Status of TLS and NPTL support for noMMU
by Max Filippov 22 Sep '15

22 Sep '15

Hello, I'm trying to build uClibc-based userspace for uclinux. It builds and works as long as I keep uClibc single-threaded. If I enable TLS and NPTL support first I face build errors (one caused by reference to fork from libpthread/nptl/sysdeps/unix/sysv/linux/fork.c, other outside uClibc, in the elf2flt, which cannot deal with .tbss section overlapping .data section) and then runtime errors (an attempt to allocate TLS memory with sbrk which doesn't work in uclinux and then inability to initialize TLS data, which I haven't tracked yet). All that makes me think that either I'm doing something terribly wrong, or TLS + NPTL are not supported by uClibc for uclinux. So my questions are: - are TLS and NPTL supported by uClibc for uclinux? - if not, what are the supported threading options? -- Thanks. -- Max

enabling sigsetmask() support
by Alex Potapenko 16 Sep '15

16 Sep '15

Hi, I'm trying to compile a sourcecode that makes use of sigsetmask() function against uClibc-ng 1.0.6. This symbol is missing from uClibc-ng built with default Buildroot 2015.08 config. Which option should be enabled to have it? I only found two signal options in the config: UCLIBC_HAS_OBSOLETE_BSD_SIGNAL and UCLIBC_HAS_OBSOLETE_SYSV_SIGNAL. The former was enabled by default, the latter was off, but turning it on doesn't help too. I see that sigsetmask() is just a wrapper around sigset_set_old_mask, sigprocmask and sigset_get_old_mask, but I don't want to resort to patching the user app sourcecode if possible. Thanks, Alex

Unwinding info for cancellable syscalls
by Max Filippov 14 Sep '15

14 Sep '15

Hello, I've noticed that several NPTL tst-cancelx* tests fail on ARM, because functions invoking cancellable syscalls are compiled without -fasynchronous-unwind-tables making it impossible for the libgcc DWARF unwinder to unwind stack past the syscall and call the cleanup routine. They work on x86_64, because x86_64 gcc has -fasynchronous-unwind-tables enabled by default, and on xtensa because it uses custom unwinding code. I haven't checked, but AFAIU it should fail on other architectures that use DWARF unwinder. Can anybody confirm that? I guess that at least all functions that invoke cancellable syscalls need to be built with -fasynchronous-unwind-tables in their CFLAGS. I've tried that with couple of functions and it fixes corresponding tests. And that's what glibc does in nptl/Makefile. Does that sound right for uClibc? -- Thanks. -- Max
