We hit an assertion trying to run `zdb -bvy` on a large pool. But
it seems the code does not really need size there, since we only

This changes the basic search algorithm from a single search up and down
the tree to a full depth-first traversal to handle conditions where the
tree matches at a higher level but not a lower level.
Normally higher level blocks always point to matching blocks, but there
are cases where this does not happen:
1. Racing block pointer updates from dbuf_write_ready.
Before f664f1ee7f (#8946), both dbuf_write_ready and
dnode_next_offset held dn_struct_rwlock which protected against
pointer writes from concurrent syncs.
This no longer applies, so sync context can f.e. clear or fill all
L1->L0 BPs before the L2->L1 BP and higher BP's are updated.
dnode_free_range in particular can reach this case and skip over L1
blocks that need to be dirtied. Later, sync will panic in
free_children when trying to clear a non-dirty indirect block.
This case was found with ztest.
2. txg > 0, non-hole case. This is #11196.
Freeing blocks/dnodes breaks the assumption that a match at a higher
level implies a match at a lower level when filtering txg > 0.
Whenever some but not all L0 blocks are freed, the parent L1 block is
rewritten. Its updated L2->L1 BP reflects a newer birth txg.
Later when searching by txg, if the L1 block matches since the txg is
newer, it is possible that none of the remaining L1->L0 BPs match if
none have been updated.
The same behavior is possible with dnode search at L0.
This is reachable from dsl_destroy_head for synchronous freeing.
When this happens open context fails to free objects leaving sync
context stuck freeing potentially many objects.
This is also reachable from traverse_pool for extreme rewind where it
is theoretically possible that datasets not dirtied after txg are
skipped if the MOS has high enough indirection to trigger this case.
In both of these cases, without backtracking the search ends prematurely
as ESRCH result implies no more matches in the entire object.

level. These are:
1. When a pool contains mixed file and disk vdevs.
2. When a pool contains an active dRAID distributed spare
3. When a pool contains an active hot spare
The lack of warnings are caused by get_replication() assessing
the current pool configuration an inconsistent and disabling
the mismatched replication check for the new pool configuration
after 'zpool add'. This change updates get_replication() to
be slightly more tolerant in the non-fatal case.

In syncing mode, zfs_putpages() would put the entire range of pages onto
the ZIL, then return VM_PAGER_OK for each page to the kernel. However,
an associated zil_commit() or txg sync had not happened at this point,
so the write may not actually be on disk.
So, we rework that case to use a ZIL commit callback, and do the
post-write work of undirtying the page and signaling completion there.
We return VM_PAGER_PEND to the kernel instead so it knows that we will
take care of it.
The original version of this (238eab7dc1) copied the Linux model and did
the cleanup in a ZIL callback for both async and sync. This was a
mistake, as FreeBSD does not have a separate "busy for writeback" flag
like Linux which keeps the page usable. The full sbusy flag locks the
entire page out until the itx callback fires, which for async is after
txg sync, which could be literal seconds in the future.
For the async case, the data is already on the DMU and the in-memory
ZIL, which is sufficient for async writeback, so the old method of
logging it without a callback, undirtying the page and returning is more
than sufficient and reclaims that lost performance.

When examining the root dataset with zdb -k, we get into a mismatched

The redundant_metadata setting in ZFS allows users to trade resilience
for performance and space savings. This applies to all data and metadata
blocks in zfs, with one exception: gang blocks. Gang blocks currently
just take the copies property of the IO being ganged and, if it's 1,
sets it to 2. This means that we always make at least two copies of a
gang header, which is good for resilience. However, if the users care
more about performance than resilience, their gang blocks will be even
more of a penalty than usual.
We add logic to calculate the number of gang headers copies directly,
and store it as a separate IO property. This is stored in the IO
properties and not calculated when we decide to gang because by that
point we may not have easy access to the relevant information about what
kind of block is being stored. We also check the redundant_metadata
property when doing so, and use that to decide whether to store an extra
copy of the gang headers, compared to the underlying blocks.

than psize for compressed blocks, the checksum is calculated on

checksum on physical, i.e. compressed data. So reading the same block
produces different checksum results depending on how we read it,
whether we decompress it or not, which, again, makes no sense.
Fix: use psize instead of lsize when calculating the checksum so that
it is always calculated on the physical block size, no matter was it
compressed or not.

it doesn't do that reliably at most fragmentation levels. This means
that recalculated metaslabs are forced to a weight that isn't really

ZIL introduced dependencies between its write ZIOs to permit flush
defer, when we flush vdev caches only once all the write ZIOs has
completed. But it was recently spotted that it serializes not only
ZIO completions handling, but also their ready stage. It means ZIO
pipeline can't calculate checksums for the following ZIOs until all
the previous are checksumed, even though it is not required. On a
systems where memory throughput of a single CPU core is limited,
it creates single-core CPU bottleneck, which is difficult to see
due to ZIO pipeline design with many taskqueue threads.
While it would be great to bypass the ready stage waits, it would
require changes to ZIO code, and I haven't found a clean way to do
it. But I've noticed that we don't need any dependency between
the write ZIOs if the previous one has some waiters, which means
it won't defer any flushes and work as a barrier for the earlier
ones.
Bypassing it won't help large single-thread writes, since all the
write ZIOs except the last in that case won't have waiters, and
so will be dependent. But in that case the ZIO processing might
not be a bottleneck, since there will be only one thread populating
the write buffers, that will likely be the bottleneck.
But bypassing the ZIO dependency on multi-threaded write workloads
really allows them to scale beyond the checksuming throughput of
one CPU core.

Closes#17308
It makes no sense to limit read size below the block size, since
DMU will any way consume resources for the whole block, while the
current zfs_vnops_read_chunk_size is only 1MB, which is smaller
that maximum block size of 16MB. Plus in case of misaligned
Uncached I/O the buffer may get evicted between the chunks,
requiring repeating I/Os.
On 64-bit platforms increase zfs_vnops_read_chunk_size to 32MB.
It allows to less depend on speculative prefetcher if application
requests specific size, first not waiting for prefetcher to start
and later not prefetching more than needed.
Also while there, we don't need to align reads to the chunk size,
but only to a block size, which is smaller and so more forgiving.
My profiles show ~4% of CPU time saving when reading 16MB blocks.

On systems with enormous amounts of memory, the single arc_evict thread
can become a bottleneck if reads and writes are stuck behind it, waiting
for old data to be evicted before new data can take its place.
This commit adds support for evicting from multiple ARC lists in
parallel, by farming the evict work out to some number of threads and
then accumulating their results.
A new tuneable, zfs_arc_evict_threads, sets the number of threads. By
default, it will scale based on the number of CPUs.

Closes#16486
This also includes removing L2 vdevs asynchronously.
This commit also guarantees that spa_load_guid is unique.
The zpool reguid feature introduced the spa_load_guid, which is a
transient value used for runtime identification purposes in the ARC.
This value is not the same as the spa's persistent pool guid.
However, the value is seeded from spa_generate_load_guid() which
does not check for uniqueness against the spa_load_guid from other
pools. Although extremely rare, you can end up with two different
pools sharing the same spa_load_guid value! So we guarantee that
the value is always unique and additionally not still in use by an
async arc flush task.

zfs_putpages() would put the entire range of pages onto the ZIL, then
return VM_PAGER_OK for each page to the kernel. However, an associated
zil_commit() or txg sync had not happened at this point, so the write
may not actually be on disk.
So, we rework it to use a ZIL commit callback, and do the post-write
work of undirtying the page and signaling completion there. We return
VM_PAGER_PEND to the kernel instead so it knows that we will take care

(cherry picked from commit bb740d66de)
d634d20d1b had been intended to fix a
potential information leak issue where the compiler's optimization
passes appeared to remove `memset()` operations that sanitize sensitive
data before memory is freed for use by the rest of the kernel.
When I wrote it, I had assumed that the compiler would not remove the
other `memset()` operations, but upon reflection, I have realized that
this was a bad assumption to make. I would rather have a very slight
amount of additional overhead when calling `gcm_clear_ctx()` than risk a
future compiler remove `memset()` calls. This is likely to happen if
someone decides to try doing link time optimization and the person will
not think to audit the assembly output for issues like this, so it is
best to preempt the possibility before it happens.

(cherry picked from commit d8a33bc0a5)
Bisecting identified the redacted send/receive as the source of the bug
for issue #12014. Specifically the call to
dsl_dataset_hold_obj(&fromds) has been replaced by
dsl_dataset_hold_obj_flags() which passes a DECRYPT flag and creates
a key mapping. A subsequent dsl_dataset_rele_flag(&fromds) is missing
and the key mapping is not cleared. This may be inadvertedly used, which
results in arc_untransform failing with ECKSUM in:
arc_untransform+0x96/0xb0 [zfs]
dbuf_read_verify_dnode_crypt+0x196/0x350 [zfs]

Fix this by restoring the call to dsl_dataset_hold_obj().
The same applies for to_ds: here replace dsl_dataset_rele(&to_ds) with
dsl_dataset_rele_flags().
Both leaked key mappings will cause a panic when exporting the
sending pool or unloading the zfs module after a non-raw send from

(cherry picked from commit ea74cdedda)
Currently, commands that resume a scrub/errorscrub from a paused state
don't get logged in the pool history. This is because resumes actually
return ECANCELED, instead of 0. This causes the tsd code in the common
ioctl logic to not think the ioctl succeeded, which causes the
log_history ioctl to fail with EPERM. However, for resuming a scrub from
a paused state, ECANCELED is success.
There are two options for how to deal with this. The first is the one
that I implemented here; I can't find a good reason for dmu_scan to
return ECANCELED on resume instead of 0, so let's just not. The only
place we check for the ECANCELED value is in zpool_scan, where we just
convert it back to zero. However, I am aware that this is changing an
ioctl interface, which I believe is a breaking change. I don't think
it's an important change, but maybe there is someone who relies on it.
The other option that could be implemented is to either allow ECANCELED
specifically from dsl_scan in the common ioctl code, or add a generic
facility to the common ioctl code that allows each command to specify
whether or not success happened, regardless of the return values. I am
open to feedback on which option people think would be better.

included into NR_FILE_PAGES. But it is actually a non-evictable

parameter makes ARC to ignore shrinker requests while page cache
does not really have anything to evict, ending up in OOM killer
killing the QEMU process.
Instead use of NR_ACTIVE_FILE + NR_INACTIVE_FILE should represent
the part of a page cache that is actually evictable, which should
be safer to use as a reference for ARC scaling.

Allow installing a custom kernel version from the Fedora experimental

ZFS works against a newer kernel.
Fedora has a number of repos with experimental kernel packages. This
PR allows installs from kernels in these repos:
@kernel-vanilla/stable
@kernel-vanilla/mainline
(https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories)
You will need to manually kick of a github runner to test with a custom
kernel version. To do that, go to the github actions tab under
'zfs-qemu' and click the drop-down for 'run workflow'. In there you
will see a text box to specify the version (like '6.14'). The scripts
will do their best to match the version to the newest matching version
that the repos support (since they're may be multiple nightly versions
of, say, '6.14'). A full list of kernel versions can be seen in the
dependency stage output if you kick off a manual run.

Once we've selected a best ident for the AUTHORS file, it makes sense to
set up a corresponding mailmap entry for any other ident for that
committer, to ensure the git history also reflects this into the future.
So, here we output potential mailmap updates for a human to consider.
For the moment, this needs to be done by a human, because update_authors
uses git to get the author names, and thus is reliant on the mailmap
contents to generate its output, so having it update mailmap directly
would introduce a circular dependency that I'm not totally sure about.
It's definitely better than having to go back through the history and
check each commit by hand though.

I've increasingly found that commits from new contributors have the
author set in the "Github noreply" obfuscated style. If they do have a
better canonical choice, it's usually in the Signed-off-by: trailer in
the commit message.
I had avoided using these in the first version of this program because
they aren't always present, aren't always correct, and some commits have
multiple signoffs. It seems however that requiring either the name or
the email address to match the commit author sufficiently narrows the
scope to be useful for the "Github noreply" situation, which is really
the main sticking point. And of course, if it gets it wrong, overriding
in .mailmap or AUTHORS is always an option.

The old code would compare all the test group names to work out some
sort of common path, but it didn't appear to work consistently,
sometimes placing output in a top-level dir, other times in one or more
subdirs. (I confess, I do not quite understand what it's supposed to
do).
This is a very simple rework that simply looks at all the test group
paths, removes common leading components, and uses the remainder as the
output directory. This should work because groups paths are unique, and
means we get a output dir tree of roughly the same shape as the test
groups in the runfiles and the test source dirs themselves.

This generalises the API as txg_wait_synced_flags(), where the provided

Instead of a boolean, the return is now an error code, which the caller

Closes#17235
(cherry picked from commit aa46cc9812)
### Background
Various admin operations will be invoked by some userspace task, but the
work will be done on a separate kernel thread at a later time. Snapshots
are an example, which are triggered through zfs_ioc_snapshot() ->
dsl_dataset_snapshot(), but the actual work is from a task dispatched to
dp_sync_taskq.
Many such tasks end up in dsl_enforce_ds_ss_limits(), where various
limits and permissions are enforced. Among other things, it is necessary
to ensure that the invoking task (that is, the user) has permission to
do things. We can't simply check if the running task has permission; it
is a privileged kernel thread, which can do anything.
However, in the general case it's not safe to simply query the task for
its permissions at the check time, as the task may not exist any more,
or its permissions may have changed since it was first invoked. So
instead, we capture the permissions by saving CRED() in the user task,
and then using it for the check through the secpolicy_* functions.
### Current implementation
The current code calls CRED() to get the credential, which gets a
pointer to the cred_t inside the current task and passes it to the
worker task. However, it doesn't take a reference to the cred_t, and so
expects that it won't change, and that the task continues to exist. In
practice that is always the case, because we don't let the calling task
return from the kernel until the work is done.
For Linux, we also take a reference to the current task, because the
Linux credential APIs for the most part do not check an arbitrary
credential, but rather, query what a task can do. See
secpolicy_zfs_proc(). Again, we don't take a reference on the task, just
a pointer to it.
### Changes
We change to calling crhold() on the task credential, and crfree() when
we're done with it. This ensures it stays alive and unchanged for the
duration of the call.
On the Linux side, we change the main policy checking function
priv_policy_ns() to use override_creds()/revert_creds() if necessary to
make the provided credential active in the current task, allowing the
standard task-permission APIs to do the needed check. Since the task
pointer is no longer required, this lets us entirely remove
secpolicy_zfs_proc() and the need to carry a task pointer around as
well.

Various tools will display draid vdev names with parameters embedded in
them, but would not accept them as valid vdev names when looking them
up, making it difficult to build pipelines involving draid vdevs.
This commit makes it so that if a full draid name is offered for match,
it gets truncated at the first ':' character.

(cherry picked from commit 09f4dd06c3)
Previous implementation of zap_leaf_array_free() put chunks on the
free list in reverse order. Also zap_leaf_transfer_entry() and
zap_entry_remove() were freeing name and value arrays in reverse
order. Together this created a mess in the free list, making
following allocations much more fragmented than necessary.
This patch re-implements zap_leaf_array_free() to keep existing
chunks order, and implements non-destructive zap_leaf_array_copy()
to be used in zap_leaf_transfer_entry() to allow properly ordered
freeing name and value arrays there and in zap_entry_remove().
With this change test of some writes and deletes shows percent of
non-contiguous chunks in DDT reducing from 61% and 47% to 0% and
17% for arrays and frees respectively. Sure some explicit sorting
could do even better, especially for ZAPs with variable-size arrays,
but it would also cost much more, while this should be very cheap.

RPM to 6.14, but hold back kernel-devel at 6.13, for example.

IVs != 96 bits get hashed with GHASH to bring them to 96 bits. Any call
to GHASH will mix the ghash state in gcm_ghash. This is expected to be
zero at first use in an encrypt or decrypt operation, so it needs to be
zeroed after using GHASH in setup.
gcm_init() does this, but gcm_avx_init() zeroed it before setup, not
after, resulting in incorrect encrypt/decrypt results when using AVX GCM
with an IV != 96 bits.
OpenZFS _always_ uses a 96 bit IV (ZIO_DATA_IV_LEN) so this will never
have been hit in any real-world use, which is extremely fortunate, as we
would have incorrectly-encrypted data on-disk. Still, as long as we have
this code here we should make sure it's correct.

doesn't appear to be able to cause any refcount leaks (after the fix in

Currently, the zfs initramfs-tools boot script under local-top calls
`vgchange -ay`, which unconditionally activates all logical volumes
(LVs) in all discovered volume groups (VGs). This causes all LVs to be
active after boot. However, users may prefer to not activate certain
VGs/LVs on boot. They might normally use the `--setautoactivation n`
VG/LV flag or the `auto_activation_volume_list` LVM config option to
achieve this, but since the script unconditionally activates all LVs,
neither has an effect.
To fix this, call `vgchange -aay` instead. This triggers LVM
autoactivation, which honors autoactivation settings such as the
`--setautoactivation` flag. It is also more in line with the LVM
documentation, which says autoactivation is "meant to be used by
activation commands that are run automatically by the system" [1].
Note that this change might break misconfigured setups that have ZFS
on top of an LV for which autoactivation is disabled.

is serialized via sb->s_umount rwsem, only when that lock is taken
is it okay to work with s_flags - and the other mistake I was doing

The actual ZTS scripts are simple drivers for the crypto_test program in
it's "correctness" mode. This mode takes a file full of test vectors
(inputs and expected outputs), runs them, and checks that the results

algorithm provided by the ICP.
The test vectors are taken from Project Wycheproof, which provides a
huge number of tests, including exercising many edge cases and common
implementation mistakes. These tests are provided are JSON files, so a
program is included here to convert them into a simpler line-based
format for crypto_test to consume.
crypto_test also has a "performance" mode, which will run simple
benchmarks against all implementations provded by the ICP and output
them for comparison. This is not used by ZTS, but is available to assist
with development of new implementations of the underlying primitives.

Force receive (zfs receive -F) can rollback or destroy snapshots and
file systems that do not exist on the sending side (see zfs-receive man
page). This means an user having the receive permission can effectively
delete data on receiving side, even if such user does not have explicit
rollback or destroy permissions.
This patch adds the receive:append permission, which only permits
limited, non-forced receive. Behavior for users with full receive
permission is not changed in any way.

Closes#17139
Implementation of DDT pruning introduced verification of DVAs in
a block pointer during ddt_lookup() to not by mistake free previous
pruned incarnation of the entry. But when writing a new block in
zio_ddt_write() we might have the DVAs only from override pointer,
which may never have "D" flag to be confused with pruned DDT entry,
and we'll abandon those DVAs if we find a matching entry in DDT.
This fixes deduplication for blocks written via dmu_sync() for
purposes of indirect ZIL write records, that I have tested. And
I suspect it might actually allow deduplication for Direct I/O,
even though in an odd way -- first write block directly and then
delete it later during TXG commit if found duplicate, which part
I haven't tested.

We're expected to return both memory and IO alignment. For memory, it's
always PAGE_SIZE. For IO, we return the current block size for the file,
which is the required alignment for an arbitrary block, and for the

Closes#17078
since 4.10, bio->bi_opf needs to be checked to determine all kinds of
flush requests. this was the case prior to the commit referenced below,
but the order of ifdefs was not the usual one (newest up top), which
might have caused this to slip through.
this fixes a regression when using zvols as Qemu block devices, but
might have broken other use cases as well. the symptoms are that all
sync writes from within a VM configured to use such a virtual block
devices are ignored and treated as async writes by the host ZFS layer.
this can be verified using fio in sync mode inside the VM, for example
with
fio \
--filename=/dev/sda --ioengine=libaio --loops=1 --size=10G \
--time_based --runtime=60 --group_reporting --stonewall --name=cc1 \
--description="CC1" --rw=write --bs=4k --direct=1 --iodepth=1 \
--numjobs=1 --sync=1
which shows an IOPS number way above what the physical device underneath
supports, with "zpool iostat -r 1" on the hypervisor side showing no
sync IO occuring during the benchmark.
with the regression fixed, both fio inside the VM and the IO stats on
the host show the expected numbers.

Many tests use mktemp to create temporary files and dirs, which will
usually put them in /tmp unless instructed otherwise. This had led to
many tests trying to give mktemp a useful temp path in ad-hoc ways, and
others just using it directly without knowing they're potentially
leaving stuff lying around.
So we set TMPDIR to FILEDIR, which makes the simplest uses of mktemp put
things in the wanted work dir.
Included here is a hack to get TMPDIR into the test. If a test has to be
run as a different user (most of them), it is run through sudo. ld.so
from glibc will not pass TMPDIR to a setuid program, so instead we
re-set TMPDIR after sudo before running the target command.

Further, if test groups or individual tests themselves specificed an

it is certainly not consistent with the rest.
To clean all this up, change things to append a timestamp to a received

dropdown menu in the Github runners tab with two options:
Build RPMs - Build release RPMs and tarballs and put them into an
artifact ZIP file. The directory structure used in
the ZIP file mirrors the ZFS yum repo.
Test repo - Test install the ZFS RPMs from the ZFS repo. On
Almalinux, this will do a DKMS and KMOD test install
from both the regular and testing repos. On Fedora,
it will do a DKMS install from the regular repo. All
test install results will be displayed in the Github
runner Summary page. Note that the workflow provides an
optional text box where you can specify the full URL to
an alternate repo. If left blank, it will install from
the default repo from the zfs-release RPM.

to be used by the ZFS admins for building and testing releases.

Before this change zfs_metaslab_switch_threshold tunable switched
metaslabs each time ones index reduced by two (which means biggest
contiguous chunk reduced to 1/4). It is a good idea to balance
metaslabs fragmentation. But for empty metaslabs (having power-
of-2 sizes) this means switching when they get just below the half
of their capacity. Inspection with zdb after filling new pool to
half capacity shown most of its metaslabs filled to half capacity.
I consider this sub-optimal for pool fragmentation in a long run.
This change blocks the metaslabs switching if most of the metaslab
free space (15/16) is represented by a single contiguous range.
Such metaslab should not be considered fragmented until it actually
fail some big allocation. More contiguous filling should improve
data locality and increase time before previously filled and
partially freed metaslab is touched again, giving it more time to
free more contiguous chunks for lower fragmentation. It should
also slightly reduce spacemap traffic.

zfs_file_fsync() and zfs_file_deallocate() are both blocking ops, so the
zio_taskq thread is active and blocked both while waiting for the IO

particular issue for FLUSH, as the z_flush_iss queue typically only has
one thread; multiple flushes arriving at once can cause long delays if
the underlying fsync() response is particularly slow.
To fix this, we dispatch both FLUSH and TRIM to the z_vdev_file taskq,
just as we do for reads and writes. Further, we return all results
through zio_interrupt(), so neither the issue nor the file taskqs are
blocked.

recv_fix_encryption_hierarchy() in its present state goes through all
stream filesystems, and for each one traverses the snapshots in order to
find one that exists locally. This happens by calling guid_to_name() for
each snapshot, which iterates through all children of the filesystem.
This results in CPU utilization of 100% for several minutes (for ~1000
filesystems on a Ryzen 4350G) for 1 thread at the end of a raw receive
(-w, regardless whether encrypted or not, dryrun or not).
Fix this by following a different logic: using the top_fs name, call
gather_nvlist() to gather the nvlists for all local filesystems. For
each one filesystem, go through the snapshots to find the corresponding
stream's filesystem (since we know the snapshots guid and can search
with it in stream_avl for the stream's fs). Then go on to fix the
encryption roots and locations as in its present state.
Avoiding guid_to_name() iteratively makes
recv_fix_encryption_hierarchy() significantly faster (from several
minutes to seconds for ~1000 filesystems on a Ryzen 4350G).
Another problem is the following: in case we have promoted a clone of
the filesystem outside the top filesystem specified in zfs send, zfs
receive does not fail but returns an error:
recv_incremental_replication() fails to find its origin and errors out
with needagain=1. This results in recv_fix_hierarchy() not being called
which may render some children of the top fs not mountable since their
encryption root was not updated. To circumvent this make
recv_incremental_replication() silently ignore this error.

When you are using large recordsizes in conjunction with raidz, with
incompressible data, you can pretty reliably be making 21 MB
allocations. Unfortunately, the fragmentation metric in ZFS considers
any metaslabs with 16 MB free chunks completely unfragmented, so you can
have a metaslab report 0% fragmented and be unable to satisfy an
allocation. When using the segment-based metaslab weight, this is
inconvenient; when using the space-based one, it can seriously degrade
performance.
We expand the fragmentation table to extend up to 512MB, and redefine
the table size based on the actual table, rather than having a static
define. We also tweak the one variable that depends on fragmentation
directly.

This is a convenience for filesystems that need the inode of their
parent or their own name, as its often complicated to get that
information. We don't need those things, so this is just detecting which
prototype is expected and adjusting our callback to match.

As zios are reexecuted after resume from suspension, their ready and
wait states need to be propagated to wait counts on all their parents.
It's possible for those parents to have active children passing through
READY or DONE, which then end up in zio_notify_parent(), take their
parent's lock, and decrement the wait count. Without also taking a lock
here, it's possible for an increment race to occur, which leads to
either there being no references left (tripping the assert in
zio_notify_parent()), or a parent waiting forever for a nonexistent
child to complete.
To protect against this, we simply take the appropriate zio locks in
zio_reexecute() before updating the wait counts.

Originally #16856 updated Linux Direct I/O requests to use the new
pin_user_pages API. However, it was an oversight that this PR only
handled iov_iter's of type ITER_IOVEC and ITER_UBUF. Other iov_iter
types may try and use the pin_user_pages API if it is available. This
can lead to panics as the iov_iter is not being iterated over correctly
in zfs_uio_pin_user_pages().
Unfortunately, generic iov_iter API's that call pin_user_page_fast() are
protected as GPL only. Rather than update zfs_uio_pin_user_pages() to
account for all iov_iter types, we can simply just call
zfs_uio_get_dio_page_iov_iter() if the iov_iter type is not ITER_IOVEC
or ITER_UBUF. zfs_uio_get_dio_page_iov_iter() calls the
iov_iter_get_pages() calls that can handle any iov_iter type.
In the future it might be worth using the exposed iov_iter iterator
functions that are included in the header iov_iter.h since v6.7. These
functions allow for any iov_iter type to be iterated over and advanced
while applying a step function during iteration. This could possibly be
leveraged in zfs_uio_pin_user_pages().
A new ZFS test case was added to test that a ITER_BVEC is handled
correctly using this new code path. This test case was provided though
issue #16956.

Injecting a device probe failure is not possible by matching IO types,
because probe IO goes to the label regions, which is explicitly excluded
from injection. Even if it were possible, it would be awkward to do,
because a probe is sequence of reads and writes.
This commit adds a new IO "type" to match for injection, which looks for
the ZIO_FLAG_PROBE flag instead. Any probe IO will be match the

zfs_arc_shrinker_limit was introduced to avoid ARC collapse due to
aggressive kernel reclaim. While useful, the current default (10000) is
too prone to OOM especially when MGLRU-enabled kernels with default
min_ttl_ms are used. Even when no OOM happens, it often causes too much
swap usage.
This patch sets zfs_arc_shrinker_limit=0 to not ignore kernel reclaim
requests. ARC now plays better with both kernel shrinker and pagecache
but, should ARC collapse happen again, MGLRU behavior can be tuned or
even disabled.
Anyway, zfs should not cause OOM when ARC can be released.

In Linux, block devices currently lack support for `copy_file_range`

We have adopted this upstream kernel patch into the TrueNAS kernel and
made some additional modifications to enable block cloning specifically
for the zvol block device. This patch implements the platform-
independent portions of these changes for inclusion in OpenZFS.
This patch does not introduce any new functionality directly into
OpenZFS. The `TX_CLONE_RANGE` replay capability is only relevant when
zvols are migrated to non-TrueNAS systems that support Clone Range

Closes#16862
In dbuf_sync_leaf, we clone the arc_buf in dr if we share it with db
except for overridden case. However, this exception causes a race where
dbuf_new_size could free the arc_buf after the last dereference of
*datap and causes use-after-free. We fix this by cloning the buf
regardless if it's overridden.
The race:
--
P0 P1
dbuf_hold_impl()
// dbuf_hold_copy passed
// because db_data_pending NULL
dbuf_sync_leaf()
// doesn't clone *datap
// *datap derefed to db_buf
dbuf_write(*datap)

dbuf_fix_old_data()
// alloc new buf for P0 dr
// but can't change *datap

arc_buf_destroy()
// alloc new buf for db_buf
// and destroy old buf
dbuf_write() // continue
abd_get_from_buf(data->b_data,
arc_buf_size(data))
// use-after-free

- Instead of copying one ashift-sized block per ZIO, copy as much
as we have contiguous data up to 16MB per old vdev. To avoid data
moves use gang ABDs, so that read ZIOs can directly fill buffers
for write ZIOs. ABDs have much smaller overhead than ZIOs in both
memory usage and processing time, plus big I/Os do not depend on
I/O aggregation and scheduling to reach decent performance on HDDs.
- Reduce raidz_expand_max_copy_bytes to 16MB on 32bit platforms.
- Use 32bit range tree when possible (practically always now) to
slightly reduce memory usage.
- Use ZIO_PRIORITY_REMOVAL for early stages of expansion, same as

When replacing a disk, a child process is forked to run a script called
zfs_prepare_disk (which can be useful for disk firmware update or health
check). The parent than calls waitpid and checks the child error/status
code.
However, the _reap_children thread (created from zed_exec_process to
manage zedlets) also waits for all children with the same PGID and can
stole the signal, causing the replace operation to be aborted.
As waitpid returns -1, the parent incorrectly assume that the child
process had an error or was killed. This, in turn, leaves the newly
added disk in REMOVED or UNAVAIL status rather than completing the
replace process.
This patch changes the PGID of the child process execuing the
prepare script, shielding it from the _reap_children thread.

- With both pending and current AVL-trees being per-vdev and having
effectively identical comparison functions (pending tree compared
also birth time, but I don't believe it is possible for them to be
different for the same offset within one transaction group), it
makes no sense to move entries from one to another. Instead inline
dramatically simplified brt_entry_addref() into brt_pending_apply().
It no longer requires bv_lock, since there is nothing concurrent
to it at the time. And it does not need to search the tree for the
previous entries, since it is the same tree, we already have the
entry and we know it is unique.
- Put brt_vdev_lookup() and brt_vdev_addref() into different tree
traversals to avoid false positives in the first due to the second
entcount modifications. It saves dramatic amount of time when a
file cloned first time by not looking for non-existent ZAP entries.
- Remove avl_is_empty(bv_tree) check from brt_maybe_exists(). I
don't think it is needed, since by the time all added entries are
already accounted in bv_entcount. The extra check must be producing
too many false positives for no reason. Also we don't need bv_lock
there, since bv_entcount pointer must be table at this point, and
we don't care about false positive races here, while false negative
should be impossible, since all brt_vdev_addref() have already
completed by this point. This dramatically reduces lock contention
on massive deletes of cloned blocks. The only remaining one is
between multiple parallel free threads calling brt_entry_decref().
- Do not update ZAP if net change for a block over the TXG was 0.
In combination with above it makes file move between datasets as
cheap operation as originally intended if it fits into one TXG.
- Do not allocate vdevs on pool creation or import if it did not
have active block cloning. This allows to save a bit in few cases.
- While here, add proper error handling in brt_load() on pool
import instead of assertions.

While block cloning operation from the beginning was made per-vdev,
before this change most of its data were protected by two pool-
wide locks. It created lots of lock contention in many workload.
This change makes most of block cloning data structures per-vdev,
which allows to lock them separately. The only pool-wide lock now
it spa_brt_lock, protecting array of per-vdev pointers and in most
cases taken as reader. Also this splits per-vdev locks into three
different ones: bv_pending_lock protects the AVL-tree of pending
operations in open context, bv_mos_entries_lock protects BRT ZAP
object from while being prefetched, and bv_lock protects the rest
of per-vdev context during TXG commit process. There should be
no functional difference aside of some optimizations.

dsl_free() calls zio_free() to free the block. For most blocks, this
simply calls metaslab_free() without doing any IO or putting anything on
the IO pipeline.
Some blocks however require additional IO to free. This at least
includes gang, dedup and cloned blocks. For those, zio_free() will issue
a ZIO_TYPE_FREE IO and return.
If a huge number of blocks are being freed all at once, it's possible
for dsl_dataset_block_kill() to be called millions of time on a single
transaction (eg a 2T object of 128K blocks is 16M blocks). If those are
all IO-inducing frees, that then becomes 16M FREE IOs placed on the
pipeline. At time of writing, a zio_t is 1280 bytes, so for just one 2T
object that requires a 20G allocation of resident memory from the
zio_cache. If that can't be satisfied by the kernel, an out-of-memory
condition is raised.
This would be better handled by improving the cases that the
dmu_tx_assign() throttle will handle, or by reducing the overheads
required by the IO pipeline, or with a better central facility for
freeing blocks.
For now, we simply check for the cases that would cause zio_free() to
create a FREE IO, and instead put the block on the pool's freelist. This
is the same place that blocks from destroyed datasets go, and the async
destroy machinery will automatically see them and trickle them out as
normal.

As a deadlock avoidance measure, zfs_getpages() would only try to
acquire a rangelock, falling back to a single-page read if this was not
possible. However, this is incompatible with direct I/O.
Instead, release the busy lock before trying to acquire the rangelock in
blocking mode. This means that it's possible for the page to be
replaced, so we have to re-lookup.

In zpool_get_user_prop, when called from zpool_expand_proplist and
collect_pool, we often have zpool_props present in zpool_handle_t equal
to NULL. This mostly happens when only one user property is requested
using zpool list -o <user_property>. Checking for this case and
correctly initializing the zpool_props field in zpool_handle_t fixes
this issue.
Interestingly, this issue does not occur if we query any other property
like name or guid along with a user property with -o flag because while
accessing properties like guid, zpool_prop_get_int is called which
checks for this case specifically and calls zpool_get_all_props.

Introduction of specialized kmem cache allows to reduce the size

in dirty records are mutually exclusive, puting them into a union
allows to reduce structure size down to 368 bytes, increasing the

It seems out our notion of "properly" aligned IO was incomplete. In
particular, dm-crypt does its own splitting, and assumes that a logical
block will never cross an order-0 page boundary (ie, the physical page
size, not compound size). This effectively means that it needs to be
possible to split a BIO at any page or block size boundary and have it
work correctly.
This updates the alignment check function to enforce these rules (to the
extent possible).
Our response to misaligned data is to make some new allocation that is
properly aligned, and copy the data into it. It turns out that
linearising (via abd_borrow_buf()) is not enough, because we allocate eg
4K blocks from a general purpose slab, and so may receive (or already
have) a 4K block that crosses pages.
So instead, we allocate a new ABD, which is guaranteed to be aligned
properly to block sizes, and then copy everything into it, and back out
on the way back.

All of our thread entry functions have this signature:
void (*)(void*) __attribute__((noreturn))
The low-level `__thread_create()` function accepts a `thread_func_t` as
the entry point, which is defined more simply as:
void (*)(void *)
And then the `thread_create()` and `thread_create_named()` macros cast
the passed-in function point down to `thread_func_t`, that is, casting
away the `noreturn` attribute.
Clang considers casting between these two types to be invalid because
both the caller and the callee may have elided parts of the stack frame
save and restore, knowing that they won't be needed.
Recent Linux appears to be setting `-Wcast-function-type-strict`, which
causes this invalid cast to emit a warning, which with `-Werror` is
converted to an error, breaking the build.
This commit fixes this in the simplest possible way: adding `noreturn`
to the `thread_func_t` attribute. Since all our thread entry functions
already have this attribute, it's arguably a just a consistency fix
anyway.
I considered removing the casts in the macros, which silences the
warnings, but it turns out that Clang has a bug that won't emit this
error for implicit conversions, only explicit casts. So leaving them
there seems like a reasonable belt-and-suspenders approach. Also,
frankly, this whole mechanism seems a little undercooked inside LLVM, so
I'm content go with my intuition about the smallest, least invaisve
change.
**NOTE**: `__thread_create` is exported by `spl.ko` and has a
`thread_func_t` arg, so this is an ABI break. Whether that matters in
practice, I have no idea.

Before 4.20, kernel_siginfo_t was just called siginfo_t. This was
causing the kthread_dequeue_signal_3arg_task check, which uses
kernel_siginfo_t, to fail on older kernels.
In d6b8c17f1, we started checking for the "new" three-arg
dequeue_signal() by testing for the "old" version. Because that test is
explicitly using kernel_siginfo_t, it would fail, leading to the build
trying to use the new three-arg version, which would then not compile.
This commit fixes that by avoiding checking for the old 3-arg
dequeue_signal entirely. Instead, we check for the new one, as well as
the 4-arg form, and we use the old form as a fallback. This way, we
never have to test for it explicitly, and once we're building
HAVE_SIGINFO will make sure we get the right kernel_siginfo_t for it, so
everything works out nice.

While mounting ZFS root during boot on Linux distributions from initrd,
mount from busybox is effectively used which executes mount system call
directly. This skips the ZFS helper mount.zfs, which checks and enables
the mount options as specified in dataset properties. As a result,
datasets mounted during boot from initrd do not have correct mount
options as specified in ZFS dataset properties.
There has been an attempt to use mount.zfs in zfs initrd script,
responsible for mounting the ZFS root filesystem (PR#13305). This was
later reverted (PR#14908) after discovering that using mount.zfs breaks
mounting of snapshots on root (/) and other child datasets of root have
the same issue (Issue#9461).
This happens because switching from busybox mount to mount.zfs correctly
parses the mount options but also adds 'mntpoint=/root' to the mount
options, which is then prepended to the snapshot mountpoint in
'.zfs/snapshot'. '/root' is the directory on Debian with initramfs-tools
where root filesystem is mounted before pivot_root. When Linux runtime
is reached, trying to access the snapshots on root results in
automounting the snapshot on '/root/.zfs/*', which fails.
This commit attempts to fix the automounting of snapshots on root, while
using mount.zfs in initrd script. Since the mountpoint of dataset is
stored in vfs_mntpoint field, we can check if current mountpoint of
dataset and vfs_mntpoint are same or not. If they are not same, reset
the vfs_mntpoint field with current mountpoint. This fixes the
mountpoints of root dataset and children in respective vfs_mntpoint
fields when we try to access the snapshots of root dataset or its
children. With correct mountpoint for root dataset and children stored
in vfs_mntpoint, all snapshots of root dataset are mounted correctly
and become accessible.
This fix will come into play only if current process, that is trying to
access the snapshots is not in chroot context. The Linux kernel API
that is used to convert struct path into char format (d_path), returns
the complete path for given struct path. It works in chroot environment
as well and returns the correct path from original filesystem root.
However d_path fails to return the complete path if any directory from
original root filesystem is mounted using --bind flag or --rbind flag
in chroot environment. In this case, if we try to access the snapshot
from outside the chroot environment, d_path returns the path correctly,
i.e. it returns the correct path to the directory that is mounted with
--bind flag. However inside the chroot environment, it only returns the
path inside chroot.
For now, there is not a better way in my understanding that gives the
complete path in char format and handles the case where directories from
root filesystem are mounted with --bind or --rbind on another path which
user will later chroot into. So this fix gets enabled if current
process trying to access the snapshot is not in chroot context.
With the snapshots issue fixed for root filesystem, using mount.zfs in
ZFS initrd script, mounts the datasets with correct mount options.

times. This is sufficient to verify parallel imports are working as
intended and should address the occasional false positive failure
when the time is slightly exceeded.

Mostly so that with the JSON formatting options are also used, they all

different or unrelated, while `--json --json-flat-vdevs` invites no
further questions.

This fixes an oversight in the Direct I/O PR. There is nothing that
stops a process from manipulating the contents of a buffer for a
Direct I/O read while the I/O is in flight. This can lead checksum
verify failures. However, the disk contents are still correct, and this
would lead to false reporting of checksum validation failures.
To remedy this, all Direct I/O reads that have a checksum verification
failure are treated as suspicious. In the event a checksum validation
failure occurs for a Direct I/O read, then the I/O request will be
reissued though the ARC. This allows for actual validation to happen and
removes any possibility of the buffer being manipulated after the I/O
has been issued.
Just as with Direct I/O write checksum validation failures, Direct I/O
read checksum validation failures are reported though zpool status -d in
the DIO column. Also the zevent has been updated to have both:
1. dio_verify_wr -> Checksum verification failure for writes
2. dio_verify_rd -> Checksum verification failure for reads.
This allows for determining what I/O operation was the culprit for the
checksum verification failure. All DIO errors are reported only on the
top-level VDEV.
Even though FreeBSD can write protect pages (stable pages) it still has
the same issue as Linux with Direct I/O reads.
This commit updates the following:
1. Propogates checksum failures for reads all the way up to the
top-level VDEV.
2. Reports errors through zpool status -d as DIO.
3. Has two zevents for checksum verify errors with Direct I/O. One for
read and one for write.
4. Updates FreeBSD ABD code to also check for ABD_FLAG_FROM_PAGES and
handle ABD buffer contents validation the same as Linux.
5. Updated manipulate_user_buffer.c to also manipulate a buffer while a
Direct I/O read is taking place.
6. Adds a new ZTS test case dio_read_verify that stress tests the new
code.
7. Updated man pages.
8. Added an IMPLY statement to zio_checksum_verify() to make sure that
Direct I/O reads are not issued as speculative.
9. Removed self healing through mirror, raidz, and dRAID VDEVs for
Direct I/O reads.
This issue was first observed when installing a Windows 11 VM on a ZFS
dataset with the dataset property direct set to always. The zpool
devices would report checksum failures, but running a subsequent zpool
scrub would not repair any data and report no errors.
