"ifconfig -g groupname" prints a list of interface names,
which could be confusing, because it differs from
the behavior of "ifconfig -a -g groupname".
While here, add two examples showing the difference between
"ifconfig -a -g groupname" and "ifconfig -g groupname".

The new '-L' flag will cause savecore to invoke the new mem(4) kernel
dump ioctl, taking a dump of the running system and writing the result
to a temporary file. Validation of the dump header is performed, similar
to regular crash dumps, and the final result is written to
livecore.X[.zst|.gz].
Also added is the '-Z' flag, which instructs the kernel to compress the
livedump compressed with zstd, akin to the existing -z flag. This option
has no effect in normal savecore(8) operation, but in theory could be
extended to perform such compression while reading the dump from the
dump device.
Encryption is unsupported for live dumps.
For example: 'savecore -Lz /var/crash' would create:
/var/crash/livecore.0.gz

mount_nfs creates entries in the mounttab file and umount removes
them. Entries in the mounttab file ae used by rpc.umntall to
notify the NFS server that NFSv3 entries need to be removed when
they have not been removed by umount.
Without this patch, an enty will be created in the mounttab file,
even if the nmount(2) syscall fails for the mount. This patch
modifies the code so that the mounttab entry is only created
after nmount(2) succeeds.
This change only affects NFSv3 and only affects how showmount
displays NFSv3 mounts.

Previously we expected the DIOCSKERNELDUMP ioctl to return ENXIO if the
interface was down, but it does not actually do this. Grab the link
status using getifaddrs(3) instead, and downgrade this case from an
error to a warning; the user might bring the link back up at a later
time.

The command "ping -S dotted.quad hostname" fails on dual-stack hosts
with the confusing message "ping: invalid source address: Name does
not resolve" because IPv6 is selected in preference. If the argument
to -S is numeric (likely), select the corresponding address family,
as if -4 or -6 was specified. Add tests that either IPv4 or IPv6 can
be forced via a -S parameter.

AEAD ciphers for IPsec combine both encryption and authentication. As
such, ESP configurations using an AEAD cipher should not use a
seperate authentication algorithm via -A. However, this was not
apparent from the setkey manpage and 12.x and earlier did not perform
sufficient argument validation permitting users to pair an explicit -A
such as SHA256-HMAC with AES-GCM. (The result was a non-standard
combination of AES-CTR with the specified MAC, but with the wrong
initial block counter (and thus different keystream) compared to using
AES-CTR as the cipher.)
Attempt to clarify this in the manpage by explicitly calling out AEAD
ciphers (currently only AES-GCM) and noting that AEAD ciphers should
not use -A.
While here, explicitly note which authentication algorithms can be
used with esp vs esp-old. Also add subsection headings for the
different algorithm lists and tidy some language.
I did not convert the tables to column lists (Bl -column) though that
would probably be more correct than using literal blocks (Bd
-literal).

Therefore, we do not need character buffers to be PATH_MAX bytes long,
just long enough to hold the complete filename. 32 bytes is long enough

Traditionally the GEOM's primary channel of information from kernel to
user-space was confxml, fetched by libgeom through kern.geom.confxml
sysctl. It is convenient and informative, representing full state of
GEOM in a single XML document. But problems start to arise on systems
with hundreds of disks, where the full confxml size reaches many
megabytes, taking significant time to first write it and then parse.
This patch introduces alternative solution, allowing to fetch much
smaller XML document, subset of the full confxml, limited to 64KB and
representing only one specified geom and optionally its parents. It
uses existing GEOM control interface, extended with new "getxml" verb.
In case of any error, such as the buffer overflow, it just transparently
falls back to traditional full confxml. This patch uses the new API in
user-space GEOM tools where it is possible.
