TCP/IPv6 packets to be forwarded can be laid out with only the Ethernet
header in the first mbuf, and these packets are lost. There was a
previous hack to pullup ICMPv6 packets with such a layout for the
same reason. Generalize, and pullup any IPv6 packets with only the
Ethernet header in the first mbuf. Possibly this should also include
IPv4, but that situation has not been observed to fail.

After length decisions, we've decided that the if_wg(4) driver and
related work is not yet ready to live in the tree. This driver has
larger security implications than many, and thus will be held to
more scrutiny than other drivers.
Please also see the related message sent to the freebsd-hackers@
and freebsd-arch@ lists by Kyle Evans <kevans@FreeBSD.org> on
2021/03/16, with the subject line "Removing WireGuard Support From Base"
for additional context.
These ioctl commands aim to provide easier ways for user space
applications to enumerate existing audio devices and the node they can
potentially use.
The exchange of device lists between user space and kernel is done on
nv(9). Some ioctl commands are added to /dev/sndstat node:
- SNDSTAT_REFRESH_DEVS
- SNDSTAT_GET_DEVS
- SNDSTAT_ADD_USER_DEVS
- SNDSTAT_FLUSH_USER_DEVS
Bump __FreeBSD_version to reflect the addition of the ioctls.

This is the culmination of about a week of work from three developers to
fix a number of functional and security issues. This patch consists of
work done by the following folks:
- Jason A. Donenfeld <Jason@zx2c4.com>
- Matt Dunwoodie <ncon@noconroy.net>
- Kyle Evans <kevans@FreeBSD.org>
Notable changes include:
- Packets are now correctly staged for processing once the handshake has
completed, resulting in less packet loss in the interim.
- Various race conditions have been resolved, particularly w.r.t. socket
and packet lifetime (panics)
- Various tests have been added to assure correct functionality and
tooling conformance
- Many security issues have been addressed
- if_wg now maintains jail-friendly semantics: sockets are created in
the interface's home vnet so that it can act as the sole network
connection for a jail
- if_wg no longer fails to remove peer allowed-ips of 0.0.0.0/0
- if_wg now exports via ioctl a format that is future proof and
complete. It is additionally supported by the upstream
wireguard-tools (which we plan to merge in to base soon)
- if_wg now conforms to the WireGuard protocol and is more closely
aligned with security auditing guidelines
Note that the driver has been rebased away from using iflib. iflib
poses a number of challenges for a cloned device trying to operate in a
vnet that are non-trivial to solve and adds complexity to the
implementation for little gain.
The crypto implementation that was previously added to the tree was a
super complex integration of what previously appeared in an old out of
tree Linux module, which has been reduced to crypto.c containing simple
boring reference implementations. This is part of a near-to-mid term
goal to work with FreeBSD kernel crypto folks and take advantage of or
improve accelerated crypto already offered elsewhere.
There's additional test suite effort underway out-of-tree taking
advantage of the aforementioned jail-friendly semantics to test a number
of real-world topologies, based on netns.sh.
Also note that this is still a work in progress; work going further will
be much smaller in nature.

This lets one interrupt DDB's output, which is useful if paging is
disabled and the output device is slow.
This follows a previous implementation in svn r311952 / git
5fddef7999 which was reverted because it
broke DDB type-ahead.
Now, try this again, but with a 512-byte type-ahead buffer. While there
is buffer space, control input is handled and non-control input is
buffered. When the buffer is exhausted, the default is to print a
warning and drop further non-control input in order to continue handling
control input. sysctl debug.ddb.prioritize_control_input can be set to
0 to instead preserve all input but lose immediate handling of control
input. This could for example effect pasting of a large script into the
ddb console.

TSFOOR happens if a beacon with a given TSF isn't received within the
programmed/expected TSF value, plus/minus a fudge range. (OOR == out of range.)
If this happens then it could be because the baseband/mac is stuck, or
the baseband is deaf. So, do a cold reset and resync the beacon to
try and unstick the hardware.
It also happens when a bad AP decides to err, slew its TSF because they
themselves are resetting and they don't preserve the TSF "well."
This has fixed a bunch of weird corner cases on my 2GHz AP radio upstairs
here where it occasionally goes deaf due to how much 2GHz noise is up
here (and ANI gets a little sideways) and this unsticks the station
VAP.
For AP modes a hung baseband/mac usually ends up as a stuck beacon
and those have been addressed for a long time by just resetting the
hardware. But similar hangs in station mode didn't have a similar
recovery mechanism.
Tested:
* AR9380, STA mode, 2GHz/5GHz
* AR9580, STA mode, 5GHz
* QCA9344 SoC w/ on-board wifi (TL-WDR4300/3600 devices); 2GHz
STA mode
Right now ts_antenna is either 0 or 1 in each supported HAL so
this is purely a sanity check.
Later on if I ever get magical free time I may add some extensions
for the NICs that can have slightly more complicated antenna switches
for transmit and I'd like this to not bust memory.
Implement a driver for the RTC embedded in the RK805/RK808 power
management system used for RK3328 and RK3399 SoCs.
Based on experiments on my RK808, setting the time doesn't alter the
internal/inaccessible sub-second counter, therefore there's no point
in calling clock_schedule().

We have seen several cases of processes which have become "stuck" in
kern_sigsuspend(). When this occurs, the kernel's td_sigblock_val
is set to 0x10 (one block outstanding) and the userspace copy of the
word is set to 0 (unblocked). Because the kernel's cached value
shows that signals are blocked, kern_sigsuspend() blocks almost all
signals, which means the process hangs indefinitely in sigsuspend().
It is not entirely clear what is causing this condition to occur.
However, it seems to make sense to add some protection against this
case by fetching the latest sigfastblock value from userspace for
syscalls which will sleep waiting for signals. Here, the change is
applied to kern_sigsuspend() and kern_sigtimedwait().
