e505460228 Import the netdump client code.
This is a component of a system which lets the kernel dump core to
a remote host after a panic, rather than to a local storage device.
The server component is available in the ports tree. netdump is
particularly useful on diskless systems.

The netdump(4) man page contains some details describing the protocol.
Support for configuring netdump will be added to dumpon(8) in a future
commit. To use netdump, the kernel must have been compiled with the
NETDUMP option.

The initial revision of netdump was written by Darrell Anderson and
was integrated into Sandvine's OS, from which this version was derived.

44af5666d9 bthidd(8): Add evdev protocol support for bluetooth keyboards and mouses
User-visible changes:

"-u" is added to to list of command line options supported by bthidd.
Use it to enable evdev support. uinput and evdev modules should be
kld-loaded or compiled into the kernel in that case.

bthidd_evdev_support rc.conf variable is added to control enabling of
evdev support in bthidd startup script. Possible values are: "YES", "NO",
"AUTO"(default). Setting bthidd_evdev_support to "AUTO" inserts "-u" option
if kernel is compiled with EVDEV_SUPPORT option enabled.

Support for consumer HID usage page keyboard events is implemented. Most of
them are available only through evdev protocol.

kern.evdev.rcpt_mask sysctl is checked, so "sysctl kern.evdev.rcpt_mask=12"
should be executed if EVDEV_SUPPORT is compiled into kernel.

It is recommended to regenerate bthidd.conf entries with bthidcontrol(8)
"Query" command to set user-friendly names of bluetooth devices.

addc1b6ce4 Fix ddb rc script
r288291 added a call to limits(1), which isn't available before partitions
are mounted. This broke the ddb rc script, which does not provide its own
start_cmd.

Alleviate the situation here by providing a start_cmd. We still have other
problems with diskless setups that need to be considered, but this is a
start.

8ce99bb405 Properly do a deep copy of the ioctls capability array for fget_cap().
fget_cap() tries to do a cheaper snapshot of a file descriptor without
holding the file descriptor lock.  This snapshot does not do a deep
copy of the ioctls capability array, but instead uses a different
return value to inform the caller to retry the copy with the lock
held.  However, filecaps_copy() was returning 1 to indicate that a
retry was required, and fget_cap() was checking for 0 (actually
'!filecaps_copy()').  As a result, fget_cap() did not do a deep copy
of the ioctls array and just reused the original pointer.  This cause
multiple file descriptor entries to think they owned the same pointer
and eventually resulted in duplicate frees.

The only code path that I'm aware of that triggers this is to create a
listen socket that has a restricted list of ioctls and then call
accept() which calls fget_cap() with a valid filecaps structure from
getsock_cap().

To fix, change the return value of filecaps_copy() to return true if
it succeeds in copying the caps and false if it fails because the lock
is required.  I find this more intuitive than fixing the caller in
this case.  While here, change the return type from 'int' to 'bool'.

Finally, make filecaps_copy() more robust in the failure case by not
copying any of the source filecaps structure over.  This avoids the
possibility of leaking a pointer into a structure if a similar future
caller doesn't properly handle the return value from filecaps_copy()
at the expense of one more branch.

I also added a test case that panics before this change and now passes.

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.

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.

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.

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.
