This commit was manufactured to restore the state of the 5.5-RELEASE image.

This means .cerror has to be present in the same module with its consumers, or bad things will happen. Rethink the way thr_libc.So is generated.

OK'ed by: kan o Use a daemon thread to monitor signal events in kernel, if pending 2003-06-28T09:55:02Z David Xu davidxu@FreeBSD.org 2003-06-28T09:55:02Z urn:sha1:a772047bc659cf0fd4f41fb57895b1557ccb60c3 signals were changed in kernel, it will retrieve the pending set and try to find a thread to dispatch the signal. The dispatching process can be rolled back if the signal is no longer in kernel. o Create two functions _thr_signal_init() and _thr_signal_deinit(), all signal action settings are retrieved from kernel when threading mode is turned on, after a fork(), child process will reset them to user settings by calling _thr_signal_deinit(). when threading mode is not turned on, all signal operations are direct past to kernel. o When a thread generated a synchoronous signals and its context returned from completed list, UTS will retrieve the signal from its mailbox and try to deliver the signal to thread. o Context signal mask is now only used when delivering signals, thread's current signal mask is always the one in pthread structure. o Remove have_signals field in pthread structure, replace it with psf_valid in pthread_signal_frame. when psf_valid is true, in context switch time, thread will backout itself from some mutex/condition internal queues, then begin to process signals. when a thread is not at blocked state and running, check_pending indicates there are signals for the thread, after preempted and then resumed time, UTS will try to deliver signals to the thread. o At signal delivering time, not only pending signals in thread will be scanned, process's pending signals will be scanned too. o Change sigwait code a bit, remove field sigwait in pthread_wait_data, replace it with oldsigmask in pthread structure, when a thread calls sigwait(), its current signal mask is backuped to oldsigmask, and waitset is copied to its signal mask and when the thread gets a signal in the waitset range, its current signal mask is restored from oldsigmask, these are done in atomic fashion. o Two additional POSIX APIs are implemented, sigwaitinfo() and sigtimedwait(). o Signal code locking is better than previous, there is fewer race conditions. o Temporary disable most of code in _kse_single_thread as it is not safe after fork(). Provide a reference to __sys_write.

I may not really know what I'm talking about, but it works. Submitted by: kan Don't force -L/usr/lib.

This breaks building -CURRENT on 4.x as well.

Register libpthread-specific locking API with rtld on startup. This still has some rough edges with signals which should be addresses later. Approved by: re (scottl)
