2011-03-08disallow cpu time clocks as condattr clock valuesRich Felker-1/+1
2011-03-07fix off-by-one error in sem_(timed)wait (using old sem value instead of new)Rich Felker-1/+1
2011-03-07use the selected clock from the condattr for pthread_cond_timedwaitRich Felker-1/+2
2011-03-07implement pthread_rwlockattr_* (essentially no-ops)Rich Felker-0/+28
2011-03-07implement pthread_condattr_* interfacesRich Felker-0/+45
note that, while the attributes are stored, they are not used in pthread_cond_init yet.
2011-03-07reject invalid attribute settingsRich Felker-0/+2
note that this is a pedantic conformance issue and waste of code. it only affects broken code or code that is probing for conformance.
2011-03-07implement barrier attribute functions (essentially no-ops)Rich Felker-0/+27

2011-02-19use rt_sigprocmask, not legacy sigprocmask, syscall in pthread exit codeRich Felker-1/+1
2011-02-19race condition fix: block all signals before decrementing thread countRich Felker-22/+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.
2011-02-19make pthread_exit run dtors for last thread, wait to decrement thread countRich Felker-3/+3
2011-02-18add pthread_atfork interfaceRich Felker-0/+48
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.
2011-02-17reorganize pthread data structures and move the definitions to alltypes.hRich Felker-83/+83
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.
2011-02-16patch by njk, simplifies thread register initialization for x86_64Rich Felker-4/+0
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.
