Can be used to count the number of hardware threads in the cpu set.
For example:
$ cpuset -g -p $$
pid 2440 mask: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16,
17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34,
35, 36, 37, 38, 39
pid 2440 domain policy: first-touch mask: 0, 1
$ cpuset -g --count -p $$
40
The intent is to replace calls to sysctl hw.ncpu and kern.smp.cpus which
can be found in the tree, which are not adequate given existence of
cpusets.
Right now only -g -p combination is supported to reduce complexity.
As anything else errors out, this can be expanded later as needed.

timeout(1) is used by /etc/rc.d/zfskeys. Unfortunately, having
timeout(1) installed in /usr/bin causes problems when /usr is an
encrypted ZFS partition.
Implementing timeout(1) in sh(1) is not trivial. A more elegant solution
is to move timeout(1) to /bin so that it is available to early services
in the boot process.

* Parse and export newly-added NL_RTA_WEIGHT attribute, providing path
weight for a non-multipath route. This fixes a number of tests in
sys/net/routing which rely on this data.
* Remove handling of NL_RTA_KNH_ID in multipath routes, as it is
not provided.
* Improve kernel/user nexthop index export. As a result,
for multipath routes:
* nhg-kidx attribute represents kernel nhg index (always provided)
* nhg-uidx attribute represents user-provided nhg index (if set)
for non-multipath routes:
* nhop-kidx attribute represents kernel nhop index (always provided)
* nhop-udx attribute represents user-provided nexthop index (if set)
The sources of this program are in contrib/bc, but built using the
Makefiles touched in this commit, which had to be adapted to comply
with changed made to the build system of this software, which is
not used when building in the base system.

Several important base system components are written in C++, and the
WITHOUT_CXX option produced a system that was not fully functional.
Just accept this, and remove the option to build without C++ support.

sysctl() provides a count of number of bytes in the buffer. That is the
actual buffer length. Whereas looking for an interrupt entry with an
empty name could terminate too early, or overflow the end of the buffer.
The overflow will occur if the table of interrupt names is full.

inadvertently using both newline and NUL due to REG_NEWLINE in cflags.
The odds of anyone relying on this bsdgrep-specific bug are quite low,

This subsystem is superseded by modern debugging facilities,
e.g. DTrace probes and TCP black box logging.
We intentionally leave SO_DEBUG in place, as many utilities may
set it on a socket. Also the tcp::debug DTrace probes look at
this flag on a socket.

The previous logic conflated some things... in this block:
- j: input characters rendered so far
- nc: number of characters in the line
- col: columns rendered so far
- hw: column width ((h)ard (w)idth?)
Comparing j to hw or col to nc are naturally wrong, as col and hw are
limits on their respective counters and nc is already brought down to hw
if the input line should be truncated to start with.
Right now, we end up easily truncating lines with tabs in them as we
count each tab for $tabwidth lines in the input line, but we really
should only be accounting for them in the column count. The problem is
most easily demonstrated by the two input files added for the tests,
the two tabbed lines lose at least a word or two even though there's
plenty of space left in the row for each side.

For the TCP protocol inpcb storage specify allocation size that would
provide space to most of the data a TCP connection needs, embedding
into struct tcpcb several structures, that previously were allocated
separately.
The most import one is the inpcb itself. With embedding we can provide
strong guarantee that with a valid TCP inpcb the tcpcb is always valid
and vice versa. Also we reduce number of allocs/frees per connection.
The embedded inpcb is placed in the beginning of the struct tcpcb,
since in_pcballoc() requires that. However, later we may want to move
it around for cache line efficiency, and this can be done with a little
effort. The new intotcpcb() macro is ready for such move.
The congestion algorithm data, the TCP timers and osd(9) data are
also embedded into tcpcb, and temprorary struct tcpcb_mem goes away.
There was no extra allocation here, but we went through extra pointer
every time we accessed this data.
One interesting side effect is that now TCP data is allocated from
SMR-protected zone. Potentially this allows the TCP stacks or other
TCP related modules to utilize that for their own synchronization.
Large part of the change was done with sed script:
s/tp->ccv->/tp->t_ccv./g
s/tp->ccv/\&tp->t_ccv/g
s/tp->cc_algo/tp->t_cc/g
s/tp->t_timers->tt_/tp->tt_/g
s/CCV\(ccv, osd\)/\&CCV(ccv, t_osd)/g
Dependency side effect is that code that needs to know struct tcpcb
should also know struct inpcb, that added several <netinet/in_pcb.h>.

I think this was probably just a typo. initifstat() continues around
a similar loop if the mib data fails to fetch, and fetch_ifstat() was
already using a FOREACH_SAFE loop here so expected to keep going.
Calling clearifstat() from the fetch routine also seems wrong, and the
sort_interface_list() call triggered by the existing needsort = 1 will
itself set needclear to trigger a future clearifstat().

A small reduction in build infrastructure complexity; when we had both
Clang and GCC in the tree it was useful to have both built, and choose
one or the other to install as /usr/bin/cc. Now only Clang is in the
tree, and there is no point in building and installing base Clang but
not providing it as cc (and c++, cpp).
