The test code prior to r311893 loaded geom_gate at test start if necessary and
skipped the tests if it couldn't be loaded.
The ATF-ifcation of this test done in r311893 unfortunately dropped this
functionality.
This change restores the geom_gate module load and skips the test(s) if unavailable
in an ATF-like way.

- 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 issue is not seen on Jenkins because

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.

- Refactor kld loading/unloading logic:
-- Use a loop instead of an unrolled one.
-- Check for the module being loaded before trying to load it, to reduce
noise when loading modules that are already loaded.
-- Don't mute stderr from kldload -- it could be potentially useful to
the tester.
-- In the event that the test script was terminated early, it would leave
the modules still attached to the system (which is undesirable).
Always unload the modules at test end with EXIT/SIGINT/SIGTERM so the
system is returned to its former operating state as best possible.
Unload the modules in reverse order, in part for consistency and/or

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.

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.

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

File and disk-backed I/O requests store counts of read/written disk
blocks in each AIO job so that they can be charged to the thread that
completes an AIO request via aio_return() or aio_waitcomplete(). This
change extends AIO jobs to store counts of received/sent messages and
updates socket backends to set these counts accordingly. Note that
the socket backends are careful to only charge a single messages for
each AIO request even though a single request on a blocking socket might
invoke sosend or soreceive multiple times. This is to mimic the
resource accounting of synchronous read/write.
Adjust the UNIX socketpair AIO test to verify that the message resource
usage counts update accordingly for aio_read and aio_write.

Always create loopback routes on every fib, for both IPv4 and IPv6
etc/rc.d/routing
Create loopback IPv4 and IPv6 routes on every fib at boot. Revert
278302; now that all FIBs have IPv6 loopback routes, the
"route add -reject" commands won't fail.
tests/etc/rc.d/routing_test.sh
Greatly simplify static_ipv6_loopback_route_for_each_fib. It was
written under the assumption that loopback routes would be added to
a given fib by the kernel as soon as an interface is configured on
that fib. However, the logic can be much simpler now that we simply
add loopback routes to all fibs at boot. This also removes the need
to run the test as root, removes the restriction that
net.add_addr_allfibs=0, and removes the need to configure fibs in
kyua.conf.
Also, add a test case for IPv4 loopback routes

After the previous changes to fix requests on blocking sockets to complete
across multiple operations, an edge case exists where a request can be
cancelled after it has partially completed. POSIX doesn't appear to
dictate exactly how to handle this case, but in general I feel that
aio_cancel() should arrange to cancel any request it can, but that any
partially completed requests should return a partial completion rather
than ECANCELED. To that end, fix the socket AIO cancellation routine to
return a short read/write if a partially completed request is cancelled
rather than ECANCELED.

Always requeue an AIO job at the head of the socket buffer's queue if
sosend() or soreceive() returns EWOULDBLOCK on a blocking socket.
Previously, requests were only requeued if they returned EWOULDBLOCK
and completed no data. Now after a partial completion on a blocking
socket the request is queued and the remaining request is retried when
the socket is ready. This allows writes larger than the currently
available space on a blocking socket to fully complete. Reads on a
blocking socket that satifsy the low watermark can still return a short
read (same as read()).
In order to track previously completed data, the internal 'status'
field of the AIO job is used to store the amount of previously
computed data.
Non-blocking sockets continue to return short completions for both
reads and writes.
Add a test for a "large" AIO write on a blocking socket that writes
twice the socket buffer size to a UNIX domain socket.

Summary of changes:
- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
namespacing is kept with FILES appropriately, and that this shouldn't need
to be repeated if the namespace changes -- only the definition of PACKAGE
needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
`tests`. In the event we get to the point where things can be split up
enough in the base system, it would make more sense to group the tests
with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)
Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.

Two new functions are provided, bit_ffs_at() and bit_ffc_at(), which allow
for efficient searching of set or cleared bits starting from any bit offset
within the bit string.
Performance is improved by operating on longs instead of bytes and using
ffsl() for searches within a long. ffsl() is a compiler builtin in both
clang and gcc for most architectures, converting what was a brute force
while loop search into a couple of instructions.
All of the bitstring(3) API continues to be contained in the header file.
Some of the functions are large enough that perhaps they should be uninlined
and moved to a library, but that is beyond the scope of this commit.
sys/sys/bitstring.h:
Convert the majority of the existing bit string implementation from
macros to inline functions.
Properly protect the implementation from inadvertant macro expansion
when included in a user's program by prefixing all private
macros/functions and local variables with '_'.
Add bit_ffs_at() and bit_ffc_at(). Implement bit_ffs() and
bit_ffc() in terms of their "at" counterparts.
Provide a kernel implementation of bit_alloc(), making the full API
usable in the kernel.
Improve code documenation.
share/man/man3/bitstring.3:
Add pre-exisiting API bit_ffc() to the synopsis.
Document new APIs.
Document the initialization state of the bit strings
allocated/declared by bit_alloc() and bit_decl().
Correct documentation for bitstr_size(). The original code comments
indicate the size is in bytes, not "elements of bitstr_t". The new
implementation follows this lead. Only hastd assumed "elements"
rather than bytes and it has been corrected.

sbin/hastd/activemap.c:
Correct usage of bitstr_size().
sys/dev/xen/blkback/blkback.c
Use new bit_alloc.
sys/kern/subr_unit.c:
Remove hard-coded assumption that sizeof(bitstr_t) is 1. Get rid of
unrb.busy, which caches the number of bits set in unrb.map. When
INVARIANTS are disabled, nothing needs to know that information.
callapse_unr can be adapted to use bit_ffs and bit_ffc instead.
Eliminating unrb.busy saves memory, simplifies the code, and
provides a slight speedup when INVARIANTS are disabled.

Use the new kernel implementation of bit-alloc, instead of hacking
the old libc-dependent macro.

before).

Cosmetic changes:
- Replace a `(void*)0` with NULL.
- Do some minor whitespace clean up.
- Remove an unnecessary cast to mmap.
- Make all munmap calls use ATF_REQUIRE_MSG instead of using the:

The older AIO code awakened all pending AIO requests on a socket
when any data arrived. This could result in AIO daemons blocking on
an empty socket buffer. These requests could not be cancelled
which led to a deadlock during process exit. This test reproduces
this case. The newer AIO code is able to cancel the pending AIO
request correctly.
