When performing concurrent object allocations using the new
multi-threaded allocator and large dnodes it's possible to
allocate overlapping large dnodes.
This case should have been handled by detecting an error
returned by dnode_hold_impl(). But that logic only checked
the returned dnp was not-NULL, and the dnp variable was not
reset to NULL when retrying. Resolve this issue by properly
checking the return value of dnode_hold_impl().
Additionally, it was possible that dnode_hold_impl() would
misreport a dnode as free when it was in fact in use. This
could occurs for two reasons:
* The per-slot zrl_lock must be held over the entire critical
section which includes the alloc/free until the new dnode
is assigned to children_dnodes. Additionally, all of the
zrl_lock's in the range must be held to protect moving
dnodes.
* The dn->dn_ot_type cannot be solely relied upon to check
the type. When allocating a new dnode its type will be
DMU_OT_NONE after dnode_create(). Only latter when
dnode_allocate() is called will it transition to the new
type. This means there's a window when allocating where
it can mistaken for a free dnode.

Without this commit, the mmp thread does not wake up and detect the new
interval until after it has waited the old multihost interval time. A
user monitoring mmp writes via the provided kstat would be led to
believe that the changed setting did not work.

Turning the multihost property on requires that a hostid be set to allow
ZFS to determine when a foreign system is attemping to import a pool.
The error message instructing the user to set a hostid refers to
genhostid(1).
Genhostid(1) is not available on SUSE Linux. This commit adds a script
modeled after genhostid(1) for those users.
Zgenhostid checks for an /etc/hostid file; if it does not exist, it
creates one and stores a value. If the user has provided a hostid as an
argument, that value is used. Otherwise, a random hostid is generated
and stored.
This differs from the CENTOS 6/7 versions of genhostid, which overwrite
the /etc/hostid file even though their manpages state otherwise.
A man page for zgenhostid is added. The one for genhostid is in (1), but
I put zgenhostid in (8) because I believe it's more appropriate.
The mmp tests are modified to use zgenhostid to set the hostid instead
of using the spl_hostid module parameter. zgenhostid will not replace
an existing /etc/hostid file, so new mmp_clear_hostid calls are
required.

This patch adds a '-f' option to 'zpool offline' to fault a vdev
instead of bringing it offline. Unlike the OFFLINE state, the
FAULTED state will trigger the FMA code, allowing for things like
autoreplace and triggering the slot fault LED. The -f faults
persist across imports, unless they were set with the temporary
(-t) flag. Both persistent and temporary faults can be cleared
with zpool clear.

Enable additional test cases, in most cases this required a few
minor modifications to the test scripts. In a few cases a real
bug was uncovered and fixed. And in a handful of cases where pools
are layered on pools the test case will be skipped until this is
supported. Details below for each test case.
* zpool_add_004_pos - Skip test on Linux until adding zvols to pools
is fully supported and deadlock free.
* zpool_add_005_pos.ksh - Skip dumpadm portion of the test which isn't
relevant for Linux. The find_vfstab_dev, find_mnttab_dev, and
save_dump_dev functions were updated accordingly for Linux. Add
O_EXCL to the in-use check to prevent the -f (force) option from
working for mounted filesystems and improve the resulting error.
* zpool_add_006_pos - Update test case such that it doesn't depend
on nested pools. Switch to truncate from mkfile to reduce space
requirements and speed up the test case.
* zpool_clear_001_pos - Speed up test case by filling filesystem to
25% capacity.
* zpool_create_002_pos, zpool_create_004_pos - Use sparse files for
file vdevs in order to avoid increasing the partition size.
* zpool_create_006_pos - 6ba1ce9 allows raidz+mirror configs with
similar redundancy. Updating the valid_args and forced_args cases.
* zpool_create_008_pos - Disable overlapping partition portion.
* zpool_create_011_neg - Fix to correctly create the extra partition.
Modified zpool_vdev.c to use fstat64_blk() wrapper which includes
the st_size even for block devices.
* zpool_create_012_neg - Updated to properly find swap devices.
* zpool_create_014_neg, zpool_create_015_neg - Updated to use
swap_setup() and swap_cleanup() wrappers which do the right thing
on Linux and Illumos. Removed '-n' option which succeeds under
Linux due to differences in the in-use checks.
* zpool_create_016_pos.ksh - Skipped test case isn't useful.
* zpool_create_020_pos - Added missing / to cleanup() function.
Remove cache file prior to test to ensure a clean environment
and avoid false positives.
* zpool_destroy_001_pos - Removed test case which creates a pool on
a zvol. This is more likely to deadlock under Linux and has never
been completely supported on any platform.
* zpool_destroy_002_pos - 'zpool destroy -f' is unsupported on Linux.
Mount point must not be busy in order to unmount them.
* zfs_destroy_001_pos - Handle EBUSY error which can occur with
volumes when racing with udev.
* zpool_expand_001_pos, zpool_expand_003_neg - Skip test on Linux
until adding zvols to pools is fully supported and deadlock free.
The test could be modified to use loop-back devices but it would
be preferable to use the test case as is for improved coverage.
* zpool_export_004_pos - Updated test case to such that it doesn't
depend on nested pools. Normal file vdev under /var/tmp are fine.
* zpool_import_all_001_pos - Updated to skip partition 1, which is
known as slice 2, on Illumos. This prevents overwriting the
default TESTPOOL which was causing the failure.
* zpool_import_002_pos, zpool_import_012_pos - No changes needed.
* zpool_remove_003_pos - No changes needed
* zpool_upgrade_002_pos, zpool_upgrade_004_pos - Root cause addressed
by upstream OpenZFS commit 3b7f360.
* zpool_upgrade_007_pos - Disabled in test case due to known failure.
Opened issue https://github.com/zfsonlinux/zfs/issues/6112
* zvol_misc_002_pos - Updated to to use ext2.
* zvol_misc_001_neg, zvol_misc_003_neg, zvol_misc_004_pos,
zvol_misc_005_neg, zvol_misc_006_pos - Moved to skip list, these
test case could be updated to use Linux's crash dump facility.
* zvol_swap_* - Updated to use swap_setup/swap_cleanup helpers.
File creation switched from /tmp to /var/tmp. Enabled minimal
useful tests for Linux, skip test cases which aren't applicable.

This allows users to specify "-o property=value" to override and
"-x property" to exclude properties when receiving a zfs send stream.
Both native and user properties can be specified.
This is useful when using zfs send/receive for periodic
backup/replication because it lets users change properties such as
canmount, mountpoint, or compression without modifying the source.

The send-c_volume test case has been observed to occasionally
fail on 32-bit systems. Until this issue is fully understood
disable this test case.
The rsend_014_pos test case can occasionally fail due to an

Resolve the issue by retrying the export on EBUSY. Additionally,
remove the gratuitous use of eval.

This commit allow higher ashift values (up to 16) in 'zpool create'
The ashift value was previously limited to 13 (8K block) in b41c990
because the limited number of uberblocks we could fit in the
statically sized (128K) vdev label ring buffer could prevent the
ability the safely roll back a pool to recover it.
Since b02fe35 the largest uberblock size we support is 8K: this
allow us to store a minimum number of 16 uberblocks in the vdev
label, even with higher ashift values.
Additionally change 'ashift' pool property behaviour: if set it will
be used as the default hint value in subsequent vdev operations
('zpool add', 'attach' and 'replace'). A custom ashift value can still
be specified from the command line, if desired.
Finally, fix a bug in add-o_ashift.ksh caused by a missing variable.

When vdev_psize increases, the location of labels 2 and 3 changes
because their location is relative to the end of the device.
The configs for labels 2 and 3 are written during the next spa_sync()
because the vdev is added to the dirty config list. However, the
uberblock rings are not re-written in their new location, leaving the
device vulnerable to the beginning of the device being overwritten or
damaged.
This patch copies the uberblock ring from label 0 to labels 2 and 3,
in their new locations, at the next sync after vdev_psize increases.
Also, add a test zpool_expand_004_pos.ksh to confirm the uberblocks
are copied.

Porting Notes:
- Most of 7252 was already picked up during ABD work. This
commit represents the gap from the final commit to openzfs.
- Fixed split_large_blocks check in do_dump()
- An alternate version of the write_compressible() function was
implemented for Linux which does not depend on fio. The behavior
of fio differs significantly based on the exact version.
- mkholes was replaced with truncate for Linux.

OpenZFS-commit: https://github.com/openzfs/openzfs/commit/5602294Closes#6067
This patch updates the "zpool status/iostat -c" commands to only run
"pre-baked" scripts from the /etc/zfs/zpool.d directory (or wherever
you install to). The scripts can only be run from -c as an unprivileged
user (unless the ZPOOL_SCRIPTS_AS_ROOT environment var is
set by root). This was done to encourage scripts to be written is such
a way that normal users can use them, and to be cautious. If your
script needs to run a privileged command, consider adding the
appropriate line in /etc/sudoers. See zpool(8) for an example of how
to do this.
The patch also allows the scripts to output custom column names. If
the script outputs a line like:
name=value
then "name" is used for the column name, and "value" is its value.
Multiple columns can be specified by outputting multiple lines. Column
names and values can have spaces. If the value is empty, a dash (-) is
printed instead.
After all the "name=value" lines are read (if any), zpool will take the
next the next line of output (if any) and print it without a column
header. After that, no more lines will be processed. This can be
useful for printing errors.
Lastly, this patch also disables the -c option with the latency and
request size histograms, since it produced awkward output and made the
code harder to maintain.

The `dd` command as written will not create a hole in the file.
Additionally, the `stride` argument isn't understood by `dd` so
it's replaced with `seek` which isn't equivilant but will result in
a single whole which is sufficient for the test case. Finally,
`conv=notrunc` is added to avoid truncating the file.
