d7f27102b5 armv8 has support for optional CRC32C instructions. This patch checks if they are
available and if that is true make use of them.
Thank you very much to Andrew Turner for providing help and review the patch!

5a33a2afb3 Fix back-to-back runs of sys/netinet/fibs_test;slaac_on_nondefault_fib6
This test was failing if run twice because rtadvd takes too long to die.
The rtadvd process from the first run was still running when the
second run created its interfaces.  The solution is to use SIGKILL during
the cleanup instead of SIGTERM so rtadvd will die faster.

While I'm here, randomize the addresses used for the test, which makes bugs
like this easier to spot, and fix the cleanup order to be the opposite of
the setup order

bc2be1d35b ptrace_test: eliminate assumption about thread scheduling
A couple of the ptrace tests make assumptions about which thread in a
multithreaded process will run after a halt. This makes the tests less
portable across branches, and susceptible to future breakage. Instead,
twiddle thread scheduling and priorities to match the tests'
expectation.

	In in6_selectsrc, use the caller's fib instead of the default fib.
	In in6_selectsrc_socket, remove a superfluous check.

	messages.  In nd6_is_new_addr_neighbor, check all FIBs when trying
	to determine whether an address is a neighbor.  Also, simplify the
	code for point to point interfaces.

	different FIBs.  If rt_add_addr_allfibs=0, only install or delete
	the prefix route on the interface fib.

b4d3325975 Don't clear p_ptevents on normal SIGKILL delivery
The ptrace() user has the option of discarding the signal. In such a
case, p_ptevents should not be modified. If the ptrace() user decides to
send a SIGKILL, ptevents will be cleared in ptracestop(). procfs events
do not have the capability to discard the signal, so continue to clear
the mask in that case.

b38bd91f4f don't stop in issignal() if P_SINGLE_EXIT is set
Suppose a traced process is stopped in ptracestop() due to receipt of a
SIGSTOP signal, and is awaiting orders from the tracing process on how
to handle the signal. Before sending any such orders, the tracing
process exits. This should kill the traced process. But suppose a second
thread handles the SIGKILL and proceeds to exit1(), calling
thread_single(). The first thread will now awaken and will have a chance
to check once more if it should go to sleep due to the SIGSTOP.  It must
not sleep after P_SINGLE_EXIT has been set; this would prevent the
SIGKILL from taking effect, leaving a stopped orphan behind after the
tracing process dies.

Also add new tests for this condition.

82a4538f31 Defer ptracestop() signals that cannot be delivered immediately
When a thread is stopped in ptracestop(), the ptrace(2) user may request
a signal be delivered upon resumption of the thread. Heretofore, those signals
were discarded unless ptracestop()'s caller was issignal(). Fix this by
modifying ptracestop() to queue up signals requested by the ptrace user that
will be delivered when possible. Take special care when the signal is SIGKILL
(usually generated from a PT_KILL request); no new stop events should be
triggered after a PT_KILL.

Add a number of tests for the new functionality. Several tests were authored
by jhb.

d893c36a35 A forced commit to note other portion of the Makefile change accidentally
committed in r313972

The code committed in r313962 implicitly relies on python 2.x to generate
testvect.h . There are a handful of issues with this approach:

- python is not an explicit build dependency for FreeBSD
- python 2.x is deprecated and will be removed sometime in the future
  (potentially before 11.x's EOL), and the script does not function with
  python 3.5 (it uses deprecated idioms and incompatible function calls).
- python(1) (by default) lives in /usr/local/bin (${LOCALBASE}/bin) and
  gentestvect.py is a dependency of testvect.h (prior to r313972) which
  means that if the mtime of the generator script was newer than the
  mtime of the test vector, it could cause a spurious build failure in
  build time or at install time.

A better solution using C/C++ should be devised.

85c15ab853 improve PBKDF2 performance
The PBKDF2 in sys/geom/eli/pkcs5v2.c is around half the speed it could be

GELI's PBKDF2 uses a simple benchmark to determine a number of iterations
that will takes approximately 2 seconds. The security provided is actually
half what is expected, because an attacker could use the optimized
algorithm to brute force the key in half the expected time.

With this change, all newly generated GELI keys will be approximately 2x
as strong. Previously generated keys will talk half as long to calculate,
resulting in faster mounting of encrypted volumes. Users may choose to
rekey, to generate a new key with the larger default number of iterations
using the geli(8) setkey command.

Security of existing data is not compromised, as ~1 second per brute force
attempt is still a very high threshold.

b42fffb4ef Replace for/retry loops with "wait_for_ggate_device" calls and check
results of commands

As noted in r313008, the underlying issue was that geom_gate device
creation wasn't created at ggatel command completion, but some short
time after. ggatec(8) employs similar logic when creating geom_gate(4)
devices.

Switch from retry loops (after the ggatec/dd write calls) to
wait_for_ggate_device function calls after calling ggatec(8) instead
to detect the presence of the /dev/ggate* device, as this function is
sufficient for determining whether or not the character device is ready
for testing

While here, use atf_check consistently with all dd calls to ensure that
data output is as expected.

The test assumed that `ggatel create` created a device on completion, but that's
incorrect. This squashes the race by waiting for the device to appear, as
`ggatel create` daemonizes before issuing an ioctl to geom_gate(4) if not called
with `-v`.

6be2ff7d3e calculate_crc32c: Add SSE4.2 implementation on x86
Derived from an implementation by Mark Adler.

The fast loop performs three simultaneous CRCs over subsets of the data
before composing them.  This takes advantage of certain properties of
the CRC32 implementation in Intel hardware.  (The CRC instruction takes 1
cycle but has 2-3 cycles of latency.)

The CRC32 instruction does not manipulate FPU state.

i386 does not have the crc32q instruction, so avoid it there.  Otherwise
the implementation is identical to amd64.

Add basic userland tests to verify correctness on a variety of inputs.
