Fix lua stack overflow on recursive call to gsub() The `zfs program` subcommand invokes a LUA interpreter to run ZFS "channel programs". This interpreter runs in a constrained environment, with defined memory limits. The LUA stack (used for LUA functions that call each other) is allocated in the kernel's heap, and is limited by the `-m MEMORY-LIMIT` flag and the `zfs_lua_max_memlimit` module parameter. The C stack is used by certain LUA features that are implemented in C. The C stack is limited by `LUAI_MAXCCALLS=20`, which limits call depth. Some LUA C calls use more stack space than others, and `gsub()` uses an unusually large amount. With a programming trick, it can be invoked recursively using the C stack (rather than the LUA stack). This overflows the 16KB Linux kernel stack after about 11 iterations, less than the limit of 20. One solution would be to decrease `LUAI_MAXCCALLS`. This could be made to work, but it has a few drawbacks: 1. The existing test suite does not pass with `LUAI_MAXCCALLS=10`. 2. There may be other LUA functions that use a lot of stack space, and the stack space may change depending on compiler version and options. This commit addresses the problem by adding a new limit on the amount of free space (in bytes) remaining on the C stack while running the LUA interpreter: `LUAI_MINCSTACK=4096`. If there is less than this amount of stack space remaining, a LUA runtime error is generated.

[tests/functional/checksum]
Introduce BLAKE3 checksums as an OpenZFS feature This commit adds BLAKE3 checksums to OpenZFS, it has similar performance to Edon-R, but without the caveats around the latter. Homepage of BLAKE3: https://github.com/BLAKE3-team/BLAKE3 Wikipedia: https://en.wikipedia.org/wiki/BLAKE_(hash_function)#BLAKE3 Short description of Wikipedia: BLAKE3 is a cryptographic hash function based on Bao and BLAKE2, created by Jack O'Connor, Jean-Philippe Aumasson, Samuel Neves, and Zooko Wilcox-O'Hearn. It was announced on January 9, 2020, at Real World Crypto. BLAKE3 is a single algorithm with many desirable features (parallelism, XOF, KDF, PRF and MAC), in contrast to BLAKE and BLAKE2, which are algorithm families with multiple variants. BLAKE3 has a binary tree structure, so it supports a practically unlimited degree of parallelism (both SIMD and multithreading) given enough input. The official Rust and C implementations are dual-licensed as public domain (CC0) and the Apache License. Along with adding the BLAKE3 hash into the OpenZFS infrastructure a new benchmarking file called chksum_bench was introduced. When read it reports the speed of the available checksum functions.

Add block histogram to zdb The block histogram tracks the changes to psize, lsize and asize both in the count of the number of blocks (by blocksize) and the total length of all of the blocks for that blocksize. It also keeps a running total of the cumulative size of all of the blocks up to each size to help determine the size of caching SSDs to be added to zfs hardware deployments. The block history counts and lengths are summarized in bins which are powers of two. Even rows with counts of zero are printed. This change is accessed by specifying one of two options: zdb -bbb pool zdb -Pbbb pool The first version prints the table in fixed size columns. The second prints in "parseable" output that can be placed into a CSV file. Fixed Column, nicenum output sample: block psize lsize asize size Count Length Cum. Count Length Cum.

Add zstd support to zfs This PR adds two new compression types, based on ZStandard: - zstd: A basic ZStandard compression algorithm Available compression. Levels for zstd are zstd-1 through zstd-19, where the compression increases with every level, but speed decreases. - zstd-fast: A faster version of the ZStandard compression algorithm zstd-fast is basically a "negative" level of zstd. The compression decreases with every level, but speed increases. Available compression levels for zstd-fast: - zstd-fast-1 through zstd-fast-10 - zstd-fast-20 through zstd-fast-100 (in increments of 10) - zstd-fast-500 and zstd-fast-1000 For more information check the man page. Implementation details: Rather than treat each level of zstd as a different algorithm (as was done historically with gzip), the block pointer `enum zio_compress` value is simply zstd for all levels, including zstd-fast, since they all use the same decompression function. The compress= property (a 64bit unsigned integer) uses the lower 7 bits to store the compression algorithm (matching the number of bits used in a block pointer, as the 8th bit was borrowed for embedded block pointers). The upper bits are used to store the compression level. It is necessary to be able to determine what compression level was used when later reading a block back, so the concept used in LZ4, where the first 32bits of the on-disk value are the size of the compressed data (since the allocation is rounded up to the nearest ashift), was extended, and we store the version of ZSTD and the level as well as the compressed size. This value is returned when decompressing a block, so that if the block needs to be recompressed (L2ARC, nop-write, etc), that the same parameters will be used to result in the matching checksum. All of the internal ZFS code ( `arc_buf_hdr_t`, `objset_t`, `zio_prop_t`, etc.) uses the separated _compress and _complevel variables. Only the properties ZAP contains the combined/bit-shifted value. The combined value is split when the compression_changed_cb() callback is called, and sets both objset members (os_compress and os_complevel). The userspace tools all use the combined/bit-shifted value. Additional notes: zdb can now also decode the ZSTD compression header (flag -Z) and inspect the size, version and compression level saved in that header. For each record, if it is ZSTD compressed, the parameters of the decoded compression header get printed. ZSTD is included with all current tests and new tests are added as-needed. Per-dataset feature flags now get activated when the property is set. If a compression algorithm requires a feature flag, zfs activates the feature when the property is set, rather than waiting for the first block to be born. This is currently only used by zstd but can be extended as needed.

Remove dependency on sharetab file and refactor sharing logic == Motivation and Context The current implementation of 'sharenfs' and 'sharesmb' relies on the use of the sharetab file. The use of this file is os-specific and not required by linux or freebsd. Currently the code must maintain updates to this file which adds complexity and presents a significant performance impact when sharing many datasets. In addition, concurrently running 'zfs sharenfs' command results in missing entries in the sharetab file leading to unexpected failures. == Description This change removes the sharetab logic from the linux and freebsd implementation of 'sharenfs' and 'sharesmb'. It still preserves an os-specific library which contains the logic required for sharing NFS or SMB. The following entry points exist in the vastly simplified libshare library: - sa_enable_share -- shares a dataset but may not commit the change - sa_disable_share -- unshares a dataset but may not commit the change - sa_is_shared -- determine if a dataset is shared - sa_commit_share -- notify NFS/SMB subsystem to commit the shares - sa_validate_shareopts -- determine if sharing options are valid The sa_commit_share entry point is provided as a performance enhancement and is not required. The sa_enable_share/sa_disable_share may commit the share as part of the implementation. Libshare provides a framework for both NFS and SMB but some operating systems may not fully support these protocols or all features of the protocol. NFS Operation: For linux, libshare updates /etc/exports.d/zfs.exports to add and remove shares and then commits the changes by invoking 'exportfs -r'. This file, is automatically read by the kernel NFS implementation which makes for better integration with the NFS systemd service. For FreeBSD, libshare updates /etc/zfs/exports to add and remove shares and then commits the changes by sending a SIGHUP to mountd. SMB Operation: For linux, libshare adds and removes files in /var/lib/samba/usershares by calling the 'net' command directly. There is no need to commit the changes. FreeBSD does not support SMB. == Performance Results To test sharing performance we created a pool with an increasing number of datasets and invoked various zfs actions that would enable and disable sharing. The performance testing was limited to NFS sharing. The following tests were performed on an 8 vCPU system with 128GB and a pool comprised of 4 50GB SSDs: Scale testing: - Share all filesystems in parallel -- zfs sharenfs=on <dataset> & - Unshare all filesystems in parallel -- zfs sharenfs=off <dataset> & Functional testing: - share each filesystem serially -- zfs share -a - unshare each filesystem serially -- zfs unshare -a - reset sharenfs property and unshare -- zfs inherit -r sharenfs <pool> For 'zfs sharenfs=on' scale testing we saw an average reduction in time of 89.43% and for 'zfs sharenfs=off' we saw an average reduction in time of 83.36%. Functional testing also shows a huge improvement: - zfs share -- 97.97% reduction in time - zfs unshare -- 96.47% reduction in time - zfs inhert -r sharenfs -- 99.01% reduction in time Reviewed-by: Matt Ahrens <matt@delphix.com> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: Ryan Moeller <ryan@ixsystems.com> Reviewed-by: Bryant G.

Distributed Spare (dRAID) Feature This patch adds a new top-level vdev type called dRAID, which stands for Distributed parity RAID. This pool configuration allows all dRAID vdevs to participate when rebuilding to a distributed hot spare device. This can substantially reduce the total time required to restore full parity to pool with a failed device. A dRAID pool can be created using the new top-level `draid` type. Like `raidz`, the desired redundancy is specified after the type: `draid[1,2,3]`. No additional information is required to create the pool and reasonable default values will be chosen based on the number of child vdevs in the dRAID vdev. zpool create <pool> draid[1,2,3] <vdevs...> Unlike raidz, additional optional dRAID configuration values can be provided as part of the draid type as colon separated values. This allows administrators to fully specify a layout for either performance or capacity reasons. The supported options include: zpool create <pool> \ draid[<parity>][:<data>d][:<children>c][:<spares>s] \ <vdevs...> - draid[parity] - Parity level (default 1) - draid[:<data>d] - Data devices per group (default 8) - draid[:<children>c] - Expected number of child vdevs - draid[:<spares>s] - Distributed hot spares (default 0) Abbreviated example `zpool status` output for a 68 disk dRAID pool with two distributed spares using special allocation classes. ``` pool: tank state: ONLINE config: NAME STATE READ WRITE CKSUM slag7 ONLINE 0 0 0 draid2:8d:68c:2s-0 ONLINE 0 0 0 L0 ONLINE 0 0 0 L1 ONLINE 0 0 0 ...

Add "compatibility" property for zpool feature sets Property to allow sets of features to be specified; for compatibility with specific versions / releases / external systems. Influences the behavior of 'zpool upgrade' and 'zpool create'. Initial man page changes and test cases included. Brief synopsis: zpool create -o compatibility=off|legacy|file[,file...] pool vdev... compatibility = off : disable compatibility mode (enable all features) compatibility = legacy : request that no features be enabled compatibility = file[,file...] : read features from specified files. Only features present in *all* files will be enabled on the resulting pool. Filenames may be absolute, or relative to /etc/zfs/compatibility.d or /usr/share/zfs/compatibility.d (/etc checked first). Only affects zpool create, zpool upgrade and zpool status. ABI changes in libzfs: * New function "zpool_load_compat" to load and parse compat sets. * Add "zpool_compat_status_t" typedef for compatibility parse status. * Add ZPOOL_PROP_COMPATIBILITY to the pool properties enum * Add ZPOOL_STATUS_COMPATIBILITY_ERR to the pool status enum An initial set of base compatibility sets are included in cmd/zpool/compatibility.d, and the Makefile for cmd/zpool is modified to install these in $pkgdatadir/compatibility.d and to create symbolic links to a reasonable set of aliases.

Improve zpool status output, list all affected datasets Currently, determining which datasets are affected by corruption is a manual process. The primary difficulty in reporting the list of affected snapshots is that since the error was initially found, the snapshot where the error originally occurred in, may have been deleted. To solve this issue, we add the ID of the head dataset of the original snapshot which the error was detected in, to the stored error report. Then any time a filesystem is deleted, the errors associated with it are deleted as well. Any time a clone promote occurs, we modify reports associated with the original head to refer to the new head. The stored error reports are identified by this head ID, the birth time of the block which the error occurred in, as well as some information about the error itself are also stored. Once this information is stored, we can find the set of datasets affected by an error by walking back the list of snapshots in the given head until we find one with the appropriate birth txg, and then traverse through the snapshots of the clone family, terminating a branch if the block was replaced in a given snapshot. Then we report this information back to libzfs, and to the zpool status command, where it is displayed as follows: pool: test state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-8A scan: scrub repaired 0B in 00:00:00 with 800 errors on Fri Dec 3 08:27:57 2021 config: NAME STATE READ WRITE CKSUM test ONLINE 0 0 0 sdb ONLINE 0 0 1.58K errors: Permanent errors have been detected in the following files: test@1:/test.0.0 /test/test.0.0 /test/1clone/test.0.0 A new feature flag is introduced to mark the presence of this change, as well as promotion and backwards compatibility logic. This is an updated version of #9175. Rebase required fixing the tests, updating the ABI of libzfs, updating the man pages, fixing bugs, fixing the error returns, and updating the old on-disk error logs to the new format when activating the feature.

Add device rebuild feature The device_rebuild feature enables sequential reconstruction when resilvering. Mirror vdevs can be rebuilt in LBA order which may more quickly restore redundancy depending on the pools average block size, overall fragmentation and the performance characteristics of the devices. However, block checksums cannot be verified as part of the rebuild thus a scrub is automatically started after the sequential resilver completes. The new '-s' option has been added to the `zpool attach` and `zpool replace` command to request sequential reconstruction instead of healing reconstruction when resilvering. zpool attach -s <pool> <existing vdev> <new vdev> zpool replace -s <pool> <old vdev> <new vdev> The `zpool status` output has been updated to report the progress of sequential resilvering in the same way as healing resilvering. The one notable difference is that multiple sequential resilvers may be in progress as long as they're operating on different top-level vdevs. The `zpool wait -t resilver` command was extended to wait on sequential resilvers. From this perspective they are no different than healing resilvers. Sequential resilvers cannot be supported for RAIDZ, but are compatible with the dRAID feature being developed. As part of this change the resilver_restart_* tests were moved in to the functional/replacement directory. Additionally, the replacement tests were renamed and extended to verify both resilvering and rebuilding.

[tests/functional/compression]
Fix L2ARC reads when compressed ARC disabled When reading compressed blocks from the L2ARC, with compressed ARC disabled, arc_hdr_size() returns LSIZE rather than PSIZE, but the actual read is PSIZE. This causes l2arc_read_done() to compare the checksum against the wrong size, resulting in checksum failure. This manifests as an increase in the kstat l2_cksum_bad and the read being retried from the main pool, making the L2ARC ineffective. Add new L2ARC tests with Compressed ARC enabled/disabled Blocks are handled differently depending on the state of the zfs_compressed_arc_enabled tunable. If a block is compressed on-disk, and compressed_arc is enabled: - the block is read from disk - It is NOT decompressed - It is added to the ARC in its compressed form - l2arc_write_buffers() may write it to the L2ARC (as is) - l2arc_read_done() compares the checksum to the BP (compressed) However, if compressed_arc is disabled: - the block is read from disk - It is decompressed - It is added to the ARC (uncompressed) - l2arc_write_buffers() will use l2arc_apply_transforms() to recompress the block, before writing it to the L2ARC - l2arc_read_done() compares the checksum to the BP (compressed) - l2arc_read_done() will use l2arc_untransform() to uncompress it This test writes out a test file to a pool consisting of one disk and one cache device, then randomly reads from it. Since the arc_max in the tests is low, this will feed the L2ARC, and result in reads from the L2ARC. We compare the value of the kstat l2_cksum_bad before and after to determine if any blocks failed to survive the trip through the L2ARC.

Add zstd support to zfs This PR adds two new compression types, based on ZStandard: - zstd: A basic ZStandard compression algorithm Available compression. Levels for zstd are zstd-1 through zstd-19, where the compression increases with every level, but speed decreases. - zstd-fast: A faster version of the ZStandard compression algorithm zstd-fast is basically a "negative" level of zstd. The compression decreases with every level, but speed increases. Available compression levels for zstd-fast: - zstd-fast-1 through zstd-fast-10 - zstd-fast-20 through zstd-fast-100 (in increments of 10) - zstd-fast-500 and zstd-fast-1000 For more information check the man page. Implementation details: Rather than treat each level of zstd as a different algorithm (as was done historically with gzip), the block pointer `enum zio_compress` value is simply zstd for all levels, including zstd-fast, since they all use the same decompression function. The compress= property (a 64bit unsigned integer) uses the lower 7 bits to store the compression algorithm (matching the number of bits used in a block pointer, as the 8th bit was borrowed for embedded block pointers). The upper bits are used to store the compression level. It is necessary to be able to determine what compression level was used when later reading a block back, so the concept used in LZ4, where the first 32bits of the on-disk value are the size of the compressed data (since the allocation is rounded up to the nearest ashift), was extended, and we store the version of ZSTD and the level as well as the compressed size. This value is returned when decompressing a block, so that if the block needs to be recompressed (L2ARC, nop-write, etc), that the same parameters will be used to result in the matching checksum. All of the internal ZFS code ( `arc_buf_hdr_t`, `objset_t`, `zio_prop_t`, etc.) uses the separated _compress and _complevel variables. Only the properties ZAP contains the combined/bit-shifted value. The combined value is split when the compression_changed_cb() callback is called, and sets both objset members (os_compress and os_complevel). The userspace tools all use the combined/bit-shifted value. Additional notes: zdb can now also decode the ZSTD compression header (flag -Z) and inspect the size, version and compression level saved in that header. For each record, if it is ZSTD compressed, the parameters of the decoded compression header get printed. ZSTD is included with all current tests and new tests are added as-needed. Per-dataset feature flags now get activated when the property is set. If a compression algorithm requires a feature flag, zfs activates the feature when the property is set, rather than waiting for the first block to be born. This is currently only used by zstd but can be extended as needed.

EIO caused by encryption + recursive gang Encrypted blocks can not have 3 DVAs, because they use the space of the 3rd DVA for the IV+salt. zio_write_gang_block() takes this into account, setting `gbh_copies` to no more than 2 in this case. Gang members BP's do not have the X (encrypted) bit set (nor do they have the DMU level and type fields set), because encryption is not handled at this level. The gang block is reassembled, and then encryption (and compression) are handled. To check if this gang block is encrypted, the code in zio_write_gang_block() checks `pio->io_bp`. This is normally fine, because the block that's being ganged is typically the encrypted BP. The problem is that if there is "recursive ganging", where a gang member is itself a gang block, then when zio_write_gang_block() is called to create a gang block for a gang member, `pio->io_bp` is the gang member's BP, which doesn't have the X bit set, so the number of DVA's is not restricted to 2. It should instead be looking at the the "gang leader", i.e. the top-level gang block, to determine how many DVA's can be used, to avoid a "NDVA's inversion" (where a child has more DVA's than its parent). gang leader BP: X (encrypted) bit set, 2 DVA's, IV+salt in 3rd DVA's space: ``` DVA[0]=<1:...:100400> DVA[1]=<0:...:100400> salt=... iv=... [L0 ZFS plain file] fletcher4 uncompressed encrypted LE gang unique double size=100000L/100000P birth=... fill=1 cksum=... ``` leader's GBH contains a BP with gang bit set and 3 DVA's: ``` DVA[0]=<1:...:55600> DVA[1]=<0:...:55600> [L0 unallocated] fletcher4 uncompressed unencrypted LE contiguous unique double size=55600L/55600P birth=... fill=0 cksum=... DVA[0]=<1:...:55600> DVA[1]=<0:...:55600> [L0 unallocated] fletcher4 uncompressed unencrypted LE contiguous unique double size=55600L/55600P birth=... fill=0 cksum=... DVA[0]=<1:...:55600> DVA[1]=<0:...:55600> DVA[2]=<1:...:200> [L0 unallocated] fletcher4 uncompressed unencrypted LE gang unique double size=55400L/55400P birth=... fill=0 cksum=... ``` On nondebug bits, having the 3rd DVA in the gang block works for the most part, because it's true that all 3 DVA's are available in the gang member BP (in the GBH). However, for accounting purposes, gang block DVA's ASIZE include all the space allocated below them, i.e. the 512-byte gang block header (GBH) as well as the gang members below that. We see that above where the gang leader BP is 1MB logical (and after compression: 0x`100000P`), but the ASIZE of each DVA is 2 sectors (1KB) more than 1MB (0x`100400`). Since thre are 3 copies of a block below it, we increment the ATIME of the 3rd DVA of the gang leader by the space used by the 3rd DVA of the child (1 sector, in this case). But there isn't really a 3rd DVA of the parent; the salt is stored in place of the 3rd DVA's ASIZE. So when zio_write_gang_member_ready() increments the parent's BP's `DVA[2]`'s ASIZE, it's actually incrementing the parent's salt. When we later try to read the encrypted recursively-ganged block, the salt doesn't match what we used to write it, so MAC verification fails and we get an EIO. ``` zio_encrypt(): encrypted 515/2/0/403 salt: 25 25 bb 9d ad d6 cd 89 zio_decrypt(): decrypting 515/2/0/403 salt: 26 25 bb 9d ad d6 cd 89 ``` This commit addresses the problem by not increasing the number of copies of the GBH beyond 2 (even for non-encrypted blocks). This simplifies the logic while maintaining the ability to traverse all metadata (including gang blocks) even if one copy is lost. (Note that 3 copies of the GBH will still be created if requested, e.g. for `copies=3` or MOS blocks.) Additionally, the code that increments the parent's DVA's ASIZE is made to check the parent DVA's NDVAS even on nondebug bits. So if there's a similar bug in the future, it will cause a panic when trying to write, rather than corrupting the parent BP and causing an error when reading.

[tests/functional/raidz]
Distributed Spare (dRAID) Feature This patch adds a new top-level vdev type called dRAID, which stands for Distributed parity RAID. This pool configuration allows all dRAID vdevs to participate when rebuilding to a distributed hot spare device. This can substantially reduce the total time required to restore full parity to pool with a failed device. A dRAID pool can be created using the new top-level `draid` type. Like `raidz`, the desired redundancy is specified after the type: `draid[1,2,3]`. No additional information is required to create the pool and reasonable default values will be chosen based on the number of child vdevs in the dRAID vdev. zpool create <pool> draid[1,2,3] <vdevs...> Unlike raidz, additional optional dRAID configuration values can be provided as part of the draid type as colon separated values. This allows administrators to fully specify a layout for either performance or capacity reasons. The supported options include: zpool create <pool> \ draid[<parity>][:<data>d][:<children>c][:<spares>s] \ <vdevs...> - draid[parity] - Parity level (default 1) - draid[:<data>d] - Data devices per group (default 8) - draid[:<children>c] - Expected number of child vdevs - draid[:<spares>s] - Distributed hot spares (default 0) Abbreviated example `zpool status` output for a 68 disk dRAID pool with two distributed spares using special allocation classes. ``` pool: tank state: ONLINE config: NAME STATE READ WRITE CKSUM slag7 ONLINE 0 0 0 draid2:8d:68c:2s-0 ONLINE 0 0 0 L0 ONLINE 0 0 0 L1 ONLINE 0 0 0 ...

These options are leverages by zloop.sh to test a wide range of dRAID configurations. -K draid|raidz|random - kind of RAID to test -D <value> - dRAID data drives per group -S <value> - dRAID distributed hot spares -R <value> - RAID parity (raidz or dRAID) The zpool_create, zpool_import, redundancy, replacement and fault test groups have all been updated provide test coverage for the dRAID feature.

[tests/functional/redundancy]
Fix dRAID self-healing short columns When dRAID performs a normal read operation only the data columns in the raid map are read from disk. This is enough information to calculate the checksum, verify it, and return the needed data to the application. It's only in the event of a checksum failure that the additional parity and any empty columns must be read since they are required for parity reconstruction. Reading these additional columns is handled by vdev_raidz_read_all() which calls vdev_draid_map_alloc_empty() to expand the raid_map_t and submit IOs for the missing columns. This all works correctly, but it fails to account for any "short" columns. These are data columns which are padded with a empty skip sector at the end. Since that empty sector is not needed for a normal read it's not read when columns is first read from disk. However, like the parity and empty columns the skip sector is needed to perform reconstruction. The fix is to mark any "short" columns as never being read by clearing the rc_tried flag when expanding the raid_map_t. This will cause the entire column to re-read from disk in the event of a checksum failure allowing the self-healing functionality to repair the block. Note that this only effects the self-healing feature because when scrubbing a pool the parity, data, and empty columns are all read initially to verify their contents. Furthermore, only blocks which contain "short" columns would be effected, and only when the memory backing the skip sector wasn't already zeroed out. This change extends the existing redundancy_raidz.ksh test case to verify self-healing (as well as resilver and scrub). Then applies the same test case to dRAID with a slightly modified version of the test script called redundancy_draid.ksh. The unused variable combrec was also removed from both test cases.

Scrub mirror children without BPs When scrubbing a raidz/draid pool, which contains a replacing or sparing mirror with multiple online children, only one child will be read. This is not normally a serious concern because the DTL records are used to determine where a good copy of the data is. As long as the data can be read from one child the mirror vdev will use it to repair gaps in any of its children. Furthermore, even if the data which was read is corrupt the raidz code will detect this and issue its own repair I/O to correct the damage in the mirror vdev. However, in the scenario where the DTL is wrong due to silent data corruption (say due to overwriting one child) and the scrub happens to read from a child with good data, then the other damaged mirror child will not be detected nor repaired. While this is possible for both raidz and draid vdevs, it's most pronounced when using draid. This is because by default the zed will sequentially rebuild a draid pool to a distributed spare, and the distributed spare half of the mirror is always preferred since it delivers better performance. This means the damaged half of the mirror will go undetected even after scrubbing. For system administrations this behavior is non-intuitive and in a worst case scenario could result in the only good copy of the data being unknowingly detached from the mirror. This change resolves the issue by reading all replacing/sparing mirror children when scrubbing. When the BP isn't available for verification, then compare the data buffers from each child. They must all be identical, if not there's silent damage and an error is returned to prompt the top-level vdev to issue a repair I/O to rewrite the data on all of the mirror children. Since we can't tell which child was wrong a checksum error is logged against the replacing or sparing mirror vdev.

Fix dRAID sequential resilver silent damage handling This change addresses two distinct scenarios which are possible when performing a sequential resilver to a dRAID pool with vdevs that contain silent unknown damage. Which in this circumstance took the form of the devices being intentionally overwritten with zeros. However, it could also result from a device returning incorrect data while a sequential resilver was in progress. Scenario 1) A sequential resilver is performed while all of the dRAID vdevs are ONLINE and there is silent damage present on the vdev being resilvered. In this case, nothing will be repaired by vdev_raidz_io_done_reconstruct_known_missing() because rc->rc_error isn't set on any of the raid columns. To address this vdev_draid_io_start_read() has been updated to always mark the resilvering column as ESTALE for sequential resilver IO. Scenario 2) Multiple columns contain silent damage for the same block and a sequential resilver is performed. In this case it's impossible to generate the correct data from parity unless all of the damaged columns are being sequentially resilvered (and thus only good data is used to generate parity). This is as expected and there's nothing which can be done about it. However, we need to be careful not to make to situation worse. Since we can't verify the data is actually good without a checksum, we must only repair the devices which are being sequentially resilvered. Otherwise, an incorrect repair to a device which previously contained good data could effectively lock in the damage and make reconstruction impossible. A check for this was added to vdev_raidz_io_done_verified() along with a new test case. Lastly, this change updates the redundancy_draid_spare1 and redundancy_draid_spare3 test cases to be more representative of normal dRAID replacement operation. Specifically, what we care about is that the scrub run after a sequential resilver does not find additional blocks which need repair. This would indicate the sequential resilver failed to rebuild a section of one of the devices. Note also the tests were switched to using the verify_pool() function which still checks for checksum errors.

[tests/functional/replacement]
Add device rebuild feature The device_rebuild feature enables sequential reconstruction when resilvering. Mirror vdevs can be rebuilt in LBA order which may more quickly restore redundancy depending on the pools average block size, overall fragmentation and the performance characteristics of the devices. However, block checksums cannot be verified as part of the rebuild thus a scrub is automatically started after the sequential resilver completes. The new '-s' option has been added to the `zpool attach` and `zpool replace` command to request sequential reconstruction instead of healing reconstruction when resilvering. zpool attach -s <pool> <existing vdev> <new vdev> zpool replace -s <pool> <old vdev> <new vdev> The `zpool status` output has been updated to report the progress of sequential resilvering in the same way as healing resilvering. The one notable difference is that multiple sequential resilvers may be in progress as long as they're operating on different top-level vdevs. The `zpool wait -t resilver` command was extended to wait on sequential resilvers. From this perspective they are no different than healing resilvers. Sequential resilvers cannot be supported for RAIDZ, but are compatible with the dRAID feature being developed. As part of this change the resilver_restart_* tests were moved in to the functional/replacement directory. Additionally, the replacement tests were renamed and extended to verify both resilvering and rebuilding.

log xattr=sa create/remove/update to ZIL As such, there are no specific synchronous semantics defined for the xattrs. But for xattr=on, it does log to ZIL and zil_commit() is done, if sync=always is set on dataset. This provides sync semantics for xattr=on with sync=always set on dataset. For the xattr=sa implementation, it doesn't log to ZIL, so, even with sync=always, xattrs are not guaranteed to be synced before xattr call returns to caller. So, xattr can be lost if system crash happens, before txg carrying xattr transaction is synced. This change adds xattr=sa logging to ZIL on xattr create/remove/update and xattrs are synced to ZIL (zil_commit() done) for sync=always. This makes xattr=sa behavior similar to xattr=on. Implementation notes: The actual logging is fairly straight-forward and does not warrant additional explanation. However, it has been 14 years since we last added new TX types to the ZIL [1], hence this is the first time we do it after the introduction of zpool features. Therefore, here is an overview of the feature activation and deactivation workflow: 1. The feature must be enabled. Otherwise, we don't log the new record type. This ensures compatibility with older software. 2. The feature is activated per-dataset, since the ZIL is per-dataset. 3. If the feature is enabled and dataset is not for zvol, any append to the ZIL chain will activate the feature for the dataset. Likewise for starting a new ZIL chain. 4. A dataset that doesn't have a ZIL chain has the feature deactivated. We ensure (3) by activating on the first zil_commit() after the feature was enabled. Since activating the features requires waiting for txg sync, the first zil_commit() after enabling the feature will be slower than usual. The downside is that this is really a conservative approximation: even if we never append a 'TX_SETSAXATTR' to the ZIL chain, we pay the penalty for feature activation. The upside is that the user is in control of when we pay the penalty, i.e., upon enabling the feature. We ensure (4) by hooking into zil_sync(), where ZIL destroy actually happens. One more piece on feature activation, since it's spread across multiple functions: zil_commit() zil_process_commit_list() if lwb == NULL // first zil_commit since zil_open zil_create() if no log block pointer in ZIL header: if feature enabled and not active: // CASE 1 enable, COALESCE txg wait with dmu_tx that allocated the log block else // log block was allocated earlier than this zil_open if feature enabled and not active: // CASE 2 enable, EXPLICIT txg wait else // already have an in-DRAM LWB if feature enabled and not active: // this happens when we enable the feature after zil_create // CASE 3 enable, EXPLICIT txg wait [1] https://github.com/illumos/illumos-gate/commit/da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0 Reviewed-by: Matthew Ahrens <mahrens@delphix.com> Reviewed-by: Christian Schwarz <christian.schwarz@nutanix.com> Reviewed-by: Ahelenia Ziemiańska <nabijaczleweli@nabijaczleweli.xyz> Reviewed-by: Ryan Moeller <freqlabs@FreeBSD.org> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Jitendra Patidar <jitendra.patidar@nutanix.com> Closes #8768 Closes #9078

Trim L2ARC The l2arc_evict() function is responsible for evicting buffers which reference the next bytes of the L2ARC device to be overwritten. Teach this function to additionally TRIM that vdev space before it is overwritten if the device has been filled with data. This is done by vdev_trim_simple() which trims by issuing a new type of TRIM, TRIM_TYPE_SIMPLE. We also implement a "Trim Ahead" feature. It is a zfs module parameter, expressed in % of the current write size. This trims ahead of the current write size. A minimum of 64MB will be trimmed. The default is 0 which disables TRIM on L2ARC as it can put significant stress to underlying storage devices. To enable TRIM on L2ARC we set l2arc_trim_ahead > 0. We also implement TRIM of the whole cache device upon addition to a pool, pool creation or when the header of the device is invalid upon importing a pool or onlining a cache device. This is dependent on l2arc_trim_ahead > 0. TRIM of the whole device is done with TRIM_TYPE_MANUAL so that its status can be monitored by zpool status -t. We save the TRIM state for the whole device and the time of completion on-disk in the header, and restore these upon L2ARC rebuild so that zpool status -t can correctly report them. Whole device TRIM is done asynchronously so that the user can export of the pool or remove the cache device while it is trimming (ie if it is too slow). We do not TRIM the whole device if persistent L2ARC has been disabled by l2arc_rebuild_enabled = 0 because we may not want to lose all cached buffers (eg we may want to import the pool with l2arc_rebuild_enabled = 0 only once because of memory pressure). If persistent L2ARC has been disabled by setting the module parameter l2arc_rebuild_blocks_min_l2size to a value greater than the size of the cache device then the whole device is trimmed upon creation or import of a pool if l2arc_trim_ahead > 0.

Cross-platform xattr user namespace compatibility ZFS on Linux originally implemented xattr namespaces in a way that is incompatible with other operating systems. On illumos, xattrs do not have namespaces. Every xattr name is visible. FreeBSD has two universally defined namespaces: EXTATTR_NAMESPACE_USER and EXTATTR_NAMESPACE_SYSTEM. The system namespace is used for protected FreeBSD-specific attributes such as MAC labels and pnfs state. These attributes have the namespace string "freebsd:system:" prefixed to the name in the encoding scheme used by ZFS. The user namespace is used for general purpose user attributes and obeys normal access control mechanisms. These attributes have no namespace string prefixed, so xattrs written on illumos are accessible in the user namespace on FreeBSD, and xattrs written to the user namespace on FreeBSD are accessible by the same name on illumos. Linux has several xattr namespaces. On Linux, ZFS encodes the namespace in the xattr name for every namespace, including the user namespace. As a consequence, an xattr in the user namespace with the name "foo" is stored by ZFS with the name "user.foo" and therefore appears on FreeBSD and illumos to have the name "user.foo" rather than "foo". Conversely, none of the xattrs written on FreeBSD or illumos are accessible on Linux unless the name happens to be prefixed with one of the Linux xattr namespaces, in which case the namespace is stripped from the name. This makes xattrs entirely incompatible between Linux and other platforms. We want to make the encoding of user namespace xattrs compatible across platforms. A critical requirement of this compatibility is for xattrs from existing pools from FreeBSD and illumos to be accessible by the same names in the user namespace on Linux. It is also necessary that existing pools with xattrs written by Linux retain access to those xattrs by the same names on Linux. Making user namespace xattrs from Linux accessible by the correct names on other platforms is important. The handling of other namespaces is not required to be consistent. Add a fallback mechanism for listing and getting xattrs to treat xattrs as being in the user namespace if they do not match a known prefix. Do not allow setting or getting xattrs with a name that is prefixed with one of the namespace names used by ZFS on supported platforms. Allow choosing between legacy illumos and FreeBSD compatibility and legacy Linux compatibility with a new tunable. This facilitates replication and migration of pools between hosts with different compatibility needs. The tunable controls whether or not to prefix the namespace to the name. If the xattr is already present with the alternate prefix, remove it so only the new version persists. By default the platform's existing convention is used.

Add L2ARC arcstats for MFU/MRU buffers and buffer content type Currently the ARC state (MFU/MRU) of cached L2ARC buffer and their content type is unknown. Knowing this information may prove beneficial in adjusting the L2ARC caching policy. This commit adds L2ARC arcstats that display the aligned size (in bytes) of L2ARC buffers according to their content type (data/metadata) and according to their ARC state (MRU/MFU or prefetch). It also expands the existing evict_l2_eligible arcstat to differentiate between MFU and MRU buffers. L2ARC caches buffers from the MRU and MFU lists of ARC. Upon caching a buffer, its ARC state (MRU/MFU) is stored in the L2 header (b_arcs_state). The l2_m{f,r}u_asize arcstats reflect the aligned size (in bytes) of L2ARC buffers according to their ARC state (based on b_arcs_state). We also account for the case where an L2ARC and ARC cached MRU or MRU_ghost buffer transitions to MFU. The l2_prefetch_asize reflects the alinged size (in bytes) of L2ARC buffers that were cached while they had the prefetch flag set in ARC. This is dynamically updated as the prefetch flag of L2ARC buffers changes. When buffers are evicted from ARC, if they are determined to be L2ARC eligible then their logical size is recorded in evict_l2_eligible_m{r,f}u arcstats according to their ARC state upon eviction. Persistent L2ARC: When committing an L2ARC buffer to a log block (L2ARC metadata) its b_arcs_state and prefetch flag is also stored. If the buffer changes its arcstate or prefetch flag this is reflected in the above arcstats. However, the L2ARC metadata cannot currently be updated to reflect this change. Example: L2ARC caches an MRU buffer. L2ARC metadata and arcstats count this as an MRU buffer. The buffer transitions to MFU. The arcstats are updated to reflect this. Upon pool re-import or on/offlining the L2ARC device the arcstats are cleared and the buffer will now be counted as an MRU buffer, as the L2ARC metadata were not updated. Bug fix: - If l2arc_noprefetch is set, arc_read_done clears the L2CACHE flag of an ARC buffer. However, prefetches may be issued in a way that arc_read_done() is bypassed. Instead, move the related code in l2arc_write_eligible() to account for those cases too. Also add a test and update manpages for l2arc_mfuonly module parameter, and update the manpages and code comments for l2arc_noprefetch. Move persist_l2arc tests to l2arc.
