Umer Saleem d2f7b2e557 ZTS: Test for clone, mmap and write for block cloning
For block cloning, if we mmap the cloned file and write from the
map into the file, it triggers a panic in dbuf_redirty() on Linux.

The same scenario causes data corruption on FreeBSD. Both these
issues are fixed under PR#15656 and PR#15665.

It would be good to add a test for this scenario in ZTS. The test
program and issue was produced by @robn.

Alexander Motin 2e259c6f00 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.

Don Brady 0bcd1151f0 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.

Rob Norris 33d7c2d165 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).

Umer Saleem 8015e2ea66 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
without actually mounting or sharing the dataset.

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.

Umer Saleem e9dc31c74e 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.

Rob N 5f30698670 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

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.

Rob N 3af63683fe cmd: add 'help' subcommand to zpool and zfs
'program help subcommand' is a reasonably common pattern for
multifunction command-line programs. This commit adds support for that
style to the zpool and zfs commands.

When run as 'zpool help [<topic>]' or 'zfs help [<topic>]', executes the
'man' program on the PATH with the most likely manpage name for the
requested topic: "zpool-<topic>" or "zfs-<topic>" for subcommands, or
"zpool<topic>" or "zfs<topic>" for the "concepts" and "props" topics.
If no topic is supplied, uses the top "zpool" or "zfs" pages.

Rob N 084ff4abd2 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.

Rob N 92f095a903 copy_file_range: fix fallback when source create on same txg
In 019dea0a5 we removed the conversion from EAGAIN->EXDEV inside
zfs_clone_range(), but forgot to add a test for EAGAIN to the
copy_file_range() entry points to trigger fallback to a content copy.

This commit fixes that.

Rob N c47f0f4417 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.

Ameer Hamza d8011707cc 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.
