ZED does not take any action for disk removal events if there is no
spare VDEV available. Added zpool_vdev_remove_wanted() in libzfs
and vdev_remove_wanted() in vdev.c to remove the VDEV through ZED
on removal event. This means that if you are running zed and
remove a disk, it will be properly marked as REMOVED.

Closes#13797
Coverity caught unsafe use of `strcpy()` in `ztest_dmu_objset_own()`,
`nfs_init_tmpfile()` and `dump_snapshot()`. It also caught an unsafe use
of `strlcat()` in `nfs_init_tmpfile()`.
Inspired by this, I did an audit of every single usage of `strcpy()` and
`strcat()` in the code. If I could not prove that the usage was safe, I
changed the code to use either `strlcpy()` or `strlcat()`, depending on
which function was originally used. In some cases, `snprintf()` was used
to replace multiple uses of `strcat` because it was cleaner.
Whenever I changed a function, I preferred to use `sizeof(dst)` when the
compiler is able to provide the string size via that. When it could not
because the string was passed by a caller, I checked the entire call
tree of the function to find out how big the buffer was and hard coded
it. Hardcoding is less than ideal, but it is safe unless someone shrinks
the buffer sizes being passed.
Additionally, Coverity reported three more string related issues:
* It caught a case where we do an overlapping memory copy in a call to
`snprintf()`. We fix that via `kmem_strdup()` and `kmem_strfree()`.
* It caught `sizeof (buf)` being used instead of `buflen` in
`zdb_nicenum()`'s call to `zfs_nicenum()`, which is passed to
`snprintf()`. We change that to pass `buflen`.
* It caught a theoretical unterminated string passed to `strcmp()`.
This one is likely a false positive, but we have the information
needed to do this more safely, so we change this to silence the false
positive not just in coverity, but potentially other static analysis
tools too. We switch to `strncmp()`.
* There was a false positive in tests/zfs-tests/cmd/dir_rd_update.c. We
suppress it by switching to `snprintf()` since other static analysis
tools might complain about it too. Interestingly, there is a possible
real bug there too, since it assumes that the passed directory path
ends with '/'. We add a '/' to fix that potential bug.

Closes#13913
Coverity found a bug in `zfs_secpolicy_create_clone()` where it is
possible for us to pass an unterminated string when `zfs_get_parent()`
returns an error. Upon inspection, it is clear that using `strlcpy()`
would have avoided this issue.
Looking at the codebase, there are a number of other uses of `strncpy()`
that are unsafe and even when it is used safely, switching to
`strlcpy()` would make the code more readable. Therefore, we switch all
instances where we use `strncpy()` to use `strlcpy()`.
Unfortunately, we do not portably have access to `strlcpy()` in
tests/zfs-tests/cmd/zfs_diff-socket.c because it does not link to
libspl. Modifying the appropriate Makefile.am to try to link to it
resulted in an error from the naming choice used in the file. Trying to
disable the check on the file did not work on FreeBSD because Clang
ignores `#undef` when a definition is provided by `-Dstrncpy(...)=...`.
We workaround that by explictly including the C file from libspl into
the test. This makes things build correctly everywhere.
We add a deprecation warning to `config/Rules.am` and suppress it on the
remaining `strncpy()` usage. `strlcpy()` is not portably avaliable in
tests/zfs-tests/cmd/zfs_diff-socket.c, so we use `snprintf()` there as a
substitute.
This patch does not tackle the related problem of `strcpy()`, which is
even less safe. Thankfully, a quick inspection found that it is used far
more correctly than strncpy() was used. A quick inspection did not find
any problems with `strcpy()` usage outside of zhack, but it should be
said that I only checked around 90% of them.
Lastly, some of the fields in kstat_t varied in size by 1 depending on
whether they were in userspace or in the kernel. The origin of this
discrepancy appears to be 04a479f706 where
it was made for no apparent reason. It conflicts with the comment on
KSTAT_STRLEN, so we shrink the kernel field sizes to match the userspace
field sizes.

Existing dataset is not marked INCONSISTENT. Resume of full/newfs

Coverity complained about unchecked return values and unused values that
turned out to be unused return values.
Different approaches were used to handle the different cases of
unchecked return values:
* cmd/zdb/zdb.c: VERIFY0 was used in one place since the existing code
had no error handling. An error message was printed in another to
match the rest of the code.
* cmd/zed/agents/zfs_retire.c: We dismiss the return value with `(void)`
because the value is expected to be potentially unset.
* cmd/zpool_influxdb/zpool_influxdb.c: We dismiss the return value with
`(void)` because the values are expected to be potentially unset.
* cmd/ztest.c: VERIFY0 was used since we want failures if something goes
wrong in ztest.
* module/zfs/dsl_dir.c: We dismiss the return value with `(void)`
because there is no guarantee that the zap entry will always be there.
For example, old pools imported readonly would not have it and we do
not want to fail here because of that.
* module/zfs/zfs_fm.c: `fnvlist_add_*()` was used since the
allocations sleep and thus can never fail.
* module/zfs/zvol.c: We dismiss the return value with `(void)` because
we do not need it. This matches what is already done in the analogous
`zfs_replay_write2()`.
* tests/zfs-tests/cmd/draid.c: We suppress one return value with
`(void)` since the code handles errors already. The other return value
is handled by switching to `fnvlist_lookup_uint8_array()`.
* tests/zfs-tests/cmd/file/file_fadvise.c: We add error handling.
* tests/zfs-tests/cmd/mmap_sync.c: We add error handling for munmap, but
ignore failures on remove() with (void) since it is expected to be
able to fail.
* tests/zfs-tests/cmd/mmapwrite.c: We add error handling.
As for unused return values, they were all in places where there was
error handling, so logic was added to handle the return values.

The current codebase does not support raw sending buffers with block
size > 128kB when large_blocks is not active. This can happen in the
codepath dsl_dataset_sync()->dmu_objset_sync()->zio_nowait() which
calls back dmu_objset_write_done()->dsl_dataset_block_born(). If
dsl_dataset_sync() completes its run before dsl_dataset_block_born() is
called, we will end up not activating some of the necessary flags, while
having blocks based on those flags written in the filesystem. A
subsequent send will then panic.
Fix this by directly deciding in dmu_objset_sync() whether these flags
need to be activated later by dsl_dataset_sync(). Instead of panicking
due to a NULL pointer dereference in dmu_dump_write() in case of a send,
print out an error message. Also during scrub verify there are no

This commit adds BLAKE3 checksums to OpenZFS, it has similar

Homepage of BLAKE3: https://github.com/BLAKE3-team/BLAKE3
Wikipedia: https://en.wikipedia.org/wiki/BLAKE_(hash_function)#BLAKE3
Short description of Wikipedia:
BLAKE3 is a cryptographic hash function based on Bao and BLAKE2,
created by Jack O'Connor, Jean-Philippe Aumasson, Samuel Neves, and
Zooko Wilcox-O'Hearn. It was announced on January 9, 2020, at Real
World Crypto. BLAKE3 is a single algorithm with many desirable
features (parallelism, XOF, KDF, PRF and MAC), in contrast to BLAKE
and BLAKE2, which are algorithm families with multiple variants.
BLAKE3 has a binary tree structure, so it supports a practically
unlimited degree of parallelism (both SIMD and multithreading) given
enough input. The official Rust and C implementations are
dual-licensed as public domain (CC0) and the Apache License.
Along with adding the BLAKE3 hash into the OpenZFS infrastructure a
new benchmarking file called chksum_bench was introduced. When read
it reports the speed of the available checksum functions.
On Linux: cat /proc/spl/kstat/zfs/chksum_bench
On FreeBSD: sysctl kstat.zfs.misc.chksum_bench

Structurally, the new code is mainly split into these parts:
- 1x cross platform generic c variant: blake3_generic.c
- 4x assembly for X86-64 (SSE2, SSE4.1, AVX2, AVX512)
- 2x assembly for ARMv8 (NEON converted from SSE2)
- 2x assembly for PPC64-LE (POWER8 converted from SSE2)
- one file for switching between the implementations
Note the PPC64 assembly requires the VSX instruction set and the
kfpu_begin() / kfpu_end() calls on PowerPC were updated accordingly.

Closes#10058Closes#12918
The EXTRA_DIST variable is ignored when used in the FALSE conditional
of a Makefile.am. This results in the `make dist` target omitting
these files from the generated tarball unless CONFIG_USER is defined.
This issue can be avoided by switching to use the dist_noinst_DATA
variable which is handled as expected by autoconf.
This change also adds support for --with-config=dist as an alias
for --with-config=srpm and updates the GitHub workflows to use it.

The short-path is now one access() call,
we always modprobe zfs (ZFS_MODULE_LOADING which doesn't use the libzfs
boolean parsing is gone),
and we use a simple inotify IN_CREATE loop with a timerfd timeout
rather than 10ms kernel-style polling
There's one substantial difference: ZFS_MODULE_TIMEOUT=-1
now means "never give up", rather than "wait 10 minutes"
