2012-06-21	Update to reflect API changes	Philip Guenthe

2012-06-21	__tfork() needs to set the stack address of the new thread in the kernel,	Philip Guenthe
	so that it can't get a signal while still running on the parent thread's stack. Also, pass in sizeof(struct __tfork) to provide forward compat when more members are added. This is an ABI change, so switch syscall numbers and bump lib majors this time. ok deraadt@ matthew@
2012-05-06	Style nits from Brad.	Paul Irofti

2012-05-03	Add pthread spinlock support.	Paul Irofti
	Implementation, documentation and naive regression tests for: - pthread_spin_init() - pthread_spin_destroy() - pthread_spin_lock() - pthread_spin_trylock() - pthread_spin_unlock() Implementation okay guenther@, documentation okay jmc@.
2012-04-23	Honor subsystem style.	Paul Irofti
	`Visual inspection looks ok' kurt@. >From Brad
2012-04-17	Remove "#define _POSIX_THREADS" line before include <pthread.h>.	Miod Vallat
	The latter contains "#define _POSIX_THREADS 1" which makes gcc 2.95 complain.
2012-04-14	Add new mutex type, PTHREAD_MUTEX_STRICT_NP which checks for application	Kurt Miller
	errors similar to PTHREAD_MUTEX_ERRORCHECK, however upon error it aborts. The rational is that many applications don't check the return values on pthread functions and will miss the errors that ERRORCHECK returns. PTHREAD_MUTEX_STRICT_NP will be our default mutex type for awhile okay guenther@ dcoppa@
2012-04-13	Provide _atomic_lock() and __cerror() for hppa64. Makes hppa64 build again.	Joel Sing

2012-04-13	Use PTHREAD_MUTEX_DEFAULT in static init and mutexattr_init. If the	Kurt Miller
	default mutex type changes to NORMAL, when there is an uninitialized mutex provided to unlock, allow it to succeed similar to an unlocked mutex. For other cases abort instead of segfault. okay guenther@
2012-04-13	Per POSIX, PTHREAD_MUTEX_NORMAL type mutexes have undefined behavior for	Kurt Miller
	certain conditions. In the case of unlocking an unlocked mutex we will allow that to succeed, all other undefined behaviors will result in an immediate abort(). okay guenther@
2012-04-13	Add sigwaitinfo and sigtimedwait stubs under #if 0; a bit more kernel	Philip Guenthe
	support is needed before they can be usefully enabled but I don't want to misplace this diff yet again
2012-04-12	remove rfork(); ok guenther miod	Theo de Raadt

2012-04-11	Minor bump after my previous commit. Noticed by deraadt@.	Paul Irofti

2012-04-11	Add pthread barrier support.	Paul Irofti
	Implementation and documentation for: - pthread_barrier_init() - pthread_barrier_destroy() - pthread_barrier_wait() - pthread_barrierattr_init() - pthread_barrierattr_destroy() - pthread_barrierattr_getpshared() - pthread_barrierattr_setpshared() Currently only private barriers are supported. Okay guenther@.
2012-04-10	pthread_setcanceltype() shouldn't be a cancelation point	Philip Guenthe
	ok kurt@
2012-04-06	Fix typo.	Joel Sing

2012-03-22	Remove pthread_suspend* and related functions. This is part of the	Kurt Miller
	rthreads major library bump from last night. okay kettenis@
2012-03-22	bump majors on libc and rthreads for the additions to libc and transfer	Philip Guenthe
	of __tfork_thread from rthreads to libc
2012-03-22	closefrom() should be a cancellation point	Philip Guenthe

2012-03-22	tfork_thread has been moved to libc	Philip Guenthe

2012-03-22	Move __tfork_thread() from rthreads (libpthread) to libc so that	Philip Guenthe
	it can be used for not-strictly-threading purposes ok matthew@ kurt@
2012-03-20	Clean up unnecessary prototypes. Pointed out by brad@	Philip Guenthe

2012-03-20	Permit recursive locking in _rthread_dl_lock(), as an so's destructor	Philip Guenthe
	may need to call dlclose(). problem observed by Antti Harri (iku at openbsd.fi), ok kurt@
2012-03-14	Force sched_yield() to be resolved before calling dlctl(DL_SET*LCK) with	Philip Guenthe
	a function that can call sched_yield(), to avoid recursion ok kurt@ kettenis@
2012-03-13	Don't trust the environment if issetugid()	Philip Guenthe

2012-03-03	Sync the assembly statements with <machine/lock.h> for consistency.	Miod Vallat

2012-03-03	Bump minor for recent additions	Philip Guenthe

2012-03-03	sem_timedwait() should return ETIMEDOUT instead of EWOULDBLOCK on timeout	Philip Guenthe

2012-03-03	Add sem_timewait() and fix sem_wait()'s handling of signals, so	Philip Guenthe
	that it resumes waiting unless the thread was canceled. As part of this, change the internal _sem_wait() function to return zero on success and an errno value on failure instead of 1 on success and zero on failure.
2012-03-02	fix check when setting the contention scope. harmless atm but still wrong.	Federico G. Schwindt
	guenther@ ok.
2012-03-02	for readability, put the label on it's own line.	Federico G. Schwindt

2012-03-02	_SPINLOCK_UNLOCKED isn't zero everywhere (coughhppacough), so	Philip Guenthe
	sem_init() can't assume that calloc will leave the embedded spinlock in the unlocked state ok miod@ otto@
2012-02-28	Our default mutex type is PTHREAD_MUTEX_ERRORCHECK, for which trying	Philip Guenthe
	to unlock an uninitialized mutex is required to return EPERM, so add the necessary checks. For recursive mutexes, return an error from pthread_mutex_lock() if the count would overflow. problem observed in glib testing by aja@
2012-02-27	fix __errno symbol name	Miod Vallat

2012-02-26	Fix buglets.	Miod Vallat

2012-02-26	__cerror gets invoked with errno in v0, not a0.	Miod Vallat

2012-02-26	Fix label for threaded binaries to link.	Miod Vallat

2012-02-24	sched_yield() is the standard name while pthread_yield() is the	Philip Guenthe
	non-standard alias, so prefer the former
2012-02-23	PTHREAD_MUTEX_NORMAL mutexes are supposed to self-deadlock, not abort.	Philip Guenthe
	That deadlock can be exited via a timeout for pthread_mutex_timedlock(). Unwind all the state when pthread_mutex_timedlock() times out
2012-02-23	Add pthread_condattr_{get,set}clock(), requested by aja@	Philip Guenthe
	Add pthread_mutex_timedlock(), requested by dcoppa@
2012-02-21	Make pthread_suspend_np() and pthread_resume_np() simply fail instead	Philip Guenthe
	of doing the Wrong Thing.
2012-02-19	Fix problems revealed by regress/lib/libpthread/stack/stack.c	Philip Guenthe

2012-02-19	Use 'base' as an intermediate char* variable to avoid void* arithmetic	Philip Guenthe

2012-02-19	Extend miod's fix CFLAGS fix to all gcc2 platforms (suggested by Tobias	Philip Guenthe
	Ulmer). Only pull in bsd.lib.mk once to avoid linking objects twice
2012-02-19	Use a form of designated initializer that works with gcc2	Philip Guenthe
	lint doesn't understand designated initializers, so hide them from it
2012-02-19	Validate in pthread_attr_set{scope,sched{param,policy},inheritsched}()	Philip Guenthe
	the requested new value
2012-02-18	Fix previous commit: _rthread_init() was static.	Philip Guenthe
	Improve consistency of error naming
2012-02-18	Before using _thread_pagesize, make sure _rthread_init() has been called	Philip Guenthe

2012-02-18	id tag.	Federico G. Schwindt

2012-02-18	Fix the handling of the stackaddr, stacksize, and guardsize attributes:	Philip Guenthe
	don't try to merge values, round the sizes separately, and don't try to unmap application-supplied stacks. Copy from uthread the caching of default-sized stacks. Have pthread_attr_init() and pthread_create() get the default attributes from staticly allocated pthread_attr_t. Cache the pagesize in _rthread_init() and provide a macro for rounding to it based on suggestions from kettenis@ and tedu@, ok kettenis@
