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.

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.

To define USDT probes, dtrace -G makes use of relocations for undefined
symbols: the target address is overwritten with NOPs and the location is
recorded in the DOF section of the output object file. To avoid link
errors, the original relocation is destroyed. However, this means that
the same input object file cannot be processed multiple times, as
happens during incremental rebuilds. Instead, only set the relocation
type to NONE, so that all information required to reconstruct USDT
probes is preserved.

ZFS unmounts a dataset while receiving into it and remounts it afterwards.
But if ZFS is resuming an incomplete receive, it screws up and ends up with
a dataset that is mounted, but returns EIO for every access. This commit
fixes that condition.
While the vulnerable code also exists in OpenZFS, the problem is not
reproducible there. Apparently OpenZFS doesn't unmount the destination
dataset during receive, like FreeBSD does.

We are building new bootonce mechanism (previously zfs bootnext) and it is
based on this OpenZFS change. Since this patch is nicely self contained,
I am commiting it as is, and we can stack our changes.
Original patch description follows:
Modern bootloaders leverage data stored in the root filesystem to
enable some of their powerful features. GRUB specifically has a grubenv
file which can store large amounts of configuration data that can be
read and written at boot time and during normal operation. This allows
sysadmins to configure useful features like automated failover after
failed boot attempts. Unfortunately, due to the Copy-on-Write nature
of ZFS, the standard behavior of these tools cannot handle writing to
ZFS files safely at boot time. We need an alternative way to store
data that allows the bootloader to make changes to the data.
This work is very similar to work that was done on Illumos to enable
similar functionality in the FreeBSD bootloader. This patch is different
in that the data being stored is a raw grubenv file; this file can store
arbitrary variables and values, and the scripting provided by grub is
powerful enough that special structures are not required to implement
advanced behavior.
We repurpose the second padding area in each label to store the grubenv
file, protected by an embedded checksum. We add two ioctls to get and
set this data, and libzfs_core and libzfs functions to access them more
easily. There are no direct command line interfaces to these functions;
these will be added directly to the bootloader utilities.

We want newer versions of libzfs_core to run against an existing

for the ioc commands that rely on nvpair input arguments (i.e. non

This initial phase focuses on the non-legacy ioctls. A follow-on

The zfs_ioc_key_t for zfs_keys_channel_program looks like:

We've observed that on some highly fragmented pools, most metaslab
allocations are small (~2-8KB), but there are some large, 128K
allocations. The large allocations are for ZIL blocks. If there is a
lot of fragmentation, the large allocations can be hard to satisfy.
The most common impact of this is that we need to check (and thus load)
lots of metaslabs from the ZIL allocation code path, causing sync writes
to wait for metaslabs to load, which can take a second or more. In the
worst case, we may not be able to satisfy the allocation, in which case
the ZIL will resort to txg_wait_synced() to ensure the change is on
disk.
To provide a workaround for this, this change adds a tunable that can
reduce the size of ZIL blocks.

The DOF file output by dtrace -A contains only the loadable sections.
However, as it was created by a call to dtrace_dof_create() without
flags, the original DOF was created with the loadable sections. The
result is that the DOF includes the section headers for the unloadable
sections (COMMENTS and UTSNAME) without these sections actually being
present. This is inconsistent.
A simple change to anon_prog() ensures that the missing sections are
present in the outputted DOF. Alternatively, the call to
dtrace_dof_create() could pass the DTRACE_D_STRIP flag stripping out the
loadable sections. As the unloadable sections contain info useful for

Remove unnecessary txg syncs from receive_object() Closes#7197
This updates FreeBSD large_dnode code (that was imported from ZoL) to a
version that was committed to illumos. It has some cleanups,
improvements and fixes comparing to what we have in FreeBSD now.
I think that the most significant update is 8199 multi-threaded
dmu_object_alloc().
This commit reverts r351077 that was a revert of r351074 and r351076 and
restores those changes. Required atomic operations should be available
now on all platforms where we build ZFS.

The feature is implemented as an extension of the existing
ZFS_IOC_RENAME ioctl. Both the userland and the DSL interfaces support
renaming only a single bookmark at a time. As of now, there is no ZCP
interface to the new functionality. I am going to add it once the DSL
interface passes a test of time.
This change picks up support for zfs_ioc_namecheck_t::ENTITY_NAME that
was added to ZoL as part of Redacted Send/Receive feature by Paul
Dagnelie <pcd@delphix.com>. This is needed to allow a bookmark name in
zc_name.

Add a small wrapper around libzfs_core's lzc_send_space() to libzfs so
that every legacy ZFS_IOC_SEND consumer, along with their userland
counterpart estimate_ioctl(), can leverage ZFS_IOC_SEND_SPACE to
request send space estimation.
The legacy functionality in zfs_ioc_send() is left untouched for
compatibility purposes.

Although there is always a single stream and the total size in the
summary is always equal to the size reported for the stream, it's nice
to follow the usual output format.

We have long supported estimating a size of an incremental stream from a
snapshot. We should do the same for bookmarks as well.

This fixes a hole in the situation where the resume state is left from
receiving a new dataset and, so, the state is set on the dataset itself
(as opposed to %recv child).
Additionally, distinguish incremental and resume streams in error
messages.
This was also committed to ZoL:

In compare(), all error cases set the error code to EPIPE, so when an
error is set, the correct assertion to make is that the error is EPIPE,
not EINVAL.

They follow the conventions set by rw and sx lock probes. There is
an additional lockstat:::lockmgr-disown probe.
Update lockstat(1) to report on contention and hold events for
lockmgr locks. Document the new probes in dtrace_lockstat.4, and
deduplicate some of the existing probe descriptions.

In any pool without the extensible dataset feature flag already enabled,
creating a dataset with dedup set to use one of the new checksums would result
in the following panic as soon as any data was added:
panic[cpu0]/thread=ffffff0006761c40: feature_get_refcount(spa, feature,
&refcount) != 48 (0x30 != 0x30), file: ../../common/fs/zfs/zfeature.c line 390

Inspection showed that feature->fi_feature was 7, which is the value of
SPA_FEATURE_EXTENSIBLE_DATASET in the spa_feature enum.
Testing shows that the panic can be prevented by explicitly setting extensible
dataset as a dependency for the sha512, edonr, and skein feature flags.
Alternatively, the new checksums code could possibly be changed to obviate the
need for the dependency.

Many thanks to cryx-freebsd@h3q.com for reporting the problem and
submitting a fix. I have chosen to take an equivalent but textually
different patch from ZoL just to avoid increasing divergence between
OpenZFS flavours.
