ZIL: Fix another use-after-free.
lwb->lwb_issued_txg can not be accessed after lwb_state is set to
LWB_STATE_FLUSH_DONE and zl_lock is dropped, since the lwb may be
freed by zil_sync(). We must save the txg number before that.
This is similar to the 55b1842f92, but as I see the bug is not new.
It existed for quite a while, just was not triggered due to smaller
race window.

Use big transactions for small recordsize writes.
When ZFS appends files in chunks bigger than recordsize, it borrows
buffer from ARC and fills it before opening transaction. This
supposed to help in case of page faults to not hold transaction open
indefinitely. The problem appears when recordsize is set lower than
default 128KB. Since each block is committed in separate transaction,
per-transaction overhead becomes significant, and what is even worse,
active use of of per-dataset and per-pool locks to protect space use
accounting for each transaction badly hurts the code SMP scalability.
The same transaction size limitation applies in case of file rewrite,
but without even excuse of buffer borrowing.
To address the issue, disable the borrowing mechanism if recordsize
is smaller than default and the write request is 4x bigger than it.
In such case writes up to 32MB are executed in single transaction,
that dramatically reduces overhead and lock contention. Since the
borrowing mechanism is not used for file rewrites, and it was never
used by zvols, which seem to work fine, I don't think this change
should create significant problems, partially because in addition to
the borrowing mechanism there are also used pre-faults.
My tests with 4/8 threads writing several files same time on datasets
with 32KB recordsize in 1MB requests show reduction of CPU usage by
the user threads by 25-35%. I would measure it in GB/s, but at that
block size we are now limited by the lock contention of single write
issue taskqueue, which is a separate problem we are going to work on.

Another set of vdev queue optimizations.
Switch FIFO queues (SYNC/TRIM) and active queue of vdev queue from
time-sorted AVL-trees to simple lists. AVL-trees are too expensive
for such a simple task. To change I/O priority without searching
through the trees, add io_queue_state field to struct zio.
To not check number of queued I/Os for each priority add vq_cqueued
bitmap to struct vdev_queue. Update it when adding/removing I/Os.
Make vq_cactive a separate array instead of struct vdev_queue_class
member. Together those allow to avoid lots of cache misses when
looking for work in vdev_queue_class_to_issue().
Introduce deadline of ~0.5s for LBA-sorted queues. Before this I
saw some I/Os waiting in a queue for up to 8 seconds and possibly
more due to starvation. With this change I no longer see it. I
had to slightly more complicate the comparison function, but since
it uses all the same cache lines the difference is minimal. For a
sequential I/Os the new code in vdev_queue_io_to_issue() actually
often uses more simple avl_first(), falling back to avl_find() and
avl_nearest() only when needed.
Arrange members in struct zio to access only one cache line when
searching through vdev queues. While there, remove io_alloc_node,
reusing the io_queue_node instead. Those two are never used same
time.
Remove zfs_vdev_aggregate_trim parameter. It was disabled for 4
years since implemented, while still wasted time maintaining the
offset-sorted tree of TRIM requests. Just remove the tree.
Remove locking from txg_all_lists_empty(). It is racy by design,
while 2 pair of locks/unlocks take noticeable time under the vdev
queue lock.
With these changes in my tests with volblocksize=4KB I measure vdev
queue lock spin time reduction by 50% on read and 75% on write.

Add a delay to tearing down threads.
It's been observed that in certain workloads (zvol-related being a
big one), ZFS will end up spending a large amount of time spinning
up taskqs only to tear them down again almost immediately, then
spin them up again...
I noticed this when I looked at what my mostly-idle system was doing
and wondered how on earth taskq creation/destroy was a bunch of time...
So I added a configurable delay to avoid it tearing down tasks the
first time it notices them idle, and the total number of threads at
steady state went up, but the amount of time being burned just
tearing down/turning up new ones almost vanished.

Remove ARC/ZIO physdone callbacks.
Those callbacks were introduced many years ago as part of a bigger
patch to smoothen the write throttling within a txg. They allow to
account completion of individual physical writes within a logical
one, improving cases when some of physical writes complete much
sooner than others, gradually opening the write throttle.
Few years after that ZFS got allocation throttling, working on a
level of logical writes and limiting number of writes queued to
vdevs at any point, and so limiting latency distribution between
the physical writes and especially writes of multiple copies.
The addition of scheduling deadline I proposed in #14925 should
further reduce the latency distribution. Grown memory sizes over
the past 10 years should also reduce importance of the smoothing.
While the use of physdone callback may still in theory provide
some smoother throttling, there are cases where we simply can not
afford it. Since dirty data accounting is protected by pool-wide
lock, in case of 6-wide RAIDZ, for example, it requires us to take
it 8 times per logical block write, creating huge lock contention.
My tests of this patch show radical reduction of the lock spinning
time on workloads when smaller blocks are written to RAIDZ pools,
when each of the disks receives 8-16KB chunks, but the total rate
reaching 100K+ blocks per second. Same time attempts to measure
any write time fluctuations didn't show anything noticeable.
While there, remove also io_child_count/io_parent_count counters.
They are used only for couple assertions that can be avoided.

1) vdev_alloc() assigns the ashift of the pool to L2ARC device, but
upon export it is not stored anywhere
2) at the first import, vdev_open() sees an vdev_ashift() of 0 and
assigns the logical_ashift, which is 9
3) reading the contents of L2ARC, including the header fails
4) L2ARC buffers are not restored in ARC.

Fix the L2ARC write size calculating logic (2)
While commit bcd5321 adjusts the write size based on the size of the log
block, this happens after comparing the unadjusted write size to the
evicted (target) size.
In this case l2ad_hand will exceed l2ad_evict and violate an assertion
at the end of l2arc_write_buffers().
Fix this by adding the max log block size to the allocated size of the
buffer to be committed before comparing the result to the target
size.
Also reset the l2arc_trim_ahead ZFS module variable when the adjusted
write size exceeds the size of the L2ARC device.

Finally drop long disabled vdev cache.
It was a vdev level read cache, designed to aggregate many small
reads by speculatively issuing bigger reads instead and caching
the result. But since it has almost no idea about what is going
on with exception of ZIO_FLAG_DONT_CACHE flag set by higher layers,
it was found to make more harm than good, for which reason it was
disabled for the past 12 years. These days we have much better
instruments to enlarge the I/Os, such as speculative and prescient
prefetches, I/O scheduler, I/O aggregation etc.
Besides just the dead code removal this removes one extra mutex
lock/unlock per write inside vdev_cache_write(), not otherwise
disabled and trying to do some work.

PAM: support password changes even when not mounted
There's usually no requirement that a user be logged in for changing
their password, so let's not be surprising here.
We need to use the fetch_lazy mechanism for the old password to avoid
a double prompt for it, so that mechanism is now generalized a bit.

btree: Implement faster binary search algorithm
This implements a binary search algorithm for B-Trees that reduces
branching to the absolute minimum necessary for a binary search
algorithm. It also enables the compiler to inline the comparator to
ensure that the only slowdown when doing binary search is from waiting
for memory accesses. Additionally, it instructs the compiler to unroll
the loop, which gives an additional 40% improve with Clang and 8%
improvement with GCC.
Consumers must opt into using the faster algorithm. At present, only
B-Trees used inside kernel code have been modified to use the faster
algorithm.
Micro-benchmarks suggest that this can improve binary search performance
by up to 3.5 times when compiling with Clang 16 and up to 1.9 times when
compiling with GCC 12.2.

Fix concurrent resilvers initiated at same time
For draid vdevs it was possible to initiate both the
sequential and healing resilver at same time.
This fixes the following two scenarios.
1) There's a window where a sequential rebuild can
be started via ZED even if a healing resilver has been
scheduled.
- This is fixed by adding additional check in
spa_vdev_attach() for any scheduled resilver and return
appropriate error code when a resilver is already in
progress.
2) It was possible for zpool clear to start a healing
resilver when it wasn't needed at all. This occurs because
during a vdev_open() the device is presumed to be healthy not
until the device is validated by vdev_validate() and it's set
unavailable. However, by this point an async resilver will
have already been requested if the DTL isn't empty.
- This is fixed by cancelling the SPA_ASYNC_RESILVER
request immediately at the end of vdev_reopen() when a resilver
is unneeded.
Finally, added a testcase in ZTS for verification.

Probe vdevs before marking removed
Before allowing the ZED to mark a vdev as REMOVED due to a
hotplug event confirm that it is non-responsive with probe.
Any device which can be successfully probed should be left
ONLINE to prevent a healthy pool from being incorrectly
SUSPENDED. This may occur for at least the following two
scenarios.
1) Drive expansion (zpool online -e) in VMware environments.
If, during the partition resize operation, a partition is
removed and re-created then udev will send a removed event.
2) Re-scanning the namespaces of an NVMe device (nvme ns-rescan)
may result in a udev remove and add event being delivered.
Finally, update the ZED to only kick in a spare when the
removal was successful.

adding a new flag, creating new libzfs interfaces, a new ioctl, and the
actual iteration and read-issuing logic. Error scrubbing is executed in

test-runner: pass kmemleak and kmsg to Cmd.run
test-runner.py orchestrates all of the ZTS executions. The `Cmd` object
manages these process, and its `run` method specifically invokes these
possibly long-running processes, possibly retrying in the event of a
timeout. Since its inception, memory leak detection using the kmemleak
infrastructure [1], and kernel logging [2] have been added to this run
mechanism.
However, the callback to cull a process beyond its timeout threshold,
`kill_cmd`, has evaded modernization by both of these changes. As a
result, this function fails to properly invoke `run`, leading to an
untrapped exception and unreported test failure.
This patch extends `kill_cmd` to receive these kernel devices through
the `options` parameter, and regularizes all the `.run` calls from
`Cmd`, and its subclasses, to accept that parameter.

Fix undefined behavior in spa_sync_props()
8eae2d214cfa53862833eeeda9a5c1e9d5ded47d caused Coverity to begin
complaining about "Improper use of negative value" in two places in
spa_sync_props() because Coverity correctly inferred from `prop ==
ZPOOL_PROP_INVAL` that prop could be -1 while both zpool_prop_to_name()
and zpool_prop_get_type() use it an array index, which is undefined
behavior.
Assuming that the system does not panic from an attempt to read invalid
memory, the case statement for ZPOOL_PROP_INVAL will ensure that only
user properties will reach this code when prop is ZPOOL_PROP_INVAL, such
that execution will continue safely. However, if we are unlucky enough
to read invalid memory, then the system will panic.
This issue predates the patch that caused coverity to begin complaining.
Thankfully, our userland tools do not pass nonsense to us, so this bug
should not be triggered unless a future userland tool attempts to set a
property that we do not understand.

Deny block cloning is dbuf size doesn't match BP size.
I don't know an easy way to shrink down dbuf size, so just deny block cloning
into dbufs that don't match our BP's size.
This fixes the following situation:
1. Create a small file, eg. 1kB of random bytes. Its dbuf will be 1kB.
2. Create a larger file, eg. 2kB of random bytes. Its dbuf will be 2kB.
3. Truncate the large file to 0. Its dbuf will remain 2kB.
4. Clone the small file into the large file. Small file's BP lsize is
1kB, but the large file's dbuf is 2kB.

pam: Fix "buffer overflow" in pam ZTS tests on F38
The pam ZTS tests were reporting a buffer overflow on F38, possibly

valgrind narrowed this down to a snprintf() buffer overflow in
zfs_key_config_modify_session_counter(). I'm not clear why this
particular snprintf() was being flagged as an overflow, but when
I replaced it with an asprintf(), the test passed reliably.

Enable the head_errlog feature to remove errors
In case check_filesystem() does not error out and does not report
an error, remove that error block from error lists and logs
without requiring a scrub. This can happen when the original file and
all snapshots/clones referencing it have been removed.
Otherwise zpool status will still report that "Permanent errors have
been detected..." without actually reporting any of them.
To implement this change the functions introduced in corrective
receive were modified to take into account the head_errlog feature.

corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

errors: Permanent errors have been detected in the following files:

After this change:
=============================
pool: test
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are
unaffected.
action: Determine if the device needs to be replaced, and clear the
errors
using 'zpool clear' or replace the device with 'zpool replace'.

Verify block pointers before writing them out
If a block pointer is corrupted (but the block containing it checksums
correctly, e.g. due to a bug that overwrites random memory), we can
often detect it before the block is read, with the `zfs_blkptr_verify()`
function, which is used in `arc_read()`, `zio_free()`, etc.
However, such corruption is not typically recoverable. To recover from
it we would need to detect the memory error before the block pointer is
written to disk.
This PR verifies BP's that are contained in indirect blocks and dnodes
before they are written to disk, in `dbuf_write_ready()`. This way,
we'll get a panic before the on-disk data is corrupted. This will help
us to diagnose what's causing the corruption, as well as being much
easier to recover from.
To minimize performance impact, only checks that can be done without
holding the spa_config_lock are performed.
Additionally, when corruption is detected, the raw words of the block
pointer are logged. (Note that `dprintf_bp()` is a no-op by default,
but if enabled it is not safe to use with invalid block pointers.)

Fix TOCTOU race in zpool_do_labelclear()
Coverity reported a TOCTOU race in `zpool_do_labelclear()`. This is not
believed to be a real security issue, but fixing it reduces the number
of syscalls we do and will prevent other static analyzers from
complaining about this.
The code is expected to be equivalent. However, under rare
circumstances, such as ELOOP, ENAMETOOLONG, ENOMEM, ENOTDIR and
EOVERFLOW, we will display the error message that we currently display
for the `open()` syscall rather than the one that we currently display
for the `stat()` syscall. This is considered to be an improvement.

ZIL: Fix another use-after-free.
lwb->lwb_issued_txg can not be accessed after lwb_state is set to
LWB_STATE_FLUSH_DONE and zl_lock is dropped, since the lwb may be
freed by zil_sync(). We must save the txg number before that.
This is similar to the 55b1842f92, but as I see the bug is not new.
It existed for quite a while, just was not triggered due to smaller
race window.

Use big transactions for small recordsize writes.
When ZFS appends files in chunks bigger than recordsize, it borrows
buffer from ARC and fills it before opening transaction. This
supposed to help in case of page faults to not hold transaction open
indefinitely. The problem appears when recordsize is set lower than
default 128KB. Since each block is committed in separate transaction,
per-transaction overhead becomes significant, and what is even worse,
active use of of per-dataset and per-pool locks to protect space use
accounting for each transaction badly hurts the code SMP scalability.
The same transaction size limitation applies in case of file rewrite,
but without even excuse of buffer borrowing.
To address the issue, disable the borrowing mechanism if recordsize
is smaller than default and the write request is 4x bigger than it.
In such case writes up to 32MB are executed in single transaction,
that dramatically reduces overhead and lock contention. Since the
borrowing mechanism is not used for file rewrites, and it was never
used by zvols, which seem to work fine, I don't think this change
should create significant problems, partially because in addition to
the borrowing mechanism there are also used pre-faults.
My tests with 4/8 threads writing several files same time on datasets
with 32KB recordsize in 1MB requests show reduction of CPU usage by
the user threads by 25-35%. I would measure it in GB/s, but at that
block size we are now limited by the lock contention of single write
issue taskqueue, which is a separate problem we are going to work on.

Another set of vdev queue optimizations.
Switch FIFO queues (SYNC/TRIM) and active queue of vdev queue from
time-sorted AVL-trees to simple lists. AVL-trees are too expensive
for such a simple task. To change I/O priority without searching
through the trees, add io_queue_state field to struct zio.
To not check number of queued I/Os for each priority add vq_cqueued
bitmap to struct vdev_queue. Update it when adding/removing I/Os.
Make vq_cactive a separate array instead of struct vdev_queue_class
member. Together those allow to avoid lots of cache misses when
looking for work in vdev_queue_class_to_issue().
Introduce deadline of ~0.5s for LBA-sorted queues. Before this I
saw some I/Os waiting in a queue for up to 8 seconds and possibly
more due to starvation. With this change I no longer see it. I
had to slightly more complicate the comparison function, but since
it uses all the same cache lines the difference is minimal. For a
sequential I/Os the new code in vdev_queue_io_to_issue() actually
often uses more simple avl_first(), falling back to avl_find() and
avl_nearest() only when needed.
Arrange members in struct zio to access only one cache line when
searching through vdev queues. While there, remove io_alloc_node,
reusing the io_queue_node instead. Those two are never used same
time.
Remove zfs_vdev_aggregate_trim parameter. It was disabled for 4
years since implemented, while still wasted time maintaining the
offset-sorted tree of TRIM requests. Just remove the tree.
Remove locking from txg_all_lists_empty(). It is racy by design,
while 2 pair of locks/unlocks take noticeable time under the vdev
queue lock.
With these changes in my tests with volblocksize=4KB I measure vdev
queue lock spin time reduction by 50% on read and 75% on write.

Add a delay to tearing down threads.
It's been observed that in certain workloads (zvol-related being a
big one), ZFS will end up spending a large amount of time spinning
up taskqs only to tear them down again almost immediately, then
spin them up again...
I noticed this when I looked at what my mostly-idle system was doing
and wondered how on earth taskq creation/destroy was a bunch of time...
So I added a configurable delay to avoid it tearing down tasks the
first time it notices them idle, and the total number of threads at
steady state went up, but the amount of time being burned just
tearing down/turning up new ones almost vanished.

Remove ARC/ZIO physdone callbacks.
Those callbacks were introduced many years ago as part of a bigger
patch to smoothen the write throttling within a txg. They allow to
account completion of individual physical writes within a logical
one, improving cases when some of physical writes complete much
sooner than others, gradually opening the write throttle.
Few years after that ZFS got allocation throttling, working on a
level of logical writes and limiting number of writes queued to
vdevs at any point, and so limiting latency distribution between
the physical writes and especially writes of multiple copies.
The addition of scheduling deadline I proposed in #14925 should
further reduce the latency distribution. Grown memory sizes over
the past 10 years should also reduce importance of the smoothing.
While the use of physdone callback may still in theory provide
some smoother throttling, there are cases where we simply can not
afford it. Since dirty data accounting is protected by pool-wide
lock, in case of 6-wide RAIDZ, for example, it requires us to take
it 8 times per logical block write, creating huge lock contention.
My tests of this patch show radical reduction of the lock spinning
time on workloads when smaller blocks are written to RAIDZ pools,
when each of the disks receives 8-16KB chunks, but the total rate
reaching 100K+ blocks per second. Same time attempts to measure
any write time fluctuations didn't show anything noticeable.
While there, remove also io_child_count/io_parent_count counters.
They are used only for couple assertions that can be avoided.

2) at the first import, vdev_open() sees an vdev_ashift() of 0 and
assigns the logical_ashift, which is 9

Fix the L2ARC write size calculating logic (2)
While commit bcd5321 adjusts the write size based on the size of the log
block, this happens after comparing the unadjusted write size to the
evicted (target) size.
In this case l2ad_hand will exceed l2ad_evict and violate an assertion
at the end of l2arc_write_buffers().
Fix this by adding the max log block size to the allocated size of the
buffer to be committed before comparing the result to the target
size.
Also reset the l2arc_trim_ahead ZFS module variable when the adjusted
write size exceeds the size of the L2ARC device.

Finally drop long disabled vdev cache.
It was a vdev level read cache, designed to aggregate many small
reads by speculatively issuing bigger reads instead and caching
the result. But since it has almost no idea about what is going
on with exception of ZIO_FLAG_DONT_CACHE flag set by higher layers,
it was found to make more harm than good, for which reason it was
disabled for the past 12 years. These days we have much better
instruments to enlarge the I/Os, such as speculative and prescient
prefetches, I/O scheduler, I/O aggregation etc.
Besides just the dead code removal this removes one extra mutex
lock/unlock per write inside vdev_cache_write(), not otherwise
disabled and trying to do some work.

PAM: support password changes even when not mounted
There's usually no requirement that a user be logged in for changing
their password, so let's not be surprising here.
We need to use the fetch_lazy mechanism for the old password to avoid
a double prompt for it, so that mechanism is now generalized a bit.

btree: Implement faster binary search algorithm
This implements a binary search algorithm for B-Trees that reduces
branching to the absolute minimum necessary for a binary search
algorithm. It also enables the compiler to inline the comparator to
ensure that the only slowdown when doing binary search is from waiting
for memory accesses. Additionally, it instructs the compiler to unroll
the loop, which gives an additional 40% improve with Clang and 8%
improvement with GCC.
Consumers must opt into using the faster algorithm. At present, only
B-Trees used inside kernel code have been modified to use the faster
algorithm.
Micro-benchmarks suggest that this can improve binary search performance
by up to 3.5 times when compiling with Clang 16 and up to 1.9 times when
compiling with GCC 12.2.

Fix concurrent resilvers initiated at same time
For draid vdevs it was possible to initiate both the
sequential and healing resilver at same time.
This fixes the following two scenarios.
1) There's a window where a sequential rebuild can
be started via ZED even if a healing resilver has been
scheduled.
- This is fixed by adding additional check in
spa_vdev_attach() for any scheduled resilver and return
appropriate error code when a resilver is already in
progress.
2) It was possible for zpool clear to start a healing
resilver when it wasn't needed at all. This occurs because
during a vdev_open() the device is presumed to be healthy not
until the device is validated by vdev_validate() and it's set
unavailable. However, by this point an async resilver will
have already been requested if the DTL isn't empty.
- This is fixed by cancelling the SPA_ASYNC_RESILVER
request immediately at the end of vdev_reopen() when a resilver
is unneeded.
Finally, added a testcase in ZTS for verification.

Probe vdevs before marking removed
Before allowing the ZED to mark a vdev as REMOVED due to a
hotplug event confirm that it is non-responsive with probe.
Any device which can be successfully probed should be left
ONLINE to prevent a healthy pool from being incorrectly
SUSPENDED. This may occur for at least the following two
scenarios.
1) Drive expansion (zpool online -e) in VMware environments.
If, during the partition resize operation, a partition is
removed and re-created then udev will send a removed event.
2) Re-scanning the namespaces of an NVMe device (nvme ns-rescan)
may result in a udev remove and add event being delivered.
Finally, update the ZED to only kick in a spare when the
removal was successful.

adding a new flag, creating new libzfs interfaces, a new ioctl, and the
actual iteration and read-issuing logic. Error scrubbing is executed in

test-runner: pass kmemleak and kmsg to Cmd.run
test-runner.py orchestrates all of the ZTS executions. The `Cmd` object
manages these process, and its `run` method specifically invokes these
possibly long-running processes, possibly retrying in the event of a
timeout. Since its inception, memory leak detection using the kmemleak
infrastructure [1], and kernel logging [2] have been added to this run
mechanism.
However, the callback to cull a process beyond its timeout threshold,
`kill_cmd`, has evaded modernization by both of these changes. As a
result, this function fails to properly invoke `run`, leading to an
untrapped exception and unreported test failure.
This patch extends `kill_cmd` to receive these kernel devices through
the `options` parameter, and regularizes all the `.run` calls from
`Cmd`, and its subclasses, to accept that parameter.

Fix undefined behavior in spa_sync_props()
8eae2d214cfa53862833eeeda9a5c1e9d5ded47d caused Coverity to begin
complaining about "Improper use of negative value" in two places in
spa_sync_props() because Coverity correctly inferred from `prop ==
ZPOOL_PROP_INVAL` that prop could be -1 while both zpool_prop_to_name()
and zpool_prop_get_type() use it an array index, which is undefined
behavior.
Assuming that the system does not panic from an attempt to read invalid
memory, the case statement for ZPOOL_PROP_INVAL will ensure that only
user properties will reach this code when prop is ZPOOL_PROP_INVAL, such
that execution will continue safely. However, if we are unlucky enough
to read invalid memory, then the system will panic.
This issue predates the patch that caused coverity to begin complaining.
Thankfully, our userland tools do not pass nonsense to us, so this bug
should not be triggered unless a future userland tool attempts to set a
property that we do not understand.

Deny block cloning is dbuf size doesn't match BP size.
I don't know an easy way to shrink down dbuf size, so just deny block cloning
into dbufs that don't match our BP's size.
This fixes the following situation:
1. Create a small file, eg. 1kB of random bytes. Its dbuf will be 1kB.
2. Create a larger file, eg. 2kB of random bytes. Its dbuf will be 2kB.
3. Truncate the large file to 0. Its dbuf will remain 2kB.
4. Clone the small file into the large file. Small file's BP lsize is
1kB, but the large file's dbuf is 2kB.

pam: Fix "buffer overflow" in pam ZTS tests on F38
The pam ZTS tests were reporting a buffer overflow on F38, possibly
due to F38 now setting _FORTIFY_SOURCE=3 by default. gdb and
valgrind narrowed this down to a snprintf() buffer overflow in
zfs_key_config_modify_session_counter(). I'm not clear why this
particular snprintf() was being flagged as an overflow, but when
I replaced it with an asprintf(), the test passed reliably.

Enable the head_errlog feature to remove errors
In case check_filesystem() does not error out and does not report
an error, remove that error block from error lists and logs
without requiring a scrub. This can happen when the original file and
all snapshots/clones referencing it have been removed.
Otherwise zpool status will still report that "Permanent errors have
been detected..." without actually reporting any of them.
To implement this change the functions introduced in corrective
receive were modified to take into account the head_errlog feature.

corruption. Applications may be affected.

After this change:

attempt was made to correct the error. Applications are

Verify block pointers before writing them out
If a block pointer is corrupted (but the block containing it checksums
correctly, e.g. due to a bug that overwrites random memory), we can
often detect it before the block is read, with the `zfs_blkptr_verify()`
function, which is used in `arc_read()`, `zio_free()`, etc.
However, such corruption is not typically recoverable. To recover from
it we would need to detect the memory error before the block pointer is
written to disk.
This PR verifies BP's that are contained in indirect blocks and dnodes
before they are written to disk, in `dbuf_write_ready()`. This way,
we'll get a panic before the on-disk data is corrupted. This will help
us to diagnose what's causing the corruption, as well as being much
easier to recover from.
To minimize performance impact, only checks that can be done without
holding the spa_config_lock are performed.
Additionally, when corruption is detected, the raw words of the block
pointer are logged. (Note that `dprintf_bp()` is a no-op by default,
but if enabled it is not safe to use with invalid block pointers.)
