The pam ZTS tests were reporting a buffer overflow on F38, possibly
due to F38 now setting _FORTIFY_SOURCE=3 by default. gdb and
valgrind narrowed this down to a snprintf() buffer overflow in
zfs_key_config_modify_session_counter(). I'm not clear why this
particular snprintf() was being flagged as an overflow, but when
I replaced it with an asprintf(), the test passed reliably.

f6a0dac84 modified the zfs_iter_* functions to take a new "flags"
parameter, and introduced a variety of flags to ask the kernel to limit
the results in various ways, reducing the amount of work the caller
needed to do to filter out things they didn't need.
Unfortunately this change broke the ABI for existing clients (read:
older versions of the `zfs` program), and was reverted 399b98198.
dc95911d2 reintroduced the original patch, with the understanding that a
backwards-compatible fix would be made before the 2.2 release branch was
tagged. This commit is that fix.
This introduces zfs_iter_*_v2 functions that have the new flags
argument, and reverts the existing functions to not have the flags
parameter, as they were before. The old functions are now reimplemented
in terms of the new, with flags set to 0.

This had always worked in my testing, but a user on hardware reported
this to happen 100%, and I reproduced it once with cold VM host caches.
dracut-zfs-generator runs as a systemd generator, i.e. at Some
Relatively Early Time; if root= is a fixed dataset, it tries to
"solve [necessities] statically at generation time".
If by that point zfs-import.target hasn't popped (because the import is
taking a non-negligible amount of time for whatever reason), it'll see
no children for the root datase, and as such generate no mounts.
This has never had any right to work. No-one caught this earlier because
it's just that much more convenient to have root=zfs:AUTO, which orders
itself properly.
To fix this, always run zfs-nonroot-necessities.service;
this additionally simplifies the implementation by:
* making BOOTFS from zfs-env-bootfs.service be the real, canonical,
root dataset name, not just "whatever the first bootfs is",
and only set it if we're ZFS-booting
* zfs-{rollback,snapshot}-bootfs.service can use this instead of
re-implementing it
* having zfs-env-bootfs.service also set BOOTFSFLAGS
* this means the sysroot.mount drop-in can be fixed text
* zfs-nonroot-necessities.service can also be constant and always
enabled, because it's conditioned on BOOTFS being set
There is no longer any code generated at run-time
(the sysroot.mount drop-in is an unavoidable gratuitous cp).
The flow of BOOTFS{,FLAGS} from zfs-env-bootfs.service to sysroot.mount
is not noted explicitly in dracut.zfs(7), because (a) at some point it's
just visual noise and (b) it's already ordered via d-p-m.s from z-i.t.

If the fields to be listed and sorted by are constrained to those
populated by dsl_dataset_fast_stat(), then zfs list is much faster,
as it does not need to open each objset and reads its properties.
A previous optimization by Pawel Dawidek
(0cee24064a) took advantage
of this to make listing snapshot names sorted only by name much faster.
However, it was limited to `-o name -s name`, this work extends this
optimization to work with:
- name
- guid
- createtxg
- numclones
- inconsistent
- redacted
- origin
and could be further extended to any other properties supported by
dsl_dataset_fast_stat() or similar, that do not require extra locking
or reading from disk.
This was committed before (9a9e2e343dfa2af28bf7910de77ae73aa006de62),

Upon review, it was found that the model for malloc() was incorrect.
In addition, several general purpose memory allocation functions were
missing models:
* kmem_vasprintf()
* kmem_asprintf()
* kmem_strdup()
* kmem_strfree()
* spl_vmem_alloc()
* spl_vmem_zalloc()
* spl_vmem_free()
* calloc()
As an experiment to try to find more bugs, some less than general
purpose memory allocation functions were also given models:
* zfsvfs_create()
* zfsvfs_free()
* nvlist_alloc()
* nvlist_dup()
* nvlist_free()
* nvlist_pack()
* nvlist_unpack()
Finally, the models were improved using additional coverity primitives:
* __coverity_negative_sink__()
* __coverity_writeall0__()
* __coverity_mark_as_uninitialized_buffer__()
* __coverity_mark_as_afm_allocated__()
In addition, an attempt to inform coverity that certain modelled
functions read entire buffers was used by adding the following to
certain models:
int first = buf[0];
int last = buf[buflen-1];
It was inspired by the QEMU model file.
No additional false positives were found by this, but it is believed
that the more accurate model file will help to catch false positives in
the future.

Both Clang's Static Analyzer and Synopsys' Coverity would ignore
assertions. Following Clang's advice, we annotate our assertions:
https://clang-analyzer.llvm.org/annotations.html#custom_assertions
This makes both Clang's Static Analyzer and Coverity properly identify
assertions. This change reduced Clang's reported defects from 246 to
180. It also reduced the false positives reported by Coverityi by 10,
while enabling Coverity to find 9 more defects that previously were
false negatives.
A couple examples of this would be CID-1524417 and CID-1524423. After
submitting a build to coverity with the modified assertions, CID-1524417
disappeared while the report for CID-1524423 no longer claimed that the
assertion tripped.
Coincidentally, it turns out that it is possible to more accurately
annotate our headers than the Coverity modelling file permits in the
case of format strings. Since we can do that and this patch annotates
headers whenever `__coverity_panic__()` would have been used in the
model file, we drop all models that use `__coverity_panic__()` from the
model file.
Upon seeing the success in eliminating false positives involving
assertions, it occurred to me that we could also modify our headers to
eliminate coverity's false positives involving byte swaps. We now have
coverity specific byteswap macros, that do nothing, to disable
Coverity's false positives when we do byte swaps. This allowed us to
also drop the byteswap definitions from the model file.
Lastly, a model file update has been done beyond the mentioned
deletions:
* The definitions of `umem_alloc_aligned()`, `umem_alloc()` andi
`umem_zalloc()` were originally implemented in a way that was
intended to inform coverity that when KM_SLEEP has been passed these
functions, they do not return NULL. A small error in how this was
done was found, so we correct it.
* Definitions for umem_cache_alloc() and umem_cache_free() have been
added.
In practice, no false positives were avoided by making these changes,
but in the interest of correctness from future coverity builds, we make
them anyway.

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#12263
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.

No installation diff, dist lost
-zfs-2.1.99/cmd/fsck_zfs/fsck.zfs
which was distributed erroneously, since it's generated
Also clean gitrev on clean
Also add -e 'any possible bashisms' to default checkbashisms flags,
and fully parallelise it and shellcheck, and it works out-of-tree, too
Also align the Release in the dist META file correctly
