zinject: "no-op" error injection
When injected, this causes the matching IO to appear to succeed, but the
actual work is never submitted to the physical device. This can be used
to simulate a write-back cache servicing a write, but the backing device
has failed and the cache cannot complete the operation in the
background.

Add support for zfs mount -R <filesystem>
This commit adds support for mounting a dataset along with all of
it's children with '-R' flag for zfs mount. There can be scenarios
where we want to mount all datasets under one hierarchy instead of
mounting all datasets present on system with '-a' flag.

'-R' flag should work on all root and non-root datasets. Usage
information and man page has been updated for zfs mount. A test
for verifying the behavior for '-R' flag is also added.

1bf649cb0a vdev_disk: fix alignment check when buffer has non-zero starting offset
If a linear buffer spans multiple pages, and the first page has a
non-zero starting offset, the checker would not include the offset, and
so would think there was an alignment gap at the end of the first page,
rather than at the start.

That is, for a 16K buffer spread across five pages with an initial 512B
offset:

    [.XXXXXXX][XXXXXXXX][XXXXXXXX][XXXXXXXX][XXXXXXX.]

It would be interpreted as:

    [XXXXXXX.][XXXXXXXX]...

And be rejected as misaligned.

Since it's already a linear ABD, the "linearising" copy would just reuse
the buffer as-is, and the second check would failing, tripping the
VERIFY in vdev_disk_io_rw().

This commit fixes all this by including the offset in the check for
end-of-page alignment.

bc27c49404 tests: add test for vdev_disk page alignment check
This provides a test driver and a set of test vectors for the page
alignment check callback function vdev_disk_check_pages_cb().

Because there's no good facility for exposing this function to a
userspace test right now, for now I'm just duplicating the function and
adding commentary to remind people to keep them in sync.

Add ashift validation when adding devices to a pool
Currently, zpool add allows users to add top-level vdevs that have
different ashifts but doing so prevents users from being able to
perform a top-level vdev removal. Often times consumers may not realize
that they have mismatched ashifts until the top-level removal fails.

This feature adds ashift validation to the zpool add command and will
fail the operation if the sector size of the specified vdev does not
match the existing pool. This behavior can be disabled by using the -f
flag. In addition, new flags have been added to provide fine-grained
control to disable specific checks. These flags
are:

--allow-in-use
--allow-ashift-mismatch
--allow-replicaton-mismatch

The force flag will disable all of these checks.

Add slow disk diagnosis to ZED
Slow disk response times can be indicative of a failing drive. ZFS
currently tracks slow I/Os (slower than zio_slow_io_ms) and generates
events (ereport.fs.zfs.delay).  However, no action is taken by ZED,
like is done for checksum or I/O errors.  This change adds slow disk
diagnosis to ZED which is opt-in using new VDEV properties:
  VDEV_PROP_SLOW_IO_N
  VDEV_PROP_SLOW_IO_T

If multiple VDEVs in a pool are undergoing slow I/Os, then it skips
the zpool_vdev_degrade().

Add 'zpool status -e' flag to see unhealthy vdevs
When very large pools are present, it can be laborious to find
reasons for why a pool is degraded and/or where an unhealthy vdev
is. This option filters out vdevs that are ONLINE and with no errors
to make it easier to see where the issues are. Root and parents of
unhealthy vdevs will always be printed.

Testing:
ZFS errors and drive failures for multiple vdevs were simulated with
zinject.

BRT: Fix FICLONE/FICLONERANGE shortened copy
On Linux the ioctl_ficlonerange() and ioctl_ficlone() system calls
are expected to either fully clone the specified range or return an
error.  The range may be for an entire file.  While internally ZFS
supports cloning partial ranges there's no way to return the length
cloned to the caller so we need to make this all or nothing.

As part of this change support for the REMAP_FILE_CAN_SHORTEN flag
has been added.  When REMAP_FILE_CAN_SHORTEN is set zfs_clone_range()
will return a shortened range when encountering pending dirty records.
When it's clear zfs_clone_range() will block and wait for the records
to be written out allowing the blocks to be cloned.

Furthermore, the file range lock is held over the region being cloned
to prevent it from being modified while cloning.  This doesn't quite
provide an atomic semantics since if an error is encountered only a
portion of the range may be cloned.  This will be converted to an
error if REMAP_FILE_CAN_SHORTEN was not provided and returned to the
caller.  However, the destination file range is left in an undefined
state.

A test case has been added which exercises this functionality by
verifying that `cp --reflink=never|auto|always` works correctly.

L2ARC: Restrict write size to 1/4 of the device
PR #15457 exposed weird logic in L2ARC write sizing. If it appeared
bigger than device size, instead of liming write it reset all the
system-wide tunables to their default.  Aside of being excessive,
it did not actually help with the problem, still allowing infinite
loop to happen.

This patch removes the tunables reverting logic, but instead limits
L2ARC writes (or at least eviction/trim) to 1/4 of the capacity.

RAID-Z expansion feature
This feature allows disks to be added one at a time to a RAID-Z group,
expanding its capacity incrementally.  This feature is especially useful
for small pools (typically with only one RAID-Z group), where there
isn't sufficient hardware to add capacity by adding a whole new RAID-Z
group (typically doubling the number of disks).

== Initiating expansion ==

A new device (disk) can be attached to an existing RAIDZ vdev, by
running `zpool attach POOL raidzP-N NEW_DEVICE`, e.g. `zpool attach tank
raidz2-0 sda`.  The new device will become part of the RAIDZ group.  A
"raidz expansion" will be initiated, and the new device will contribute
additional space to the RAIDZ group once the expansion completes.

The `feature@raidz_expansion` on-disk feature flag must be `enabled` to
initiate an expansion, and it remains `active` for the life of the pool.
In other words, pools with expanded RAIDZ vdevs can not be imported by
older releases of the ZFS software.

== During expansion ==

The expansion entails reading all allocated space from existing disks in
the RAIDZ group, and rewriting it to the new disks in the RAIDZ group
(including the newly added device).

The expansion progress can be monitored with `zpool status`.

Data redundancy is maintained during (and after) the expansion.  If a
disk fails while the expansion is in progress, the expansion pauses
until the health of the RAIDZ vdev is restored (e.g. by replacing the
failed disk and waiting for reconstruction to complete).

The pool remains accessible during expansion.  Following a reboot or
export/import, the expansion resumes where it left off.

== After expansion ==

When the expansion completes, the additional space is available for use,
and is reflected in the `available` zfs property (as seen in `zfs list`,
`df`, etc).

Expansion does not change the number of failures that can be tolerated
without data loss (e.g. a RAIDZ2 is still a RAIDZ2 even after
expansion).

A RAIDZ vdev can be expanded multiple times.

After the expansion completes, old blocks remain with their old
data-to-parity ratio (e.g. 5-wide RAIDZ2, has 3 data to 2 parity), but
distributed among the larger set of disks.  New blocks will be written
with the new data-to-parity ratio (e.g. a 5-wide RAIDZ2 which has been
expanded once to 6-wide, has 4 data to 2 parity).  However, the RAIDZ
vdev's "assumed parity ratio" does not change, so slightly less space
than is expected may be reported for newly-written blocks, according to
`zfs list`, `df`, `ls -s`, and similar tools.

Fix ZED auto-replace for VDEVs using by-id paths
The change is simple -- restore the original code so that the VDEV 
path is updated when using by-id paths.  The more challenging part 
was to devise a second ZTS test, that would test auto-replace for 
'by-id' and help prevent a future regression.

With that new test, we can now do an A|B test with , and without, 
the fix to confirm that auto-replace for by-id paths works. The 
existing auto-replace test, functional/fault/auto_replace_001_pos, 
will confirm that we didn't break auto-replace for 'by-vdev' paths.

In the original functional/fault/auto_replace_001_pos test, the disk 
wipe (using dd) was not effective in removing the partitioning since 
the kernel was never informed of the wipe.

Added a call to wipefs(8) so that the kernel is informed and ZED will 
re-partition the device.
    
Added a validation step that the re-partitioning occurred by
confirming  that the GPT partition UUID changes.

54b1b1d893 import: require force when cachefile hostid doesn't match on-disk
Previously, if a cachefile is passed to zpool import, the cached config
is mostly offered as-is to ZFS_IOC_POOL_TRYIMPORT->spa_tryimport(), and
the results are taken as the canonical pool config and handed back to
ZFS_IOC_POOL_IMPORT.

In the course of its operation, spa_load() will inspect the pool and
build a new config from what it finds on disk. However, it then
regenerates a new config ready to import, and so rightly sets the hostid
and hostname for the local host in the config it returns.

Because of this, the "require force" checks always decide the pool is
exported and last touched by the local host, even if this is not true,
which is possible in a HA environment when MMP is not enabled. The pool
may be imported on another head, but the import checks still pass here,
so the pool ends up imported on both.

(This doesn't happen when a cachefile isn't used, because the pool
config is discovered in userspace in zpool_find_import(), and that does
find the on-disk hostid and hostname correctly).

Since the systemd zfs-import-cache.service unit uses cachefile imports,
this can lead to a system returning after a crash with a "valid"
cachefile on disk and automatically, quietly, importing a pool that has
already been taken up by a secondary head.

This commit causes the on-disk hostid and hostname to be included in the
ZPOOL_CONFIG_LOAD_INFO item in the returned config, and then changes the
"force" checks for zpool import to use them if present.

This method should give no change in behaviour for old userspace on new
kernels (they won't know to look for the new config items) and for new
userspace on old kernels (the won't find the new config items).

Add '-u' - nomount flag for zfs set
This commit adds '-u' flag for zfs set operation. With this flag,
mountpoint, sharenfs and sharesmb properties can be updated

Previously, if dataset was unmounted, and mountpoint property was
updated, dataset was not mounted after the update. This behavior
is changed in #15240. We mount the dataset whenever mountpoint
property is updated, regardless if it's mounted or not.

To provide the user with option to keep the dataset unmounted and
still update the mountpoint without mounting the dataset, '-u'
flag can be used.

If any of mountpoint, sharenfs or sharesmb properties are updated
with '-u' flag, the property is set to desired value but the
operation to (re/un)mount and/or (re/un)share the dataset is not
performed and dataset remains as it was before.

tests/block_cloning: try harder to stay on same txg in fallback test
We've observed this test failing intermittently. When it does, the
"same block" check shows that both files have the same content, that is,
the file was cloned.

The only way this could have happened is if the open txg moved between
the dd and clonefile calls. That's possible because although we set
zfs_txg_timeout to be large, that only affects the wait time in the sync
thread at the start of a new txg; it doesn't change anything if its
currently waiting or working.

So here we just force the txgs to move immediately before, which should
get both operations onto the same txg as intented.

bbac1d2977 Update the behavior of mountpoint property
There are some inconsistencies in the handling of mountpoint
property. This commit updates the behavior and makes it
consistent.

If mountpoint property is set when dataset is unmounted, this
would update the mountpoint property. The mountpoint could be
valid or invalid in this case. Setting the mountpoint property
would result in success in this case. Dataset would still be
unmounted here.

On the other hand, if dataset is mounted and mountpoint
property is updated to something invalid where mount cannot be
successful, for example, setting the mountpoint inside a readonly
directory. This would unmount the dataset, set the mountpoint
property to requested value and tries to mount the dataset. The
mount operation returns error and this error is treated as
overall failure of setting the property while the property is
actually set.

To make the behavior consistent in case dataset is mounted or
unmounted, we should try to mount the dataset whenever mountpoint
property is updated. This would result in mounting the datasets
if canmount property is set to on, regardless if the dataset was
previously unmounted.

The failure in mount operation while setting the mountpoint
property should not be treated as failure, since the property is
actually set now to user requested value.

Increase limit of redaction list by using spill block
Currently redaction bookmarks and their associated redaction lists
have a relatively low limit of 36 redaction snapshots. This is imposed
by the number of snapshot GUIDs that fit in the bonus buffer of the
redaction list object. While this is more than enough for most use
cases, there are some limited cases where larger numbers would be
useful to support.

We tweak the redaction list creation code to use a spill block if
the number of redaction snapshots is above the amount that would fit
in the bonus buffer. We also make a small change to allow spill blocks
to be use for types of data besides SA. In order to fully leverage
this logic, we also change the redaction code to use vmem_alloc, to
handle extremely large allocations if needed. Finally, small tweaks
were made to the zfs commands and the test suite.

tests/block_cloning: rename and document get_same_blocks helper
`get_same_blocks` is a helper to compare two files and return a list of
the blocks that are clones of each other. Its very necessary for block
cloning tests.

Previously it was incorrectly called `unique_blocks`, which is the
_inverse_ of what it does (an early version did list unique blocks; it
was changed but the name was not). So if nothing else, it should be
called `duplicate_blocks`.

But, keeping the details of a clone operation in your head is actually
quite difficult, without the additional overhead of wondering how the
tools work. So I've renamed it to better describe what it does, added a
usage note, and changed it to return block indexes from 0 instead of 1,
to match how L0 blocks are normally counted.

linux/copy_file_range: properly request a fallback copy on Linux <5.3
Before Linux 5.3, the filesystem's copy_file_range handler had to signal
back to the kernel that we can't fulfill the request and it should
fallback to a content copy. This is done by returning -EOPNOTSUPP.

This commit converts the EXDEV return from zfs_clone_range to
EOPNOTSUPP, to force the kernel to fallback for all the valid reasons it
might be unable to clone. Without it the copy_file_range() syscall will
return EXDEV to userspace, breaking its semantics.

Add test for copy_file_range fallbacks.  copy_file_range should always
fallback to a content copy whenever ZFS can't service the request with
cloning.

Ignore pool ashift property during vdev attachment
Ashift can be set for a vdev only during its creation, and the
top-level vdev does not change when a vdev is attached or replaced.
The ashift property should not be used during attachment, as it
does not allow attaching/replacing a vdev if the pool's ashift
property is increased after the existing vdev was created. Instead,
we should be able to attach the vdev if the attached vdev can
satisfy the ashift requirement with its parent.

btree: Implement faster binary search algorithm
This implements a binary search algorithm for B-Trees that reduces
branching to the absolute minimum necessary for a binary search
algorithm. It also enables the compiler to inline the comparator to
ensure that the only slowdown when doing binary search is from waiting
for memory accesses. Additionally, it instructs the compiler to unroll
the loop, which gives an additional 40% improve with Clang and 8%
improvement with GCC.

Consumers must opt into using the faster algorithm. At present, only
B-Trees used inside kernel code have been modified to use the faster
algorithm.

Micro-benchmarks suggest that this can improve binary search performance
by up to 3.5 times when compiling with Clang 16 and up to 1.9 times when
compiling with GCC 12.2.

Fix concurrent resilvers initiated at same time
For draid vdevs it was possible to initiate both the
sequential and healing resilver at same time.

This fixes the following two scenarios.
     1) There's a window where a sequential rebuild can
be started via ZED even if a healing resilver has been
scheduled.
	- This is fixed by adding additional check in
spa_vdev_attach() for any scheduled resilver and return
appropriate error code when a resilver is already in
progress.

     2) It was possible for zpool clear to start a healing
resilver when it wasn't needed at all. This occurs because
during a vdev_open() the device is presumed to be healthy not
until the device is validated by vdev_validate() and it's set
unavailable. However, by this point an async resilver will
have already been requested if the DTL isn't empty.
	- This is fixed by cancelling the SPA_ASYNC_RESILVER
request immediately at the end of vdev_reopen() when a resilver
is unneeded.

Finally, added a testcase in ZTS for verification.

Enable the head_errlog feature to remove errors
In case check_filesystem() does not error out and does not report
an error, remove that error block from error lists and logs
without requiring a scrub. This can happen when the original file and
all snapshots/clones referencing it have been removed.

Otherwise zpool status will still report that "Permanent errors have
been detected..." without actually reporting any of them.

To implement this change the functions introduced in corrective
receive were modified to take into account the head_errlog feature.

Before this change:
=============================
pool: test
 state: ONLINE

        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.

errors: Permanent errors have been detected in the following files:

After this change:
=============================
  pool: test
 state: ONLINE
status: One or more devices has experienced an unrecoverable error.  An
        attempt was made to correct the error.  Applications are
unaffected.
action: Determine if the device needs to be replaced, and clear the
errors
        using 'zpool clear' or replace the device with 'zpool replace'.

Allow zhack label repair to restore detached devices.
This commit expands on the zhack label repair command in d04b5c9 by
adding the -u option to undetach a device by regenerating uberblocks,
in addition to the existing functionality of fixing checksums, now
represented by -c. Previous behavior is retained in the case of no
options.

The changes are heavily inspired by Jeff Bonwick's labelfix
utility, as archived at:

https://gist.github.com/jjwhitney/baaa63144da89726e482

Additionally, it is now capable of properly determining the size of
block devices and other media, as well as handling sizes which are
not divisible by 2^18. This should make it viable for use on physical
devices and partitions, in addition to files.

These changes should make it possible to import zpools that have had
their uberblocks erased, such as in the case of pools rendered
inaccessible by erroneous detach commands.

Create zap for root vdev
And add it to the AVZ, this is not backwards compatible with older pools
due to an assertion in spa_sync() that verifies the number of ZAPs of
all vdevs matches the number of ZAPs in the AVZ.

Granted, the assertion only applies to #DEBUG builds - still, a feature
flag is introduced to avoid the assertion, com.klarasystems:vdev_zaps_v2

Notably, this allows to get/set properties on the root vdev:

    % zpool set user:prop=value <pool> root-0

Before this commit, it was already possible to get/set properties on
top-level vdevs with the syntax <type>-<vdev_id> (e.g. mirror-0):

    % zpool set user:prop=value <pool> mirror-0

This syntax also applies to the root vdev as it is is of type 'root'
with a vdev_id of 0, root-0. The keyword 'root' as an alias for
'root-0'.

The following tests have been added:

    - zpool get all properties from root vdev
    - zpool set a property on root vdev
    - verify root vdev ZAP is created

Fixes in persistent error log
Address the following bugs in persistent error log:

1) Check nested clones, eg "fs->snap->clone->snap2->clone2".

2) When deleting files containing error blocks in those clones (from
   "clone" the example above), do not break the check chain.

3) When deleting files in the originating fs before syncing the errlog
   to disk, do not break the check chain. This happens because at the
   time of introducing the error block in the error list, we do not have
   its birth txg and the head filesystem. If the original file is
   deleted before the error list is synced to the error log (which is
   when we actually lookup the birth txg and the head filesystem), then
   we do not have access to this info anymore and break the check chain.

The most prominent change is related to achieving (3). We expand the
spa_error_entry_t structure to accommodate the newly introduced
zbookmark_err_phys_t structure (containing the birth txg of the error
block).Due to compatibility reasons we cannot remove the
zbookmark_phys_t structure and we also need to place the new structure
after se_avl, so it is not accounted for in avl_find(). Then we modify
spa_log_error() to also provide the birth txg of the error block. With
these changes in place we simplify the previously introduced function
get_head_and_birth_txg() (now named get_head_ds()).

We chose not to follow the same approach for the head filesystem (thus
completely removing get_head_ds()) to avoid introducing new lock
contentions.

The stack sizes of nested functions (as measured by checkstack.pl in the
linux kernel) are:
check_filesystem [zfs]: 272 (was 912)
check_clones [zfs]: 64

We also introduced two new tests covering the above changes.

2) 2x zloop test (~10m) + 2x sanity test (~25m)
3) functional testings in parts 1..5 (each ~1h)
   - these could be triggered, when sanity tests are ok
   - currently I just start them all in the same time
4) cleanup and create summary

When everything is fine, the full run with all testings
should be done in around 2 hours.

The codeql.yml and checkstyle.yml are not part in this circle.

The testings are also modified a bit:
- report info about CPU and checksum benchmarks
- reset the debugging logs for each test
  - when some error occurred, we call dmesg with -c to get
    only the log output for the last failed test
  - we empty also the dbgsys

shown in zpool status #13675 is fixed the zfs_receive_corrective.ksh 
test no longer sets -o feature@head_errlog=disabled on pool creation 
so that it can also test for regressions related to head_errlog feature.

Note that the zfs_receive_compressed_corrective.ksh and
zfs_receive_large_block_corrective.ksh tests are still creating pools 
with -o feature@head_errlog=disabled.

d1807f168e nvpair: Constify string functions
After addressing coverity complaints involving `nvpair_name()`, the
compiler started complaining about dropping const. This lead to a rabbit
hole where not only `nvpair_name()` needed to be constified, but also
`nvpair_value_string()`, `fnvpair_value_string()` and a few other static
functions, plus variable pointers throughout the code. The result became
a fairly big change, so it has been split out into its own patch.
