Update the GitHub actions workflows using a subset of the changes
from the master branch, commit 620a977f22. Cherry-picking each
relevant commit would have resulted in a large number of conflicts
so this change only applies a minimal set of useful updates.
- Added build-dependencies.txt and checkstyle-dependencies.txt
- Added reclaim_disk_space.sh script
- Minor changes to build steps
- Reduced ztest run time
- checkbashisms, mandoc, and cppcheck were not included to
avoid additional backports
- Add exceptions for shellcheck

The default_bs and default_ibs tunables control the default block size
and indirect block size.
So far, default_bs and default_ibs were tunable only on FreeBSD, e.g.,
sysctl vfs.zfs.default_ibs
Remove the FreeBSD-specific sysctl code and expose default_bs and
default_ibs as tunables on both Linux and FreeBSD using
ZFS_MODULE_PARAM.
One of the use cases for changing the values of those tunables is to
lower the indirect block size, which may improve performance of large
directories (as discussed during the OpenZFS Leadership Meeting
on 2022-08-16).

dc5c8006f6 was recently merged to prefetch
up to 128 deadlists. Unfortunately, a loop was missing an increment,
such that it will prefetch all deadlists. The performance properties of
that patch probably should be re-evaluated.
This was caught by CodeQL's cpp/constant-comparison check in an
experimental branch where I am testing the security-and-extended
queries. It complained about the `i < 128` part of the loop condition
always evaluating to the same thing. The standard CodeQL configuration
we use missed this because it does not include that check.

With some pathological access patterns it is possible to make ZFS
accumulate almost unlimited amount of speculative prefetch ZIOs.
Combined with linear ABD allocations in RAIDZ code, it appears to
be possible to exhaust system KVA, triggering kernel panic.
Address this by introducing a system-wide counter of active prefetch
requests and blocking prefetch distance doubling per stream hits if
the number of active requests is higher that ~6% of ARC size.

During snapshot deletion ZFS may issue several reads for each deadlist
to merge them into next snapshot's or pool's bpobj. Number of the dead
lists increases with number of snapshots. On HDD pools it may take

This patch introduces prescient prefetch of required blocks for up to
128 deadlists ahead. Tests show reduction of time required to delete

Issue #14276Closes#14402
Despite all optimizations, tests on actual hardware show that FreeBSD
kernel can't sleep for less then ~2us. Similar tests on Linux show
~50us delay at least from nanosleep() (haven't tested inside kernel).
It means that on very fast log device ZIL may not be able to satisfy
zfs_commit_timeout_pct block commit timeout, increasing log latency
more than desired.
Handle that by introduction of zil_min_commit_timeout parameter,
specifying minimal timeout value where additional delays to aggregate
writes may be skipped. Also skip delays if the LWB is more than 7/8
full, that often happens if I/O sizes are constant and match one of
LWB sizes. Both things are applied only if there were no already
outstanding log blocks, that may indicate single-threaded workload,
that by definition can not benefit from the commit delays.
While there, add short time moving average to zl_last_lwb_latency to
make it more stable.
Tests of single-threaded 4KB writes to NVDIMM SLOG on FreeBSD show IOPS
increase by 9% instead of expected 5%. For zfs_commit_timeout_pct of
1 there IOPS increase by 5.5% instead of expected 1%.

Microzap on-disk format does not include a hash tree, expecting one to
be built in RAM during mzap_open(). The built tree is linked to DMU
user buffer, freed when original DMU buffer is dropped from cache. I've
found that workloads accessing many large directories and having active
eviction from DMU cache spend significant amount of time building and
then destroying the trees. I've also found that for each 64 byte mzap
element additional 64 byte tree element is allocated, that is a waste
of memory and CPU caches.
Improve memory efficiency of the hash tree by switching from AVL-tree
to B-tree. It allows to save 24 bytes per element just on pointers.
Save 32 bits on mze_hash by storing only upper 32 bits since lower 32
bits are always zero for microzaps. Save 16 bits on mze_chunkid, since
microzap can never have so many elements. Respectively with the 16 bits
there can be no more than 16 bits of collision differentiators. As
result, struct mzap_ent now drops from 48 (rounded to 64) to 8 bytes.
Tune B-trees for small data. Reduce BTREE_CORE_ELEMS from 128 to 126
to allow struct zfs_btree_core in case of 8 byte elements to pack into
2KB instead of 4KB. Aside of the microzaps it should also help 32bit
range trees. Allow custom B-tree leaf size to reduce memmove() time.
Split zap_name_alloc() into zap_name_alloc() and zap_name_init_str().
It allows to not waste time allocating/freeing memory when processing
multiple names in a loop during mzap_open().
Together on a pool with 10K directories of 1800 files each and DMU
cache limited to 128MB this reduces time of `find . -name zzz` by 41%
from 7.63s to 4.47s, and saves additional ~30% of CPU time on the DMU
cache reclamation.

d_alias may need to be converted to du.d_alias

to
"hlist_for_each_entry(dentry, &inode->i_dentry, d_u.d_alias)"

This effectively results in a double macro expansion
for code that uses the zfs headers but already has its
own macro for just d_alias (lustre in this case).

Illumos-issue: https://www.illumos.org/issues/15286
Illumos-commit: f137b22e73
Porting Notes:
The patch in illumos did not have much of a commit message, and did not
provide attribution to the reporter, while original patch proposed to
OpenZFS did, so I am listing the reporter (myself) and original patch
author (also myself) below while including the original commit message
with some minor corrections as part of the porting notes:
In do_composition(), we have:
size = u8_number_of_bytes[*p];
if (size <= 1 || (p + size) > oslast)
break;
There, we have type promotion from int8_t to size_t, which is unsigned.
C will sign extend the value as part of the widening before treating the
value as unsigned and the negative values we can counter are error
values from U8_ILLEGAL_CHAR and U8_OUT_OF_RANGE_CHAR, which are -1 and
-2 respectively. The unsigned versions of these under two's complement
are SIZE_MAX and SIZE_MAX-1 respectively.
The bounds check is written under the assumption that `size <= 1` does a
signed comparison. This is followed by a pointer comparison to see if
the string has the correct length, which is fine.
A little further down we have:
for (i = 0; i < size; i++)
tc[i] = *p++;
When an error condition is encountered, this will attempt to iterate at
least SIZE_MAX-1 times, which will massively overflow the buffer, which
is not fine.
The kernel will kill the loop as soon as it hits the kernel stack guard
on Linux systems built with CONFIG_VMAP_STACK=y, which should be just
about all of them. That prevents arbitrary code execution and just about
any other bad thing that a black hat attacker might attempt with
knowledge of this buffer overflow. Other systems' kernels have
mitigations for unbounded in-kernel buffer overflows that will catch
this too.
Also, the patch in illumos-gate made an effort to fix C style issues
that had been fixed in the OpenZFS/ZFSOnLinux repository. Those issues
had been mentioned in the email that I originally sent them about this
issue. One of the fixes had not been already done, so it is included.
Another to collect_a_seq()'s arguments was handled differently in
OpenZFS. For the sake of avoiding unnecessary differences, it has been
adopted. This has the interesting effect that if you correct the paths
in the illumos-gate patch to match the current OpenZFS repository, you
can reverse apply it cleanly.
