In #13709, as in #11294 before it, it turns out that 63a26454 still had
the same failure mode as when it was first landed as d1d47691, and
fails to unlock certain datasets that formerly worked.
Rather than reverting it again, let's add handling to just throw out
the accounting metadata that failed to unlock when that happens, as
well as a test with a pre-broken pool image to ensure that we never get
bitten by this again.

The original ARC paper called for an initial 50/50 MRU/MFU split
and this is accounted in various places where arc_p = arc_c >> 1,
with further adjustment based on ghost lists size/hit. However, in
current code both arc_adapt() and arc_get_data_impl() aggressively
grow arc_p until arc_c is reached, causing unneeded pressure on
MFU and greatly reducing its scan-resistance until ghost list
adjustments kick in.
This patch restores the original behavior of initially having arc_p
as 1/2 of total ARC, without preventing MRU to use up to 100% total
ARC when MFU is empty.

Some of our customers have been occasionally hitting zfs import failures
in Linux because udevd doesn't create the by-id symbolic links in time
for zpool import to use them. The main issue is that the
systemd-udev-settle.service that zfs-import-cache.service and other
services depend on is racy. There is also an openzfs issue filed (see
https://github.com/openzfs/zfs/issues/10891) outlining the problem and
potential solutions.
With the proper solutions being significant in terms of complexity and
the priority of the issue being low for the time being, this patch
exposes `zfs_vdev_open_timeout_ms` as a tunable so people that are
experiencing this issue often can increase it as a workaround.

CodeQL reported that when the VERIFY3U condition is false, we do not
pass enough arguments to `spl_panic()`. This is because the format
string from `snprintf()` was concatenated into the format string for
`spl_panic()`, which causes us to have an unexpected format specifier.
A CodeQL developer suggested fixing the macro to have a `%s` format
string that takes a stringified RIGHT argument, which would fix this.
However, upon inspection, the VERIFY3U check was never necessary in the
first place, so we remove it in favor of just calling `snprintf()`.
Lastly, it is interesting that every other static analyzer run on the
codebase did not catch this, including some that made an effort to catch
such things. Presumably, all of them relied on header annotations, which
we have not yet done on `spl_panic()`. CodeQL apparently is able to
track the flow of arguments on their way to annotated functions, which
llowed it to catch this when others did not. A future patch that I have
in development should annotate `spl_panic()`, so the others will catch
this too.

Out of the 12 defects in lua that coverity reports, 5 of them involve
`lua_typename()` and out of the dozens of defects in ZFS that lua
reports, 3 of them involve `lua_typename()` due to the ZCP code. Given
all of the uses of `lua_typename()` in the ZCP code, I was surprised
that there were not more. It appears that only 2 were reported because
only 3 called `lua_type()`, which does a defective sanity check that
allows invalid types to be passed.
lua/lua@d4fb848be7 addressed this in
upstream lua 5.3. Unfortunately, we did not get that fix since we use
lua 5.2 and we do not have assertions enabled in lua, so the upstream
solution would not do anything.
While we could adopt the upstream solution and enable assertions, a
simpler solution is to fix the issue by making `lua_typename()` return
`internal_type_error` whenever it is called with an invalid type. This
avoids the array overflow and if we ever see it appear somewhere, we
will know there is a problem with the lua interpreter.

Currently, only Blake3 x86 Asm code has signs of being ENDBR-aware.
At least, under certain conditions it includes some header file and
uses some custom macro from there.
Linux has its own NOENDBR since several releases ago. It's defined
in the same <asm/linkage.h>, so currently <sys/asm_linkage.h>
already is provided with it.
Let's unify those two into one %ENDBR macro. At first, check if it's
present already. If so -- use Linux kernel version. Otherwise, try
to go that second way and use %_CET_ENDBR from <cet.h> if available.
If no, fall back to just empty definition.
This fixes a couple more 'relocations to !ENDBR' across the module.
And now that we always have the latest/actual ENDBR definition, use
it at the entrance of the few corresponding functions that objtool
still complains about. This matches the way how it's used in the
upstream x86 core Asm code.

where those object files were excluded from objtool check (but they
can still be visible under IBT and LTO), those are just constants,
not code.
In that case, they must be placed in .rodata, so they won't be
marked as "allocatable, executable" (ax) in EFL headers and this
effectively prevents objtool from trying to decode this data. That
reveals a whole bunch of other issues in ICP Asm code, as previously
objtool was bailing out after that warning message.

Commit 43569ee374 ("Fix objtool: missing int3 after ret warning")
addressed replacing all `ret`s in x86 asm code to a macro in the
Linux kernel in order to enable SLS. That was done by copying the
upstream macro definitions and fixed objtool complaints.
Since then, several more mitigations were introduced, including
Rethunk. It requires to have a jump to one of the thunks in order
to work, so the RET macro was changed again. And, as ZFS code
didn't use the mainline defition, but copied it, this is currently
missing.
Objtool reminds about it time to time (Clang 16, CONFIG_RETHUNK=y):
fs/zfs/lua/zlua.o: warning: objtool: setjmp+0x25: 'naked' return
found in RETHUNK build
fs/zfs/lua/zlua.o: warning: objtool: longjmp+0x27: 'naked' return
found in RETHUNK build
Do it the following way:
* if we're building under Linux, unconditionally include
<linux/linkage.h> in the related files. It is available in x86
sources since even pre-2.6 times, so doesn't need any conftests;
* then, if RET macro is available, it will be used directly, so that
we will always have the version actual to the kernel we build;
* if there's no such macro, we define it as a simple `ret`, as it
was on pre-SLS times.
This ensures we always have the up-to-date definition with no need
to update it manually, and at the same time is safe for the whole
variety of kernels ZFS module supports.
Then, there's a couple more "naked" rets left in the code, they're
just defined as:
.byte 0xf3,0xc3
In fact, this is just:
rep ret
`rep ret` instead of just `ret` seems to mitigate performance issues
on some old AMD processors and most likely makes no sense as of
today.
Anyways, address those rets, so that they will be protected with
Rethunk and SLS. Include <sys/asm_linkage.h> here which now always
has RET definition and replace those constructs with just RET.
This wipes the last couple of places with unpatched rets objtool's
been complaining about.

Commit 68ddc06b61 introduced support
for receiving unencrypted datasets as children of encrypted ones but
unfortunately got the logic upside down. This resulted in failing to
deny receives of incremental sends into encrypted datasets without
their keys loaded. If receiving a filesystem, the receive was done
into a newly created unencrypted child dataset of the target. In
case of volumes the receive made the target volume undeletable since
a dataset was created below it, which we obviously can't handle.
Incremental streams with embedded blocks are affected as well.
We fix the broken logic to properly deny receives in such cases.
