2009-06-12Implement pthread_sigqueue.Ulrich Drepper5-2/+102
The kernel from 2.3.31 on supports the rt_tgsigqueueinfo syscall. Use it to implement the non-standard extension which, like sigqueue, can pass additional data to the receiving thread.
2009-06-11Fix futex syscall parameter for x86 absolute timeout waits.Bryan Kadzban2-1/+9
This affects only installations compiled for kernels older than 2.6.18.
2009-05-16libc-cancellation.c cleanup.Ulrich Drepper4-11/+35
The unrelated function __libc_cleanup_routine should not be in this file. Move it into its own file.
2009-05-16Unify source for async cancel handling.Ulrich Drepper4-189/+12
Unify all three places where we enable async cancellation for syscalls. Optimize a bit.
2009-05-16Rename nptl/init.c to nptl/nptl-init.c.Ulrich Drepper3-3/+9
Needed to allow overwriting architectures init.c in csu and nptl individually. Fixes BZ #9924.
2009-05-15ChangeLog entries incorrectly applied.Ulrich Drepper1-25/+0
2009-05-15Add missing export of fallocate64 on 32-bit platforms.Jakub Jelinek1-0/+18
Due to a pasto the fallocate64 interface, introduced in glibc 2.10, isn't exported for 32-bit Linux platforms. It is too late for this now so exported them for glibc 2.11.
2009-05-15Don't try to cleanup libselinux and libaudit.Jakub Jelinek1-0/+7
Because we are not shutting down the other threads first another thread might work on a query before the process shuts down. In this case the now uninitialized libselinux and libaudit might be used. Just don't free the resources. It's not necessary anyway because the process is about to terminate.
2009-05-15Fix change to prevent cancel signal in unsafe places.Ulrich Drepper4-14/+16
The bits tested to decide when to delay the return when switching off async cancel mode were wrong. Fix that. Also close a race condition in pthread_cancel where the bit indicating the cancellation is unconditionally set even if the cancel type might have changed.
2009-05-15No cancel signal in unsafe places.Ulrich Drepper3-2/+32
When disabling async cancellation we cannot return from the function call if the thread is canceled. This happens when the cancel bits have been set before async cancel is disabled but the signal hasn't been sent/received yet. Delay for as long as necessary since otherwise the signal might be received in an unsafe context.
