* Replace P2ALIGN with P2ALIGN_TYPED and delete P2ALIGN.chenqiuhao19972024-05-131-3/+5
| | | | | | | | | | | | | In P2ALIGN, the result would be incorrect when align is unsigned integer and x is larger than max value of the type of align. In that case, -(align) would be a positive integer, which means high bits would be zero and finally stay zero after '&' when align is converted to a larger integer type.

* Add prefetch property Brian Behlendorf2024-04-301-0/+11
| | | | | | | | | | | | | | | | | | | | | | ZFS prefetch is currently governed by the zfs_prefetch_disable tunable. However, this is a module-wide settings - if a specific dataset benefits from prefetch, while others have issue with it, an optimal solution does not exists. This commit introduce the "prefetch" tri-state property, which enable granular control (at dataset/volume level) for prefetching. This patch does not remove the zfs_prefetch_disable, which remains a system-wide switch for enable/disable prefetch. However, to avoid duplication, it would be preferable to deprecate and then remove the module tunable.

* Add slow disk diagnosis to ZEDDon Brady2024-04-291-0/+6
| | | | | | | | | | | | | | | | | | | | | Slow disk response times can be indicative of a failing drive. ZFS currently tracks slow I/Os (slower than zio_slow_io_ms) and generates events (ereport.fs.zfs.delay). However, no action is taken by ZED, like is done for checksum or I/O errors. This change adds slow disk diagnosis to ZED which is opt-in using new VDEV properties: VDEV_PROP_SLOW_IO_N VDEV_PROP_SLOW_IO_T If multiple VDEVs in a pool are undergoing slow I/Os, then it skips the zpool_vdev_degrade().

* Drop lying to the compiler in the fletcher4 code Rich Ercolani2023-03-247-20/+0
| | | | | | | | | | | | | | | | | | | This is probably the uncontroversial part of #13631, which fixes a real problem people are having. There's still things to improve in our code after this is merged, but it should stop the breakage that people have reported, where we lie about a type always being aligned and then pass in stack objects with no alignment requirement and hope for the best. Of course, our SIMD code was written with unaligned accesses, so it doesn't care if we drop this...but some auto-vectorized code that gcc emits sure does, since we told it it can assume they're aligned.

| | | | | | | | | | | | | | | | | | Currently calls to kfpu_begin() and kfpu_end() are split between the init() and fini() functions of the particular SIMD implementation. This was done in #14247 as an optimization measure for the ABD adapter. Unfortunately the split complicates FPU handling on platforms that use a local FPU state buffer, like Windows and macOS.

* Configure zed's diagnosis engine with vdev propertiesrob-wing2023-01-231-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce four new vdev properties: checksum_n checksum_t io_n io_t These properties can be used for configuring the thresholds of zed's diagnosis engine and are interpeted as <N> events in T <seconds>. When this property is set to a non-default value on a top-level vdev, those thresholds will also apply to its leaf vdevs. This behavior can be overridden by explicitly setting the property on the leaf vdev. Note that, these properties do not persist across vdev replacement. For this reason, it is advisable to set the property on the top-level vdev instead of the leaf vdev. The default values for zed's diagnosis engine (10 events, 600 seconds) remains unchanged.

* Cleanup of dead code suggested by Clang Static Analyzer (#14380)Richard Yao2023-01-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I recently gained the ability to run Clang's static analyzer on the linux kernel modules via a few hacks. This extended coverage to code that was previously missed since Clang's static analyzer only looked at code that we built in userspace. Running it against the Linux kernel modules built from my local branch produced a total of 72 reports against my local branch. Of those, 50 were reports of logic errors and 22 were reports of dead code. Since we already had cleaned up all of the previous dead code reports, I felt it would be a good next step to clean up these dead code reports. Clang did a further breakdown of the dead code reports into: Dead assignment 15 Dead increment 2 Dead nested assignment 5 The benefit of cleaning these up, especially in the case of dead nested assignment, is that they can expose places where our error handling is incorrect. A number of them were fairly straight forward. However several were not: In vdev_disk_physio_completion(), not only were we not using the return value from the static function vdev_disk_dio_put(), but nothing used it, so I changed it to return void and removed the existing (void) cast in the other area where we call it in addition to no longer storing it to a stack value. In FSE_createDTable(), the function is dead code. Its helper function FSE_freeDTable() is also dead code, as are the CPP definitions in `module/zstd/include/zstd_compat_wrapper.h`. We just delete it all. In zfs_zevent_wait(), we have an optimization opportunity. cv_wait_sig() returns 0 if there are waiting signals and 1 if there are none. The Linux SPL version literally returns `signal_pending(current) ? 0 : 1)` and FreeBSD implements the same semantics, we can just do `!cv_wait_sig()` in place of `signal_pending(current)` to avoid unnecessarily calling it again. zfs_setattr() on FreeBSD version did not have error handling issue because the code was removed entirely from FreeBSD version. The error is from updating the attribute directory's files. After some thought, I decided to propapage errors on it to userspace. In zfs_secpolicy_tmp_snapshot(), we ignore a lack of permission from the first check in favor of checking three other permissions. I assume this is intentional. In zfs_create_fs(), the return value of zap_update() was not checked despite setting an important version number. I see no backward compatibility reason to permit failures, so we add an assertion to catch failures. Interestingly, Linux is still using ASSERT(error == 0) from OpenSolaris while FreeBSD has switched to the improved ASSERT0(error) from illumos, although illumos has yet to adopt it here. ASSERT(error == 0) was used on Linux while ASSERT0(error) was used on FreeBSD since the entire file needs conversion and that should be the subject of another patch. dnode_move()'s issue was caused by us not having implemented POINTER_IS_VALID() on Linux. We have a stub in `include/os/linux/spl/sys/kmem_cache.h` for it, when it really should be in `include/os/linux/spl/sys/kmem.h` to be consistent with Illumos/OpenSolaris. FreeBSD put both `POINTER_IS_VALID()` and `POINTER_INVALIDATE()` in `include/os/freebsd/spl/sys/kmem.h`, so we copy what it did. Whenever a report was in platform-specific code, I checked the FreeBSD version to see if it also applied to FreeBSD, but it was only relevant a few times. Lastly, the patch that enabled Clang's static analyzer to be run on the Linux kernel modules needs more work before it can be put into a PR. I plan to do that in the future as part of the on-going static analysis work that I am doing.

* Micro-optimize fletcher4 calculationsRichard Yao2022-12-056-68/+36
| | | | | | | | | | | | | | | | | | | | | When processing abds, we execute 1 `kfpu_begin()`/`kfpu_end()` pair on every page in the abd. This is wasteful and slows down checksum performance versus what the benchmark claimed. We correct this by moving those calls to the init and fini functions. Also, we always check the buffer length against 0 before calling the non-scalar checksum functions. This means that we do not need to execute the loop condition for the first loop iteration. That allows us to micro-optimize the checksum calculations by switching to do-while loops. Note that we do not apply that micro-optimization to the scalar implementation because there is no check in `fletcher_4_incremental_native()`/`fletcher_4_incremental_byteswap()` against 0 sized buffers being passed.

* Convert some sprintf() calls to kmem_scnprintf()Richard Yao2022-11-281-2/+2
| | | | | | | | | | | | | | | | | | | These `sprintf()` calls are used repeatedly to write to a buffer. There is no protection against overflow other than reviewers explicitly checking to see if the buffers are big enough. However, such issues are easily missed during review and when they are missed, we would rather stop printing rather than have a buffer overflow, so we convert these functions to use `kmem_scnprintf()`. The Linux kernel provides an entire page for module parameters, so we are safe to write up to PAGE_SIZE. Removing `sprintf()` from these functions removes the last instances of `sprintf()` usage in our platform-independent kernel code. This improves XNU kernel compatibility because the XNU kernel does not support (removed support for?) `sprintf()`.

| | | | | | | | | | | | | | | | | | | | | Linux defaults to setting "failfast" on BIOs, so that the OS will not retry IOs that fail, and instead report the error to ZFS. In some cases, such as errors reported by the HBA driver, not the device itself, we would wish to retry rather than generating vdev errors in ZFS. This new property allows that. This introduces a per vdev option to disable the failfast option. This also introduces a global module parameter to define the failfast mask value.

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.

* Improve zpool status output, list all affected datasetsGeorge Amanakis2022-04-251-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | Originally it was thought it would be useful to split up the kmods by functionality. This would allow external consumers to only load what was needed. However, in practice we've never had a case where this functionality would be needed, and conversely managing multiple kmods can be awkward. Therefore, this change merges all but the spl.ko kmod in to a single zfs.ko kmod.

* log xattr=sa create/remove/update to ZILJitendra Patidar2022-02-221-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <[email protected]> Reviewed-by: Christian Schwarz <[email protected]> Reviewed-by: Ahelenia Ziemiańska <[email protected]> Reviewed-by: Ryan Moeller <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Jitendra Patidar <[email protected]> Closes #8768 Closes #9078
* Linux 5.16 compat: don't use XSTATE_XSAVE to save FPU stateAttila Fülöp2022-02-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Linux 5.16 moved XSTATE_XSAVE and XSTATE_XRESTORE out of our reach, so add our own XSAVE{,OPT,S} code and use it for Linux 5.16. Please note that this differs from previous behavior in that it won't handle exceptions created by XSAVE an XRSTOR. This is sensible for three reasons. - Exceptions during XSAVE and XRSTOR can only occur if the feature is not supported or enabled or the memory operand isn't aligned on a 64 byte boundary. If this happens something else went terribly wrong, and it may be better to stop execution. - Previously we just printed a warning and didn't handle the fault, this is arguable for the above reason. - All other *SAVE instruction also don't handle exceptions, so this at least aligns behavior. Finally add a test to catch such a regression in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | `configure` now accepts `--enable-asan` and `--enable-ubsan` switches which results in passing `-fsanitize=address` and `-fsanitize=undefined`, respectively, to the compiler. Those flags are enabled in GitHub workflows for ZTS and zloop. Errors reported by both instrumentations are corrected, except for: - Memory leak reporting is (temporarily) suppressed. The cost of fixing them is relatively high compared to the gains. - Checksum computing functions in `module/zcommon/zfs_fletcher*` have UBSan errors suppressed. It is completely impractical to enforce 64-byte payload alignment there due to performance impact. - There's no ASan heap poisoning in `module/zstd/lib/zstd.c`. A custom memory allocator is used there rendering that measure unfeasible. - Memory leaks detection has to be suppressed for `cmd/zvol_id`. `zvol_id` is run by udev with the help of `ptrace(2)`. Tracing is incompatible with memory leaks detection.

* Vdev Properties FeatureAllan Jude2021-11-303-14/+272
| | | | | | | | | | | | | | | | | | | | | | | | Add properties, similar to pool properties, to each vdev. This makes use of the existing per-vdev ZAP that was added as part of device evacuation/removal. A large number of read-only properties are exposed, many of the members of struct vdev_t, that provide useful statistics. Adds support for read-only "removing" vdev property. Adds the "allocating" property that defaults to "on" and can be set to "off" to prevent future allocations from that top-level vdev. Supports user-defined vdev properties. Includes support for properties.vdev in SYSFS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
