We should not hardcode 512-byte read size when checking for loader in the boot area before RAIDZ expansion. Disk might be unable to handle that I/O as is, and the code zio_vdev_io_start() handling the padding asserts doing it only for top-level vdev.

When building tests with zinject, it can be quite difficult to work out if you're producing the right kind of IO to match the rules you've set up. So, here we extend injection records to count the number of times a handler matched the operation, and how often an error was actually injected (ie after frequency and other exclusions are applied). Then, display those counts in the `zinject` output.

The old kstat helper function was barely used, I suspect in part because it was very limited in the kinds of kstats it could gather. This adds new functions to replace it, for each kind of thing that can have stats: global, pool and dataset. There's options in there to get a single stat value, or all values within a group. Most importantly, the interface is the same for both platforms. Sponsored-by: Klara, Inc. Sponsored-by: Wasabi Technology, Inc.

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 injection record and recieve the wanted error.

Originally openzfs#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 openzfs#16956.

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. Sponsored-by: Klara, Inc. Sponsored-by: Wasabi Technology, Inc.

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. Sponsored-by: Klara, Inc. Sponsored-by: Wasabi Technology, Inc.

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.

Fragmentation of full metaslabs may not matter in presence empty ones.

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 call and then while calling zio_execute() for the next stage. This is a 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. Sponsored-by: Klara, Inc. Sponsored-by: Wasabi Technology, Inc.

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.

Add a new 'zfs-qemu-packages' GH workflow for manually building RPMs
and test installing ZFS RPMs from a yum repo. The workflow has a
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.
Most developers will never need to use this workflow. It is intended
to be used by the ZFS admins for building and testing releases.
This commit also modularizes many of the runner scripts so they can
be used by both the zfs-qemu and zfs-qemu-packages workflows.
