* Begin making libthr async signal safe.Mike Makonnen2003-07-021-2/+22
| | | | | | | | | | | Create a private, single underscore, version of pthread_mutex_unlock for libc. pthread_mutex_lock already has one. These versions are different from the ones that applications will link against because they block all signals from the time a call to lock the mutex is made until it is successfully unlocked.

* Add a new mount flag MNT_BYFSID that can be used to unmount a fileIan Dowse2003-07-011-1/+17
| | | | | | | | | | | | | | | | | | | | | system by specifying the file system ID instead of a path. Use this by default in umount(8). This avoids the need to perform any vnode operations to look up the mount point, so it makes it possible to unmount a file system whose root vnode cannot be looked up (e.g. due to a dead NFS server, or a file system that has become detached from the hierarchy because an underlying file system was unmounted). It also provides an unambiguous way to specify which file system is to be unmunted. Since the ability to unmount using a path name is retained only for compatibility, that case now just uses a simple string comparison of the supplied path against f_mntonname of each mounted file system. Discussed on: freebsd-arch mdoc help from: ru Notes: svn path=/head/; revision=117132
* Do not attempt to reque a thread on a mutex queue. It may be thatMike Makonnen2003-07-011-1/+1
| | | | | | | | | | | | a thread receives a spurious wakeup from sigtimedwait(), so make sure that the call to the queueing code is called only once before entering the loop (not in the loop). This should fix some fatal errors people are seeing with messages stating the thread is already on the mutex queue. These errors may still be triggered from signal handlers; however, since that part of the code is not locked down yet. Notes: svn path=/head/; revision=117127

| | | | | | | | | | | The old buffer was not being initialized and a later str*() op on it would cause a crash if it wasn't initialized by a previous call to setproctitle(3) with an actual string. Noticed by: Ashley Penney <ashp@unloved.org> Notes: svn path=/head/; revision=117102
* Separate the description of the flags for mount(2) and unmount(2)Ian Dowse2003-06-301-14/+16
| | | | | | | | | | | to clarify which system call accepts which arguments. Previously the manual page gave the impression that calling unmount() with flags of (MNT_FORCE | MNT_UPDATE | MNT_RDONLY) would downgrade a read-write mount to read-only, which is clearly untrue; to do that, these flags should be passed to mount() instead.

* Locking primitives and operations in libthr should use struct umtx,Mike Makonnen2003-06-292-4/+22
| | | | | | | | | | | | | | not spinlock_t. Spinlock_t and the associated functions and macros may require blocking signals in order for async-safe libc functions to behave appropriately in libthr. This is undesriable for libthr internal locking. So, this is the first step in completely separating libthr from libc's locking primitives. Three new macros should be used for internal libthr locking from now on: THR_LOCK, THR_TRYLOCK, THR_UNLOCK. Notes: svn path=/head/; revision=117048
* In a critical section, separate the aquisition of the thread lockMike Makonnen2003-06-292-17/+27
| | | | | | | | | | | | | | | and the disabling of signals. What we are really interested in is keeping track of recursive disabling of signals. We should not be recursively acquiring thread locks. Any such situations should be reorganized to not require a recursive lock. Separating the two out also allows us to block signals independent of acquiring thread locks. This will be needed in libthr in the near future when we put the pieces together to protect libc functions that use pthread mutexes and low level locks. Notes: svn path=/head/; revision=117046
* Add a libc function execvP that takes the search path as an arguement.Gordon Tetlow2003-06-292-15/+40

* Make _thread_suspend work with both the old broken sigtimedwaitJohn Polstra2003-06-293-11/+31

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().
