loli10K e05c965d5b Fix for ARC sysctls ignored at runtime
This change leverage module_param_call() to run arc_tuning_update()
immediately after the ARC tunable has been updated as suggested in
cffa837 code review.
A simple test case is added to the ZFS Test Suite to prevent future
regressions in functionality.

This is a backport of #9489 provided from:

Brian Behlendorf 9791683901 cppcheck: (warning) Possible null pointer dereference: nvh
Move the 'nvh = (void *)buf' assignment after the 'buf == NULL'
check to resolve the warning.  Interestingly, cppcheck 1.88
correctly determines that the existing code is safe, while
cppcheck 1.86 reports the warning.

On systems that utilize TTY for password entry, if the kernel
option "quiet" is set, the system would appear to freeze on a
blank screen, when in fact it is waiting for password entry
from the user.

Since TTY is the fallback method, this has no effect on systemd
or plymouth password prompting.

By temporarily setting "printk" to "7", running the command,
then resuming with the original "printk" state, the user can
see the password prompt.

Richard Laager 0f256176d9 initramfs: setup keymapping and video for prompts
From Steve Langasek <steve.langasek@canonical.com>:
> The poorly-named 'FRAMEBUFFER' option in initramfs-tools controls
> whether the console_setup and plymouth scripts are included and used
> in the initramfs. These are required for any initramfs which will be
> prompting for user input: console_setup because without it the user's

> not guaranteed to have working video output in the initramfs without
> it (e.g. some nvidia+UEFI configurations with the default GRUB

> The zfs initramfs script may need to prompt the user for passphrases
> for encrypted zfs datasets, and we don't know definitively whether
> this is the case or not at the time the initramfs is constructed (and
> it's difficult to dynamically populate initramfs config variables
> anyway), therefore the zfs-initramfs package should just set
> FRAMEBUFFER=yes in a conf snippet the same way that the
> cryptsetup-initramfs package does
> (/usr/share/initramfs-tools/conf-hooks.d/cryptsetup).

Tom Caputi 7ad0ae91d5 Allow empty ds_props_obj to be destroyed
Currently, 'zfs list' and 'zfs get' commands can be slow when
working with snapshots that have a ds_props_obj. This is
because the code that discovers all of the properties for these
snapshots needs to read this object for each snapshot, which
almost always ends up causing an extra random synchronous read
for each snapshot. This performance penalty exists even if the
properties on that snapshot have been unset because the object
is normally only freed when the snapshot is freed, even though
it is only created when it is needed.

This patch allows the user to regain 'zfs list' performance on
these snapshots by destroying the ds_props_obj when it no longer
has any entries left. In practice on a production machine, this
optimization seems to make 'zfs list' about 55% faster.

Matthew Ahrens 856d185dc2 Fix use-after-free of vd_path in spa_vdev_remove()
After spa_vdev_remove_aux() is called, the config nvlist is no longer
valid, as it's been replaced by the new one (with the specified device
removed).  Therefore any pointers into the nvlist are no longer valid.
So we can't save the result of
`fnvlist_lookup_string(nv, ZPOOL_CONFIG_PATH)` (in vd_path) across the
call to spa_vdev_remove_aux().

Instead, use spa_strdup() to save a copy of the string before calling
spa_vdev_remove_aux.

In case L2ARC read failed, l2arc_read_done() creates _different_ ZIO
to read data from the original storage device.  Unfortunately pointer
to the failed ZIO remains in hdr->b_l1hdr.b_acb->acb_zio_head, and if
some other read try to bump the ZIO priority, it will crash.

The problem is reproducible by corrupting L2ARC content and reading
some data with prefetch if l2arc_noprefetch tunable is changed to 0.
With the default setting the issue is probably not reproducible now.

If zp->z_unlinked is set, we're working with a znode that has been
marked for deletion. If that's the case, we can skip the "goto again"
loop and return ENOENT, as the znode should not be discovered.

loli10K 880a37aa35 Prevent NULL pointer dereference in blkg_tryget() on EL8 kernels
blkg_tryget() as shipped in EL8 kernels does not seem to handle NULL
@blkg as input; this is different from its mainline counterpart where
NULL is accepted.  To prevent dereferencing a NULL pointer when dealing
with block devices which do not set a root_blkg on the request queue
perform the NULL check in vdev_bio_associate_blkg().

Brian Behlendorf 2c7549fb6f Fix `zpool create -o <property>` error message
When `zpool create -o <property>` is run without root permissions
and the pool property requested is not specifically enumerated in
zpool_valid_proplist().  Then an incorrect error message referring
to an invalid property is printed rather than the expected permission
denied error.

Specifying a pool property at create time should be handled the same
way as filesystem properties in zfs_valid_proplist().  There should
not be default zfs_error_aux() set for properties which are not
listed.

Alexander Motin edaec84225 Improve logging of 128KB writes
Before my ZIL space optimization few years ago 128KB writes were logged
as two 64KB+ records in two 128KB log blocks.  After that change it
became ~127KB+/1KB+ in two 128KB log blocks to free space in the second
block for another record.  Unfortunately in case of 128KB only writes,
when space in the second block remained unused, that change increased
write latency by unbalancing checksum computation and write times
between parallel threads.  It also didn't help with SLOG space
efficiency in that case.

This change introduces new 68KB log block size, used for both writes
below 67KB and 128KB-sharp writes.  Writes of 68-127KB are still using
one 128KB block to not increase processing overhead.  Writes above
131KB are still using full 128KB blocks, since possible saving there
is small.  Mixed loads will likely also fall back to previous 128KB,
since code uses maximum of the last 16 requested block sizes.

Tom Caputi 7e1b772edd Fix 'zfs change-key' with unencrypted child
Currently, when you call 'zfs change-key' on an encrypted dataset
that has an unencrypted child, the code will trigger a VERIFY.
This VERIFY is leftover from before we allowed unencrypted
datasets to exist underneath encrypted ones. This patch fixes the
issue by simply replacing the VERIFY with an early return when
recursing through datasets.

Tom Caputi 635603a1c2 Fix incremental recursive encrypted receive
Currently, incremental recursive encrypted receives fail to work
for any snapshot after the first. The reason for this is because
the check in zfs_setup_cmdline_props() did not properly realize
that when the user attempts to use '-x encryption' in this
situation, they are not really overriding the existing encryption
property and instead are attempting to prevent it from changing.
This resulted in an error message stating: "encryption property
'encryption' cannot be set or excluded for raw or incremental
streams".

This problem is fixed by updating the logic to expect this use
case.
