While we do support the "O bit" running a script (usually to start a
dhcpv6 client) we have no options for setups which set the "M bit" for,
e.g., static address assignment as in EC2.
Duplicate most of the "O bit" logic to also start a script for the
"M bit" with the one difference: if the "M bit" is set we will not
start the script for the "O bit" as well (per RFC 4861, Section 4.2).

The primary benefit is maintaining a completely shared
code base with the community allowing FreeBSD to receive
new features sooner and with less effort.
I would advise against doing 'zpool upgrade'
or creating indispensable pools using new
features until this change has had a month+
to soak.
Work on merging FreeBSD support in to what was
at the time "ZFS on Linux" began in August 2018.
I first publicly proposed transitioning FreeBSD
to (new) OpenZFS on December 18th, 2018. FreeBSD
support in OpenZFS was finally completed in December
2019. A CFT for downstreaming OpenZFS support in
to FreeBSD was first issued on July 8th. All issues
that were reported have been addressed or, for
a couple of less critical matters there are
pull requests in progress with OpenZFS. iXsystems
has tested and dogfooded extensively internally.
The TrueNAS 12 release is based on OpenZFS with
some additional features that have not yet made
it upstream.
Improvements include:
project quotas, encrypted datasets,
allocation classes, vectorized raidz,
vectorized checksums, various command line
improvements, zstd compression.
Thanks to those who have helped along the way:
Ryan Moeller, Allan Jude, Zack Welch, and many
others.

This should fix cases like su setting argv[0] to _su for /bin/sh.
Previously cheribsdbox (a crunched tool we use in CheriBSD to reduce the
size of our minimal disk images to allow loading them onto FPGAs without
waiting forever for the transfer) would complain about _su not being
compiled in, but now that we also look at AT_EXECPATH it correctly
invokes the sh tool.
Note: we use use AT_EXECPATH instead of the KERN_PROC_PATHNAME sysctl to get
the crunchgen binary name since it seems like KERN_PROC_PATHNAME just
returns the last cached path for a given hardlink.
When using `su`, instead of invoking /bin/csh this would invoke the last
used hardlink to cheribsdbox. This caused weird test failures when running
tests due to `id` being executed instead of `echo`:
$ id # id is a hardlink to /bin/cheribsdbox
$ su postgres -c 'echo 1' # su is also a hardlink
uid=1001(postgres) gid=1001(postgres) groups=1001(postgres)

The NVMe emulation code did not explicitly initialize queue head and
tail pointers on queue creation. As these pointers are part of
calloc()'ed memory, this only becomes a problem if the queues are
deleted and then recreated.
This error can manifest with messages about completions not matching a
command.
Some operating systems believe bhyve's emulated NVMe drive is failing
based on certain values in the SMART / Health Information log page being
zero. Fix is to set the reported temperature and available spare values
to reasonable defaults.

The -P flag is required by POSIX so we don't have to care whether pwd is
a shell builtin or not. This also allows removing pwd from the list of
bootstrap tools since all shells we care about for building have a
builtin pwd command. This effectively reverts r364190.

In r364166 I changed /bin/pwd to pwd, but pwd can be shell builtin that
may not correctly return a real path. To ensure that all symlinks are
resolved use `env pwd -P` instead (the -P flag is part of POSIX so
should be supported everywhere).

On Glibc systems mkstemp can only be used once with the same template
string since it will be modified in-place and no longer contain any 'X' chars.
It is fine to reuse the same file here but we need to be explicit and use
open() instead of mkstemp() on the second use.
While touching this file also avoid a hardcoded /bin/pwd since that may not
work when building on non-FreeBSD systems.

My change to allow bootstrapping pwd_mkdb (r363992) resulted in i386 build
failures because the bootstrap header was being included in non-bootstrap chpass.
Dropping the no longer required pwd_mkdb include path from chpass fixes
the build, but to be certain that the failure doesn't get re-introduced,
I've also moved the bootstrap pwd.h into a subdirectory so that adding
-I${SRCTOP}/usr.sbin/pwd_mkdb doesn't pull it in.

This breaks the build on macOS where this header doesn't exist. I could
also add a compat header to tools/build/cross-build but since it's not
needed removing it seems like the better solution.
We need to provide a struct passwd that is compatible with the target
system and this is not the case when cross-building from macOS/Linux.
It should also be a problem when bootstrapping for an i386 target from a
FreeBSD amd64 host since time_t does not match across those systems.
However, pwd_mkdb always truncates integer values to 32-bit so this
difference does not result in different databases.

Unfortunately it is impossible to implement SET IDENTIFYING INFORMATION,
since we have no persistent storage it requires, so the information is
