b9aa32ff39 zed: Reduce log noise for large JBODs
For large JBODs the log message "zfs_iter_vdev: no match" can
account for the bulk of the log messages (over 70%).  Since this
message is purely informational and not that useful we remove it.

8c81c0b05d zed: Fix zed ASSERT on slot power cycle
We would see zed assert on one of our systems if we powered off a
slot.  Further examination showed zfs_retire_recv() was reporting
a GUID of 0, which in turn would return a NULL nvlist.  Add
in a check for a zero GUID.

Probe vdevs before marking removed
Before allowing the ZED to mark a vdev as REMOVED due to a
hotplug event confirm that it is non-responsive with probe.
Any device which can be successfully probed should be left
ONLINE to prevent a healthy pool from being incorrectly
SUSPENDED.  This may occur for at least the following two
scenarios.

1) Drive expansion (zpool online -e) in VMware environments.
   If, during the partition resize operation, a partition is
   removed and re-created then udev will send a removed event.

2) Re-scanning the namespaces of an NVMe device (nvme ns-rescan)
   may result in a udev remove and add event being delivered.

Finally, update the ZED to only kick in a spare when the
removal was successful.

d1807f168e nvpair: Constify string functions
After addressing coverity complaints involving `nvpair_name()`, the
compiler started complaining about dropping const. This lead to a rabbit
hole where not only `nvpair_name()` needed to be constified, but also
`nvpair_value_string()`, `fnvpair_value_string()` and a few other static
functions, plus variable pointers throughout the code. The result became
a fairly big change, so it has been split out into its own patch.

Configure zed's diagnosis engine with vdev properties
Introduce four new vdev properties:
    checksum_n
    checksum_t
    io_n
    io_t

These properties can be used for configuring the thresholds of zed's
diagnosis engine and are interpeted as <N> events in T <seconds>.

When this property is set to a non-default value on a top-level vdev,
those thresholds will also apply to its leaf vdevs. This behavior can be
overridden by explicitly setting the property on the leaf vdev.

Note that, these properties do not persist across vdev replacement. For
this reason, it is advisable to set the property on the top-level vdev
instead of the leaf vdev.

The default values for zed's diagnosis engine (10 events, 600 seconds)
remains unchanged.

zed: unclean disk attachment faults the vdev
If the attached disk already contains a vdev GUID, it
means the disk is not clean. In such a scenario, the

97143b9d31 Introduce kmem_scnprintf()
`snprintf()` is meant to protect against buffer overflows, but operating
on the buffer using its return value, possibly by calling it again, can
cause a buffer overflow, because it will return how many characters it
would have written if it had enough space even when it did not. In a
number of places, we repeatedly call snprintf() by successively
incrementing a buffer offset and decrementing a buffer length, by its
return value. This is a potentially unsafe usage of `snprintf()`
whenever the buffer length is reached. CodeQL complained about this.

To fix this, we introduce `kmem_scnprintf()`, which will return 0 when
the buffer is zero or the number of written characters, minus 1 to
exclude the NULL character, when the buffer was too small. In all other
cases, it behaves like snprintf(). The name is inspired by the Linux and
XNU kernels' `scnprintf()`. The implementation was written before I
thought to look at `scnprintf()` and had a good name for it, but it
turned out to have identical semantics to the Linux kernel version.
That lead to the name, `kmem_scnprintf()`.

CodeQL only catches this issue in loops, so repeated use of snprintf()
outside of a loop was not caught. As a result, a thorough audit of the
codebase was done to examine all instances of `snprintf()` usage for
potential problems and a few were caught. Fixes for them are included in
this patch.

Unfortunately, ZED is one of the places where `snprintf()` is
potentially used incorrectly. Since using `kmem_scnprintf()` in it would
require changing how it is linked, we modify its usage to make it safe,
no matter what buffer length is used. In addition, there was a bug in
the use of the return value where the NULL format character was not
being written by pwrite(). That has been fixed.

Handle possible null pointers from malloc/strdup/strndup()
GCC 12.1.1_p20220625's static analyzer caught these.

Of the two in the btree test, one had previously been caught by Coverity
and Smatch, but GCC flagged it as a false positive. Upon examining how
other test cases handle this, the solution was changed from
`ASSERT3P(node, !=, NULL);` to using `perror()` to be consistent with
the fixes to the other fixes done to the ZTS code.

That approach was also used in ZED since I did not see a better way of
handling this there. Also, upon inspection, additional unchecked
pointers from malloc()/calloc()/strdup() were found in ZED, so those
were handled too.

In other parts of the code, the existing methods to avoid issues from
memory allocators returning NULL were used, such as using
`umem_alloc(size, UMEM_NOFAIL)` or returning `ENOMEM`.

Reduce false positives from Static Analyzers
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.

Fix unchecked return values and unused return values
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.

zed: Fix config_sync autoexpand flood
Users were seeing floods of `config_sync` events when autoexpand was
enabled.  This happened because all "disk status change" udev events
invoke the autoexpand codepath, which calls zpool_relabel_disk(),
which in turn cause another "disk status change" event to happen,
in a feedback loop.  Note that "disk status change" happens every time
a user calls close() on a block device.

This commit breaks the feedback loop by only allowing an autoexpand
to happen if the disk actually changed size.

Prevent zevent list from consuming all of kernel memory
There are a couple changes included here. The first is to introduce 
a cap on the size the ZED will grow the zevent list to. One million 
entries is more than enough for most use cases, and if you are 
overflowing that value, the problem needs to be addressed another 
way. The value is also tunable, for those who want the limit to be 
higher or lower. 
 
The other change is to add a kernel module parameter that allows 
snapshot creation/deletion to be exempted from the history logging; 
for most workloads, having these things logged is valuable, but for 
some workloads it produces large quantities of log spam and isn't 
especially helpful.

zed: Take no action on scrub/resilver checksum errors
When scrubbing/resilvering a pool it can be counter productive to
cancel the scan and kick of a replace operation to a hot spare
when encountering checksum errors.  In this case, the best course
of action is to allow the scrub/resilver to complete as quickly
as possible and to keep the vdevs fully online if possible.

Realistically, this is less of an issue for a RAIDZ since a
traditional resilver must be used and checksums will be verified.
However, this is not the case for a mirror or dRAID pool which is
sequentially resilvered and checksum verification is deferred
until after the replace operation completes.

Regardless, we apply this policy to all pool types since it's
a good idea for all vdevs.  Degrading additional vdevs has the
potential to make a bad situation worse.  Note the checksum
errors will still be reported as both an event and by
`zpool status`.  This change only prevents the ZED from
proactively taking any action.

It doesn't matter, 0600 are Weird Permissions, and it's even weirder to
spec them for no reason ‒ it's perfectly fine if it's the usual 0:0 644,
or literally anything else, so long as unprivileged users can't edit it
(which (a) 644 accomplishes and (b) is at the administrator's
 discretion, it's not unheard of to have adm users and having it
 be 664 in that case is just as good; it's not our place to say)

zed: Misc multipath autoreplace fixes
We recently had a case where our operators replaced a bad
multipathed disk, only to see it fail to autoreplace.  The
zed logs showed that the multipath replacement disk did not pass
the 'is_dm' test in zfs_process_add() even though it should have.
is_dm is set if there exists a sysfs entry for to the
underlying /dev/sd* paths for the multipath disk.  It's
possible this path didn't exist due to a race condition where
the sysfs paths weren't created at the time the udev event came
in to zed, but this was never verified.

This patch updates the check to look for udev properties that
indicate if the new autoreplace disk is an empty multipath disk,
rather than looking for the underlying sysfs entries. It also
adds in additional logging, and fixes a bug where zed allowed
you to use an already zfs-formatted disk from another pool
as a multipath auto-replacement disk.

Furthermore, while testing this patch, I also ran across a case
where a force-faulted disk did not have a ZPOOL_CONFIG_PHYS_PATH
entry in its config.  This prevented it from being autoreplaced.
I added additional logic to derive the PHYS_PATH from the PATH if
the PATH was a /dev/disk/by-vdev/ path.  For example, if PATH
was /dev/disk/by-vdev/L28, then PHYS_PATH would be L28.  This is
safe since by-vdev paths represent physical locations and do not
change between boots.

Change enforced shell type from `dash` to `sh` and excluded
`SC2039` and `SC3043` by default. `local` keyword is accepted by all
POSIX shells from practical point of view. There is no need anymore
to enforce dash so `local` is accepted.

zed-functions.sh: escape newline to produce valid json
This was discovered when using Discords Slack compatible webhook.

Slack webhooks works without the escape, however Discord rightly refuses
the POST as it contains invalid JSON.

https://discord.com/developers/docs/resources/webhook#execute-slackcompatible-webhook

Valid (while escaping the newline:
```
+ msg_json='{"text": "*ZFS scrub_finish error for test on quartz*\nZFS has detected a data error:\n\n   eid: 124\n class: scrub_finish\n  host: quartz\n  time: \n error: \n objid: :\n  pool: test\n"}'
```

Invalid (no escape):
```
+ msg_json='{"text": "*ZFS scrub_finish error for test on quartz*
ZFS has detected a data error:\n\n   eid: 124\n class: scrub_finish\n  host: quartz\n  time: \n error: \n objid: :\n  pool: test\n"}'
```
The new line gets rendered and not sent inside the JSON as intended.

```
++ curl -X POST https://discord.com/api/webhooks/{webhook.id}/{webhook.token}/slack --header 'Content-Type: application/json' --data-binary '{"text": "*ZFS scrub_finish error for test on quartz*
ZFS has detected a data error:\n\n   eid: 124\n class: scrub_finish\n  host: quartz\n  time: \n error: \n objid: :\n  pool: test\n"}'
+ msg_out='{"message": "Cannot send an empty message", "code": 50006}'
```

Test method:
`root@quartz:/etc/zfs/zed.d# export ZED_ZEDLET_DIR=/etc/zfs/zed.d; export ZEVENT_EID=124; export ZEVENT_SUBCLASS=scrub_finish; export ZEVENT_POOL=test; export ZED_NOTIFY_DATA=1; bash -x ./data-notify.sh`
