Memory ordering in pthread_mutex_{,timed}lock.
...
All commits should have happened before the mutex lock is taken.
Therefore use the _rel variant of the cmpxchg atomic op.

Make x86-64 pthread_cond_timedwait more robust.
...
It just happens that __pthread_enable_asynccancel doesn't modify the $rdi
register. But this isn't guaranteed. Hence we reload the register after
the calls.

Implement pthread_sigqueue.
...
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.

Add missing export of fallocate64 on 32-bit platforms.
...
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.

Don't try to cleanup libselinux and libaudit.
...
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.
2009-05-15 20:48:08 -07:00
9437b427ce
Fix change to prevent cancel signal in unsafe places.
...
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.
2009-05-15 20:42:36 -07:00
1a7f254b4b
No cancel signal in unsafe places.
...
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.
