When `boot_policy` is `RELAXED`, `find_currdev()` tried ZFS pools on every
disk before searching the boot ESP and sibling partitions. Booting install
media from USB could therefore select an installed ZFS root on internal
storage instead of the intended memstick UFS image.
Extract the boot-device partition walk into `try_boot_device_partitions()`
and run it before relaxed foreign-pool probing. The ZFS search order is
preserved; pools on the boot device are tried first, followed by pools on
other devices when `boot_policy` is `RELAXED` and the boot device yields
no bootable root.

Recalculate it to iterate over the right set of processes.
Prevent reaper' struct proc reuse by holding the tree ref on it.
Since our reference is taken under the proctree lock and we know that
the process is reaper, it cannot go away. The process hold count
(p_lock) cannot be used there because p_lock intent is prevent exit, but
reaper owns its reap-children until reaped itself, i.e. even a zombie

AMD does not have a CPUID bit to indicate the lack of K8 PMCs. If all
other PMC features are not present we should test an event selector to
see if it stores and returns a value. If the VM is implemented
correctly, this should result in a #GP on the initial wrmsr_safe. Bhyve
and a few other VMs ignore writes, so I got one step further and test
that it retains the OS and USR bits.
Tested on Zen 5 native and a Zen 5 Bhyve virtual machine. This code
should not run on any recent hardware, except in a VM, as it checks that

We drop the inpcb lock in order to copy in the source list, but this
leaves a window where the multicast filter structure might be freed.
This can be exploited to obtain root privileges.
In the v4 code this race is mitigated by holding the global multicast
lock across the gap.
Restructure the code to copy in filters before doing anything else, so
that there's no need to drop the inpcb lock and reason about the
correctness of doing so. Do the same in the v4 code for consistency.

Normally, data processed on the KTLS receive path is contained in
anonymous mbufs that can be modified in place. Either the data
originates in receive buffers from a NIC driver, or for loopback
connections the data is anonymous-backed mbufs created when writing to
a socket. One potential source of non-anonymous mbufs are mbufs
created by sendfile(2) which borrow the pages of the underlying file,
either via M_EXTPG or EXT_SFBUF that are sent over a loopback
connection. For a well-formed loopback TLS session, the sender should
only use sendfile(2) if KTLS is enabled. If TLS is fully handled in
userspace, the sender must use write(2) or send(2) which allocate
anonymous mbufs. If KTLS transmit is enabled, then sendfile(2) on a
loopback connection will always use crypto via OCF and will allocate
anonymous pages to hold the encrypted data.
However, if sendfile(2) is used to send file-backed data directly over
a loopback connection where KTLS is not enabled on the sender side,
the KTLS receive path can modify the file-backed pages in place
overwriting the file's data. One potential fix would be to replace
non-anonymous mbufs in a received TLS record with anonymous mbufs
(e.g. via m_dup()) before passing the record to OCF. However, there
is no legitimate use case for using sendfile(2) over a loopback TLS
connection without using KTLS on the sender side, so instead simply
fail decryption requests and close the connection if non-anonymous
mbufs are encountered in the RX decryption path.
Add a test for this that verifies that the original data backing the
file descriptor used as the source for sendfile() is unchanged after
being processed.

Shell variable names cannot be safely quoted with shell_escape() —
only alphanumeric characters are valid. Add validation that set-name
only matches [a-zA-Z0-9]+; invalid values are rejected with a
warning and the rename is skipped entirely.
The hostname value was written inside double quotes in
/etc/rc.conf.d/hostname. POSIX shell performs command substitution
inside double quotes, so a hostname containing $() or backticks would
be executed when the file is sourced (e.g., by rc(8)).
Switch to using the existing shell_escape() helper, which wraps values
in single quotes. In POSIX shell, single-quoted strings are completely
literal — no expansion or substitution of any kind is performed.
While the hostname is already validated to contain only
[a-zA-Z0-9.-], this change provides defense-in-depth so the output
format is safe regardless of future validation changes.

C++ exposes cfenv functions via using ::func. Our name-mangling
mechanism rewrites all function calls causing symbols such as
std::feclearexcept to be transformed into std::__feclearexcept_int.
Since no such function exists, compilation fails.
The using ::feclearexpect declarations themselves are unaffected because
