* Extend i486 pthread_cond_timedwait to use futex syscall with absolute timeoutAndreas Schwab2013-01-101-66/+315
| | | | | | * sysdeps/unix/sysv/linux/i386/i486/pthread_cond_timedwait.S (__pthread_cond_timedwait): If possible use FUTEX_WAIT_BITSET to directly use absolute timeout.

* Adjust mutex lock in condvar_cleanup if we got it from requeue_piSiddhesh Poyarekar2012-10-162-2/+8
| | | | This completes the fix to bz #14652.
* Take lock in pthread_cond_wait cleanup handler only when neededSiddhesh Poyarekar2012-10-102-4/+32
| | | | | | | | | | [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.
* Unlock mutex before going back to waiting for PI mutexesSiddhesh Poyarekar2012-10-052-87/+68
| | | | | | | | | | [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.

* 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.
