Fix the send --exclude option to work with encryption
When using --exclude, filtering needs to take place in two places:
in zfs_main.c via the callback previously added to support the
options, and in libzfs_sendrecv.c because it generates the nvlist
during a first pass, and that results in it complaining if the
excluded dataset is not available for sending. (eg, excluding an
encrypted dataset so you don't have to use --raw wouldn't work,
because the first pass would look at the dataset and decide you
couldn't use it.) Add send --exclude tests, including one that tests
excluding an encrypted hierarchy.

Add the --file-layout (-f) option to zdb(8)
Displays the physical raidz block layout for a given file.
This leverages the internal vdev_raidz_map_alloc() function to find
the map of how the block data is laid out across the child disks.

The column entry for each row looks like:
+------------+
|  D2     43 |
|     6020da |
+------------+
representing here the logical data column 2 that is 43 sectors high
starting at sector 0x6020da.

With -H, the output is a list of disks, LBAs, and block counts,
given in 512 byte block values.

draid: fix data corruption after disk clear
Currently, when there there are several faulted disks with attached
dRAID spares, and one of those disks is cleared from errors (zpool
clear), followed by its spare being detached, the data in all the
remaining spares that were attached while the cleared disk was in
FAULTED state might get corrupted (which can be seen by running scrub).
In some cases, when too many disks get cleared at a time, this can
result in data corruption/loss.

dRAID spare is a virtual device whose blocks are distributed among
other disks. Those disks can be also in FAULTED state with attached
spares on their own. When a disk gets sequentially resilvered (rebuilt),
the changes made by that resilvering won't get captured in the DTL
(Dirty Time Log) of other FAULTED disks with the attached spares to
which the data is written during the resilvering (as it would normally
be done for the changes made by the user if a new file is written or
some existing one is deleted). It is because sequential resilvering
works on the block level, without touching or looking into metadata,
so it doesn't know anything about the old BPs or transactions groups
that it is resilvering. So later on, when that disk gets cleared
from errors and healing resilvering is trying to sync all the data
from its spare onto it, all the changes made on its spare during the
resilvering of other disks will be missed because they won't be
captured in its DTL. That's why other dRAID spares may get corrupted.

Here's another way to explain it that might be helpful. Imagine a
scenario:

1. d1 fails and gets resilvered to some spare s1 - OK.
2. d2 fails and gets sequentially resilvered on draid spare s2. Now,
   in some slices, s2 would map to d1, which is failed. But d1 has s1
   spare attached, so the data from that resilvering goes to s1, but
   not recorded in d1's DTL.
3. Now, d1 gets cleared and its s1 gets detached. All the changes
   done by the user (writes or deletions) have their txgs captured
   in d1's DTL, so they will be resilvered by the healing resilver
   from its spare (s1) - that part works fine. But the data which
   was written during resilvering of d2 and went to s1 - that one
   will be missed from d1's DTL and won't get resilvered to it. So
   here we are:
4. s2 under d2 is corrupted in the slices which map to d1, because
   d1 doesn't have that data resilvered from s1.

Now, if there are more failed disks with draid spares attached which
were sequentially resilvered while d1 was failed, d3+s3, d4+s4 and
so on - all their spares will be corrupted. Because, in some slices,
each of them will map to d1 which will miss their data.

Solution: add all known txgs starting from TXG_INITIAL to DTLs of
non-writable devices during sequential resilvering so when healing
resilver starts on disk clear, it would be able to check and heal
blocks from all txgs.

libzfs: handle EDOM error in zpool_create
When creating a pool with devices that have incompatible block sizes,
the kernel returns EDOM. However, zpool_create() did not handle this
errno, falling through to zpool_standard_error() which produced a
confusing message about invalid property values.

Add a case EDOM handler in zpool_create() to return EZFS_BADDEV with
a descriptive auxiliary message, consistent with the existing EDOM
handler in zpool_vdev_add().

also a small adjustment to the test runner to allow OS-specific helper

  which were cleanly exported if the system and pool hostids don't

- mmp_inactive_import: an activity check is now required for any
  pool which wasn't cleanly exported, even if the system and pool

- mmp_on_uberblocks: updated expected uberblocks to take in to account
  the value MMP_INTERVAL_DEFAULT is set too.

- mmp_reset_interval: reduce the number of iterations from 10 to 3.
  This is sufficient to verify functionality and significantly speeds
  up the test.

- mmp_on_uberblocks: adjust the thresholds and increase the runtime
  to avoid false positives observed in CI.

- Update tests to use 'zhack action idle' instead of ztest to improve
  the reliability of the tests.

- Add additional log_note messages to test cases which have multiple
  verification steps to make it clear which portion of a test failed
  when reviewing the logs.

- Replace default_setup/cleanup_noexit calls with 'zpool create' and
  'zpool destroy' calls to avoid additional unnecessary dataset
  creation work.

- Update activity/noactivity check helper functions to use the
  ZFS_LOAD_INFO_DEBUG information now available from 'zpool import'
  to determine if this activity check ran and why.  This is more
  reliable in the CI than measuring the runtime.

- Removed all mmp tests from the zts-report.py exceptions list.

Fix history logging for zpool create -t
`zpool create` is supposed to log the command to the new pool’s history,
as a special record that never gets evicted from the ring buffer. but
when you create a pool with `zpool create -t`, no such record is ever
logged (#18102). that bug may be the cause of issues like #16408.

`zpool create -t` (83e9986f6e) and `zpool
import -t` (26b42f3f9d) are both designed
to override the on-disk zpool property `name` with an in-core
“temporary” name, but they work somewhat differently under the hood.

importing with a temporary name sets `spa->spa_import_flags |=
ZFS_IMPORT_TEMP_NAME` in ZFS_IOC_POOL_IMPORT, which tells
spa_write_cachefile() and spa_config_generate() to use the
ZPOOL_CONFIG_POOL_NAME in `spa->spa_config` instead of `spa->spa_name`.

creating with a temporary name permanently(!) sets the internal zpool
property `tname` (ZPOOL_PROP_TNAME) in the `zc->zc_nvlist_src` of
ZFS_IOC_POOL_CREATE, which tells zfs_ioc_pool_create()
(4ceb8dd6fd) and spa_create() to use that
name instead of `zc->zc_name`, then sets `spa->spa_import_flags |=
ZFS_IMPORT_TEMP_NAME` like an import.

but zfsdev_ioctl_common() fails to check for `tname` when saving the
pool name to `zfs_allow_log_key`, so when we call ZFS_IOC_LOG_HISTORY,
we call spa_open() on the wrong pool name and get ENOENT, so the logging
silently fails.

this patch fixes #18102 by checking for `tname` in zfsdev_ioctl_common()
like we do in zfs_ioc_pool_create().

stream is refused if the feature is active in the destination dataset
but the stream does not include the feature flag.

The problem is the feature is only activated when a large block is
born. If a large block has been born in the destination, but never
the source, the send can't work. This can arise when sending streams
back and forth between two datasets.

This commit fixes the problem by always activating the large blocks
feature when receiving a stream with the large block feature flag.

ZTS: add regression test for #17180
In #17180, we fixed an interesting bug that i believe i hit in one of my
pools, but as far as i can tell, there was no test for it.

this patch adds a regression test for #17180, minimised from my attempts
to reproduce the bug in a way that resembled the history of my pool.

CI: Add Alpine Linux 3.23 runner to the pipeline (#18087)
Add an Alpine Linux 3.23 runner to the CI chain to run OpenZFS builds
and tests against musl libc.

Currently, zfs_send_sparse is killed after 10 minutes on Alpine, causing
cascading EBUSY failures in the test suite. With zfs_send_sparse
disabled, the ZFS test suite reaches a pass rate of 94.62%.

This commit introduces the required Alpine-specific setup and a small
set of shell and cloud-init compatibility fixes that also apply to
existing Linux runners.

The Alpine runner is not enabled by default and is not executed for new
pull requests.

Ensure 64-bit off_t is used in user space instead of loff_t
Use 64-bit POSIX off_t in user space instead of the Linux kernel type
loff_t. This is enforced at configure time via AC_SYS_LARGEFILE and
AC_CHECK_SIZEOF([off_t]). loff_t remains in shared headers where they
mirror Linux VFS interfaces, and on FreeBSD we typedef loff_t to off_t
in those headers since libc does not provide it.

e282e98e79 libzpool: add zfs_impl.c, remove from libicp
This isn't used by libicp directly, but is by some clients, and relies
on headers specific to the zfs module, which makes using it difficult
otherwise.

Also switch the checksum tests over to use libzpool, so they can get
access to it. That's not exactly what we want in the long term, but the
icp and zfs modules have a complicated relationship so this will do for
now.

Only include the zfs headers where they're currently required to

in a bunch of internal zfs headers as a side effect.  We'll need
to move these structures in to a new shared header to avoid this.
We should not need to add the LIBZPOOL_CPPFLAGS when building the
zed, zinject, zpool, libzfs, ior libzfs_core.
