2012-10-10Take lock in pthread_cond_wait cleanup handler only when neededSiddhesh Poyarekar
[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.
2012-10-05Unlock mutex before going back to waiting for PI mutexesSiddhesh Poyarekar
[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.

2012-10-01Fix exception table for i386 pthread_cond_waitSiddhesh Poyarekar
[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.

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.

2012-05-15Allow a single-threaded program to cancel itselfSiddhesh Poyarekar
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.
