expose the weak_alias() junk to the world. Wrap it inside an #if defined _LIBC -Erik Oops. Fixup the defaults Add in support for the Hitach H8/300H architecture, contributed by Yoshinori Sato <qzb04471(a)nifty.ne.jp> Allow sparc code to at least compile Oops. Add a config file for sparc Add include guards Be consistant about the ways in which asm/unistd.h might be included to avoid gratuitous conflicts... This is a hack till we have proper _syscall macros for all archs. -Erik A few more little cleanups Adjust sparc port do it now actually works. -Erik Fix path Fixup arch substitution Fix headers Minor cleanups Rework powerpc to be consistant with the other arches. -Erik Fixup mips so it now works and provides basic functionality Fix naming error in brk.c, enable faster malloc by default Make powerpc default to faster malloc Update changelog Update text for release use X/Open __sysv_signal name, then use the weak name for sysv_signal -Erik OOps. Fix __adjtimex symbol Updates from Martin Sieper Dont choke when chown fails. Try to be more portable... HAVE_SA_RESTORER is supposed to be true, not false, on most arches. -Erik Mark Robson noticed that our strcasecmp() behaviour was not standards compliant. Brian Stafford then provided these new implementations, which apprear to properly follow SUSv2. -Erik Fix silly buffer overflow Several test suite updates. The testatexit, teston_exit, and pthread tests were contributed by Stefan Soucek A number of naming updates in preparation for adding in proper threading. Most of this is from Stefan Soucek, with additions and changes as needed from me. Fix copyright message Fix missing longjmp symbol Disable a lingering bit of wide char junk Geoffrey Espin noticed a $ that should have been a double $$ since Make make eats $'s. Patch from Yoshinori Sato <qzb04471(a)nifty.ne.jp> to fix up ptrace for the Hitachi h8300 Several mips cleanups/additons from Geoffrey Espin. Use sizeof(sa_mask) instaed of sizeof(sigset_t) since sa_mask is not always a sigset_t... Fix from Geoffrey Espin. A ton of cleanups. Eliminate some useless code. Much better debugging code now. -Erik Eliminate circular dependancy A few more little fixups Some more updates. Darn -- arm needs the mprotect hack Fix defines so debugging works as expected Whine and exit if people link against GNU libc or GNU libc linked shared libraries. Support strong_alias and begin merging usage of weak_function Make shared libs properly list the correct ld.so in the interp field by being sneaky. Miles Bader writes: Programs that don't use stdio crash in the `exit' function, because they call through the pointer__uClibc_cleanup, which has a value of 0. It has a value of 0 because __uClibc_main.c initializes it to the address of `__stdio_close_all', which is a weak symbol (and so is 0 if stdio is not used). This patch from Miles fixes it, though we need to audit __stdio_close_all usage to be sure... Doh! Rename __stdio_close_all to __stdio_flush_buffers. Eliminate an unnecessary variable Doh! Miles Bader noticed a couple of spots where I forgot to mark __stdio_flush_buffers with weak_function. Oops! Add a test from Stefan Soucek for pthread_cond_timedwait(). On mmu-less ARM perhaps sigsetjmp() isn't working? Merge in the pthread library. This is the linuxthreads library taken from glibc 2.1.3 and ported to work with uClibc by Stefan Soucek and Erik Andersen (me). Stefan has hacked things up such that linuxthreads runs on MMU-less systems (tested only on arm-nommu). Erik cleaned things up and made it work properly as a shared library. -Erik Several needed cleanups to the gcc wrapper. -Erik Enable thread support This is a bit less messy oops. I had accidentally typed in "clean" when I meant "clone". This fix makes pthreads actaully work on powerpc. -Erik Fix from John Rigby to fix stat() so it actually works. Miles Bader noticed that I'd messed up by always pulling errno in, regardless of whether it is being used... -Erik Add ldexp to the !C99 list, since it is defined in POSIX as being part of the classic math lib stuff. -Erik Lose the _GNU_SOURCE and just add __USE_GNU to the one file that needs it, since we definately do not want silent remapping of functions to their large-file counterparts. -Erik When vfork is not available and we have an MMU, then use fork() -Erik Oops. I forgot to commit this file... Update string tests per glibc 2.2.5's string tester. Looks like our stpncpy is flunking... -Erik Let the large file stuff be cancelable Several mips fixes from Geoffrey Espin. With these, busybox with ash/vi/etc now works just fine with uClibc on mips. This should be a little better... Test for libcrypt (which is partly broken ATM) Update todo list Per discussion with Manuel, when we call __stdio_flush_buffers from abort() and from _exit(), we need to ensure that flushing will not cause us to block. So use fcntl to set the fd's to non-block mode... Add a better error msg Fix a corner case which I had botched. -Erik Several naming cleanups so threads work properly again IEEE Std 1003.1-2001 says that the "fclose() function shall fail [with] EINTR [when] the fclose() function was interrupted by a signal". But looking in the current uClibc stdio.c for some bizarre reason we had a special case where when errno was EINTR, we would keep on trying instead. Doh! Fix that, -Erik Fix the compiler wrapper yet more... Support isblank() Both Miles and Manuel complained about this one. I was silently losing all -Wl calls... Yet another iteration... Joerg Schmitz-Linneweber recommends using tar -f - instead of -O to prevent interference with the TAPE env var Try this version instead... When messing with fd NONBLOCK status, put things back the way we found them afterwards. As was, this hosed things up for fds shared with a parent process. Very bad for shells... Oops. -Erik I shouldn't try to program when sleepy, since I totally botched the fcntl interface... -Erik Remove elimination of __BEGIN_DECLS/__END_DECLS Adjust function naming and make sure everything is properly static to avoid symbol leakage. -Erik Patch from Miles Bader: All the -M* options should suppress linking (right now, only `-M' does). Enable pread/pwrite Thomas Fritzsche noticed that __open_etc_hosts was only changing a local copy of the FILE pointer, thereby causing /etc/hosts lookups to fail with Resolver errors. This patch from Thomas fixes the problem. Fix rpc + threads so it now compiles. Proper support for setting h_errno Patch from Miles Bader to restrict common truncate64/ftruncate64 syscalls to 64-bit systems, since we can't be sure that the _syscall macros can cope with 64 bit args on 32 bit arches. Remove an erroneous -L- Don't try to return stuff from void funcs Odd. This seems to be in the wrong spot... Give the label a ; so compilers have no excuse to whine Fix redefinition problem Fix redefine problem Doh! Tests were not being compiled with warnings and optimization don't pretend to be reentrant yet Be consistant and use an unsigned char * throughout Don't redefine stuff Add an md5crypt test A few more little cleanups Lose the -nostdlib, which causes problems with older binutils, and add some fflush calls, since it seems streams are not flushed before an exec Fix C++ support Remove some debugging code Patch from David Schleef to check for proper 16-byte aliged stack pointer on powerpc Major rework of the include files to eliminate redundancy and to better support each arch. This is a really big patch... -Erik Patch from M. R. Brown <mrbrown(a)0xd6.org> to fix pthread support for SH, and fix vfork Fix for some comments, from Miles Bader Patch from Miles Bader to allow Large File support on the v850. oops. I forgot to commit this... Patch from Steven J. Hill to allow both mips and mipsel to be built Doh! Doh! Doh! Doh! Doh! A search and replace bug... Move syscall.h generation to the top level Makefile -Erik Remove generated stuff, restore sh/sys/procfs.h from M. R. Brown Remove sys/io.h include, since not everyone has it Seperate out the symbol resolution debugging, so it doesn't clutter things up when we don't care about symbol resolution problems. Make the lib loader always look first in the directory where the shared lib loader was found. -Erik Avoid forced -lpthread lnkage when threading is enabled Add in this missing header file Don't install CVS files into the devel dir Allow some failures to simplify building gcc Fixup ldd behavior to match recent ldso change Fix broken links Add thread support. Eliminate the useless extra "s Fixup redefinition of NL_ARGMAX Fix thinko Fix a segfault in scandir for empty directories. After looking over our version, I'm adopting the scandir from glibc (with minor changes) instead as it seems simpler and already correct. Remove the chdir, so we can test things like empty directories Merge in an ugly pile of rand* functions from glibc. :( Build our own crti.o and crtn.o with a cross arch method that I can live with much better the what glibc does. -Erik Remove an unused variable Add some symbols needed for C++ to work. Temporary hack... This should be the last piece needed to make constructors work (using a native gcc toolchain). The gcc wrapper still needs some touchups, but we seem to be _there_. Also some touchups to try and shrink uclinux binary sized by stubbing out unneeded stuff. -Erik Add implementations of strtof() and strtold(). These are a bit lame, since internally I'm just using strtod, but that keeps things small, and has the side effect of making these easy to write. -Erik Do not enable debugging for initfini.s and friends. Won't work anyways. -Erik Don't call null ctors/dtors. -Erik Setup so ctors/dtors can run. Disabled for now, since they do add a little bit to binary size... -Erik Oops! When I fixed the debug flags, I forgot to make things be PIC, so do that now. -Erik Update the config script to behave a bit better Fix link to daily snapshot Fix non-elf support (in theory). Revert misguided change suggested by arcturusnetworks, since Miles Bader reports it is unnecessary. -Erik Hide libc specific junk inside a #ifdef _LIBC to avoid namespace pollution, noted by Miles. -Erik Support gnu error(), patch contributed by Andrew Ip <aip(a)cwlinux.com> Add missing updwtmp() and fix broken makefile Fix location of crt0.o Don't let this worry about _init and _fini Add strptime, and commonize some locale strings -Erik Oops. Forgot to check this one in Build crti.o and crtn.o with optimization enabled -Erik Remove the C++ support stubs, since these now live elsewhere and these stubs were preventing the real stuff from working properly. -Erik Enable trace support by default, since it only costs 300 bytes anyways, and people seem to expect it. -Erik Add initial support for compiling cpp code. -Erik Let older arm cross compilers work -Erik Cleanup header files a bit. -Erik Resolve symlinks when determining the real ld.so path, which is now used as the default library search location. -Erik Bart Visscher <magick(a)Linux-Fan.com> has added some missing IPV6 support, and added several additional reentrant networking functions such that iptables now runs with IPV6 support. Merge glibc random, which gets us a much better RNG and a reentrant one as well. It is not much bigger than what we had, so... -Erik Fix missing defines. Forgot to check this in. -Erik Revert my symlink detecting change for now, since it breaks things. -Erik Add new debug target (disabled by default) so that when debug is on we now default to resolving symbols permanently.. -Erik Initial mips ldso porting effort from Steven J. Hill. Not yet complete, but off to a fine start. Prevent uninitialized use Attempt to follow symlinks if possible, and use that directory for the base library directory. -Erik s/off_t/__off_t/g Fix compile problem when ASSUME_DEVPTS=false getpt.c: In function 'getpt': getpt.c:83: 'have_no_dev_ptmx' undeclared ... oops. -Erik Doh! search-n-replace bites again Patch from Bart Visscher <magick(a)Linux-Fan.com> fixing some missing pieces of the conversion to reentrant functions. Update Changelog in preparation for a release. -Erik Compile in flockfile and friends by default -Erik Support getttyent and friends so ncurses will compile Bump up version number Update TODO list for next release Alphabetize Fix anon password Update webpage Update the FAQ a little bit Be kind to robots Add the ttyent.h header file Always build the utils. Always clean libc/misc, since there is some auto generated stuff in there -Erik Put the chdir back, to simplify testing now that scandir doesn't segfault anymore Add some phony targets Update webpage a little bit for clarity Fix grammar Remove include file, in case it is broken. We don't need it here. -Erik Fix incorrect ordering of -L and -l options, which prevented things like iproute2 and XFree86 from linking. -Erik Patch from Miles Bader to be less militant when doing a make clean. Add in a knob to disable %m support -Erik It doesn't make sense to supress linking for -i or -r, -Erik Include our own copy of struct sysinfo to avoid binary compatibility problems with Linux 2.4, which changed things. And thereby reduce by one more the kernel headers we depend on... -Erik Patch from Steven J. Hill to fix pthreads on mips Patch from Steven J. Hill to disable __fsetlocking when threads are disabled. Bug is my fault. oops. -Erik Mips config fixes from Steven J. Hill Implement sqrtf(), needed for libstdc++ on arm -Erik More mips support from sjhill Add in support for ftruncate64 on both ARM and x86 -Erik Add support for getrlimit64 and setrlimit64. Fix some problems with the getrlimit and setrlimit syscalls. -Erik Rework __gen_tempname() to better match glibc, and add mkstemp64(), which is needed for busybox ash when using largefile support. -Erik Add glob64.c, and add support for glob64 when large file is enabled. -Erik Patch from Miles Bader to fix the spots I'd messed up. Patches from Yoshinori Sato <qzb04471(a)nifty.ne.jp> to fix h8300 support for pthreads and update for the latest and greatest. Remove function declartions from include/features.h, create a separate header file for those, and fixup references. -Erik Last bit for old config system Doh! This is _still_ wrong. Fix potential buffer overflow. -Erik Steven J. Hill's latest mips dynamic loader updates m4(a)brecis.COM noticed a typing problem with the getuid syscall. OOps. Steven's patch contained a spare SEND_NUMBER_STDERR call that was spamming us. Kill that. My bad for not spotting that when merging. -Erik Remove unused variable -Erik Remove gratuitous symlink trashing Run dos2unix on these files run dos2unix on these files Adjust beinning Doh! I forgot to commit this... Be certain that Add the xopen swab() function, contributed by Kensuke Otake <kensuke(a)phreaker.net> Since pthreads work on powerpc, at least mention the option. Richard June <rjune(a)bravegnuworld.com> noticed that setutent was only opening utmp readonly. Oops. Patch from Jim Treadway <jim(a)stardot-tech.com> to eliminate use of alarm() and therefore SIGARLM in the resolver and to instead use select, which is much cleaner. Richard June <rjune(a)bravegnuworld.com> noticed that pututline was only writing the first sizeof-a-pointer bytes to the utmp file. oops. -Erik A ton of updates from Dwayne Fontenot <fontenot(a)jacques.activebuddy.com>. Thanks Dwayne! Revert this file back to where it was so m68k can compile again. Oops. I'd hosed things up for m68k with the header file rework. -Erik Teach initfini to build properly on arches where gcc tries to be sneaky behind our back... -Erik Add a fun pointer to make apps happy Patch from Axel Barnitzke <barney(a)xkontor.com> to fixup a problem with getpass() echoing passwords... Faster implementation from Miles Bader Add libungif-4.1.0b1 undefine __USE_FILE_OFFSET64, since we absolutely do _NOT_ want interfaces silently renamed under us or very bad things will happen. In this case, statfs64() ended up recurively calling statfs64() instead of statfs().... -Erik Avoid defining __USE_FILE_OFFSET64, since we do _NOT_ want interfaces silently renamed under us or very bad things may happen... -Erik Support ISblank properly Per discussion on the mailing list, fix getpass properly. -Erik Create a much more careful ftruncate64 implementation, that should address all the concern Miles had with the earlier versions... -Erik Remove from syscalls.c, leave just ftruncate64.c and truncate64.c which have implementations that works... -Erik Add truncate64.c Re-enable clnt_perror. Patch from Miles Bader. Add creat64 -Erik Fixup __USE_FILE_OFFSET64 Add finite() to C89 math lib, since it is needed... -Erik Bump up version number... Russ Dill noticed that the symlinks for libpthread didn't match the other links. Fixed now. -Erik Some minor updates per discussion with Miles Bader -Erik Fix libpthread compile for sparc Mention pthreads for sparc Teach powerpc to whine loudly about using -fPIC when a R_PPC_REL24 is encountered... -Erik Update Changelog John Traill <john.traill(a)motorola.com> noticed that on powerpc a dev_t is _not_ a quad type, but a simple int. Doh! We fixed that months ago, but subsequently lost the fix, so this restores things. SEND_NUMBER_STDERR is supposed to be calling _dl_simple_ltoa(), not _dl_simple_ltoahex(). Numbers are not supposed to be in hex. -Erik Add a list of known bugs. Update the docs in preparation for a release. -Erik A last minute addition Minor doc update Update TODO list Patch from Jim Treadway <jim(a)stardot-tech.com>: The internal __getgrent function doesn't allocate enough memory to hold the trailing NULL pointer in the gr_mem member of the returned 'struct group *'. Fixed stpncpy() implementation from Manuel Manuel and I were looking into a problem with applications failing to link (undefined reference to `main') when the .o file containing main was contained in an static library(a '.a' ar archive). It turns out that due to its single pass nature, GNU ld was failing to pull it into the build. This sticks a dummy reference to main() into crt0.o, so that when an application is linked with the main() function in a static library, we can be sure that main() actually gets linked in. -Erik Fix dummy main reference so it works... Remove strong aliases to symbols that we don't define in uClibc Stub out pread and pwrite when not available Patch from Martin Proulx to remove weak_aliases for non ELF compilers in __uClibc_main for the _stdio_init and _stdio_term functions. Since weak_aliases are defined as hard aliases for non ELF compilers, these 2 symbols ended up to be multiply defined, as those two are defined in stdio.c. Patch from Martin Proulx to not do ELFish things when not ELF. Patch from Mike McDonald to make gethostbyname_r() not fail for things like gethostbyname("192.168.0.1"), which should work even when the /etc/hosts and /etc/config/hosts files do not exist. Patch from Axel Barnitzke <barney(a)xkontor.com> to add basic support for struct _res. This is a minimalist implementation, but should work for most anything out there. Patch from Axel Barnitzke <barney(a)xkontor.com> to fix handling of the isinf() macro, which was a casulty of my grafting the glibc header onto out math library. Minor updates. Add support for mmap64 -Erik Don't use $(PWD), use $(shell pwd) instead Bah. Fix (non)password issue. Rework libcrypt based on the openbsd crypt implementation so that it passes the DES validation suite. setkey_r, encrypt_r, and __des_crypt_r are not really reentrant now, and that should be fixed (or we should drop crypt_r and friends which are not supported by SuSv3). -Erik Stupid libgcc.a from gcc 2.95.x uses __write in pure.o which is a blatent GNU libc-ism... Cope. -Erik Make ldd and readelf work even with byte swapped binaries Patch from Steven J. Hill <sjhill(a)realitydiluted.com>: Patch from Tobias Anderberg <tobias.anderberg(a)axis.com> to remove the .asm calls Add missing sysctl.h and queue.h Ensure that make clean really cleans up after itself Speed things up by eliminating lots of needless exec calls -Erik No real need to make ldd.target and readelf.target be static... When it is going to fail silently anyways, whine loudly and abort early with instructions on what to do... -Erik Fixup build a bit more Fix funky use of brackets Add missing braces Rework the math library tests per the glibc math test code, with many unsupported tests disabled for the moment. -Erik Fill a few little holes in the math library Another mips patch from Steven J. Hill: First pass attempt at an alpha port Implement readdir_r. Audit for proper thread safety and locking. -Erik Begin the process of reworking the time functions for proper time zone and locale support (in theory). More work is still needed. -Erik Oops. Stupid typo. Majorly rework to also cope with architectures which do not use the socketcall system call, but instead implement each fundamental networking function directly as a system call. -Erik Fixup for architectures that do not supply the ipc system call, but implement the ipc functions as separate system calls. -Erik Fix the defines which I had backwards Add a default syscalls.h that will just error out. Add in syscalls.h for alpha. Add a config file for alpha Fix this one up so it works Small cleanups for alpha Fix some silly bugs and type problems Several bugfixes for problems that showed up on alpha -Erik Fixes for 64 bit arches Use the default version in include/sys instead Add a missing #include Cleanup slightly Several h8300 updates from Yoshinori Sato <qzb04471(a)nifty.ne.jp> Send the -s to the linker Pass the -s to the linker Fix ldd so it correctly handles search paths of just one entry (per fix in ldso a while back), and correctly matches the search order in the shared lib loader. -Erik Fix libcrypt, thanks to Vadim Berkgaut <berk(a)rc.ru> Fix a couple of silly bugs I'd left in while fixing things -Erik Patch from Tobias Anderberg <tobias.anderberg(a)axis.com> to abstract out page alignment issues. As we we were assuming 4k pages, which need not be the case... Fixup and unifiy version numbering. Automate versioning updates. Propagate fixes across makefiles. -Erik Patch from Yoshinori Sato <qzb04471(a)nifty.ne.jp> to use C_SYMBOL_PREFIX for confused compilers, such as for v850 and h8300, per suggestion from Miles Bader. Update content a bit Now that was silly Silly me. ldd.target is for the target system, so don't use-build-dir when compiling... -Erik Cope with systems that don't glob all these together, but use separate syscalls. -Erik Make syscalls.c way more generic. Now works on alpha... -Erik Needed for the alpha port -Erik Fixup some silly bugs I added earlier -Erik Make these properly cope with 64bit systems -Erik Cool. An even better way to get the gcc include dir which eliminates several external program calls, thanks to a suggestion from rmk. -Erik Put GCCINCDIR here, which is the only place it is needed. -Erik don't include the linux dir. Pointless and broken. -Erik And with this, the alpha port is not basically working. -Erik Doh! A silly typo broke select... -Erik Fix dependancy for util target -Erik Fix dependancy. again. Fixup totally broken locking code... No storage for the mutex, wrong ifdef macro.. -Erik -#ifdef _POSIX_THREADS +#ifdef __UCLIBC_HAS_THREADS__ Rework setenv, getenv and friends per the latest glibc code, but cleaned up for readability. Merge in putenv. Add clearenv as a side effect. -Erik Patch from Robert Griebl <griebl(a)gmx.de> to support getusershell() and friends. Doh! Oops. Forgot to check this in. Thanks Martin Volf for noticing -Erik Kill the libc-lock headers, which we do not use and which are not correct for uClibc. Fix setenv locking to behave itself. -Erik A patch from Ted Phelps to fix popen(). Ted writes: There is a minor bug in the implementation of popen(). In the case where the file descriptor returned from its call to pipe() is the same as the file descriptor that it is meant to be (where the dup2() branch is not taken), the end of the pipe is still closed by close(reading) even though it shouldn't be. Thanks Ted! This patch from Rik Faith <faith(a)alephnull.com> fixes a potentially non-NULL terminated string problem that could result from the use of open_memstream(). Manuel may have a better solution, but this one works for me, since with this plus the popen fix I can now run things like gdb properly. Thanks Rik! Yipe. As Joseph Chiu noticed, sockvec is supposed to be an int* not an int. Write a new strxfrm that doesn't make function calls. Uses the same logic as before but unrolls the func calls and thereby eliminates some steps and some bytes. Now adds just 40 bytes to .text. -Erik Cleanup the mess, remove now obsolete files -Erik Silence warnings, clean things up. -Erik Don't use fixed buffers if we have an mmu such that malloc and realloc are cheap. -Erik Begin efforts at reentrance by seperating out the stuff that isn't reentrant and labeling it, and making everything else const. -Erik Fix pthreads to use the rt signals if present -Erik Fix a silly bug... Prevent buffer overflow Implement ttyname_r -Erik time() is implemented in syscalls.c -Erik Add support for sigtimedwait and sigwaitinfo -Erik Ah kant spel mi name Some cleanups so utmp/wtmp behaves. Fix potential use of uninitialized memory. Prepare to reentrantify the utmp stuff. -Erik Shuffle the logic around a bit Shuffle the logic around a bit -Erik Implement strerror_r. This is per SuSv3, not glibc which does something different. -Erik Re-backport all the rpc stuff from glibc 2.2.5. This allows us to make this junk (and I do mean that ;-) thread safe without undue pain. Adds 12k worth to the code size I'm afraid, but since I never use NFS and therefore never include this stuff, I guess thats acceptable. I still need to enable the multi-threaded bits... -Erik Make things more re-entrany, kill some cruft. -Erik kill cruft Update rpc headers. Add missing some headers -Erik Patch from Martin Proulx <mproulx(a)okiok.com> to support the i960 architecture. Some commentary -Erik Fix locking. Kill Fix thread locking so it works -Erik Rework and kill pointless static variable -Erik Silly name change Rework, reduce the size, add proper locking -Erik Kill kernel_version.c, which is completely meaningless crap and didn't even work. -Erik update as far as i've double checked things thus far -Erik Eliminate all the pointless globals from getcwd(). Default to using the getcwd syscall instead, when it is present. -Erik Make sure the sccsid tags never get compiled in. -Erik Cleanup the getcwd implementation (again) since I broke it last night. Restore malloc-ing when buf=NULL for the syscall version... Move getcwd to libc/sysdeps/linux/common and out of syscalls.c so there is just one getcwd.o object present. -Erik A simple test for getcwd -Erik Oops. Looks like I broke ttyname. Fix it. -Erik Fix incorrect comment re malloc-930716 -Erik Fix DNS resolution so that it once again works. I'd broken it when adding some locking code. -Erik Several test case cleanups -Erik Fix a bug reported by Michael Weiser <michael(a)weiser.saale-net.de> which could cause incorrect invocations of g++. Cleanup a few things. Add a new --uclibc-ctors flag allowing one to apply ctor/dtor support to regular C code. -Erik Some Rules cleanups, better gcc-3.1 support. -Erik Cleanup the function pointer comparisions -Erik Add support for doing the mmu-less thing -Erik Update the webpage for release -Erik Commit the full changelog since the last release -Erik Some release notes -Erik Update the README a bit -Erik Kill this file. Don't need it. -Erik Update my TODO stuff Last Changelog update Remove noise Fix spelling Fix support for 2.0.x linux kernels. Oops. -Erik Fix silly spelling error Fix spelling Rework compiler optimization code to be smarter -Erik Don't try to compile the target utils unless told to do so. -Erik Fixup target util handling -Erik Per "Marshall M. Midden" <m4(a)brecis.com>, remove double define of _PATH_LOCALE. Several cleanups/fixes from Marshall M. Midden <m4(a)brecis.com> This patch, from Ronald Wahl <rwa(a)peppercon.com>, fixes the spots where I screwed up and forgot to fix realloc to use free_unlocked() instead of free(). Thanks Ronald! Patch from Ronald Wahl <rwa(a)peppercon.com> -- kill references to the obsolete PTHREAD_MUTEX_FAST_NP, and change the default mutex type to adaptive Change the default structure of the installed toolchain -Erik fix this header so it behaves itself -Erik Fixup where locals shadowed globals -Erik Resync the install defines -Erik Add a bunch of extra pedantic annoyingly strict checks -Erik Disable ldconfig.target for now -Erik openlog could deadlock when called from vsyslog, so allow recursive locking, -Erik Oops. missed a spot -Erik Fix clone so it compiles -Erik Make clone work, part 2. -Erik Add a weak to make apache happy -Erik Only enable elf2flt support when using elf toolchains -Erik Stupid filesystems like cramfs fail to guarantee that st_ino and st_dev uniquely identify a file, contrary to SuSv3, so we cannot be quite so precise as to require an exact match. Settle for something less... Grumble... -Erik Patch from Larry Doolittle <ldoolitt(a)recycle.lbl.gov> to cleanup connect_dns() and simplify IPV6 support by reducing the number of ifdefs sprinkled about. Kill namespace pollution in getrpcent.c. Silence other rpc warnings by fixing prototypes. Fix global stuff so it should behave itself properly now, -Erik Cleanup namespace leaks by prepending __ to global stuff to indicate it is (alledgedly) private. -Erik Fix namespace pollution by hiding statfix and statfix64 by prepending an __ to the name. Not perfect but better. -Erik Doh! search-n-replace strikes again -Erik Finer grained locking in __connect_dns() so we don't hold the lock while sending packets out onto the wire. -Erik Fix a typo Patch from Ronald Wahl <rwa(a)peppercon.com> to fix a memory leak Add missing stropts.h Per bug report from Ronald Wahl <rwa(a)peppercon.com>: ...inet_pton breaks since tolower is implemented as a macro and its argument is evaluated more than once: Tobias Anderberg <tobias.anderberg(a)axis.com> noticed that we were opening the socket() as SOCK_STREAM instead of using SOCK_DGRAM like we should have done. The mips config files were broken, and failed to define NM for some reason... Note updated toolchains are available -Erik Kill this stale file Add missing pthread_condattr_getpshared and pthread_condattr_setpshared -Erik Add both pthread_mutexattr_setpshared() and pthread_mutexattr_getpshared(), which were missing -Erik Rework pread and pwrite support so it should actually work. Add support for pread64 and pwrite64. Fixup llseek a bit. -Erik Silence a couple of silly warnings -Erik Patch for a silly bug from David Blythe stupid cut-n-paste bug -Erik Do not assume NULL termination on the ut_id field. Thanks to mac12(a)po.cwru.edu for spotting this one. Odd. Got a copy of junk in here. Disable debug stuff by default __morecore need not be a function pointer We don't need the debug versions Fix from "Gerhard Uttenthaler" <uttenthaler(a)ems-wuensche.com> so that cfsetspeed would actually be compiled in. Miles Bader implemented a new mmap based malloc which is much smarter than the old "malloc-simple", and actually works, unlike the old "malloc". So kill the old "malloc-simple" and the old "malloc" and replace them with Miles' new malloc implementation. Update Config files to match. Thanks Miles! Fix spelling Rework syscall handling. Rewrite syscall handlers for x86 and ARM. Prepare to kill the UNIFIED_SYSCALL option and instead have it be a per arch thing that is either enabled or not for that arch. -Erik Add some syscalls which I moved out of syscalls.c -Erik Add support for people calling syscall() -Erik Take advantage of the new syscall stuff on x86 and arm to kill the ldso specific syscalls and use the generic ones instead. -Erik Implement syscall() for arm -Erik Kill cruft. Build ldd for the host system by default. -Erik Cleanup from Neal Crook fixing some formatting and eliminating some "sh: cd: ./lib: No such file or directory" errors. The __set_errno macro _must_ match that defined in include/bits/errno.h. We can't tack in the return -1 since then when people include errno.h, the return -1 mysteriously vanishes... Setting the __set_errno back and restoring the 'return -1;' calls to each _syscall[0-n] macro makes mips syscalls work again. -Erik Kill ill advised find command that was not doing anything productive, but did annoying things instead. -Erik Ok, I get it. sjhill kept adding the 'find' command since include/sgidefs.h wasn't getting scrubbed. Fix it so this symlink gets properly scrubbed, even for mipsel. -Erik Oops. I accidentally omitted the actual mknod() function. -Erik Avoid errors in case some loon has explicitly included linux/kernel.h (even though doing so is very dumb). -Erik Always build utils by default -Erik You fool foolish. Goodbye level 2. Patch from Alexander Pevzner <pzz(a)pzz.msk.ru> to fixup things when invoked as the C++ compiler to to automagically add include/g++ into the include search path, and automagically add -lstdc++ and -lm into the set of automatically linked libraries. Patch from Martin Proulx <mproulx(a)okiok.com> to fix i960 create_module() support. More i960 support Per discussion on the mailing list, simply vfork -> fork mapping to only apply iff we do not have vfork available, which is simpler and more reasonable. -Erik Sigh. A bit more cleanup. Joseph Chiu <josephc(a)idealab.com> found an off-by-one bug. oops! When DODEBUG and HAS_WCHAR were enabled and HAS_LOCALE was disabled, wchar.c wouldn't compile: wchar.c: In function `__mbsnrtowcs': wchar.c:631: `__ctype_encoding_7_bit' undeclared (first use in this function) This fixes it by keeping the locale specific asserts hidden when not relevant. -Erik remove BUILDTIME since it is not used Just in case, crash if somehow `exit' returns anyways -Erik Unify calloc (its the same thing regardless of the underlying malloc implementation). Fix problem reported to bugtraq about problems with integer overflow that can occur during the computation of the memory region size by calloc (and similar functions) which could result in a subsequent buffer overflow. -Erik Rework RPC code once again. By default, only enable the stuff needed for NFS mounts, rsh, and similar. -Erik Fixup the last missing pieces of thread locking -Erik Several pthreads updates. Enable linuxthreads_db. Several fixes related to thread local storage. -Erik When symbols are missing, its supposed to be an error... -Erik Per suggestion from Miles Bader, move calloc.c to libc/stdlib. Also, Manuel notices that I forgot to check for when nmemb=0, which would result in a segfault, so fix that case as well. -Erik Message catalog support for internationalization is not currently provided by uClibc, and here I have added macros to disable it. -Erik Apply integer overflow security fix for "CERT Advisory CA-2002-25 Integer Overflow In XDR Library" http://www.cert.org/advisories/CA-2002-25.html Patch from Solar Designer <solar(a)openwall.com>. Updates to the working apps list from Kagan Kongar. Thanks! getopt tests missed a file rework getopt. no read need to split this one up since the parts are so tightly coupled. Rewrite getenv Changed my mind. Keep this separate. -Erik Remove some noise Cleanup crypt and remove the crypt_r stuff, since SuSv3 (IEEE Std 1003.1-2001) states that crypt need not be reentrant. -Erik Add getrpcent.c to default rpc build Cleanup to avoid some undefined behavior -Erik Avoid bad things happening on macro expansion... -Erik Cleanup some silly warnings Add missing include file Cleanup warnings and fix prototypes -Erik Fix locking Fix locking -Erik Make some strings const -Erik Update status of reentrance support Update default config files Disable unused unifed stuff -Erik Remove unified syscall support (it should just be a per-arch decision, with syscalls.h adjusted to match). Add symlinks to make tools like mklibs.py be happy. -Erik Fix a silly bug with using fstat64 instead of just fstat. No reason for 64bit stuff just to check perms. -Erik I missed a file Make pump happy. Add in this header. -Erik Patch from Stefan Allius and Edie C. Dost to let ldd and readelf compile under solaris. Patch from Stefan Allius and Edie C. Dost to add SuperH shared library support. This also adds some cleaner error handling, which I (Erik) then ported over to x86 and arm. In addition Stefan added the following fixes: Fix license. I meant to say LGPL... -Erik I reworked syscalls.h to match how I'm doing other arches. Stefan Allius and Edie C. Dost has some concerns about the perl script used to general crti.o and crtn.o and added their own versions. These versions will win since they are built last, Missed a spot -Erik Patch from Stefan Allius and Edie C. Dost: In linuxthreads/errno.h the functions __errno_location and __h_errno_location wasn't safe against calling before the library is initialized. Add a simple test for shared lib ctor/dtors -Erik Shuffle things around a bit. Looks a little cleaner. -Erik Move destructor attribute tag Bump version to 0.9.13 Update the FAQ Make powerpc compile once again -Erik Oops. missed a spot. -Erik For some perverse reason we were not registering destructors for dlopen'd libraries. This fixes that. -Erik Fix a stupid typo messing up powerpc support -Erik Disable this code for mips, which does things quite differently... -Erik Patch from Stefan Allius to remove obsolete printfs Cleanup error returns to avoid warnings -Erik Patch from Stefan Allius, avoid compiler warnings (unused variable) Doh! I broke it. oops. Patch from Stefan Allius to fix it. Be more path independent Link ldso vs libgcc.a and eliminate baggage caused by not previously linking vs libgcc -Erik New and improved fork for mips, thanks to the fine folks at Brecis Communications. Initial piece of unified syscall support from Brecis Communications Add in __uClibc_syscall Ok, bad idea. didn't work. -Erik Update todo list a bit Update Changelog for release -Erik Update webpage for release update todo again Add missing thread-safe locking. -Erik Move old stuff into old-news spacing Fix spacing Ugh. Make uClibc cross compile with gcc 2.95.x and threads. I wonder if this is serious enough to warrent 0.9.14? -Erik Geez I'm an idiot some times. I shouldn't code when I'm exhausted. I _totally_ screwed up the locking on exit and atexit such that it didn't do any good at all. -Erik Fix alignment, minor cosmetic changes -Erik Fix use of __pthread_once, and fix rpc usage of thread local storage.... -Erik Test threads when appropriate Fix the gcc wrapper to include crtbeginS.o and crtendS.o when we are compiling PIC code, and use crtbegin.o and crtend.o when compiling non-pic code. As was caused problems, esp on powerpc... -Erik Doh! missed a spot. -Erik I missed a spot. -Erik Only try to install existing binaries -Erik Update to version 0.9.14 -Erik Add missing include/thread_db.h file, as reported by Simon Posnjak -Erik Move all malloc tests under test/malloc/ Do not prevent people from making mmu-less builds on mmu-full systems. -Erik Patch from Jarkko to fix drand48 to not use long long when long long support is disabled in the uClibc Config. Remove h8300 special case Replace all instances of _LIBC_REENTRANT with __UCLIBC_HAS_THREADS__ -Erik Demonstrate that dlopen() RTLD_NOW is currently broken. -Erik Cleanup exit a bit, from Ronald Wahl Yet more rework to make __getgrent and the functions that use it reentrant... -Erik Directly use kernel types for uid_t, gid_t, and dev_t to avoid the need to translate these entities... -Erik Be prepared to call __pthread_initialize_minimal Open a lib that is not so closely coupled with gdb Based on work by Stefan Allius, arrange for early initialization of pthread stuff. Also, don't bother building libthread_db unless we are debugging. -Erik Work from Stefan Allius which allows superH to use the common method for building crti.o and crtn.o Call the pthread setup junk early if possible. Add a .note section to make gdb happy some updates from Stefan Allius to make up the SuperH shared lib loader build properly. Mostly just sprinkling casts, and making static some things that should be static. missed const-ifying this one. SuperH config update Fixup struct _res handling so apps using struct _res can actually compile ("worst standard ever!") -Erik Eliminate wrapping of struct stat and use the kernel version directly. Eliminate all the attendant baggage. Fix internal types to match kernel types more closely. -Erik Only build libthread_db when both threads and debug are enabled -Erik Stupid cut-n-paste error Remove some noise mode_t was being promoted to an int by gcc's __builtin_va_arg, causing bad things to happen. This makes it explicit, so pthread using apps are no longer broken... -Erik Revert mode_t change. Sigh. As Manuel so eloquently put it: "this is the way we hose our code... hose our code... hose our code... this is the way we hose our code... all thanks to glibc" -Erik Hide .hidden stuff unless explicitly enabled -Erik Support _syscall6 and _syscall7 for arm -Erik Rework errno handling to be kernel header free -Erik Rework struct stat/stat64 handling to eliminate kernel headers -Erik Ignore generated binaries Split out the arch dependant errno_values.h junk into arch dependant files. -Erik Fix broken link Split out the definition of struct stat into the new arch specific bits/kernel_stat.h file. -Erik Break dependancy of bits/types.h on the asm/posix_types.h kernel header, which is not directly usable for many architectures. -Erik Break dependancy of bits/types.h on the asm/posix_types.h kernel header, which is not directly usable for many architectures. -Erik Ignore generated stuff Use bits/kernel_stat.h, not asm/stat.h -Erik Avoid `ECANCELED' redefined on mips -Erik Simple shared memory test ignore generated stuff Make shm stuff work properly. -Erik Finish off the bits/kernel_stat.h cleanup for proper __USE_FILE_OFFSET64 handling. -Erik Use the kernel version of struct msqid_ds directly, since we don't do any of that silly translating... -Erik Kill the HAS_LONG_LONG option. It really did not make a lot of sense to exclude it, gcc always supports long long, and we never fully excluded long long anyways (off64_t for example). -Erik Update version to 0.9.15 in preparation for making a release -Erik Make bits/kernel_types.h include guard names match the include guard names used by the kernel's asm/posix_types.h to eliminate gratuitous conflicts and let our file win over the very-likely- to-be-broken kernel header file. -Erik Oops. I got the include guard wrong. Fix it per current value in include/asm-v850/posix_types.h on cvs.uclinux.org -Erik Implement missing readdir64_r.c -Erik No need to hide this stuff when _DIRENT_HAVE_D_TYPE is not defined... Nothing too sacred in there and it can be used for other things... -Erik Move the _DIRENT_HAVE_D_TYPE test to avoid breaking fileutils -Erik Make sure that bits/syscalls.h always includes bits/syscall.h -Erik Semonstrate a problem where weak symbols referenced in shared libs are not being overridden when those same symbols _are_ overridden by other shared libs in the main app. Ick. -Erik Update changelog for release update for release Final update fix grammar Fix broken getpriority syscall, per email from Marshall M. Midden -Erik Fix a silly bug notices by Ronald Wahl <rwa(a)peppercon.com> Oops.

Oops. -Erik Support fstatvfs64 and statvfs64 -Erik Make sjhill happy, and revive memalign -Erik split-out memalign and realloc -Erik Add in some weak aliases to allow C99 apps to compile w/o defining _ISOC99_SOURCE, per what glibc does. -Erik Fixup multi-line string -Erik As noted by Bill Huang <billhuang(a)redsonic.com>, the gid and uid were reversed in putpwent(). Oops. -Erik Patch from Tiago Marques <tmarques(a)viaconnect.inf.br> -- fall back to using SOCK_STREAM if SOCK_DGRAM fails. -Erik Fix some locking problems noted by Manuel. __getgrent() was always called under lock, but the callers did not share the same locks... -Erik Don't run floating point opcodes when code is compiled -msoft-float -Erik Add missing _dl_dprintf arguments, as noticed by Tero Lyytik�inen <tero(a)paravant.fi> Some minor C++ support updates Fix a thinko -- I used the wrong symbol to check for LFS support. -Erik Fix stupid typo noticed by John Mullin <john.mullin(a)homenetcomm.com> Use __UCLIBC_HAVE_LFS__ not __USE_LARGEFILE64 to decide if 64 bit interfaces should be used. -Erik Update index Add url A bug fix from Alexey V. Neyman: A few additions Replace _LIBC_REENTRANT with __UCLIBC_HAS_THREADS__ -Erik Sigh. OpenBSD used /usr/bin/{true|false} This commit contains a patch from Stefan Allius <allius(a)atecom.com> to change how uClibc handles _init and _fini, allowing shared lib constructors and destructors to initialize things in the correct sequence. Stefan ported the SH architecture. I then ported x86, arm, and mips. x86 and arm are working fine, but I don't think I quite got things correct for mips. Patch from Stefan Allius <allius(a)atecom.com>: ----------------------------------- In extra/Configs/Config.sh I added the INCLUDE_PTHREADS statement and change the default values for BUILD_UCLIBC_LDSO and HAVE_SHARED. ----------------------------------- In extra/scripts/initfini.pl My last patch removes two labels, which migth be used by the .size statements. (Sorry, but I'm a perl beginner) I fixed it. ----------------------------------- In libc/sysdeps/linux/common/initfini.c I fixed two warnings "nested extern declaration of `i_am_not_a_leaf.. ----------------------------------- In libc/sysdeps/linux/sh/__init_brl.c brk.c sbrk.c I fixed some compiler warnings which comes from a wrong inclusion order. ----------------------------------- Patch from Stefan Allius <allius(a)atecom.com>: 'wcschrnul.o' appeares two times in MOBJW2 Patch from Marshall M. Midden <m4(a)brecis.com> to fixup crt0 for mips where I had made a mess Support O_STREAMING Octal to hex It turns out that __thread is now a gcc keyword. We used __thread in a few spots in our header files. In this change I do a s/__thread/__thread_id/ so we no longer conflict with newer CVS versions of gcc (such as the patched up gcc 3.2 included with RedHat 3.0). -Erik Patch from Christian MICHON <christian_michon(a)yahoo.fr> to reimplement my little initfini.pl script in awk. This eliminates uClibc's compile-time dependancy on perl, and lets us use the much lighter weight awk, which facilitates building uClibc standalone environments. Kill the now redundant initfini.pl -Erik Kill a warning. Patch from Joel Coltoff <joel(a)wmi.com> Remove -fuclibc-ctors Fix malloc so it compiles and works when using pthreads -Erik Add a test from Alex King <alex(a)morrison.king.net.nz> which shows a failure in ptsname when ASSUME_DEVPTS=false -Erik Add in an initial list of the differences between glibc and uClibc. This is not complete, but covers some of the main points. -Erik Echo mmu-less warning where appropriate This patch, based on a patch from Stefan Allius, lets us pick an appropriate awk implementation at compile time, so we can again compile on Solaris and whatnot. -Erik Update freeswan entry, per success report from Arne Bernin When UNIX98PTY_ONLY was false, but Unix 98 ptys were in fact working and functional, everything would succeed but then we would return a failure due to a silly logic bug. This patch fixes it so things will work correctly regardless of the UNIX98PTY_ONLY setting. -Erik A patch from Arne Jonsson <arne.jonsson(a)i3micro.com> to allow uClibc's libpthread to run on linux 2.0.x kernels which lack poll() and therefore must use select() instead. Actually install libdl.a -Erik Be nicer to gcc -- add a link for crt1.o Overwriting the crt1.o link is fine Doh. Add a missing #include to interp.c. I wonder why it used to work? Perhaps the wrapper bug miles fixed? Regardless this is very much needed. -Erik Sigh. Lets not use LD to link, or we lose the INTERP field. -Erik Put it back the way it was. Sigh. Fixup depends Add in a horrible hack that seems necessary for the Hitachi SH processors to work properly. -Erik A patch from Arne Jonsson <arne.jonsson(a)i3micro.com>: Remove my horrible SH hack infavor of this fix for initfini.awk from Stefan Allius <allius(a)atecom.com>, which does a better job. For now, comment out the broken part Fix a silly typo for Manuel -Erik Use a nifty macro to make testing gcc features simpler and easier to read. -Erik Use '#ifdef __linux__' not '#ifdef linux' Fixup script to avoid potential spurious whining over empty object files. -Erik Add a simple realloc test -Erik Ignore generated stuff Ok, this commit is _huge_ and its gonna change the world. I've been working on a new config system on and off for about 6 months now, but I've never been fully satisfied. Well, I'm finally am happy with the new config system, so here it is. This completely removes the old uClibc configuration system, and replaces it with an entirely new system based on LinuxKernelConf, from http://www.xs4all.nl/~zippel/lc/ As it turns out, Linus has just merged LinuxKernelConf into Linux 2.5.45, so it looks like I made the right choice. Don't force gcc 3.2 on the world -Erik Allow 'make clean' on the test stuff to work with the new config system. -Erik Fix a lingering reference to Config -Erik Skip the dependancy on .config for now Oops. Kill generated binaries. Make it so arch specific stuff can be simpler. Initial attempt at making CPU_CFLAGS, which should allow things to be optimized per-CPU and/or per-system. -Erik Don't assume i386 Fix udhcp link It looks like I lost DEVEL_TOOL_PREFIX. Put it back. -Erik Fix PIC configuration, so shared libraries once again work -Erik A few cosmetic adjustments, and fixup the makefile a bit Update TODO items update all the Config files for the various arches so they work with the new config system. Hopefully I got everything here correct... -Erik Default to SH4 kill some ancient stuff that appears to be lingering Use "include_config" not "include-config" Patch from "Cho, Seong-Myun" <smcho(a)xecurenexus.com> to limit things to the lower 16 bits of 'id'. Patch from M. R. Brown <mrbrown(a)0xd6.org> to get rid of "depreciated multi-line string literals" warnings Yet more config system updating. Properly prefix some symbols Another update to initfini.awk and initfini.c from Stefan Allius to hopefully address SH wierdness. Now works on other architecture properly as well. Several SH lib loader patches by Stefan Allius <allius(a)atecom.com> and "M. R. Brown" <mrbrown(a)0xd6.org> A patch from Vincent Sanders to fix the arm implementation of ioperm() and iopl() Oops. Fix compilation on arm. -Erik Add link to search google's uclibc archive Don't use ENTRY(), make the asm explicit -Erik Kill sysdep.h and fixup the SH asm to not use it. -Erik I dunno why there were align 5, but align 4 is much more sensible. Fixup so we use soft-float when HAS_FPU is disabled. -Erik Export TARGET_ARCH Patch from M. R. Brown to fix 'make defconfig' Patch from Stefan Allius. Include CPU_CFLAGS when compiling initfini Patch from Stefan Allius -- export LIBGCC Kill legacy DOPIC=true assignment Standardize LIBGCC_DIR Expand NIS comments A patch from Danny Lepage so that we do not setting on symlinks when looking for a device match, and instead keep looking till we find the correct device. Massive scrubbing of the shared lib loader error handling. Move all configuration options into the new config system. -Erik Fix gcc-uClibc.h dependancies Fixup handling of disabled options Cleanup soft-float support For now, leave the "Oddly enough, __fsetlocking() is NOT threadsafe." comment as an mjn3 only item. Cleanup patch from Simon Rowe Fix up a compile error Recognize 'n' tristate/boolean symbol value in the .config file, allowing more convenient manual editing of the .config file. Patch by Petr Baudis, skimmed from linux-kernel mailing list. Increase maximum .config line size to 1024. Update soft-float handling Add missing blank line Fixup function prototype for __uint128_t which fixes the compile on powerpc with gcc 3.2. -Erik Update doc reference Merge an update from upstream Large cleanup patch, based in large part on a patch from Stefan Allius, which adds a great deal of sanity. Update the docs Another SuperH patch from Stefan Allius. This make it so the SuperH lib loader can be compiled by GCC 3.3 Some minor changes from Stefan Allius to make conf and mconf compile under Solaris. Construct a default arm configuration Doh! Leave ldso debugging off by default.. Fix a silly compile bug Leave ldso debugging off by default Cleanup everything Add a default for sh Kill the now obsolete uClibc_config_fix.pl Add defaults for powerpc Add CPU_CFLAGS-y into LIBGCC_CFLAGS so multilibs gcc will behave itself. Revery the "=" to ":=" change, so people like Miles can set stuff in their .config Patch from Stefan Allius to fixup SuperH ARCH_HAS_MMU and ARCH_HAS_FPU Disble unimplemented function prototypes Patch from Stefan Allius for libgcc multilib support Use NATIVE_CC. Don't hard code using 'gcc'. -Erik Disable ldso debugging. It should not be on by default. Scare people away from enabling locale support for now. Re-enable the strchrnul and rawmemchr tests Patch from Stefan Allius: avoid implicit casting of void *(64bit) to int(32bit) Patch from Stefan Allius, rebuild extra/config/conf if it is missing following a make clean Patch from Simon Rowe to try and build asm libm code only when HAS_FPU is set. If you don't have an FPU then usm FPU code isn't going to help much... Final update for 0.9.16 Manditory typo.. Make sure we have __linux__ defined typo fixes For arm use -mcpu for the moment, since it seems to work Update from upstream Don't link to us.kernel.org A powerpc patch from Ronald Wahl: Add missing quotes -Erik Implement sendfile64 -Erik Minor cleanup -Erik As released in uClibc 0.9.16, regex was being compiled without wide char support, even when the rest of uClibc was. This led to anyone using regex segfaulting... -Erik I was an idiot and put _fini into the wrong register. Duh. This patch from David Meggy fixes it... Ronald Wahl writes: I noticed that dlclose() does not work since libraries loaded with dlopen are not marked as "loaded_file". This breaks apache with dynamic modules. I append a small fix against uClibc-0.9.16. Ronald Wahl writes: Fixup minislang link Stefan Allius writes: Patch from Luc Van Oostenryck to fix a buffer overflow in getlogin_r Add in a pread/pwrite test Only build the 64 tests when relevant Doh! I screwed that one all up. Lets try that again... -Erik Fix it for real this time. Remove obsolete files Stefan Allius writes: Cleanup a few structural wierdnesses This draws from an old patch by David Blythe for the now-dead unified syscall interface. I reworked his old patch considerably and cleaned up his version of bits/syscalls.h with some sneaky macro magic. And I implemented a powerpc correct version of pread/pwrite -Erik For now, revert Ronald Wahl's change to dlopen. We need to look into what is breaking dlclose() further... -Erik Update to sync up with glibc 2.3 cut-n-paste typo Stefan Allius writes: I fixed two little bugs in ldso.c: - For LDD support we test the old environment variable LD_TRACE_LOADED_OBJECTS. - Before we init the GOT table of the dynamic loader we have to check, if we have a DT_PLTGOT entry. If DT_PLTGOT was zero we patch somthing in the header of the dynamic loader. This was the cause, why we have to enable the DO_MPROTECT_HACKS option for all targets, to avoid segment faults. Per suggestion from Stefan Allius, change DO_MPROTECT_HACKS to the more clear FORCE_SHAREABLE_TEXT_SEGMENTS. Aidan Van Dyk noticed that _toupper and _tolower were misbehaving. This corrects them, per SuSv3. Silence some whining Implement dynamic atexit handling. Adds a few bytes and a dependancy on malloc (via realloc). -Erik Remove use of $(strip) when no longer needed. Fixup DODEBUG so when debugging is enabled we don't enable all the major optimizations. -Erik Update verbage regarding NIS Patch from Aidan Van Dyk to make _toupper and _tolower work properly, reverting my wrong reading of SuSv3 Patch from Stefan Allius: - Invert all FORCE_SHAREABLE_TEXT_SEGMENTS checks. - Define FORCE_SHAREABLE_TEXT_SEGMENTS in the Makefile, so it can be configured by the config system. - linuxelf.h inspects that we don't combine FORCE_SHAREABLE_TEXT_SEGMENTS and SVR4_BUGCOMPAT - Add a new config option for FORCE_SHAREABLE_TEXT_SEGMENTS Kill SVR4_BUGCOMPAT Rework usershell.c, as the old one was packed full of unhandled failures, returned stack allocated memory, and misbehaved itself in a number of other annoying ways, -Erik Doh! Manuel noticed I'd put the CFLAGS before DODEBUG, killing any chance of actually building with debug symbols. -Erik Act more like the GNU version. Accept multiple args. Accept/ignore the "--" option since we always do that anyways. -Erik Patch from Yoshinori Sato to update the h8300 architecture. Cleanup use of in6addr_loopback and in6addr_any Oops. Doh! As Stefan Allius points out, I forgot to properly review this change. Oops. As Pavel Roskin notes, I forgot to conditionally include the __fsetlocking call in libc/unistd/usershell.c. It should be wrapped and only included if __UCLIBC_HAS_THREADS__ is defined. Use 'install' rather than 'mkdir -p' for target directories. Add $(PREFIX) to avoid leaking things at install time. -Erik Fix the defaults to make them be sane Fixup sysconf to report the correct answer when UCLIBC_DYNAMIC_ATEXIT is enabled. Make support for global constructors and global destructors be configurable, so people who do not need or want ctor/dtor support can disable it and make their binaries a little bit smaller. -Erik Fix compilation on mips Kill a bit of unused cruft Silly me, I forgot to include features.h I forgot to include features.h Spelling fixes -Erik Don't leak outside of the target area when installing things. -Erik Make the arm cpu-specific optimizations work properly Properly allocate memory when size is 0, but so is buf For now, always claim we have exactly one cpu. It should generally be the truth... Fix the other instance of getcwd Override optimization settings when debugging Looks like this is in fact needed to properly debug dynamically linked stuff, so put it back but add a check for NULL Implement the rest of the missing include/net/if.h interfaces -Erik This is based on a patch posted to lkml by Petr Baudis on 23 Nov, which was then considerably hacked up by me. This eliminates the separate lxdialog and instead directly uses the lxdialog internals. This allows 'make menuconfig' to be much faster. -Erik I forgot to kill these files in my last commit. -Erik Change some variable names so we are more consistant with what the linux kernel uses. -Erik Cleanup the case when using the system shared lib loader -Erik Remove a stray ')' Avoid silly namespace pollution Fix broken ignore file Add in a stub libnsl library to make stupid configure scripts (i.e. openssh) do the right thing when used with uClibc's gcc wrapper (which does not currently prevent system libraries from leaking into the link). -Erik Fix typo noticed by V.Radhakrishnan Add portmap and patch from Steven Elling Based on discussions with Stefan Allius, change it so that we always build a crt0.o and a crt1.o. crt1.o will support ctors and dtors if such support is enabled. One more gratuitous toolchain support issue is thereby removed... -Erik It seems SCO puts touch in a wierd place Oops. Patch was vs 5beta. When -shared is specified, meaning they wish to create a shared library, we need to disable adding start files (i.e. crt0) since it isn't supposed to be creating an executable, just a shared lib. -Erik Use crt1.o when ctor/dtor support is enabled Rework things such that staticly linked applications can use dlopen and have it be successful. This required moving some things out of ldso.c into readelflib1.c, and directly including hash.c and readelflib1.c into dlib.c when building the static version of the library. -Erik Move the soft float check Only build the ncurses stuff when it is needed, based on a patch from Stefan Allius (though the extra/config/Makefile rework is mine), -Erik Dop not restrict the IFTODT() and DTTOIF() macros when _DIRENT_HAVE_D_TYPE is not defined. -Erik Patch from Stefan Allius. Only build config stuff when needed. Thanks to Siim Vahtre, add mplayer Be sure we have a crt1.o file. Use the asm version by default. -Erik Rework sparc architecture support so it will compile and run. Seems to be working... -Erik If they call dlopen with anything other than RTLD_LAZY or RTLD_NOW then we need to error out. Lineo has ceased to exist and is no longer a sponsor Disable the __USE_EXTERN_INLINES versions of these headers, which use non-existant glibc internals. Hide unimplemented and legacy ecvt and friends from configure. -Erik mention the uClibc root_fs now available on uclibc.org Patch from Nick Fedchik to support ether_aton Implement lockf64 -Erik Fix warnings Patch from Jay Kulpinski: __decode_dotted() does not count the null terminating byte of a hostname in the DNS response. This causes lookups to fail if the DNS response doesn't compress domain names in the message. Update website dev image blurb Patch from Robert Schwebel -- support ncurses installed in /usr/local Strip off unwanted quotes from ARCH_CFLAGS. Attempt to enforce consistent sort order, 'gcc -print-search-dirs' behavior, etc by forcing the build into the C locale. -Erik Update build rules a bit. fix quoting problems. Update default x86 compiler optimization to not force building i386 opcodes. Remember to also export LC_ALL in addition to setting it. -Erik Only include lockf64 when large file support is enabled, fixing a problem noticed by Jeff Mock. Sorry about that. -Erik Looks like sigaction on arm needs adjustment, so split this into a common header file and a default implementation. Missed an endif Add in arm specific sigaction implementation to fix sa_restorer behavior so it works as expected Update sigaction syscall names to act more like glibc. Fix the x86 sigaction implementation such that gdb can actually debug signal handlers. Gdb behaves much better now, for example, on multi-threaded apps. -Erik Patch from Brett Hunt at micron.com to fixup potential segfaults during 'make menuconfig' Fix indenting. Per patch from Nathan Field at ghs.com, change LINUXTHREADS_PTHREAD_THREADS_MAX to properly point to "__pthread_threads_max". Per patch from Nathan Field at ghs.com, add a couple of variables needed to make gdb happy when debugging threadded apps. Per patch from Nathan Field at ghs.com, fix __pthread_initialize_manager so it locks before calling clone when under a debugger, and unlocks on success or failure of clone when under a debugger. Per patch from Nathan Field at ghs.com, fix the mips __compare_and_swap inline function. Without this fix, pthread_mutex_lock/pthread_mutex_unlock don't work on mips. Just be a bit less different from latest glibc version in comments and in the files where variables live. Update malloc behavior on malloc(0) to be consistant with malloc-930716 behavior, i.e. return a NULL. Kill the needless '#if 1' Rewrite powerpc crt0.S for proper ctor/dtor handling Shuffle two lines so the comment applies to the correct line. simpler method for getting a 'main' reference. Make _init and _fini be weak so people won't need to fix their compilers Making atexit weak does nothing for dynamicly linked apps. And for staticly linked apps it entirely prevents destructors from running unless atexit is called for some other reason. So if they enabled ctor/dtor support we need to have a call to the real atexit for dtors to work properly. If people don't want the extra 4k or so of junk in their static apps, they should leave ctor/dtor support disabled. -Erik Cleanup makefiles and make clean a bit Update a tiny bit Update ignore list Update tests to be somewhat consistant with the rest of the world Shuffle OPTIMIZATION setting a bit Update crt0 for arm to provide the main reference a bit more nicely, and make _init and _fini be weak for people with broken compilers -Erik Hopefully this will work as expected. I have no way to test but this should be correct. Hopefully this is correct Update architecture specific support to consistantly generate a crt0 and crt1 file. Most arches still need to be updated to call __uClibc_start_main() rather than __uClibc_main(). Doh! Fix potential stack corruption caused by dynamic atexit allocating size incorrectly.... -Erik Add FAQ entry for "sh: can't access tty; job control turned off" -Erik Ok, people are probably going to hate me for this... This commit changes the type of 'struct stat' and 'struct stat64' so they use consistant types. I thought it would be smaller to inline since these funcs are small. Well, not inlining saves 300 bytes, so do that instead. -Erik Better stat tests Don't clean config system except on 'make distclean'. Remember to clean locale stuff on 'make clean' Finish up fixing stat and setting various system types. Stupid typo Support having libs in /usr/X11R6/lib by default as well Begin release preparations... A few more needed updates Stick some evil casts in to make sure this works regardless of the underlying data types. Fix powerpc struct kernel_stat types Update the changelog for release Update webpage for release Move some stuff into old-news some minor todo updates This seems to be needed or else apps will blow up. -Erik Fix the 'make release' target Cleaner bah Patch from Stefan Allius to fix the build when large file support is disabled Stefan Allius noticed dlib_pic.o was not using XXFLAGS as it should Add a couple of tests Fix scandir64 to not free the wrong pieces of memory (which could and did cause segfaults) by adjusting the working scandir.c to the the 64 thing. Fix up potential for mismatches between the libc and kernel dirent structures, which could also cause ugly problems. -Erik Create stub crti.o and crtn.o files when UCLIBC_CTOR_DTOR is disabled -Erik The original glibc sysdeps/mips/dl-machine.h source from Kazumoto Kojima was under the LGPL. I noticed Steven J. Hill has accidentally changed the license to be GPL. Per email with him, change it back to LGPL. Patch from Christian Krause: Patch from Christophe Massiot: Per discussion with Nick Fedchik, restore original LGPL licensing to libc/inet/ether_addr.c Patch from Marshall M. Midden @ brecis.com: pipe.c for mips was broken with freeswan. No error checking. Fix copyright heh Oops. I'd left an extra invocation of sigaction in there... Fixup compile on 2.2.x kernels when UCLIBC_HAS_LFS is enabled Patch from Stefan Allius to fix a compiler warning Patch from Stefan Allius to make adding libgcc functions to the library an option, to avoid the possibility of adding non PIC code into the shared PIC uClibc library, thereby making the .text segment unshareable. mention penguru Fixup handling of the .note.ABI-tag section so that it is ARM only, and so it actually works as intended allowing binaries on ARM to be debugged. -Erik Fix a compile error Fix a warning Mention the dev systems have been updated A few minor little changes We need to have the size of struct dirent equal to the size of struct dirent64 so when _FILE_OFFSET_BITS=64 (such that we transparently change 32bit into 64 bit interfaces), we will not lose an unsigned char from d_name which silently becomes the d_type field instead. oops. -Erik Per suggestion from Peter Lassahn, fix the install_dev target Use http not ftp Somewhat pointless naming pedantry Bump version number Update changelog Eliminate a needless extern update website for release Remove now obsolete note about dirent Some minor doc updates Minor update regarding binutils Update to note dev system Move dev system comment Oops. Point to .18 not .17 Fix a _ton_ of system call user type/kernel type translation problems, causing user space to get scrambled hosed up results. -Erik Don't just tune, use -march which implies -mcpu as well Add missing ';'s so powerpc will compile Fixup powerpc syscalls to eliminate warnings with gcc-3.2, and fix some other minor warnings. Patch from Stefan Allius: Patch from Stefan Allius: Patch from Stefan Allius Fixup bui Mention latest update Fixup ioctl so we can special case powerpc silliness Some stuff I forgot to check in about a month ago... -Erik Fixup some small issues that show up when large file support is disabled Add a toolchain section. Mention Steven J. Hill's mips RPMs. Add a bunch of additional early debugg messages into the shared lib loader to make it more obvious what is wrong when things puke early on in the process. -Erik Fixup a really stupid and terribly obvious bug that was causing the shared lib loader on mips to puke... -Erik Prefer mmap2 for mips when available. Fix the mmap test. -Erik Patch from David Airlie to fix handling of ctor/dtor stuff when used in combination with and w/o both the nostdinc and nostdlib options. Fix a silly bug Major update for pthreads, based in large part on improvements from glibc 2.3. This should make threads much more efficient. -Erik Fixup mips pthreads Fix a potential compile error Fix the shared library loader so we can properly debug things like pthreads. Mips gdb support for pthreads and similar complex stuff is broken, but then it couldn't have worked before either... -Erik doh. I forgot mips can't talk to globals that early on in the process. Fix that up too. -Erik doh. I forgot mips can't talk to globals that early on in the process. Fix that up too. Use a funky version in a probably vein attempt at preventing gdb from dlopen()'ing glibc's libthread_db library... Patch from Jeffrey Damick: Teach ldd to act just the glibc provided one (relying on the shared lib loader to do the work) when it is possible to do so, and only go poking about through the ELF headers when that fails so we can still use 'ldd' on cross compiled stuff. -Erik Add missing alias __modify_ldt cut-n-paste strikes again begin preparing for release Fix location of cvs Update version Updates for release Initial effort at adding profiling support. Fix grammar Fix compile when profiling is disabled Teach ldd to be a bit more helpful by telling you specifically what the problem library is that is linked vs glibc. -Erik Patch from Stefan Allius to make ldd.c compile under Solaris Patch from Stefan Allius adding the function 'thread_self_stack' from glibc 2.3 that is needed for pthreads to compile for SuperH. Seperate pthread debugging from uClibc debugging. They are used for different things. Default to using fork() for vfork() when no arch specific implementation of vfork is present. The vfork system call on powerpc seems to be completely broken. Use fork instead, per glibc behavior. Patch from Stefan Allius: Patch from Konrad Eisele to omit -Wl,--dynamic-linker from the gcc wrapper when not building with shared library support. Patch from Konrad Eisele to add include/asm-generic since, at least on sparc, this is needed by some of the include/asm files Update website Patch from Stefan Allius to finish off the last required bits for gmon profiling support for the SuperH target. Make profiling on arm work Finish off gmon based profiling for powerpc For now, leave mmap on mips using mmap1, since mmap2 seems to have 'issues' (i.e. it doesn't work 100% properly). -Erik Make the text a bit more clear /me needs to learn to proofread more random changes Fixup ldd handling of multiple files Patch from Stefan Allius: fix a couple of gcc 3.3 compiler warnings in gmon.c Patch from Stefan Allius: Patch from Stefan Allius remove a leftover debug printf Patch from Jordan Crouse to avoid potential rendering problems Minor cleanup to better sync with glibc 2.3 Make it so debugging pthreads works, even with DODEBUG turned off -Erik sjhill needs to buy donuts for everyone resync with glibc 2.3 Oops. Don't call strip twice Avoid errors with buggy preprocessors Patch from Liam Girdwood to fix mips profiling when using newer gcc versions. Konrad Taro Eisele noticed the sparc struct stat was broken. Fix it. Patch from Marshall M. Midden: Fix SIGTRAP handling on arm. The defination of struct ucontext, which was copied from glibc, is wrong. So fix it. -Erik Thierry De Corte notices that when UCLIBC_HAS_FLOAT is disabled, we must also disable drand48, drand48_r, erand48, and erand48_r since they use floats. Comment on glibc's MALLOC_CHECK_ support. uClibc 0.9.19 has a bug in globfree(). If the previous call to glob(...,pglob) used the GLOB_DOOFFS flag to reserve the first pglob->gl_offs slots of pglob->gl_pathv, globfree(pglob) would attempt to free the objects pointed to by those slots. If those objects were not on the heap, the system would crash. Cope with autoconf's broken AC_FUNC_MALLOC macro, which redefines malloc as rpl_malloc if it does not detect glibc style returning-a-valid-pointer-for-malloc(0) behavior. This wrapper calls malloc() as usual, but if N is zero, we allocate and return a 1-byte block instead.... sigh... Change 'N' to '__size' to avoid conflicts with common #define of N grr. It's a void *, not a char *. Accomodate building under cygwin Allow gcc to move/update by detecting where needed files are should they move/disappear from the expected location. -Erik Eviscerate stropts.h so configure scripts won't try to use STREAMS garbage. uClibc does not support STREAMS in any way whatsoever. -Erik Enable ADD_LIBGCC_FUNCTIONS by default on arm In a number of places we erroneously used tests such as '#ifdef PIC' when we should instead have been testing for '#ifdef __PIC__'. This resulted in NON-PIC code getting mixed into the shared library. Oops!!! -Erik Clone still had a few little PIC problems.... Patch from Peter S. Mazinger to fix some leftover problems from converting "PIC" to "__PIC__" Fix broken Kill the runtime fallback to fork and make it be compile time We do not provide getfsent and friends, so remove this header file, to prevent stupid configure scripts from getting confused. Patch from Peter S. Mazinger to make the get-needed-libgcc-objects script work with newer binutils versions. Fix arm syscall implementation so it does not blow chunks with gcc 3.3 -Erik Marshall M. Midden at brecis.com writes: The gnu ld and binutils for mips has a bug with relocation. Fix mips so it compiles with gcc 3.3 Set the default thread stack size to 16k for mmu-less systems. -Erik As suggested by Marshall M. Midden at brecis, use -mno-split-addresses instead for mips, which should be a bit faster and will be safer too. The mere presence of stropts.h causes many configure scripts to erroneously believe that uClibc supports STREAMS. Well, we don't. So I am hereby removing this header file, since it was empty anyways. Applications that depend on stropts.h being present, but do not depend on its contents, are broken anyways. -Erik Bump version number in preparation for a release Comment out the rpl_malloc workaround. It was a good idea, but it violates namespace guarantees and conflicts with other programs that have used the AC_FUNC_MALLOC autoconf macro properly. Implement syscall() for powerpc. Fixup syscall code so it compiles properly with gcc 3.3. -Erik Don't segfault when given things other than a regular file. -Erik Fix a segfault when used on a library w/o an INTERP program header. For some strange reason, davidm put this file in the wrong spot. So put it where it is supposed to be. -Erik As noted by Peter S. Mazinger Coldfire patch from Bernardo Innocenti When compiling with -O0, linuxthreads does not compile. So add a local override changing -O0 to -O1 only for that directory. Patch from Ronald Wahl fixing an IPV6 specific problem with getaddrinfo(). Be extra careful to memset the correct size, not the size of some random pointer. Fix printing of '0x0x' in ldd output. Simplify discrimination of libname, so doing things like dlopen("./libfoo.so",RTLD_NOW) with a leading "./" in the path will work as expected. -Erik Make login actually write out utmp and wtmp junk (even though such things are completly unreliable crap) Rename the very badly named 'UCLIBC_GCC' to 'UCLIBC_ENV' and implement 'UCLIBC_CC', which does this: Make indenting be consistant Fix indenting for real this time. Several more cleanups Add in ceilf() and floorf() since XFree86 wants them... Per a patch from Rob McMullen, add getprotoent_r, getprotobyname_r, and getprotobynumber_r Add missing madvise syscall Mention that the common mmap64 is a stub and must be overridden on a per arch basis using platform specific code Actually, some arches do support _syscall6, so implement a generic version for them... -Erik oops. Fix the name so it is "mmap64", not "__mmap64" add mmap64 for i386 Implement mmap64 for arm Cleanup a couple of ugly bits Do not let isatty mess up errno Add config option to enable 'struct tm' timezone extension fields Fixup errno handling -Erik Yet more cleanup for the reentrant pwd/grp functions so they should now actually be doing the right thing whitespace and debug updates Revenge of the Typo Run dlopened ctors and dtors in the correct order oops Add a test which shows off the broken spots in our dlopen implementation ret could have been used uninitialized in one case Fix a couple of typos Patch from Pavel Roskin to fixup toplevel help text Per suggestion from Stuart Hughes, allow uClibc to re-install headers on a system where they have previously been installed.

Doing an search and replace on CFLAGS can prove dangerous. We don't do -O0 by default anyways, so leave this disabled for now. Remove the arch specific shm.h and use the fixed up common one which now uses the kernel structs -Erik Update licensing discussion Update inet_aton() to support an undocumented feature of inet_aton, per UNIX Network Programming, Volume 1, second edition: For sparc, powerpc, mips, and alpha we should also use the common ipc.h header and struct definitions. -Erik Merge/rework config system per the latest from linux-2.6.0-test2 -Erik Shuffle options around a bit Looks like I missed a spot Zou WeiJun noticed a type breaking the stime syscall -Erik Patch from David Wuertele to prevent "conflicts with new declaration with C linkage" problems with C++ Begin documenting differences between uClibc and SuSv3 -Erik Add support for personality(), prctl(), ustat(), and ulimit() syscalls, which had managed to stay unimplemented thus far. -Erik Add in a MALLOC_GLIBC_COMPAT option to let people decide if they want glibc style malloc(0) behavior Add support for the ulimit syscall Update likely() to cope with truth values other than 1 An even simpler likely silly me, thats not going to work. also carefully booleanize the false value Fixup centering so the site does not look like crap in IE Patch from Paul Mundt adding uClibc sh64 support: Use the common version for bits/sem.h. Fixup the types to match the kernel type exactly. Cleanup arm architecture optimizations and add big endian arm as well. Phase one of my evil plan to clean up ld.so... Cool. Found most of the problem. Turns out we were inadvertanly loading some libraries multiple times, wasting memory and causing different libraries to use different symbol sets, some of which were not properly resolved. More routine cleanup I just realized we need global symbol resolution for everything in a chain of dependent libraries or libraries that depend on other shared libraries will not work! Update the tests a little bit ignore unwanted stuff Revert this change for now. Be sure to remove the old ldso.h, since it will screw things up badly if still present... Add missing semicolons Remove some mips specific hacks that are no longer needed, and actively break things, now that I have cleaned up the code to be a bit less horribly messy. With this, the shared lib loader works on mips once again. -Erik Patch from Atsushi Nemoto, who writes: mention ucdot.org Link update Make the mips ld.so debug noise somewhat useful, and less gratuitously different than all other arches. -Erik Avoid gratuitous conflicts when used with kernel headers Don't use linux/sysctl.h and instead locally define struct __sysctl_args. conditionally add wordexp, in this case ripped from glibc. I hate to add this stuff, but it is specified by SuSv3... Reluctantly add wordexp() here is (I hope) a better way to handle this one. I regularly build debug versions of uClibc with -O0, but libpthread/linuxthreads/spinlock.c will not compile without at least -O1 optimization... Remove comments about wordexp. Add a couple of things... And check that cvs commit diffs are working again... Weed out duplicates before trying to load libraries.... Delayed checking for duplicates and returning an alias if an existing lib is already loaded is still correct for the dlopen case. Greg Nutt writes: Atsushi Nemoto writes: Rob Landley writes: Remove a bunch of guessing about the location of the kernel headers.

Make it easier to disable lib debugging (mainly for when testing with glibc). Fix a problem with dtors/dtors. delete some garbage, cleanup duplicate handling cleanup/simplify duplicate handling. Let "$KERNEL_SOURCE/include/asm" be either a link or a directory. Minor cosmetic cleanups to avoid getting spurious bug reports. mjn3 noticed we were missing seed48, which was odd since we had all the other *48 random functions. Add support for ftw and nftw Bump version number in preparation for a release Remove ftw and nftw as exceptions, add getgrgid_r and getgrnam_r Let people enable ftw, make glob an option, add a new "Big and Tall" top level config menu. Fix the bugs I stupidly added Remove more headers when options are disabled Add more pretty comments Be more clear fixup ftw and ftw64. Unfortunately, adding ftw64 doubles the size... :-( oops. ftw would blow chunks if UCLIBC_HAS_LFS was disabled. Running ltp 20030905 showed that tcsendbreak was broken. This fixes it. Fix errno values. Fix MALLOC_GLIBC_COMPAT handling in malloc/malloc.c, which was reversed. Provide more consistancy between implementations. Handle it when people do stupid things like malloc(-1); Fix numerous problems with both getcwd implementations. -Erik Add an implementation of profil(), based on the version from glibc, with several changes for use in uClibc. add missing prototype 'extern inline' doesn't work... Use 'static inline' Fix some more problems found by the ltp Some updates from glibc. mjn3 reports this fixes profiling on i386, at least, so seems like a good thing. A few minor syscall cleanups More FAQ updates mjn3 pointed out that my brain was not in gear.... Be certain the config system binaries are current Fixup build problem on powerpc Use __libc_fork for the uClinux fork stub Fix a trivial compile problem Fix broken test Oops! I broke pread on mips with my last update. This fixes it again so it both compiles and works, -Erik Force enable ADD_LIBGCC_FUNCTIONS on arm Add in several config system updates for locale support.

Apply a trivial patch that doesn't change anything, but which is alledged to workaround a toolchain specifi bug for the e1. Patch from Atsushi Nemoto (with some additions): Atsushi Nemoto writes: When someone would dlopen a shared lib that was already opened, we would try to re-fixup the lib's relocations with rather horrible results. So fix that by checking the the dlopened lib has already had its init functions called, which will never be the case for newly loaded libs, and skip the rest in that case. move the test for loading the wrong C library into the _dl_check_if_named_library_is_loaded function Patch from Rob McMullen: Implement getgrgid_r and getgrnam_r. Rework group handling code to be fully reentrant, since there was still a shared static value. indent stuff, Remove some stuff that is now done We do not provide gmtime(), so disable the prototype to prevent confusing autoconf These are wanted by net-tools I forgot to remove this Sigh. It seems that csh wants glob_pattern_p(), we need to export it, Don't make two copies Always build and install ldconfig Fix an ldd bug, more ldconfig cleanup Patch from Peter Kjellerstedt: sigh. the warn funcs seem to be broken. Use local versions till I can straighten that out. Enable full debug support for ld-uClibc and libdl Doh!

Ugh. This fixes that as well... -Erik Merge some newer/updated bits from the glibc elf.h Patch from Peter S. Mazinger: Fix a stupid bug that caused uClibc to never provide the correct fpu_control.h header file, since the correct arch specific one was always later overwritten by the generic one. oops. -Erik Doh! In include/bits/uClibc_config.h when we define things, we appropriately prepend "__". Unfortunately, when we #undef things, we do not prepend the "__". This results in collateral damage to unsuspecting applications as we undefine random unrelated macros. Oops. Those crazy binutils folks changed their abi. Add this so older apps can cope gracefully. It seems we need to also define SI_LOAD_SHIFT since that was also exported by the Linux kernel.h header that we do not include.

Better utilize the Kconfig language which should simplify enabling arbitrary architectures. -Erik Kill off the gcc wrapper. It has served us well, but there comes a time when 90% of correct is simply not good enough. Some people will not be very happy about the decision to kill the wrapper toolchain. Sorry, but a real toolchain is the One True Way(tm). -Erik Naming things this way will be much easier to deal with Peter S. Mazinger writes: As Peter S.

This will need further work later on, but should do the job for the time being, Rework the powerpc lib loader to better match the other architectures tiny cleanup Fix a misnamed array Add some initial x86 string optimizations. These make no attempt to use nifty things like mmx/3dnow/etc. These are not inline, and will therefore not be as fast as modifying the headers to use inlines (and cannot therefore do tricky things when dealing with const memory).

The perl test suite would alloc a larger buffer and try again until all memory was exhausted. When we get a read error, or EOF, it means we didn't get what we wanted, and so we should return an error. Doing so fixes the failing perl 5.8.2 test. -Erik Update and restore malloc-simple. Slow as molasses, but trivially simple and releases memory immediately when asked to do so. -Erik Rework malloc. The new default implementation is based on dlmalloc from Doug Lea. It is about 2x faster than the old malloc-930716, and behave itself much better -- it will properly release memory back to the system, and it uses a combination of brk() for small allocations and mmap() for larger allocations. -Erik Make sleep behave itself properly inthe presence of SIGCHLD Fix the manditory typo in my last minute untested fix. -Erik Add extra checks for sigprocmask and rt_sigprocmask syscalls. The rt_sigprocmask syscall has broken error handling in 2.4.x kernels, while the sigprocmask syscall appears to get things right. Regardless we should be extra careful, and add these checks.

It turns out that the problem that required us to use --enable-sjlj-exceptions was specific to gcc 3.3.3. Later toolchains fixed the regressions; thus, we do not need to worry about this TODO item anymore. The default static buffer sizes are too small to handle the 8 entries returned by 'nslookup www.yahoo.com' and 'nslookup mail.hotmail.com', and thus we currently return ERANGE when trying to lookup some of the most popular hosts on the planet.

This is now done in ldso.c Oops, forgot to remove unused variable. Move the app specific stuff from dl-startup.c to ldso.c. Move "debug_addr" ptr from dl-startup.c to ldso.c Remove poor man's malloc. Not needed anymore. Accunt for ELF_MACHINE_PLTREL_OVERLAP when relocating ldso. Hopefully fix Laszlo and Jacobs dlopen problem. Patch from Stefan Allius: Remove unused function parameter in ldso.

You may luck at the patch for the powerpc/elfinterp.c, where I change the paramter of a dl_dprintf statement. Now we use the same parameters than for the relocation copy." Added test for RTLD_GLOBAL flag in _dl_find_hash(). Fixed a bug in libdl.c where the RTLD_GLOBAL was assigned wronly. Let ldso find libc's malloc function and set _dl_malloc_function. This removes some crap in libdl.c(and future libs which needs to access ldso functions). What do you think? As Mike Frysinger notes, this code is still needed. I misread this code and removed it, sorry. Forgot to commit this file. Patch from Stefan Allius. #include "dl-startup.c into ldso.c, making ldso one compilation unit. Now all functions and vaiables can be made static to reduce relocs. Basicly, all variables should be merged into one struct variable and then export that struct. Exported functions should be exported as functions pointers in the above struct. This will reduce the number of relocs inside ldso to a handful. Preliminary PIE support for powerpc, i386 was used as template. Requested by Peter Mazinger. Testing wanted. Typo fix from Peter Mazinger. Remove unused variables. From Peter Mazinger. First attempt to fix the INIT/FINI ordering. Fingers crossed :) Second attempt to fix the INIT/FINI order. This time I think I got it right :) This needs testing with apps that have complex dependencies. Don't allow undefined global symbols to pass(all archs needs fixing). If you are using buildroot and soft floating point, you may have to rebuild the libm.so library, copy it to staging_dir/lib and rebuild your application. Don't allow undefined global symbols to pass(all archs needs fixing, but powerpc). If you are using buildroot and soft floating point, you may have to rebuild the libm.so library, copy it to staging_dir/lib and rebuild your application. Bugfix: Add r_addend to final address. The r_addend is mostly zero but can be nonzero for JMP relocs as well. All Rela arches need to do this, test and send a patch :) Formatting cleanups from Peter Kellerstedt. Added back dl_iterate_phdr in ldso(with some small changes). Someone needs to test if it works to build and run gcj. Make powerpc look more like the other archs. Don't allow undefined global symbols to pass. Move COPY relocs back to _dl_do_reloc(). Make do_rem() safe. From Peter Kjellerstedt. White space and printouts cleanup. From Peter Kjellerstedt.

Peter Mazinger writes: The attached patch generalizes the use of PIE (all archs are brought in sync that use/mention it: x86/ppc/frv) and makes use of it building the target utils. hmm, somehow cvs lost this file in the previous commit. unmap ld.so.cache when dlopen() returns. - Remove dynamic_size from struct elf_resolve. - Replace all open coded dynamic handling with a function. Reduces size. - Fold special MIPS dynamic code into the dynamic_info item. - Add RELRO support. - Support linking with "-z now". - prepare for DT_RELACOUNT/DT_RELCOUNT optimization. - Add -z now to ld.so linking, this is what ld.so does anyway so let the linker know that. Add RTLD_LOCAL support for dlopened libs. Reported by Andrew de Quincey, who has been most helpful getting this sorted out, thanks. Thanks also to Peter Mazinger who did alot of testing. Add BIND NOW support to MIPS. Make __builtin_return_address() return NULL at top of stack frame. This will make backtracing possible. Oops, remove extra sigaddset() call. Don't know how that one got there. Sync with latest GLIBC. Fix death event reporting properly. Now GDB is happy and death events are reported as [Thread 5126 (LWP 192) exited] without GDB bailing out. Add THREAD_SELF definition to PPC. This should make threads on PPC a bit faster. Use DT_RELCONT_IDX to optimize the relocation of R_PPC_RELATIVE relocs. All RELA arches can probably copy this. REL archs will have to delete the "+ rpnt->r_addend" from the loop. Force suid apps to do unlazy binding of the PLT relocs. See http://bugs.gentoo.org/show_bug.cgi?id=71609 for more details. Reported by Peter Mazinger. Generalize optimized relative reloc procesing. Add elf_machine_dynamic() and elf_machine_load_address() for all archs. elf_machine_dynamic() replaces the #ifdef mess to get at the GOT. elf_machine_load_address() is needed to execute ldso directly, this is not complete yet. Simplify PT_INTERP handling. Add prototype for _dl_boot() Oops, fix typo. Same typo here. Fix MIPS initial GOT relocation. Add _dl_boot() prototype. General arch cleanup and prepare support for standalone execution of ldso. Added new asm for MIPS to be tested. All arches should retest. Fix ldso for MIPS. Forgot to commit the arch cleanup changes to m68k Remove dead code. Move ldso FINI handling into _dl_fini(). Add #ifndef _DL_DO_FINI_IN_LIBC around registering _dl_fini with atexit(). This is a preparation to move the FINI handling to libc. Prepare for moving ldso FINI handling into libc. #define _DL_DO_FINI_IN_LIBC to enable(the arch specific part needs to be in place first). Prepare for moving ldso FINI handling to libc by passing _dl_fini. This should not break ABI. Minor cleanup as well. Pass _dl_fini function ptr to __uClibc_start_main(). Prepare for moving ldso FINI handling to libc by passing _dl_fini. This should not break ABI. Minor cleanup as well. Pass _dl_fini function ptr to __uClibc_start_main(). Moved the addition of load address from the fast path where possible. This will also make ldso smaller. However the patch touches all archs and I have only tested PPC and x86. Optimize _dl_elf_hash(), both smaller and faster. Mostly taken from glibc. Prepare PowerPC some more for standalone exection of ldso. Note that every arch that wants to support standalone execution needs to align its stack pointer in crtX since ldso will adjust the stack pointer when adjusting argc and argv in standalone mode. Remove __FORCE_SHAREABLE_TEXT_SEGMENTS__ hack from ldso itself. Fix bug 214, reported by aurel. This is a major update that possibly break other apps. Please test. Send a LD_DEBUG=1 log if there is a problem. Cleanup library loading. Fix dlopen to handle circular dependency libs. Wouldn't surprise me if something else broke. I hate libdl :( Fix bug 222: Move all archs to newer __IPC_64 interface for {msg,sem,shm}ctl syscalls. This won't work on 2.2 kernels(I think). Hopefully fix the problem reported by Peter Mazinger, see http://uclibc.org/lists/uclibc/2005-May/011667.html for details. Not tested by me but I am sure Peter will :) SHMLBA is now defined by arch dependent bits/shm.h file so remove this one. MIPS is the only one defining SHMLBA differently. Fix debug macros. Pass main function ptr from crt1 to __uClibc_start_main. Kill old crt0/__uClibc_main. Update PowerPC to new ABI. Enable new FINI processing. ldso now passes a FINI function ptr to crt. Only PowerPC and x86 support this currently. Adapt startup code in x86 and PPC to almost match glibc. _init vs. __libc_csu_init and _fini vs. __libc_csu_fini remains to do. Prepare for standalone execution of ldso. Fix "off by one" bug. Removed -z defs as a more general solution is in the works. Add PIE support to ARM. From Peter Mazinger Fix PPC wrt new __uClibc_start_main. Adapt x86 to new __uClibc_start_main. Clean it up a little. Pass the aligned stack ptr, not the unaligned. Add back .size for _start Add back .size for __start Add patch at bugs 274. From Peter Manzinger. I added, then removed and now I add this again :). Hopefully I got it rigth this time. gcc says spinlock.c:35: warning: matching constraint does not allow a register fix warnings like td_thr_tls_get_addr.c:30: warning: `__used__' attribute ignored Filter out any -z defs since this lib will have undefined symbols that are in gdb. Add Peter Mazinger fini/crt compat patch. Select DL_FINI_CRT_COMPAT to be able to run apps built with 0.9.27. This also renames __uClibc_start_main to __uClibc_main. This compat option should be removed some time after 0.9.28 is released. Fix bug 60 Initial support for both RUNPATH support. RPATH sematics changed to match RUNPATH. Only difference is that RPATH is searched before LD_LIBRARY_PATH and RUNPATH after. This is not complete but better than the current mess(I think). Add debug printout of RTLD_GLOBAL and RTLD_NOW flag. Remove TEXTREL relocations for ARM. Hide __syscall_error from outside libc. From Peter Mazinger. Fic gcc 4.0 compilation. Still no confimation that this works on gcc 4.0 but I don't want to wait anymore. Hopefully fix PIE apps. Change L_Scrt1 to __PIC__ Change L_Scrt1 to __PIC__ Delete old stuff. Change L_Scrt1 to __PIC__ and delete old crt0.S stack_end in __uClibc_main must point to where argc is. Oops. Add __libc_stack_end to ld.so. The libc.a version remains to do. sjhill, feel free to comment :) Minor cleanup. declare init/fini as weak if __UCLIBC_CTOR_DTOR__ is turned off Add __libc_stack_end to libc. Oops, fix link fail. Quick and dirty hack to prevent ld.so from beeing loaded twice. Bug exposed by the new __libc_stack_end feature in libc.so. Fix bug 358 by protecting _dl_symbol_tables as suggested. Add missing #include <bits/wordsize.h> and change __kernel_time to __time. Minior WS touchup also. s/__kernel_time_t/__time_t Add dependency on ld-uClibc.so.0 for libdl.so. Remove __attribute__ ((__weak__)) from imported ld-uClibc.so.0 symbols. Remove hardcoded ld-uClibc.so.0 name in ldso. Remove SYSTEM_LDSO option since it no longer works. Removed hardcoded ld-uClibc.so.0 in uClibc. From Peter Mazinger. Add utils in make clean rule. From paravoid. Fix bug 387, missing _dl_progname for static apps. Make uClibc vfork() use kernels vfork() instead of fork(). Hmm, things broke with vapiers update. Lets make it compile and let vapier worry about the rest :) Frank Mehnert writes: I use an implementation for malloc()/free() which is sensible about using data after freed. In libdl.c, rpnt1->next->next is accessed after rpnt1->next is freed. Attached patch fixes that problem. asierllano writes in bug 370: The gcc compiler has deprecated the type __uint128 for 32-bits platforms. Due to the fact that this type was introduced in gcc-3.1 it is better to drop its use. (glibc has the same problem and uses this same solution). Change to glibc way of defining syscalls. This should make PPC compile with gcc 4.0/4.1 Add atomic support for PPC. Merge glibc bits/atomic.h powerpc32/bits/atomic.h powerpc64/bits/atomic.h into one file Fix bug 430 and reduce ldso size with 1KB :). Not sure if I need to use fstat64, but I am sure someone will tell me. Remove unused function. Fix bug 370. Make powerpc use sys/syscall.h, instead of defining its own syscalls. forgot MMAP_HAS_6_ARGS __set_errno must be redefined after #include "sys/syscall.h". syscall.h should not have it's own version of __set_errno, instead syscall.h should include errno.h(see powerpc) since errno handling depends on threads/no threads. Hopefully fix the bug Oleg reported in http://uclibc.org/lists/uclibc/2005-October/012809.html This will only fix powerpc. Should be easy to fix the other arches. psm missed a spot :) Don't need this debug check anymore. Fix static apps on linux 2.6. Linux clobbers r7 in 2.6, so use r3 instead to pass _dl_fini. Support SecurePLTs for PowerPC. You need a toolchain that supports config option --enable-secureplt. The assembler must also supports R_PPC_REL16* relocations. gcc 4.1.1 and binutils 2.17 is known to do this. Joseph S. Myers writes: Aurelien Jacobs writes: Fix SEGV for static builds in exit() path.

Now Test.mak includes toplevel Rules.mak so if DO_ASSERT is not set then -DNDEBUG is added to CFLAGS so we need to get the seeko() calls out of the assert otherwise they get cancelled when NDEBUG is defined. Sync kernel_stat64 with kernel. Thanks to Daniel Jacobowitz for hints. Using local variable 'result' caused problems with lseek64 syscall failing with gcc 4.2. Renaming to make it a bit uncommon name. Remove preprocessor warning due to missing definition of USE_TLS Fix arm mmap when using mmap2 syscall. Fixes bug #1303 Do not return error when fprintf returns 0 in addmntent(). fprintf is considered failing if the return is less than 0 Fix mmap64 undefined on arm oabi with pure thumb1 patchset. Thanks Tobias Poschwatta Cleanup INTERNAL_SYSCALL macros for ARM. Wire up vmsplice, splice and tee for arm. Fix bug 4994 hangs on read(). I have tested the patch extensibly on ARM/LT.old. Thank you Chase Douglas for reporting it and for the patch. Use C implementation of strncmp. Add a new strncmp testcase. Remove __NTH from the declation. get rid of __libc_* symbols. Some whitespace cleanups. These defines needs to be considered after recent linux kernel combined i386 and x86_64 into x86 Merge some pre-work from branch, needed by NPTL. Make TLS configure time variable. Enable it along with NPTL. Define creat in an independent file Update copyright header.

Fixed Makefile for m68k. UnDOSified file and added assert when debugging. The files unified_syscall_{ARCH}.h are not auto-generated while others are. Work around str_syscalls.sh not having execute perms. Should fix in cvs. How? Add missing symbol for ipc and ignore commented syscall lines. This is _NOT_ an auto-generated file. Added #include <wait.h> for getrusage. Increase BUFSIZ to 512 to avoid bug in busybox tar. Set dynamic linker used to /lib/ld-linux.so.1. Changeable in Makefile. Added missing _SC_2_FORT_RUN case. Fixed _SC_ATEXIT_MAX to match atexit.c. Fix static buffer used initialization for FIXED_BUFFERS > 2. Note about need to match _SC_ATEXIT_MAX. Minor macro name change. Hopefully fix the size/type errors when doing a shared lib. Fixed stderr initialization bug (mine). Clean up atexit.c; make sure sysconf and atexit agree; link in ref'd libgcc.a objects with shared uClibc; allow disabling long long support. Enable auto-generation of a size-optimized sysconf function (saves .5k on i386). Fixed (hopefully) 0-pad bug in printf. Added asprintf function. Reworked the *s*printf functions to no longer use a static fake file. Really fixed 0-pad bug this time. ;-) Code-size reductions if sizeof(int) and sizeof(long) equal. printf # flag now works for b (binary) specifier. Reduced code size; fixed ANSI bug for day -- 5 not 05; mode days and mons const. Hide some unnecessary output. Check cvs logging script. Fix a couple of bugs in printf. Add floating pt output for doubles. Yeah! Modified stdio/Makefile to build printf.c according to Config values for HAS_FLOATS and HAS_LONG_LONG. Added some notes. Removed some dead code. Fix the ordering of the args to the compare function. Add #define to handle new ptrace support. Clean up lots of warnings. Hack DYNAMIC_LINKER setting for now. Define __USE_GNU as glibc does. Fix broken prototype. Fix stdin/stdout/stderr (that I broke) and add vdprintf prototype. Handle definition of struct timespec. Add missing header file. Comment out for now. Not used and was causing an error. Add tsearch functions from libc-5.3.12. Fix stdin/stdout/stderr for now. Add vdprintf function. Note: will be rewritten to check if file descriptor has an associated FILE to avoid bad interactions with buffered output, but needed for busybox right now and that implementation has the same bug. Add bdflush. I guess we always need timespec... And apparently some things include sys/time.h instead of time.h in uClibc... Fix LIBC rule. (cut-and-paste user bug...) Fix problems with test wrapper and test compiler selection. Revert to standard handling of _exit syscall in unified syscall case on i386. Create __uClibc_main to handle what can be done in C instead of each arch's respective crt0.S. crt0.S should now only be responsible for setting things up to call __uClibc_main(argc, argv, envp), which will do any other necessary setup (setting global __environ, stdio init, etc), call main, and exit. This should ease both maintainance and porting. Lots of stdio cleanups. Several bug fixes, addition of a number of functions to supplement macros in stdio.h, change perror to use stdio package instead of "write". Also add back in weak stdio initialization for static lib case. Remove redundant old isatty.c since newer termios supplies one. Make sure errno is 0 before we call main (may have been set while initializing). Have isatty call ioctl directly rather than tcgetattr; especially since any program using stdio will call isatty during initialization. Fix a couple of bugs in _fopen and fclose, plus change a few internals. stdio mostly rewritten... passes lots of tests now. printf now supports long double, plus some bug fixes. Fix a buglet regarding floating point output for ?nprintf functions. Added __strtok_r function. Change strtok to a wrapper around __strtok_r and add a weak alias of __strtok_r for strtok_r since optional. Also reduced code size. Stupid buglet fix. Don't trash FILE bufstart if buffer allocation fails. Fix a couple of bugs: check mode is legal; open file and check success before calling vfork. Fixed vfork on i386. Reduced size of __uClibc_syscall. Patch from Michael Shmulevich (michaels(a)jungo.com) -- functions were not declared type function. Fix unified syscall stuff for changed ?stat. Move fork to syscalls.c wrapped with a check for NO_MMU of course. Move fork to common/syscalls (with NO_MMU check). Add Makefile to sparc so make clean works. Fix a bad assertion test. Add some missing network functionality; grabbed from libc-5.3.12. Define h_errno to be errno for now. Hack long long support into scanf. For now, will fail for unsigned long longs that are greater that long long max, but works well enough to support interface in busybox. Just a temporary measure until scanf.c is rewritten. Delete a stray character that hopped into the file... New version of scanf, with floating point support. Fix bug with %c... takes care of bug reported with busybox ps. Fix fdopen mode-compatibility test and errno setting. Part of the ctype locale support. Added Vladimir's ctype locale support. Make Config setting visible in features.h. Reworked build of shared lib as suggested by Magick <magick(a)dds.nl>. Part of the shared lib build rework. Test for Config features using features.h. Since Erik apparently wants def/undef vs def 1/0... Small change from Vladimir. Put weak symbols where they can find what they are aliasing. Clean up strcspn.c Fix longjmp on i386. Also adds siglongjmp. Add missed dependency. TODO: Should build gen_sysconf when cross-compiling. Add some missing headers needed by ld.so-1.9.11. Bug fix from Peter Kjellerstedt <Peter.Kjellerstedt(a)axis.com>. Add missing function sigfillset. Fix dynamic linking bug. If you need -ldl, you must explicitly add the library (path and version!!!) to the args instead. For example, add /lib/libdl.so.1 if DYNAMIC_LINKER is /lib/ld-linux.so.1. Change shared lib name. Update install_new target in Makefile. Update the gcc wrapper. Changes described in the notes at the top of the file. A couple of printf fixes from Johan Adolfsson (johan.adolfsson(a)axis.com). Fix fwrite return value bug reported by Matthias Kilian <kili(a)outback.escape.de>. Fix comment for #endif to remove warnings. Add comment about scanf pushback behavior and glibc difference. Proper prototype for mtherr, although this should probably be made an internal/hidden function (and merror and internal/hidden variable). Add poll.h header. Added file for non-Cephes double routines; currently only fmod and modf. Remove dead code. Minor fix. Revert behavior to either INSTALL_DIR or BUILD_DIR but not both. Also, if using BUILD_DIR and uClibc dynamic linker, use the one in the build dir. If people want the "both dir" behavior, I'll enable it similar to the "build" and "rpath" behaviors. See the comments in the file for how this works. Make selection of uClibc floating point support in printf, etc. seperate from libm float function support. Also, move all Config files out of the main directory. Add a _really_ basic README outlining building/using uClibc. Give Erik's build-with-uClibc method. Revert behavior of wrapper to not use dynamic linker in the build dir, so those who want to should now be able to compile against uClibc without installing it (using the "build" behavior). Look's like I need to disable the rpath stuff for now as well. To build with an uninstaled uClibc, set UCLIBC_GCC=build in your env, or rename it/symlink to it using a name containing the string "build". Removed INSTALL_DIR and replaced it with DEVEL_PREFIX, ROOT_DIR, and TARGET_PREFIX to allow more flexibility. Also modified the gcc wrapper to do the right thing if -Wl,--dynamic-linker,xxx is passed on the command line. The gcc wrapper will also check the env variable UCLIBC_GCC_LDOPT for a dynamic linker option at runtime (although command line arg overrides the env variable). Install ldd and ldconfig as appropriate. Added cmdline options --uclibc-use-build-dir and --uclibc-use-rpath so that those behaviors can be invoked from the command line. Fix bug: tried to install non-existant shared libs. Fix misuse of DO_SHARED and LDSO_PRESENT. Add -f option to "cp"s. Only build ldso if building shared. Also, if building ldso, build all subdirs. Always check before you commit...^100. We need to build the dynamic linker before we build shared libc. We need to build shared libc before libdl. Add locale-enabled strcoll function from vodz, plus supporting tool. Update the todo. Add my personal list. Commit _uClibc_fread bug fix (with minor edit) posted by Johan Adolfsson <johan.adolfsson(a)axis.com>. Fix bug in ldso/util/Makefile introduced when Erik added the readelf app. It didn't show up if a previous install was done. This would have been fixed two days ago if the initial bug report had been anything close to lucid. :-( Also changed ldconfig back to staticly linked and update the README file. Fix printf handling of %p to prepend "0x" since output is in hex. Note: glibc output for (void *)0 is "(nil)" while uClibc output is "0". Does anyone have a preference? Fix printf so that %p outputs "(nil)" for (void *) 0, to match glibc behavior. Add the in* and out* functions for i386. Note: the sys/io.h header for glibc-2.2.2 actually defines static inline versions for i386, but only provides prototypes for externs for the other archs I looked at. Since uClibc shares this header amongst archs, I stashed the inline defs in bits/io_i386.h and included it when __i386__ was defined. Better solutions are most welcome, but it doesn't clutter sys/io.h too badly and now lilo and the pcmcia tools build against uClibc on i386 without modification. Update TODO file. Remove Erik's broken implementation of rint(). Replace it by one "less broken". Also correct rounding beharior of round() and add trunc(). Note that round() and rint() currently don't check for infs and nans. I decided to wait on that until the big cleanup. Oops... forgot to remove rint.c from the makefile. Remove simulated d_type support for getdents and the dirent struct, and use the straight getdents syscall instead of the wrapper (which leaked memory). Note need to fix scandir.c's dynamic memory handling. ANSI/ISO specifies that no library function sets errno to 0. Yes... I forgot to update bits/dirent.h for the other archs. :-( For now, we need to explicitly make clean in libc/unistd (sysconf stuff) and libc/sysdeps/linux/common (unified syscall stuff). Make these PIC and _LIBC_REENTRANT compatible. Fix syntax error in comment. Remove obsolete files tell.c and getdents.c Remove nonstandard functions. Added a script to create bits/syscall.h for each arch. NOTE!!! This is run by "make -C libc/sysdeps/linux/$(TARGET_ARCH) headers" in the main Makefile, but I only changed libc/sysdeps/linux/i386/Makefile as I had no way of testing it for the other archs. Various arch maintainers, please check and update the corresponding Makefile... or report bugs ;-)... appropriately. You'll also want to "cvs del" syscall.h and add it to a .cvsignore in $(ARCH)/bits. Also added a define to uClibc_config.h, __UCLIBC_USE_UNIFIED_SYSCALL__, and moved i386 unified syscall stuff out of common and into i386/bits/syscalls.h. Optimized for size over speed to (substantially) reduce generated code size. Fix a missing include in des.c and add configurability of loop unrolling to md5.c. Note: by default it is smallest/slowest. These zero-length files apparently weren't deleted from cvs. Fix small typo vodz reported. Fix fread bug reported by Vodz. The fix is straightforward, but I haven't tested it (lack of time). Ok... the fix wasn't quite so straightforward. Hopefully this will do it. Yes... the previous "fix" was broken too... the result of careless cutting and pasting while pressed for time. I haven't checked this one either. :-( Back out the changes to _uClibc_fread and loop in fread() if incomplete, to avoid problems with fgets on tty streams. I actually did some testing this time. ;-) Note: there is a difference in behavior between glibc and uClibc here regarding fread() on a tty stream. glibc's fread() seems to return after reading all _available_ data even if not at end-of-file, while uClibc's fread() continues reading until all requested or eof or error. The latter behavior seems correct w.r.t. the standards. Oops... left in a debugging line. Fix fseek behavior. Output an error if uClibc's and app's largefile configuration are incompatible. I was confusing the effects of _LARGEFILE_SOURCE with those of _FILE_OFFSET_BITS regarding aliasing of the *64 funcs. :-( Hopefully, this version is correct... Swap in the new stdio code. Deal with cvs "feature"... or is that cvs _user_... Update to my current todo list. Oops.. had left thread support forced on. Fix fflush(NULL) and tweak _stdio_term() for the unbuffered stdio option. So much for fcntl flags being resonably consistent across archs... (hopefully) fix O_APPEND and O_LARGEFILE handling in _stdio_fopen(). Someone else will have to check of course... Fix another O_LARGEFILE bug. Also, I forget to make floating point optional in the new printf code. Apply Miles Bader's missing __va_copy() fix. Oops... forgot to update abort.c. Fix stdin/stdout initialization of buffering type. I had changed the default static initiailization and forgotten to update _stdio_init(). New versions of the various string to int functions which are smaller than the old ones, even with errno setting turned on now. Also, at least on i386, we no longer need the long long helper functions for division and mod from libgcc.a. Modified because of the new str to int funcs. I vow to rerun _all_ the tests before making commits. :-( I successfully managed to blow away all the modeflags for the file _except_ the one dealing with buffering... Fix a pointer bug in setvbuf reported by Bart Visscher <magick(a)Linux-Fan.com>. Forget to initialize thread locks for fake files. Thanks Erik. Fix an arg promotion handling bug in _do_one_spec for %c reported by Ilguiz Latypov <ilatypov(a)superbt.com>. Revert Erik's changes... they were broken since there weren't enough bits for the extra ISblank flag. Instead, hardwire isblank() to not depend on locale for now. At least it will work for space and tab in the immenent release. This will all be blown away for the next release anyway, as I should be committing my new stuff in the next day or two. Only set no buffering if we opened the file. Also, don't bother restoring buffering since we will close the file in that case anyway. Fix the read/write auto-transition bugs. Note that if we can't auto-transition, we fail the operation. This is different than glibc's apparent behavior for writing of clearing the read buffer and still failing the write without setting the stream's error flag. New locale support (in development). Supports LC_CTYPE, LC_NUMERIC, LC_TIME, LC_MONETARY, and LC_MESSAGES for the SUSv3 items. Also, nl_langinfo() when real locale support is enabled. New implementation of ctype.h. New implementation of wctype.h. New implementation of most of the string functions (smaller). New implementation of the wcs/wmem functions. These are untested, but they're also just preprocessor-modified versions ot the corresponding str/mem functions. Tweaked qsort and new bsearch. The obligatory forgotten files... Update my TODO entries. Forgot to change the Config templates. Changed one... the others are similar, but don't have time to take care of them. Protect against ctype macros. Adjust preprocessor logic to initialize QUAL_CHARS correctly for Erik's alpha port. Also, explicitly use the macro versions of isdigit and isspace in the printf and scanf code. Revert Erik's previous patch and fix what I believe he was trying to, while preserving the space-saving aliases. Multibyte and wide char conversion functions. Some work still to do, but they're quite solid now and Erik needs them for the gcc port. Comments at the head of wchar.c. Obligatory forgotten file during commit... Added a version of nl_langinfo for the stub C/POSIX locale support. Revert Erik's patch to vasprintf and fix the real issue. The writer for the stream returned by open_memstream was supposed to keep the buffer nul-terminated. I apparently left out a statement. I guess nobody's tried this stuff. I apparently checked in the wrong version several weeks ago. Commit the new time stuff, even though I haven't made it threadsafe yet. At least people can play with it. Also, fix a buglet in setenv.c. Fix perror() and printf("%m") to not call strerror(), as required by the standards. Temporarily added a utility function to wrap Erik's strerror_r so that "Unknown error xxx" strings can be generated for errno's which cause strerror_r to fail. That utility function will eventually be merged in with the strerror/strerror_r functions when I change over to optionallly mmap'ing the system error strings to provide for lower mem comsumption on non-MMU platforms, as well as locale-specific system error messages. Remove obsolete files. Add in thread locking for tzset() and associated data. Also, fix a bug so that localtime_r() calls tzset() to initialize/update timezone data. Update my todo list. Enable WCHAR support for C/POSIX stub locales. Implemented unformatted wide i/o functions. (ungetwc still needs testing) Fix a few bugs in wchar.c. Modifications for bcc/elks support. Update Config files for current locale and wide char configuration options. For now, have locale support automaticly enable wide char support. Things currently won't build otherwise. Update my todo list entries. Only define __uwchar_t if wide char support is enabled. Add two missing glibc wide string funcs as well as OpenBSD string funcs strlcat and strlcpy. Update header for strlcat and strlcpy. Add copyright message and remove dead code. Attempt to clean up the strerror_r situation. Obligatory forgotten file. Fix a preprocessor buglet. Redo sys_siglist/strsignal/psignal. Remove obsolete code. Clean up CLK_TCK situation. clock() and sysconf() now use an arch-specific constant value defined in bits/uClibc_clk_tck.h. Default is 100 (common/bits) but alpha uses 1024 following glibc. Override per arch as necessary. A couple of little cleanups I forgot to check in. Changed fflush() behavior to no-op for r/w streams in read-mode. This falls under undefined behavior wrt ANSI/ISO C99, but SUSv3 seems to treat it as a no-op and it occurs in some apps. Fixed a problem with _stdio_fwrite() not checking for underlying write() failures. Fixed both _stdio_fwrite() and _stdio_fread() to make sure that the putc and getc macros were disabled if the stream was in and error state. Enable getpt prototype. Add an entry regarding localtime(), TZ, and timezone support. Update my TODO list. In particular, breakdown what I'll be working on in the next two months. Revert commit by davidm to printf.c that initialized conv_num needlessly. To do so increases the generated code size with bcc. Eliminate duplicate define warnings in wstring.c. Fix potentially broken preprocessor comparisons. The preprocessor converts integers to maximal signed type, so inequality comparisons involving UINTMAX_MAX, ULLONG_MAX, and (if no long long) ULONG_MAX were potentially broken. __fsetlocking() and FILE field user_locking were completely broken. :-( I think they're fixed now (I've run a few tests). Note: __fsetlocking() is not threadsafe... but glibc's doesn't appear to be either. Fix erroneous grouping. Disable macro implementations. Somehow I missed the following from the ANSI/ISO C99 std... Fix two problems with printf that showed up in the python 2.2.1 tests; One involving %o and one involving %f. Fixed __read_etc_hosts_r to return alias list and modified buffer allocation accordingly. This fixes the segfault in the Python 2.2.1 socket test. Remove recursive lock/unlock for a non-recursive mutex. Fix broken locking so that at least the Python 2.2.1 grp test doesn't lock up. This really needs to be looked at, as I don't think this needs to be reentrant. In any case, several routines call the __getgrent internal routine and it uses static vars for data. If this stuff is really supposed to be threadsafe, then __getgrent probably needs fixing. Unlike glibc, uClibc doesn't always support the d_type field of struct dirent. So, disable the d_type support macros when d_type isn't available. This fixes a build problem file fileutils-4.1. Tweak things so that struct stat and struct stat64 (seem to) work on i386. This is for Erik to look at wrt the other archs. Changed fclose behavior when custom streams were enabled. Previously, the cookie pointer was set to NULL as a debugging aid. However, some of the perl 5.8 test rely on being able to close stderr and still try writing to it. So now, the cookie pointer and handler function pointers are set to that it is a "normal" file with a file descriptor of -1. sparc, alpha, and mips have different errno values than the other supported platforms. Adjust _susv3_strerror_r function to deal with this. Also fix an error in strerror() wrt invalid errnos. Make this as glibc-like as possible while avoiding the fileutils problem. glibc hides the DT_* enum values unless __USE_BSD is defined. Reimplement sys_errlist[] so that it works on sparc, alpha, and mips. In my opinion, this is a complete waste of good memory and is only done to avoid the anticipated whining by people who think this libary is named uCglibc. At some point this may become a configurable option. And even then, it may not be available in all configs... for instance when system error messages become locale-dependent. Obligatory forgotten file... sys_errlist garbage. Add #include <malloc.h> to silence warning. Patch from Tero_Lyytik�inen <tero(a)paravant.fi> to fix bug in matchchar case. Clean up a warning. Remove malloc_simple from subdir list. Hide my personal #warning reminders. Add __wcschrnul, rename strchrnul to __strchrnul, and add weak aliases for them. Add SUSv3 function getsubopt. Add gnu obstack support. I still need to implement the obstack_printf and obstack_vprintf, but at least now the reiserfsprogs build. Allow timezone info to be specified in a file... /etc/TZ. Turned on by default for now. From the comments... ANSI/ISO C99 requires assert() to write to stderr. This means that writing to STDERR_FILENO is insufficient, as the user could freopen stderr. It is also insufficient to output to fileno(stderr) since this would fail in the custom stream case. I didn't remove the old code though, as it doesn't use stdio stream functionality and is useful in debugging the stdio code. Fix a problem in vasprintf (reported by vodz a while back) when built without custom stream support. In that case, it is necessary to do a va_copy. Note: The affected code is not built in the stock config. Also, make sure each va_copy has a matching va_end, as required by C99. Fix a couple of 'restrict' bugs in mbstowcs and wcstombs. Work around glibc brain-damage regarding nl_langinfo and {mon_}grouping entries. Add a few more entries. Reworked setlocale() return values and locale arg processing to be more like glibc. Applications expecting to be able to query locale settings should now work... at the cost of almost doubling the size of the setlocale object code. Fixed a bug in the internal fixed-size-string locale specifier code. Fix a stupid bug. Implement locale-specific grouping in printf for base 10 integer conversions when the grouping flag "'" is specified. Grouping for floating point values may wait until I do a rewrite of the floating pt to string code... It was easy enough to respect locale-specific decimal point for printf floating point output, so at least implement that. But grouping will have to wait for the rewrite of _dtostr. This fixes a broken build for me. Add printf wchar support for %lc (%C) and %ls (%S). Require printf format strings to be valid multibyte strings beginning and ending in their initial shift state, as per the stds. Hit the highlights of glibc differences in my code. Not yet complete though. Forgot to change btowc and wctob when I changed the wc<->mb functions yesterday. Apparently I forgot to build atof... Okay, fix for atof _correctly_... Remove atof from strtod.o... Add wcwidth and wcswidth, based on Markus Kuhn's wcwidth of 2002-05-08. Added some size/speed optimizations and integrated it into my locale framework. Minimally tested at the moment, but the stub C-locale version (which most people would probably be using) should be fine. Added some temporary "stubs" for collation. strcoll is an alias for strcmp. strxfrm is an alias for strlcpy. wcscoll is an alias for wcscmp. wcsxfrm is implemented as a wchar version of strlcpy. Real locale-dependent implementations are coming soon. Add notes about setvbuf and struct tm extension fields tm_gmtoff and tm_zone. Ok... here's the summary: Hopefully locale support will build when cross compiling now. Collation is still not supported, but that's what I'm currently working on. In the next couple of days, I'll probably put up a couple of files for download that will save people the trouble of generating all the glibc locales. Added *wprintf functions, although they currently don't support floating point. That will be fixed when I rewrite _dtostr... or possibly before. Added the wcsto{inttype} functions. Added iconv() and a mini iconv utility. The require locale support and only provide for conversions involving the various unicode encodings { UCS-4*, UCS-2*, UTF-32*, UTF-16*, UTF-8 }, the 8-bit codesets built with the locale data, and the internal WCHAR_T. Oops.. left in a bit of debugging code. Fix bug in setting daylight and timezone when no (valid) TZ. Bug reported by Arne Bernin <arne(a)alamut.de> in regards to freeswan. Fix an ifdef mismatch. Add hsearch and hsearch_r. Consolidate all functions prototyped in search.h in one directory. Forgot one... Cut and paste error. Remove trailing comma from enum list as a nicety for older compilers. The big thing is locale dependent collation support. Also added outdigit support and (legacy) YESSTR/NOSTR support. Add a target so that people can download and use pregenerated locale data files instead of generating approx 40Mb of glibc locales to get the 300+ locales currently supported. Obligatory forgotten update... Update. Fix a silly bug in _wstdio_fwrite. wprintf %s should now work correctly. For now, "#if 0" out the inlining of (currently unsupported) glibc-specific string->numeric conversion functions. Fixed a bug related file position in append mode. _stdio_fwrite now seeks to the end of the stream when append mode is set and we are transitioning to write mode, so that subsequent ftell() return values are correct. Also fix _stdio_fopen to support fdopen() with append specified when the underlying file didn't have O_APPEND set. It now sets the O_APPEND flag as recommended by SUSv3 and is done by glibc. Wasn't thinking... we don't need to seek to end when appending if stdio is built without buffer support. Remove bogus link_warning. It is meaningless and stupid. While the previous committed patch was well-meaning, the #warning it replaced was simply a reminder I accidently left in when implementing strcoll/wcscoll. Besides, strcmp is completely locale invariant. Fix (hopefully) scanf behavior for nul bytes in the stream when processing %c, %s, and %[ specifiers. Note that scanf is undergoing rewrite so I didn't bother optimizing this. I did run all my regression tests though. Set EOF correctly for fmemopen on readonly streams. I really need to check what glibc behavior is for the various open modes though. Sorry. Changed this while fixing the last bug and forgot to change it back. Unfortunately, none of my test cases caught it. Add memmem(). Ok... pasting in DUMPn() is unnecessary and technically incorrect. Optionally support the struct tm extension fields. Add a few misc functions mentioned in time.h. Revert davidm's change regarding using a define for the "/etc/TZ" path, as this is eventually meant to be a configurable extension and not unconditionally supported. Change 'undefined behavior' of fflush() on readonly or reading streams to match that of current glibc; i.e. don't do anything and return success. Apparently, php calls fflush() on a file opened as readonly before trying to read. Eventually I'll add some config options to flag this and several other instances of nonportable code. Yikes! This was doing another lock instead of unlocking the stream. Bug fix from Peter Kjellerstedt <peter.kjellerstedt(a)axis.com>. vfscanf was not setting the FILE bufread member to flag the end of the buffer. Also, do not set bufgetc member if getc macro support is disabled. Add a new *scanf implementation, includeing the *wscanf functions. Should be standards compliant and with several optional features, including support for hexadecimal float notation, locale awareness, glibc-like locale-specific digit grouping with the `'' flag, and positional arg support. I tested it pretty well (finding several bugs in glibc's scanf in the process), but it is brand new so be aware. Fix a silly error. Replace 'new' in a prototype to avoid c++ problems. Fix a cut-and-paste error. Collation should be working again. _wchar_utf8sntowcs and _wchar_wcsntoutf8s now set errno if EILSEQ. scanf %lc,%ls,%l[ would always set mb_fail on eof or error, even when just starting a new mb char. wscanf would incorrectly unget in certain situations. Fixed a bug where locales nontrivially derived from iso14651_t1 did not have the UNDEFINED entry set properly. Work around a bug in nm from binutils-2.14.90.0.5. Correct included header for ustat. Fix a few bugs in the new extended locale functions. Move stub gettext functions to a stub libintl to make switching in gnu gettext easier. Also add a few gnu-isms. Change to using hidden names with global weak aliases for the extended locale functions, as expected by libstd++. Slightly rework the locale data generation stuff to allow pregenerated locale data to be used with buildroot. Add missing header. Create a typedef for the ctype bitmask table entries. Hack a fix for ctype support of 8-bit codeset locales. Some doc updates. Fix precision bug for %g conversion specifier when using %f style. Rework a few things. Hack around bg_BG bug; grouping specified but no thousands separator. Also, disable the locale link_warnings for now, as they generate a lot of noise when using libstd++. Only define __STDC_ISO_10646__ if wide char support is enabled. Some more buildroot-motivated fixes. Avoid installing some headers, as well as stub libintl, depending on configuration. Oops... Forgot to convert this to the new floating point conversion func. Move an #endif that was in the wrong place. Always build _store_inttype since it is used by the new scanf. Don't install floating point related headers, and wrap some previously unwrapped prototypes, when float support is disabled. Also don't install printf.h if glibc custom printf specifier support is disabled. Small fix for when threading (I think) was disabled. Update old_vfconfig help and some dependencies. Implement vsnprintf (old_vfprintf only) and vsnscanf when uClibc is configured with non-buffered stdio and non-wchar mode. Fix a couple of bugs that showed up in minimalist configurations. Update old_vfprintf to handle size qualifiers on the integer and %n conversions. It now passed the glibc printf tests with the exception of a floating point rounding difference. Remove profil.c, since it is constained within gmon.c. i386/mcount.S expects to call __mcount_internal with the 2 args passed in registers. Add back in table-less ctype funcs for those interested in minimizing static build sizes and not needing wchar support. Add in a SUSv3 getopt as an option for those not needing gnu getopt. Again, mainly for the static linking crowd. Obligatory forgotten file. Signifcantly speed out integer to string conversion for printf. Printf still needs some performance work done though. Also some bufferless stdio cleanups. Fix wctype.c so that wchar can be enabled without ctype table-based functions. Patch by Atsushi Nemoto <anemo(a)mba.ocn.ne.jp> to do arch-required mapping of signal strings (alpha, mips, hppa, sparc). Fix a problem reported by Atsushi Nemoto <anemo(a)mba.ocn.ne.jp> for environments where long and long long are the same size. This should enabled building of uClibc locale support when using uClibc itself. Sorry I didn't test this before the release. Fix "subst -g,," problem for SAFECFLAGS. Ugh... EOF handling by scanf was completely broken. :-( Regretably, I got my mind fixed in one mode and didn't comply with the standards. Things should be fixed now, but comparision testing is difficult when glibc's scanf is broken and they stubbornly refuse to even acknowledge that it is... even when confronted by specific examples from the C99 standards and from an official C standard defect report. Modify _stdio_READ to conform with C99, as stdio input behavior upon encountering EOF changed with Defect Report #141. In the current standard, the stream's EOF indicator is "sticky". Once it is set, all further input from the stream should fail until the application explicitly clears the EOF indicator (clearerr(), file positioning), even if more data becomes available. Fixed a bug in fgets. Wasn't checking for read errors. Minor thread locking optimizations to avoid some unnecessary locking. Remove the explicit calls to __builtin_* funcs, as we really need to implement a more general solution. Document some glibc bugs that Ulrich Drepper refuses to acknowledge. :-( One more scanf difference. Quick fix to make sure vfprintf always checks stream orientation when wchar support is enabled. Add -msoft-float to SAFECFLAGS when necessary. Some more soft float fixes... for arm in particular (libfloat). Remove the ADD_LIBGCC_FUNCTIONS option and do things the right way. Either we have a shared libgcc available, or the libgcc routines aren't PIC and don't belong in the shared libc anyway. Fix Erik's typo. Hopefully fix the struct tm extension problem once and for all. Also fix a dst-related bug which caused the use of uninitialized data. If realloc failed, we'd lose the pointer to the exit function table. Remove erroneous trailing semicolon. Rewrite the pwd.h, grp.h, and shadow.h functions (except lckpwdf/ulckpwdf). Oops... don't need recursive mutexes. Add a utility macro. Sigh... I wasn't checking if the gid field in a group line actually contained a digit. Also adjust a comment. Add clock_gettime() submitted by Justus Pendleton <uc(a)ryoohki.net>. Protect some header inclusions. Fix for the last "fix". Fix a build problem when using 2.2.x kernel headers. Don't install shadow.h if shadow password support is disabled. Patch from Jeffrey Baitis <baitisj(a)evolution.com> for mips arch tuning. I forgot to update the thread locking in the last dst fix. If __NR_ftruncate64 isn't defined, do the best we can. Kill ARCH_HAS_NO_MMU and use HAS_FPU only. Wether floating point ops are implemented in hardware or via kernel emulation doesn't matter to the libc code. Fix the return value for fputs when passed an empty string. Indirectly detected by gmp-4.1.2 self-tests and reported by "Peter S. Mazinger" <ps.m(a)gmx.net>. Always include locale.h, which was included by libintl.h only when optimizing. Make sure the utils build gets the setting for CROSS. Fix arm detection for libfloat. Protect against quoting changes. Hopefully this is correct for cris. Make sure we use the right CC setting when building utils. Not doing so was breaking the buildroot softfloat arm build. Ok.. this fixes the buildroot soft-float arm build. Also try to make sure the build breaks if we want soft float but don't know how to request it. Don't bother checking, since we want an error if -msoft-float doesn't work. Add -msoft-float to CPU_CFLAGS instead of CFLAGS, since ldso and libdl Makefiles ignore CFLAGS. Add sysmips(), based on a patch by Atsushi Nemoto <anemo(a)mba.ocn.ne.jp>. Another missing mips function, needed by the boehm garbage collector. Patch by "Bradley D. LaRonde" <brad(a)ltc.com> for boehm garbage collector. Minor update... Config no longer used. Minor typo fix. Put in a dummy reference to main so busybox will link. Add a syscall() implementation using a hacked version of the syscall6 macro. Untested, but syscall() is needed by busybox for pivot_root at least. Include Rules.mk for consistency. Trying not to was simply too painful. Building of iconv.o was accidently always disabled. Also, build the iconv app in utils. Don't download the local data if we have it already. Fix infinite loop in putgrent (forgotten increment). Fix a couple of 'declaration after statement' errors. Fix some dst issues in _time_mktime(). Normalize the tm_isdst value to -1, 0, or 1. If no dst for this timezone, then reset tm_isdst to 0. Link ldconfig with the appropriate libraries. Fix a long-standing bug with pthreads. A couple of linuxthreads files were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. Handle the app_fini stuff in exit without requiring atexit(). This avoids pulling in all the malloc/free code for a simple true/false app. Kept the same approach, but rewrote the code for the most part. Fixed some minor issues plus (as I recall) one SUSv3 errno case. Minor fix from upstream glibc. Rewrite popen for SUSv3 compliance. Added a list of popen()'d to store pids and use waitpid() in pclose(). Loop on waitpid() failure due to EINTR as required. Close parent's popen()'d FILEs in the {v}fork()'d child. Fix failure exit code for failed execve(). Redo the exec functions to comply with SUSv3. The checking Erik added seems to be unnecessary. Without it, I am not seeing any LTP failures. Oops... temporarily support the old stdio code. Fix __freadable and __fwritable... were using '~' instead of '!'. (ugh) Fix (hopefully) a potential problem with failed freopen() calls. The fix isn't tested since I've been working on the replacement stdio core code which will go in after the next release. My mistake. We do need some weak pthread_* funcs. But we were previously missing one in the glibc abi, and including a number of extras (which I left in commented). Unfortunately, this brings back the perl pthread bug. Fixing the incorrect weaks in libpthread wasn't sufficient to escape the shared loader bug. :-( Oops... Seems I forgot an else... Add another devfs subdir to the list of checked subdirs. Add a dummy (always fails) wcsftime. This is needed for the libstdc++ locale implementation to build. Later this month I'll add a functional wcsftime. Ok.. we need to link with libgcc.a for some archs. I haven't looked at all cases, but the archs I've looked at do build the needed routines as PIC so we should be ok. Link with libfloat if necessary. We need to link with libgcc.a when creating shared libs, in order to avoid problems 'hidden symbol' problems. Also handle -lfloat for the soft-float arm case. Prevent runaway asserts, which can happen if there's a problem with stdio or locales. Add __data_start needed by boehm garbage collector, in turn needed by libgcj. Use the correct configuration test define. Today's Toni's birthday. Seems an appropriate day to add this. Allow building on 64 bit archs. Hopefully the last cvs activity this stuff will see other than "delete". Patch from Alan Hourihane <alanh(a)fairlite.demon.co.uk> for building alpha. Fix bug from the syscall reorganization, detected by python's test_poll.py. The #ifdef __NR_poll test was failing because it was done before any includes. Hence, the emulation was always being used. New stdio core. Should be more maintainable. Fixes a couple of bugs. Codepaths streamlined. Improved performance for nonthreaded apps when linked with a thread-enabled libc. Minor iconv bug and some locale/thread related startup issues fixed. These showed up in getting a gcj-compiled java helloworld app running. Removed some old extension functions... _stdio_fdout and _stdio_fsfopen. Oops.. The custom stream funcs should only be compiled if wanted. Fix this as should have been done a long time ago... Generic fork works. Use it instead since this didn't handle errno_location. Sigh... Fall back to alloca() if munmap is broken (uClinux). Patch by Joakim Tjernlund <joakim.tjernlund(a)lumentis.se>, which got mips mostly working. From there, I tracked the bash failure to a bad _dl_atexit address and Erik took it from there. Bug fix: gethostbyname2_r would fail if /etc/host was missing. Bug fix: gethostbyname_r checked errno without first setting it to a known value. Rewrite the err/warn functions as they were broken (__noreturn__ funcs were returning). Anyway, also make them threadsafe and smaller. The error.c file still needs work. Fix typo. Add missing include. Fix a couple of issues in configurations I hadn't tested. "Fix" this so that at least things will link when threading is disabled. Also fix the sizeof() issue since the change to a dynamicly allocated buf. Note! This is still broken wrt threading, but so is the glibc version. I'm just commiting this for new until I can test my rewrite. Patch from Yoshinori Sato <ysato(a)users.sourceforge.jp>. Peter Mazinger asked for this several months ago. Change clock() to allow wrapping. Add timegm() function. Make lookup_tzname() static (as it should have been). Have strftime() get timezone information from the passed struct for the %z and %Z conversions when using struct tm extensions. Obligatory forgotten file... Fix changed link into the mailing list archive. Hide the arm libfloat support for now. No longer needed for gcc 3.4.1 and won't be needed for 3.3.4 either when I get some time to clean up that toolchain which also suffers from the g++ include dir search order bug. Follow glibc's lead and add a gcc-3.4.1 required symbol to crt0.S. Some mips updates. Add a couple of missing sys/*.h files and update a few others. At solar's request...

Apparently the sigaction code added was broken, as it generated illegal instruction errors. Disable it for now. Fix mips bug related to 2.6 headers by following glibc's lead. Based on the comment, newer kernels appended "64" to __NR_pread and __NR_pwrite. Always include the sqrtf wrapper in libm so that we don't need to worry about conditionally configuring something else for libstdc++. Logic was reversed. Update to add missing c++ namespace support. Fix dependencies. Patch by Carl SHAW <carl.shaw(a)st.com>... Fixes from gentoo. solar asked that this bit be reverted. Fix a couple of symbol name issues. Add a couple of mips-specific string funcs. Port the generic optimized string funcs from glibc, with some tweaks to cut their size a little. The main change is making memmove call memcpy for forward copying to trim redundant code. Make use of both the generic and arch-specific speed-optimized string funcs configurable. Arch-specific take precedence over generic, and generic takes precedence over basic size-optimized uClibc funcs. Hide some x86-specific devel asserts. Rip out Peter's unacceptable "fix" and do the sane thing instead; build the utils using the uClibc-targeted toolchain. Jocke's patch was almost right. Just needed move the DT_MIPS_RLD_MAP test up a bit. Native and remote debugging of shared libs and threaded apps now works on mips. Revert Peter's __lib_gettimeofday patch. There's the minor issue of adding cruft to include/sys/time.h. But also, there's no sense in making changes like this until we decide how we're going to approach the hidden symbol transition. Fix some issues with nice(). SUSv3 specifies that it return the new priority if successful, while the linux syscall returns 0. Also, in the non-syscall version, we must be sure to set errno to EPERM on failure since setpriority() can set errno to several possible values. Note: The version of glibc on my debian system is broken wrt EPERM too. When I broke up the stdio code, the "support pre C99 compilers" va_copy compat define was no longer visible to vasprintf. I didn't catch this since I no longer use such old tools. Unfortunately, some well-meaning but misguided individual decided to just cut-and-paste the macro. :-( Try to clean up the situation by putting it into a header that can be overriden by any archs that need to. If this breaks for anyone (as I said, I no longer use such old tools and so haven't tested), let me know and I'll fix it. Unlike the other static libs, libdl.a and libdl_pic.a are different. So we need to copy the actual libdl_pic.a or bad things happen when optimizing libdl.so with mklibs.py. Fix reported bug in error return behavior of sem_timedwait(). Revert last commit. If I had wanted to include that patch, I would have done it myself at least a year and a half ago. Forgot to change name of builtin buffer during last rewrite. Replace IXDR_GET_LONG/IXDR_PUT_LONG so that they build with newer gcc. Note the comment in the code. Change strptime so that it only modifies struct tm fields specified. Since __syscall_error is a C func, we need to store the syscall return value in the appropriate register. Otherwise, errno is set to random garbage. Fix 2 bugs in strftime related to glibc struct tm extensions. 1) Need to negate tm_gmtoff field value when used. (bug 336). 2) Deal with NULL ptr case for tm_zone field, which was causing segfaults in both the NIST/PCTS tests and the Python 2.4.1 self-test suite. NOTE: We set uninitialized timezone names to "???", and this differs (intentionally) from glibc's behavior. A while back, the sysvipc code was changed to use IPC_64 in the calls. Unfortunatly, the semid_ds structs were not changed as needed. So import the necessary (tweaked) files from glibc. Only tested on x86 today, but I'll be testing mips tomorrow. Add a config option for abort() to shutdown the stdio subsystem. This is mainly to cut down on noise in the NIST/PCTS tests since older POSIX behavior was to fclose() (and hence fflush()) all open streams. Fix string.h. Change our _susv3_strerror_r to __xpg_strerror_r for glibc compatibility. Also change _glibc_strerror_r to __glibc_strerror_r for consistency. sjhill appears confused. vapier's earlier commit of string.h was broken. But I fixed it, and tested both x86 (locale) and mipsel before I commited the fixes. Just built with gcc 4.0.1 to see if that was the cause of his problems, but x86 (locale) built fine. So revert his last change. Since we're now always using IPC_64, we need this. Otherwise, some of the perl tests fail on mipsel. Update with current glibc version. Sigh... I wasn't checking for output errors. NIST/PCTS caught it. Hack in some temporary fixes until I have time to clean it up a bit more. Also rework _fpmaxtostr to reduce the size a bit and (hopefully) allow it to build for m68k (vapier tested an earlier version a while back). Check for __NR_fcntl64. This fixes the pread/pwrite bugs reported by ltp. But I really need to pull in the latest glibc stuff. Old glibc fix for ltp's clone07 test. Another file that needs updating... POSIX requires that fields st_dev and st_rdev to be of type dev_t. Update from (older) glibc code.

The are a few deadlock conditions where functions may be called which lock the utmplock but never release it and where a function that hold the lock calls other functions which try to relock the same lock. For example, notice in the __getutent function the error condition does not unlock the semaphore. The problem is not visible when pthreads isn't used since the lock/unlock functions are NOOP functions.

Richard Sandiford writes: This patch fixes a miscompilation of mmap() for Coldfire with gcc 4.x. The problem was that the syscall was being invoked before any part of the argument structure (buffer[]) had been initialised.

It is supported for 68020 and above, but not for 68000, 68010, or Coldfire, where using -fPIC leads to a compiler error. (Note that the error is flagged by cc1 proper, so it probably wouldn't have mattered with older compilers. It only matters now because cc1 is used to preprocess assembly code.)

Problem is in newopt, at gen_wctype.c:865: memcpy(tbl->ti + i * blocksize, ti[uniqblock[i]], blocksize); if we cannot generate a locale, be a bit more specific in telling the user we are skipping it Michael Troß writes: Yes, the missing initialization of uniqblock seems to cause all this trouble. Now gen_wctype works without the rlimit stack hack. also kill gdb files when building BFLT files use local labels if function or stack are NULL, make sure errno is set to EINVAL blackfin needs NOPs after the loop end when the last statement in the loop is an if/jump revert previous nops in strcmp as they are not needed here Bernd Schmidt writes: too many semicolons!

There is code in fclose() to remove a file handle from _stdio_openlist however it's commented out, allegedly because it is dead. _stdio_openlist is used in several places, including _stdio_term when a program exits. fclose() frees the struct, so I don't see how the code can possibly be redundant. we crash if the first argument to realpath() is non-null as well so lets mark both arguments as being non-NULL revert previous change; reading POSIX spec some more says we need to set errno to EINVAL if filename is NULL handle file_name==NULL and file_name=="" as required by POSIX import a slightly modified realpath() test case from glibc use __FDPIC__ from the compiler rather than setting our own enable -std=gnu99 by default now Atsushi Nemoto writes: Add st_[amc]timensec to N32/N64 version of stat, add st_[amc]time_nsec to each kernel_stat, and define STAT_HAVE_NSEC to convert them run through Lindent Kay McCormick reports: when evp is NULL, it is reset too late and so can cause a crash when it is dereferenced we dont actually need asm/page.h Atsushi Nemoto writes: This patch imports INLINE_SYSCALL, etc. from glibc-2.5 ports and implements _syscall[0-7] by using them, like arm and powerpc. Atsushi Nemoto writes: Current ucontext_t does not match with kernel's definition. Also, on N32 ABI, we can not use kernel's struct sigcontext since kernel's sizeof(long) and user's sizeof(long) is differ. use /*...*/ comments rather than #... so we can preprocess cleanup style add silentoldconfig target make sure we declare TARGET_ARCH as a string pull latest kconfig from kernel make arch default to hostarch Atsushi Nemoto writes: When I imported INLINE_SYSCALL, etc. from glibc, I just copied whole macros for each ABI.

When the offset is negative it is not correctly handled due to a missing shift operation, so it is passed to the syscall as the highest unsigned positive value. Daniel Jacobowitz: sleep()/usleep() relies on nanosleep() being a cancellation point but the files have "libc_hidden_proto(nanosleep)" which means it always calls the libc.so version, never the wrapped version in libpthread.so that's a cancellation point. Nickolai Zeldovich writes: Currently, tcgetpgrp() in uClibc uses an int to store a PID (fetched via ioctl TIOCGPGRP). This causes problems on platforms where pid_t is defined to be larger (e.g., uint64_t). Other functions in termios, such as tcgetsid() and tcsetpgrp(), already pass a pid_t to ioctl(), so the following patch does the same in tcgetpgrp() as well. exercise all required POSIX pthread cancellation points cancellation-points needs librt give proper prototypes Nickolai Zeldovich writes: if the temp name already exists, then the retry code does not create a new temp name as the code to do so is outside of the retry loop use POSIX -eq rather than bash == #1360 Jean-Christian de Rivaz writes: I actually suspect this code into the file uClibc/libc/sysdeps/linux/common/poll.c: tval.tv_nsec = (timeout % 1000) *1000; <==== make only usec! From milisecond this really needs a * 1000000 to make nanosecond. Without this a 1100 milisecond timeout is converted into a 1 seconde and 100 microsecond timeout! This can explain the weird result of the test code. Atsushi Nemoto writes: http://www.opengroup.org/onlinepubs/009695399/functions/posix_fadvise.html states it returns error code instead of setting errno.

And I don't think that there are people who are still using the 'stupid' GCC which cannot handle -iwithprefix, at least it works with gcc-3.3.x. Make sure that the DSO has an hash table into its elf, otherwise skip the lookup over next DSO. cleanup code style do not check the pointer before freeing it since free(NULL) works just fine This patch will fix a problem when the same host is defined with both IPv4 and IPv6 entries in /etc/hosts. Previous only the first of these host would work, as uClibc would read the /etc/hosts file from top to bottom, failing if the first hit did not match the IP type. Do string comparisos as late as possible during symbol lookup. import trunc()/truncf() for ISO C requirements, otherwise fortran can hit infinite loops when it generates builtins+trunc() substitutes add hidden defs for execv/execlp for completeness mark a bunch of public mem/str functions as weak so that people who insist on their own local copies while static linking dont hit link failures when other uClibc code force the libc.a objects to be pulled in via the hidden alias symbols plug a memory leak when using execl* functions on no-mmu michael_d in #1849 writes: The getcwd() implementation in the absence of a getcwd syscall has an off-by-one allocation bug.

They are based on a recent SVN checkout (12/05/2007). if an arch does not provide __NR_mmap, fall back to __NR_mmap2 (this just generalizes what Blackfin was already doing) update my e-mail address sync with glibc to get the extern inline directive add info for elf.h, ldd.c, readelf.c, and MAINTAINERS this code does not actually rely on INTERNAL_SYSCALL use the __extern_always_inline define from cdefs.h instead of duplicating gcc version checking in every pt-machine.h header ... while __extern_always_inline should work fine, i think what is intended is __extern_inline ... should double check later fix memory corruption on no-mmu from doing multiple execls where earlier execls fail by simply not releasing the memory reserved for the arguments of children processes test to make sure the buffers used by the gethost*_r functions handle misaligned scratch buffers the _dl_errno extern already exists in common headers, so no need for a local one change NO_UNDERSCORES to just UNDERSCORES so as to be less confusing when doing double negatives Daniel Jacobowitz writes: MontaVista noticed that when their kernels were configured to trap on unaligned access gethostbyname_r could mysteriously crash. I tracked this down to an unaligned buffer being passed to gethostbyname_r from some other part of uClibc (afraid I don't remember where from any more). We have to pad the beginning of the buffer to a pointer alignment before we store pointers in it. no need to delete the binary upon failure add workaround for gcc-3.4.6 with mips fix broken whitespace in many places; no functional changes fetch queue.h from latest freebsd cvs cull useless headers and import a few updates from glibc give execlp() its own cache on no-mmu to avoid recursive cache fighting fix typo pointed out by skinkie in #2194 posix_fadvise64 on 64bit systems take 5 arguments, not 6, as pointed out by skinkie in #2194 Ricard Wanderlof writes: The following definitions in getaddrinfo.c seem redundant as they _are_ defined in the public netdb.h header, contrary to the comment.

Extend __gen_tempname with mode argument Unbreak sem_open when UCLIBC_SUSV3_LEGACY is not defined Miles Bader (112): Remove extraneous file Re-add files which were mistakenly deleted during the big bits/ update. Initial checkin Add EM_CYGNUS_V850. Generic implemention works for v850 now, so we don't need a special version. Remove v850-specific versions of truncate64.c and ftruncate64.c. (L_dummy_main_reference): Reference the C symbol `main', not the linker symbol `main'. Just tail-call __uClibc_main. There's no real point to calling abort if exit failed, and abort drags in some unecessary grot. Don't bother zeroing BSS, since actually we _can_ rely on the loader to do it. Use __off64_t instead of off64_t. Grumble... Rename mutex stuff to use heap-specific names. Doc fix. Doc fix. * Automatically try to unmap heap free-areas when they get very big. (__ASMNAME): Use C_SYMBOL_PREFIX. (__ASMNAME2): Macro removed. Remove, since it's entirely incorrect Misc small cleanups. Factor out some common code sequences into inline functions. Redo the locking, so that it may actually work. Now locking is done at the malloc/free level, not within the heap abstraction, and there's a separate lock to control sbrk access. Miscellaneous tidying-up. Size tweaks. Add macros to abstract the malloc header format a bit. Use new malloc header macros. Implement shrinking. Fix bug when growing an allocation. Use new malloc header macros. Define MALLOC_SET_SIZE to take the user-address rather than the base-address. MALLOC_SET_SIZE now takes the user-address rather than the base-address. Update the size of grown/shrunk allocations. MALLOC_SET_SIZE now takes the user-address rather than the base-address. Make sure NEW_SIZE is a multiple of HEAP_GRANULARITY. Calculate amount freed when shrinking correctly. (MALLOC_HEADER_SIZE): New macro. (MALLOC_BASE, MALLOC_ADDR): Use it. Use MALLOC_HEADER_SIZE. Account for MALLOC_HEADER_SIZE when calculating new size. Update debugging printfs. In the allocate-and-copy case, don't include the malloc header in our size calculations. (HEAP_MIN_SIZE): New macro. (HEAP_MIN_FREE_AREA_SIZE): Increase size. Enable debugging if HEAP_DEBUGGING is defined. (MALLOC_REALLOC_MIN_FREE_SIZE): New macro. Enable debugging if MALLOC_DEBUGGING is defined. Use MALLOC_REALLOC_MIN_FREE_SIZE. Use `return' for null pointers, to avoid a giant block holding the rest of the function. Initial checkin. (CSRC): Add syscall.c Handle zero NEW_SIZE case. (__malloc_likely, __malloc_unlikely): New macros. Add flow-control hints with __malloc_likely and __malloc_unlikely. Use __malloc_unlikely instead of `likely'. (headers): Remove special case for v850, now that the general case works correctly for non-MMU systems without a `nommu' suffix. Fixup indentation a bit. (errno): Only define as a macro if __UCLIBC_HAS_THREADS__ is defined. (__set_errno): Just assign to `errno' (which will be expanded to the thread-friendly version when appropriate). (h_errno): Only define as a macro if __UCLIBC_HAS_THREADS__ is defined. (__set_h_errno): Just assign to `h_errno' (which will be expanded to the thread-friendly version when appropriate). (_res): Define as a macro if __UCLIBC_HAS_THREADS__ is defined, regardless of _LIBC. Remove thread-specific stuff entirely. Make INCLUDE_FULL_RPC default to !HAVE_SHARED. Remove __res_state function. whitespace (MALLOC_SETUP): New macro. (MALLOC_SET_SIZE): Take the base-address of the block, not the user-address. (MALLOC_ADDR): Macro removed. (malloc): Use MALLOC_SETUP. (realloc): Follow new arg conventions of MALLOC_SET_SIZE. Initial checkin. (CSRC): Add `memalign.c'. (CSRC): Make contents source files, not object files. (initfini.s): Search the uClibc include dir, so we can find <features.h>. Initial checkin. (likely, unlikely): New macros. (__malloc_likely, __malloc_unlikely): Macros removed. (likely, unlikely): New macros. Use `likely' & `unlikely' instead of the `__malloc_'-prefixed versions. (__heap_free): Tighten up the inner loop, and make the code more readable. Doc fix. Add __kernel_ino64_t. Make __kernel_loff_t unconditional. Redo stat structures (kernel changed too). (__heap_delete): Renamed from `__heap_unlink_free_area'. (__heap_free_area_alloc): Use __heap_delete. (__heap_is_empty): New macro. (free): Update debug statement. Update to use __heap_delete and __heap_is_empty. Change <bits/syscall.h> to <bits/sysnum.h>. Update debugging hooks. Initial checkin. (realloc): Record the correct size in the malloc header in the case where we extended the existing allocation, and got back more than we asked for from the heap. (__heap_check_failure): New function. (__heap_check): Add more checks. Use `__heap_check_failure'. * Add support for uClinux's broken munmap, contingent on __UCLIBC_UCLINUX_BROKEN_MUNMAP__ (which is currently not defined anywhere). This makes other cases a tiny bit less efficient too. * Move the malloc lock into the heap structure (locking is still done at the malloc level though, not by the heap functions). * Initialize the malloc heap to contain a tiny initial static free-area so that programs that only do a very little allocation won't ever call mmap. Fix locking to not deadlock when __UCLIBC_UCLINUX_BROKEN_MUNMAP__ is defined. Get rid of old malloc lock stuff. Use __heap_[un]lock instead of __malloc_[un]lock. (uClibc_config): Define __UCLIBC_UCLINUX_BROKEN_MUNMAP__ for MMU-less systems. Don't infinitely recurse when trying to grow __malloc_mmb_heap. Make `-nostdlib' and `-nodefaultlibs' work correctly. Add appropriate -I options so that any files included by unistd.h are found correctly. Tweak the whitespace of the generated file. Define TOPDIR to be just `.' when invoking gen_bits_syscall_h.sh, since we've already chdir'ed to $(TOPDIR). * Make -DNDEBUG depend on DOASSERTS, not DODEBUG * Make -msoft-float depend on USE_GCC_SOFT_FLOAT_OPTION, not UCLIBC_HAS_SOFT_FLOAT. (DOPIC): Depend on !HAVE_NO_PIC. (UCLIBC_HAS_FULL_RPC): default to `y' if !HAVE_SHARED. (SYSTEM_LDSO): Depend on HAVE_SHARED. (DOASSERTS): New option. (UCLIBC_HAS_MMU): Depend on !ARCH_HAS_NO_MMU, rather than just using it to set the default. (HAS_FPU): Depend on !ARCH_HAS_NO_FPU. (USE_GCC_SOFT_FLOAT_OPTION): New option. Rename `Config.v850e' to `Config.v850'. Initial checkin. Improve malloc debugging support. Debugging tweaks. Rename longjmp.S to __longjmp.S Remove extra weak symbols defined by ../common/longjmp.c (SSRC): Rename longjmp.S to __longjmp.S (CSRC): Add clone.c whitespace Initial checkin Add multiple-include protection. Initial checkin. Use correct names for dummy crti.o/crtn.o files. Correct license. Pass CHILD_STACK argument to system call (it possibly worked before `by accident', as the function argument is in the same register). Don't use -O0 when DODEBUG is turned on. Add back in PTRACE_SINGLESTEP. Use decimal instead of hex to agree with common/sys/ptrace.h. Reserve stack space for args we pass to __uClibc_main. (free_to_heap): Unlock the heap before returning in the __UCLIBC_UCLINUX_BROKEN_MUNMAP__ case. Fix from YYang1(a)Winbond.com.tw. (__libc_open): Fix wacky indentation. (1) Make UCLIBC_CC env var work even if __UCLIBC_CTOR_DTOR__ isn't defined. (2) Add a command-line option --uclibc-cc with the same functionality. ansidecl.h and symcat.h copied from glibc. Make sure static heaps are aligned correctly. Add dependencies on header files. Make sure we don't allocate too little space for static free-areas because of our fiddling with alignment (because doing so is VERY BAD). More fiddling with static free-areas: make sure both their size _and_ their alignment are correct. Revert to using uClibc-specific c-symbol-prefix stuff (__C_SYMBOL_PREFIX__). Don't set errno if for zero SIZE returns. Code formatting cleanup. Code formatting cleanup. Mirko Vogt (2): avoid using c99 syntax _vfprintf.c: use 'fputws_unlocked(S, F)' instead of 'fputws(S, F)' Mischa Jonker (2): libc: Fix common-generic stat.h for BE libc/sysdeps: Fix common-generic stat.h for BE part 2 Natanael Copa (23): ldso: initialize stack_chk_guard after TLS is initialized define local stack_chk_guard for nptl fix typo that sneaked in with 9a7506 Fixes NPTL build on x86. nptl/sysdeps/unix/sysv/linux/i386: cleanup -DUSE___THREAD nptl: proper soname handling utils: fix install prefix for getconf utils: Fix ldd segfault nptl: do not define _POSIX_SPAWN since its not implemented nptl: fix static linking config parser: do not assume that realloc return same pointer getservice: getservent_r must return ERANGE when buffer is too small config parser: always initialize line pointer parse_config: discard rest of incomplete line getservice: fix handling of long lines getnet: simplify alias handling and reduce MAXALIASES getproto: increase line buffer size, simlify and fix alias handling ntpl: fix static linking by not leaking SSP_ALL_CFLAGS libc: fix strtoq create DEVEL_PREFIX/MULTILIB_DIR dir rather than DEVEL_PREFIX/lib getaddrinfo: allow numeric service without any hints sys/queue.h: update to eglibc version i386/bits/syscalls.h: allow immediate values as 6th syscall arg Nathan Sidwell (2): Fix a problem with scanning wide chars. Fix some fragileness in dlopen/do_dlopen wrapper & worker pair. Ned Ludd (17): initial commit of uclibc equiv of glibc getent misc cleanups of __stack_smash_handler() function when ssp support is enabled. syslog() support should now work both inside and outside of chroots. erandom code left in but remains #ifdef out by default. May remove erandom completely in the future for uClibc unless the LFS guys and gals want to keep it. misc cleanups of __stack_smash_handler() function when ssp support is enabled. syslog() support should now work both inside and outside of chroots. erandom code left in but remains #ifdef out by default. May remove erandom completely in the future for uClibc unless the LFS guys and gals want to keep it. update : $ - Added support for 13 new syscalls to allow more things to compile when using uClibc. mincore() and the ones for Extended Attributes setxattr(), lsetxattr(), fsetxattr(), getxattr(), lgetxattr(), fgetxattr(), listxattr(), llistxattr(), flistxattr(), removexattr(), lremovexattr(), fremovexattr() which are optional. - dont use dos format - added LD_TRACE_LOADED_OBJECTS to be stripped from the env on suid exec - add patch from Peter S. Mazinger to allow selecting the fast access canary for propolice/ssp - ifdef uselib update from bug #0000013 - ifdef bdflush update from bug #0000011 - updated getent script to match behaviors of newer glibc getent. update from Peter S. Mazinger - 1/NN patches for ssp - 2/NN patches for ssp. Updates from Peter S. Mazinger and Robert Connolly - 3/NN patches for ssp. Doc updates from Peter S. Mazinger and Robert Connolly - avoid segfaulting when rlimit stack is set to low for gen_wctype by calling setrlimit(RLIMIT_STACK, &limit) - added externs to keep gcc quiet about implicit declaration of 3 functions - keep gcc-4.x happy Nitin Garg (1): arm: fix the static link problem for ARM due to undefined __tls_get_addr Paul Mundt (26): Add some more SH relocation types. sh64 ldso updates and fixes. mq_* interfaces are available in librt, remove from unimplemented list. Simplify PERFORM_BOOTSTRAP_RELOC() default path. Add sh2a support. Move sh64 to its own config so we don't crap up the sh one.. SH-4 has nommu variants, whereas SH-3 does not. Fix __sigprocmask weak symbol resolution with gcc4. Fix platform URLs, though I'm sure rmk has enjoyed the extra traffic.. Fix trapa value for _syscall6() to conform with new sh syscall ABI. ARM1136JF-S support. Bogus page size comment for frv PAGE_SHIFT. Bump SHMLBA up to a sensible size for dcache alias avoidance to coincide with the kernel's get_unmapped_area() behaviour. Ideally this should be more tightly packed based off of the L1 dcache shape, once we're able to handle it through the auxiliary vector. Merge SH-2 trapa fixups from Mark. sh crti.S needs features.h to resolve __HAVE_SHARED__, trivial patch from Carmelo Amoroso <carmelo73(a)gmail.com>. Fix PLTJMP() token pasting build error, patch from Carmelo Amoroso <carmelo73(a)gmail.com>. Sync sh's procfs.h with glibc, fixes gdbserver. Patch from Carmelo Amoroso <carmelo73(a)gmail.com>. Bring sh64 support back from the dead. sh64 uses a 32-bit ABI, don't bother with lib64 silliness. Switch sh64 to use __uClibc_main and the new register layout. Update the TODO reflecting the sh64 changes. Disable -msoft-float usage on SH, gcc doesn't support it. Fix up an msync() redefinition for linuxthreads + nommu systems, common case depends on __ARCH_USE_MMU__, falling back on the include/sys/mman.h:msync() stub otherwise. Kill off the GOT lookup for init/fini in the sh crti.S. This was inversely conditional on __HAVE_SHARED__, which has been broken since the time it was copied in originally. The compiler properly generates the GOT references on its own, negating the entire purpose for the init/fini reference. Fix up memset() argument ordering in open_memstream(). Previously parts of the buffers were not being zeroed out as expected. Reported by Dmytro Gorbunov <dmitro.gorbunov(a)gmail.com>. Use __SH_SYSCALL_TRAP_BASE for pthread vfork trap, as it will change depending on ABI. Peter Griffin (2): sh: Fix FPU config option sh: Change __HAVE_SHARED__ to __PIC__ Peter Kjellerstedt (67): Do not assume a fifth argument is used with syscall(). Allocate stack for saving SRP separately. Synchronized with glibc (2.3.2). Use the inlined __dl_parse_dynamic_info() in DL_BOOT() for CRIS too. Corrected a typo. Made it possible to make utils when $(CROSS) or $(CC) contain spaces. Make it compile for architectures which have __UCLIBC_HAS_LFS__ defined, but neither __NR_fadvise64 nor __NR_fadvise64_64. Use Makefile if statements rather than their shell counterparts. Avoid compiler warnings. Use $(LN) rather than ln. Include features.h (without it, testing for __UCLIBC_HAS_THREADS__ makes no sense). Implement _start completely in assembler. Otherwise the compiler will push the frame pointer when DO_DEBUG is enabled (and thus incorrect argc, argv and envp will be passed to the program). Define va_copy for pre-C99 compilers (code taken from vfprintf.c). Made it compile again (and it even seems to work). A little whitespace clean up. Corrected a typo (exection -> execution). Let mconfig support options specified using the menuconfig directive again (this code snippet seems to have vanished somewhere between the original Linux 2.6 kconfig code and here). Copy vendor/linux/2.6.11/scripts/lxdialog to trunk/uClibc/extra/config/lxdialog. Updated to match Linux 2.6.11. The list of source files was just too much. Especially trying to keep it alphabetized (which was not fully successful) made adding a new file a mess. Replaced it with a call to the make function $(wildcard). Updated to match glibc 2.3.4 (adds missing CLOCK_MONOTONIC). Added support for clock_getres() and clock_settime() in addition to the already existing clock_gettime(). In addition they will now use the corresponding system calls if they exists, which resulted in a move to libc/sysdeps/linux/common for clock_gettime.c (it was previously located in libc/misc/time). Added a CRIS specific version of termios.h. It is identical to libc/sysdeps/linux/common/bits/termios.h with a couple of CRIS specific baud rates added. * Allow baud rates above 115200 again. * Added a couple of esoteric CRIS specific baud rates. Sync with glibc 2.3.6. No longer needed. Cleaned up the assembler code a little. Remved the (BROKEN) tag from the CRIS architecture. * Made it possible to dynamically check for supported linker options using the check_ld function. * Only use --warn-unresolved-symbols with linkers that support it. Made include/bits/pthreadtypes.h compile again as it uses struct __sched_param. Made it possible to build without stripping the binaries. Silence link creation. Corrected a typo (simularly -> similarly). A little clean up. Allow MMAP2_PAGE_SHIFT to be specified by the architecture specific header files. Specify a correct MMAP2_PAGE_SHIFT to use when calculating the offset for mmap2() on CRIS. Corrected a comment regarding mmap2(). Include bits/uClibc_page.h before dl-syscall.h as the latter may need the defines from the former. Moved the definition of MMAP2_PAGE_SHIFT from ldso/ldso/cris/dl-syscalls.h to libc/sysdeps/linux/cris/bits/uClibc_page.h where it belongs. A little clean up. * Include sys/syscall.h so __NR_mmap2 and _syscall6 actually have a chance of being defined (the lack of this include probably means that the common mmap64() function has never worked as intended...) * Include bits/uClibc_page.h to get MMAP2_PAGE_SHIFT for architectures that need to define it. A little clean up. Added support for the new CRISv32 architecture. Fix the _syscall6() macro (I hope). Make execle() and chown() available again (corrects commit 15179). Sync with glibc. Remove uses of all QUEUEDEBUG_* macros. Use tar rather than cp to copy all files matching *.so.* from the lib directory to $(PREFIX)$(RUNTIME_PREFIX)lib. The reason for this is that cp -P means wildly different things depending on the version of cp. A little whitespace clean up. Added a missing baud rate (614400) to the speeds[] table. Made it compile again. Allow the res argument to clock_getres() to be NULL. Remove code to define errno in this file. It is definitly not needed when building with thread support (which we normally do), and as far as I can tell it should not be needed otherwise either. And as it did not build with the latest binutils and gcc, the choice was easy... Added support for sysconf(_SC_MONOTONIC_CLOCK). Do not include tls.h unless __UCLIBC_HAS_THREADS__ is defined. Make strdup() use memcpy() rather than strcpy() to duplicate the string. The rationale is that we already have the length of the string to duplicate (from doing the malloc()), and memcpy() should then always be faster than strcpy() (or at least as fast). Recognize _SC_MONOTONIC_CLOCK in sysconf() even if __NR_clock_getres is not defined. Make sure struct stat is identical to struct stat64 if __USE_FILE_OFFSET64 is defined. This was the case for all architectures except those that use packed structures by default (i.e., CRIS). Do not produce spurious "/bin/sh: [: too many arguments" if $(HEADERS_BITS_SUBARCH) is empty (which it most likely is). Patch by Ricard Wanderlof <ricardw at axis dot com>: * Add configurable buffer sizes for getpwnam() and getgrnam(). The default buffer size is, as before, 256 (glibc seems to use 1024 by default). Made it compile again. Restored indentation. Added optimized versions of strcpy() and strncpy() for CRIS/CRISv32. Use poll() rather than select() if the former is available to wait in __dns_lookup(). This avoids segmentation faults when more than 1024 file descriptors are used by an application. Include sys/syscall.h since we are checking for __NR_clock_getres. Correct _init()/_fini() for CRISv32 as suggested by Stefan de Konink. Rebased the memcpy() and memset() implementations for CRIS on the versions found in newlib rather than the ones found in glibc. This should make them smaller and (hopefully) make them compile with newer versions of gcc. Make sure __hot and __cold are always defined. Peter Korsgaard (3): don't make __errno_location / __h_errno_location hidden sync bits/socket.h PF_* / AF_* values with 2.6.38-rc3 bits/time.h: sync with glibc 2.16 Peter S. Mazinger (1307): correct some typos enable flockfile and friends if threads are not enabled remove unused headers on install and clean up all thread related ones disable obstack_printf in header, not supported include headers only if the related option is enabled utils should be built all the time (iconv), disable building readelf do not recurse into subdirs if related options are not set add attribute_relro, should be unconditional, if gcc/ld supports it Makefile cleanups weaks moved after the related function so gcc4 won't warn split out nearbyint, round, trunc from libm/powerpc/s_modf.c no check needed in libm/libpthread, we do not recurse anymore if the related option is not set, more Makefile cleanups Don't remove libc-internal.h on install, else gcc does not build New ssp code using syscalls where possible. Moved guard_setup to __uClibc_main.c, the only place where it is called. Removed SIGKILL option, not usable with sigaction. Changed ssp.c license to LGPL and added vapier as contributor Do not build __uClibc_main.o with ssp enabled Correct targets install_dev and install_runtime to depend on shared Add __cxa_atexit and __cxa_finalize, thanks to Stephen Warren. This patch breaks compatibility with existing binaries, unless the new COMPAT_ATEXIT option is enabled. remove unneeded ';' and add utils to .PHONY Revert earlier patch to install_dev and runtime targets. Need a better solution. Remove created objects independently of TARGET_ARCH and kill 3 warnings Speed up clean target, don't recurse where possible, remove unneeded actions Target distclean removes now locales.txt/codesets.txt too. reorder clean target. Do not create libc.so linker script if only development headers are installed Provide atexit() for static builds Check for existing libc.so ld script before trying to modify it Should correct ppc compilation failure reported by Glauber de Oliveira Costa. Couldn't test it though on ppc. Remove ar-target and shared targets, at build time now we traverse the tree only once. Generalize all toplevel makefiles. Make sure, that libdl.so is built against libc.so and not libc.a Oops, libc.a didn't got installed arm/crt1.S needs features.h and the weak _init/_fini independently of __PIC__. Add these weaks to mips/crt1.S as well. Build crt[in].o with disabled ssp. If HAVE_SHARED is disabled and libm/TARGET_ARCH does not exist, subdirs does not resolve to anything, not pulling in libm.a target. Add libm.a to all: . Modify libm's Makefile not needing any recursion Allow parallel building in libm Remove unneeded temporary file, libm.so will wait until libm.a target is finished Similarly to libm, remove recursion from linuxthreads. Now only libc.a and libc.so are rebuilt again if make is run a second time. Add .type _init/_fini unconditionally to arm/crt1.S Split out header installation into separate install_headers target and added an additional condition for libc.so linker script creation checking for libc.so.0 in place. Move arch specific bits from linuxthreads' Makefile to linuxthreads/sysdeps/TARGET_ARCH/Makefile.in proposed by vapier. The current implementation should suffice for now, but it needs to be extended for the nptl tree. chroot_realpath.c is a dependency also for target ldconfig Add gcc-4.1 non-TLS __stack_chk_guard support. Run the guard setup only once. Move _dl_protect_relro after INIT to allow using attribute_relro within uClibc_init Enable attribute_relro on __guard and __stack_chk_guard now that ld.so supports it Move _dl_protect_relro as in ldso.c, thanks to jocke Do not recurse into ldso/libc/libpthread on clean Use PTDIR in libpthread/Makefile too, add new PTNAME being nptl or linuxthreads. sjhill, I know you kill my keyboard, but please read my added comments, thanks. Add another comment Remove *.o and *.os running find only once Doing the compile in one step creates smaller archives, libcrypt.a shrinks from 12k to 10k, libutil.a to 8k to 4k. Use make provided features where possible /$</$^. User strong_alias instead of initializing __guard separately Sync unsecvars.h w/ glibc-2.3.5, remove unused vars in uClibc, update comment about those in glibc Remove TMPDIR from glibc's commented list Allow building uClibc w/ make-3.79.1 if SSP is disabled Undo size optimizing patch that does not work with gcc-4.1-head, reported by sjhill, thanks cow for testing Missed OBJS definition in libcrypt/libutil. Use := where possible Do not defer expansions where useless, like CSRC/OBJS/LIB_NAME/AR_LIB_NAME, defer only for shared lib related stuff, because it is optional. Run STRIPTOOL only once. More use of /$^/$<. Defer SHARED_START/END_FILES. They are only used for the shared library. Change __OPTIMIZE__ > 0 to defined(__OPTIMIZE__) as in glibc-2.3.5. Rewrote almost all Makefiles: do not use strip $(x),y; run strip on all objects at once; use :=//$</$^; use CRT_SRC/CRT_OBJ/SCRT_OBJ/CSRC/COBJ/SSRC/SOBJ/MSRC/MOBJ where no more is needed, if only CSRC is present use OBJS directly instead of COBJ; CTOR_TARGETS are created directly in lib; remove unused/unneeded parts. Hope I haven't broken too much. Curious failure now, haven't touched this one. Remove /dev/erandom support, as [h]lfs does not use it in this form. Add new rules file for review, better ideas, not used yet Do not recurse into ldso if HAVE_SHARED is disabled. Change __LIBDL_SHARED__ to SHARED. This will be also used in some other places to get an object built for lib*.so but not for lib*.a. Forgotten to commit libdl.c, change __LIBDL_SHARED__ to SHARED. Add -combine to CFLAGS so gcc-4.1 won't build faulty libs if all sources are built into one object This file is a temporarily used one, until all the tree is converted to new structure, allowing to build out of source tree, PIC for shared/ non-PIC for static, allowing to add objects from one lib to the other (needed for ld.so/libc.so and probably libpthread.so) Undo -combine addition, check_gcc can't cope with it Update upcoming new infrastructure files Commit first Makefile.in as example how the new infrastructure is intended to be used Typo correction, thanks cow. Updated libcrypt example Makefile 2 more examples that show the handling of different objects in lib*.so and lib*.a, also handle arch specific optimized versions Add the current implementation to review Add the linuxthreads Makefiles too Adapted generic file to work properly with linuxthreads Update license file to Lesser GPL v2.1 headers is prerequisite for subdirs linuxthreads_db depends on PTHREADS_DEBUG_SUPPORT Change in_addr_t inet_aton to int, glibc has it as int and uClibc uses it in addr.c also as int. Rename mylock/LOCK/UNLOCK in resolv.c to allow IMA compiling Better solution to duplicate locking defines Remove duplicate locking defines for IMA compiling. Kill warnings if IMA compiling Move GETXXKEY_R_FUNC into a separate file to allow IMA compiling Workaround to allow this directory to IMA compile. Someone w/ better understanding, please try to rework this by using only one copy of sp_off Kill warning if IMA compiled More IMA compiling Correcrt posix_fadvise* to allow compiling Use local copy of sysdep.h Make use of fcntl64 syscall if possible All Makefile.in's. Only arm/i386/mips/powerpc/x86_64 are done, the other archs lack proper crt1. The Makefiles in extra/scripts are intended to be linked into each dir, where it is necessary to build locally. Add -fcombine check to allow IMA compiling w/ gcc 4.x Add script to create the minimal subset of symlinks Default changed to IMA compiling, disabled explicitely where currently not possible. Add clean targets for linuxthreads[_db]. Remove s_ceilf.c and s_floorf.c, ceilf and floorf are provided by the float_wrapper. I hope that __ceilf and __floorf are not needed anywhere. Use only __finite from s_finite.c, disabled in fpmacros.c. Allow IMA compiling, 2 files: s_lib_version.c and w_cabs.c have to be reworked for complete IMA. Correct w_cabs.c so it can be added to IMA, add -D_POSIX_MODE for compiling s_lib_version.c (only in the new Makefile) Remove comment, I corrected the order already. Correct header cleanup, if threads are disabled, thanks to Jan-Benedict Glaw reporting it. Hope to catch --combine flag properly on all gcc versions Moved the use of --combine to CFLAGS, we need it for debugging too Moved guard_setup to dl-osinfo.h (used commonly by ldso and libc). Renamed to _dl_setup_stack_chk_guard, as in glibc. SSP requires now binutils-2.16.1 and newer. Add NOT_IN_libc/IS_IN_libc. Began using -DSHARED in uClibc_main.c, there are more candidates in there. Move back dl_protect_relro to it's earlier place. Allow using ssp w/ current active Makefiles too. Build crts for non-shared archs too. ARCH_HAS_NO_MMU implies/selects ARCH_HAS_NO_LDSO frv seems to be an exception having no MMU, but using ldso HAVE_SHARED depends on \!ARCH_HAS_NO_LDSO, remove BUILD_UCLIBC_LDSO and replace the dependencies w/ HAVE_SHARED Missed one occurence of BUILD_UCLIBC_LDSO Remove HAVE_NO_SHARED where ARCH_HAS_NO_MMU/ARCH_HAS_NO_LDSO are selected already Enforce DOPIC, if text relocations are not allowed Remove unused CFLAGS_NOPIC, use ?= some of check_gcc won't rerun Renamed arch specific Makefile.in to Makefile.arch, else if TARGET_ARCH does not exist, we reinclude the including Makefile. Moved arch/common fpu_control.h link creation into main Makefile.in. Updated the link creation script to remove all the other Makefiles We use svn, do not look for cvs related files in distclean Backport to current build system Use consequently headers-y and headers_clean-y, try avoiding TARGET_ARCH use in main Makefile.in Add newly needed Makefiles that can be linked Remove binutils-2.16.1 dependency for SSP, now it works with any binutils, but all apps linked against libc.so will get DT_NEEDED for ld.so too Backport handling of AS_NEEDED Update/add scripts' copyright Remove --exclude CVS from tar Oops, missed commiting AS_NEEDED check Correct building locales and backport the changes typo s/notdir/dir/ Kill a warning. Change __wcstofpmax to __wcstofpmax_l where appropiate Change Makefiles that are not fully IMA to allow it to be used w/ a DOMULTI config option Add configure option to allow IMA compiling Limit IMA compiling to gcc-4, gcc-3.4.4 can't cope w/ some sources Add -o /dev/null to AS_NEEDED check linker script check, else a.out polution all over the place Renamed script to create_makefiles.sh, copy instead of link (to allow cygwin users to build), creates all Makefiles now, should be only used if the master copies are updated Replace all Makefiles for new build infrastucture Hopefully correct undefined __libc_stack_end issue Do not add PICFLAG to generic CFLAGS, this is done based on suffix to .os/.oS (Makerules) Add another Makefile example that will be copied over the root Makefile, adapt script Remove last unused references to libc-a-pic-, we use only the lists in libc-a-y for objects that go into static libs, changing their suffix to .os, of they should be PIC ASFLAGS does not need to include CFLAGS as well, compile.S does it already Update alpha to new builds Update sh to new builds Update sparc to new builds Correct gcc-4.1 ssp build Add back -L..lib to libdl linker, now that we do not hardcode path to libs in libc.so Add check, so we are sure that the file is correctly built, if the system is ssp enabled Split up the .o and .os rules, so all the sources are created if DOPIC is disabled. Only because of multi sources I had to touch up these and add code duplication Create the lib*_pic.a links only if DOPIC is enabled ldso powerpc changes ported to i386 include Rules.mak after noconfig_targets, else it does not pull in .config Allow sources using syscalls to be IMA compiled on x86 Move __SSP__ check to header Enable IMA compiling now that syscalls work Clean up DOMULTI for libm and add more files blocked earlier by syscall problem to libpthread Remove __set_errno proposed by jocke Cleaner i386/syscalls.h patch to handle macro redefines proposed by jocke Added cris on request to new build structure. It has to provide crt1.S instead of crt0.c to get it working Undo 12115, it fails on building libc/sysdeps/linux/common add dummy loop to kill gcc warning, probably _exit should get attribute_noreturn Mark _exit as noreturn, include/unistd.h does this already Allow partly IMA compile of this directory Enable IMA on i386 Enable IMA on libc/string/generic Enable IMA Enable IMA Correct IMA Enable IMA Enable IMA Sync headers w/ glibc wait4 is pid_t, not int Sync with glibc Correct _getdents[64] and __syscall_ipc Last bits for IMA, now everything can be built w/ DOMULTI=y on gcc-3.4.4 with my config (no locale, the rest enabled). Not tested if libc is complete and usable. All the files listed in *_NO_MULTI need love, best would be to replace all multisources w/ single sources.

Change the only bcopy user to memmove and remove internal version of bcopy Remove arch specific hidden bcopy Too many sparc versions ;-(, another hidden bcopy removed make it build if WCHAR is disabled Enable -std=c99 if supported, this will define __STDC_VERSION__, have to -D__ASSEMBLER__, bug in all gcc Sync w/ glibc another attempt to fix sendfile64 make regex a little bit smaller some more prototypes back to inline, mips fails Undo -std=c99 and related -D__ASSEMBLER__ Add IMA compiling strlen is -cheaper- then strnlen don't include wchar.h if WCHAR is disabled include math.h to get the prototype s/IS_IN_linuxthreads/IS_IN_libpthread/, some prototypes, correct Makefile.in, disable __res_state, unavailable in resolv.h New linuxthreads builds on x86, vapier: pt-allocrtsig.c is missing from sources pt-allocrtsig.c is irrelevant for now, remove related too, add libc_hidden_proto from old version change strong to weak_alias, arm fails, thx Khem Raj add comment to know why it's weak s:THUMB_INTERWORK:USE_BX:, thx Khem Raj correct __uselocale __pthread_exit is noreturn only within libpthread same in old remove hidden versions of bzero, unused in libc.so typo global data uses libc_hidden_data_def, convert all -I hope- and add some new change asm/volatile to __x__ gcc41 does not like this at all weaks for __pthread_internal_tsd* are added if not built w/ -DSHARED, header issue Go __malloc_lock, go ... I will risk this one: __curbrk missed two __curbrk everything uses now CFLAGS, no need to add anything to CPU_FLAGS, add -DSTATIC for those not needing shared libs, needed to be seen in libc-symbols.h Use -DSTATIC and remove stub_warning, not accepted Make it build w/ HAVE_SHARED disabled and SSP enabled missed another global data marking fix typo s/__initbrk/__init_brk/ prototype was wrong, change not tested even the hidden version of the weaks in libc (as strong in libpthread) have to be weaks Use internal versions of strchr and stderr for non-BCC getopt_long[_only] visible only if GNU getopt used err() is not used internally Hide internal wrapper Use write instead of __libc_write for debug, hide __td_debug hide __td_agent_list add -DNOT_IN_libc disable hidden_proto/def for __BCC__ generally attribute_hidden is enough in the prototype, sync getopt-susv3 w/ gnu Weaken libc's hidden fork versions, ltp test failed Dont link and remove link.h Sync w/ glibc Add internal hidden_weak support for asm Remove unused files Rename some files, that will conflict w/ IMA Remove unused file More renames for IMA Don't compile arc4random if option not set More renames for IMA Remove unused files Remove unused file Remove it, it's the same as the generic one in ../common Remove vfork.c from Makefile as well Don't compile daemon.c at all for non-MMU Add files for IMA. Yes, I know it's a hack and no, I won't split the affected files Disable deprecated stuff in new linuxthreads Add back the 115200 limit s/#if/#ifdef/ Weaken all internal vfork versions in asm code, wondering why only some of the archs fail Mark some as GNU extensions get_current_dir_name is GNU extension as well Weaken all that I remember being used in libpthread Remove unused prototypes Update some copyrights Mark functions as GNU extensions Remove __x Do not default to _POSIX_MODE environ is GNU extension libc-{a,so,multi}-y replaced by libc-y covering common objects both in libc.a/libc.so, the diffs go into libc-static-y/libc-shared-y exclusively, add IMA to libc, don't use any MSRC anymore Rename _mmap.c to mmap.c so that vax does not pick up both common and arch specific mmap Correct building objs in each libc subdir some test uses ldd, make check depend on utils guard *printf_function w/ UCLIBC_HAS_GLIBC_CUSTOM_PRINTF remove fstat jump reloc Add prototypes Use <> instead of \"\" Reorganize a bit for IMA Move hidden prototypes to proper place and get rid of duplicate hidden Block the combo DOMULTI/SUPPORT_LD_DEBUG DOMULTI may be used for libc, the excluded files need work, linuxthreads[_db] as well, don't try on slow box Kill 2 signedness warnings get rid of __pipe hide xdr_u_short strcoll for non-locale Remove __P(), reorder so that gcc-4.0.2 does not fail w/ multi Change collated_compare/prefix_array to __x hidden, shrinks glob64 from 2352 to 2063 Guard __pthread_mutex_* to be used exclusively within uClibc, do we need this header at all installed? Undo earlier change and sync new linuxthreads' guard w/ old It's not my day .. Sync w/ glibc, no size change Remove hidden_data_def for opt* Take getopt from glibc, disable -W foo support as in the earlier version, size shrink 5%, hope it solves option parsing w/ busybox tar Solve sendfile64 conflict if __NR_sendfile64 does not exist Sync w/ glibc, we can leave __USE_ATFILE in, because we do not define it in features.h All sources are accessable as they would be splitted Sync w/ glibc, enabled only those defines, that are used in uClibc Make use of bits/sched.h We need hidden vfork, not __vfork Remove __clone, add it only back, if threads has a another (strong) version, that needs to overwrite this guard parts w/ __ASSEMBLER__ to be usable in vfork.S Correct ifndef __ASSEMBLER__ exclude 2 files from multi if XLOCALE enabled exclude 2 more files from multi guard program_invocation_name w/ __ASSEMBLER__ wcscoll_l.o does not exist Add support for CFLAGS-OMIT-file from nptl Move -Os/-O2 first, add some gcc4 specific optimizations Make use of CFLAGS-OMIT-file Sync w/ nptl Sync w/ glibc, disabling *at interfaces Correct typo Move common parts into internal header, should it be used for all *64.c? Remove TOPDIR guard __ignore_x correctly, move undefs to their proper place, add prototypes. Should I do all the other *max aliases as well Correct comments Do not use __XL_NPP macro Move lseek64 into LFS guarded place glob depends on fnmatch Move _lfs_64.h to include and adapt files Define internal readdir*_r() and use _lfs_64.h Use _lfs_64.h in all *64.c Remove unneeded hidden_proto(readdir*) Use _lfs_64, reorganize a bit, why did stat*fs64 use stat*fs? Don't build glob64 for non-LFS Get rid of redefines on ppc pointed out by vapier Remove explicit compile rules Disable parts not supported by (outdated) glob, probably the glob[64]_t structures are wrong too Rich Felker's glob() ported to uClibc Add hidden version for susv3 getopt Add Rich Felker's getsubopt, smaller then the glibc copied one Add Rich Felker's getopt_long to be used in conjunction w/ the SuSv3 getopt Provide hidden sigprocmask, remove __x version Remove files not used on target Mark __syscall_*sigaction hidden and add guard to the header freelocale() and strxfrm_l() exist only if XLOCALE is enabled Cleanup/sync w/ glibc Sync w/ glibc Sync w/ glibc and define _STAT_VER/_MKNOD_VER to 0, else some apps will consider versioned stat/mknod in uClibc update typo copyright update Update copyright Remove duplicate include Update copyright Add -D__ASSEMBLER__ to compile.S so that -std=c99 would not fail Add support to remove a flag from CFLAGS Add AT&T research regex testsuite Move regex tests to their own subdir and dont run them if regex is disabled Add CFLAGS-OMIT support to glibc targets for now being the same as for uclibc targets, adapt regex Add another test, use for those hanging -c Move hidden test file for tst-regex2 as well Remove CFLAGS-OMIT support, rename getline to get testregex compile w/ -D_GNU_SOURCE Mark parts as unsupported by gnu glob, but leave it as it was Add --gc-sections, saves 2k on libc.so Upstream update Rename getopt_long-susv3 to -simple check_ld takes only 1 arg as pointed out by pkj disable tst-gnuglob, it has no chance w/ our gnu glob Add UCLIBC_HAS_SSP_COMPAT option guarding gcc-3.x ssp support Remove additional endif pointed out by vapier getopt_long-simple behaves as gnu getopt if POSIXLY_CORRECT is set, adapt test Add back sjhill's 14625 commit, correcting the typo that made it fail Remove __libc_internal_tsd_{s,g}et, they do not exist anymore Get rid of nested extern warnings if threads are disabled uClibc_pthread.h wasn't ever included Add support for libpthread_nonshared.a, strip the objects in *nonshared* Add common part of linker scripts to a file and make use of it Create libpthread_nonshared.a Remove unneeded ; after *_alias Move __clone/__uselocale to uClibc_glue.h Get rid of forwarded __pthread_attr_init Not the best idea moving libc_hidden_proto to uClibc_glue.h Sync w/ upstream, hide pthread_atfork Use GNU features only if defined in header Disable --gc-sections until I find why it is ignored on some configurations Add back XLOCALE for hidden uselocale try to get libpthread built w/ -DSHARED, what to do w/ _dl_load_lock? Add comment why --gc-sections is ignored Remove duplicate hidden __curbrk (ppc), make use of the hidden versions Remove all non-constant libc_hidden_data_def(), it is too unreliable, sorry, most of

pthreadP.h for SIGCANCEL epoll.c: add cancellation to epoll_[p]wait() update arc4random from bug #885 remove cris/fork.c, unused remove sysdep.h from arch specific string implementation remove arm specific sysdep.h from linuxthreads new Phil Blundell (1): Fix __libc_epoll_pwait compile failure on x86 Philip Craig (1): Fix memory leak in dlopen()/dlclose(). Philip Nye (1): resolv.c fails for /etc/hosts lookups Randolph Chung (2): misc net fixes for building.... the rest of the compile fixes Ricard Wanderlof (9): CRIS/CRISv32 architecture specific memcpy, memmove and memset. Added support for the AI_ADDRCONFIG flag in the hints->ai_flags parameter to getaddrinfo(3). Fixed #if -> #if defined. Take __UCLIBC_HAS_IPV4__ into account. Removed include/ifaddrs.h and put contents in libc/inet/ifaddrs.h, as we do not need the file outside of uClibc anyway. Simplified check_pf() so it returns a bit vector in an unsigned int, instead of modifying the contents of two bools. Removed redundant includes. Move ifaddrs.h from uClibc-internal location libc/inet/ to include/, and make it conditionally included among the installed header files depending on UCLIBC_HAS_AI_ADDRCONFIG. Remove all references to __no_netlink_support as after thurough scrutiny of the code it was never used in any useful way. File removed as it was not only redundant but also horribly out of date. Richard Braun (3): mips: avoid segmentation fault when RLD_MAP is 0 libdl: add option for controlling dl_cleanup libc: fix signal handling in system() Rob Landley (27): Patch from Jim Gifford (of Cross Linux From Scratch) fixing the Mips failures from Mike's nightly builds. Remove debian directory at the request of Simon Richter. (The debian developers prefer to maintain their own debian subdir as a patch.) Fix a build break due to errno and h_errno being unresolved symbols. (No idea if this is the right fix but it's something for now.) svn 17941/17943 broke the build. 18032 made the threaded case compile again, this makes the non-threaded case compile again. I have no idea if this is the proper fix, I'm just tired if it not compiling for two weeks. Patch from Khem Raj that fixes running gcc on arm for me. (Otherwise it says "virtual memory exhausted" trying to build hello world.) Patch from Al Stone to fix ia64: Be consistent about spelling. LGPL says "License" not "Licence", so go with that. (Spotted by Xride on irc.) No configs actually set LIBGCC_CFLAGS to anything, and it's not even written into the resulting .config, so remove it. Have Makefile.in call conf-header.sh instead of having kconfig call it via system(). Also move it to extra/scripts since it's a uClibc build script, not part of upstream kconfig. Adjust the "grabbing a new kconfig snapshot" procedure accordingly. Warning fix for uninitialized variable, by Al Stone. Make the code match the comments. (I narrowed down the bug, Khem Raj pointed out the solution. This fixes a segfault for me on exit from a statically linked "hello world".) Revert last change until we figure out the correct fix. Bugfix from Atsushi Nemoto: return nonzero error code on failure (without which busybox ping segfaults on error). Broken during locking changes in in svn 16801. Make menuconfig help bigger and fluffier. Dependencies tweak: make install should depend on all, or "make -j 3 all install" can't work without two separate invocations of make. Explain what malloc simple is good for, and what it isn't good for. Finally fix the MALLOC=y and MALLOC_SIMPLE=y breakage from svn 23660. (I found it, this is Bernhard's patch to fix it. Tested and it Works For Me (tm)). Current kernels support more than 8 bit major/minor. Pass dev_t through to the kernel unmolested. Mention make utils, hostutils, install_utils. Remove hardwired usr/ from install_utils (that's what $RUNTIME_PREFIX is for) and add install_hostutils. Now install_utils should use $PREFIX more like other packages do. Fix __attribute__ (( __attribute__ ((noreturn)))), which doesn't compile. Make HARDWIRED_ABSPATH a config option. Fix thinko in svn 25434. 32/64 bit sparc got unified in 2.6.29 the way x86/x86_64 did in 2.6.28. The new guard symbol is "__SPARC_POSIX_TYPES_H". Fix fcntl64 for 64 bit targets. sh: fix build for SH in !NPTL case sparc: fix build for linuxthreads.old Roman I Khimov (13): libpthread/nptl_db: define NOT_IN_libc Makefile.in: install sgtty.h libpthread/x86_64: fix clean libc/regex: fix internal_function declarations libc/x86_64: use ELF-compatible definitions for assembler nptl: fix sem_open with O_CREAT nptl: use arch-specific cancellation routines for x86_64 nptl: use arch-specific pthread_cond_timedwait and pthread_cond_wait on x86_64 ldso: fix x86_64 R_X86_64_TPOFF64 and R_X86_64_DTPOFF64 relocations libm: unhide signgam libm: unbreak scalbn for 64-bit processors nptl i686: fix pthread_cond_wait.S compilation syslog: fix 'everyone logs with user facility' Ron (13): Add some missing printf/scanf format attributes Move extern prototype out of function scope Add noreturn attributes to some functions that won't ever do so Make more utility functions static Provide token prototypes for functions that are external but have no header Check #if feature test macros are defined where they may not be Add a few missing includes Don't shadow the err() function with a local var Don't shadow stat with a local variable Don't shadow the mask parameter with a local variable in the same function Don't shadow the chroot global Avoid warnings about shifting more bits than we have Avoid type-punned pointers that break strict-aliasing Ron Alder (2): Fixed the parameters to mmap in malloc. malloc now works, but wastes alot of memory with the minimum amount of memory used for each allocation being 4k. Implimented a simple allocation system that does not waste memory. Added realloc. The allocation system was needed to support realloc. Ronald Wahl (1): libc: atexit: reuse free slots at the end of exit functions table Ryan Flux (2): microblaze has long double support too microblaze mmu/elf/shared lib support Salvatore Cro (11): tests: nptl tests dependencies cleanup misc: utmpx based logging support libubacktrace: Provide uClibc with backtrace functions libc: Fix cancellation handling in some C functions sh: move data without fetching cache block within the memset sh: update the memcpy adding a new loop with aggressive prefetching tests: Added new nptl tests ldso_sh: add support for protected symbols to SH Add protected symbols support for all architectures test: fix tst-tls13 expected result and timeout Added fts support for traversing UNIX file hierarchies. Sedat Dilek (2): Revert "Makerules: respect HARDWIRED_ABSPATH in interp.c" Makerules: Remove duplicated slashes in interp.c Stas Sergeev (1): nptl: sh: fix race condition in lll_wait_tid Stefan Kristiansson (1): vfork: fix clone based version Stephan Raue (1): add timerfd syscall and header Steve Bennett (7): libc.so: include all output formats in linker script Use the generic bits/select.h for microblaze microblaze can be either big or little endian microblaze linux has no SDA support microblaze: add sys/user.h microblaze/bits/setjmp.h: Fix stray #endif string/microblaze: Fix for little-endian Steve Ellcey (9): libc: mips: Fix non-LFS build mips: silence 'set but not used' warnings libc: Fix sync_file_range.c for MIPS64 N32 ABI mips: Remove duplicate macro definitions buildsys: Add MIPS64R2 support libc: fix mips N64 pread/pwrite build Fix warnings in MIPS build Update MIPS configuration rules.

Thorsten Glaser (10): cris: add provide arch-specific vfork implementation make __dl_start, whose address is taken, into a real object type explicitly cast (even though this casting is not very nice) remove apparently unused code, this time for real silence GCC I think this is what you mean shut up GCC fix cast warning shut up GCC, part 2 maybe fix an "noreturn function does return" warning Timo Teras (6): Revert "nptl: mark symbols with libc forwarder hidden" libc-symbols: add attribute_protected libc: remove libc weak __pthreads_* wrappers nptl: mark forwarded functions protected static build: fix internal locking weaks to get pulled in always resolv: various memory corruption and off by one fixes Timo Teräs (27): PIC fixes for hardened nptl/sysdeps/unix/sysv/linux/i386: enable USE___THREAD for assembler nptl: mark symbols with libc forwarder hidden nptl: initialize stdio locking linuxthreads.new: initialize stdio locking nptl: turn pointer demangling off nptl: fix libc sigaction signal checking nptl: fix libc sigtimedwait nptl: remove unneeded libc-lock.h include nptl: fix malloc library locking nptl: fix warnings of shadowing __self ldso: support RTLD_NODELETE and DF_1_NODELETE nptl: fix libc internal, dynamically enabled locking nptl: fix dynamic initialization of libpthread static build: define pthreads wrappers only for threaded builds more workarounds for GCC PR32219 nptl: fix x86 assembly PIC relocations config parser: fix memory corruption nptl: fix calling convention for __pthread_mutex_cond_lock Fix resolver broken in NPTL build libm/x86: use call instead of jump for wrappers nptl: fix Unwind_Resume PLT calls posix_fadvise64: fix x86 implementation ldso: support RTLD_NOLOAD libdl: rudimentary locking for dlopen/dlsym/dlclose dl: fix dlsym lookups with RTLD_NEXT inet: do not filter responses in res_query Tobias Anderberg (36): Fixed another address alignment where a pagesize of 4k were assumed. Support LD_DEBUG=all Initial version of the CRIS port. Added cris to ALL_SUBDIRS Initial version of the dynamic linker code for the CRIS port. Updated for the CRIS port. Configuration for the CRIS port. * Updated for the CRIS port. * Added variable LIBGCC which is included when linking libc.so. Arch specific linker options go into LIBGCC_CFLAGS defined in Config.<arch>. * Added semi-support for version scripts. If sysdeps/linux/<arch>/libc.map exists read it and include it when linking. * Add LIBGCC when linking libc. * Changed paramater names to match their register, i.e. __a -> __r10. * Do not clobber things that are specified as outputs. Removed unused file Added pthread support for CRIS. * Added clone() system call. * Proper implementation of bits/syscalls.h, no cheating by just including <asm/unistd.h>. * Proper implementation of syscall.S, it no longer contains the __syscall_error, instead it contains code which makes syscall(nr,...) a system call. * Added sysdep.S which contains the code for __syscall_error. * Added some macros to sysdep.h. * Added sys/procfs.h, which is needed when compiling with thread support. * Removed unused syscall-cris.c. Build libpthread now that the CRIS as support for it! Removed redundant code. Same thing exist in sys/syscalls.h so include that instead. Cosmetic cleanup. Removed redundant definition of __USE_WEAK_ALIASES. Added option for selecting cris architecure type. For now, only CRIS is available. Added a default configuration for cris. Added CPU_CFLAGS and CPU_LDFLAGS for cris. Added additional CFLAGS for cris when compiling with PIC. Cosmetic changes. Updated CRIS configuration files. Removed CRIS specific code. Cosmetic changes. Added cris to "define list". Added assembler version of startup code. Fix Makefile so it uses the new code. Re-add cris to "define list" when fixing auxvt. Initialize strings as pointers instead of arrays. Corrected LD_BOOT macro * Partial re-write to match other archs and remove duplicate code. * Assign insead of add when doing relocations. Hm. Keep using crt0.c for now. My fever-hack of crt0.S didn't do the expected thing. A so called "D'oh!". Don't forget addend on relocations + minor other fixes. Updated cris configuration. Updated cris configuration; added support for %m. Updated to match the other architectures. Fixes problem with "fcntl: function not implemented". Save r0 before modifying it. Removed unused file. Replaced modulo code with the modulo operator.
