Use a generic way to back threads out of wait queues when handling

2004-12-18T18:07:37+00:00

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()).

In collaboration with:	davidxu

Add a wrapper for execve(). The exec'd process must be started with

2004-09-26T06:50:15+00:00

the signal mask and pending signals of the calling thread.  These
are stored in userland in libpthread.

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.

Implement sigaltstack() as per-threaded. Current only scope process thread

is supported, for scope system process, kernel signal bits need to be
changed.

Add an implementation for pthread_atfork().

Aside from the POSIX requirements for pthread_atfork(), when
fork()ing, take the malloc lock to keep malloc state consistent
in the child.
