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.

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.

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.

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.

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.

[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.

File incorrectly zeroed when receiving incremental stream that toggles -L Background: By increasing the recordsize property above the default of 128KB, a filesystem may have "large" blocks. By default, a send stream of such a filesystem does not contain large WRITE records, instead it decreases objects' block sizes to 128KB and splits the large blocks into 128KB blocks, allowing the large-block filesystem to be received by a system that does not support the `large_blocks` feature. A send stream generated by `zfs send -L` (or `--large-block`) preserves the large block size on the receiving system, by using large WRITE records. When receiving an incremental send stream for a filesystem with large blocks, if the send stream's -L flag was toggled, a bug is encountered in which the file's contents are incorrectly zeroed out. The contents of any blocks that were not modified by this send stream will be lost. "Toggled" means that the previous send used `-L`, but this incremental does not use `-L` (-L to no-L); or that the previous send did not use `-L`, but this incremental does use `-L` (no-L to -L). Changes: This commit addresses the problem with several changes to the semantics of zfs send/receive: 1. "-L to no-L" incrementals are rejected. If the previous send used `-L`, but this incremental does not use `-L`, the `zfs receive` will fail with this error message: incremental send stream requires -L (--large-block), to match previous receive. 2. "no-L to -L" incrementals are handled correctly, preserving the smaller (128KB) block size of any already-received files that used large blocks on the sending system but were split by `zfs send` without the `-L` flag. 3. A new send stream format flag is added, `SWITCH_TO_LARGE_BLOCKS`. This feature indicates that we can correctly handle "no-L to -L" incrementals. This flag is currently not set on any send streams. In the future, we intend for incremental send streams of snapshots that have large blocks to use `-L` by default, and these streams will also have the `SWITCH_TO_LARGE_BLOCKS` feature set. This ensures that streams from the default use of `zfs send` won't encounter the bug mentioned above, because they can't be received by software with the bug. Implementation notes: To facilitate accessing the ZPL's generation number, `zfs_space_delta_cb()` has been renamed to `zpl_get_file_info()` and restructured to fill in a struct with ZPL-specific info including owner and generation. In the "no-L to -L" case, if this is a compressed send stream (from `zfs send -cL`), large WRITE records that are being written to small (128KB) blocksize files need to be decompressed so that they can be written split up into multiple blocks. The zio pipeline will recompress each smaller block individually. A new test case, `send-L_toggle`, is added, which tests the "no-L to -L" case and verifies that we get an error for the "-L to no-L" case.

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.

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.
