Author	SHA1	Message	Date
Rich Felker	52213f7341	security fix: check that cancel/rsyscall signal was sent by the process itself	15 years ago
Rich Felker	500c969f05	fix error handling for pthread_sigmask it must return errno, not -1, and should reject invalud values for how.	15 years ago
Rich Felker	6dc05fbe19	optimize pthread initialization the set_tid_address returns the tid (which is also the pid when called from the initial thread) so there is no need to make a separate syscall to get pid/tid.	15 years ago
Rich Felker	31e06075d5	simplify and optimize pthread_mutex_trylock	15 years ago
Rich Felker	e5dd18319b	rwlock trylock functions were wrongly returning EAGAIN instead of EBUSY	15 years ago
Rich Felker	7e6be42a77	fix major breakage in pthread_once (it was always deadlocking) the issue was a break statement that was breaking only from the switch, not the enclosing for loop, and a failure to set the final success state.	15 years ago
Rich Felker	4820f9268d	fix and optimize non-default-type mutex behavior problem 1: mutex type from the attribute was being ignored by pthread_mutex_init, so recursive/errorchecking mutexes were never being used at all. problem 2: ownership of recursive mutexes was not being enforced at unlock time.	15 years ago
Rich Felker	1d6b1f1592	implement pthread_mutexattr_[gs]etpshared functions	15 years ago
Rich Felker	9d5251f72b	disallow cpu time clocks as condattr clock values	15 years ago
Rich Felker	9fe28f703d	fix off-by-one error in sem_(timed)wait (using old sem value instead of new)	15 years ago
Rich Felker	5fd4a98165	use the selected clock from the condattr for pthread_cond_timedwait	15 years ago
Rich Felker	cc2e0b45a6	implement pthread_rwlockattr_* (essentially no-ops)	15 years ago
Rich Felker	b4d40e44e3	implement pthread_condattr_* interfaces note that, while the attributes are stored, they are not used in pthread_cond_init yet.	15 years ago
Rich Felker	63b06c0e90	reject invalid attribute settings note that this is a pedantic conformance issue and waste of code. it only affects broken code or code that is probing for conformance.	15 years ago
Rich Felker	951e764091	implement barrier attribute functions (essentially no-ops)	15 years ago
Rich Felker	8c967b9386	enforce stack size min in pthread_attr_setstacksize	15 years ago
Rich Felker	6fc5fdbdc7	implement POSIX semaphores	15 years ago
Rich Felker	b480808a6a	optimize POSIX TSD for fast pthread_getspecific	15 years ago
Rich Felker	98e02144da	use rt_sigprocmask, not legacy sigprocmask, syscall in pthread exit code	15 years ago
Rich Felker	19eb13b9a4	race condition fix: block all signals before decrementing thread count 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.	15 years ago
Rich Felker	fb11b6b85e	make pthread_exit run dtors for last thread, wait to decrement thread count	15 years ago
Rich Felker	e9417fffb3	add pthread_atfork interface note that this presently does not handle consistency of the libc's own global state during forking. as per POSIX 2008, if the parent process was threaded, the child process may only call async-signal-safe functions until one of the exec-family functions is called, so the current behavior is believed to be conformant even if non-ideal. it may be improved at some later time.	15 years ago
Rich Felker	e882756311	reorganize pthread data structures and move the definitions to alltypes.h 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.	15 years ago
Rich Felker	e3657ba599	patch by njk, simplifies thread register initialization for x86_64 It's not necessary to save any registers on the stack across syscall in x86_64 __set_thread_area. Don't waste cycles or bytes on it.	15 years ago
Rich Felker	22cd9cae81	patch from njk: make x86_64 __uniclone branchless.	15 years ago
Nicholas J. Kain	1e12632591	Port musl to x86-64. One giant commit!	15 years ago
Rich Felker	7b2dd2235d	finish unifying thread register handling in preparation for porting	15 years ago
Rich Felker	0b2006c8fe	begin unifying clone/thread management interface in preparation for porting	15 years ago
Rich Felker	59666802fb	make pthread_create return EAGAIN on resource failure, as required by POSIX	15 years ago
Rich Felker	1a9a2ff7b0	reorganize thread exit code, make pthread_exit call cancellation handlers (pt2)	15 years ago
Rich Felker	50e26f09eb	reorganize thread exit code, make pthread_exit call cancellation handlers	15 years ago
Rich Felker	0b44a0315b	initial check-in, version 0.5.0	15 years ago
