This comes from the observation that a huge number of commit author
fields look quite strange (to my eyes), but quite often the
Signed-off-by: trailer has the correct name. For these I have updated
the name where it was obvious how to do so, however, I have not created
a mapping for the commit email to the Signed-off-by email, as whatever I
choose for email will become the prime candidate for inclusion in the
AUTHORS file, and care needs to be taken when acting without explicit
consent.
There's a small handful of commits that look like they were done on
local machines, or CI hosts, or similar, where the git authorship config
wasn't set up properly. Its obvious what this should look like, so I've
just done them.
The remainder is mapping Github noreply emails to either an
obviously-correct Signed-off-by trailer, or to a an author from another
commit. This was mostly done by hand, so there may be errors, but I
think its close. I do not understand where these come from - I know that
they're what commits made via Github web look like when there's no real
address set on the account, but I find it hard to believe that so many
of these came through the web, especially given the complexity of most
of the changes. I suspect there's some kind of merge helper tool in play
here. Regardless, the history is set now, and this tries to get it back
on track.
Obviously, all of this helps the history look tidy, but this also feeds
into the AUTHORS update script. See next commit.

Previously, if a cachefile is passed to zpool import, the cached config
is mostly offered as-is to ZFS_IOC_POOL_TRYIMPORT->spa_tryimport(), and
the results are taken as the canonical pool config and handed back to
ZFS_IOC_POOL_IMPORT.
In the course of its operation, spa_load() will inspect the pool and
build a new config from what it finds on disk. However, it then
regenerates a new config ready to import, and so rightly sets the hostid
and hostname for the local host in the config it returns.
Because of this, the "require force" checks always decide the pool is
exported and last touched by the local host, even if this is not true,
which is possible in a HA environment when MMP is not enabled. The pool
may be imported on another head, but the import checks still pass here,
so the pool ends up imported on both.
(This doesn't happen when a cachefile isn't used, because the pool
config is discovered in userspace in zpool_find_import(), and that does
find the on-disk hostid and hostname correctly).
Since the systemd zfs-import-cache.service unit uses cachefile imports,
this can lead to a system returning after a crash with a "valid"
cachefile on disk and automatically, quietly, importing a pool that has
already been taken up by a secondary head.
This commit causes the on-disk hostid and hostname to be included in the
ZPOOL_CONFIG_LOAD_INFO item in the returned config, and then changes the
"force" checks for zpool import to use them if present.
This method should give no change in behaviour for old userspace on new
kernels (they won't know to look for the new config items) and for new
userspace on old kernels (the won't find the new config items).

Before this change ZFS created threads for 50% of CPUs for each top-
level vdev. Plus it created the same number of threads for embedded
log groups (that have only one metaslab and don't need any preload).
As result, on system with 80 CPUs and pool of 60 vdevs this resulted
in 4800 metaslab preload threads, that is absolutely insane.
This patch changes the preload threads to 50% of CPUs in one taskq
per pool, so on the mentioned system it will be only 40 threads.
Among other things this fixes zdb on the mentioned system and pool

To reduce memory usage ZFS crypto allocated bigger by 56 bytes ARC
headers only when specific block was encrypted on disk. It was a
nice optimization, except in some cases the code reallocated them
on fly, that invalidated header pointers from the buffers. Since
the buffers use different locking, it created number of races, that
were originally covered (at least partially) by b_evict_lock, used
also to protection evictions. But it has gone as part of #14340.
As result, as was found in #15293, arc_hdr_realloc_crypt() ended
up unprotected and causing use-after-free.
Instead of introducing some even more elaborate locking, this patch
just drops the difference between normal and protected headers. It
cost us additional 56 bytes per header, but with couple patches
saving 24 bytes, the net growth is only 32 bytes with total header
size of 232 bytes on FreeBSD, that IMHO is acceptable price for
simplicity. Additional locking would also end up consuming space,
time or both.

In most cases we do not care about exact number of buffers linked
to the header, we just need to know if it is zero, non-zero or one.
That can easily be checked just looking on b_buf pointer or in some
cases derefencing it.
b_ebufcnt is read only once, and in that case we already traverse
the list as part of arc_buf_remove(), so second traverse should not
be expensive.
This reduces L1 ARC header size by 8 bytes and full crypto header by
16 bytes, down to 176 and 232 bytes on FreeBSD respectively.

The problem that was occurring is basically that a device was removed
by ztest and replaced with another device. It was then reguided. The
import then failed because there were two possible imports with the
same name; one with the new guid, and one with the old. This can
happen because the label writes from the device removal/replacement
can be subject to ztest's error injection.
The other ways to fix this would be to change the error injection to
not trigger on removals (which may not be technically feasible), or
to change the import code to not report configurations that are so
short on devices (which would potentially have unpleasant end-user
effects when trying to recover from data losses/device configuration

direct-access calls. The code that operated on an address of ip->i_ctime
to call ZFS_TIME_DECODE() now will take a local copy using
zpl_inode_get_ctime(), and then pass the address of the local copy when
performing the ZFS_TIME_DECODE() call, in all cases, rather than

We've observed this test failing intermittently. When it does, the

The only way this could have happened is if the open txg moved between
the dd and clonefile calls. That's possible because although we set
zfs_txg_timeout to be large, that only affects the wait time in the sync
thread at the start of a new txg; it doesn't change anything if its

So here we just force the txgs to move immediately before, which should

When failmode=continue is set and the pool suspends, both 'zpool status'
and the 'zfs/pool/state' kstat ignore it and report the normal vdev tree
state. There's no clear indicator that the pool is suspended. This is
unlike suspend in failmode=wait, or suspend due to MMP check failure,
which both report "SUSPENDED" explicitly.
This commit changes it so SUSPENDED is reported for failmode=continue
the same as for other modes.
Rationale:
The historical behaviour of failmode=continue is roughly, "press on as
though all is well". To this end, the fact that the pool had suspended
was not shown, to maintain the façade that all is well.
Its unclear why hiding this information was considered appropriate. One
possibility is that it was expected that a true pool fault would always
be reported as DEGRADED or FAULTED, and that the pool could not suspend
without these happening.
That is not necessarily true, as vdev health and suspend state are only
loosely connected, such that a pool in (apparent) good health can be
suspended for good reasons, and of course a degraded pool does not lead
to suspension. Even if that expectation were true, there's still a
difference in urgency - a degraded pool may not need to be attended to
for hours, while a suspended pool is most often unusable until an
operator intervenes.
An operator that has set failmode=continue has presumably done so
because their workload is one that can continue to operate in a useful
way when the pool suspends. In this case the operator still needs a
clear indicator that there is a problem that needs attending to.

Chiefly:
- Remove unnecessary parentheses around variable names.
- Remove spaces between the type and variable in casts.
- Make the panic message for VERIFY0() reflect how the macro is used.
- Use %p to format pointers, except in Linux kernel code.

Closes#15225
For sharesmb and sharenfs properties, the status of setting the
property is tied with whether we succeed to share the dataset or
not. In case sharing the dataset is not successful, this is
treated as overall failure of setting the property. In this case,
if we check the property after the failure, it is set to on.
This commit updates this behavior and the status of setting the
share properties is not returned as failure, when we fail to
share the dataset.
For sharenfs property, if access list is provided, the syntax
errors in access list/host adresses are not validated until after
setting the property during postfix phase while trying to
share the dataset. This is not correct, since the property has
already been set when we reach there.
Syntax errors in access list/host addresses are validated while
validating the property list, before setting the property and
failure is returned to user in this case when there are errors
in access list.
