When debugging is enabled and a zfs_refcount_t contains multiple holders
using the same key, but different ref_counts, the wrong reference_t may
be transferred. Add a zfs_refcount_transfer_ownership_many() function,
like the existing zfs_refcount_*_many() functions, to match and transfer
the correct refcount_t;
This issue may occur when using encryption with refcount debugging
enabled. An arc_buf_hdr_t can have references for both the
hdr->b_l1hdr.b_pabd and hdr->b_crypt_hdr.b_rabd both of which use
the hdr as the reference holder. When unsharing the buffer the
p_abd should be transferred.
This issue does not impact production builds because refcount holders
are not tracked.

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.

We'd like to have tooling that verifies code style, while ignoring the

ignore the commit message errors, or to run `make cstyle shellcheck
flake8 mancheck testscheck`, and make sure that list stays updated.
Solution is to add a new make target, `codecheck` which does all the
code checks. `checkstyle` is now simply `codecheck` + `commitcheck`.

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.

Issue #6143Closes#7941
Since native ZFS encryption was merged, we have been fighting
against a series of bugs that come down to the same problem: Key
mappings (which must be present during all I/O operations) are
created and destroyed based on dataset ownership, but I/Os can
have traditionally been allowed to "leak" into the next txg after
the dataset is disowned.
In the past we have attempted to solve this problem by trying to
ensure that datasets are disowned ater all I/O is finished by
calling txg_wait_synced(), but we have repeatedly found edge cases
that need to be squashed and code paths that might incur a high
number of txg syncs. This patch attempts to resolve this issue
differently, by adding a reference to the key mapping for each txg
it is dirtied in. By doing so, we can remove many of the
unnecessary calls to txg_wait_synced() we have added in the past
and ensure we don't need to deal with this problem in the future.

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.

Bandwidth and iops are average per second while *_wait are averages
per request for latency or, for queue depths, an instantaneous
measurement at the end of an interval (according to man zpool).
When calculating the first two it makes sense to do
x/interval_duration (x being the increase in total bytes or number of
requests over the duration of the interval, interval_duration in
seconds) to 'scale' from amount/interval_duration to amount/second.
But applying the same math for the latter (*_wait latencies/queue) is
wrong as there is no interval_duration component in the values (these
are time/requests to get to average_time/request or already an
absulute number).
This bug leads to the only correct continuous *_wait figures for both
latencies and queue depths from 'zpool iostat -l/q' being with
duration=1 as then the wrong math cancels itself (x/1 is a nop).
This removes temporal scaling from latency and queue depth figures.

When handling a 32-bit statfs() system call the returned fields,
although 64-bit in the kernel, must be limited to 32-bits or an

This is less of an issue for block counts since the default
reported block size in 128KiB. But since it is possible to
set a smaller block size, these values will be scaled as
needed to fit in a 32-bit unsigned long.
Unlike most other filesystems the total possible file counts
are more likely to overflow because they are calculated based
on the available free space in the pool. In order to prevent
this the reported value must be capped at 2^32-1. This is
only for statfs(2) reporting, there are no changes to the

Closes#7869
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.

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.

As a regular kernel function, kern_path() returns errors as negative
errnos, such as -ELOOP. zfsctl_snapdir_vget() must convert these into
the positive errnos used throughout the ZFS code when it returns them
to other ZFS functions so that the ZFS code properly sees them as
errors.
