0e2181f578 Extend IPv6 routing lookups in pf(4) to use the new multi-FIB KPI.
Try to make the "rtable" handling work but the current version of
pf(4) does not fully support it yet as especially callers of
PF_MISMATCHAW() are not fully FIB-aware.  OpenBSD seems to have
fixed this in a later version.  Prepare as much as possible.

81d5d46b3c Add multi-FIB IPv6 support to the core network stack supplementing
the original IPv4 implementation from r178888:

- Use RT_DEFAULT_FIB in the IPv4 implementation where noticed.
- Use rt*fib() KPI with explicit RT_DEFAULT_FIB where applicable in
  the NFS code.
- Use the new in6_rt* KPI in TCP, gif(4), and the IPv6 network stack
  where applicable.
- Split in6_rtqtimo() and in6_mtutimo() as done in IPv4 and equally
  prevent multiple initializations of callouts in in6_inithead().
- Use wrapper functions where needed to preserve the current KPI to
  ease MFCs.  Use BURN_BRIDGES to indicate expected future cleanup.
- Fix (related) comments (both technical or style).
- Convert to rtinit() where applicable and only use custom loops where
  currently not possible otherwise.
- Multicast group, most neighbor discovery address actions and faith(4)
  are locked to the default FIB.  Individual IPv6 addresses will only
  appear in the default FIB, however redirect information and prefixes
  of connected subnets are automatically propagated to all FIBs by
  default (mimicking IPv4 behavior as closely as possible).

should probably attached to domain(9) specific storage. [1]

Add a comment on a limitimation on the rt_add_addr_allfibs option.

Use RT_DEFAULT_FIB instead of 0 where applicable.

Add empty line to functions without local variables per style.

Put public yet unused in-tree function rtinit_fib() under BURN_BRIDGES
to indicate that it might go away in the future.

No functional change.

8f12d83ad9 Fix NULL dereference panic on attempt to turn off (on system shutdown)
disconnected swap device.

This is quick and imperfect solution, as swap device will still be opened
and GEOM will not be able to destroy it. Proper solution would be to
automatically turn off and close disconnected swap device, but with existing
code it will cause panic if there is at least one page on device, even if
it is unimportant page of the user-level process. It needs some work.

fde809356a If multiple threads call kevent() to get AIO events on same kqueue fd,
it is possible that a single AIO event will be reported to multiple
threads, it is not threading friendly, and the existing API can not
control this behavior.
Allocate a kevent flags field sigev_notify_kevent_flags for AIO event
notification in sigevent, and allow user to pass EV_CLEAR, EV_DISPATCH
or EV_ONESHOT to AIO kernel code, user can control whether the event
should be cleared once it is retrieved by a thread. This change should
be comptaible with existing application, because the field should have
already been zero-filled, and no additional action will be taken by
kernel.

1db689c583 Support AR9281/AR5B91 - a 1x2 stream device based on the AR9280.
* Override the TX/RX stream count if the EEPROM reports a single RX or
  TX stream, rather than assuming the device will always be a 2x2 strea
  device.

* For AR9280 devices, don't hard-code 2x2 stream.  Instead, allow the
  ar5416FillCapabilityInfo() routine to correctly determine things.

The latter should be done for all 11n chips now that
ar5416FillCapabilityInfo() will set the TX/RX stream count based on the
active TX/RX chainmask in the EEPROM.

Thanks to Maciej Milewski for donating some AR9281 NICs to me for
testing.

fd578f6543 Make sound(4) more flexible in setting soft buffer and block sizes when
hardware imposes strict limitations on hard buffer and block sizes.

Previous code set soft buffer to be no smaller then hard buffer. On some
cards with fixed 64K physical buffer that caused up to 800ms play latency.
New code allows to set soft buffer size down to just two blocks of the hard
buffer and to not write more then that size ahead to the hardware buffer.
As result of that change I was able to reduce full practically measured
record-playback loop delay in those conditions down to only about 115ms
with theoretical playback latency of only about 50ms.

New code works fine for both vchans and direct cases. In both cases sound(4)
tries to follow hw.snd.latency_profile and hw.snd.latency values and
application-requested buffer and block sizes as much as limitation of two
hardware blocks allows.

f11c7f6305 Add isci(4) driver for amd64 and i386 targets.
The isci driver is for the integrated SAS controller in the Intel C600
(Patsburg) chipset.  Source files in sys/dev/isci directory are
FreeBSD-specific, and sys/dev/isci/scil subdirectory contains
an OS-agnostic library (SCIL) published by Intel to control the SAS
controller.  This library is used primarily as-is in this driver, with
some post-processing to better integrate into the kernel build
environment.

isci.4 and a README in the sys/dev/isci directory contain a few
additional details.

This driver is only built for amd64 and i386 targets.

a8122d16b5 jwd@ reported a problem via email to freebsd-fs@ on Aug 25, 2011
under the subject "F_RDLCK lock to FreeBSD NFS fails to R/O target file".
This occurred because the server side NLM always checked for VWRITE
access, irrespective of the type of lock request. This patch
replaces VOP_ACCESS(..VWRITE..) with one appropriate to
the lock operation. It allows unlock and lock cancellation
to be done without a check of VOP_ACCESS(), so that files
can't be left locked indefinitely after the file permissions
have been changed.

62f8a13a75 Add a DFS debugging mode which is useful when doing automated DFS
compliance testing.

In order to allow for radar pattern matching to occur, the DFS CAC/NOL
handling needs to be made configurable.  This commit introduces a new
sysctl, "net.wlan.dfs_debug", which controls which DFS debug mode
net80211 is in.

* 0 = default, CSA/NOL handling as per normal.
* 1 = announce a CSA, but don't add the channel to the non-occupy list
  (NOL.)
* 2 = disable both CSA and NOL - only print that a radar event occured.

This code is not compiled/enabled by default as it breaks regulatory
handling.  A user must enable IEEE80211_DFS_DEBUG in their kernel
configuration file for this option to become available.
