If `receive_writer_thread()` gets an error from `receive_process_record()`,
it should be saved in `rwa->err` so that we will stop processing records,
and the main thread will notice that the receive has failed.
When an error is first encountered, this happens correctly. However, if
there are more records to dequeue, the next time through the loop we
will reset `rwa->err` to zero, allowing us to try to process the
following record (2 after the failed record). Depending on what types
of records remain, we may incorrectly complete the receive
"successfully", but without actually having processed all the records.
The fix is to only set `rwa->err` if we got a *non-zero* error.
This bug was introduced by #10099 "Improve zfs receive performance by

When a resilver finishes, vdev_dtl_reassess is called to hopefully
excise DTL_MISSING (amongst other things). If there are errors during
the resilver, they are tracked in DTL_SCRUB, as spelled out in the
block comment in vdev.c. DTL_SCRUB is in-core only, so it can only
be used if the pool was online for the whole resilver. This state is
tracked with the spa_scrub_started flag, which only gets set when
the scan is initialized. Unfortunately, this flag gets cleared right
before vdev_dtl_reassess gets called, so if there are any errors
during the scan, DTL_MISSING will never get excised and the resilver
will just continually restart. This fix simply moves clearing that
flag until after the call to vdev_dtl_reasses.
In addition, if a pool is imported and already has scn_errors > 0,
this change will restart the resilver immediately instead of doing
the rest of the scan and then restarting it from the beginning. On
the other hand, if scn_errors == 0 at import, then no errors have
been encountered so far, so the spa_scrub_started flag can be safely
set.
A test has been added to verify that resilver does not restart when
relevant DTL's are available.

Functional changes:
We implement refcounts of log blocks and their aligned size on the
cache device along with two corresponding arcstats. The refcounts are
reflected in the header of the device and provide valuable information
as to whether log blocks are accounted for correctly. These are
dynamically adjusted as log blocks are committed/evicted. zdb also uses
this information in the device header and compares it to the
corresponding values as reported by dump_l2arc_log_blocks() which
emulates l2arc_rebuild(). If the refcounts saved in the device header
report higher values, zdb exits with an error. For this feature to work
correctly there should be no active writes on the device. This is also
employed in the tests of persistent L2ARC. We extend the structure of
the cache device header by adding the two new variables mirroring the
refcounts after the existing variables to preserve backward
compatibility in terms of persistent L2ARC.
1) a new arcstat "l2_log_blk_asize" and refcount "l2ad_lb_asize" which
reflect the total aligned size of log blocks on the device. This is
also reflected in the header of the cache device as "dh_lb_asize".
2) a new arcstat "l2arc_log_blk_count" and refcount "l2ad_lb_count"
which reflect the total number of L2ARC log blocks present on cache
devices. It is also reflected in the header of the cache device as
"dh_lb_count".
In l2arc_rebuild_vdev() if the amount of committed log entries in a log
block is 0 and the device header is valid we update the device header.
This will facilitate trimming of the whole device in this case when
TRIM for L2ARC is implemented.
Improve loop protection in l2arc_rebuild() by using the starting offset
of the payload of each log block instead of the starting offset of the
log block.
If the zio in l2arc_write_buffers() fails, restore the lbps array in the
header of the device to its previous state in l2arc_write_done().
If l2arc_rebuild() ends the rebuild process without restoring any L2ARC
log blocks in ARC and without any other error, this means that the lbps
array in the header is pointing to non-existent or invalid log blocks.
Reset the device header in this case.
In l2arc_rebuild() change the zfs_dbgmsg messages to
spa_history_log_internal() making them user visible with zpool history
command.
Non-functional changes:
Make the first test in persistent L2ARC use `zdb -lll` to increase
coverage in `zdb.c`.
Rename psize with asize when referring to log blocks, since
L2ARC_SET_PSIZE stores the vdev aligned size for log blocks. Also
rename dh_log_blk_entries to dh_log_entries to make it clear that
it is a mirror of l2ad_log_entries. Added comments for both changes.
Fix inaccurate comments for example in l2arc_log_blk_restore().
Add asserts at the end in l2arc_evict() and l2arc_write_buffers().

Modern bootloaders leverage data stored in the root filesystem to
enable some of their powerful features. GRUB specifically has a grubenv
file which can store large amounts of configuration data that can be
read and written at boot time and during normal operation. This allows
sysadmins to configure useful features like automated failover after
failed boot attempts. Unfortunately, due to the Copy-on-Write nature
of ZFS, the standard behavior of these tools cannot handle writing to
ZFS files safely at boot time. We need an alternative way to store
data that allows the bootloader to make changes to the data.
This work is very similar to work that was done on Illumos to enable
similar functionality in the FreeBSD bootloader. This patch is different
in that the data being stored is a raw grubenv file; this file can store
arbitrary variables and values, and the scripting provided by grub is
powerful enough that special structures are not required to implement
advanced behavior.
We repurpose the second padding area in each label to store the grubenv
file, protected by an embedded checksum. We add two ioctls to get and
set this data, and libzfs_core and libzfs functions to access them more
easily. There are no direct command line interfaces to these functions;
these will be added directly to the bootloader utilities.

Sync up with the following changes from FreeBSD:
ZFS: add emulation of atomic_swap_64 and atomic_load_64
Some 32-bit platforms do not provide 64-bit atomic operations that ZFS
requires, either in userland or at all. We emulate those operations
for those platforms using a mutex. That is not entirely correct and
it's very efficient. Besides, the loads are plain loads, so torn
values are possible.
Nevertheless, the emulation seems to work for some definition of work.
This change adds atomic_swap_64, which is already used in ZFS code,
and atomic_load_64 that can be used to prevent torn reads.

FreeBSD-commit: freebsd/freebsd@3458e5d1e6
cleanup of illumos compatibility atomics
atomic_cas_32 is implemented using atomic_fcmpset_32 on all platforms.
Ditto for atomic_cas_64 and atomic_fcmpset_64 on platforms that have
it. The only exception is sparc64 that provides MD atomic_cas_32 and
atomic_cas_64.
This is slightly inefficient as fcmpset reports whether the operation
updated the target and that information is not needed for cas.
Nevertheless, there is less code to maintain and to add for new
platforms. Also, the operations are done inline now as opposed to
function calls before.
atomic_add_64_nv is implemented using atomic_fetchadd_64 on platforms
that provide it.
casptr, cas32, atomic_or_8, atomic_or_8_nv are completely removed as
they have no users.
atomic_mtx that is used to emulate 64-bit atomics on platforms that
lack them is defined only on those platforms.
As a result, platform specific opensolaris_atomic.S files have lost
most of their code. The only exception is i386 where the
compat+contrib code provides 64-bit atomics for userland use. That
code assumes availability of cmpxchg8b instruction. FreeBSD does not
have that assumption for i386 userland and does not provide 64-bit
atomics. Hopefully, this can and will be fixed.

FreeBSD-commit: freebsd/freebsd@e9642c209b
emulate illumos membar_producer with atomic_thread_fence_rel
membar_producer is supposed to be a store-store barrier.
Also, in the code that FreeBSD has ported from illumos membar_producer
is used only with regular stores to regular memory (with respect to
caching).
We do not have an MI primitive for the store-store barrier, so
atomic_thread_fence_rel is the closest we have as it provides
(load | store) -> store barrier.
Previously, membar_producer was an empty function call on all 32-bit
arm-s, 32-bit powerpc, riscv and all mips variants. I think that it
was inadequate.
On other platforms, such as amd64, arm64, i386, powerpc64, sparc64,
membar_producer was implemented using stronger primitives than required
for a store-store barrier with respect to regular memory access.
For example, it used sfence on amd64 and lock-ed nop in i386 (despite
TSO).
On powerpc64 we now use recommended lwsync instead of eieio.
On sparc64 FreeBSD uses TSO mode.
On arm64/aarch64 we now use dmb sy instead of dmb ish. Not sure if
this is an improvement, actually.
After this change we can drop opensolaris_atomic.S for aarch64, amd64,
powerpc64 and sparc64 as all required atomic operations have either
direct or light-weight mapping to FreeBSD native atomic operations.

fcmpset can have two kinds of semantics, weak and strong.
For practical purposes, strong semantics means that if fcmpset fails
then the reported current value is always different from the expected
value. Weak semantics means that the reported current value may be the
same as the expected value even though fcmpset failed. That's a so
called "sporadic" failure.
I originally implemented atomic_cas expecting strong semantics, but
many platforms actually have weak one.

[PowerPC] [MIPS] Implement 32-bit kernel emulation of atomic64 operations
This is a lock-based emulation of 64-bit atomics for kernel use, split off
from an earlier patch by jhibbits.
This is needed to unblock future improvements that reduce the need for
locking on 64-bit platforms by using atomic updates.
The implementation allows for future integration with userland atomic64,
but as that implies going through sysarch for every use, the current
status quo of userland doing its own locking may be for the best.

would probably use libcurl, etc). It would be helpful if libzfs can
be extended to support additional schemes in a simple manner.
A table of (scheme, handler_function) pairs is added to libzfs_crypto.c,
and the existing functions in libzfs_crypto.c so that when the key
format is ZFS_KEYFORMAT_URI, the scheme from the URI string is
extracted, and a matching handler it located in the aforementioned
table (returning an error if no matching handler is found). The handler
function is then invoked to retrieve the key material (in the format
specified by the keyformat property) and the key is loaded or the
handler can return an error to abort the key loading process.

zlib_inflateEnd was accidentally a wrapper for inflateInit instead of
inflateEnd, and hilarity ensues.
Fix the typo so we free memory instead of allocating more.

This patch corrects a bug introduced in 61152d1069. When
resuming a raw base receive, the dmu_recv code always sets
drc->drc_fromsnapobj to the object ID of the previous
snapshot. For incrementals, this is correct, but for base
sends, this should be left at 0. The presence of this ID
eventually allows a check to run which determines whether
or not the incoming stream and the previous snapshot have
matching IVset guids. This check fails becuase it is not
meant to run when there is no previous snapshot. When it
does fail, the user receives an error stating that the
incoming stream has the problem outlined in errata 4.
This patch corrects this issue by simply ensuring
drc->drc_fromsnapobj is left as 0 for base receives.

Fix uninitialized variable in `zstream redup` command. The compiler
may determine the 'stream_offset' variable can be uninitialized
because not all rdt_lookup() exit paths set it. This should never
happen in practice as documented by the assert, but initialize it
regardless to resolve the warning.

This aids in debugging, so that we can use the same infrastructure to
walk zfs's list_t in the kernel module and in the userland libraries
(e.g. when debugging ztest).

Closes#10236
Deduplicated send streams (i.e. `zfs send -D` and `zfs receive` of such
streams) are deprecated. Deduplicated send streams can be received by
first converting them to non-deduplicated with the `zstream redup`
command.
This commit removes the code for sending and receiving deduplicated send
streams. `zfs send -D` will now print a warning, ignore the `-D` flag,
and generate a regular (non-deduplicated) send stream. `zfs receive` of
a deduplicated send stream will print an error message and fail.
The resulting code simplification (especially in the kernel's support
for receiving dedup streams) should help enable future performance
enhancements.
Several new tests are added which leverage `zstream redup`.
