there's table lookup, fraud, and grand fraud.

NetBSD got activated. NetBSD has an additional change in
their mii.c rev 1.26 which got missed with that merger:
: When probing for a PHY, look at the EXTSTAT bit in the BMSR, as well,
: not just the media mask. This prevents PHYs/TBIs that only support
: Gigabit media from slipping through the cracks.
With this GE only ones like from the SK-9844 are detected again.

This socket option allows processes query a TCP socket for some low
level transmission details, such as the current send, bandwidth, and
congestion windows. Linux provides a 'struct tcpinfo' structure
containing various variables, rather than separate socket options;
this makes the API somewhat fragile as it makes it dificult to add
new entries of interest as requirements and implementation evolve.
As such, I've included a large pad at the end of the structure.
Right now, relatively few of the Linux API fields are filled in, and
some contain no logical equivilent on FreeBSD. I've include __'d
entries in the structure to make it easier to figure ou what is and
isn't omitted. This API/ABI should be considered unstable for the
time being.
Null_open() was only here to handle MNT_NODEV, but since that does
not affect any filesystems anymore, it could only have any effect
if you nullfs mounted a devfs but didn't want devices to show up.
If you need that, there are easier ways.
window was 0 bytes in size. This may have been the cause of unsolved
"connection not closing" reports over the years.
Thanks to Michiel Boland for providing the fix and providing a concise
test program for the problem.

uses the brk_string function to parse the line. That function uses static
storage for both the expanded string and the returned argv[] vector.
The JobParseShell function simply stored away pointers into this static
storage. On the next use of something like ${FOO:O} this storage would
get overwritten with fatal results.
This also allows us to make the shells[] array const bringing us one step
further in making make WARNS=4 ready.
Historically, our contigmalloc1() and contigmalloc2() assumes
that a page in PQ_CACHE can be unconditionally reused by busying
and freeing it. Unfortunatelly, when object happens to be not
NULL, the code will set m->object to NULL and disregard the fact
that the page is actually in the VM page bucket, resulting in
page bucket hash table corruption and finally, a filesystem
corruption, or a 'page not in hash' panic.
This commit has borrowed the idea taken from DragonFlyBSD's fix
to the VM fix by Matthew Dillon[1]. This version of patch will
do the following checks:
- When scanning pages in PQ_CACHE, check hold_count and
skip over pages that are held temporarily.
- For pages in PQ_CACHE and selected as candidate of being
freed, check if it is busy at that time.
Note: It seems that this is might be unrelated to kern/72539.

packet counts by pf(4).
This adds a ``daily_status_security_pfdenied_enable'' variable to
periodic.conf, which defaults to ``YES'' as the matching IPF(W) versions.
The output will look like this (line wrapped):
pf denied packets:
> block drop log on rl0 proto tcp all [ Evaluations: 504986 Packets: 0
Bytes: 0 States: 0 ]
> block drop log on rl0 all [ Evaluations: 18559 Packets: 427 Bytes: 140578

o In looking in the standard, if the cap numbers are 0xffffffff, then acpi
is reporting unknown for that field. Report unknown numbers properly.
o Update the state to reflect charging, discharging and critical.

serial-aware BIOS to set the BIOS to speeds above 9600 and allow boot0 to
just use the existing settings.

my patches for this information. Commit my more complete version.
This version isn't complete yet, since some details aren't handled
