Age	Commit message (Collapse)	Author	Files	Lines
2011-03-10	optimize pthread termination in the non-detached case	Rich Felker	1	-4/+15
	we can avoid blocking signals by simply using a flag to mark that the thread has exited and prevent it from getting counted in the rsyscall signal-pingpong. this restores the original pthread create/join throughput from before the sigprocmask call was added.
2011-03-10	security fix: check that cancel/rsyscall signal was sent by the process itself	Rich Felker	1	-0/+3

2011-02-19	use rt_sigprocmask, not legacy sigprocmask, syscall in pthread exit code	Rich Felker	1	-1/+1

2011-02-19	race condition fix: block all signals before decrementing thread count	Rich Felker	1	-0/+2
	the existence of a (kernelspace) thread must never have observable effects after the thread count is decremented. if signals are not blocked, it could end up handling the signal for rsyscall and contributing towards the count of threads which have changed ids, causing a thread to be missed. this could lead to one thread retaining unwanted privilege level. this change may also address other subtle race conditions in application code that uses signals.
2011-02-19	make pthread_exit run dtors for last thread, wait to decrement thread count	Rich Felker	1	-3/+3

2011-02-17	reorganize pthread data structures and move the definitions to alltypes.h	Rich Felker	1	-3/+3
	this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test.
2011-02-15	begin unifying clone/thread management interface in preparation for porting	Rich Felker	1	-4/+2

2011-02-15	make pthread_create return EAGAIN on resource failure, as required by POSIX	Rich Felker	1	-1/+1

2011-02-13	reorganize thread exit code, make pthread_exit call cancellation handlers (pt2)	Rich Felker	1	-13/+50

2011-02-12	initial check-in, version 0.5.0v0.5.0	Rich Felker	1	-0/+189
