- show detailed results for each system
- in the end, generate the job summary
Real-world benefits from this PR:
1. The github runner scripts are in the zfs repo itself. That means
you can just open a PR against zfs, like "Add Fedora 41 tester", and
see the results directly in the PR. ZFS admins no longer need
manually to login to the buildbot server to update the buildbot config
with new version of Fedora/Almalinux.
2. Github runners allow you to run the entire test suite against your
private branch before submitting a formal PR to openzfs. Just open a
PR against your private zfs repo, and the exact same
Fedora/Alma/FreeBSD runners will fire up and run ZTS. This can be
useful if you want to iterate on a ZTS change before submitting a
formal PR.
3. buildbot is incredibly cumbersome. Our buildbot config files alone
are ~1500 lines (not including any build/setup scripts)!
It's a huge pain to setup.
4. We're running the super ancient buildbot 0.8.12. It's so ancient
it requires python2. We actually have to build python2 from source
for almalinux9 just to get it to run. Ugrading to a more modern
buildbot is a huge undertaking, and the UI on the newer versions is
worse.
5. Buildbot uses EC2 instances. EC2 is a pain because:
* It costs money
* They throttle IOPS and CPU usage, leading to mysterious,
* hard-to-diagnose, failures and timeouts in ZTS.
* EC2 is high maintenance. We have to setup security groups, SSH
* keys, networking, users, etc, in AWS and it's a pain. We also
* have to periodically go in an kill zombie EC2 instances that
* buildbot is unable to kill off.
6. Buildbot doesn't always handle failures well. One of the things we
saw in the past was the FreeBSD builders would often die, and each
builder death would take up a "slot" in buildbot. So we would
periodically have to restart buildbot via a cron job to get the slots
back.
7. This PR divides up the ZTS test list into two parts, launches two
VMs, and on each VM runs half the test suite. The test results are
then merged and shown in the sumary page. So we're basically
parallelizing ZTS on the same github runner. This leads to lower
overall ZTS runtimes (2.5-3 hours vs 4+ hours on buildbot), and one
unified set of results per runner, which is nice.
8. Since the tests are running on a VM, we have much more control over
what happens. We can capture the serial console output even if the
test completely brings down the VM. In the future, we could also
restart the test on the VM where it left off, so that if a single test
panics the VM, we can just restart it and run the remaining ZTS tests
(this functionaly is not yet implemented though, just an idea).
9. Using the runners, users can manually kill or restart a test run
via the github IU. That really isn't possible with buildbot unless
you're an admin.
10. Anecdotally, the tests seem to be more stable and constant under
the QEMU runners.

Closes#16537
Adding O_DIRECT support to ZFS to bypass the ARC for writes/reads.
O_DIRECT support in ZFS will always ensure there is coherency between
buffered and O_DIRECT IO requests. This ensures that all IO requests,
whether buffered or direct, will see the same file contents at all
times. Just as in other FS's , O_DIRECT does not imply O_SYNC. While
data is written directly to VDEV disks, metadata will not be synced
until the associated TXG is synced.
For both O_DIRECT read and write request the offset and request sizes,
at a minimum, must be PAGE_SIZE aligned. In the event they are not,
then EINVAL is returned unless the direct property is set to always (see
below).
For O_DIRECT writes:
The request also must be block aligned (recordsize) or the write
request will take the normal (buffered) write path. In the event that
request is block aligned and a cached copy of the buffer in the ARC,
then it will be discarded from the ARC forcing all further reads to
retrieve the data from disk.
For O_DIRECT reads:
The only alignment restrictions are PAGE_SIZE alignment. In the event
that the requested data is in buffered (in the ARC) it will just be
copied from the ARC into the user buffer.
For both O_DIRECT writes and reads the O_DIRECT flag will be ignored in
the event that file contents are mmap'ed. In this case, all requests
that are at least PAGE_SIZE aligned will just fall back to the buffered
paths. If the request however is not PAGE_SIZE aligned, EINVAL will
be returned as always regardless if the file's contents are mmap'ed.
Since O_DIRECT writes go through the normal ZIO pipeline, the
following operations are supported just as with normal buffered writes:
Checksum
Compression
Encryption
Erasure Coding
There is one caveat for the data integrity of O_DIRECT writes that is
distinct for each of the OS's supported by ZFS.
FreeBSD - FreeBSD is able to place user pages under write protection so
any data in the user buffers and written directly down to the
VDEV disks is guaranteed to not change. There is no concern
with data integrity and O_DIRECT writes.
Linux - Linux is not able to place anonymous user pages under write
protection. Because of this, if the user decides to manipulate
the page contents while the write operation is occurring, data
integrity can not be guaranteed. However, there is a module
parameter `zfs_vdev_direct_write_verify` that controls the
if a O_DIRECT writes that can occur to a top-level VDEV before
a checksum verify is run before the contents of the I/O buffer
are committed to disk. In the event of a checksum verification
failure the write will return EIO. The number of O_DIRECT write
checksum verification errors can be observed by doing
`zpool status -d`, which will list all verification errors that
have occurred on a top-level VDEV. Along with `zpool status`, a
ZED event will be issues as `dio_verify` when a checksum
verification error occurs.
ZVOLs and dedup is not currently supported with Direct I/O.
A new dataset property `direct` has been added with the following 3
allowable values:
disabled - Accepts O_DIRECT flag, but silently ignores it and treats
the request as a buffered IO request.
standard - Follows the alignment restrictions outlined above for
write/read IO requests when the O_DIRECT flag is used.
always - Treats every write/read IO request as though it passed
O_DIRECT and will do O_DIRECT if the alignment restrictions
are met otherwise will redirect through the ARC. This
property will not allow a request to fail.
There is also a module parameter zfs_dio_enabled that can be used to
force all reads and writes through the ARC. By setting this module
parameter to 0, it mimics as if the direct dataset property is set to
disabled.

The dedup log does not have a stable cursor, so its not possible to
persist our current scan location within it across pool reloads.
Beccause of this, when walking (scanning), we can't treat it like just
another source of dedup entries.
Instead, when a scan is wanted, we switch to an aggressive flushing
mode, pushing out entries older than the scan start txg as fast as we
can, before starting the scan proper.
Entries after the scan start txg will be handled via other methods; the
DDT ZAPs and logs will be written as normal, and blocks not seen yet
will be offered to the scan machinery as normal.

Adds a log/journal to dedup. At the end of txg, instead of writing the
entry directly to the ZAP, instead its adding to an in-memory tree and
appended to an on-disk object. The on-disk object is only read at
import, to reload the in-memory tree.
Lookups first go the the log tree before going to the ZAP, so
recently-used entries will remain close by in memory. This vastly
reduces overhead from dedup IO, as it will not have to do so many
read/update/write cycles on ZAP leaf nodes.
A flushing facility is added at end of txg, to push logged entries out
to the ZAP. There's actually two separate "logs" (in-memory tree and
on-disk object), one active (recieving updated entries) and one flushing
(writing out to disk). These are swapped (ie flushing begins) based on
memory used by the in-memory log trees and time since we last flushed
something.
The flushing facility monitors the amount of entries coming in and being
flushed out, and calibrates itself to try to flush enough each txg to
keep up with the ingest rate without competing too much with other IO.
Multiple tuneables are provided to control the flushing facility.
All the histograms and stats are update to accomodate the log as a
separate entry store. zdb gains knowledge of how to count them and dump
them. Documentation included!

This is the supporting infrastructure for the upcoming dedup features.
Traditionally, dedup objects live directly in the MOS root. While their
details vary (checksum, type and class), they are all the same "kind" of
thing - a store of dedup entries.
The new features are more varied than that, and are better thought of as
a set of related stores for the overall state of a dedup table.
This adds a new feature flag, SPA_FEATURE_FAST_DEDUP. Enabling this will
cause new DDTs to be created as a ZAP in the MOS root, named
DDT-<checksum>. The is used as the root object for the normal type/class
store objects, but will also be a place for any storage required by new
features.
This commit adds two new fields to ddt_t, for version and flags. These
are intended to describe the structure and features of the overall dedup
table, and are stored as-is in the DDT root. In this commit, flags are
always zero, but the intent is that they can be used to hang optional
logic or state onto for new dedup features. Version is always 1.
For a "legacy" dedup table, where no DDT root directory exists, the
version will be 0.
ddt_configure() is expected to determine the version and flags features
currently in operation based on whether or not the fast_dedup feature is
enabled, and from what's available on disk. In this way, its possible to
support both old and new tables.
This also provides a migration path. A legacy setup can be upgraded to
FDT by creating the DDT root ZAP, moving the existing objects into it,
and setting version and flags appropriately. There's no support for that
here, but it would be straightforward to add later and allows the
possibility that newer features could be applied to existing dedup
tables.

So far, the values of ZFS_MAXPROPLEN and ZPOOL_MAXPROPLEN were equal to
MAXPATHLEN, which is 1024 on FreeBSD and 4096 on Linux. This wasn't
ideal. Some of the surprising outcomes of this implementation are:
1. When creating a pool user property with zpool-set(8), libzfs makes
sure that the length of the property's value is less than
ZFS_MAXPROPLEN. However, the ZFS kernel module does not do that.
Instead, it checks the length against ZAP_MAXVALUELEN. As a result,
it is possible to create a property the length of which is going to
be larger than zpool(8) is ready to read.
2. A pool user property created on Linux is too big to be read on
FreeBSD.
This change sets both ZFS_MAXPROPLEN and ZPOOL_MAXPROPLEN to
ZAP_MAXVALUELEN, which is 8192 at the moment.

This adds two new pool properties:
- dedup_table_size, the total size of all DDTs on the pool; and
- dedup_table_quota, the maximum possible size of all DDTs in the pool
When set, quota will be enforced by checking when a new entry is about
to be created. If the pool is over its dedup quota, the entry won't be
created, and the corresponding write will be converted to a regular
non-dedup write. Note that existing entries can be updated (ie their
refcounts changed), as that reuses the space rather than requiring more.
dedup_table_quota can be set to 'auto', which will set it based on the
size of the devices backing the "dedup" allocation device. This makes it
possible to limit the DDTs to the size of a dedup vdev only, such that
when the device fills, no new blocks are deduplicated.

cp_stress is getting killed on the new QEMU-based github runners
we're developing. The problem is that the Linux based runners
should do 10 RUNS, where the FreeBSD based runners only have 3
RUNS to succeed.
This patch removes this different handling of Linux and FreeBSD.
The cp_stress test is running fine in around 2 minutes now.

A single disk pool should suspend when its disk fails and hold the IO.
When the disk is returned, the pool should return and the IO be
reissued, leaving everything in good shape.

sha2_mech_type_t serves double-duty, as the list of MAC providers and
also the algo type for direct callers to SHA2Init. Until we disentangle
that, reorganise it to make the separation more clear. While we're

The test was trying to diff the file listings between two directories to
see if they are the same. The workaround is to do a string comparison
of the directory listings instead of using `diff`.

Optionally turn off disk's enclosure slot if an I/O is hung
triggering the deadman.
It's possible for outstanding I/O to a misbehaving SCSI disk to
neither promptly complete or return an error. This can occur due
to retry and recovery actions taken by the SCSI layer, driver, or
disk. When it occurs the pool will be unresponsive even though
there may be sufficient redundancy configured to proceeded without
this single disk.
When a hung I/O is detected by the kmods it will be posted as a
deadman event. By default an I/O is considered to be hung after
5 minutes. This value can be changed with the zfs_deadman_ziotime_ms
module parameter. If ZED_POWER_OFF_ENCLOSURE_SLOT_ON_DEADMAN is set
the disk's enclosure slot will be powered off causing the outstanding
I/O to fail. The ZED will then handle this like a normal disk failure.
By default ZED_POWER_OFF_ENCLOSURE_SLOT_ON_DEADMAN is not set.
As part of this change `zfs_deadman_events_per_second` is added
to control the ratelimitting of deadman events independantly of
delay events. In practice, a single deadman event is sufficient
and more aren't particularly useful.
Alphabetize the zfs_deadman_* entries in zfs.4.

Closes#16226
C99 6.7.8.17 says that when an undesignated initialiser is used, only
the first element of a union is initialised. If the first element is not
the largest within the union, how the remaining space is initialised is
up to the compiler.
GCC extends the initialiser to the entire union, while Clang treats the
remainder as padding, and so initialises according to whatever
automatic/implicit initialisation rules are currently active.
When Linux is compiled with CONFIG_INIT_STACK_ALL_PATTERN,
-ftrivial-auto-var-init=pattern is added to the kernel CFLAGS. This flag
sets the policy for automatic/implicit initialisation of variables on
the stack.
Taken together, this means that when compiling under
CONFIG_INIT_STACK_ALL_PATTERN on Clang, the "zero" initialiser will only
zero the first element in a union, and the rest will be filled with a
pattern. This is significant for aes_ctx_t, which in
aes_encrypt_atomic() and aes_decrypt_atomic() is initialised to zero,
but then used as a gcm_ctx_t, which is the fifth element in the union,
and thus gets pattern initialisation. Later, it's assumed to be zero,
resulting in a hang.
As confusing and undiscoverable as it is, by the spec, we are at fault
when we initialise a structure containing a union with the zero
initializer. As such, this commit replaces these uses with an explicit
memset(0).
