Instead of running tests one-by-one with the shell wrapper we now run
the full gtest testsuite twice (once as root, once as non root). This
significantly speeds up running tests despite running them twice.
This change also passes the missing -u flag to capsicum-test that caused
test failures (https://bugs.freebsd.org/250178)
Previously, running the testsuite with the wrapper script took ~3s per
test on aarch64 QEMU, i.e. a total of almost 5 minutes.
Now it takes 6 seconds to run all tests twice.
Before:
root@freebsd-aarch64:/usr/tests/sys/capsicum # /usr/bin/time kyua test functional
94/96 passed (2 failed)
309.97 real 58.46 user 244.31 sys
After:
root@freebsd-aarch64:/usr/tests/sys/capsicum # /usr/bin/time kyua test functional
functional:test_root -> passed [2.659s]
functional:test_unprivileged -> passed [2.391s]
2/2 passed (0 failed)
5.48 real 1.06 user 2.52 sys
This overhead is caused by kyua + atf-sh spawning lots of additional
processes and can be avoided by just running the googletest test binary.

This includes various fixes that I submitted recently such as updating the
pdkill() tests for the actual implemented behaviour
(https://github.com/google/capsicum-test/pull/53) and lots of changes to
avoid calling sleep() and replacing it with reliable synchronization
(pull requests 49,51,52,53,54). This should make the testsuite more reliable
when running on Jenkins. Additionally, process status is now retrieved using
libprocstat instead of running `ps` and parsing the output
(https://github.com/google/capsicum-test/pull/50). This fixes one previously
failing test and speeds up execution.
Overall, this update reduces the total runtime from ~60s to about 4-5 seconds.
When searching for runs to reclaim, we need to ensure that the entire
run will be added to the buddy allocator as a single unit. Otherwise,
it will not be visible to vm_phys_alloc_contig() as it is currently
implemented. This is a problem for allocation requests that are not a
power of 2 in size, as with 9KB jumbo mbuf clusters.

There are three issues with change that stopped truncating ea area before
write, and resulted in possible zero tail in the ea area:
- Truncate to zero checked i_ea_len after the reference was dropped,
making the last drop effectively truncate to zero length always.
- Loop to fill uio for zeroing specified too large length, that triggered
assert in normal situation.
- Integrity check could trip over the tail, instead we must allow
partial header or header with zero length, and clamp ea image in
memory at it.

During a recent virtual NFSv4 testing event, a bug in the FreeBSD client
was detected when doing a File Layout pNFS DS I/O operation.
The size of the I/O operation was smaller than expected.
The I/O size is specified as a stripe unit size in bits 6->31 of nflh_util
in the layout. I had misinterpreted RFC5661 and had shifted the value
right by 6 bits. The correct interpretation is to use the value as
presented (it is always an exact multiple of 64), clearing bits 0->5.
This patch fixes this.
Without the patch, I/O through the DSs work, but the I/O size is 1/64th
of what is optimal.

It appears that the stackframe layout can be slightly different depending on

The default behavior for attaching processes to jails is that the jail's
cpuset augments the attaching processes, so that it cannot be used to
escalate a user's ability to take advantage of more CPUs than the
administrator wanted them to.
This is problematic when root needs to manage jails that have disjoint
sets with whatever process is attaching, as this would otherwise result
in a deadlock. Therefore, if we did not have an appropriate common
subset of cpus/domains for our new policy, we now allow the process to
simply take on the jail set *if* it has the privilege to widen its mask
anyways.
With the new logic, root can still usefully cpuset a process that
attaches to a jail with the desire of maintaining the set it was given
pre-attachment while still retaining the ability to manage child jails
without jumping through hoops.
A test has been added to demonstrate the issue; cpuset of a process
down to just the first CPU and attempting to attach to a jail without
access to any of the same CPUs previously resulted in EDEADLK and now
results in taking on the jail's mask for privileged users.

The main issue is that debug exceptions must to be disabled for the
entire duration that SS bit in MDSCR_EL1 is set. Otherwise, a
single-step exception will be generated immediately. This can occur
before returning from the debugger (when MDSCR is written to) or before
re-entering it after the single-step (when debug exceptions are unmasked
in the exception handler).
Solve this by delaying the unmask to C code for EL1, and avoid unmasking
at all while handling debug exceptions, thus avoiding any recursive
debug traps.
