bootonce feature is temporary, one time boot, activated by
"bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag.
By default, the bootonce setting is reset on attempt to boot and the next
boot will use previously active BE.
By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will
be set permanently active.
bootonce dataset name is recorded in boot pool labels, bootenv area.
in case of nextboot, the nextboot_enable boolean variable is recorded in
freebsd:nvstore nvlist, also stored in boot pool label bootenv area.
On boot, the loader will process /boot/nextboot.conf if nextboot_enable
is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf
processing on next boot.
bootonce and nextboot features are usable in both UEFI and BIOS boot.
To use bootonce/nextboot features, the boot loader needs to be updated on disk;
if loader.efi is stored on ESP, then ESP needs to be updated and
for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated
(gpart or other tools).
At this time, only lua loader is updated.

sys/ccompile.h no longer uses #pragma ident, so we no longer need to worry
about unknown pragmas.
I fixed one WARNS issue in r363409 by annotating be_is_auto_snapshot_name's
lbh parameter __unused, then upstreamed the following changes to OpenZFS
that rode in with the merge:
- zfs_path_to_zhandle now takes a const char *path rather than a char *path,
since it won't be mutating the string it receives and I had no reason to
believe it will need to in the future. [OpenZFS PR #10605]
- Annotated some unused parameters on definitions inlined into headers as
such. [OpenZFS PR #10606]
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.

This is the half of the changes required that work as-is with both in-tree
ZFS and the new hotness, sysutils/openzfs. Highlights are less dependency
on header pollution (from somewhere) and using 'mnttab' instead of
'extmnttab'. In the in-tree ZFS, the latter is a #define for the former,
but in the port extmnttab is actually a distinct struct that's a super-set
of mnttab. We really want mnttab here anyways, so just use it.
Imported BE, much like the activated BE, will not have an origin that we can
fetch/examine for destruction. be_destroy should not return BE_ERR_NOORIGIN
for failure to get the origin property for BE_DESTROY_AUTOORIGIN, because
we don't really know going into it that there's even an origin to be
destroyed.
BE_DESTROY_NEEDORIGIN has been renamed to BE_DESTROY_WANTORIGIN because only
a subset of it *needs* the origin, so 'need' is too strong of verbiage.
This was caught by jenkins and the bectl tests, but kevans failed to run the
bectl tests prior to commit.

New BEs can be created from either an existing snapshot or an existing BE.
If an existing BE is chosen (either implicitly via 'bectl create' or
explicitly via 'bectl create -e foo bar', for instance), then bectl will
create a snapshot of the current BE or "foo" with be_snapshot, with a name
formatted like: strftime("%F-%T") and a serial added to it.
This commit adds the needed bits for libbe or consumers to determine if a
snapshot names matches one of these auto-created snapshots (with some light
validation of the date/time/serial), and also a be_destroy flag to specify
that the origin should be automatically destroyed if possible.
A future commit to bectl will specify BE_DESTROY_AUTOORIGIN by default so we
clean up the origin in the most common case, non-user-managed snapshots.
The default package use to be FreeBSD-runtime but it should only contain
binaries and libs enough to boot to single user and repair the system, it
is also very handy to have a package that can be tranform to a small mfsroot.
So create a new package named FreeBSD-utilities and make it the default one.
Also move a few binaries and lib into this package when it make sense.

Further cleanup after r349380; loader and kernel will both ignore canmount
on the root dataset as well, so we should not be so strict about it when
mounting it. be_mount is restructured to make it more clear that depth==0 is
special, and to not try fetching these properties that we won't care about.

Other parts of libbe(3) were fairly strict on the mountpoint property of the
BE dataset, and be_mount was not much better. It was improved in r347027 to
allow mountpoint=none for depth==0, but this bit was still sensitive to
mountpoint != / and mountpoint != none. Given that other parts of libbe(3)
no longer restrict the mountpoint property here, and the rest of the base
system is generally OK and will assume that a BE is mounted at /, let's do
the same.

libbe currently only provides an API to create a recursive boot environment,
without any formal support for intentionally limiting the depth. This

restrict the depth of the new BE.

Our home-rolled solution didn't quite capture all of the details, and we
didn't actually validate snapshot names at all. zfs_name_valid captures the
important details, but it doesn't necessarily expose the errors that we're
wanting to see in the be_validate_* functions. Validating lengths
independently, then the names, should make this a non-issue.
To use bectl in an example, when one creates a new boot environment with
either `bectl create <be>` or `bectl create -e <otherbe> <be>`, libbe will
take a snapshot of the original boot environment to clone. Previously, this
used %F-%T date format as the snapshot name, but this has some limitations-
attempting to create multiple boot environments in quick succession may
collide if done within the same second.
Tack a serial onto it to reduce the chances of a collision... we could still
collide if multiple processes/threads are creating boot environments at the
same time, but this is likely not a big concern as this has only been
reported as occurring in freebsd-ci setup.

be_destroy is documented to recursively destroy a boot environment. In the
case of snapshots, one would take this to mean that these are also
recursively destroyed. However, this was previously not the case.
be_destroy would descend into the be_destroy callback and attempt to
zfs_iter_children on the top-level snapshot, which is bogus.
Our alternative approach is to take note of the snapshot name and iterate
through all of fs children of the BE to try destruction in the children.
The -o option is also fixed to work properly with deep BEs. If the BE was
created with `bectl create -e otherDeepBE newDeepBE`, for instance, then a
recursive snapshot of otherDeepBE would have been taken for construction of
newDeepBE but a subsequent destroy with BE_DESTROY_ORIGIN set would only
clean up the snapshot at the root of otherDeepBE: ${BEROOT}/otherDeepBE@...
The most recent iteration instead pretends not to know how these things
work, verifies that the origin is another BE and then passes that back
through be_destroy to DTRT when snapshots and deep BEs may be in play.
MFC after: 1 week
Currently origin snapshots are left behind when a BE is destroyed, whether
it was an auto-created snapshot or explicitly specified via, for example,
`bectl create -e be@mysnap ...`.
Removing it automatically could be argued as a POLA violation in some
circumstances, so provide a flag to be_destroy for it. An accompanying
option will be added to bectl(8) to utilize this.
Some minor style/consistency nits in the affected areas also addressed.

Previously, we directly used libzfs_core's lzc_receive to import to a
temporary snapshot, then cloned the snapshot and setup the properties. This
failed when attempting to import replication streams with questionable
error.
libzfs's zfs_receive is a much better fit here, so we now use it instead
with the destination dataset and let libzfs take care of the dirty details.
be_import is greatly simplified as a result.
