rtsold: Fix validation of RDNSS options
The header specifies the size of the option in multiples of eight bytes.
The option consists of an eight-byte header followed by one or more IPv6
addresses, so the option is invalid if the size is not equal to 1+2n for
some n>0. Check this.
The bug can cause random stack data to be formatted as an IPv6 address
and passed to resolvconf(8), but a host able to trigger the bug may also
specify arbitrary addresses this way.

wpa: import fix for P2P provision discovery processing vulnerability
Latest version available from: https://w1.fi/security/2021-1/
Vulnerability
A vulnerability was discovered in how wpa_supplicant processes P2P
(Wi-Fi Direct) provision discovery requests. Under a corner case
condition, an invalid Provision Discovery Request frame could end up
reaching a state where the oldest peer entry needs to be removed. With
a suitably constructed invalid frame, this could result in use
(read+write) of freed memory. This can result in an attacker within
radio range of the device running P2P discovery being able to cause
unexpected behavior, including termination of the wpa_supplicant process
and potentially code execution.
Vulnerable versions/configurations
wpa_supplicant v1.0-v2.9 with CONFIG_P2P build option enabled
An attacker (or a system controlled by the attacker) needs to be within
radio range of the vulnerable system to send a set of suitably
constructed management frames that trigger the corner case to be reached
in the management of the P2P peer table.

Fix scripted installs on EFI systems after default mounting of the ESP.
Because the ESP mount point (/boot/efi) is in mtree, tar will attempt to
extract a directory at that point post-mount when the system is installed.
Normally, this is fine, since tar can happily set whatever properties it
wants. For FAT32 file systems, however, like the ESP, tar will attempt to
set mtime on the root directory, which FAT does not support, and tar will
interpret this as a fatal error, breaking the install (see
https://github.com/libarchive/libarchive/issues/1516). This issue would
also break scripted installs on bare-metal POWER8, POWER9, and PS3
systems, as well as some ARM systems.
This patch solves the problem in two ways:
- If stdout is a TTY, use the distextract stage instead of tar, as in
interactive installs. distextract solves this problem internally and
provides a nicer UI to boot, but requires a TTY.
- If stdout is not a TTY, use tar but, as a stopgap for 13.0, exclude
boot/efi from tarball extraction and then add it by hand. This is a
hack, and better solutions (as in the libarchive ticket above) will
obsolete it, but it solves the most common case, leaving only
unattended TTY-less installs on a few tier-2 platforms broken.
In addition, fix a bug with fstab generation uncovered once the tar issue
is fixed that umount(8) can depend on the ordering of lines in fstab in a
way that mount(8) does not. The partition editor now writes out fstab in
mount order, making sure umount (run at the end of scripted, but not
interactive, installs) succeeds.

This patch also avoids forking lots of shell processes for each of the 418

Besides making the tests more reliable in CI, a nice side-effect of this

In the CheriBSD CI, we run the testsuite with /tmp as tmpfs. This causes
the extattr audit tests to fail since tmpfs does not (yet) support
extattrs. Skip those tests if the target path is on a file system that
does not support extended file attributes.
While touching these two files also convert the ATF_REQUIRE_EQ(-1, ...)
checks to use ATF_REQURIE_ERRNO().

tests/sys/audit: fix timeout calculation
This changes the behaviour to a 30s total timeout (needed when running
on slow emulated uniprocessor systems) and timing out after 10s without
any input. This also uses timespecsub() instead of ignoring the
nanoseconds field.
After this change the tests runs more reliably on QEMU and time out less
frequently.

Don't include libarchive fuzz tests by default
These tests are basic fuzz tests that permute input to trigger crashes
rather than regression or unit tests. Additionally, some of them take a
rather long time to run and should probably be run on a dedicated fuzzing
job instead. Moreover, these simple tests use rand() instead of a real
fuzzing tool that generates interesting inputs (e.g. LLVM libFuzzer) so are
unlikely to find anything interesting when run in CI.
This allows removing one BROKEN_TESTS case due to timeouts and speeds up
running tests on emulated platforms such as QEMU.
