The EXTRA_DIST variable is ignored when used in the FALSE conditional
of a Makefile.am. This results in the `make dist` target omitting
these files from the generated tarball unless CONFIG_USER is defined.
This issue can be avoided by switching to use the dist_noinst_DATA
variable which is handled as expected by autoconf.
This change also adds support for --with-config=dist as an alias
for --with-config=srpm and updates the GitHub workflows to use it.

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.

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.

This patch adds a new top-level vdev type called dRAID, which stands
for Distributed parity RAID. This pool configuration allows all dRAID
vdevs to participate when rebuilding to a distributed hot spare device.
This can substantially reduce the total time required to restore full
parity to pool with a failed device.
A dRAID pool can be created using the new top-level `draid` type.
Like `raidz`, the desired redundancy is specified after the type:
`draid[1,2,3]`. No additional information is required to create the
pool and reasonable default values will be chosen based on the number
of child vdevs in the dRAID vdev.
zpool create <pool> draid[1,2,3] <vdevs...>
Unlike raidz, additional optional dRAID configuration values can be
provided as part of the draid type as colon separated values. This
allows administrators to fully specify a layout for either performance
or capacity reasons. The supported options include:
zpool create <pool> \
draid[<parity>][:<data>d][:<children>c][:<spares>s] \
<vdevs...>
- draid[parity] - Parity level (default 1)
- draid[:<data>d] - Data devices per group (default 8)
- draid[:<children>c] - Expected number of child vdevs
- draid[:<spares>s] - Distributed hot spares (default 0)

with two distributed spares using special allocation classes.

When adding test coverage for the new dRAID vdev type the following
options were added to the ztest command. These options are leverages
by zloop.sh to test a wide range of dRAID configurations.
-K draid|raidz|random - kind of RAID to test
-D <value> - dRAID data drives per group
-S <value> - dRAID distributed hot spares
-R <value> - RAID parity (raidz or dRAID)
The zpool_create, zpool_import, redundancy, replacement and fault
test groups have all been updated provide test coverage for the
dRAID feature.

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.

drop the dist-hook for zfs_gitrev.h. There is no need to distribute this

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

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.

Provide infrastructure to auto-configure to enum and API changes in the

arc_free_memory has been broken since an API change in Linux v3.14:

2016-07-28 v4.8 75ef7184 mm, vmstat: add infrastructure for per-node
vmstats
These commits moved some of global_page_state() into
global_node_page_state(). The API change was particularly egregious as,
instead of breaking the old code, it silently did the wrong thing and we
continued using global_page_state() where we should have been using
global_node_page_state(), thus indexing into the wrong array via
NR_SLAB_RECLAIMABLE et al.

2017-09-06 v4.14 c41f012a mm: rename global_page_state to

* 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:

The ziltest.sh script is a test case designed to verify the correct
functioning of the ZIL. It's being added to the scripts directory
so it can be easily added to the automated regression testing.
The general idea is to build up an intent log from a bunch of
diverse user commands without actually committing them to the file
system. Then copy the file system, replay the intent log and
compare the file system and the copy.

New versions of dkms clean up the build directory after installing.
It appears that this was always intended, but had rm -rf "/path/to/build/*"
(note the quotes), which prevented it from working.
Also, the build step is already installing stuff into the directory where
these files go, so installing our stuff there as part of build rather than
install makes sense.

Verify that an assortment of known good reference pools can be imported
using different versions of the ZoL code.
By default references pools for the major ZFS implementation will be
checked against the most recent ZoL tags and the master development branch.
Alternate tags or branches may be verified with the '-s <src-tag> option.
Passing the keyword "installed" will instruct the script to test whatever
version is installed.
Preferentially a reference pool is used for all tests. However, if one
does not exist and the pool-tag matches one of the src-tags then a new
reference pool will be created using binaries from that source build.
This is particularly useful when you need to test your changes before
opening a pull request.
New reference pools may be added by placing a bzip2 compressed tarball
of the pool in the scripts/zpool-example directory and then passing
the -p <pool-tag> option. To increase the test coverage reference pools
should be collected for all the major ZFS implementations. Having these
pools easily available is also helpful to the developers.
Care should be taken to run these tests with a kernel supported by all
the listed tags. Otherwise build failure will cause false positives.
EXAMPLES:
The following example will verify the zfs-0.6.2 tag, the master branch,
and the installed zfs version can correctly import the listed pools.
Note there is no reference pool available for master and installed but
because binaries are available one is automatically constructed. The
working directory is also preserved between runs (-k) preventing the
need to rebuild from source for multiple runs.
zimport.sh -k -f /var/tmp/zimport \
-s "zfs-0.6.1 zfs-0.6.2 master installed" \
-p "all master installed"

Issue #2094
Cstyle is the C source style checker used by Illumos. Since the
original ZFS source was written using these style guidelines they
must also be followed by ZoL for consistency.
The checker has been added to the scripts directory and may be
run on a per file basis. New patches should be careful to avoid
introducing new style warnings.
Additionally, the 'checkstyle' target has been added to the top
level Makefile and can be used to check the entire source tree.
While Zol has historically attempted to follow the SunOS style
guide the lack of a rigorous style checker has allowed various
warning to be introduced. Currently there are 2211 reported
style violations and we want to gradually eliminate these from
the tree.
Note the cstyle.1 man page is provided under man/man1/cstyle.1
but since it is a developer utility it is not installed along
with the other man pages.

Added a simple sed script to do a search and replace on the Illumos
ZFS file names and replace them with the ZFS on Linux equivalent.
Example usage:
# Replace Illumos paths with Linux paths
$ ./scripts/zfs2zol-patch.sed arc.c.patch > arc.c.patch.linux
# Ensure the script worked as expected
$ diff arc.c.patch arc.c.patch.linux
# Apply the patch using Linux paths

Refresh the existing RPM packaging to conform to the 'Fedora
Packaging Guidelines'. This includes adopting the kmods2
packaging standard which is used fod kmods distributed by
rpmfusion for Fedora/RHEL.
http://fedoraproject.org/wiki/Packaging:Guidelineshttp://rpmfusion.org/Packaging/KernelModules/Kmods2
While the spec files have been entirely rewritten from a
user perspective the only major changes are:
* The Fedora packages now have a build dependency on the
rpmfusion repositories. The generic kmod packages also
have a new dependency on kmodtool-1.22 but it is bundled
with the source rpm so no additional packages are needed.
* The kernel binary module packages have been renamed from
zfs-modules-* to kmod-zfs-* as specificed by kmods2.
* The is now a common kmod-zfs-devel-* package in addition
to the per-kernel devel packages. The common package
contains the development headers while the per-kernel
package contains kernel specific build products.

In the interest of maintaining only one udev helper to give vdevs
user friendly names, the zpool_id and zpool_layout infrastructure
is being retired. They are superseded by vdev_id which incorporates
all the previous functionality.

file, vdev_id.conf(5), can be found in their respective man pages.
Several useful example files are installed under /etc/zfs/.

The idea behind the '-c' flag is to cleanup everything from a
previous test run which might cause the test script to fail.
This should also include removing the previously loaded module.
This makes it a little easier to run 'zconfig.sh -c', however
remember this is a test script and it will take all of your
other zpools offline for the purposes of the test. This notion
has also been extended to the default 'make check' behavior.
Eleven new zpool configurations were added to allow testing of various
failure cases. The first 5 zpool configurations leverage the 'faulty'
md device type which allow us to simuluate IO errors at the block layer.
The last 6 zpool configurations leverage the scsi_debug module provided
by modern kernels. This device allows you to create virtual scsi
devices which are backed by a ram disk. With this setup we can verify
the full IO stack by injecting faults at the lowest layer. Both methods
of fault injection are important to verifying the IO stack.
The zfs code itself also provides a mechanism for error injection
via the zinject command line tool. While we should also take advantage
of this appraoch to validate the code it does not address any of the
Linux integration issues which are the most concerning. For the
moment we're trusting that the upstream Solaris guys are running
zinject and would have caught internal zfs logic errors.
Currently, there are 6 r/w test cases layered on top of the 'faulty'
md devices. They include 3 writes tests for soft/transient errors,
hard/permenant errors, and all writes error to the device. There
are 3 matching read tests for soft/transient errors, hard/permenant
errors, and fixable read error with a write. Although for this last
case zfs doesn't do anything special.
The seventh test case verifies zfs detects and corrects checksum
errors. In this case one of the drives is extensively damaged and
by dd'ing over large sections of it. We then ensure zfs logs the
issue and correctly rebuilds the damage.
The next test cases use the scsi_debug configuration to injects error
at the bottom of the scsi stack. This ensures we find any flaws in the
scsi midlayer or our usage of it. Plus it stresses the device specific
retry, timeout, and error handling outside of zfs's control.
The eighth test case is to verify that the system correctly handles an
intermittent device timeout. Here the scsi_debug device drops 1 in N
requests resulting in a retry either at the block level. The ZFS code
does specify the FAILFAST option but it turns out that for this case
the Linux IO stack with still retry the command. The FAILFAST logic
located in scsi_noretry_cmd() does no seem to apply to the simply
timeout case. It appears to be more targeted to specific device or
transport errors from the lower layers.
The ninth test case handles a persistent failure in which the device
is removed from the system by Linux. The test verifies that the failure
is detected, the device is made unavailable, and then can be successfully
re-add when brought back online. Additionally, it ensures that errors
and events are logged to the correct places and the no data corruption
has occured due to the failure.
