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

| * | make pthread_exit run dtors for last thread, wait to decrement thread count | Rich Felker | 2011-02-19 | 1 | -3/+3 |
| * | 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.

| * | 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.

| * | 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.
