* Silence 'make checkbashisms'Brian Behlendorf2020-08-202-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit d2bce6d03 added the 'make checkbashisms' target but did not resolve all of the bashisms in the scripts. This commit doesn't resolve them all either but it does fix up a few, and it excludes the others so 'make checkstyle' no longer prints warnings. It's a small step in the right direction. * Dracut is Linux specific and itself depends on bash. Therefore all dracut support scripts can be bash specific, update their shebang accordingly. * zed-functions.sh, zfs-import, zfs-mount, zfs-zed, smart paxcheck.sh, make_gitrev.sh - these scripts were excuded from the check until they can be updated and properly tested. * zfsunlock - only whole values for sleep are allowed. * vdev_id - removed unneeded locals; use && instead of -a. * dkms.mkconf, dkms.postbuil - use || instead of -o.

* Add zstd support to zfsMichael Niewöhner2020-08-203-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add zfs_gitrev.h to the distributed sourcesArvind Sankar2020-07-221-1/+29
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 109d2c931020 ("Move zfs_gitrev.h to build directory") stopped distributing zfs_gitrev.h, as it is a generated file. Add it back, with some changes in behavior. Change the logic for gitrev as follows - if the source tree is a git repository, the behavior for build is unchanged. For make dist, append -dist to the git tag in the distributed version of zfs_gitrev.h. - otherwise, check if the source tree contains zfs_gitrev.h, and use it if so, falling back to "unknown" if it doesn't exist. - clean it only in make maintainer-clean, so we don't remove it from the source tree on make clean or make distclean. This allows disted sources to track what git tag they originally came from, with the -dist suffix indicating that the code wasn't built directly from git and so might contain additional changes beyond the git tag.

* Move zfs_gitrev.h to build directoryArvind Sankar2020-06-242-46/+0
| | | | | | | | | | | | | | | | | | | | | | Currently an out-of-tree build does not work with read-only source directory because zfs_gitrev.h can't be created. Move this file to the build directory, which is more appropriate for a generated file, and drop the dist-hook for zfs_gitrev.h. There is no need to distribute this file since it will be regenerated as part of the compilation in any case. scripts/make_gitrev.sh tries to avoid updating zfs_gitrev.h if there has been no change, however this doesn't cover the case when the source directory is not in git: in that case zfs_gitrev.h gets overwritten even though it's always "unknown". Simplify the logic to always write out a new version of zfs_gitrev.h, compare against the old and overwrite only if different. This is now simple enough to just include in the Makefile, so drop the script.

* bash scripts: use /usr/bin/env for bash shebangsGraham Christensen2020-02-103-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not all systems / distros have a `/bin/bash`, and these scripts are more difficult to run at development time. For example, my system is NixOS which doesn't have a /bin/bash. This is not a problem for NixOS building ZFS as a package: the build environment automatically replaces these shebangs with corrected paths. The problem is much more annoying at development time: either the scripts don't run, or I correct them for my local machine and deal with a perpetually dirty work tree. Before committing this patch I confirmed there are existing scripts which use `/usr/bin/env` to locate bash, so I am thinking this is a safe transformation. There are a handful of other shebangs in this repository which don't work on my system. This patch is useful on its own specifically for `commitcheck.sh`, otherwise I can't validate my commits before submission. Here are the remaining shebangs which NixOS systems won't have: 1274 #!/bin/ksh -p 91 #!/bin/ksh 89 #! /bin/ksh -p 2 #!/bin/sed -f 1 #!/usr/bin/perl -w 1 #!/usr/bin/ksh 1 #!/bin/nawk -f plus this which will create an invalid shebang in `tests/zfs-tests/tests/functional/mv_files/mv_files_common.kshlib`: echo "#!/bin/ksh" > $TEST_BASE_DIR/exitsZero.ksh I chose to leave those alone for now, and gauge the interest in this much smaller patch first. The fixes for these are easy enough by simply using `/usr/bin/env ksh`: 91 #!/bin/ksh 1 #!/usr/bin/ksh The fix for the other set is much trickier. Quoting the GNU coreutils manual: Most operating systems (e.g. GNU/Linux, BSDs) treat all text after the first space as a single argument. When using env in a script it is thus not possible to specify multiple arguments. and not all `env`'s support arguments. Mine (GNU Coreutils 8.31) does, though this feature is new since April 2018, GNU Coreutils 8.30: https://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=668306ed86c8c79b0af0db8b9c882654ebb66db2 and worse, requires the -S argument: -S, --split-string=S process and split S into separate arguments; used to pass multiple arguments on shebang lines Example: $ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "sort -nr" /nix/[...]-coreutils-8.31/bin/env: ‘sort -nr’: No such file or directory /nix/[...]-coreutils-8.31/bin/env: use -[v]S to pass options in shebang lines $ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "-S sort -nr" 2 1 GNU Coreutils says FreeBSD's `env` does, though I wonder if FreeBSD's would be unhappy with the `-S`: https://www.gnu.org/software/coreutils/manual/html_node/env-invocation.html#env-invocation BusyBox v1.30.1 does not, and does not have a `-S`-like option: $ seq 1 2 | $(nix-build '<nixpkgs>' -A busybox)/bin/env "sort -nr" env: can't execute 'sort -nr': No such file or directory Toybox 0.8.1 also does not, and also does not have a `-S` option: $ seq 1 2 | $(nix-build '<nixpkgs>' -A toybox)/bin/env "sort -nr" env: exec sort -nr: No such file or directory --- At any rate, if this patch merges and the remaining ~1,500 are updated, the much larger patch should probably include a checkstyle-like test asserting all new shebangs use `/usr/bin/env`. I also don't mind dealing with NixOS weirdness if the project would prefer that.

* OpenZFS 9689 - zfs range lock code should not be zpl-specificMatt Ahrens2018-10-111-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ZFS range locking code in zfs_rlock.c/h depends on ZPL-specific data structures, specifically znode_t. However, it's also used by the ZVOL code, which uses a "dummy" znode_t to pass to the range locking code. We should clean this up so that the range locking code is generic and can be used equally by ZPL and ZVOL, and also can be used by future consumers that may need to run in userland (libzpool) as well as the kernel. Porting notes: * Added missing sys/avl.h include to sys/zfs_rlock.h. * Removed 'dbuf is within the locked range' ASSERTs from dmu_sync(). This was needed because ztest does not yet use a locked_range_t. * Removed "Approved by:" tag requirement from OpenZFS commit check to prevent needless warnings when integrating changes which has not been merged to illumos. * Reverted free_list range lock changes which were originally needed to defer the cv_destroy() which was called immediately after cv_broadcast(). With d2733258 this should be safe but if not we may need to reintroduce this logic. * Reverts: The following two commits were reverted and squashed in to this change in order to make it easier to apply OpenZFS 9689. - d88895a0, which removed the dummy znode from zvol_state - e3a07cd0, which updated ztest to use range locks * Preserved optimized rangelock comparison function. Preserved the rangelock free list. The cv_destroy() function will block waiting for all processes in cv_wait() to be scheduled and drop their reference. This is done to ensure it's safe to free the condition variable. However, blocking while holding the rl->rl_lock mutex can result in a deadlock on Linux. A free list is introduced to defer the cv_destroy() and kmem_free() until after the mutex is released.

* Create /proc/sys/kernel/spl/gitrev with git hashMatthew Ahrens2018-10-082-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing mechanisms for determining what code is running in the kernel do not always correctly report the git hash. The versions reported there do not reflect changes made since `configure` was run (i.e. incremental builds do not update the version) and they are misleading if git tags are not set up properly. This applies to `modinfo zfs`, `dmesg`, and `/sys/module/zfs/version`. There are complicated requirements on how the existing version is generated. Therefore we are leaving that alone, and adding a new mechanism to record and retrieve the git hash: `cat /proc/sys/kernel/spl/gitrev` The gitrev is re-generated at compile time, when running `make` (including for incremental builds). The value is the output of `git describe` (or "unknown" if not in a git repo or there are uncommitted changes). We're also removing /proc/sys/kernel/spl/version, which was never very useful.

* Direct IO supportBrian Behlendorf2018-08-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Direct IO via the O_DIRECT flag was originally introduced in XFS by IRIX for database workloads. Its purpose was to allow the database to bypass the page and buffer caches to prevent unnecessary IO operations (e.g. readahead) while preventing contention for system memory between the database and kernel caches. On Illumos, there is a library function called directio(3C) that allows user space to provide a hint to the file system that Direct IO is useful, but the file system is free to ignore it. The semantics are also entirely a file system decision. Those that do not implement it return ENOTTY. Since the semantics were never defined in any standard, O_DIRECT is implemented such that it conforms to the behavior described in the Linux open(2) man page as follows. 1. Minimize cache effects of the I/O. By design the ARC is already scan-resistant which helps mitigate the need for special O_DIRECT handling. Data which is only accessed once will be the first to be evicted from the cache. This behavior is in consistent with Illumos and FreeBSD. Future performance work may wish to investigate the benefits of immediately evicting data from the cache which has been read or written with the O_DIRECT flag. Functionally this behavior is very similar to applying the 'primarycache=metadata' property per open file. 2. O_DIRECT _MAY_ impose restrictions on IO alignment and length. No additional alignment or length restrictions are imposed. 3. O_DIRECT _MAY_ perform unbuffered IO operations directly between user memory and block device. No unbuffered IO operations are currently supported. In order to support features such as transparent compression, encryption, and checksumming a copy must be made to transform the data. 4. O_DIRECT _MAY_ imply O_DSYNC (XFS). O_DIRECT does not imply O_DSYNC for ZFS. Callers must provide O_DSYNC to request synchronous semantics. 5. O_DIRECT _MAY_ disable file locking that serializes IO operations. Applications should avoid mixing O_DIRECT and normal IO or mmap(2) IO to the same file. This is particularly true for overlapping regions. All I/O in ZFS is locked for correctness and this locking is not disabled by O_DIRECT. However, concurrently mixing O_DIRECT, mmap(2), and normal I/O on the same file is not recommended. This change is implemented by layering the aops->direct_IO operations on the existing AIO operations. Code already existed in ZFS on Linux for bypassing the page cache when O_DIRECT is specified.

* ZTS: Adopt OpenZFS test analysis scriptBrian Behlendorf2018-06-202-2/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adopt and extend the OpenZFS ZTS results analysis script for use with ZFS on Linux. This allows for automatic analysis of tests which may be skipped for a variety or reasons or which are not entirely reliable. In addition to the list of 'known' failures, which have been updated for ZFS on Linux, there in a new 'maybe' section. This mapping include tests which might be correctly skipped depending on the test environment. This may be because of a missing dependency or lack of required kernel support. This list also includes tests which normally pass but might on occasion fail for a harmless reason. The script was also extended include a reason for why a given test might be skipped or may fail. The reason will be included after the test in the "results other than PASS that are expected" section. For failures it is preferable to set the reason to the GitHub issue number and for skipped tests several generic reasons are available. You may also specify a custom reason if needed. All tests were added back in to the linux.run file even if they are expected to failed. There is value in running tests which may not pass, the expected results for these tests has been encoded in the new analysis script. All tests which were disabled because they ran more slowly on a 32-bit system have been re-enabled. Developers working on 32-bit systems should assess what it reasonable for their environment. The unnecessary dependency on physical block devices was removed for the checksum, grow_pool, and grow_replicas test groups so they are no longer skipped. Updated the filetest_001_pos test case to run properly now that it is enabled and moved the grow tests in to a single directory.
