Empty or FS_UNUSED partitions don't intrude into the OpenBSD area
of a disk and therefore should not disable partition resizing.

This refactoring is another step to make standalone socket buffers
locking. sblock() uses M_WAITOK and M_NOWAIT flags passed as the third
argument together with the SB_NOINTR flag on the `sb_flags' to control
sleep behaviour. To perform uninterruptible acquisition, SB_NOINTR flag
should be set before sblock() call. `sb_flags' modification requires to
hold solock() around sblock()/sbunlock() that makes standalone call
impossible.
Also `sb_flags' modifications outside sblock()/sbunlock() makes
uninterruptible acquisition code huge enough. This time only sorflush()
does this (and forgets to restore SB_NOINTR flag, so shutdown(SHUT_RDWR)
call permanently modifies socket locking behaviour) and this looks not
the big problem. But with the standalone socket buffer locking it will
be many such places, so this huge construction is unwanted.
Introduce new SBL_NOINTR flag passed as third sblock() argument. The
sblock() acquisition will be uninterruptible when existing SB_NOINTR
flag is set on `sb_flags' or SBL_NOINTR was passed.
The M_WAITOK and M_NOWAIT flags belongs to malloc(9). It has no M_NOINTR
flag and there is no reason to introduce it. So for consistency reasons
introduce new SBL_WAIT and use it together with SBL_NOINTR instead of
M_WAITOK and M_NOINTR respectively.

ci_mds_tmp needs to be 32-byte aligned, otherwise we trip a CTASSERT
in amd64/cpu.c and break kernel compilation. However, ci_mds_tmp's
32-byte alignment is at risk: the size of schedstate_percpu is about
to change.
Move ci_curproc and ci_schedstate up just after ci_mds_buf. This puts
ci_mds_tmp at page offset 64 with no structs ahead of it in cpu_info.
With this arrangement it should remain 32-byte aligned without much
effort.

The caller can provide an r which will be added to the ECDSA_SIG unchecked.
This can happen via ECDSA_{,do_}sign_ex() or ECDSA_sign_setup() or else via
a custom sign_sig() handler. Therefore add a check that it is in the bounds
required.
Since k was long thrown away, there's no way to check kinv, so it needs to
be trusted. Misdesigned APIs that will output garbage everywhere...

Use variable names that correspond more closely to the standard. Use an
additional variable for s^-1 for readability. Annotate the code with
the corresponding steps from FIPS 186-5.

handler, allocate it ourselves. The firmware doesn't seem to mind
that it's us doing the allocation. This fixes a splassert, because
the code that retrieves the item reaches through the shared memory
driver, which acquires the hardware mutex, which in turn mallocs.

pf_open_trans() can issue for each clone of /dev/pf
to 512. The pf_open_trans() is currently being used
by DIOCGETRULES ioctl(2). The limit avoids processes
to consume all kernel memory by asking DIOCGETRULES
for more tickets. If DIOCGETRULES hits the limit, then
the application will see EBUSY error.
This diff was fine tuned with feedback from cluadio@,
deraadt@ and kn@.

periodically read rules from pf(4) to consume all kernel
memory. The bug has been discovered and root caused by florian@.
In this particular case it was snmpd(8) what ate all kernel
memory.
This commit introduces DIOCXEND to pf(4) so applications such
as snmpd(8) and systat(1) to close ticket/transaction when
they are done with fetching the rules. This change also
updates snmpd(8) and systat(1) to use newly introduced
DIOCXEND ioctl(2).

with Makefile. To create the test environment, use the
Makefile.bsd-wrapper in /usr/src/gnu/usr.bin/perl and build Perl
there if it does not exist. This allows to test Perl easily and
in a consistent manner. Do not link tests to regress tree due to
this reach around and the combination of build and test.
This pushes a few variables no longer needed in ossl_ecdsa_sign_sig() into
ecdsa_compute_s() separating API logic and pure computation a bit more.

kstats. Some of the hardware counters are already used in
bge_stats_update_regs() to update interface counters and work around
hardware bugs, and all counters reset on read, so to keep things simple
the work is split between that function and bge_kstat_read(), which
reads the rest of the counters.
tested by bluhm@ on BCM5720 (with counters) and BCM5704 (without), and
by me on BCM5720 A0 (with counters and hardware bugs)

Make it take an EC_KEY instead of a group order in preparation for further
cleanup. Rename m into e to match the standard better. Also buy some vowels
