2013-07-20	fix shm_open wrongly being cancellable	Rich Felker	-1/+6

2012-09-30	overhaul sem_open	Rich Felker	-3/+3
	this function was overly complicated and not even obviously correct. avoid using openat/linkat just like in shm_open, and instead expand pathname using code shared with shm_open. remove bogus (and dangerous, with priorities) use of spinlocks. this commit also heavily streamlines the code and ensures there are no failure cases that can happen after a new semaphore has been created in the filesystem, since that case is unreportable.
2012-09-30	clean up, bugfixes, and general improvement for shm_open/shm_unlink	Rich Felker	-9/+28
	1. don't make non-cloexec file descriptors 2. cancellation safety (cleanup handlers were missing, now unneeded) 3. share name validation/mapping code between open/unlink functions 4. avoid wasteful/slow syscalls
2011-03-03	implement POSIX shared memory	Rich Felker	-0/+21
