The ICP requires destructors to for each crypto module that is added.
These do not necessarily exist in Illumos because they assume that
these modules can never be unloaded from the kernel. Some of this
cleanup code was missed when #4760 was merged, resulting in leaks.
This patch simply fixes that.

This is as much an upstream compatibility as it's a bit of a performance

As to performance, if this taskq is dynamic, it can cause excessive

Call mount and umount via /usr/bin/env instead of /bin/sh in

This change fixes a shell code injection flaw. The call to /bin/sh
passed the mountpoint unescaped, only surrounded by single quotes. A
mountpoint containing one or more single quotes would cause the command
to fail or potentially execute arbitrary shell code.
This change also provides compatibility with grsecurity patches.
Grsecurity only allows call_usermodehelper() to use helper binaries in

Using a benchmark which creates 2 million files in one TXG, I observe
that the thread running spa_sync() is on CPU almost the entire time we
are syncing, and therefore can be a performance bottleneck. About 50% of
the time in spa_sync() is in dmu_objset_do_userquota_updates().
The problem is that dmu_objset_do_userquota_updates() calls
zap_increment_int(DMU_USERUSED_OBJECT) once for every file that was
modified (or created). In this benchmark, all the files are owned by the
same user/group, so all 2 million calls to zap_increment_int() are
modifying the same entry in the zap. The same issue exists for the
DMU_GROUPUSED_OBJECT.
We should keep an in-memory map from user to space delta while we are
syncing, and when we finish, iterate over the in-memory map and modify
the ZAP once per entry. This reduces the number of calls to
zap_increment_int() from "number of objects modified" to "number of
owners/groups of modified files".
This reduced the time spent in spa_sync() in the file create benchmark
by ~33%, from 11 seconds to 7 seconds.

The behavior of the Dracut module was very wrong before.
The correct behavior: initramfs should not run `zfs-mount` to completion
if the two generator files exist. If, however, one of them is missing,
it indicates one of three cases:
* The kernel command line did not specify a root ZFS file system, and
another Dracut module is already handling root mount (via systemd).
`mount-zfs` can run, but it will do nothing.
* There is no systemd to run `sysroot.mount` to begin with.
`mount-zfs` must run.
* The root parameter is zfs:AUTO, which cannot be run in sysroot.mount.
`mount-zfs` must run.
In any of these three cases, it is safe to run `zfs-mount` to completion.
`zfs-mount` must also delete itself if it determines it should not run,
or else Dracut will do the insane thing of running it over and over again.
Literally, the definition of insanity, doing the same thing that did not
work before, expecting different results. Doing that may have had a great
result before, when we had a race between devices appearing and pools
being mounted, and `mount-zfs` was tasked with the full responsibility
of importing the needed pool, but nowadays it is wrong behavior and
should be suppressed.
I deduced that self-deletion was the correct thing to do by looking at
other Dracut code, because (as we all are very fully aware of) Dracut
is entirely, ahem, "implementation-defined".

Combine incrementally computed fletcher4 checksums. Checksums are combined
a posteriori, allowing for parallel computation on chunks to be implemented if
required. The algorithm is general, and does not add changes in each SIMD
implementation.
New test in ztest verifies incremental fletcher computations.
Checksum combining matrix for two buffers `a` and `b`, where `Ca` and `Cb` are
respective fletcher4 checksums, `Cab` is combined checksum, `s` is size of buffer
`b` (divided by sizeof(uint32_t)) is:
Cab[A] = Cb[A] + Ca[A]
Cab[B] = Cb[B] + Ca[B] + s * Ca[A]
Cab[C] = Cb[C] + Ca[C] + s * Ca[B] + s(s+1)/2 * Ca[A]
Cab[D] = Cb[D] + Ca[D] + s * Ca[C] + s(s+1)/2 * Ca[B] + s(s+1)(s+2)/6 * Ca[A]
NOTE: this calculation overflows for larger buffers. Thus, internally, the calculation
is performed on 8MiB chunks.

As part of its tests, filetest_001_pos.ksh wipes the entire vdev to

using the entire device size that is passed into zfs-tests.sh
(which defaults to 2GB). This speeds up the buildbot tests, and also
makes it possible for someone to use real disks (say, 1TB) without the
test taking an insanely long amount of time.

zio_checksum_to_feature() expects a zio_checksum enum not a raw property
intval, so the new checksums weren't being detected when the
ZIO_CHECKSUM_VERIFY flag got in the way.
Given a pool without feature@sha512,
zfs create -o dedup=sha512 naughty/fivetwelve_noverify_ds
would fail as expected since the raw intval would indeed be equal to
SPA_FEATURE_SHA512.
However,
zfs create -o dedup=sha512,verify naughty/fivetwelve_verify_ds
would incorrectly succeed because ZIO_CHECKSUM_VERIFY would be in the
way, the raw intval would not be a member of the enum, and
zio_checksum_to_feature() would return SPA_FEATURE_NONE, with the result
that spa_feature_is_enabled() would never be called.
This was first detected with edonr, since in that case verify is
required.
This commit clears the ZIO_CHECKSUM_VERIFY flag before calling
zio_checksum_to_feature() using the ZIO_CHECKSUM_MASK and verifies in
zio_checksum_to_feature() that ZIO_CHECKSUM_MASK has been applied by the
caller to attempt to prevent the same bug from occurring again in the
future.

This re-use the framework established for SSE2, SSSE3 and
AVX2. However, GCC is using FP registers on Aarch64, so
unlike SSE/AVX2 we can't rely on the registers being left alone
between ASM statements. So instead, the NEON code uses
C variables and GCC extended ASM syntax. Note that since
the kernel explicitly disable vector registers, they
have to be locally re-enabled explicitly.
As we use the variable's number to define the symbolic
name, and GCC won't allow duplicate symbolic names,
numbers have to be unique. Even when the code is not
going to be used (e.g. the case for 4 registers when
using the macro with only 2). Only the actually used
variables should be declared, otherwise the build
will fails in debug mode.
This requires the replacement of the XOR(X,X) syntax
by a new ZERO(X) macro, which does the same thing but
without repeating the argument. And perhaps someday
there will be a machine where there is a more efficient
way to zero a register than XOR with itself. This affects
scalar, SSE2, SSSE3 and AVX2 as they need the new macro.
It's possible to write faster implementations (different
scheduling, different unrolling, interleaving NEON and
scalar, ...) for various cores, but this one has the
advantage of fitting in the current state of the code,
and thus is likely easier to review/check/merge.
The only difference between aarch64-neon and aarch64-neonx2
is that aarch64-neonx2 unroll some functions some more.
