adjtime(2): Handle negative tv_sec and tv_usec.

Previously I clamped these to avoid dangerous arithmetic overflow.
But I assumed sensible values should be nonnegative.

For tv_sec, this assumption was just wrong -- the adjustment may be
negative.

For tv_usec, this assumption is...not wrong, but also not right.
tv_usec is not _supposed_ to be negative (by POSIX, the type need
only represent values in [-1, 1000000]; semantically the member is
supposed to be a nonnegative number of microseconds below 1000000),
but ntp abuses it to hold negative values, for reasons unclear -- the
same effect could be had by subtracting one from tv_sec, and adding
1000000 to the negative tv_usec.  However, let's not break existing
ntp userlands...

A couple of tweaks to the previous re-factor:

- Some of what was defined as "generic itimer" behavior turned out to be
  ptimer-specific.  As such, everything related to the "fired timer queue"
  is now specific to ptimers, and the queue and softint handle fields of
  itimer_ops are not needed.

- Split itimer_fini() into 2 parts: itimer_poision() marks the timer as
  dead and attempts to cancel it.  itimer_fini() is then just responsible
  for freeing itimer resources and releasing the lock.  They are split
  into two parts, as ptimers require an addition processing step between
  those two operations, but other kinds of itimers do not necessarily require
  that.

- Export a few more itimer-related symbols that other itimer types will
  need.

Riding previous kernel version bump since there are no external uses of
this code since the version bump that accompanied the original change.

Refactor interval timers to make it possible to support types other than
the BSD/POSIX per-process timers:

- "struct ptimer" is split into "struct itimer" (common interval timer
  data) and "struct ptimer" (per-process timer data, which contains a
  "struct itimer").

- Introduce a new "struct itimer_ops" that supplies information about
  the specific kind of interval timer, including it's processing
  queue, the softint handle used to schedule processing, the function
  to call when the timer fires (which adds it to the queue), and an
  optional function to call when the CLOCK_REALTIME clock is changed by
  a call to clock_settime() or settimeofday().

- Rename some fuctions to clearly identify what they're operating on
  (ptimer vs itimer).

- Use kmem(9) to allocate ptimer-related structures, rather than having
  dedicated pools for them.

kern_time: prevent the system clock from being set too low or high

currently doing this will drive KUBSAN haywire and possibly cause
system lock-ups, so more testing should probably be performed before
we let the clock be set too many thousands of years into the future.

ditto for negative values, which were being passed by chrony for
some reason while my internet connection was being unreliable.
this also triggered some interesting KUBSAN reports.

- Eliminate the global "boottime" variable, which was being accessed
  without any synchronization against changes by e.g. clock_settime().
- Replace with new getbinboottime() / getnanoboottime() / getmicroboottime()
  functions (naming mirrors that of other time access functions in kern_tc.c).
  It returns the (maybe-converted) value of timebasebin, which also tracks
  our estimate of when the system was booted (i.e. the legacy "boottime" was
  redundant).

XXX There needs to be a lockless synchronization mechanism for reading
timebasebin, but this is a problem in kern_tc.c that pre-existed these
"boottime" changes.  At least now the problem is centralized in one location.

Fix the code that deals with very long sleeps (> 248 days) which
go beyond the maximum that the callout mechanism can handle.
[See the comments in tvtohz() in subr_sleep.c for the details.]

When that happens the timeout is clamped to MAX_INT (ticks), and the
code in nanosleep1() looped (or tried to) repeating the sleep (aka
kpause()) until the requested end time for the sleep was reached.

Unfortunately, the code assumed that kpause() would return 0 when
it returned after the timeout expired.   But it doesn't, it returns
EWOULDBLOCK instead (why is incomprehensible to me, but I assume
there is a reason.)   [That comes from sleepq_block() which returns
EWOULDBLOCK when callout_halt() indicates that the callout had fired,
which is exactly what has happened when the time has elapsed.]

There was already code to deal with that EWOULDBLOCK and return 0
instead of an error in that case - but it was placed after the
error code was tested against 0 for the purposes of the loop.

Simply move the EWOULDBLOCK->0 mapping earlier, so the code which
is expecting "error == 0" to mean "nothing went wrong" actually
gets to see that happen, and the loop can actually loop.

(Someday the loop should probably be rewritten as a loop, instead of
as a bunch of code followed by a "goto again"!)

Adjust locking on the sadata::sa_vps list. The main time we
walk the list, we're looking for a vp to do something with. We do
this in the signal code and in the timer code. The signal code already
runs with proc::p_lock held, so it's a very natural lock to use. The
timer code, however, calls into the sa timer code with a spinlock held.
Since proc::p_lock is an adaptable mutex, we can sleep to get it. Sleeping
with a spinlock is BAD. So proc::p_lock is _not_ the right lock there,
and something like sadata::sa_mutex would be best.

Address this difficulty by noting that both uses actually just read
the list. Changing the list of VPs is rare - once one's added, it stays
until the process ends. So make the locking protocol that to write the
list you have to hold both proc::p_lock and sadata::sa_mutex (taken
in that order). Thus holding either one individually grants read access.

This removes a case where we could sleep with timer_lock, a spinlock at
IPL_SCHED (!!), while trying to get p_lock. If that ever happened, we'd
pretty much be dead. So don't do that!

This fixes a merge botch from how I handled our gaining p_lock - p_lock
should not have simply replaced p_smutex.

While here, tweak the sa_unblock_userret() code for the case
when the blessed vp is actually running (on another CPU). Make its
resched RESCHED_IMMED so we whack the CPU. Addresses a hang I've
observed in starting firefox on occasion when I see one thread running
in userland and another thread sitting in lwpublk, which means it's on
the list of threads for which we need an unblocked upcall. This list is
one on which things should NOT linger.

Network protocol interrupts can now block on locks, so merge the globals
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:

- Inspecting process state requires thread context, so signals can no longer
  be sent from a hardware interrupt handler. Signal activity must be
  deferred to a soft interrupt or kthread.

- As the proc state locking is simplified, it's now safe to take exit()
  and wait() out from under kernel_lock.

- The system spends less time at IPL_SCHED, and there is less lock activity.

First take at security model abstraction.

- Add a few scopes to the kernel: system, network, and machdep.

- Add a few more actions/sub-actions (requests), and start using them as
  opposed to the KAUTH_GENERIC_ISSUSER place-holders.

- Introduce a basic set of listeners that implement our "traditional"
  security model, called "bsd44". This is the default (and only) model we
  have at the moment.

- Update all relevant documentation.

- Add some code and docs to help folks who want to actually use this stuff:

  * There's a sample overlay model, sitting on-top of "bsd44", for
    fast experimenting with tweaking just a subset of an existing model.

    This is pretty cool because it's *really* straightforward to do stuff
    you had to use ugly hacks for until now...

  * And of course, documentation describing how to do the above for quick
    reference, including code samples.

All of these changes were tested for regressions using a Python-based
testsuite that will be (I hope) available soon via pkgsrc. Information
about the tests, and how to write new ones, can be found on:

	http://kauth.linbsd.org/kauthwiki

NOTE FOR DEVELOPERS: *PLEASE* don't add any code that does any of the
following:

  - Uses a KAUTH_GENERIC_ISSUSER kauth(9) request,
  - Checks 'securelevel' directly,
  - Checks a uid/gid directly.

(or if you feel you have to, contact me first)

This is still work in progress; It's far from being done, but now it'll
be a lot easier.

Many thanks to YAMAMOTO Takashi, Matt Thomas, and Christos Zoulas for help
stablizing kauth(9).

Full credit for the regression tests, making sure these changes didn't break
anything, goes to Matt Fleming and Jaime Fournier.

Happy birthday Randi! :)

Implement a few changes needed to properly resolve PR#30924, as
discussed in the PR.

- introduce sys/timevar.h to hold kernel-specific stuff relevant to
  sys/time.h.  Ideally, timevar.h would contain all (or almost) of the
  #ifdef _KERNEL part of time.h, but that's a pretty big and tedious
  change to make.  For now, it will contain only the prototypes I
  introduced when working on COMPAT_NETBSD32.

- split copyinout_t into copyin_t and copyout_t, it makes prototypes more
  explicit about the meaning of a given argument.  Suggested by yamt@.

- move copyinout_t definition in sys/time.h to systm.h as copyin_t and
  copyout_t

avoid calling into the pool code while holding sched_lock
since both pool_get() and pool_put() can call wakeup().
instead, allocate the struct sadata_upcall before taking
sched_lock in mi_switch() and free it after releasing sched_lock.

clean up some modularity warts by adding a callback to
struct sadata_upcall for freeing sa_arg.

Apply the NFS exports list rototill patch:

- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
  function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
  file sys/nfs/nfs_export.c.  The former was becoming large and its code
  is always compiled, regardless of the build options.  Using the latter,
  the code is only compiled in when NFSSERVER is enabled.  While doing this,
  also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
  path and a set of export entries.  At the moment it can only clear the
  exports list or append entries, one by one, but it is done in a way that
  allows setting the whole set of entries atomically in the future (see the
  comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
  that it becomes file system agnostic.  In fact, all this whole thing was
  done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
  exports initialization; done internally by the kernel when initializing
  the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
  subsystems can run arbitrary code upon receipt of specific VFS events.
  At the moment, this only provides support for unmount and is used to
  destroy NFS exports lists from the file systems being unmounted, though it
  has room for extension.

Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments

kernel part of no-syscall upcall stack return:  libpthread registers
an offset between ss_sp and struct sa_stackinfo_t (located in struct
__pthread_st) when calling sa_register.  The kernel increments the
sast_gen counter in struct sastack when an upcall stack is used.
libpthread increments the sasi_stackgen counter in struct
sa_stackinfo_t when an upcall stack is freed.  The kernel compares the
two counters to decide if a stack is free or in use.

- add struct sa_stackinfo_t with sasi_stackgen to count stack use in
  userland
- add sast_gen to struct sastack to count stack use in kernel
- add SA_FLAG_STACKINFO to enable the stackinfo_offset argument in the
  sa_register syscall
- add sa_stackinfo_offset to struct sadata for offset between ss_sp
  and struct sa_stackinfo_t
- add ssize_t stackinfo_offset argument to sa_register, initialize
  struct sadata's sa_stackinfo_offset from it if SA_FLAG_STACKINFO is
  set
- add sa_getstack, sa_getstack0, sa_stackused and sa_setstackfree
  functions to find/use/free upcall stacks and use these where
  appropriate
- don't record stack for upcall in sa_upcall0
- pass sau to sa_switchcall instead of l2 (l2 = curlwp in sa_switchcall)
- add sa_vp_blocker to struct sadata to pass recently blocked lwp to
  sa_switchcall
- delay finding a stack for blocked upcalls to sa_switchcall
- add sa_stacknext to struct sadata pointing to next most likely free
  upcall stack; also g/c sa_stackslist in struct sadata and sast_list
  in struct sastack
- add L_SA_WOKEN flag: LWP is on sa_woken queue
- add L_SA_RECYCLE flag: LWP should be recycled in sa_setwoken
- replace l_upcallstack with L_SA_WOKEN/L_SA_RECYCLE/L_SA_BLOCKING
  flags
- g/c now unused sast_blocker in struct sastack
- make sa_switchcall, sa_upcall0 and sa_upcall_getstate static in
  kern_sa.c
- call sa_upcall_userret only once in userret
- split sa_makeupcalls out of sa_upcall_userret and use to process

- on process exit: mark LWPs sleeping in saunblock interruptible; also
  there are no LWPs sleeping on l->l_upcallstack anymore; also clear
  sa_wokenq_head to prevent unblocked upcalls

additional changes:
- cleanup timerupcall sa_vp == curlwp check
- add check in sa_yield if we didn't block on our way here and we
  wouldn't any longer be the LWP on the VP
- invalidate sa_vp_ofaultaddr after resolving pagefault

eliminate uvm_useracc() in favor of checking the return value of
copyin() or copyout().

uvm_useracc() tells us whether the mapping permissions allow access to
the desired part of an address space, and many callers assume that
this is the same as knowing whether an attempt to access that part of
the address space will succeed.  however, access to user space can
fail for reasons other than insufficient permission, most notably that
paging in any non-resident data can fail due to i/o errors.  most of
the callers of uvm_useracc() make the above incorrect assumption.  the
rest are all misguided optimizations, which optimize for the case
where an operation will fail.  we'd rather optimize for operations
succeeding, in which case we should just attempt the access and handle
failures due to insufficient permissions the same way we handle i/o
errors.  since there appear to be no good uses of uvm_useracc(), we'll
just remove it.

Cleanup signal delivery for SA processes:
General idea:  only consider the LWP on the VP for signal delivery, all
other LWPs are either asleep or running from waking up until repossessing
the VP.

- in kern_sig.c:kpsignal2: handle all states the LWP on the VP can be in
- in kern_sig.c:proc_stop: only try to stop the LWP on the VP.  All other
  LWPs will suspend in sa_vp_repossess() until the VP-LWP donates the VP.
  Restore original behaviour (before SA-specific hacks were added) for
  non-SA processes.
- in kern_sig.c:proc_unstop: only return the LWP on the VP
- handle sa_yield as case 0 in sa_switch instead of clearing L_SA, add an
  L_SA_YIELD flag
- replace sa_idle by L_SA_IDLE flag since it was either NULL or == sa_vp

Also don't output itimerfire overrun warning if the process is already
exiting.
Also g/c sa_woken because it's not used.
Also g/c some #if 0 code.

* Shuffle some data structures so, and add a flags word to ksiginfo_t.
  Right now the only flag is used to indicate if a ksiginfo_t is a
  result of a trap.  Add a predicate macro to test for this flag.
* Add initialization macros for ksiginfo_t's.
* Add accssor macro for ksi_trap.  Expands to 0 if the ksiginfo_t was
  not the result of a trap.  This matches the sigcontext trapcode semantics.
* In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal.
  Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles
  the case of non-trap-generated signals that have a > 0 si_code.

This patch fixes a signal delivery problem with threaded programs noted by

Change the contract for timer_settime() (the internal routine, not the
syscall sys_timer_settime()) to take an absolute value for realtime
timers. This avoids a pair of gratiuitous conversions with the
possibility that the timer's intermediate value would be 0.0, which
would signal timer_settime() to cancel the timer.

Adjust callers of timer_settime() to compensate; catch the case where
sys_timer_settime() with an absolute time value of now and a virtual
timer would also be subtracted down to a timer-cancelling 0.0.

This should fix the bug seen in libpthread's nanosleep() where certain
applications, such as xmms, would wedge with unexpired userlevel
alarms.

PR/8657: z@rentaboat.se: alarm takes more seconds that it can handle.

This is a followup to PR/14558.

    - itimerfix(9) limited the number of seconds to 100M, before I changed
      it to 1000M for PR/14558.
    - nanosleep(2) documents a limit of 1000M seconds.
    - setitimer(2), select(2), and other library functions that indirectly
      use setitimer(2) for example alarm(3) don't specify a limit.

So it only seems appropriate that any positive number of seconds in
struct timeval should be accepted by any code that uses itimerfix(9)
directly, except nanosleep(2) which should check for 1000M seconds
manually. This changes makes the manual pages of select(2), nanosleep(2),
setitimer(2), and alarm(3) consistent with the code.

Track which process a CPU is running/has last run on by adding a
p_cpu member to struct proc.  Use this in certain places when
accessing scheduler state, etc.  For the single-processor case,
just initialize p_cpu in fork1() to avoid having to set it in the
low-level context switch code on platforms which will never have
multiprocessing.

While I'm here, comment a few places where there are known issues
for the SMP implementation.

First sweep at scheduler state cleanup.  Collect MI scheduler
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

Change the semantics of splsoftclock() to be like other spl*() functions,
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.
