c207ff9319 Always send log(9) messages to the message buffer.
It is truer to the semantics of logging for messages to *always*
go to the message buffer, where they can eventually be collected
and, in fact, be put into a log file.

This restores the behavior prior to r70239, which seems to have
changed it inadvertently.

f4d281428f Add a new flag, SBUF_INCLUDENUL, and new get/set/clear functions for flags.
The SBUF_INCLUDENUL flag causes the nulterm byte at the end of the string
to be counted in the length of the data.  If copying the data using the
sbuf_data() and sbuf_len() functions, or if writing it automatically with
a drain function, the net effect is that the nulterm byte is copied along
with the rest of the data.

d85550b2c7 Don't specify a function name in the example SDT(9) probe. As with the
module component, it is a bug that the SDT(9) KPI allows one to specify the
function component of an SDT probe. Currently, the module component is
filled in automatically if left unset; this is not yet true for the function
component, but will be addressed by some ongoing work.

1a26c3c047 Major callout subsystem cleanup and rewrite:
- Close a migration race where callout_reset() failed to set the
  CALLOUT_ACTIVE flag.
- Callout callback functions are now allowed to be protected by
  spinlocks.
- Switching the callout CPU number cannot always be done on a
  per-callout basis. See the updated timeout(9) manual page for more
  information.
- The timeout(9) manual page has been updated to reflect how all the
  functions inside the callout API are working. The manual page has
  been made function oriented to make it easier to deduce how each of
  the functions making up the callout API are working without having
  to first read the whole manual page. Group all functions into a
  handful of sections which should give a quick top-level overview
  when the different functions should be used.
- The CALLOUT_SHAREDLOCK flag and its functionality has been removed
  to reduce the complexity in the callout code and to avoid problems
  about atomically stopping callouts via callout_stop(). If someone
  needs it, it can be re-added. From my quick grep there are no
  CALLOUT_SHAREDLOCK clients in the kernel.
- A new callout API function named "callout_drain_async()" has been
  added. See the updated timeout(9) manual page for a complete
  description.
- Update the callout clients in the "kern/" folder to use the callout
  API properly, like cv_timedwait(). Previously there was some custom
  sleepqueue code in the callout subsystem, which has been removed,
  because we now allow callouts to be protected by spinlocks. This
  allows us to tear down the callout like done with regular mutexes,
  and a "td_slpmutex" has been added to "struct thread" to atomically
  teardown the "td_slpcallout". Further the "TDF_TIMOFAIL" and
  "SWT_SLEEPQTIMO" states can now be completely removed. Currently
  they are marked as available and will be cleaned up in a follow up
  commit.
- Bump the __FreeBSD_version to indicate kernel modules need
  recompilation.
- There has been several reports that this patch "seems to squash a
  serious bug leading to a callout timeout and panic".

2a8c860fe3 In order to reduce use of M_EXT outside of the mbuf allocator and
socket-buffer implementations, introduce a return value for MCLGET()
(and m_cljget() that underlies it) to allow the caller to avoid testing
M_EXT itself.  Update all callers to use the return value.

With this change, very few network device drivers remain aware of
M_EXT; the primary exceptions lie in mbuf-chain pretty printers for
debugging, and in a few cases, custom mbuf and cluster allocation
implementations.

NB: This is a difficult-to-test change as it touches many drivers for
which I don't have physical devices.  Instead we've gone for intensive
review, but further post-commit review would definitely be appreciated
to spot errors where changes could not easily be made mechanically,
but were largely mechanical in nature.

sys/kern_subr_taskqueue.c:
	Modify taskqueue_drain_all() processing to use a temporary
	"barrier task", rather than rely on a user task that may
	be destroyed during taskqueue_drain_all()'s execution.  The
	barrier task is queued behind all previously queued tasks
	and then has its priority elevated so that future tasks
	cannot pass it in the queue.

	Use a similar barrier scheme to drain threads processing
	current tasks.  This requires taskqueue_run_locked() to
	insert and remove the taskqueue_busy object for the running
	thread for every task processed.

08fca7a56b Add some new modes to OpenCrypto. These modes are AES-ICM (can be used
for counter mode), and AES-GCM.  Both of these modes have been added to
the aesni module.

Included is a set of tests to validate that the software and aesni
module calculate the correct values.  These use the NIST KAT test
vectors.  To run the test, you will need to install a soon to be
committed port, nist-kat that will install the vectors.  Using a port
is necessary as the test vectors are around 25MB.

All the man pages were updated.  I have added a new man page, crypto.7,
which includes a description of how to use each mode.  All the new modes
and some other AES modes are present.  It would be good for someone
else to go through and document the other modes.

A new ioctl was added to support AEAD modes which AES-GCM is one of them.
Without this ioctl, it is not possible to test AEAD modes from userland.

Add a timing safe bcmp for use to compare MACs.  Previously we were using
bcmp which could leak timing info and result in the ability to forge
messages.

Add a minor optimization to the aesni module so that single segment
mbufs don't get copied and instead are updated in place.  The aesni
module needs to be updated to support blocked IO so segmented mbufs
don't have to be copied.

We require that the IV be specified for all calls for both GCM and ICM.
This is to ensure proper use of these functions.

72ba3c0822 Fix two issues with lockmgr(9) LK_CAN_SHARE() test, which determines
whether the shared request for already shared-locked lock could be
granted.  Both problems result in the exclusive locker starvation.

The concurrent exclusive request is indicated by either
LK_EXCLUSIVE_WAITERS or LK_EXCLUSIVE_SPINNERS flags.  The reverse
condition, i.e. no exclusive waiters, must check that both flags are
cleared.

Add a flag LK_NODDLKTREAT for shared lock request to indicate that
current thread guarantees that it does not own the lock in shared
mode.  This turns back the exclusive lock starvation avoidance code;
see man page update for detailed description.

Use LK_NODDLKTREAT when doing lookup(9).

On architectures where fueword() and casueword() are native, implement
fuword() and casuword() using fueword() and casuword(), to reduce
assembly code duplication.

f0188618f2 Fix multiple incorrect SYSCTL arguments in the kernel:
- Wrong integer type was specified.

- Wrong or missing "access" specifier. The "access" specifier
sometimes included the SYSCTL type, which it should not, except for
procedural SYSCTL nodes.

- Logical OR where binary OR was expected.

- Properly assert the "access" argument passed to all SYSCTL macros,
using the CTASSERT macro. This applies to both static- and dynamically
created SYSCTLs.

- Properly assert the the data type for both static and dynamic
SYSCTLs. In the case of static SYSCTLs we only assert that the data
pointed to by the SYSCTL data pointer has the correct size, hence
there is no easy way to assert types in the C language outside a
C-function.

- Rewrote some code which doesn't pass a constant "access" specifier
when creating dynamic SYSCTL nodes, which is now a requirement.

- Updated "EXAMPLES" section in SYSCTL manual page.

arguments were added to new functions named ifa_ifwithnet_fib and
ifa_ifwithdstaddr_fib, while the old functions became wrappers around the
new ones that passed RT_ALL_FIBS for the fib argument. However, the
backwards compatibility is not desired for FreeBSD 11, because there are
numerous other incompatible changes to the ifnet(9) API. We therefore
decided to remove it from head but leave it in place for stable/9 and

a695d9b25b Retire pmap_change_wiring(). We have never used it to wire virtual pages.
We continue to use pmap_enter() for that.  For unwiring virtual pages, we
now use pmap_unwire(), which unwires a range of virtual addresses instead
of a single virtual page.

d3a6879421 Nuke the never-used RF_TIMESHARE feature, reducing the complexity of the
code.  The consensus on arch@ is that this feature might have been useful
in the distant past, but is now just unnecessary bloat.

The int_rman_activate_resource() and int_rman_deactivate_resource()
functions become trivial, so manually inline them.

The special deferred handling of RF_ACTIVE is no longer needed in
reserve_resource_bound(), so eliminate the associated code at the
end of the function.

These changes reduce the object file size by more than 500 bytes on i386.

Update the rman.9 man page to reflect the removal of the RF_TIMESHARE
feature.

Not all functionality is documented; in particular:
o the *at() variants, which are useful only for implementing the
  corresponding syscalls.
o soconnect2(), also only used to implement a syscall (socketpair()).
o sockargs(), which is essentually unused and only tangentially
  socket-related.
o selsocket(), which is commented as being present solely for use by
  netncp and netsmb.
o getsockaddr(), which is just a convenience shortcut for copyin().

To reduce the diff struct pcu.cnt field was not renamed, so

45c203fce2 Remove AppleTalk support.
AppleTalk was a network transport protocol for Apple Macintosh devices
in 80s and then 90s. Starting with Mac OS X in 2000 the AppleTalk was
a legacy protocol and primary networking protocol is TCP/IP. The last
Mac OS X release to support AppleTalk happened in 2009. The same year
routing equipment vendors (namely Cisco) end their support.

Thus, AppleTalk won't be supported in FreeBSD 11.0-RELEASE.

IPX was a network transport protocol in Novell's NetWare network operating
system from late 80s and then 90s. The NetWare itself switched to TCP/IP
as default transport in 1998. Later, in this century the Novell Open
Enterprise Server became successor of Novell NetWare. The last release
that claimed to still support IPX was OES 2 in 2007. Routing equipment
vendors (e.g. Cisco) discontinued support for IPX in 2011.

Thus, IPX won't be supported in FreeBSD 11.0-RELEASE.
