* Provide macros for setting and getting blkptr birth timesGeorge Wilson2024-03-251-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There exist a couple of macros that are used to update the blkptr birth times but they can often be confusing. For example, the BP_PHYSICAL_BIRTH() macro will provide either the physical birth time if it is set or else return back the logical birth time. The complement to this macro is BP_SET_BIRTH() which will set the logical birth time and set the physical birth time if they are not the same. Consumers may get confused when they are trying to get the physical birth time and use the BP_PHYSICAL_BIRTH() macro only to find out that the logical birth time is what is actually returned. This change cleans up these macros and makes them symmetrical. The same functionally is preserved but the name is changed. Instead of calling BP_PHYSICAL_BIRTH(), consumer can now call BP_GET_BIRTH(). In additional to cleaning up this naming conventions, two new sets of macros are introduced -- BP_[SET|GET]_LOGICAL_BIRTH() and BP_[SET|GET]_PHYSICAL_BIRTH. These new macros allow the consumer to get and set the specific birth time. As part of the cleanup, the unused GRID macros have been removed and that portion of the blkptr are currently unused.

* Increase limit of redaction list by using spill blockPaul Dagnelie2023-08-261-0/+10
| | | | | | | | | | | | | | | | | | | | Currently redaction bookmarks and their associated redaction lists have a relatively low limit of 36 redaction snapshots. This is imposed by the number of snapshot GUIDs that fit in the bonus buffer of the redaction list object. While this is more than enough for most use cases, there are some limited cases where larger numbers would be useful to support. We tweak the redaction list creation code to use a spill block if the number of redaction snapshots is above the amount that would fit in the bonus buffer. We also make a small change to allow spill blocks to be use for types of data besides SA. In order to fully leverage this logic, we also change the redaction code to use vmem_alloc, to handle extremely large allocations if needed. Finally, small tweaks were made to the zfs commands and the test suite. Reviewed-by: Matthew Ahrens <[email protected]> Signed-off-by: Paul Dagnelie <[email protected]> Closes #15018
* nvpair: Constify string functionsRichard Yao2023-03-141-1/+1
| | | | | | | | | | | | | | After addressing coverity complaints involving `nvpair_name()`, the compiler started complaining about dropping const. This lead to a rabbit hole where not only `nvpair_name()` needed to be constified, but also `nvpair_value_string()`, `fnvpair_value_string()` and a few other static functions, plus variable pointers throughout the code. The result became a fairly big change, so it has been split out into its own patch.

* Prevent zevent list from consuming all of kernel memoryPaul Dagnelie2022-08-221-3/+10
| | | | | | | | | | | | | | | | | | | | There are a couple changes included here. The first is to introduce a cap on the size the ZED will grow the zevent list to. One million entries is more than enough for most use cases, and if you are overflowing that value, the problem needs to be addressed another way. The value is also tunable, for those who want the limit to be higher or lower. The other change is to add a kernel module parameter that allows snapshot creation/deletion to be exempted from the history logging; for most workloads, having these things logged is valuable, but for some workloads it produces large quantities of log spam and isn't especially helpful.

* Improve zpool status output, list all affected datasetsGeorge Amanakis2022-04-251-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix i/o error handling of livelists and zap iterationMatthew Ahrens2020-08-051-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pool-wide metadata is stored in the MOS (Meta Object Set). This metadata is stored in triplicate, in addition to any pool-level reduncancy (e.g. RAIDZ). However, if all 3+ copies of this metadata are not available, we can still get EIO/ECKSUM when reading from the MOS. If we encounter such an error in syncing context, we have typically already committed to making a change that we now can't do because of the corrupt/missing metadata. We typically "handle" this with a `VERIFY()` or `zfs_panic_recover()`. This prevents the system from continuing on in an undefined state, while minimizing the amount of error-handling code. However, there are some code paths that ignore these i/o errors, or `ASSERT()` that they don't happen. Since assertions are disabled on non-debug builds, they effectively ignore them as well. This can lead to ZFS continuing on in an incorrect state, potentially leading to on-disk inconsistencies. This commit adds handling for these i/o errors on MOS metadata, typically with a `VERIFY()`: * Handle error return from `zap_cursor_retrieve()` in 4 places in `dsl_deadlist.c`. * Handle error return from `zap_contains()` in `dsl_dir_hold_obj()`. Turns out this call isn't necessary because we can always call `zap_lookup()`. * Handle error return from `zap_lookup()` in `dsl_fs_ss_limit_check()`. * Handle error return from `zap_remove()` in `dsl_dir_rename_sync()`. * Handle error return from `zap_lookup()` in `dsl_dir_remove_livelist()`. * Handle error return from `dsl_process_sub_livelist()` in `spa_livelist_delete_cb()`. Additionally: * Augment the internal history log message for `zfs destroy` to note which method is used (e.g. bptree, livelist, or, synchronous) and the mintxg. * Correct a comment in `dbuf_init()`. * Correct indentation in `dsl_dir_remove_livelist()`.

* Add 'zfs wait' commandPaul Dagnelie2020-04-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | Add a mechanism to wait for delete queue to drain. When doing redacted send/recv, many workflows involve deleting files that contain sensitive data. Because of the way zfs handles file deletions, snapshots taken quickly after a rm operation can sometimes still contain the file in question, especially if the file is very large. This can result in issues for redacted send/recv users who expect the deleted files to be redacted in the send streams, and not appear in their clones. This change duplicates much of the zpool wait related logic into a zfs wait command, which can be used to wait until the internal deleteq has been drained. Additional wait activities may be added in the future.

| | | | | | | | | | | | | | | | | | | | | When there are many snapshots, calls to zfs_ioc_space_snaps() (e.g. from `zfs destroy -nv pool/fs@snap1%snap10000`) can be very slow, resulting in poor performance because we are holding the dp_config_rwlock the entire time, blocking spa_sync() from continuing. With around ten thousand snapshots, we've seen up to 500 seconds in this ioctl, iterating over up to 50,000,000 bpobjs, ~99% of which are the empty bpobj. By creating a fast path for zfs_ioc_space_snaps() handling of the empty_bpobj, we can achieve a ~5x performance improvement of this ioctl (when there are many snapshots, and the deadlist is mostly empty_bpobj's).

* Implement Redacted Send/ReceivePaul Dagnelie2019-06-191-62/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Redacted send/receive allows users to send subsets of their data to a target system. One possible use case for this feature is to not transmit sensitive information to a data warehousing, test/dev, or analytics environment. Another is to save space by not replicating unimportant data within a given dataset, for example in backup tools like zrepl. Redacted send/receive is a three-stage process. First, a clone (or clones) is made of the snapshot to be sent to the target. In this clone (or clones), all unnecessary or unwanted data is removed or modified. This clone is then snapshotted to create the "redaction snapshot" (or snapshots). Second, the new zfs redact command is used to create a redaction bookmark. The redaction bookmark stores the list of blocks in a snapshot that were modified by the redaction snapshot(s). Finally, the redaction bookmark is passed as a parameter to zfs send. When sending to the snapshot that was redacted, the redaction bookmark is used to filter out blocks that contain sensitive or unwanted information, and those blocks are not included in the send stream. When sending from the redaction bookmark, the blocks it contains are considered as candidate blocks in addition to those blocks in the destination snapshot that were modified since the creation_txg of the redaction bookmark. This step is necessary to allow the target to rehydrate data in the case where some blocks are accidentally or unnecessarily modified in the redaction snapshot. The changes to bookmarks to enable fast space estimation involve adding deadlists to bookmarks. There is also logic to manage the life cycles of these deadlists. The new size estimation process operates in cases where previously an accurate estimate could not be provided. In those cases, a send is performed where no data blocks are read, reducing the runtime significantly and providing a byte-accurate size estimate.

| | | | | | | | | | | | | | | | | | | | The boolean featureflags in use thus far in ZFS are extremely useful, but because they take advantage of the zap layer, more interesting data than just a true/false value can be stored in a featureflag. In redacted send/receive, this is used to store the list of redaction snapshots for a redacted dataset. This change adds the ability for ZFS to store types other than a boolean in a featureflag. The only other implemented type is a uint64_t array. It also modifies the interfaces around dataset features to accomodate the new capabilities, and adds a few new functions to increase encapsulation. This functionality will be used by the Redacted Send/Receive feature.

This operation copies all allocated regions of the device to be removed onto other devices, recording the mapping from old to new location. After the removal is complete, read and free operations to the removed (now "indirect") vdev must be remapped and performed at the new location on disk. The indirect mapping table is kept in memory whenever the pool is loaded, so there is minimal performance overhead when doing operations on the indirect vdev. The size of the in-memory mapping table will be reduced when its entries become "obsolete" because they are no longer used by any block pointers in the pool. An entry becomes obsolete when all the blocks that use it are freed. An entry can also become obsolete when all the snapshots that reference it are deleted, and the block pointers that reference it have been "remapped" in all filesystems/zvols (and clones). Whenever an indirect block is written, all the block pointers in it will be "remapped" to their new (concrete) locations if possible. This process can be accelerated by using the "zfs remap" command to proactively rewrite all indirect blocks that reference indirect (removed) vdevs. Note that when a device is removed, we do not verify the checksum of the data that is copied. This makes the process much faster, but if it were used on redundant vdevs (i.e. mirror or raidz vdevs), it would be possible to copy the wrong data, when we have the correct data on e.g. the other side of the mirror. At the moment, only mirrors and simple top-level vdevs can be removed and no removal is allowed if any of the top-level vdevs are raidz. Porting Notes: * Avoid zero-sized kmem_alloc() in vdev_compact_children(). The device evacuation code adds a dependency that vdev_compact_children() be able to properly empty the vdev_child array by setting it to NULL and zeroing vdev_children. Under Linux, kmem_alloc() and related functions return a sentinel pointer rather than NULL for zero-sized allocations. * Remove comment regarding "mpt" driver where zfs_remove_max_segment is initialized to SPA_MAXBLOCKSIZE. Change zfs_condense_indirect_commit_entry_delay_ticks to zfs_condense_indirect_commit_entry_delay_ms for consistency with most other tunables in which delays are specified in ms. * ZTS changes: Use set_tunable rather than mdb Use zpool sync as appropriate Use sync_pool instead of sync Kill jobs during test_removal_with_operation to allow unmount/export Don't add non-disk names such as "mirror" or "raidz" to $DISKS Use $TEST_BASE_DIR instead of /tmp Increase HZ from 100 to 1000 which is more common on Linux removal_multiple_indirection.ksh Reduce iterations in order to not time out on the code coverage builders. removal_resume_export: Functionally, the test case is correct but there exists a race where the kernel thread hasn't been fully started yet and is not visible. Wait for up to 1 second for the removal thread to be started before giving up on it. Also, increase the amount of data copied in order that the removal not finish before the export has a chance to fail. * MMP compatibility, the concept of concrete versus non-concrete devices has slightly changed the semantics of vdev_writeable(). Update mmp_random_leaf_impl() accordingly. * Updated dbuf_remap() to handle the org.zfsonlinux:large_dnode pool feature which is not supported by OpenZFS. * Added support for new vdev removal tracepoints. * Test cases removal_with_zdb and removal_condense_export have been intentionally disabled. When run manually they pass as intended, but when running in the automated test environment they produce unreliable results on the latest Fedora release. They may work better once the upstream pool import refectoring is merged into ZoL at which point they will be re-enabled.

This would greatly improve performance for channel programs that just gather information, as they won't have to wait for synching context anymore. === What is implemented? This feature introduces the following: - A new command line flag in "zfs program" to specify our intention to run in open context. (The -n option) - A new flag/option within the channel program ioctl which selects the context. - Appropriate error handling whenever we try a channel program in open-context that contains zfs.sync* expressions. - Documentation for the new feature in the manual pages. === How do we handle zfs.sync functions in open context? When such a function is found by the interpreter and we are running in open context we abort the script and we spit out a descriptive runtime error. For example, given the script below ... arg = ... fs = arg["argv"][1] err = zfs.sync.destroy(fs) msg = "destroying " .. fs .. " err=" .. err return msg if we run it in open context, we will get back the following error: Channel program execution failed: [string "channel program"]:3: running functions from the zfs.sync submodule requires passing sync=TRUE to lzc_channel_program() (i.e. do not specify the "-n" command line argument) stack traceback: [C]: in function 'destroy' [string "channel program"]:3: in main chunk === What about testing? We've introduced new wrappers for all channel program tests that run each channel program as both (startard & open-context) and expect the appropriate behavior depending on the program using the zfs.sync module.

The current patch completely gets rid of that code and changes the approach while keeping the behavior of that code path the same. Specifically, it puts a hold on the dataset/snapshot and gets its vfs resource reference directly, instead of linearly searching for it. If that reference exists we attempt to amount it. With the above change, it became obvious that the nvlist manipulations that we do (add_boolean and add_nvlist) take a significant amount of time ensuring uniqueness of every new element even though they don't have too. Thus, we updated the patch so those nvlists are not trying to enforce the uniqueness of their elements.

* Native Encryption for ZFS on LinuxTom Caputi2017-08-141-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change incorporates three major pieces: The first change is a keystore that manages wrapping and encryption keys for encrypted datasets. These commands mostly involve manipulating the new DSL Crypto Key ZAP Objects that live in the MOS. Each encrypted dataset has its own DSL Crypto Key that is protected with a user's key. This level of indirection allows users to change their keys without re-encrypting their entire datasets. The change implements the new subcommands "zfs load-key", "zfs unload-key" and "zfs change-key" which allow the user to manage their encryption keys and settings. In addition, several new flags and properties have been added to allow dataset creation and to make mounting and unmounting more convenient. The second piece of this patch provides the ability to encrypt, decyrpt, and authenticate protected datasets. Each object set maintains a Merkel tree of Message Authentication Codes that protect the lower layers, similarly to how checksums are maintained. This part impacts the zio layer, which handles the actual encryption and generation of MACs, as well as the ARC and DMU, which need to be able to handle encrypted buffers and protected data. The last addition is the ability to do raw, encrypted sends and receives. The idea here is to send raw encrypted and compressed data and receive it exactly as is on a backup system. This means that the dataset on the receiving system is protected using the same user key that is in use on the sending side. By doing so, datasets can be efficiently backed up to an untrusted system without fear of data being compromised.

Volumes, like filesystems, are limited by the zfs_max_recordsize=1M module option. * By default the maximum record size is limited to 1M by the module option zfs_max_recordsize. This value may be safely increased up to 16M which is the largest block size supported by the on-disk format. At the moment, 1M blocks clearly offer a significant performance improvement but the benefits of going beyond this for the majority of workloads are less clear. * The illumos version of this patch increased DMU_MAX_ACCESS to 32M. This was determined not to be large enough when using 16M blocks because the zfs_make_xattrdir() function will fail (EFBIG) when assigning a TX. This was immediately observed under Linux because all newly created files must have a security xattr created and that was failing. Therefore, we've set DMU_MAX_ACCESS to 64M. * On 32-bit platforms a hard limit of 1M is set for blocks due to the limited virtual address space.
