2017-05-20	Remove the bulk of the NaCl port.	Zack Weinberg
	The NaCl port has not been actively maintained since before the 2.25 release. The complementary GCC back-end was never contributed to GCC, and we are given to understand that the current NaCl SDK has switched to Clang and therefore cannot be used to build glibc anymore, so we doubt that the port remains useful. This commit simply removes the sysdeps/arm/nacl and sysdeps/nacl directories and the abi-tags entry. Remove the NaCl port. * abi-tags: Remove .-.-nacl.* entry. * sysdeps/arm/nacl: Remove directory and contents. * sysdeps/nacl: Likewise.
2017-01-28	Bug 20116: Fix use after free in pthread_create()	Carlos O'Donell
	The commit documents the ownership rules around 'struct pthread' and when a thread can read or write to the descriptor. With those ownership rules in place it becomes obvious that pd->stopped_start should not be touched in several of the paths during thread startup, particularly so for detached threads. In the case of detached threads, between the time the thread is created by the OS kernel and the creating thread checks pd->stopped_start, the detached thread might have already exited and the memory for pd unmapped. As a regression test we add a simple test which exercises this exact case by quickly creating detached threads with large enough stacks to ensure the thread stack cache is bypassed and the stacks are unmapped. Before the fix the testcase segfaults, after the fix it works correctly and completes without issue. For a detailed discussion see: https://www.sourceware.org/ml/libc-alpha/2017-01/msg00505.html
