receive: don't fail inheriting (-x) properties on wrong dataset type
Receiving datasets while blanket inheriting properties like zfs 
receive -x mountpoint can generally be desirable, e.g. to avoid 
unexpected mounts on backup hosts.

Currently this will fail to receive zvols due to the mountpoint 
property being applicable to filesystems only.  This limitation 
currently requires operators to special-case their minds and tools 
for zvols.

This change gets rid of this limitation for inherit (-x) by
Spiting up the dataset type handling: Warnings for inheriting (-x), 
errors for overriding (-o).

zed: protect against wait4()/fork() races to the launched process tree
As soon as wait4() returns, fork() can immediately return with the same
PID, and race to lock _launched_processes_lock, then try to add the new
(duplicate) PID to _launched_processes, which asserts

By locking before wait4(), we ensure, that, given that same
unfortunate scheduling, _launched_processes_lock cannot be locked by the
spawner before we pop the process in the reaper, and only afterward will
it be added

This moves where the reaper idles when there are children from the
wait4() to the pause(), locking for the duration of that single syscall
in both the no-children and running-children cases; the impact of this
is one to two syscalls (depending on _launched_processes_lock state)
per loop

libspl: implement atomics in terms of atomics
This replaces the generic libspl atomic.c atomics implementation
with one based on builtin gcc atomics.  This functionality was added
as an experimental feature in gcc 4.4.  Today even CentOS 7 ships
with gcc 4.8 as the default compiler we can make this the default.

Furthermore, the builtin atomics are as good or better than our
hand-rolled implementation so it's reasonable to drop that custom code.

ZTS: Improve redundancy test scripts
- Add additional logging to provide more information about why the
  test failed.  This including logging more of the individual commands
  and the contents and differences of the record files on failure.

- Updated get_vdevs() to properly exclude all top-level vdevs
  including raidz3 and draid[1-3].

- Replaced gnudd with dd.  This is the only remaining place in the
  test suite gnudd is used and it shouldn't be needed.

- The refill_test_env function expects the pool as the first argument
  but never sets the pool variable.

- Only fill the test pools to 50% of capacity instead of 75% to help
  speed up the tests.

- Fix replace_missing_devs() calculation, MINDEVSIZE should be
  MINVDEVSIZE.

- Fix damage_devs() so it overwrites almost all of the device so
  we're guaranteed to damage filesystem blocks.

- redundancy_stripe.ksh should not use log_mustnot to check if the
  pool is healthy since the return value may be misinterpreted.
  Just perform a normal conditional check and log the failure.

наб a31ac10185 libzfs: refresh property cache after inheriting userprop
This matches what happens when inheriting a system property

Consider the following program:
	int main() {
		void *zhp = libzfs_init();
		void *dataset = zfs_open(zhp, "zest/__test", 1);

		printf("before:");
		dump_nvlist(zfs_get_user_props(dataset), 2);
		printf("\n");

		zfs_prop_inherit(dataset, "xyz.nabijaczleweli:test", 0);
		printf("after:");
		dump_nvlist(zfs_get_user_props(dataset), 2);
		printf("\n");

		zfs_refresh_properties(dataset);
		printf("refreshed:");
		dump_nvlist(zfs_get_user_props(dataset), 2);
		printf("\n");
	}

And the output before:
	# zfs set xyz.nabijaczleweli:test=hehe zest/__test
	# ./a.out
	before:  xyz.nabijaczleweli:test:
	      value: 'hehe'

32927393dc1ccd60fb2bdc05b9e8e88753761469 ("sysctl: pass kernel pointers

proc_dostring() strips only the final new-line,

ZFS traverse_visitbp optimization to limit prefetch
Traversal code, traverse_visitbp() does visit blocks recursively.
Indirect (Non L0) Block of size 128k could contain, 1024 block pointers
of 128 bytes. In case of full traverse OR incremental traverse, where
all blocks were modified, it could traverse large number of blocks
pointed by indirect. Traversal code does issue prefetch of blocks
traversed below indirect. This could result into large number of
async reads queued on vdev queue. So, account for prefetch issued for
blocks pointed by indirect and limit max prefetch in one go.

Module Param:
zfs_traverse_indirect_prefetch_limit: Limit of prefetch while traversing
an indirect block.

Local counters:
prefetched: Local counter to account for number prefetch done.
pidx: Index for which next prefetch to be issued.
ptidx: Index at which next prefetch to be triggered.

Keep "ptidx" somewhere in the middle of blocks prefetched, so that
blocks prefetch read gets the enough time window before their demand
read is issued.

this mirrors its behavior on Solaris. This way, long running kernel 
tasks can be stopped with the appropriate signals. Note that doing 
so with ctrl-z on the command line doesn't return control of the tty

наб 533527725b libzfs: get rid of libzfs_handle::libzfs_mnttab
All users did a freopen() on it. Even some non-users did!
This is point-less ‒ just open the mtab when needed

If I understand Solaris' getextmntent(3C) correctly, the non-user
freopen()s are very likely an odd, twisted vestigial tail of that ‒
but it's got a completely different calling convention and caching
semantics than any platform we support

libzfs: zfs_mount_at(): load key for encryption root if MS_CRYPT
zfs_crypto_load_key() only works on encryption roots,
and zfs mount -la would fail if it encounters a datasets that
is sorted before their encroots.

To trigger:
  truncate -s 40G /tmp/test
  dd if=/dev/urandom of=/tmp/k bs=128 count=1 status=none
  zpool create -O encryption=on -O keylocation=file:///tmp/k \
               -O keyformat=passphrase test /tmp/test
  zfs create -o mountpoint=/a test/a
  zfs create -o mountpoint=/b test/b
  zfs umount test
  zfs unload-key test
  zfs mount -la

The final mount errored out with:
  Key load error: Keys must be loaded for
    encryption root of 'test/a' (test).
  Key load error: Keys must be loaded for
    encryption root of 'test/b' (test).

And only /test was mounted

This technically breaks the libzfs API, but the previous behavior was
decidedly a bug.

cmd/zfs receive: allow dry-run (-n) to check property args
zfs recv -n does not report some errors it could.  The code to bail 
out of the receive if in dry-run mode came a little early, skipping 
validation of cmdprops (recv -x and -o) among others.  Move the
check down to enable these additional checks.

libuutil: purge unused functions
Remove vestigial uu_open_tmp().  The problems with this implementation
are many, but the primary one is the TMPPATHFMT macro, which is
unused, and always has been.

Searching around for any users leads only to earlier imports of the
same, identical file, i.a. into an apple repository (which does patch
gethrtime() into it and gives us a copyright date of 2007),
and a MidnightBSD one from 2008.

Searching illumos-gate, uu_open_tmp appears, in current HEAD, three
times: in the header, libuutil's mapfile ABI, and the implementation.

This slowly grows up to eight occurrences as one moves back to the root
"OpenSolaris Launch" commit: the header, implementation, twice in
libuutil's spec ABI, twice (with multilib and non-multilib paths) in
libuutil.so's i386 and SPARC binary db ABIs.

That's 2005, and this file was abandonware even then, it's dead code.

The situation is similar for the uu_dprintf() family of functions and
uu_dump().  Nothing in accessibly recorded history has ever used them.

Improvements to the 'compatibility' property
Several improvements to the operation of the 'compatibility' property:

1) Improved handling of unrecognized features:
Change the way unrecognized features in compatibility files are handled.

 * invalid features in files under /usr/share/zfs/compatibility.d
   only get a warning (as these may refer to future features not yet in
   the library),
 * invalid features in files under /etc/zfs/compatibility.d
   get an error (as these are presumed to refer to the current system).

2) Improved error reporting from zpool_load_compat.
Note: slight ABI change to zpool_load_compat for better error reporting.

3) compatibility=legacy inhibits all 'zpool upgrade' operations.

4) Detect when features are enabled outside current compatibility set
   * zpool set compatibility=foo <-- print a warning
   * zpool set feature@xxx=enabled <-- error
   * zpool status <-- indicate this state
