1d56414515 - Adjust comment noting that handling of CPU limit exhaustion is done in
ast().
- Actually set KEF_ASTPENDING so ast() is called.  I think this is buggy
  for a process with multiple KSE's in that PS_XCPU is not a KSE event,
  it's a process-wide event.  IMO there really should probably be two
  ASTPENDING flags, one for per-process, and one for per-KSE.

7e3998a3de Removed the only PCI_DEBUG ifdef in the kernel. PCI_DEBUG was not a
supported option and it disabled a whole 2 lines of bootverbose messages.
I wanted to see 1 of the messages (about the latency timers).  This
is a wrong place to decode pci configurations, but the code is already
here and handles more details than pciconf(8).

3bb24c35f2 Split MBR and PC98 on-disk sliceformats out from disklabel.h, step 1:
Peter had repocopied sys/disklabel.h to sys/diskpc98.h and sys/diskmbr.h.

These two new copies are still intact copies of disklabel.h and
therefore protected by #ifndef _SYS_DISKLABEL_H_ so #including them
in programs which already include <sys.disklabel.h> is currently a
no-op.

This commit adds a number of such #includes.

Once I have verified that I have fixed all the places which need fixing,
I will commit the updated versions of the three #include files.

1aa37f5392 Improve locking of pipe mutexes in the context of MAC:
(1) Where previously the pipe mutex was selectively grabbed during
    pipe_ioctl(), now always grab it and then release if if not
    needed.  This protects the call to mac_check_pipe_ioctl() to
    make sure the label remains consistent.  (Note: it looks
    like sigio locking may be incorrect for fgetown() since we
    call it not-by-reference and sigio locking assumes call by
    reference).

(2) In pipe_stat(), lock the pipe if MAC is compiled in so that
    the call to mac_check_pipe_stat() gets a locked pipe to
    protect label consistency.  We still release the lock before
    returning actual stat() data, risking inconsistency, but
    apparently our pipe locking model accepts that risk.

(3) In various pipe MAC authorization checks, assert that the pipe
    lock is held.

(4) Grab the lock when performing a pipe relabel operation, and
    assert it a little deeper in the stack.

4499985ef2 Reserve system call numbers for the following system calls:
__mac_get_pid		Retrieve MAC label of a process by pid

Similar to __mac_get_proc() except that the target process of
the operation is explicitly specified rather than assuming
curthread.

__mac_get_link		Retrieve MAC label of a path with NOFOLLOW
__mac_set_link		Set MAC label of a path with NOFOLLOW
extattr_set_link	Set EAs on a path with NOFOLLOW
extattr_get_link	Retrieve EAs on a path with NOFOLLOW
extattr_delete_link	Delete EAs on a path with NOFOLLOW

These calls are similar to __mac_get_file(), __mac_set_file(),
extattr_set_file(), extattr_get_file(), and extattr_delete_file(),
except that they do not follow symlinks.  The distinction between
these calls is similar to lchown() vs chown().

Implementations to follow.

A number of functions in this driver still use the unit number in their

instead of passing a softc or struct ifnet pointer.  This should be
resolved at a future date.

226e1171e1 (Forced commit, to clarify previous commit of ksiginfo/signal queue code.)
I've added a structure, kernel-private, to represent a pending or in-delivery
signal, called `ksiginfo'.  It is roughly analogous to the basic information
that is exported by the POSIX interface 'siginfo_t', but more basic.  I've
added functions to allocate these structures, and further to wrap all signal
operations using them.

Once the operations are wrapped, I've added a TailQ (see queue(3)) of these
structures to 'struct proc', and all pending signals are in that TailQ.  When
a signal is being delivered, it is dequeued from the list.  Once I finish
the spreading of ksiginfo throughout the tree, the dequeued structure will be
delivered to the process in question, whereas currently and normally, the
signal number is what is used.

dc183990ca - Add a new per-process flag PS_XCPU to indicate that at least one thread
has exceeded its CPU time limit.
- In mi_switch(), set PS_XCPU when the CPU time limit is exceeded.
- Perform actual CPU time limit exceeded work in ast() when PS_XCPU is set.

0626774f08 Move vnode MAC label initialization to after the release of the vnode
interlock in getnewvnode() to avoid possible sleeps while holding
the mutex.  Note that the warning from Witness is a slight false
positive since we know there will be no contention on the interlock
since we haven't made the vnode available for use yet, but the theory
is not a bad one.

1226f694e6 First half of implementation of ksiginfo, signal queues, and such. This
gets signals operating based on a TailQ, and is good enough to run X11,
GNOME, and do job control.  There are some intricate parts which could be
more refined to match the sigset_t versions, but those require further
evaluation of directions in which our signal system can expand and contract
to fit our needs.

After this has been in the tree for a while, I will make in kernel API
changes, most notably to trapsignal(9) and sendsig(9), to use ksiginfo
more robustly, such that we can actually pass information with our
(queued) signals to the userland.  That will also result in using a
struct ksiginfo pointer, rather than a signal number, in a lot of
kern_sig.c, to refer to an individual pending signal queue member, but
right now there is no defined behaviour for such.

CODAFS is unfinished in this regard because the logic is unclear in
some places.
