heartbeat(9): Test whether curcpu is stable, not kpreempt_disabled. kpreempt_disabled worked for my testing because I tested on aarch64, which doesn't have kpreemption. XXX Should move curcpu_stable() to somewhere that other things can use it.

ASSERT_SLEEPABLE(9): Micro-optimize this a little bit. This convinces gcc to do less -- make a smaller stack frame, compute fewer conditional moves in favour of predicted-not-taken branches -- in the fast path where we are sleepable as the caller expects. Wasn't able to convince it to do the ncsw loop with a predicted-not-taken branch, but let's leave the __predict_false in there anyway because it's still a good prediction.

KERNEL_LOCK(9): Minor tweaks to ci->ci_biglock_wanted access. 1. Use atomic_load_relaxed to read ci->ci_biglock_wanted from another CPU, for clarity and to avoid the appearance of data races in thread sanitizers. (Reading ci->ci_biglock_wanted on the local CPU need not be atomic because no other CPU can be writing to it.) 2. Use atomic_store_relaxed to update ci->ci_biglock_wanted when we start to spin, to avoid the appearance of data races. 3. Add comments to explain what's going on and cross-reference the specific matching membars in mutex_vector_enter. related to PR kern/57240

Now we can detect violations of mutex restrictions on rump kernels such as taking an adaptive mutex with holding a spin mutex as well as normal kernels. -- rump: check if the mutex is surely owned by the caller in mutex_exit Unlocking a not-owned mutex wasn't detected well (it could detect if the mutex is not held by anyone but that's not enough). Let's check it (the check is the same as normal kernel's mutex). If LOCKDEBUG is enabled, give the check over LOCKDEBUG because it can provide better debugging information.

LOCKDEBUG: - Tweak it so it can also catch common errors with condition variables. The change to kern_condvar.c is not included in this commit and will come later. - Don't call kmem_alloc() if operating in interrupt context, just fail the allocation and disable debugging for the object. Makes it safe to do mutex_init/rw_init/cv_init in interrupt context, when running a LOCKDEBUG kernel.

Add MI code to support in-kernel preemption. Preemption is deferred by one of the following: - Holding kernel_lock (indicating that the code is not MT safe). - Bracketing critical sections with kpreempt_disable/kpreempt_enable. - Holding the interrupt priority level above IPL_NONE. Statistics on kernel preemption are reported via event counters, and where preemption is deferred for some reason, it's also reported via lockstat. The LWP priority at which preemption is triggered is tuneable via sysctl.

Merge scheduler changes from the vmlocking branch. All discussed on tech-kern: - Invert priority space so that zero is the lowest priority. Rearrange number and type of priority levels into bands. Add new bands like 'kernel real time'. - Ignore the priority level passed to tsleep. Compute priority for sleep dynamically. - For SCHED_4BSD, make priority adjustment per-LWP, not per-process.

- Fix interactivity problems under high load. Beacuse soft interrupts
are being stacked on top of regular LWPs, more often than not aston()
was being called on a soft interrupt thread instead of a user thread,
meaning that preemption was not happening on EOI.
- Don't use bool in a couple of data structures. Sub-word writes are not
always atomic and may clobber other fields in the containing word.
- For SCHED_4BSD, make p_estcpu per thread (l_estcpu). Rework how the
dynamic priority level is calculated - it's much better behaved now.
- Kill the l_usrpri/l_priority split now that priorities are no longer
directly assigned by tsleep(). There are three fields describing LWP
priority:
l_priority: Dynamic priority calculated by the scheduler.
This does not change for kernel/realtime threads,
and always stays within the correct band. Eg for
timeshared LWPs it never moves out of the user
priority range. This is basically what l_usrpri
was before.
l_inheritedprio: Lent to the LWP due to priority inheritance
(turnstiles).
l_kpriority: A boolean value set true the first time an LWP
sleeps within the kernel. This indicates that the LWP
should get a priority boost as compensation for blocking.
lwp_eprio() now does the equivalent of sched_kpri() if
the flag is set. The flag is cleared in userret().
- Keep track of scheduling class (OTHER, FIFO, RR) in struct lwp, and use
this to make decisions in a few places where we previously tested for a
kernel thread.
- Partially fix itimers and usr/sys/intr time accounting in the presence
of software interrupts.
- Use kthread_create() to create idle LWPs. Move priority definitions
from the various modules into sys/param.h.
- newlwp -> lwp_create

- Increase the number of thread priorities from 128 to 256. How the space is set up is to be revisited. - Implement soft interrupts as kernel threads. A generic implementation is provided, with hooks for fast-path MD code that can run the interrupt threads over the top of other threads executing in the kernel. - Split vnode::v_flag into three fields, depending on how the flag is locked (by the interlock, by the vnode lock, by the file system). - Miscellaneous locking fixes and improvements.

Pull up revision 1.81-1.83 via patch (requested by yamt in ticket #752): when acquiring an exclusive lock, ensure that no one else have the same lock. a patch from Stephan Uphoff, FreeBSD PR/69934. (http://www.freebsd.org/cgi/query-pr.cgi?pr=69934) Upgrading a lock does not play well together with acquiring an exclusive lock and can lead to two threads being granted exclusive access. Problematic sequence: Thread A acquires a previous unlocked lock in shared mode. Thread B tries to acquire the same lock in exclusive mode and blocks. Thread A upgrades its lock - waking up thread B. Thread B wakes up and also acquires the same lock as it only checks if the lock is not shared or if someone wants to upgrade the lock and not if someone already upgraded the lock to an exclusive lock. - revert a part of the previous which breaks LK_SPIN locks. (reported by Nicolas Joly on current-users@) - propagate the previous to spinlock_acquire_count. add missing wakeups in the cases of lock failure. from Stephan Uphoff, FreeBSD PR/69964.

Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
Snapshots may not be opened for writing and the attributes are read-only.
Use the mtime as the time this snapshot was taken.
Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
a vnode.
- Add snapshot support to ls, fsck_ffs and dump.
Welcome to 2.0F.

"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (*de*referencing curproc is another story, but that's always been true).

Default lock_printf to syslog rather than printf. Some of the lock debug checks are done inside of wakeup which is holding the sched lock. Printf can cause wakeup to get called again (pty redirection of console message) which will panic with sched lock already held. This isn't a long term fix as not being able to printf vs. sched lock should be cleaned up better but this avoids continual panics with lockdebug running and an xterm -C.

Some more lock debugging support: - LOCK_ASSERT(), which expands to KASSERT() if LOCKDEBUG. - new simple_lock_held(), which tests if the calling CPU holds the specified simple lock. From Bill Sommerfeld, modified slightly by me.

Pullup from trunk: It doesn't make sense to charge simple locks to proc's, because simple locks are held by CPUs. Remove p_simple_locks (which was unused anyway, really), and add a LOCKDEBUG check for held simple locks in mi_switch(). Grow p_locks to an int to take up the space previously used by p_simple_locks so that the proc structure doens't change size.

Fix assorted bugs around shutdown/reboot/panic time. - add a new global variable, doing_shutdown, which is nonzero if vfs_shutdown() or panic() have been called. - in panic, set RB_NOSYNC if doing_shutdown is already set on entry so we don't reenter vfs_shutdown if we panic'ed there. - in vfs_shutdown, don't use proc0's process for sys_sync unless curproc is NULL. - in lockmgr, attribute successful locks to proc0 if doing_shutdown && curproc==NULL, and panic if we can't get the lock right away; avoids the spurious lockmgr DIAGNOSTIC panic from the ddb reboot command. - in subr_pool, deal with curproc==NULL in the doing_shutdown case. - in mfs_strategy, bitbucket writes if doing_shutdown, so we don't wedge waiting for the mfs process. - in ltsleep, treat ((curproc == NULL) && doing_shutdown) like the panicstr case. Appears to fix: kern/9239, kern/10187, kern/9367. May also fix kern/10122.

Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files are also required to supply inline functions __cpu_simple_lock(), __cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be supported on that platform (i.e. if MULTIPROCESSOR is defined in the _KERNEL case). Change these functions to take an int * (&alp->lock_data) rather than the struct simplelock * itself. These changes make it possible for userland to use the locking primitives by including <machine/lock.h>.

Three MULTIPROCESSOR + LOCKDEBUG fixes: 1) fix typo preventing compilation (missing comma). 2) in SLOCK_WHERE, display cpu number in the MP case. 3) the folowing race condition was observed in _simple_lock: cpu 1 releases lock, cpu 0 grabs lock cpu 1 sees it's already locked. cpu 1 sees that lock_holder== "cpu 1" cpu 1 assumes that it already holds it and barfs. cpu 0 sets lock_holder == "cpu 0" Fix: set lock_holder to LK_NOCPU in _simple_unlock().

Improve the LOCKDEBUG code: - Now compatible with MULTIPROCESSOR (requires other changes not yet committed, but which will be later today). - In addition to tracking simple locks, track exclusive spin locks. - Count spin locks like we do sleep locks (in the cpu_info for this CPU). - Lock debug lists are now TAILQs, so as to make the locking order more obvious when dumping the list. Also, some suggestions from Bill Sommerfeld: - SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED constants, which may be defined in <machine/lock.h> (default to 1 and 0, respectively). This makes it easier to support architectures which use test-and-clear rather than test-and-set. - Add __attribute__((__aligned__)) to the `lock_data' member of the simplelock structure. This makes it easier to support architectures which can only perform atomic operations on very-well-aligned memory locations. NOTE: This changes the size of struct simplelock, and will cause a version bump.

Recursive locks were previously only available with LK_CANRECURSE. This could be done in one of 2 ways: * call lk_init with LK_CANRECURSE, resulting in a lock that always can be used recursively. * call lockmgr with LK_CANRECURSE, meaning that it's ok if this lock is already held by us. Sometimes we need a locking type that says: take this lock now, exclusively, but while I am holding it, I may go through a code path which could attempt to get the lock again, and which is unaware that the lock might already be taken. Implement LK_SETRECURSE for this purpose. Assume that locks and unlocks come in matching pairs (they should), and check for this 'level' using SETRECURSE locks.
