MFC r294515:

2016-01-28T22:57:09Z

Fix the implementations of PSEUDO_NOERROR and PSEUDO. The PSEUDO* macros should not declare , only _ and __sys_. This was causing the interposing C wrappers to be ignored due to link order.

MFC r294565: sem: Don't free nameinfo that is still in list when open()

2016-01-27T22:56:04Z

fails. This bug could be reproduced easily by calling sem_open() with O_CREAT | O_EXCL on a semaphore that is already open in the process. The struct sem_nameinfo would be freed while still in sem_list and later calls to sem_open() or sem_close() could access freed memory. PR: 206396

Revert r279010:

tdelete(3): don't delete the node we are about to return. The original change, from NetBSD, was bogus; introduced a memory leak and and broke POSIX. By reverting we actually match NetBSD's latest revision. This is a direct commit to 10 since this function was rewritten in 11-current.

MFC r294234: utimensat(2): Correct description of [EINVAL] error.
