Ryan Moeller 85071b2ff5 FreeBSD: Initialize/destroy zp->z_lock
zp->z_lock is used in shared code for protecting projid and scantime.
We don't exercise these paths much if at all on FreeBSD, so have been
lucky enough not to have issues with the uninitialized locks so far.

Nathaniel Wesley Filardo 4ac37f8b2e vdev_mirror: don't scrub/resilver devices that can't be read
This ensures that we don't accumulate checksum errors against offline or
unavailable devices but, more importantly, means that we don't
needlessly create DTL entries for offline devices that are already
up-to-date.

Consider a 3-way mirror, with disk A always online (and so always with
an empty DTL) and B and C only occasionally online.  When A & B resilver
with C offline, B's DTL will effectively be appended to C's due to these
spurious ZIOs even as the resilver empties B's DTL:

  * These ZIOs land in vdev_mirror_scrub_done() and flag an error

  * That flagged error causes vdev_mirror_io_done() to see
    unexpected_errors, so it issues a ZIO_TYPE_WRITE repair ZIO, which
    inherits ZIO_FLAG_SCAN_THREAD because zio_vdev_child_io() includes
    that flag in ZIO_VDEV_CHILD_FLAGS.

  * That ZIO fails, too, and eventually zio_done() gets its hands on it
    and calls vdev_stat_update().

  * vdev_stat_update() sees the error and this zio...

    * is not speculative,
    * is not due to EIO (but rather ENXIO, since the device is closed)
    * has an ->io_vd != NULL (specifically, the offline leaf device)
    * is a write
    * is for a txg != 0 (but rather the read block's physical birth txg)
    * has ZIO_FLAG_SCAN_THREAD asserted

  * So: vdev_stat_update() calls vdev_dtl_dirty() on the offline vdev.

Then, when A & C resilver with B offline, that story gets replayed and
C's DTL will be appended to B's.

In fact, one does not need this permanently-broken-mirror scenario to
induce badness: breaking a mirror with no DTLs and then scrubbing will
create DTLs for all offline devices.  These DTLs will persist until the
entire mirror is reassembled for the duration of the *resilver*, which,
incidentally, will not consider the devices with good data to be sources
of good data in the case of a read failure.

Brian Behlendorf 6f2012c1dc zfs.spec.in: remove post ldconfig scriptlets
In Fedora 28 the packaging guidelines were changed such that ldconfig
should no longer be called in either the %post or %postun scriptlets.
Instead the new compatibility macros %ldconfig_post, %ldconfig_postun,
and %ldocnfig_scriptlets should be used.

Since we only currently support Fedora 31 and newer, we could drop
%post or %postun scriptlets entirely according to the guidelines.
However, since we also use the same spec file for CentOS / RHEL
it's convenient to call the macros which are available starting
with CentOS / RHEL 8.  For CentOS / RHEL 7 we must still call
ldconfig in the traditional way.

Prawn 6c1a7be11e 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).

наб 8fd65351a7 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

Brian Behlendorf 40abc63c40 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.

Jitendra Patidar 4c925936e3 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.

Paul Dagnelie d682e20ba4 Add SIGSTOP and SIGTSTP handling to issig
This change adds SIGSTOP and SIGTSTP handling to the issig function; 
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 
to the shell, because tty handling is done separately from stopping 
the process. That can be future work, if people feel that it is a 
necessary addition.

Brian Behlendorf 9c470dc6c0 Fix 'make checkbashisms` warnings
The awk command used by the checkbashisms target incorrectly
adds the escape character before the ! and # characters.  This
results in the following warnings because these characters do not
need to be escaped.

    awk: cmd. line:1: warning: regexp escape sequence
        `\!' is not a known regexp operator
    awk: cmd. line:1: warning: regexp escape sequence
        `\#' is not a known regexp operator

Remove the unneeded escape character before ! and #.

наб ecd6ad66b0 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.
