Historically a dynamic misc minor number was registered for the
/dev/zfs device in order to prevent minor number collisions. This
was fine but it prevented us from being able to use the kernel
module auto-loaded which requires a known reserved value.
Resolve this issue by adding a configure test to find an available
misc minor number which can then be used in MODULE_ALIAS_MISCDEV at
build time. By adding this alias the zfs kmod is added to the list
of known static-nodes and the systemd-tmpfiles-setup-dev service
will create a /dev/zfs character device at boot time.
This in turn allows us to update the 90-zfs.rules file to make it
aware this is a static node. The upshot of this is that whenever
a process (zpool, zfs, zed) opens the /dev/zfs the kmods will be
automatic loaded. This even works for unprivileged users so there
is no longer a need to manually load the modules at boot time.
As an additional bonus the zed now no longer needs to start after
the zfs-import.service since it will trigger the module load.
In the unlikely event the minor number we selected conflicts with
another out of tree unregistered minor number the code falls back
to dynamically allocating it. In this case the modules again
must be manually loaded.
Note that due to the change in the method of registering the minor
number the zimport.sh test case may incorrectly fail when the
static node for the installed packages is created instead of the
dynamic one. This issue will only transiently impact zimport.sh
for this single commit when we transition and are mixing and
matching methods.

This reverts commit 2a16d4cfaf.
The commit was causing a "attempt to access beyond the end

list.zfsonlinux.org/pipermail/zfs-discuss/2018-September/032217.html
This is a port of 047116ac - Raw sends must be able to decrease nlevels,
to the zfs-0.7-stable branch. It includes the various fixes to the
problem of receiving incremental streams which include reallocated dnodes
in which the number of dnode slots has changed but excludes the parts
which are related to raw streams.
From 047116ac:
Currently, when a raw zfs send file includes a
DRR_OBJECT record that would decrease the number of
levels of an existing object, the object is reallocated
with dmu_object_reclaim() which creates the new dnode
using the old object's nlevels. For non-raw sends this
doesn't really matter, but raw sends require that
nlevels on the receive side match that of the send
side so that the checksum-of-MAC tree can be properly
maintained. This patch corrects the issue by freeing
the object completely before allocating it again in
this case.
This patch also corrects several issues with
dnode_hold_impl() and related functions that prevented
dnodes (particularly multi-slot dnodes) from being
reallocated properly due to the fact that existing
dnodes were not being fully cleaned up when they
were freed.
This patch adds a test to make sure that zfs recv
functions properly with incremental streams containing
dnodes of different sizes.
This also includes a one-liner fix from loli10K to fix a test failure:

follow this one.
When receiving an incremental send stream with intermediary snapshots
zfs_receive_one() does not correctly identify the top-level dataset:
consequently we restore said snapshots as if they were children
datasets in the hierarchy, forcing inheritance of any property received
with 'zfs send -o' and effectively removing any locally set value.
The test case did not correctly verify this situation because it uses
adjacent snapshots, basically testing 'zfs send -i' instead of
'zfs send -I': this commit adds an additional intermediary snapshot to
the test script.

Because resuming from a token requires "guid" -> "snapshot" mapping
we have to walk the whole dataset hierarchy to find the right snapshot
to send; when both source and destination exists, for an incremental

to send from: this results in attempting to send
"destination@snap1 -> source@snap2"
instead of

Fix this by adjusting the logic behind dataset traversal in

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.

The existing kernel-side code only provides a method to rollback to a

is actually done. That could be unsafe or confusing in environments
where concurrent DSL changes are possible as the resulting state could
correspond to a newer or older snapshot than the originally requested
one.
This change allows to amend that method such that the rollback is
performed only when the latest snapshot has a specific name. That is,
if a new snapshot is concurrently created or the target snapshot is
destroyed, then no rollback is done and EXDEV error is returned.
New libzfs_core function lzc_rollback_to() is provided for the new
functionality. libzfs is changed to use lzc_rollback_to() to implement
zfs rollback command.
Perhaps we should return different errors to distinguish the case where
the desired snapshot exists but it's not the latest snapshot and the

Document the existence of `createtxg` and `guid` native properties
in man pages and zfs command output.
One of the great features of ZFS is incremental replication of
snapshots, possibly between pools on different machines.
Shell scripts are commonly used to auomate this procedure. They have to
find the most recent common snapshot between both sides and then
perform incremental send & recv.
Currently, scripts rely on the sorting order of `zfs list`, which
defaults to `createtxg`, and the assumption that snapshot names on
either side do not change.
By making `createtxg` and `guid` part of the public ZFS interface,
scripts are enabled to use
a) `createtxg` to determine the logical & temporal order of snapshots
(the creation property is not an equivalent substitute since
multiple snapshots may be created within one second)
b) `guid` to uniquely identify a snapshot, independent of its current
display name
This has the potential of making scripts safer and correct.

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.

musl's sys/errno.h is literally:
/#warning redirecting incorrect #include <sys/errno.h> to <errno.h>
/#include <errno.h>
It does the same for sys/{poll,signal}.h. This is rather noisy when
building ZoL against musl. musl is also correct in pointing out that the
correct headers are outside of sys/ according to the single unix
specification:
http://pubs.opengroup.org/onlinepubs/7908799/xsh/errno.h.htmlhttp://pubs.opengroup.org/onlinepubs/7908799/xsh/poll.h.htmlhttp://pubs.opengroup.org/onlinepubs/7908799/xsh/signal.h.html
Lets implement our own sys/* versions of these headers to redirect to
the proper userland ones when building in userspace. That will silence
the warning.
There are also some instances where we include incorrectly from sys/ or
from outside of sys/ in userspace only code. In these instances, lets
just fix the includes directly.

Porting Notes:
- Updated 'zpool labelclear' and 'zdb -l' such that they attempt
to find a vdev given solely its short name. This behavior is
consistent with the upstream OpenZFS code and the test cases
depend on it. The actual implementation differs slightly due
to device naming conventions on Linux.
- auto_online_001_pos, auto_replace_001_pos and add-o_ashift
test cases updated to expect failure when no label exists.
- read_efi_label() and zpool_label_disk_check() are read-only
operations and should use O_RDONLY at open time to enforce this.
- zpool_label_disk() and zpool_relabel_disk() write the partition
information using O_DIRECT an fsync() and page cache invalidation
to ensure a consistent view of the device.
- dump_label() in zdb should invalidate the page cache in order
to get the authoritative label from disk.

recv_incremental_replication() takes care of things like removing
datasets that have been removed on the sending side, detecting renamed
datasets, ensuring that all datasets in the affected hierarchy have the
same properties as their counterparts on the sending side.
All of the above are not necessary if we are receiving a stream for a
single dataset that has been generated with zfs send -p, that is, a
stream that includes properties. zfs_receive_one() already takes care
of applying the properties to the received datasets.

When a pool is suspended it's impossible to read the list
of damaged files from disk. This would result in a generic
misleading "insufficient permissions" error message.
Update zpool_get_errlog() to use the standard zpool error
logging functions to generate a useful error message. In
this case:
errors: List of errors unavailable: pool I/O is currently suspended
This patch does not address the related issue of potentially
not being able to resume a suspend pool when the underlying
device names have changed.
Additionally, remove the error handling from zfs_alloc()
in zpool_get_errlog() for readability since this function
can never fail.

This clears vdev_enc_sysfs_path from the label if the VDEV's
/sys/class/block/<dev>/device/enclosure_device path isn't present.
This is important in the case where a disk that is labeled with
vdev_enc_sysfs_path is pulled out and put into another enclosure.
In that case, it's possible that the old sysfs path would be used to
turn on the fault LED for the disk's old slot postion, assuming the
new slot didn't have a LED sysfs entry.
