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).

7e73d40ee5 Replace a home-grown printf() clone with a fwopen() wrapper around
libc's vfprintf() that writes to a `struct output' instead of a file.
Inspired by NetBSD's similar changes (they used asprintf() instead).

0c1661b754 - Don't use quad_t when we really mean rlim_t.
- Cast rlim_t to intmax_t when printing it.

This should fix the last format errors in sh(1).

219cbe1087 Merged all interesting difference between the old math.h and the current
one into the latter and removed the former.

This works around the bug that some broken Makefiles add -I.../src/include
to CFLAGS, resulting in the old math.h being preferred and differences
between the headers possibly being fatal.

The merge mainly involves declaring some functions as __pure2 although
they are not yet all strictly free of side effects.

ec65e9977a Use the %t format modifier to print differences between
pointers.  This fixes two format warnings on 64 bits
archs which are fatal now that WFORMAT=0 has been removed.

It doesn't fully fix the sh(1) build on 64 bits platforms
though, there is still some quad_t issues that need to be
fixed.

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.

af98feb19c Use if_printf(ifp, "blah") instead of printf("fe%d: blah", ifp->if_unit).
A number of functions in this driver still use the unit number in their
printouts because they pass the unit directly as a function argument
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.

for compatability and to export one could.  For now, just tell KVM to hand
an empty signal set off to the userland.

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.
