In case of health counter fails to increment it indicates a bad device health.
In case when the syndrome indicated by firmware is 0x0, this indicates that
firmware is unable to respond to initialization segment reads.
Add proper print in this case.

MPFS is a logical switch in the Mellanox device which forward packets
based on a hardware driven L2 address table, to one or more physical-
or virtual- functions. The physical- or virtual- function is required
to tell the MPFS by using the MPFS firmware commands, which unicast
MAC addresses it is requesting from the physical port's traffic.
Broadcast and multicast traffic however, is copied to all listening
physical- and virtual- functions and does not need a rule in the MPFS
switching table.

When the software send queue gets filled up, callbacks to
if_transmit will stop. Make sure the transmit callback
routine checks the send queue and outputs any remaining
mbufs. Else the remaining mbufs may simply sit in the
output queue blocking the transmit path.

The regexec function is declared as taking an array of regmatch_t

correct, triggers a Coverity warning. Convert the singleton into
an array of one to silence the warning.

kern_shm_open2(), since conception, completely fails to pass the mode along
to kern_shm_open(). This breaks most uses of it.
Add tests alongside this that actually check the mode of the returned

As is the current trend; while these files are manually curated, they are

This is a simple utility to hash all trusted on the system into

This setup will add the trusted certificates from the Mozilla NSS bundle
to base.
This commit includes:
- CAROOT option to opt out of installation of certs
- mtree amendments for final destinations
- infrastructure to fetch/update certs, along with instructions
A follow-up commit will add a certctl(8) utility to give the user control
over trust specifics. Another follow-up commit will actually commit the
initial result of updatecerts.

Before my ZIL space optimization few years ago 128KB writes were logged
as two 64KB+ records in two 128KB log blocks. After that change it became
~124KB+/4KB+ in two 128KB log blocks to free space in the second block
for another record. Unfortunately in case of 128KB only writes, when space
in the second block remained unused, that change increased write latency by
imbalancing checksum computation time between parallel threads.
This change introduces new 68KB log block size, used for both writes below
67KB and 128KB-sharp writes. Writes of 68-127KB are still using one 128KB
block to not increase processing overhead. Writes above 131KB are still
using full 128KB blocks, since possible saving there is small. Mixed loads
will likely also fall back to previous 128KB, since code uses maximum of
the last 10 requested block sizes.
On a simple 128KB write test with queue depth of 1 this change demonstrates
~15-20% performance improvement.

This adds 8 and 16 bit versions of the cmpset and fcmpset functions. Macros
are used to generate all the flavors from the same set of instructions; the
macro expansion handles the couple minor differences between each size
variation (generating ldrexb/ldrexh/ldrex for 8/16/32, etc).
In addition to handling new sizes, the instruction sequences used for cmpset
and fcmpset are rewritten to be a bit shorter/faster, and the new sequence
will not return false when *dst==*old but the store-exclusive fails because
of concurrent writers. Instead, it just loops like ldrex/strex sequences
normally do until it gets a non-conflicted store. The manpage allows LL/SC
architectures to bogusly return false, but there's no reason to actually do
so, at least on arm.

This avoids PATH conflicts with a real httpd, as a user will likely almost
always prefer the more fully-featured httpd. This also lines up with the
historical name of the program.
work. More precisely, it doesn't set ATTR_AP(ATTR_AP_USER) in the page
table entry, so any attempt to read from the mapped page by user space
generates a page fault. This problem has gone unnoticed because the page
fault handler, vm_fault(), will ultimately call pmap_enter(), which
replaces the non-working page table entry with one that has
ATTR_AP(ATTR_AP_USER) set.
This change reduces the number of page faults during a "buildworld" by
about 19.4%.
