f1a508e354 Prevent deadlock cited in PR4629 from crashing the system. (copyout

presumably have to wait for UBC and/or for vnode locking protocols to
be revamped to allow use of shared locks.

8a931fcdd8 Ensure that you can only bind a more specific address when it is done by the
same uid or by root.

This code is from FreeBSD. (Whilst it was originally obtained from OpenBSD,
FreeBSD fixed it to work with multicast. To quote the commit message:
    - Don't bother checking for conflicting sockets if we're binding to a
      multicast address.
    - Don't return an error if we're binding to INADDR_ANY, the conflicting
      socket is bound to INADDR_ANY, and the conflicting socket has
      SO_REUSEPORT set.

098b6f8e8a Disallow descriptor-passing of descriptors which are open on
directories which aren't under the recipient's root.

Clean up of many error conditions involving descriptor passing, to
eliminate infinite loops, panics, premature garbage collection of
sockets, and descriptor leaks:
 - Avoid letting unp_gc() see descriptors with a refcount of zero by
removing them from the socket's queue before releasing them.
 - Avoid socket leak in PRU_ABORT (this will also gc descriptors queued
on a not-yet accepted socket when the accepting socket goes away).
 - Put in block comment explaining how unp_gc() should work.
 - Correctly manage unp_defer count so we don't get stuck in an infinite
loop with nothing to do.
 - Don't tie MARK and DEFER bits so closely together.
 - Mark descriptors queued on not-yet-accepted sockets as well.
 - Don't call sorflush on non-socket, it doesn't work very well.
 - Deal with discard of NULL file pointer.
 - Hopefully cause GC to converge faster by only deferring sockets in
unp_mark().

2f0f84b8e8 bug fix to fdavail: be consistent about taking per-process descriptor
limit into account when checking against the limit; fdp->fd_nfiles may
be greater than the current descriptor limit, and there may be space
in fdp->fd_ofiles beyond the limit.  If we say it's available,
unp_externalize will get confused and panic when fdalloc fails.

36dc99adac vinvalbuf, called from vclean, could cause a locking-against-self
deadlock in VOP_FSYNC() if the unreferenced vnode picked for
reclamation happened to be stacked on top of a vnode the process
already had locked.  This could happen if the same filesystem was
accessed both through a union mount and directly; it seemed to happen
most frequently when the direct access was through NFS.

Avoid this deadlock by changing vinvalbuf to pass a new FSYNC_RECLAIM
flag bit to VOP_FSYNC() to indicate that a reclaim is in progress and
only a `shallow' fsync is necessary.

Do nothing in *_fsync() in umapfs, nullfs, and unionfs when
FSYNC_RECLAIM is set; the underlying vnodes will shortly be released
in *_reclaim and may be reclaimed (and fsync'ed) later.

c0fb2ab4f2 Use a SETRECURSE lock before calling VFS_MOUNT in the mount() system call,
since the lock may be taken again. This was the intention of the CANRECURSE
lock already there, but didn't work.

Only fill in the vnode<->mountpoint links (mountedhere and vnodecovered)
after VFS_MOUNT returned succesfully. It might happen that something called
from VFS_MOUNT mistook the vnode for an already successfully mounted on
one because of this.

080ad305ff 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.

b4a33c4e60 Scheduler bug fixes and reorganization
* fix the ancient nice(1) bug, where nice +20 processes incorrectly
  steal 10 - 20% of the CPU, (or even more depending on load average)
* provide a new schedclk() mechanism at a new clock at schedhz, so high
  platform hz values don't cause nice +0 processes to look like they are
  niced
* change the algorithm slightly, and reorganize the code a lot
* fix percent-CPU calculation bugs, and eliminate some no-op code

=== nice bug === Correctly divide the scheduler queues between niced and
compute-bound processes. The current nice weight of two (sort of, see
`algorithm change' below) neatly divides the USRPRI queues in half; this
should have been used to clip p_estcpu, instead of UCHAR_MAX.  Besides
being the wrong amount, clipping an unsigned char to UCHAR_MAX is a no-op,
and it was done after decay_cpu() which can only _reduce_ the value.  It
has to be kept <= NICE_WEIGHT * PRIO_MAX - PPQ or processes can
scheduler-penalize themselves onto the same queue as nice +20 processes.
(Or even a higher one.)

=== New schedclk() mechansism === Some platforms should be cutting down
stathz before hitting the scheduler, since the scheduler algorithm only
works right in the vicinity of 64 Hz. Rather than prescale hz, then scale
back and forth by 4 every time p_estcpu is touched (each occurance an
abstraction violation), use p_estcpu without scaling and require schedhz
to be generated directly at the right frequency. Use a default stathz (well,
actually, profhz) / 4, so nothing changes unless a platform defines schedhz
and a new clock.  Define these for alpha, where hz==1024, and nice was
totally broke.

=== Algorithm change === The nice value used to be added to the
exponentially-decayed scheduler history value p_estcpu, in _addition_ to
be incorporated directly (with greater wieght) into the priority calculation.
At first glance, it appears to be a pointless increase of 1/8 the nice
effect (pri = p_estcpu/4 + nice*2), but it's actually at least 3x that
because it will ramp up linearly but be decayed only exponentially, thus
converging to an additional .75 nice for a loadaverage of one. I killed
this, it makes the behavior hard to control, almost impossible to analyze,
and the effect (~~nothing at for the first second, then somewhat increased
niceness after three seconds or more, depending on load average) pointless.

=== Other bugs === hz -> profhz in the p_pctcpu = f(p_cpticks) calcuation.
Collect scheduler functionality. Try to put each abstraction in just one
place.

Don't call the protocol drain routines if how == M_NOWAIT, which typically
means we're in interrupt context.  Since we can be called from a network
hardware interrupt, we could corrupt the protocol queues we try to drain
them at that time.

The problem has been addressed by letting the drain'able protocols use
a locking scheme to prevent queue corruption.

ab1b371163 Implement config_detach(), mostly from Chris Demetriou, modified slightly
by Ken Hornstein and myself.

Add flags to struct device, and define one as "active".  Devices are
initially active from config_attach().  Their active state may be changed
via config_activate() and config_deactivate().

These new functions assume that the device being manipulated will recursively
perform the action on its children.

Together, config_deactivate() and config_detach() may be used to implement
interrupt-driven device detachment.  config_deactivate() will take care of
things that need to be performed at interrupt time, and config_detach()
(which must run in a valid thread context) finishes the job, which may
block.

  struct proc *.

for machines where debug on panic is useful, but DDB entry is not,
(public-access console, or terminal-servers which send spurious breaks)

Add new ddb hook, console_debugger(), which decides whether or not to
ignore console ddb requests. Console drivers should be updated to call
console_debugger(), not Debugger(), in response to serial-console
break or ddb keyboard sequence.

* If a buffer is being waited for, don't put it on the age queue.
* Make sure to clear B_DONE when pages are stolen from a buffer.
* Make sure to clear B_CACHE after each use.
* If we find a buffer for the block we want with valid data, but it is too
  small, panic.  (This isn't supposed to happen.)

fb526e055c Substantial signal handling changes:
* Increase the size of sigset_t to accomodate 128 signals -- adding new
  versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
  sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
  sys_sigpending() and sys_sigsuspend() into separate functions, and call them
  from all the emulations rather than hard-coding everything.  (Avoids uses
  the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
  pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
  bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
  in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.

Note: Only code touched by the i386 port has been modified.  Other ports and
emulations need to be updated.

3c658f1f41 Don't call the protocol drain routines if how == M_NOWAIT, which typically
means we're in interrupt context.  Since we can be called from a network
hardware interrupt, we could corrupt the protocol queues we try to drain
them at that time.

c56c24f4fd Initialize the mbuf allocator _before_ autoconfiguration; it might be
called when devices attach, take two.

Note that it is necessary that mbinit() NOT allocate memory, since it
is called before mb_map is created.  This is not a problem with the
pool allocator that is now used for mbufs and mbuf clusters.

4b039671de When checking for overflow in the residual count, test against SSIZE_MAX.
The read/write system calls return ssize_t because -1 is used to indicate
error, therefore the transfer size MUST be limited to SSIZE_MAX, otherwise
garbage can be returned to the user.

There is NO change from existing behavior here, only a more precise
definition of that the semantics are, except in the Alpha case, where
the full SSIZE_MAX transfer size can now be realized (ssize_t is 64-bit
on the Alpha).

fc4828b0b4 A few small changes to how pool pages are allocated/freed:
- If either an alloc or release function is provided, make sure both are
  provided, otherwise panic, as this is a fatal error.
- If using the default allocator, default the pool pagesz to PAGE_SIZE,
  since that is the granularity of the default allocator's mechanism.
- In the default allocator, use new functions:
	uvm_km_alloc_poolpage()/uvm_km_free_poolpage(), or
	kmem_alloc_poolpage()/kmem_free_poolpage()
  rather than doing it here.  These functions may use pmap hooks to
  provide alternate methods of mapping pool pages.
