2013-08-31	fix missing return value warning in faccessat, minor cleanup	Rich Felker	1	-1/+1
	clone will pass the return value of the start function to SYS_exit anyway; there's no need to call the syscall directly.
2013-08-09	block all signals, even implementation-internal ones, in faccessat child	Rich Felker	1	-1/+1
	the child process's stack may be insufficient size to support a signal frame, and there is no reason these signal handlers should run in the child anyway.
2013-08-03	fix faccessat to support AT_EACCESS flag	Rich Felker	1	-1/+46
	this is another case of the kernel syscall failing to support flags where it needs to, leading to horrible workarounds in userspace. this time the workaround requires changing uid/gid, and that's not safe to do in the current process. in the worst case, kernel resource limits might prevent recovering the original values, and then there would be no way to safely return. so, use the safe but horribly inefficient alternative: forking. clone is used instead of fork to suppress signals from the child. fortunately this worst-case code is only needed when effective and real ids mismatch, which mainly happens in suid programs.
