* Adjust mutex lock in condvar_cleanup if we got it from requeue_piSiddhesh Poyarekar2012-10-164-4/+17
| | | | This completes the fix to bz #14652.
* Fix formatting in nptl/sysdeps/pthread/pthread.h.Carlos O'Donell2012-10-101-2/+2
| | | | | | | | The macro pthread_cleanup_push_defer_np in pthread.h has a misaligned line continuation marker. This marker was previously aligned, but recent changes have moved it out of alignment. This change realigns the marker. This also reduces the diff against the hppa version of pthread.h where the marker is aligned.
* Take lock in pthread_cond_wait cleanup handler only when neededSiddhesh Poyarekar2012-10-105-8/+65
| | | | | | | | | | [BZ #14652] When a thread waiting in pthread_cond_wait with a PI mutex is cancelled after it has returned successfully from the futex syscall but just before async cancellation is disabled, it enters its cancellation handler with the mutex held and simply calling a mutex_lock again will result in a deadlock. Hence, it is necessary to see if the thread owns the lock and try to lock it only if it doesn't.
* Add missing magic to GLIBC_PROVIDES.Roland McGrath2012-10-092-202/+0

* Correct libthreadb register access for 64-bit sparc.David S. Miller2012-10-051-2/+2
| | | | | | | [BZ #14568] * sysdeps/sparc/tls.h (DB_THREAD_SELF_INCLUDE): Delete. (DB_THREAD_SELF): Use constants for the register offsets. Correct the case of a 64-bit debugger with a 32-bit inferior.
* Unlock mutex before going back to waiting for PI mutexesSiddhesh Poyarekar2012-10-054-171/+156
| | | | | | | | | | [BZ #14417] A futex call with FUTEX_WAIT_REQUEUE_PI returns with the mutex locked on success. If such a successful thread is pipped to the cond_lock by another spuriously woken waiter, it could be sent back to wait on the futex with the mutex lock held, thus causing a deadlock. So it is necessary that the thread relinquishes the mutex before going back to sleep.
* Update copyright yearsH.J. Lu2012-10-021-1/+1

* Fix clone flag name in comment to CLONE_CHILD_CLEARTID.Siddhesh Poyarekar2012-10-026-6/+6
|
* Fix exception table for i386 pthread_cond_waitSiddhesh Poyarekar2012-10-012-2/+22
| | | | | | | | [BZ #14477] Add an additional entry in the exception table to jump to __condvar_w_cleanup2 instead of __condvar_w_cleanup for PI mutexes when %ebx contains the address of the futex instead of the condition variable.
* Fix bugs in powerpc pthread_once.Alan Modra2012-09-251-5/+16
| | | | | | | | | Ref gcc.gnu.org/bugzilla/show_bug.cgi?id=52839#c10 Release barriers are needed to ensure that any memory written by init_routine is seen by other threads before *once_control changes. In the case of clear_once_control we need to flush any partially written state.

* Allow a single-threaded program to cancel itselfSiddhesh Poyarekar2012-05-151-0/+3
| | | | | | | | | There is nothing in the POSIX specification to disallow a single-threaded program from cancelling itself, so we forcibly enable multiple_threads to allow the next available cancellation point in the thread to run. Also added additional tests to cover various cancellation scenarios.
