Several users with alc(4)-based "Killer" Ethernet cards have reported
issues with this driver not passing traffic, which are solved by
disabling MSI-X using the provided tunable.
To work around this issue, disable MSI-X by default on this card.
This is done by having msix_disable default to 2, which means
"auto-detect". The user can still override this to either 0 or 1 as
desired.
Since these are slow (1Gbps) Ethernet ICs used in low-end systems, it's
unlikely this will cause any practical performance issues; on the other
hand, the card not working by default likely causes issues for many new
FreeBSD users who find their network port doesn't work and have no idea
why.

- Remove superfluous whitespace by removing trailing whitespace
before `\` (line continuation character)
- Quote `SUBDIR.` to clarify the fact that this is a variable
reference--not the end of a sentence.
When in netmap (emulated) mode, wireguard interfaces prepend or strip a
dummy ethernet header when interfacing with netmap. The netmap
application thus sees unencrypted, de-encapsulated frames with a fixed
header.
In this mode, netmap hooks the if_input and if_transmit routines of the
ifnet. Packets from the host TX ring are handled by wg_if_input(),
which simply hands them to the netisr layer; packets which would
otherwise be tunneled are intercepted in wg_output() and placed in the
host RX ring.
The "physical" TX ring is processed by wg_transmit(), which behaves
identically to wg_output() when netmap is not enabled, and packets
appear in the "physical" RX ring by hooking wg_deliver_in().

Hot-unplugging a sound device, such as a USB sound card, whilst being
consumed by an application, results in an infinite loop until either the
application closes the device's file descriptor, or the channel
automatically times out after hw.snd.timeout seconds. In the case of a
detach however, the timeout approach is still not ideal, since we want
all resources to be released immediatelly, without waiting for N seconds
until we can use the bus again.
The timeout mechanism works by calling chn_sleep() in chn_read() and
chn_write() (see pcm/channel.c) in order to send the thread to sleep,
using cv_timedwait_sig(). Since chn_sleep() sets the CHN_F_SLEEPING flag
while waiting for cv_timedwait_sig() to return, we can test this flag in
pcm_unregister() (called during detach) and wakeup the sleeping
thread(s) to immediately kill the channel(s) being consumed.

As mentioned in zpoolprops(7), on some SSDs, it may not be desirable to
use ZFS autotrim because a large number of trim requests can degrade
disk performance; instead, the pool should be manually trimmed at
regular intervals.
Add a new daily periodic script for this purpose, 801.trim-zfs. If
enabled (daily_trim_zfs_enable=YES; the default is NO), it will run a
'zpool trim' operation on all online pools, or on the pools listed in
'daily_trim_zfs_pools'.
The trim is not started if the pool is degraded (which matches the
behaviour of the existing 800.scrub-zfs script) or if a trim is already
running on that pool. Having autotrim enabled does not inhibit the
periodic trim; it's sometimes desirable to run periodic trims even with
autotrim enabled, because autotrim can elide trims for very small

Perhaps install should grow smarts to know when this is the case, though

Debugging boot issues can be helped by
logging each rc.d script as it is run
and being able to selectively enable/disable set -x
debug.sh provides an elaborate framework for debugging shell scripts.
For secure systems, we want to be paranoid about what we read
during boot.
dot() simply reads (.) arg file if it exists
vdot() if mac_veriexec is active, ignore unverified files
otherwise behaves much the same as dot()
safe_dot() in safe_eval.sh allows reading an untrusted file;
limiting the input to simple variable assignments.
In load_rc_config allow caller to provide an option to indicate how to
handle its arg:
-v use vdot()
-s use sdot() which will try to use vdot() and fallback to safe_dot()
The default is to read using dot()
rc_run_scripts()
encapsulate the running of rc.d scripts
so that we can easily call it more than twice.
We vdot local.rc.subr to pick up extensions (like
run_rc_scripts_final) and overrides.
We also allow rc.subr.local or rc.conf to set rc_config_xtra
eg (rc_config_xtra=XXX for historic compatibility)
rc use set -o verify around the reading in of rc.subr
This has no effect if mac_veriexec is not active, but if it is; ensures
rc.subr has not been tampered with.

This socket option was added in 6a2989fd54 together with LOCAL_CREDS.
Both options originate from NetBSD. The LOCAL_CREDS seems to be used by
some software and is covered by our test suite.
The main problem with LOCAL_CONNWAIT is that it doesn't work as
documented. A basic test shows that connect(2) indeed blocks, but
accept(2) on the other side does not wake it up. Indeed, I don't see what
code in the accept(2) path would go into the peer socket of a unix/stream
listener's child and would make wakeup(&so->so_timeo). I tried the test
even on a FreeBSD 6.4-RELEASE and it produced the same results as on
CURRENT.
The other thing that puzzles me is why that option would be useful even if
it worked? Because on unix/stream you can send(2) immediately after
connect(2) and that would put data on the peer receive buffer even before
listener had done accept(2). In other words, one side can do connect(2)
then send(2), only after the remote side would make accept(2) and the
remote would see the data sent before the accept(2). Again this
undocumented feature of unix(4) is present on all versions from FreeBSD 6

libsys provides the FreeBSD kernel interface (auxargs, system calls,
vdso). It can be linked directly for programs using a non-standard
libc and will later be linked as a filter library to libc providing
the actual system call implementation.

Not all of the tree is happy for realinstall to be done in parallel. In
particular, Makefile.inc1 uses .WAIT to force etc to be installed after
earlier subdirectories, since etc calls into share/man's makedb to run
makewhatis on the tree and needs all manpages to have been installed.
Also, libexec/Makefile doesn't set SUBDIR_PARALLEL, and the link from
ld-elf32.1 to ld-elf.1 relies on rtld-elf having been installed before
rtld-elf32, otherwise creating the link will fail.
In general, core behavioural differences like this between NO_ROOT and
"normal" builds are also dangerous and confusing.
If this optimisation is deemed important, it should be reintroduced in a
more limited and robust manner that doesn't break the above situations.
Until then value correctness over slight efficiency gains on high core
count machines, the same machines where you're more likely to encounter
issues from this optimisation.

force SUBDIR_PARALLEL for buildworld WORLDTMP staging.") and

Some hardware setups require a specific sample rate due to devices being
connected to digital ports (AES, S/PDIF, ADAT). Add a per device sysctl
"sample_rate" to let the user override sample rate requests from the pcm

Let the user choose a period (interrupt cadence in samples), in the
official RME drivers this setting is available as "Buffer Size".
Override the period propagated through blocksize by pcm channel latency
settings (see sound(4)), since these are unreliable and differ between

This function was used only in TCP before 446ccdd08e. It was born in
pain in 2016 to plug different complex panics in TCP timers. It wasn't
warmly accepted in phabricator by all of the reviewers and my recollection
of overall agreement was that "if you need this KPI, then you'd better fix
your code to not need it". However, the function served its duty well all
the way to FreeBSD 14. But now that TCP doesn't need it anymore, let's
retire it to reduce complexity of callout code and also to avoid its
further use.

device_set_descf() is a printf-like version of device_set_desc().
Allocation code has been transferred from device_set_desc_internal() to
device_set_desc_copy() and device_set_descf() to avoid complicating
device_set_desc_internal(). The "copy" argument in
device_set_desc_internal() has been replaced with a flag which is set
when the description string has been allocated with M_BUS.

ADAT connections transport 8, 4 or 2 audio channels depending on the
sample rate. Instead of splitting each physical ADAT port into 4
(potentially unmapped) stereo pcm devices, create just one pcm
device of variable channel width for every ADAT port.
Depending on the sample rate and channel width selected, the pcm
channels may be only partially mapped to ADAT channels and vice versa.
Added flexibility of the new channel mapping is also prerequisite to
introduce more pcm device layouts in follow-up commits.
