| | | | | 64bit archs to accommodate the growing number of ports that put large buffers on the stack. Supported by many with no objections.

* Application-specified thread stacks didn't work with libpthreadguenther2008-07-071-11/+7
| | | | | | | because it treated the supplied memory as holding an internal data structure instead of as the stack space itself ok kurt@, "looks ok" otto@, tested on hppa by kettenis@

* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-261-8/+1
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@
* Move _POSIX_THREAD_SAFE_FUNCTIONS into unistd.h and set it to 200112millert2008-06-251-2/+1
| | | | | now that we support all the _r functions required by POSIX 1003.1-2001. Also define _POSIX_REENTRANT_FUNCTIONS. OK kurt@ deraadt@

* Don't grab the fd read lock for getsockopt(2), setsockopt(2),kurt2008-06-034-18/+66
| | | | | | | | getpeername(2) or getsockname(2). Its not needed and causes threads to block when another thread is blocked and holding the read lock. Instead just protect against fd state transitions. Blocking problem reported by David S H Rosenthal from lockss.org okay beck@ "looks sane" deraadt@
* Return the proper values upon failure per POSIX for pthread_sigmask(3) andkurt2008-04-242-5/+12
| | | | | | | sigprocmask(2) in threaded programs. From Philip Guenther <guenther at sendmail.com> via PR library/5795. okay marc@
* - do not call pthread_atfork(3) handlers when a multithreaded programkurt2008-04-042-27/+49
| | | | | | calls vfork(2). "untested, but looks OK" marc@ - document vfork(2), popen(3) and system(3) don't call atfork handlers in multithreaded programs. okay jmc@

* - make arc4random*() functions thread safe. Use a custom spinlock functionkurt2008-01-013-3/+18
| | | | | | | | | | | instead of the generic pthread macros since free(3) uses __arc4_getbyte() when freeing small sized allocations and the generic pthread macros call malloc(3). - eliminate passing pointers to a static variable with global scope (rs) for additional code clarity and reduction. - shlib minor bumps for libc and libpthread due to new functions. From andreas@ with some bits from me. okay tedu@ marc@ w/some spot checking from millert@
* make pthread vfork() not call fork(), but actually call vfork(). ourderaadt2007-11-203-6/+17
| | | | | | | vfork() has only one semantic: "parent stalls until child does execve or exit" and no other semantic. it is unfair to act as if pthread vfork() suddenly lacks that semantic. ok kurt millert kettenis beck

| | | | | | | | by replicating part of $$dyncall in the code that sets up a thread's initial stack frame. Also make sure we actually reserve some space for that initial stack frame. ok miod@
* _FD_LOCK/UNLOCK() is libpthread specific and not needed for librthread, sokurt2007-06-059-12/+190
| | | | | | | | | | | | | | | | | | | | | | | | | | isolate its usage to libpthread only and replace with generic non-static mutex support in the one place it is needed: - remove _FD_LOCK/UNLOCK from lseek and ftruncate in libc and make the functions weak so that libpthread can override with its own new versions that do the locking. - remove _thread_fd_lock/unlock() weak functions from libc and adjust libpthread for the change. - add generic _thread_mutex_lock/unlock/destroy() weak functions in libc to support non-static mutexes in libc and add libpthread and librthread implementations for them. libc can utilize non-static mutexes via the new _MUTEX_LOCK/UNLOCK/DESTROY() macros. Actually these new macros can support both static and non-static mutexes but currently only using them for non-static. - make opendir/closedir/readdir/readdir_r/seekdir/telldir() thread-safe for both thread libraries by using a non-static mutex in the struct _dirdesc (typedef DIR), utilizing it in the *dir functions and remove remaining and incorrect _FD_LOCK/UNLOCK() use in libc. - add comments to both thread libraries to indicate libc depends on the current implementation of static mutex initialization. suggested by marc@ - major bump libc and libpthread due to function removal, structure change and weak symbol conversions. okay marc@, tedu@

| | | | | | | | from the parent to all non-blocking. This prevents the child from restoring the file to be blocking upon close() and causing the parent to deadlock when it later attempts to utilize the blocking fd. Corrects the netbeans build failure caused by the jdk forkAndExec() function that replaces the std fd's before execvp(). okay marc@
