Note that the ioctl and property will remain, but have no functionality.
This allows older software to fail gracefully if it attempts to use

UNMAP/TRIM support is a frequently-requested feature to help
prevent performance from degrading on SSDs and on various other
SAN-like storage back-ends. By issuing UNMAP/TRIM commands for
sectors which are no longer allocated the underlying device can
often more efficiently manage itself.
This TRIM implementation is modeled on the `zpool initialize`
feature which writes a pattern to all unallocated space in the
pool. The new `zpool trim` command uses the same vdev_xlate()
code to calculate what sectors are unallocated, the same per-
vdev TRIM thread model and locking, and the same basic CLI for
a consistent user experience. The core difference is that
instead of writing a pattern it will issue UNMAP/TRIM commands
for those extents.
The zio pipeline was updated to accommodate this by adding a new
ZIO_TYPE_TRIM type and associated spa taskq. This new type makes
is straight forward to add the platform specific TRIM/UNMAP calls
to vdev_disk.c and vdev_file.c. These new ZIO_TYPE_TRIM zios are
handled largely the same way as ZIO_TYPE_READs or ZIO_TYPE_WRITEs.
This makes it possible to largely avoid changing the pipieline,
one exception is that TRIM zio's may exceed the 16M block size
limit since they contain no data.
In addition to the manual `zpool trim` command, a background
automatic TRIM was added and is controlled by the 'autotrim'
property. It relies on the exact same infrastructure as the
manual TRIM. However, instead of relying on the extents in a
metaslab's ms_allocatable range tree, a ms_trim tree is kept
per metaslab. When 'autotrim=on', ranges added back to the
ms_allocatable tree are also added to the ms_free tree. The
ms_free tree is then periodically consumed by an autotrim
thread which systematically walks a top level vdev's metaslabs.
Since the automatic TRIM will skip ranges it considers too small
there is value in occasionally running a full `zpool trim`. This
may occur when the freed blocks are small and not enough time
was allowed to aggregate them. An automatic TRIM and a manual
`zpool trim` may be run concurrently, in which case the automatic
TRIM will yield to the manual TRIM.

Almost all of the Python code in the respository has been updated
to be compatibile with Python 2.6, Python 3.4, or newer. The only
exceptions are arc_summery3.py which requires Python 3, and pyzfs
which requires at least Python 2.7. This allows us to maintain a
single version of the code and support most default versions of
python. This change does the following:
* Sets the default shebang for all Python scripts to python3. If
only Python 2 is available, then at install time scripts which
are compatible with Python 2 will have their shebangs replaced
with /usr/bin/python. This is done for compatibility until
Python 2 goes end of life. Since only the installed versions
are changed this means Python 3 must be installed on the system
for test-runner when testing in-tree.
* Added --with-python=<2|3|3.4,etc> configure option which sets
the PYTHON environment variable to target a specific python
version. By default the newest installed version of Python
will be used or the preferred distribution version when
creating pacakges.
* Fixed --enable-pyzfs configure checks so they are run when
--enable-pyzfs=check and --enable-pyzfs=yes.
* Enabled pyzfs for Python 3.4 and newer, which is now supported.
* Renamed pyzfs package to python<VERSION>-pyzfs and updated to
install in the appropriate site location. For example, when
building with --with-python=3.4 a python34-pyzfs will be
created which installs in /usr/lib/python3.4/site-packages/.
* Renamed the following python scripts according to the Fedora
guidance for packaging utilities in /bin
- dbufstat.py -> dbufstat
- arcstat.py -> arcstat
- arc_summary.py -> arc_summary
- arc_summary3.py -> arc_summary3
* Updated python-cffi package name. On CentOS 6, CentOS 7, and
Amazon Linux it's called python-cffi, not python2-cffi. For
Python3 it's called python3-cffi or python3x-cffi.
* Install one version of arc_summary. Depending on the version
of Python available install either arc_summary2 or arc_summary3
as arc_summary. The user output is only slightly different.

When using "zfs destroy" on a dataset that is using "sharenfs=on" and
has been automatically exported (by libzfs), the dataset will not be
automatically unexported as it should be. This workflow appears to have
been broken by this commit: 3fd3e56cfd
In that change, the "zfs_unmount" function was modified to use the
"mnt.mnt_special" field when determining the mount point that is being
unmounted, rather than "mnt.mnt_mountp".
As a result, when "mntpt" is passed into "zfs_unshare_proto", it's value
is now the dataset name rather than the mountpoint. Thus, when this
value is used with the "is_shared" function (via "zfs_unshare_proto") it
will not find a match (since that function assumes it'll be passed the
mountpoint) and incorrectly reports that the dataset is not shared.
This can be easily reproduced with the following commands:
$ sudo zpool create tank xvdb
$ sudo zfs create -o sharenfs=on tank/fish
$ sudo zfs destroy tank/fish
$ sudo zfs list -r tank
NAME USED AVAIL REFER MOUNTPOINT
tank 97.5K 7.27G 24K /tank
$ sudo exportfs
/tank/fish <world>
$ sudo cat /etc/dfs/sharetab
/tank/fish - nfs rw,crossmnt
At this point, the "tank/fish" filesystem doesn't exist, but it's still
listed as exported when looking at "exportfs" and "/etc/dfs/sharetab".
Also note, this change brings us back in-sync with the illumos code, as
it pertains to this one line; on illumos, "mnt.mnt_mountp" is used.

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.

Issue #7741Closes#7742
While the autoexpand property may seem like a small feature it
depends on a significant amount of system infrastructure. Enough
of that infrastructure is now in place that with a few modifications
for Linux it can be supported.
Auto-expand works as follows; when a block device is modified
(re-sized, closed after being open r/w, etc) a change uevent is
generated for udev. The ZED, which is monitoring udev events,
passes the change event along to zfs_deliver_dle() if the disk
or partition contains a zfs_member as identified by blkid.
From here the device is matched against all imported pool vdevs
using the vdev_guid which was read from the label by blkid. If
a match is found the ZED reopens the pool vdev. This re-opening
is important because it allows the vdev to be briefly closed so
the disk partition table can be re-read. Otherwise, it wouldn't
be possible to report the maximum possible expansion size.
Finally, if the property autoexpand=on a vdev expansion will be
attempted. After performing some sanity checks on the disk to
verify that it is safe to expand, the primary partition (-part1)
will be expanded and the partition table updated. The partition
is then re-opened (again) to detect the updated size which allows
the new capacity to be used.
In order to make all of the above possible the following changes
were required:
* Updated the zpool_expand_001_pos and zpool_expand_003_pos tests.
These tests now create a pool which is layered on a loopback,
scsi_debug, and file vdev. This allows for testing of non-
partitioned block device (loopback), a partition block device
(scsi_debug), and a file which does not receive udev change
events. This provided for better test coverage, and by removing
the layering on ZFS volumes there issues surrounding layering
one pool on another are avoided.
* zpool_find_vdev_by_physpath() updated to accept a vdev guid.
This allows for matching by guid rather than path which is a
more reliable way for the ZED to reference a vdev.
* Fixed zfs_zevent_wait() signal handling which could result
in the ZED spinning when a signal was not handled.
* Removed vdev_disk_rrpart() functionality which can be abandoned
in favor of kernel provided blkdev_reread_part() function.
* Added a rwlock which is held as a writer while a disk is being
reopened. This is important to prevent errors from occurring
for any configuration related IOs which bypass the SCL_ZIO lock.
The zpool_reopen_007_pos.ksh test case was added to verify IO
error are never observed when reopening. This is not expected
to impact IO performance.
Additional fixes which aren't critical but were discovered and
resolved in the course of developing this functionality.
* Added PHYS_PATH="/dev/zvol/dataset" to the vdev configuration for
ZFS volumes. This is as good as a unique physical path, while the
volumes are not used in the test cases anymore for other reasons
this improvement was included.

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

a common.sh with in-tree path information from the common.sh.in
template. This file and sourced by the test scripts and used
for in-tree testing, it is not included in the packages. When
building packages 'make install' uses the same template to
create a new common.sh which is appropriate for the packaging.
* Removed unused functions/variables from scripts/common.sh.in.
Only minimal path information and configuration environment
variables remain.
* Removed unused scripts from scripts/ directory.
* Remaining shell scripts in the scripts directory updated to
cleanly pass shellcheck and added to checked scripts.
* Renamed tests/test-runner/cmd/ to tests/test-runner/bin/ to
match install location name.
* Removed last traces of the --enable-debug-dmu-tx configure
options which was retired some time ago.

Porting notes:
- The 6643 changes were dropped a different version of this script

test-runner should be creating the current symlink in the
directory above the output directory. In a previous commit,
the current symlink was placed in the current working
directory, which could be inaccessible. It is more likely
that the output directory is always accessible.
This is needed because without this there's no deterministic
way to get the path to ZFS Test Suite results until after the
test suite has started. This makes it difficult for buildbot to
follow the log file.

ZFS Test Suite Performance Regression Tests
This was pulled into OpenZFS via the compressed arc featureand was
separated out in zfsonlinux as a separate pull request from PR-4768.
It originally came in as QA-4903 in Delphix-OS from John Kennedy.
Expected Usage:
$ DISKS="sdb sdc sdd" zfs-tests.sh -r perf-regression.run
Porting Notes:
1. Added assertions in the setup script to make sure required tools
(fio, mpstat, ...) are present.
2. For the config.json generation in perf.shlib used arcstats and
other binaries instead of dtrace to query the values.
3. For the perf data collection:
- use "zpool iostat -lpvyL" instead of the io.d dtrace script
(currently not collecting zfs_read/write latency stats)
- mpstat and iostat take different arguments
- prefetch_io.sh is a placeholder that uses arcstats instead of
dtrace
4. Build machines require fio, mdadm and sysstat pakage (YMMV).
Future Work:
- Need a way to measure zfs_read and zfs_write latencies per pool.
- Need tools to takes two sets of output and display/graph the
differences
- Bring over additional regression tests from Delphix
Add helpers which automatically retry the provided command when
the error message matches the provided keyword. This provides an
easy way to handle the asynchronous nature of some ZFS commands.
For example, the `zfs destroy` command may need to be retried in
the case where the block device is unexpected busy. This can be
accomplished as follows:
log_must_busy $ZFS destroy ...

Issue #5002
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 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:
