The ereport.fs.zfs.checksum event contains histograms of the bits that
were wrongly set or cleared according to their bit position in a 64-bit
word. So the maximum value that any histogram bucket could have would
be 64. But ZFS currently uses a uint32_t to hold each bucket. As a
result, the event report is full of needless zeroes.
Change the bucket size to uint8_t, stripping 768 needless zeros from
each event.

f6a0dac84 modified the zfs_iter_* functions to take a new "flags"
parameter, and introduced a variety of flags to ask the kernel to limit
the results in various ways, reducing the amount of work the caller
needed to do to filter out things they didn't need.
Unfortunately this change broke the ABI for existing clients (read:
older versions of the `zfs` program), and was reverted 399b98198.
dc95911d2 reintroduced the original patch, with the understanding that a
backwards-compatible fix would be made before the 2.2 release branch was
tagged. This commit is that fix.
This introduces zfs_iter_*_v2 functions that have the new flags
argument, and reverts the existing functions to not have the flags
parameter, as they were before. The old functions are now reimplemented
in terms of the new, with flags set to 0.

This had always worked in my testing, but a user on hardware reported
this to happen 100%, and I reproduced it once with cold VM host caches.
dracut-zfs-generator runs as a systemd generator, i.e. at Some
Relatively Early Time; if root= is a fixed dataset, it tries to
"solve [necessities] statically at generation time".
If by that point zfs-import.target hasn't popped (because the import is
taking a non-negligible amount of time for whatever reason), it'll see
no children for the root datase, and as such generate no mounts.
This has never had any right to work. No-one caught this earlier because
it's just that much more convenient to have root=zfs:AUTO, which orders
itself properly.
To fix this, always run zfs-nonroot-necessities.service;
this additionally simplifies the implementation by:
* making BOOTFS from zfs-env-bootfs.service be the real, canonical,
root dataset name, not just "whatever the first bootfs is",
and only set it if we're ZFS-booting
* zfs-{rollback,snapshot}-bootfs.service can use this instead of
re-implementing it
* having zfs-env-bootfs.service also set BOOTFSFLAGS
* this means the sysroot.mount drop-in can be fixed text
* zfs-nonroot-necessities.service can also be constant and always
enabled, because it's conditioned on BOOTFS being set
There is no longer any code generated at run-time
(the sysroot.mount drop-in is an unavoidable gratuitous cp).
The flow of BOOTFS{,FLAGS} from zfs-env-bootfs.service to sysroot.mount
is not noted explicitly in dracut.zfs(7), because (a) at some point it's
just visual noise and (b) it's already ordered via d-p-m.s from z-i.t.

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.

Current autotrim causes short-lived txg through:
1. calling txg_wait_synced() in metaslab_enable()
2. calling txg_wait_open() with should_quiesce = true
This patch addresses all the issues mentioned above.
A new cv, vdev_autotrim_kick_cv is added to kick autotrim activity.
It will be signaled once a txg is synced so that it does not change
the original autotrim pace. Also because it is a cv, the wait is
interruptible which speeds up the vdev_autotrim_stop_wait() call.
Finally, combining big zfs_txg_timeout, txg_wait_open() also causes
delay when exporting a pool.

we lie about a type always being aligned and then pass in stack

Of course, our SIMD code was written with unaligned accesses, so it

There is a window in the slog removal code where a panic loop could
ensue if the system crashes during that operation. The original design
of slog removal did not persisted any state because the removal happened
synchronously. This was changed by a later commit which persisted the
vdev_removing flag and exposed this bug. If a slog removal is in
progress and happens to crash after persisting the vdev_removing flag to
the label but before the vdev is removed from the spa config, then the
pool will continue to panic on import. Here's a sample of the panic:

Closes#14621Closes#14459
When traversing a tree of block pointers (e.g. for `zfs destroy <fs>` or
`zfs send`), we prefetch the indirect blocks that will be needed, in
`traverse_prefetch_metadata()`. In the case of `zfs destroy <fs>`, we
do a little traversing each txg, and resume the traversal the next txg.
So the indirect blocks that will be needed, and thus are candidates for
prefetching, does not include blocks that are before the resume point.
The problem is that the logic for determining if the indirect blocks are
before the resume point is incorrect, causing the (up to 1024) L1
indirect blocks that are inside the first L2 to not be prefetched. In
practice, if we are able to read many more than 1024 blocks per txg,
then this will be inconsequential. But if i/o latency is more than a
few milliseconds, almost no L1's will be prefetched, so they will be
read serially, and thus the destroying will be very slow. This can be
observed as `zpool get freeing` decreasing very slowly.
Specifically: When we first examine the L2 that contains the block we'll
be resuming from, we have not yet resumed, so `td_resume` is nonzero.
At this point, all calls to `traverse_prefetch_metadata()` will fail,
even if the L1 in question is after the resume point. It isn't until
the callback is issued for the resume point that we zero out
`td_resume`, but by this point we've already attempted and failed to
prefetch everything under this L2 indirect block.
This commit addresses the issue by reusing the existing
`resume_skip_check()` to determine if the L1's bookmark is before or
after the resume point. To do so, this function is made non-mutating
(the caller now zeros `td_resume`).
Note, this bug likely predates (was not introduced by) #11803.

kmodtool currently incorrectly identifies official

against them.

Remove arc_reduce_target_size() call from arc_prune_task(). The idea
of arc_prune_task() is to remove external references on ARC metadata,
such as vnodes. Since arc_prune_async() is called only from ARC itself,
it makes no sense to create a parasitic loop between ARC eviction and
the pruning, treatening to drop ARC to its minimum. I can't guess why
it was added as part of FreeBSD to OpenZFS integration.

031d7c2fe6 did not handle reverse
iteration, such that the original issue theoretically could still occur.
Note that contrary to the claim in the ZFS disk format specification
that a maximum of 6 levels are possible, 9 levels are possible with
recordsize=512 and and indirect block size of 16KB. In this unusual
configuration, span will be 65. The maximum size of span at 70 can be
reached at recordsize=16K and an indirect blocksize of 16KB.
When we are at this indirection level and are traversing backward, the
minimum value is start, but we cannot calculate that with 64-bit
arithmetic, so we avoid the calculation and instead rely on the earlier
statement that did `*offset = start;`.

This commit changes the workflow of the github actions.
We split the workflow into different parts:
1) build zfs modules for Ubuntu 20.04 and 22.04 (~25m)
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
