When multiple threads wish to report a tracing event to a debugger,
both threads call ptracestop() and one thread will win the race to be
the reporting thread (p->p_xthread). The debugger uses PT_LWPINFO
with the process ID to determine which thread / LWP is reporting an
event and the details of that event. This event is cleared as a side
effect of the subsequent ptrace event that resumed the process
(PT_CONTINUE, PT_STEP, etc.). However, ptrace() was clearing the
event identified by the LWP ID passed to the resume request even if
that wasn't the 'p_xthread'. This could result in clearing an event
that had not yet been observed by the debugger and leaving the
existing event for 'p_thread' pending so that it was reported a second
time.
Specifically, if the debugger stopped due to a software breakpoint in
one thread, but then switched to another thread that was used to
resume (e.g. if the user switched to a different thread and issued a
step), the resume request (PT_STEP) cleared a pending event (if any)
for the thread being stepped. However, the process immediately
stopped and the first thread reported it's breakpoint event a second
time. The debugger decremented the PC for "both" breakpoint events
which resulted in the PC now pointing into the middle of an
instruction (on x86) and a SIGILL fault when the process was resumed a
second time.
To fix, always clear the pending event for 'p_xthread' when resuming a
process. ptrace() still honors the requested LWP ID when enabling
single-stepping (PT_STEP) or setting a different PC (PT_CONTINUE).

Test fragmentation handling (i.e. scrub fragment reassemble) code for
IPv6.
Two simple tests: Ping a host (jail) and test forwarding of fragmented
packets.
When cleaning up we must destroy the jails before we destroy the interfaces.
Otherwise we might try to destroy interfaces that belong to a jail, which won't
work and fail to completely clean up.
Pass/block packets in the forwarding path with pf.
Introduce the pft_set_rules() helper function, because we need to
remember to flush states between individual tests. If not we can get
packets passing despite rules blocking them because they match states
created in a previous test.
Extend pft_ping.py to be able to send IPv6 echo requests.
^/head@r323923 changed when MODIFIED is printed at exit. It's better to follow the
documented way of determining whether or not a filesystem is clean per fsck_ffs, i.e.,
ensure that the exit code is either 0 or 7.
The pass/fail determination is brittle prior to this commit, and ^/head@r323923 made
the issue apparent -- thus this needs to be fixed independent of ^/head@r323923.

If VIMAGE is present we can start jails with their own pf instance. This
makes it fairly easy to run tests.
For example, this basic test verifies that drop/pass and icmp
classification works. It's a basic sanity test for pf, and hopefully an
example on how to write more pf tests.
The tests are skipped if VIMAGE is not enabled.
This work is inspired by the GSoC work of Panagiotes Mousikides.

Some x86 class CPUs have accelerated intrinsics for SHA1 and SHA256.
Provide this functionality on CPUs that support it.
This implements CRYPTO_SHA1, CRYPTO_SHA1_HMAC, and CRYPTO_SHA2_256_HMAC.
Correctness: The cryptotest.py suite in tests/sys/opencrypto has been
enhanced to verify SHA1 and SHA256 HMAC using standard NIST test vectors.
The test passes on this driver. Additionally, jhb's cryptocheck tool has
been used to compare various random inputs against OpenSSL. This test also
passes.
Rough performance averages on AMD Ryzen 1950X (4kB buffer):
aesni: SHA1: ~8300 Mb/s SHA256: ~8000 Mb/s
cryptosoft: ~1800 Mb/s SHA256: ~1800 Mb/s
So ~4.4-4.6x speedup depending on algorithm choice. This is consistent with
the results the Linux folks saw for 4kB buffers.
The driver borrows SHA update code from sys/crypto sha1 and sha256. The
intrinsic step function comes from Intel under a 3-clause BSDL.[0] The
intel_sha_extensions_sha<foo>_intrinsic.c files were renamed and lightly
modified (added const, resolved a warning or two; included the sha_sse
header to declare the functions).

- Import print_function from __future__ and use print(..) instead of `print ..`.
- Use repr instead of backticks when the object needs to be dumped, unless
print(..) can do it lazily. Use str instead of backticks as appropriate
for simplification reasons.
This doesn't fully convert these modules over py3k. It just gets over some of
the trivial compatibility hurdles.

Previously, this test was entirely a no-op as no vector in the NIST-KAT file
has a precisely 20-byte key.
Additionally, not every vector in the file is SHA1. The length field
determines the hash under test, and is now decoded correctly.
Finally, due to a limitation I didn't feel like fixing in cryptodev.py, MACs
are truncated to 16 bytes in this test.
With this change and the uncommitted D12437 (to allow key sizes other than
those used in IPSec), the SHA tests in cryptotest.py actually test something
and e.g. at least cryptosoft passes the test.

tests/... changes:
- Add appropriate support Makefile.inc's to set HAS_TESTS in a minimal manner,

- Use "atf_check -x 'cmd1 | cmd2'" instead of "cmd1 | atf_check cmd2". The
two forms are idiomatically similar, but subtly different in the sense of
what program invokes the other, and there could be unwanted side effects
of the latter idiom dealing with forking, pipes, etc.
- Remove chmod and instead source coredump_phnum_restore_state.sh directly.
This avoids the need to check the result of the chmod call.
- Fix indentation in an if-block (4 column space indentation -> hard tab).
The testcase no longer fails on ^/head because readelf has established parity
with binutils' copy of readelf.

This change implements NOTE_ABSTIME flag for EVFILT_TIMER, which
specifies that the data field contains absolute time to fire the
event.
To make this useful, data member of the struct kevent must be extended
to 64bit. Using the opportunity, I also added ext members. This
changes struct kevent almost to Apple struct kevent64, except I did
not changed type of ident and udata, the later would cause serious API
incompatibilities.
The type of ident was kept uintptr_t since EVFILT_AIO returns a
pointer in this field, and e.g. CHERI is sensitive to the type
(discussed with brooks, jhb).
Unlike Apple kevent64, symbol versioning allows us to claim ABI
compatibility and still name the new syscall kevent(2). Compat shims
are provided for both host native and compat32.
