ZTS: Adopt OpenZFS test analysis script
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.

Implement large_dnode pool feature
Justification ------------- This feature adds support for variable length dnodes. Our motivation is to eliminate the overhead associated with using spill blocks. Spill blocks are used to store system attribute data (i.e. file metadata) that does not fit in the dnode's bonus buffer. By allowing a larger bonus buffer area the use of a spill block can be avoided. Spill blocks potentially incur an additional read I/O for every dnode in a dnode block. As a worst case example, reading 32 dnodes from a 16k dnode block and all of the spill blocks could issue 33 separate reads. Now suppose those dnodes have size 1024 and therefore don't need spill blocks. Then the worst case number of blocks read is reduced to from 33 to two--one per dnode block. In practice spill blocks may tend to be co-located on disk with the dnode blocks so the reduction in I/O would not be this drastic. In a badly fragmented pool, however, the improvement could be significant. ZFS-on-Linux systems that make heavy use of extended attributes would benefit from this feature. In particular, ZFS-on-Linux supports the xattr=sa dataset property which allows file extended attribute data to be stored in the dnode bonus buffer as an alternative to the traditional directory-based format. Workloads such as SELinux and the Lustre distributed filesystem often store enough xattr data to force spill bocks when xattr=sa is in effect. Large dnodes may therefore provide a performance benefit to such systems. Other use cases that may benefit from this feature include files with large ACLs and symbolic links with long target names. Furthermore, this feature may be desirable on other platforms in case future applications or features are developed that could make use of a larger bonus buffer area. Implementation -------------- The size of a dnode may be a multiple of 512 bytes up to the size of a dnode block (currently 16384 bytes). A dn_extra_slots field was added to the current on-disk dnode_phys_t structure to describe the size of the physical dnode on disk. The 8 bits for this field were taken from the zero filled dn_pad2 field. The field represents how many "extra" dnode_phys_t slots a dnode consumes in its dnode block. This convention results in a value of 0 for 512 byte dnodes which preserves on-disk format compatibility with older software. Similarly, the in-memory dnode_t structure has a new dn_num_slots field to represent the total number of dnode_phys_t slots consumed on disk. Thus dn->dn_num_slots is 1 greater than the corresponding dnp->dn_extra_slots. This difference in convention was adopted because, unlike on-disk structures, backward compatibility is not a concern for in-memory objects, so we used a more natural way to represent size for a dnode_t. The default size for newly created dnodes is determined by the value of a new "dnodesize" dataset property. By default the property is set to "legacy" which is compatible with older software. Setting the property to "auto" will allow the filesystem to choose the most suitable dnode size. Currently this just sets the default dnode size to 1k, but future code improvements could dynamically choose a size based on observed workload patterns. Dnodes of varying sizes can coexist within the same dataset and even within the same dnode block. For example, to enable automatically-sized dnodes, run # zfs set dnodesize=auto tank/fish The user can also specify literal values for the dnodesize property. These are currently limited to powers of two from 1k to 16k. The power-of-2 limitation is only for simplicity of the user interface. Internally the implementation can handle any multiple of 512 up to 16k, and consumers of the DMU API can specify any legal dnode value. The size of a new dnode is determined at object allocation time and stored as a new field in the znode in-memory structure. New DMU interfaces are added to allow the consumer to specify the dnode size that a newly allocated object should use. Existing interfaces are unchanged to avoid having to update every call site and to preserve compatibility with external consumers such as Lustre. The new interfaces names are given below. The versions of these functions that don't take a dnodesize parameter now just call the _dnsize() versions with a dnodesize of 0, which means use the legacy dnode size. New DMU interfaces: dmu_object_alloc_dnsize() dmu_object_claim_dnsize() dmu_object_reclaim_dnsize() New ZAP interfaces: zap_create_dnsize() zap_create_norm_dnsize() zap_create_flags_dnsize() zap_create_claim_norm_dnsize() zap_create_link_dnsize() The constant DN_MAX_BONUSLEN is renamed to DN_OLD_MAX_BONUSLEN. The spa_maxdnodesize() function should be used to determine the maximum bonus length for a pool. These are a few noteworthy changes to key functions: * The prototype for dnode_hold_impl() now takes a "slots" parameter. When the DNODE_MUST_BE_FREE flag is set, this parameter is used to ensure the hole at the specified object offset is large enough to hold the dnode being created. The slots parameter is also used to ensure a dnode does not span multiple dnode blocks. In both of these cases, if a failure occurs, ENOSPC is returned. Keep in mind, these failure cases are only possible when using DNODE_MUST_BE_FREE. If the DNODE_MUST_BE_ALLOCATED flag is set, "slots" must be 0. dnode_hold_impl() will check if the requested dnode is already consumed as an extra dnode slot by an large dnode, in which case it returns ENOENT. * The function dmu_object_alloc() advances to the next dnode block if dnode_hold_impl() returns an error for a requested object. This is because the beginning of the next dnode block is the only location it can safely assume to either be a hole or a valid starting point for a dnode. * dnode_next_offset_level() and other functions that iterate through dnode blocks may no longer use a simple array indexing scheme. These now use the current dnode's dn_num_slots field to advance to the next dnode in the block. This is to ensure we properly skip the current dnode's bonus area and don't interpret it as a valid dnode. zdb --- The zdb command was updated to display a dnode's size under the "dnsize" column when the object is dumped. For ZIL create log records, zdb will now display the slot count for the object. ztest ----- Ztest chooses a random dnodesize for every newly created object. The random distribution is more heavily weighted toward small dnodes to better simulate real-world datasets. Unused bonus buffer space is filled with non-zero values computed from the object number, dataset id, offset, and generation number. This helps ensure that the dnode traversal code properly skips the interior regions of large dnodes, and that these interior regions are not overwritten by data belonging to other dnodes. A new test visits each object in a dataset. It verifies that the actual dnode size matches what was stored in the ztest block tag when it was created. It also verifies that the unused bonus buffer space is filled with the expected data patterns. ZFS Test Suite -------------- Added six new large dnode-specific tests, and integrated the dnodesize property into existing tests for zfs allow and send/recv. Send/Receive ------------ ZFS send streams for datasets containing large dnodes cannot be received on pools that don't support the large_dnode feature. A send stream with large dnodes sets a DMU_BACKUP_FEATURE_LARGE_DNODE flag which will be unrecognized by an incompatible receiving pool so that the zfs receive will fail gracefully. While not implemented here, it may be possible to generate a backward-compatible send stream from a dataset containing large dnodes. The implementation may be tricky, however, because the send object record for a large dnode would need to be resized to a 512 byte dnode, possibly kicking in a spill block in the process. This means we would need to construct a new SA layout and possibly register it in the SA layout object. The SA layout is normally just sent as an ordinary object record. But if we are constructing new layouts while generating the send stream we'd have to build the SA layout object dynamically and send it at the end of the stream. For sending and receiving between pools that do support large dnodes, the drr_object send record type is extended with a new field to store the dnode slot count. This field was repurposed from unused padding in the structure. ZIL Replay ---------- The dnode slot count is stored in the uppermost 8 bits of the lr_foid field. The bits were unused as the object id is currently capped at 48 bits. Resizing Dnodes --------------- It should be possible to resize a dnode when it is dirtied if the current dnodesize dataset property differs from the dnode's size, but this functionality is not currently implemented. Clearly a dnode can only grow if there are sufficient contiguous unused slots in the dnode block, but it should always be possible to shrink a dnode. Growing dnodes may be useful to reduce fragmentation in a pool with many spill blocks in use. Shrinking dnodes may be useful to allow sending a dataset to a pool that doesn't support the large_dnode feature. Feature Reference Counting -------------------------- The reference count for the large_dnode pool feature tracks the number of datasets that have ever contained a dnode of size larger than 512 bytes. The first time a large dnode is created in a dataset the dataset is converted to an extensible dataset. This is a one-way operation and the only way to decrement the feature count is to destroy the dataset, even if the dataset no longer contains any large dnodes. The complexity of reference counting on a per-dnode basis was too high, so we chose to track it on a per-dataset basis similarly to the large_block feature.

Add zfs allow and zfs unallow support
ZFS allows for specific permissions to be delegated to normal users with the `zfs allow` and `zfs unallow` commands. In addition, non- privileged users should be able to run all of the following commands: * zpool [list | iostat | status | get] * zfs [list | get] Historically this functionality was not available on Linux. In order to add it the secpolicy_* functions needed to be implemented and mapped to the equivalent Linux capability. Only then could the permissions on the `/dev/zfs` be relaxed and the internal ZFS permission checks used. Even with this change some limitations remain. Under Linux only the root user is allowed to modify the namespace (unless it's a private namespace). This means the mount, mountpoint, canmount, unmount, and remount delegations cannot be supported with the existing code. It may be possible to add this functionality in the future. This functionality was validated with the cli_user and delegation test cases from the ZFS Test Suite. These tests exhaustively verify each of the supported permissions which can be delegated and ensures only an authorized user can perform it. Two minor bug fixes were required for test-running.py. First, the Timer() object cannot be safely created in a `try:` block when there is an unconditional `finally` block which references it. Second, when running as a normal user also check for scripts using the both the .ksh and .sh suffixes. Finally, existing users who are simulating delegations by setting group permissions on the /dev/zfs device should revert that customization when updating to a version with this change.

Add the ZFS Test Suite
Add the ZFS Test Suite and test-runner framework from illumos.
This is a continuation of the work done by Turbo Fredriksson to
port the ZFS Test Suite to Linux. While this work was originally
conceived as a stand alone project integrating it directly with
the ZoL source tree has several advantages:
* Allows the ZFS Test Suite to be packaged in zfs-test package.
* Facilitates easy integration with the CI testing.
* Users can locally run the ZFS Test Suite to validate ZFS.
This testing should ONLY be done on a dedicated test system
because the ZFS Test Suite in its current form is destructive.
* Allows the ZFS Test Suite to be run directly in the ZoL source
tree enabled developers to iterate quickly during development.
* Developers can easily add/modify tests in the framework as
features are added or functionality is changed. The tests
will then always be in sync with the implementation.
Full documentation for how to run the ZFS Test Suite is available
in the tests/README.md file.
Warning: This test suite is designed to be run on a dedicated test
system. It will make modifications to the system including, but
not limited to, the following.
* Adding new users
* Adding new groups
* Modifying the following /proc files:
* /proc/sys/kernel/core_pattern
* /proc/sys/kernel/core_uses_pid
* Creating directories under /
Notes:
* Not all of the test cases are expected to pass and by default
these test cases are disabled. The failures are primarily due
to assumption made for illumos which are invalid under Linux.
* When updating these test cases it should be done in as generic
a way as possible so the patch can be submitted back upstream.
Most existing library functions have been updated to be Linux
aware, and the following functions and variables have been added.
* Functions:
* is_linux - Used to wrap a Linux specific section.
* block_device_wait - Waits for block devices to be added to /dev/.
* Variables: Linux Illumos
* ZVOL_DEVDIR "/dev/zvol" "/dev/zvol/dsk"
* ZVOL_RDEVDIR "/dev/zvol" "/dev/zvol/rdsk"
* DEV_DSKDIR "/dev" "/dev/dsk"
* DEV_RDSKDIR "/dev" "/dev/rdsk"
* NEWFS_DEFAULT_FS "ext2" "ufs"
* Many of the disabled test cases fail because 'zfs/zpool destroy'
returns EBUSY. This is largely causes by the asynchronous nature
of device handling on Linux and is expected, the impacted test
cases will need to be updated to handle this.
* There are several test cases which have been disabled because
they can trigger a deadlock. A primary example of this is to
recursively create zpools within zpools. These tests have been
disabled until the root issue can be addressed.
* Illumos specific utilities such as (mkfile) should be added to
the tests/zfs-tests/cmd/ directory. Custom programs required by
the test scripts can also be added here.
* SELinux should be either is permissive mode or disabled when
running the tests. The test cases should be updated to conform
to a standard policy.
* Redundant test functionality has been removed (zfault.sh).
* Existing test scripts (zconfig.sh) should be migrated to use
the framework for consistency and ease of testing.
* The DISKS environment variable currently only supports loopback
devices because of how the ZFS Test Suite expects partitions to
be named (p1, p2, etc). Support must be added to generate the
correct partition name based on the device location and name.
* The ZFS Test Suite is part of the illumos code base at:
