Adjust KERNEL_ASSERT_UNLOCKED() to not assert during a panic.

KERNEL_ASSERT_UNLOCKED calls _kernel_lock_held() which returns true
if panicstr || db_active which triggers this assert. Workaround this by
checking them before.

clockintr: move callback-specific API behaviors to "clockrequest" namespace

The API's behavior when invoked from a callback function is impossible
to document.  Move the special behavior into a distinct namespace,
"clockrequest".

- Add a 'struct clockrequest'.  Basically a stripped-down 'struct clockintr'
  for exclusive use during clockintr_dispatch().
- In clockintr_queue, replace the "cq_shadow" clockintr with a "cq_request"
  clockrequest.  They serve the same purpose.
- CLST_SHADOW_PENDING -> CR_RESCHEDULE; different namespace, same meaning.
- CLST_IGNORE_SHADOW -> CLST_IGNORE_REQUEST; same meaning.
- Move shadow branch in clockintr_advance() to clockrequest_advance().
- clockintr_request_random() becomes clockrequest_advance_random().
- Delete dead shadow branches in clockintr_cancel(), clockintr_schedule().
- Callback functions now get a clockrequest pointer instead of a special
  clockintr pointer: update all prototypes, callers.

No functional change intended.

kernel: expand fixed clock interrupt periods to 64-bit values

Technically, all the current fixed clock interrupt periods fit within
an unsigned 32-bit value.  But 32-bit multiplication is an accident
waiting to happen.  So, expand the fixed periods for hardclock,
statclock, profclock, and roundrobin to 64-bit values.

One exception: statclock_mask remains 32-bit because random(9) yields
32-bit values.  Update the initclocks() comment to make it clear that
this is not an accident.

clockintr, statclock: eliminate clockintr_statclock() wrapper

- Move remaining statclock variables from kern_clockintr.c to
  kern_clock.c.  Move statclock variable initialization from
  clockintr_init() into initclocks().

- Change statclock() prototype to make it a legal clockintr
  callback function and establish the handle with statclock()
  instead clockintr_statclock().

- Merge the contents of clockintr_statclock() into statclock().
  statclock() can now reschedule itself and handles multiple
  expirations transparently.

- Make statclock_avg visible from sys/systm.h so that clockintr_cpu_init()
  can use it to advance the statclock across suspend/hibernate.

clockintr: replace CL_RNDSTAT with global variable statclock_is_randomized

In order to separate the statclock from the clock interrupt subsystem
we need to move all statclock state out into the broader kernel.

Start by replacing the CL_RNDSTAT flag with a new global variable,
"statclock_is_randomized", in kern_clock.c.  Update all clockintr_init()
callers to set the boolean instead of passing the flag.

all platforms: separate cpu_initclocks() from cpu_startclock()

To give the primary CPU an opportunity to perform clock interrupt
preparation in a machine-independent manner we need to separate the
"initialization" parts of cpu_initclocks() from the "start the clock
interrupt" parts.  Currently, cpu_initclocks() does everything all at
once, so there is no space for this MI setup.

Many platforms have more-or-less already done this separation by
implementing a separate routine named "cpu_startclock()".  This patch
promotes cpu_startclock() from de facto standard to mandatory API.

- Prototype cpu_startclock() in sys/systm.h alongside cpu_initclocks().
  The separation of responsibility between the two routines is a bit
  fuzzy but the basic guidelines are as follows:

  + cpu_initclocks() must initialize hz, stathz, and profhz, and call
    clockintr_init().

  + cpu_startclock() must call clockintr_cpu_init() and start the clock
    interrupt cycle on the calling CPU.

  These guidelines will shift in the future, but that's the way things
  stand as of *this* commit.

- In initclocks(): first call cpu_initclocks(), then do MI setup, and
  last call cpu_startclock().

- On platforms where cpu_startclock() already exists: don't call
  cpu_startclock() from cpu_initclocks() anymore.

- On platforms where cpu_startclock() doesn't yet exist: implement it.
  Usually this is as simple as dividing cpu_initclocks() in two.

hardclock(9): move setitimer(2) code into itimer_update()

- Move the setitimer(2) code responsible for updating the ITIMER_VIRTUAL
  and ITIMER_PROF timers from hardclock(9) into a new clock interrupt
  routine, itimer_update().  itimer_update() is periodic and runs at the
  same frequency as the hardclock.

  + Revise itimerdecr() to run within itimer_mtx instead of entering
    and leaving it.

- Each schedstate_percpu has its own itimer_update() handle, spc_itimer.
  A new scheduler flag, SPCF_ITIMER, indicates whether spc_itimer was
  started during the last mi_switch() and needs to be stopped during the
  next mi_switch() or sched_exit().

- A new per-process flag, PS_ITIMER, indicates whether ITIMER_VIRTUAL
  and/or ITIMER_PROF are running.  Checking the flag is easier than
  entering itimer_mtx to check process.ps_timer[].  The flag is set
  and cleared in a new helper function, process_reset_itimer_flag().

- In setitimer(), call need_resched() when the state of ITIMER_VIRTUAL
  or ITIMER_PROF is changed to force an mi_switch() and update
  spc_itimer.

claudio@ notes that ITIMER_PROF could be implemented as a high-res
timer using the thread's execution time as a guide for when to
interrupt the process and assert SIGPROF.  This would probably work
really well in single-threaded processes.  ITIMER_VIRTUAL would be
more difficult to make high-res, though, as you need to exclude time
spent in the kernel.

Tested on powerpc64 by gkoehler@.  With input from claudio@.

First step at removing struct sleep_state.

Pass the timeout and sleep priority not only to sleep_setup() but also
to sleep_finish(). With that sls_timeout and sls_catch can be removed
from struct sleep_state.

The timeout is now setup first thing in sleep_finish() and no longer as
last thing in sleep_setup(). This should not cause a noticeable difference
since the code run between sleep_setup() and sleep_finish() is minimal.

On systems without xonly mmu hardware-enforcement, we can still mitigate
against classic BROP with a range-checking wrapper in front of copyin() and
copyinstr() which ensures the userland source doesn't overlap the main program
text, ld.so text, signal tramp text (it's mapping is hard to distinguish
so it comes along for the ride), or libc.so text.  ld.so tells the kernel
libc.so text range with msyscall(2).  The range checking for 2-4 elements is
done without locking (because all 4 ranges are immutable!) and is inexpensive.

write(sock, &open, 400) now fails with EFAULT.  No programs have been
discovered which require reading their own text segments with a system call.

On a machine without mmu enforcement, a test program reports the following:

kernel: introduce per-CPU panic(9) message buffers

Add a 512-byte buffer (ci_panicbuf) to each cpu_info struct on each
platform for use by panic(9).  The first panic on a given CPU writes
its message to this buffer.  Subsequent panics on a given CPU print
the panic message to the console but do not modify the buffer.  This
aids debugging in two cases:

- If 2+ CPUs panic simultaneously there is no risk of garbled messages
  in the panic buffer.

- If a CPU panics and then the operator causes a second panic while
  using ddb(4), the operator can still recall the first failure on
  a particular CPU.

Misc. changes to support this bigger change:

- Set panicstr atomically to identify the first CPU to reach panic().

- Tweak db_show_panic_cmd() to print all panic messages across all
  CPUs.  Prefix the first panic with an asterisk ('*').

- Prefer db_printf() to printf() during a panic if we have it.
  Apparently it disturbs less global state.

- On amd64, tweak fault() to write the local panic buffer.  This needs
  more work.

tsleep(9): add global "nowake" channel for threads avoiding wakeup(9)

It would be convenient if there were a channel a thread could sleep on
to indicate they do not want any wakeup(9) broadcasts.  The easiest way
to do this is to add an "int nowake" to kern_synch.c and extern it in
sys/systm.h.  You use it like this:

	#include <sys/systm.h>

	tsleep_nsec(&nowait, ...);

There is now no need to handroll a local dead channel, e.g.

	int chan;

	tsleep_nsec(&chan, ...);

which expands the stack.  Local dead channels will be replaced with
&nowake in later patches.

One possible problem with this "one global channel" approach is sleep
queue congestion.  If you have lots of threads sleeping on &nowake you
might slow down a wakeup(9) on a different channel that hashes into
the same queue.  Unsure how much of problem this actually is, if at all.

NetBSD and FreeBSD have a "pause" interface in the kernel that chooses
a suitable channel automatically.  To keep things simple and avoid
adding a new interface we will start with this global channel.

Discussed with mpi@, claudio@, kettenis@, and deraadt@.

Basically designed by kettenis@, who vetoed my other proposals.

Bugs caught by deraadt@, tb@, and patrick@.

tsleep_nsec(9): add MAXTSLP macro, the maximum sleep duration

This macro will be useful for truncating durations below INFSLP
(UINT64_MAX) when converting from a timespec or timeval to a count
of nanoseconds before calling tsleep_nsec(9), msleep_nsec(9), or
rwsleep_nsec(9).

A relative timespec can hold many more nanoseconds than a uint64_t
can.  TIMESPEC_TO_NSEC() and TIMEVAL_TO_NSEC() check for overflow,
returning UINT64_MAX if the conversion would overflow a uint64_t.

Thus, MAXTSLP will make it easy to avoid inadvertently passing INFSLP
to tsleep_nsec(9) et al. when the caller intended to set a timeout.

The code in such a case might look something like this:

	uint64_t nsecs = MIN(TIMESPEC_TO_NSEC(&ts), MAXTSLP);

The macro may also be useful for rejecting intervals that are "too large",
e.g. for sockets with timeouts, if the timeout duration is to be stored
as a uint64_t in an object in the kernel.  The code in such a case might
look something like this:

	case SIOCTIMEOUT:
	{
		struct timeval *tv = (struct timeval *)data;
		uint64_t nsecs;

		if (tv->tv_sec < 0 || !timerisvalid(tv))
			return EINVAL;

		nsecs = TIMEVAL_TO_NSEC(tv);
		if (nsecs > MAXTSLP)
			return EOVERFLOW;

		obj.timeout = nsecs;
		break;
	}

Idea suggested by visa@.

softclock: move softintr registration/scheduling into timeout module

softclock() is scheduled from hardclock(9) because long ago callouts were
processed from hardclock(9) directly.  The introduction of timeout(9) circa
2000 moved all callout processing into a dedicated module, but the softclock
scheduling stayed behind in hardclock(9).

We can move all the softclock() "stuff" into the timeout module to make
kern_clock.c a bit cleaner.  Neither initclocks() nor hardclock(9) need
to "know" about softclock().  The initial softclock() softintr registration
can be done from timeout_proc_init() and softclock() can be scheduled
from timeout_hardclock_update().

Add tsleep_nsec(9), msleep_nsec(9), and rwsleep_nsec(9).

Equivalent to their unsuffixed counterparts except that (a) they take
a timeout in terms of nanoseconds, and (b) INFSLP, aka UINT64_MAX (not
zero) indicates that a timeout should not be set.

For now, zero nanoseconds is not a strictly valid invocation: we log a
warning on DIAGNOSTIC kernels if we see such a call.  We still sleep
until the next tick in such a case, however.  In the future this could
become some sort of poll... TBD.

To facilitate conversions to these interfaces: add inline conversion
functions to sys/time.h for turning your timeout into nanoseconds.

Also do a few easy conversions for warmup and to demonstrate how
further conversions should be done.

Lots of input from mpi@ and ratchov@.  Additional input from tedu@,

Remove file name and line number output from witness(4)

Reduce code clutter by removing the file name and line number output
from witness(4). Typically it is easy enough to locate offending locks
using the stack traces that are shown in lock order conflict reports.
Tricky cases can be tracked using sysctl kern.witness.locktrace=1 .

Do not panic from ddb(4) when a lock requirement isn't fulfilled.

Extend the logic already present for panic() to any DDB-related
operation such that if ddb(4) is entered because of a fault or
other trap it is still possible to call 'boot reboot'.

While here stop printing splassert() messages as well, to not fill

to syslog(3) something.  With the backout also dmesg -s works again.

If sendsyslog(2) is called with LOG_CONS before syslogd(8) has been

crash as the console device has not been initialized.  Open
/dev/console in the kernel before starting init(8) and keep it open.
This way sendsyslog(2) can be called early in the system.

KERNEL_ASSERT_LOCKED(9): Assertion for kernel lock (Rev. 3)

This adds a new assertion macro, KERNEL_ASSERT_LOCKED(), to assert that
kernel_lock is held.  In the long process of removing kernel_lock, there will
be a lot (hundreds or thousands) of use of this; virtually almost all functions
in !MP-safe subsystems should have this assertion.  Thus this assertion should
have a short, good name.

Not only that "KERNEL_ASSERT_LOCKED" is consistent with other KERNEL_* and
SCHED_ASSERT_LOCKED() macros.

Add possibility to add flags to syscalls in syscalls.master to mark
syscalls as NOLOCK and MPSAFE. The flags have slightly different semantics:
 NOLOCK - the syscall doesn't grab any locks whatsoever.
 MPSAFE - the syscall deals with its own locking.

What this means in practice is that NOLOCK syscalls can always be done
without the biglock. The MPSAFE syscalls can be done without the biglock
on CPUs that don't handle interrupts that require biglock (to preserve
lock ordering).

- Add a flags argument to dohooks.

   o HOOK_REMOVE removes the hook from the list before executing it.
   o HOOK_FREE frees the hook after that.

- Let dostartuphooks use HOOK_REMOVE|HOOK_FREE so we can reclaim the memory.

- Let doshutdownhooks use HOOK_REMOVE so that when some shutdown hook
  panics (they do that all the #@$%! time these days) we don't loop
  for ever. Don't HOOK_FREE, it doesn't matter and I don't want to add
  another possible panic condition for shutdown hooks.

- Actually free the pointer we're throwing away in hook_disestablish (I wonder
  how much memory this has leaked over the years).

XXX Will go away when Jason's kevents come to life.

Add newhashinit(), which is identical to hashinit() except it takes a flags
arg for passing to malloc() (hashinit always uses M_WAITOK which is not
always what you want).  Everything that uses hashinit should really
get converted to newhashinit and then newhashinit can be renamed.
