Cedric Maunoury db9b29895e send_iterate_snap : doall send without fromsnap
The behavior of a NULL fromsnap was inadvertently changed for a doall
send when the send/recv logic in libzfs was updated.  Restore the
previous behavior by correcting send_iterate_snap() to include all
the snapshots in the nvlist for this case.

fbynite 4d4dd76f0f vdev_ops: don't try to call vdev_op_hold or vdev_op_rele when NULL
This prevents a panic after a SLOG add/removal on the root pool followed
by a zpool scrub.

When a SLOG is removed, a hole takes its place - the vdev_ops for a hole
is vdev_hole_ops, which defines the handler functions of vdev_op_hold
and vdev_op_rele as NULL.

This bug has been reported in illumos and FreeBSD, a different trigger
in the FreeBSD report though.

Mark Johnston f17c843eff FreeBSD: disable the use of hardware crypto offload drivers for now
First, the crypto request completion handler contains a bug in that it
fails to reset fs_done correctly after the request is completed.  This
is only a problem for asynchronous drivers.  Second, some hardware
drivers have input constraints which ZFS does not satisfy.  For
instance, ccp(4) apparently requires the AAD length for AES-GCM to be a
multiple of the cipher block size, and with qat(4) the AES-GCM AAD
length may not be longer than 240 bytes.  FreeBSD's generic crypto
framework doesn't have a mechanism to automatically fall back to a
software implementation if a hardware driver cannot process a request,
and ZFS does not tolerate such errors.

The plan is to implement such a fallback mechanism, but with FreeBSD
13.0 approaching we should simply disable the use hardware drivers for
now.

Andriy Gapon f6440fa094 Fix report_mount_progress never calling set_progress_header
That happens because of an off-by-one mistake.
share_mount_one_cb() calls report_mount_progress(current=sm_done) after
having incremented sm_done by one.  Then report_mount_progress()
increments the parameter again.  It appears that that logic became
obsolete after commit a10d50f999, parallel zfs mount.

On FreeBSD I observe that zfs mount -a -v prints, for example,
    (null): (201/248)
That happens because set_progress_header() is never called.

With this change the output becomes correct:
    Mounting ZFS filesystems: (209/248)

Antonio Russo 8829ba19b7 Set file mode during zfs_write
3d40b65 refactored zfs_vnops.c, which shared much code verbatim between
Linux and BSD.  After a successful write, the suid/sgid bits are reset,
and the mode to be written is stored in newmode.  On Linux, this was
propagated to both the in-memory inode and znode, which is then updated
with sa_update.

3d40b65 accidentally removed the initialization of newmode, which
happened to occur on the same line as the inode update (which has been
moved out of the function).

The uninitialized newmode can be saved to disk, leading to a crash on
stat() of that file, in addition to a merely incorrect file mode.

наб 642d86af0d zfs-import-{cache,scan}: change condition to FileNotEmpty
When all pools are exported ZFS will generate an empty cache file.
This will cause the import service to fail, which is sub-optimal, 
since this means that dracut fails, and it necessary to run 
`zpool import -a` to boot, delete the file, and regenerate+reinstall 
the initrd.

This resolves the issue by treating an zero-length cache files the
same as a missing cache file.  This aligns the behavior with that
of the `zpool` command itself.

There is a race condition in zfs_zrele_async when we are checking if 
we would be the one to evict an inode. This can lead to a txg sync 
deadlock.

Instead of calling into iput directly, we attempt to perform the atomic 
decrement ourselves, unless that would set the i_count value to zero. 
In that case, we dispatch a call to iput to run later, to prevent a 
deadlock from occurring.

Antonio Russo 81f981cd82 ZTS: avoid piping to special devices
As described in #11445, the kernel interface kernel_{read,write} no
longer act on special devices.  In the ZTS, zfs send and receive are
tested by piping to these devices, leading to spurious failures (for
positive tests) and may mask errors (for negative tests).

Until a more permanent mechanism to address this deficiency is
developed, clean up the output from the ZTS by avoiding directly piping
to or from /dev/null and /dev/zero.

For /dev/zero input, simply use a pipe: `cat </dev/zero |` .

However, for /dev/null output, the shell semantics for pipe failures
means that zfs send error codes will be masked by the successful
`| cat >/dev/null` command execution.  In that case, use a temporary
file under $TEST_BASE_DIR for output in favor.

If the system is very low on memory (specifically,
`arc_free_memory() < arc_sys_free/2`, i.e. less than 1/16th of RAM
free), `arc_evict_state_impl()` will defer wakups.  In this case, the
arc_evict_waiter_t's remain on the list, even though `arc_evict_count`
has been incremented past their `aew_count`.

The problem is that `arc_wait_for_eviction()` assumes that if there are
waiters on the list, the count they are waiting for has not yet been
reached.  However, the deferred wakeups may violate this, causing
`ASSERT(last->aew_count > arc_evict_count)` to fail.

This commit resolves the issue by having new waiters use the greater of
`arc_evict_count` and the last `aew_count`.

Matthew Ahrens a296875da0 nvlist leaked in zpool_find_config()
In `zpool_find_config()`, the `pools` nvlist is leaked.  Part of it (a
sub-nvlist) is returned in `*configp`, but the callers also leak that.

Additionally, in `zdb.c:main()`, the `searchdirs` is leaked.

The leaks were detected by ASAN (`configure --enable-asan`).

This commit resolves the leaks.

The same issue is present in openzfs, and also the same issue about
ds_hold_flags_t, which currently defines exactly one valid value.

Brian Behlendorf fcd9966ed9 Linux 5.11 compat: blk_{un}register_region()
As of 5.11 the blk_register_region() and blk_unregister_region()
functions have been retired. This isn't a problem since add_disk()
has implicitly allocated minor numbers for a very long time.

Brian Behlendorf a2621753b2 Linux 5.11 compat: revalidate_disk_size()
Both revalidate_disk_size() and revalidate_disk() have been removed.
Functionally this isn't a problem because we only relied on these
functions to call zvol_revalidate_disk() for us and to perform any
additional handling which might be needed for that kernel version.
When neither are available we know there's no additional handling
needed and we can directly call zvol_revalidate_disk().

Brian Behlendorf e888f28988 Linux 5.11 compat: bdev_whole()
The bd_contains member was removed from the block_device structure.
Callers needing to determine if a vdev is a whole block device should
use the new bdev_whole() wrapper.  For older kernels we provide our
own bdev_whole() wrapper which relies on bd_contains for compatibility.
