* Clean out the leftovers from the i386_set_gsbase() TLS conversion.Peter Wemm2005-06-292-51/+8
| | | | | | | | | | | Like on libthr, there is an i386_set_gsbase() stub implementation here to avoid libc.so.5 issues. This should likely be a weak symbol and I expect this will be fixed soon. Approved by: re Notes: svn path=/head/; revision=147673

* Use a generic way to back threads out of wait queues when handlingDaniel Eischen2004-12-1817-347/+412
| | | | | | | | | | | | | | | | | | | | | | | | | | | | signals instead of having more intricate knowledge of thread state within signal handling. Simplify signal code because of above (by David Xu). Use macros for libpthread usage of pthread_cleanup_push() and pthread_cleanup_pop(). This removes some instances of malloc() and free() from the semaphore and pthread_once() implementations. When single threaded and forking(), make sure that the current thread's signal mask is inherited by the forked thread. Use private mutexes for libc and libpthread. Signals are deferred while threads hold private mutexes. This fix also breaks www/linuxpluginwrapper; a patch that fixes it is at http://people.freebsd.org/~deischen/kse/linuxpluginwrapper.diff Fix race condition in condition variables where handling a signal (pthread_kill() or kill()) may not see a wakeup (pthread_cond_signal() or pthread_cond_broadcast()).

There is a small race condition in this patch which could cause problems if a signal arrives after setting the (kernel) signal mask and before exec'ing. The thread's set of pending signals also are not yet installed in the exec'd process. Both of these will be corrected with the addition of a special syscall.
