Currently, wait_scrubbed() is the only function of its kind that
accepts a timeout, which is 10s by default. This timeout is pretty
short for a scrub and causes test failures if we run too long. This
patch removes the timeout, instead leaning on the global test suite
timeout to ensure the tests keep moving.

* Detect IO errors during device removal
While device removal cannot verify the checksums of individual
blocks during device removal, it can reasonably detect hard IO
errors from the leaf vdevs. Failure to perform this error
checking can result in device removal completing successfully,
but moving no data which will permanently corrupt the pool.
Situation 1: faulted/degraded vdevs
In the configuration shown below, the removal of mirror-0 will
permanently corrupt the pool. Device removal will preferentially
copy data from 'vdev1 -> vdev3' and from 'vdev2 -> vdev4'. Which
in this case will result in nothing being copied since one vdev
in each of those groups in unavailable. However, device removal
will complete successfully since all IO errors are ignored.
tank DEGRADED 0 0 0
mirror-0 DEGRADED 0 0 0
/var/tmp/vdev1 FAULTED 0 0 0 external fault
/var/tmp/vdev2 ONLINE 0 0 0
mirror-1 DEGRADED 0 0 0
/var/tmp/vdev3 ONLINE 0 0 0
/var/tmp/vdev4 FAULTED 0 0 0 external fault
This issue is resolved by updating the source child selection
logic to exclude unreadable leaf vdevs. Additionally, unwritable
destination child vdevs which can never succeed are skipped to
prevent generating a large number of write IO errors.
Situation 2: individual hard IO errors
During removal if an unexpected hard IO error is encountered when
either reading or writing the child vdev the entire removal
operation is cancelled. While it may be possible to reconstruct
the data after removal that cannot be guaranteed. The only
strictly safe thing to do is to cancel the removal.
As a future improvement we may want to instead suspend the removal
process and allow the damaged region to be retried. But that work
is left for another time, hard IO errors during the removal process
are expected to be exceptionally rare.

Issue #6900Closes#8161
Currently, several tests in the ZFS Test Suite that attempt to
test scrub and resilver behavior occasionally fail. A big reason
for this is that these tests use a combination of zinject and
zfs_scan_vdev_limit to attempt to slow these operations enough
to verify their test commands. This method works most of the time,
but provides no guarantees and leads to flaky behavior. This patch
adds a new tunable, zfs_scan_suspend_progress, that ensures that
scans make no progress, guaranteeing that tests can be run without
racing.
This patch also changes zfs_remove_max_bytes_pause to match this
new tunable. This provides some consistency between these two
similar tunables and ensures that the tunable will not misbehave
on 32-bit systems.

Currently, if a resilver is triggered for any reason while an
existing one is running, zfs will immediately restart the existing
resilver from the beginning to include the new drive. This causes
problems for system administrators when a drive fails while another
is already resilvering. In this case, the optimal thing to do to
reduce risk of data loss is to wait for the current resilver to end
before immediately replacing the second failed drive, which allows
the system to operate with two incomplete drives for the minimum
amount of time.
This patch introduces the resilver_defer feature that essentially
does this for the admin without forcing them to wait and monitor
the resilver manually. The change requires an on-disk feature
since we must mark drives that are part of a deferred resilver in
the vdev config to ensure that we do not assume they are done
resilvering when an existing resilver completes.

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.

There are some issues with the way the seq_file interface is implemented
for kstats backed by linked lists (zfs_dbgmsgs and certain per-pool
debugging info):
* We don't account for the fact that seq_file sometimes visits a node
multiple times, which results in missing messages when read through
procfs.
* We don't keep separate state for each reader of a file, so concurrent
readers will receive incorrect results.
* We don't account for the fact that entries may have been removed from
the list between read syscalls, so reading from these files in procfs
can cause the system to crash.
This change fixes these issues and adds procfs_list, a wrapper around a
linked list which abstracts away the details of implementing the
seq_file interface for a list and exposing the contents of the list
through procfs.

When no permission set is defined for a dataset the create time
permissions are incorrectly shown as if they were a permission set.
This change simply correct how allow permissions are displayed.
This commit also fixes a small manpage formatting issue and adds the
"zfs_allow_003_pos" test case to the ZFS Test Suite.

Allocation Classes add the ability to have allocation classes in a
pool that are dedicated to serving specific block categories, such
as DDT data, metadata, and small file blocks. A pool can opt-in to
this feature by adding a 'special' or 'dedup' top-level VDEV.

We want newer versions of libzfs_core to run against an existing
zfs kernel module (i.e. a deferred reboot or module reload after
an update).
Programmatically document, via a zfs_ioc_key_t, the valid arguments
for the ioc commands that rely on nvpair input arguments (i.e. non
legacy commands from libzfs_core). Automatically verify the expected
pairs before dispatching a command.
This initial phase focuses on the non-legacy ioctls. A follow-on
change can address the legacy ioctl input from the zfs_cmd_t.
The zfs_ioc_key_t for zfs_keys_channel_program looks like:
static const zfs_ioc_key_t zfs_keys_channel_program[] = {
{"program", DATA_TYPE_STRING, 0},
{"arg", DATA_TYPE_UNKNOWN, 0},
{"sync", DATA_TYPE_BOOLEAN_VALUE, ZK_OPTIONAL},
{"instrlimit", DATA_TYPE_UINT64, ZK_OPTIONAL},
{"memlimit", DATA_TYPE_UINT64, ZK_OPTIONAL},
};
Introduce four input errors to identify specific input failures
(in addition to generic argument value errors like EINVAL, ERANGE,
EBADF, and E2BIG).
ZFS_ERR_IOC_CMD_UNAVAIL the ioctl number is not supported by kernel
ZFS_ERR_IOC_ARG_UNAVAIL an input argument is not supported by kernel
ZFS_ERR_IOC_ARG_REQUIRED a required input argument is missing
ZFS_ERR_IOC_ARG_BADTYPE an input argument has an invalid type

This extends our sysfs '/sys/module/zfs' entry to include feature
and property attributes. The primary consumer of this information
is user processes, like the zfs CLI, that need to know what the
current loaded ZFS module supports. The libzfs binary will consult
this information when instantiating the zfs and zpool property
tables and the pool features table.
This introduces 4 kernel objects (dirs) into '/sys/module/zfs'
with corresponding attributes (files):
features.runtime
features.pool
properties.dataset
properties.pool

It's possible for an unrelated process, like blkid, to have the
volume open when 'zfs destroy' is run. Switch the cleanup functions
to the destroy_dataset() helper which handles this case by retrying
the destroy when the dataset is busy. This was done not only for
volumes but also for file systems for consistency.
