* Fix tst-pthread-getattr test caseSiddhesh Poyarekar2012-07-282-22/+74
| | | | | | 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.

* Fix tst-pthread-getattr test caseSiddhesh Poyarekar2012-07-202-12/+50
| | | | | | | | | | | | | | 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.

* Account for the extra stack size when rlimit is small enoughSiddhesh Poyarekar2012-06-204-2/+139
| | | | | | | | | | | 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.

* Fix stack size and address inconsistency due to executable stackSiddhesh Poyarekar2012-05-262-2/+21
| | | | | | | | | | | | | | | 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.

* Allow a single-threaded program to cancel itselfSiddhesh Poyarekar2012-05-1512-2/+290
| | | | | | | | | 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.
