This fixes an oversight in the Direct I/O PR. There is nothing that
stops a process from manipulating the contents of a buffer for a
Direct I/O read while the I/O is in flight. This can lead checksum
verify failures. However, the disk contents are still correct, and this
would lead to false reporting of checksum validation failures.
To remedy this, all Direct I/O reads that have a checksum verification
failure are treated as suspicious. In the event a checksum validation
failure occurs for a Direct I/O read, then the I/O request will be
reissued though the ARC. This allows for actual validation to happen and
removes any possibility of the buffer being manipulated after the I/O
has been issued.
Just as with Direct I/O write checksum validation failures, Direct I/O
read checksum validation failures are reported though zpool status -d in
the DIO column. Also the zevent has been updated to have both:
1. dio_verify_wr -> Checksum verification failure for writes
2. dio_verify_rd -> Checksum verification failure for reads.
This allows for determining what I/O operation was the culprit for the
checksum verification failure. All DIO errors are reported only on the
top-level VDEV.
Even though FreeBSD can write protect pages (stable pages) it still has
the same issue as Linux with Direct I/O reads.
This commit updates the following:
1. Propogates checksum failures for reads all the way up to the
top-level VDEV.
2. Reports errors through zpool status -d as DIO.
3. Has two zevents for checksum verify errors with Direct I/O. One for
read and one for write.
4. Updates FreeBSD ABD code to also check for ABD_FLAG_FROM_PAGES and
handle ABD buffer contents validation the same as Linux.
5. Updated manipulate_user_buffer.c to also manipulate a buffer while a
Direct I/O read is taking place.
6. Adds a new ZTS test case dio_read_verify that stress tests the new
code.
7. Updated man pages.
8. Added an IMPLY statement to zio_checksum_verify() to make sure that
Direct I/O reads are not issued as speculative.
9. Removed self healing through mirror, raidz, and dRAID VDEVs for
Direct I/O reads.
This issue was first observed when installing a Windows 11 VM on a ZFS
dataset with the dataset property direct set to always. The zpool
devices would report checksum failures, but running a subsequent zpool
scrub would not repair any data and report no errors.

In a4b21eadec we added the zap_micro_max_size tuneable to raise the size
at which "micro" (single-block) ZAPs are upgraded to "fat" (multi-block)
ZAPs. Before this, a microZAP was limited to 128KiB, which was the old
largest block size. The side effect of raising the max size past 128KiB
is that it be stored in a large block, requiring the large_blocks
feature.
Unfortunately, this means that a backup stream created without the
--large-block (-L) flag to zfs send would split the microZAP block into
smaller blocks and send those, as is normal behaviour for large blocks.
This would be received correctly, but since microZAPs are limited to the
first block in the object by definition, the entries in the later blocks
would be inaccessible. For directory ZAPs, this gives the appearance of
files being lost.
This commit adds a feature flag, large_microzap, that must be enabled
for microZAPs to grow beyond 128KiB, and which will be activated the
first time that occurs. This feature is later checked when generating
the stream and if active, the send operation will abort unless
--large-block has also been requested.
Changing the limit still requires zap_micro_max_size to be changed. The
state of this flag effectively sets the upper value for this tuneable,
that is, if the feature is disabled, the tuneable will be clamped to
128KiB.
A stream flag is also added to ensure that the receiver also activates
its own feature flag upon receiving the stream. This is not strictly
necessary to _use_ the received microZAP, since it doesn't care how
large its block is, but it is required to send the microZAP object on,
otherwise the original problem occurs again.
Because it's difficult to reliably distinguish a microZAP from a fatZAP
from outside the ZAP code, and because it seems unlikely that most
users are affected (a fairly niche tuneable combined with what should be
an uncommon use of send), and for the sake of expediency, this change
activates the feature the first time a microZAP grows to use a large
block, and is never deactivated after that. This can be improved in the
future.
This commit changes nothing for existing pools that already have large
microZAPs. The feature will not be retroactively applied, but will be
activated the next time a microZAP grows past the limit.
Don't use large_blocks feature for enable/disable tests. The
large_microzap depends on large_blocks, so it gets enabled as a
dependency, breaking the test. Instead use feature "longname", which has
the exact same feature characteristics.

In some environments, just making the .zfs control dir hidden from sight
might not be enough. In particular, the following scenarios might
warrant not allowing access at all:
- old snapshots with wrong permissions/ownership
- old snapshots with exploitable setuid/setgid binaries
- old snapshots with sensitive contents
Introducing a new 'disabled' value that not only hides the control dir,
but prevents access to its contents by returning ENOENT solves all of
the above.
The new property value takes advantage of 'iuv' semantics ("ignore
unknown value") to automatically fall back to the old default value when
a pool is accessed by an older version of ZFS that doesn't yet know
about 'disabled' semantics.
I think that technically the zfs_dirlook change is enough to prevent
access, but preventing lookups and dir entries in an already opened .zfs
handle might also be a good idea to prevent races when modifying the
property at runtime.
Add zfs_snapshot_no_setuid parameter to control whether automatically
mounted snapshots have the setuid mount option set or not.
this could be considered a partial fix for one of the scenarios
mentioned in desired.

torvalds/linux@09022bc196 removes the flag, and the corresponding
SetPageError() and ClearPageError() macros, with no replacement offered.
Going back through the upstream history, use of this flag has been
gradually removed over the last year as part of the long tail of
converting everything to folios. Interesting tidbit comments from
torvalds/linux@29e9412b25 and torvalds/linux@420e05d0de suggest that
this flag has not been used meaningfully since page writeback failures
started being recorded in errseq_t instead (the whole "fsyncgate" thing,
~2017, around torvalds/linux@8ed1e46aaf).
Given that, it's possible that since perhaps Linux 4.13 we haven't been
getting anything by setting the flag. I don't know if that's true and/or
if there's something we should be doing instead, but my gut feel is that
its probably fine we only use the page cache as a proxy to allow mmap()
to work, rather than backing IO with it.
As such, I'm expecting that removing this will do no harm, but I'm
leaving it in for older kernels to maintain status quo, and if there is
an overall better way, that is left for a future change.

This patch adds the ability for zfs to support file/dir name up to 1023
bytes. This number is chosen so we can support up to 255 4-byte
characters. This new feature is represented by the new feature flag
feature@longname.
A new dataset property "longname" is also introduced to toggle longname
support for each dataset individually. This property can be disabled,
even if it contains longname files. In such case, new file cannot be
created with longname but existing longname files can still be looked
up.
Note that, to my knowledge native Linux filesystems don't support name
longer than 255 bytes. So there might be programs not able to work with
longname.
Note that NFS server may needs to use exportfs_get_name to reconnect
dentries, and the buffer being passed is limit to NAME_MAX+1 (256). So
NFS may not work when longname is enabled.
Note, FreeBSD vfs layer imposes a limit of 255 name lengh, so even
though we add code to support it here, it won't actually work.
