2529f56ed3 Add the "TCP Blackbox Recorder" which we discussed at the developer
summits at BSDCan and BSDCam in 2017.

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.

d5a390e6c7 Move /boot/overlays to /boot/dtb/overlays
The former is fairly vague; these are FDT overlays to be applied to the
running system, so /boot/dtb is a sensible location to put it without
cluttering up /boot/dtb even further if desired.

cc732b9da5 Modify rc.d/fsck to handle new status from fsck/fsck_ffs
r328013 introduced a new error code from fsck_ffs that indicates that
it could not completely fix the file system; this happens when it
prints the message PLEASE RERUN FSCK. However, this status can happen
when fsck is run in "preen" mode and the rc.d/fsck script does not
handle that error code. Modify rc.d/fsck so that if "fsck -p"
("preen") returns the new status code (16) it will run "fsck -y", as
it currently does for a status code of 8 (the "standard error exit").

e808190a59 Add kernel and userspace code to dump the firmware state of supported
ConnectX-4/5 devices in mlx5core.

The dump is obtained by reading a predefined register map from the
non-destructive crspace, accessible by the vendor-specific PCIe
capability (VSC). The dump is stored in preallocated kernel memory and
managed by the mlx5tool(8), which communicates with the driver using a
character device node.

The utility allows to store the dump in format
    <address> <value>
into a file, to reset the dump content, and to manually initiate the
dump.

A call to mlx5_fwdump() should be added at the places where a dump
must be fetched automatically. The most likely place is right before a
firmware reset request.

apply when actually applying the pf.conf file, so we must also take them into

5830b90f4b pf: Do not flush on reload
pfctl only takes the last '-F' argument into account, so this never did what
was intended.

Moreover, there is no reason to flush rules before reloading, because pf keeps
track of the rule which created a given state. That means that existing
connections will keep being processed according to the rule which originally
created them. Simply reloading the (new) rules suffices. The new rules will
apply to new connections.

They open sourced it in OpenSolaris, then HighCloud partially ported it to
FreeBSD, and Spectra Logic finished the port.  We also added many testcases,
fixed many broken ones, and converted them all to the ATF framework.  We've had
help along the way from avg, araujo, smh, and brd.

By default most of the tests are disabled.  Set the disks Kyua variable to

247f52f185 Pass in the NOMATCH event to devmatch
In devd/devmatch.conf, we need to pass the event to the devmatch
serivce. It gets passed to devmatch -p for matching. We always pass
this, unlike hps' original patch, so we kill two birds with one stone
and only match modules to the event passed in.

7e1637e491 If we're passed an argument, then treat it as a single NOMATCH event
to parse rather than searching for all events. Pass with new -p arg to
devmatch. devmatch will use that one event rather than walking the
entire tree.

kldload will stop at the first failure. So we need to loop.  Also,
symbolic links may confused kldload into trying (and failing) to load
multiple modules at once, so guard against that.

b37f6c9805 Add libregex, connect it to the build
libregex is a regex(3) implementation intended to feature GNU extensions and
any other non-POSIX compliant extensions that are deemed worthy.

These extensions are separated out into a separate library for the sake of
not cluttering up libc further with them as well as not deteriorating the
speed (or lack thereof) of the libc implementation.

libregex is implemented as a build of the libc implementation with LIBREGEX
defined to distinguish this from a libc build. The reasons for
implementation like this are two-fold:

1.) Maintenance- This reduces the overhead induced by adding yet another
regex implementation to base.

2.) Ease of use- Flipping on GNU extensions will be as simple as linking
against libregex, and POSIX-compliant compilations can be guaranteed with a
REG_POSIX cflag that should be ignored by libc/regex and disables extensions
in libregex. It is also easier to keep REG_POSIX sane and POSIX pure when
implemented in this fashion.

Tests are added for future functionality, but left disconnected for the time
being while other testing is done.
