[PATCH] xtensa: add custom bits/poll.h
by Max Filippov 14 Dec '18

14 Dec '18

Definitions of POLLWRNORM, POLLWRBAND and POLLREMOVE in xtensa linux kernel are non-standard. Provide bits/poll.h with correct values for these constants. This fixes the following strace build errors: In file included from xlat/pollflags.h:4:0, from poll.c:34: ./static_assert.h:40:24: error: static assertion failed: "POLLWRBAND != 0x0100" # define static_assert _Static_assert ^ xlat/pollflags.h:75:1: note: in expansion of macro ‘static_assert’ static_assert((POLLWRBAND) == (0x0100), "POLLWRBAND != 0x0100"); ^~~~~~~~~~~~~ ./static_assert.h:40:24: error: static assertion failed: "POLLREMOVE != 0x0800" # define static_assert _Static_assert ^ xlat/pollflags.h:117:1: note: in expansion of macro ‘static_assert’ static_assert((POLLREMOVE) == (0x0800), "POLLREMOVE != 0x0800"); ^~~~~~~~~~~~~ Signed-off-by: Max Filippov <jcmvbkbc(a)gmail.com> --- libc/sysdeps/linux/xtensa/bits/poll.h | 49 +++++++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 libc/sysdeps/linux/xtensa/bits/poll.h diff --git a/libc/sysdeps/linux/xtensa/bits/poll.h b/libc/sysdeps/linux/xtensa/bits/poll.h new file mode 100644 index 000000000000..4588cc326006 --- /dev/null +++ b/libc/sysdeps/linux/xtensa/bits/poll.h @@ -0,0 +1,49 @@ +/* Copyright (C) 1997, 2001, 2006 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Re: [uclibc-ng-devel] use safe, even if possibly a few cycles slower, six-argument syscall implementation
by Ata, John (US) 06 Dec '18

06 Dec '18

On January 29,2017 a patch (9b457baf8d46329f7d7ee2aa084022bb0df88551<https://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/commit/?id=9b457baf8d4632…>)by mirabilos m(a)mirbsd.org<mailto:m@mirbsd.org> was accepted in the repository. I have a few questions on this patch. 1) The patch created a new file syscall6.S in the i386 directory. It seems functionally equivalent to the syscall.S. Both process 6 arguments plus the NR. Both use the exact same registers. Only an alignment directive has been added and the order of loading the registers is reverse. It also appears that glib does not have a special syscall6.S. Why did we go this route special casing 6 argument syscalls only? 2) The LOADARGS_6, RESTOREARGS_6 and ASMFMT_6 defines are removed from <bits/syscall.h>. It is not clear why from the patch. 3) There seems to be a deficiency in the syscall setup that is not present in glibc making it impossible to get a backtrace from a syscall. For example, If one looks at uclibs-ng's sysdeps.h in i386, one can see cfi_adjust_cfa_offset/cfi_rel_offset usage in the _PUSH_ARGS_1 and _POP_ARGS_N macros allowing backtrace information to be present on the stack. However, syscall/syscall6.S as well as bits/syscalls.h do not allow for this. In addition, it appears that glibc does have this mechanism in its syscall.S. Thoughts anyone?

[PATCH] Defined INLINE_SYSCALL_NOERR_NCS in mips/bits/syscalls.h
by Volodymyr Boyko 23 Nov '18

23 Nov '18

On Linux/MIPS (O32 ABI) for system call we have two result registers - v0 and a3. v0 contains actual syscall result on success or error number on fail, a3 set to 0/1 for indicating syscall success/fail. (if a3 == 1, v0 contains errno). Now as we can see from definition of handle_sys (arch/mips/kernel/scall32-o32.S), handler treats returned by syscall function (let's call "original") values in range [-EMAXERRNO; 0[ as -errno, a3 is set to 1 and final returned (to userspace) value is (-original). INLINE_SYSCALL_NOERR_NCS defined in mips/bits/syscalls.h will handle this behaviour.

uClibc-ng GitHub mirror
by Alexey Brodkin 21 Nov '18

21 Nov '18

Hi Waldemar, It looks like GitHub mirror is a bit out of sync with your main repo. See https://github.com/wbx-github/uclibc-ng/commits/master was last updated back in August. Also I noticed that the most recent version 1.0.31 is not listed in tags in the main repo: https://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/refs/tags. -Alexey

SIGSEGV on pthread cancelation
by Александр Усов 30 Oct '18

30 Oct '18

Hello. I faced a problem I can't solve by myself so I will be grateful for any help. This code causes segfault: #include <poll.h> #include <pthread.h> static void * thread_func (void *arg) { int count = 0; struct pollfd pfds[1] = { 0 }; poll(pfds, count, 1000); } int main () { pthread_t thread; if (pthread_create(&thread, NULL, thread_func, NULL)) return 1; if (pthread_cancel(thread)) return 2; if (pthread_join(thread, NULL)) return 3; return 0; } This is how backtrace looks: Thread 2 received signal SIG32. Thread 2: #0 0xb76b24f6 in __poll_nocancel (fds=0xb76a0414, nfds=0, timeout=1000) at libc/sysdeps/linux/common/poll.c:27 #1 0xb76b2585 in __GI_poll (fds=0xb76a0414, nfds=0, timeout=1000) at libc/sysdeps/linux/common/poll.c:208 #2 0x080484c3 in thread_func () #3 0xb77954b0 in start_thread (arg=0xb76ebba0) at libpthread/nptl/pthread_create.c:285 #4 0xb76fcae7 in clone () at libc/sysdeps/linux/i386/clone.S:103 Thread 1: #0 0xb77996f1 in pthread_join (threadid=3077487520, thread_return=0x0) at libpthread/nptl/pthread_join.c:88 #1 0x08048522 in main () Architecture is i386. Interesting thing is that segmentation fault only happens when uClibc-ng built with debug enabled (DODEBUG=y). Thank you.

buildroot uclibc-ng static libm support
by servo gmrt 20 Oct '18

20 Oct '18

Hi, Hi, I am using buildroot for my development work. I build a minimal linux for ICOP VDX6354 board. I am using rtai-4.1 for hard realtime task for my application. I need to link the static libm to rtai_math.ko module to use math function support in rtai. When I use buildroot with uclibc I am able to generate libm.a. But when I try to disassabmle the libm.a it lists lot of unknown symbols. Also when I try to insert the rtai_math.ko it also reports the unknown symbols. Is there any way to build the uclibc static libm.a with all symbols included in it.
