2012-10-10Fixup nptl/ChangeLog for last commit.Carlos O'Donell
2012-10-10Fix formatting in nptl/sysdeps/pthread/pthread.h.Carlos O'Donell
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.
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.

[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.

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.
2012-09-25Fix bugs in powerpc pthread_once.Alan Modra
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.

2012-07-28Fix tst-pthread-getattr test caseSiddhesh Poyarekar
Get the tst-pthread-getattr fix back with further improvements so that it does not fail on targets that use the user stack to save context.

2012-07-20Fix tst-pthread-getattr test caseSiddhesh Poyarekar
In some cases, the compiler would optimize out the call to allocate_and_test and thus result in a false positive for the test case. Another problem was the fact that the compiler could in some cases generate additional shifting of the stack pointer, resulting in alloca moving the stack pointer beyond what is allowed by the rlimit. Hence, accessing the stackaddr returned by pthread_getattr_np is safer than relying on the alloca'd result. Another problem is when RLIMIT may be very large, which may result in violation of other resource limits. Hence we cap the max stack size to 8M for this test.

2012-06-23SH: __lll_robust_timedlock_wait: Simplify CFI directives.Thomas Schwinge
2012-06-20Account for the extra stack size when rlimit is small enoughSiddhesh Poyarekar
When rlimit is small enough to be used as the stacksize to be returned in pthread_getattr_np, cases where a stack is made executable due to a DSO load get stack size that is larger than what the kernel allows. This is because in such a case the stack size does not account for the pages that have auxv and program arguments. Additionally, the stacksize for the process derived from this should be truncated to align to page size to avoid going beyond rlimit.

2012-05-26Fix stack size and address inconsistency due to executable stackSiddhesh Poyarekar
When a stack is marked executable due to loading a DSO that requires an executable stack, the logic tends to leave out a portion of stack after the first frame, thus causing a difference in the value returned by pthread_getattr_np before and after the stack is marked executable. It ought to be possible to fix this by marking the rest of the stack as executable too, but in the interest of marking as less of the stack as executable as possible, the path this fix takes is to make pthread_getattr_np also look at the first frame as the underflow end of the stack and compute size and stack top accordingly. The above happens only for the main process stack. NPTL thread stacks are not affected by this change.
