for and if available used. Otherwise, configure will fall back to using
the xdr implementation provided by libc if available. The options
--with-tirpc/--without-tirpc can be used to disable this checking.
In addition, the xdr_control() function has been simplied to only

When importing a pool using the blkid cache only the device

This results in 'zpool import' always using the sdX names

To fix the issue the blkid import path has been updated to

When ZFS partitions a block device it must wait for udev to create
both a device node and all the device symlinks. This process takes
a variable length of time and depends on factors such how many links
must be created, the complexity of the rules, etc. Complicating
the situation further it is not uncommon for udev to create and
then remove a link multiple times while processing the udev rules.
Given the above, the existing scheme of waiting for an expected
partition to appear by name isn't 100% reliable. At this point
udev may still remove and recreate think link resulting in the
kernel modules being unable to open the device.
In order to address this the zpool_label_disk_wait() function
has been updated to use libudev. Until the registered system
device acknowledges that it in fully initialized the function
will wait. Once fully initialized all device links are checked
and allowed to settle for 50ms. This makes it far more likely
that all the device nodes will exist when the kernel modules
need to open them.
For systems without libudev an alternate zpool_label_disk_wait()
was updated to include a settle time. In addition, the kernel
modules were updated to include retry logic for this ENOENT case.
Due to the improved checks in the utilities it is unlikely this
logic will be invoked. However, if the rare event it is needed
it will prevent a failure.

When partitioning a device a name may be specified for each partition.
Internally zfs doesn't use this partition name for anything so it
has always just been set to "zfs".
However this isn't optimal because udev will create symlinks using
this name in /dev/disk/by-partlabel/. If the name isn't unique
then all the links cannot be created.
Therefore a random 64-bit value has been added to the partition
label, i.e "zfs-1234567890abcdef". Additional information could
be encoded here but since partitions may be reused that might
result in confusion and it was decided against.

Current zpool import code skips directory entries which have prefixes
similar to some system files on linux such as "fd", "core" etc. However,
this means one cannot have one's zpools hosted inside files which are named
e.g. core-1 or lp. Furthermore, apart from the string checks there is already
which makes the zpool_open_func work only with regular files and block devices.
To fix this problem remove most of the checks since they are redundant but
leave the checks for the 'hpet' and 'watchdog' names. Furthermore, change
the checks to strcmp which albeit less safe than strncmp allows to have
devices whose names are prefixed by 'hpet' or 'watchdog'.

I noticed during code review of zfsonlinux/zfs#4385 that the author of a
commit had peppered the various Makefile.am files with `$(TIRPC_LIBS)`
when putting it into `lib/libspl/Makefile.am` should have sufficed. Upon
further examination, it seems that he had copied what we do with
`$(ZLIB)`. We also have a bit of that with `-ldl` too. Unfortunately,
what we do is wrong, so lets fix it to set a good example for future
contributors.
In addition, we have multiple `-lz` and `-luuid` passed to the compiler
because each `AC_CHECK_LIB` adds it to `$LIBS`. That is somewhat
annoying to see, so we switch to `AC_SEARCH_LIBS` to avoid it. This is
consistent with the recommendation to use `AC_SEARCH_LIBS` over
`AC_CHECK_LIB` by autotools upstream:
https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/Libraries.html
In an ideal world, this would translate into improvements in ELF's
`DT_NEEDED` entries, but that is not the case because of a couple of
bugs in libtool.
The first bug causes libtool to overlink by using static link
dependencies for dynamic linking:
https://wiki.mageia.org/en/Overlinking_issues_in_packaging#libtool_issues
The workaround for this should be to pass `-Wl,--as-needed` in
`LDFLAGS`. That leads us to the second bug, where libtool passes
`LDFLAGS` after the libraries are specified and `ld` will only honor
`--as-needed` on libraries specified before it:
https://sigquit.wordpress.com/2011/02/16/why-asneeded-doesnt-work-as-expected-for-your-libraries-on-your-autotools-project/
There are a few possible workarounds for the second bug. One is to
either patch the compiler spec file to specify `-Wl,--as-needed` or pass
`-Wl,--as-needed` via `CC` like `CC='gcc -Wl,--as-needed'` so that it is
specified early. Another is to patch ltmain.sh like Gentoo does:
https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/ELT-patches/as-needed
Without one of those workarounds, this cleanup provides no benefit in
terms of `DT_NEEDED` entry generation. It should still be an improvement
because it nicely simplifies the code while encouraging good habits when
patching autotools scripts.

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:

This way if one pool is suspended it will not impact another.

Historically libblkid support was detected as part of configure
and optionally enabled. This was done because at the time support
for detecting ZFS pool vdevs had just be added to libblkid and
those updated packages were not yet part of many distributions.
This is no longer the case and any reasonably current distribution
will ship a version of libblkid which can detect ZFS pool vdevs.
This patch makes libblkid mandatory at build time and libblkid
the preferred method of scanning for ZFS pools. For distributions
which include a modern version of libblkid there is no change in
behavior. Explicitly scanning the default search paths is still
supported and can be enabled with the '-s' command line option.
Additionally making libblkid mandatory means that the 'zpool create'
command can reliably detect if a specified device has an existing
non-ZFS filesystem (ext4, xfs) and print a warning.

to perform the needed thread initialization.
- The check_one_slice, nozpool_all_slices, and check_slices

are get names. Since this is only an optimization this code

Porting notes:
- Internal zvol.c changes not applied due to implementation differences.
The external interface and behavior was already consistent with the
latest upstream code.
- Retired 2.6.28 HAVE_CHECK_DISK_SIZE_CHANGE configure check. All
supported kernels (2.6.32 and newer) provide this interface.
