- The --exclude{,-dir} and --include{,-dir} directives now match GNU
behavior of being processed in order and latest matching directive wins
- --label was previously not really documented, and -L and -l did not
indicate that --label applied to them
- The flags listed as being extensions to POSIX spec were not updated with
the removal of compression-related flags

Compression was removed so #2 goes away and everything else needs renumbered
to match, and the usage string was also updated due to removed options.

Compression support is now handled by an external script, remove it from the
bsdgrep(1) utility.
This removes the support for -Z -J -X and -M

Import the wrapper script from zstdgrep (written by wiz@netbsd.org)
Modify it to support more than just zstd (adding support for gzip,

Write a simple manpage dedicated for it.
Only use that new wrapper both for gnu grep and bsd grep

It is acceptable for syscallabi to map SV_ABI to SYSDECODE_ABI on all
architectures; libsysdecode will return not-found sentinel values if
it does not have a syscall name or errno mapping for a given
architecture.
Also, use __LP64__ for the SV_ILP32 -> SYSDECODE_ABI_LINUX32 mapping,
for any future 32- on 64-bit linuxulator implementation.

Prior to r332851:
* --exclude always win out over --include
* --exclude-dir always wins out over --include-dir
r332851 broke that behavior, resulting in:
* First of --exclude, --include wins
* First of --exclude-dir, --include-dir wins
As it turns out, both behaviors are wrong by modern grep standards- the
latest rule wins. e.g.:
`grep --exclude foo --include foo 'thing' foo`
foo is included
`grep --include foo --exclude foo 'thing' foo`
foo is excluded
As tested with GNU grep 3.1.
This commit makes bsdgrep follow this behavior.

There's no point checking for a bunch of file modes if we're not a
practicing believer of DIR_SKIP or DEV_SKIP.
This also reduces some style violations that were particularly ugly looking
when browsing through.
Split the matching and non-matching cases out into their own functions to
reduce future complexity. As the name implies, procmatches will eventually
process more than one match itself in the future.
The pwd.db and spwd.db files store the change and expire dates as
unsigned 32-bit ints, which overflow in 2106. Reject larger values for
now, until the introduction of a v5 password database.
i386 has 32-bit time_t and so dates beyond y2038 are already rejected by
mktime.

- Move all of the code responsible for transmitting log messages into a
separate function, fprintlog_write().
- Instead of manually modifying a list of iovecs, add a structure
iovlist with some helper functions.
- Alter the F_FORW (UDP message forwarding) case to also use iovecs like
the other cases. Use sendmsg() instead of sendto().
- In the case of F_FORW, truncate the message to a size dependent on the
address family (AF_INET, AF_INET6), as proposed by RFC 5426.
- Move all traditional message formatting into fprintlog_bsd(). Get rid
of some of the string copying and snprintf()'ing. Simply emit more
iovecs to get the job done.
- Increase ttymsg()'s limit of 7 iovecs to 32. Add a definition for this
limit, so it can be reused by iovlist.
- Add fprintlog_rfc5424() to emit RFC 5424 formatted log entries.
- Add a "-O" command line option to enable RFC 5424 formatting. It would
have been nicer if we supported "-o rfc5424", just like on NetBSD.
Unfortunately, the "-o" flag is already used for a different purpose
on FreeBSD.
- Don't truncate hostnames in the RFC 5424 case, as suggested by that
specific RFC.
For people interested in using this, this feature can be enabled by
adding the following line to /etc/rc.conf:
syslogd_flags="-s -O rfc5424"

- Passing "-" to -o will now cause output to go to stdout

To create hybrid boot media we want to specify a partition at a known location.
This extends the syntax of size partitions to include an optional offset that
can be absolute or relative. It also introduces validation to make sure that
this hasn't resulted in overlapping partitions. I haven't added this to the
file and process partition specifications yet but the mechanics are designed
such that if someone comes up with a good way of specifying the offset it
will be fairly easy to add in.

The TCP Blackbox Recorder allows you to capture events on a TCP connection
in a ring buffer. It stores metadata with the event. It optionally stores
the TCP header associated with an event (if the event is associated with a
packet) and also optionally stores information on the sockets.
It supports setting a log ID on a TCP connection and using this to correlate
multiple connections that share a common log ID.
You can log connections in different modes. If you are doing a coordinated
test with a particular connection, you may tell the system to put it in
mode 4 (continuous dump). Or, if you just want to monitor for errors, you
can put it in mode 1 (ring buffer) and dump all the ring buffers associated
with the connection ID when we receive an error signal for that connection
ID. You can set a default mode that will be applied to a particular ratio
of incoming connections. You can also manually set a mode using a socket
option.
This commit includes only basic probes. rrs@ has added quite an abundance
of probes in his TCP development work. He plans to commit those soon.
There are user-space programs which we plan to commit as ports. These read
the data from the log device and output pcapng files, and then let you
analyze the data (and metadata) in the pcapng files.

The general idea here is to provide userspace programs with well-defined
sources of entropy, in a fashion that doesn't require opening a new file
descriptor (ulimits) or accessing paths (/dev/urandom may be restricted
by chroot or capsicum).
getrandom(2) is the more general API, and comes from the Linux world.
Since our urandom and random devices are identical, the GRND_RANDOM flag
is ignored.
getentropy(3) is added as a compatibility shim for the OpenBSD API.
truss(1) support is included.
Tests for both system calls are provided. Coverage is believed to be at
least as comprehensive as LTP getrandom(2) test coverage. Additionally,
instructions for running the LTP tests directly against FreeBSD are provided
