The recommended practice for `.Os` on FreeBSD is to not specify any
arguments. The correct OS name is used automatically.
Oddly enough, on the Linux distro I tested this on (CentOS 7), the man
pager defaulted to displaying "BSD" as the OS rather than "Linux". To
accommodate this, tack " Linux" back on in an install hook on Linux.
This is much simpler than removing it for FreeBSD when vendored in the
base system.

Allow zfs datasets to be mounted on Linux without relying on the
invocation of an external processes. This is the same behavior
which is implemented for FreeBSD.
Use of the libmount library was originally considered because it
provides functionality to properly lock and update the /etc/mtab
file. However, these days /etc/mtab is typically a symlink to
/proc/self/mounts so there's nothing to updated. Therefore, we
call mount(2) directly and avoid any additional dependencies.
If required the legacy behavior can be enabled by setting the
ZFS_MOUNT_HELPER environment variable. This may be needed in
environments where SELinux in enabled and the zfs binary does
not have mount permission.

Add a mechanism to wait for delete queue to drain.
When doing redacted send/recv, many workflows involve deleting files
that contain sensitive data. Because of the way zfs handles file
deletions, snapshots taken quickly after a rm operation can sometimes
still contain the file in question, especially if the file is very
large. This can result in issues for redacted send/recv users who
expect the deleted files to be redacted in the send streams, and not
appear in their clones.
This change duplicates much of the zpool wait related logic into a
zfs wait command, which can be used to wait until the internal
deleteq has been drained. Additional wait activities may be added
in the future.

This feature allows copying existing bookmarks using
zfs bookmark fs#target fs#newbookmark
There are some niche use cases for such functionality,
e.g. when using bookmarks as markers for replication progress.
Copying redaction bookmarks produces a normal bookmark that
cannot be used for redacted send (we are not duplicating
the redaction object).
ZCP support for bookmarking (both creation and copying) will be
implemented in a separate patch based on this work.
Overview:
- Terminology:
- source = existing snapshot or bookmark
- new/bmark = new bookmark
- Implement bookmark copying in `dsl_bookmark.c`
- create new bookmark node
- copy source's `zbn_phys` to new's `zbn_phys`
- zero-out redaction object id in copy
- Extend existing bookmark ioctl nvlist schema to accept
bookmarks as sources
- => `dsl_bookmark_create_nvl_validate` is authoritative
- use `dsl_dataset_is_before` check for both snapshot
and bookmark sources
- Adjust CLI
- refactor shortname expansion logic in `zfs_do_bookmark`
- Update man pages
- warn about redaction bookmark handling
- Add test cases
- CLI
- pyyzfs libzfs_core bindings

Preserved ".Os Linux", `.Os` macro parsing behavior differs between

Groff handles the `.Os` macro differently and wrongly, defaulting
it to "BSD" in `/usr/share/groff/*/tmac/mdoc/doc-common`, instead of
getting the default from `uname`.
A future set of changes will introduce build-time preprocessing of
manpages for platform-specific documentation and can insert the
correct operating system name.

Redacted send/receive allows users to send subsets of their data to
a target system. One possible use case for this feature is to not
transmit sensitive information to a data warehousing, test/dev, or
analytics environment. Another is to save space by not replicating
unimportant data within a given dataset, for example in backup tools
like zrepl.
Redacted send/receive is a three-stage process. First, a clone (or
clones) is made of the snapshot to be sent to the target. In this
clone (or clones), all unnecessary or unwanted data is removed or
modified. This clone is then snapshotted to create the "redaction
snapshot" (or snapshots). Second, the new zfs redact command is used
to create a redaction bookmark. The redaction bookmark stores the
list of blocks in a snapshot that were modified by the redaction
snapshot(s). Finally, the redaction bookmark is passed as a parameter
to zfs send. When sending to the snapshot that was redacted, the
redaction bookmark is used to filter out blocks that contain sensitive
or unwanted information, and those blocks are not included in the send
stream. When sending from the redaction bookmark, the blocks it
contains are considered as candidate blocks in addition to those
blocks in the destination snapshot that were modified since the
creation_txg of the redaction bookmark. This step is necessary to
allow the target to rehydrate data in the case where some blocks are
accidentally or unnecessarily modified in the redaction snapshot.
The changes to bookmarks to enable fast space estimation involve
adding deadlists to bookmarks. There is also logic to manage the
life cycles of these deadlists.
The new size estimation process operates in cases where previously
an accurate estimate could not be provided. In those cases, a send
is performed where no data blocks are read, reducing the runtime
significantly and providing a byte-accurate size estimate.

zfs.8 correctly said that GRUB did not support them, but
zpool-features.5 said that "Booting off pools...is supported." Now,
zpool-features.5 discusses GRUB specifically and indicates its lack of
support for these features. Also, I have clarified the wording in both
places to indicate that the pool feature cannot be used. It's not a
filesystem dataset thing, but pool-wide.
I described this as "cannot be used". I think technically the feature
can be enabled, just not active. However, the effect is essentially the
same: you cannot enable those checksum algorithms on any dataset in the
pool, so you might as well not enable the feature (which is just
pointing a loaded gun at your foot). In the past, an argument could be
made that having all the features enabled was useful for simplicity, as
long as you didn't activate the GRUB-incompatible features, but that's
getting less and less realistic over time. A user can still do that,
but we should not encourage that.

Currently, there is an issue in the raw receive code where
raw receives are allowed to happen on top of previously
non-raw received datasets. This is a problem because the
source-side dataset doesn't know about how the blocks on
the destination were encrypted. As a result, any MAC in
the objset's checksum-of-MACs tree that is a parent of both
blocks encrypted on the source and blocks encrypted by the
destination will be incorrect. This will result in
authentication errors when we decrypt the dataset.
This patch fixes this issue by adding a new check to the
raw receive code. The code now maintains an "IVset guid",
which acts as an identifier for the set of IVs used to
encrypt a given snapshot. When a snapshot is raw received,
the destination snapshot will take this value from the
DRR_BEGIN payload. Non-raw receives and normal "zfs snap"
operations will cause ZFS to generate a new IVset guid.
When a raw incremental stream is received, ZFS will check
that the "from" IVset guid in the stream matches that of
the "from" destination snapshot. If they do not match, the
code will error out the receive, preventing the problem.
This patch requires an on-disk format change to add the
IVset guids to snapshots and bookmarks. As a result, this
patch has errata handling and a tunable to help affected
users resolve the issue with as little interruption as
possible.

The implementation of 'zfs remap' has proven to be problematic since
it modifies the objset (but not its logical contents) by dirtying
metadata without owning it. The consequence of which is that
dmu_objset_remap_indirects() is vulnerable to certain races.
For example, if we are in the middle of receiving into the filesystem
while it is being remapped. Then it is possible we could evict the
objset when the receive completes (see dsl_dataset_clone_swap_sync_impl,
or dmu_recv_end_sync), but dmu_objset_remap_indirects() may be still
using the objset. The result of which would be a panic.
Extended runs of ztest(8) have exposed other possible races which
can occur when using 'zfs remap'. Several of these have been fixed
but there may be others which have not yet been encountered and
diagnosed.
Furthermore, the ability to manually remap a filesystem is no longer
particularly useful now that the removal code can map large chunks.
Coupled with the fact that explaining what this command does and why
it may be useful requires a detailed understanding of the internals
of device removal. These are details users should not be bothered
with.
Therefore, the 'zfs remap' command is being disabled but not entirely
removed. It may be removed in the future or potentially reworked
to address the issues described above. Since 'zfs remap' has never
been part of a tagged release its removal is expected to have
minimal impact.
The ZTS tests have been updated to continue to exercise the command
to prevent atrophy, but it has been removed entirely from ztest(8).

The following patch introduces a few statistics on reads and writes
grouped by dataset. These statistics are implemented as kstats
(backed by aggregate sums for performance) and can be retrieved by
using the dataset objset ID number. The motivation for this change is
to provide some preliminary analytics on dataset usage/performance.

One small integration that was absent from b52563 was
support for zfs recv -o / -x with regards to encryption
parameters. The main use cases of this are as follows:
* Receiving an unencrypted stream as encrypted without
needing to create a "dummy" encrypted parent so that
encryption can be inheritted.
* Allowing users to change their keylocation on receive,
so long as the receiving dataset is an encryption root.
* Allowing users to explicitly exclude or override the
encryption property from an unencrypted properties stream,
allowing it to be received as encrypted.
* Receiving a recursive heirarchy of unencrypted datasets,
encrypting the top-level one and forcing all children to
inherit the encryption.

Porting notes:
* As of grub-2.02 these checksums are not supported. However, as
pointed out in #6501 there are alternatives such as EFISTUB which
work and have no such restriction. A warning was added to the
checksum property section of the zfs.8 man page.

Datasets that are deeply nested (~100 levels) are impractical. We just
put a limit of 50 levels to newly created datasets. Existing datasets
should work without a problem.
The problem can be seen by attempting to create a dataset using the -p
option with many levels:

Porting notes:
* Added zfs_max_dataset_nesting module option with documentation.
* Updated zfs_rename_014_neg.ksh for Linux.
* Increase the zfs.sh stack warning to 15K. Enough time has passed
that 16K can be reasonably assumed to be the default value. It
was increased in the 3.15 kernel released in June of 2014.
