Only catch SIGINFO (for dumping thread states) when LIBPTHREAD_DEBUG is defined in the environment. Modify the code path of the ifdef NOTYET part of _kse_single_thread(): o Don't reinitialise the atfork() handler list in the child. We are meant to call the child handler, and on subsequent fork()s should call all three functions as normal. o Don't reinitialise the thread specific keyed data in the child after a fork. Applications may require this for context. o Reinitialise curthread->tlflags after removing ourselves from (and reinitialising) the various internal thread lists. o Reinitialise __malloc_lock in the child after fork() (to balance our explicitly taking the lock prior to the fork()). With these changes, it is possible to enable the NOTYET code in thr_kern.c to allow the use of non-async-safe functions after fork()ing from a threaded program. Eliminate a race condition in timed waits (cv, mutex, and sleeps). Don't forget to initialize a tailq before using it. For the ``#ifdef NOTYET'' code that allows calling non-async-safe functions in the child after a fork() from a threaded process, use __sys_setprocmask() rather than setprocmask() to keep our signal handling sane. Without this fix, signals are essentially ignored in said child and things such as protection violations result in an endless busy loop. Allocate a thread's tcb last so it is easier to handle failures to malloc() siginfo. Include needed headers that were obtained through . Sort headers while here. amd64 ----- Fix a race condition introduced when redzones were added. Use an atomic operation to return and adjust the stack (amd64). test ----- o Include o Make this ILP32/LP64 clean: cast pointers to long. Approved by: re (scottl)

Clean out the leftovers from the i386_set_gsbase() TLS conversion.

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

Add a missing END() to quiet a warning.

Remove the special _amd64_set_gsbase() code for #ifdef COMPAT_32BIT, now

that the amd64 kernel implements i386_get/set_gsbase(). All the rest of the ldt backwards compat code should go away soon.

Use the i386_set_gsbase() syscall if it is implemented in the kernel.

This is a little hairy here because the allocation and usage of this functionality is split into two places in libpthread.

Use the new atomic_cmpset_32().

Bring in a more healthy version of the libpthread for arm, which uses

ARM_TP_ADDRESS.

i386_set_ldt() is not available when running 32 bit binaries on amd64

kernels. Use the recently exposed direct-set routines instead. This is only activated for when we compile i386 support libraries on amd64.
