11541 allocation_classes feature must be enabled to add log device

illumos/illumos-gate@c1064fd7ce
c1064fd7ce

https://www.illumos.org/issues/11541
  After the allocation_classes feature was integrated, one can no longer add a
  log device to a pool unless that feature is enabled. There is an explicit check
  for this, but it is unnecessary in the case of log devices, so we should handle
  this better instead of forcing the feature to be enabled.

Author: Jerry Jelinek <jerry.jelinek@joyent.com>

FreeBSD notes.
I faithfully added the new -g, -L, -P flags, but only -g does something:
vdev GUIDs are displayed instead of device names.  -L, resolve symlinks,
and -P, display full disk paths, do nothing at the moment.
The use of special vdevs is backward compatible for read-only access, so
root pools should be bootable, but exercise caution.

066d9631cb Fix inconsistencies in anonymous DOF files.
The DOF file output by dtrace -A contains only the loadable sections.
However, as it was created by a call to dtrace_dof_create() without
flags, the original DOF was created with the loadable sections.  The
result is that the DOF includes the section headers for the unloadable
sections (COMMENTS and UTSNAME) without these sections actually being
present.  This is inconsistent.

A simple change to anon_prog() ensures that the missing sections are
present in the outputted DOF.  Alternatively, the call to
dtrace_dof_create() could pass the DTRACE_D_STRIP flag stripping out the
loadable sections.  As the unloadable sections contain info useful for
debugging purposes they haven't been stripped.

2d54db4cc9 fix up r354804, link zstreamdump with libzfs
Since r354804 libzpool depends on libzfs for get_system_hostid symbol.
Except for zstreamdump, all binaries linked with libzpool were already
linked with libzfs.  So, zstreamdump is the only fall-out.

It's interesting that on amd64 not only I was able to successfully build
zstreamdump, I am able to run it despite having the unresolved symbol in
libzpool.

illumos/illumos-gate@9c2acf00e2
9c2acf00e2

https://www.illumos.org/issues/10554
  During the port of MMP (illumos bug 10499) from ZoL, I found this
  earlier ZoL project is a prerequisite. Here is the original
  description.  This addition will enable us to sync an open TXG to the
  main pool on demand. The functionality is similar to 'sync(2)' but
  'zpool sync' will return when data has hit the main storage instead of
  potentially just the ZIL as is the case with the 'sync(2)' cmd.

1af3a11218 MFZoL: Avoid retrieving unused snapshot props
This patch modifies the zfs_ioc_snapshot_list_next() ioctl to enable it
to take input parameters that alter the way looping through the list of
snapshots is performed. The idea here is to restrict functions that
throw away some of the snapshots returned by the ioctl to a range of
snapshots that these functions actually use. This improves efficiency
and execution speed for some rollback and send operations.

This updates FreeBSD large_dnode code (that was imported from ZoL) to a

improvements and fixes comparing to what we have in FreeBSD now.
I think that the most significant update is 8199 multi-threaded
dmu_object_alloc().

This commit reverts r351077 that was a revert of r351074 and r351076 and
restores those changes.  Required atomic operations should be available

912c3fe715 ZFS: add bookmark renaming
The feature is implemented as an extension of the existing
ZFS_IOC_RENAME ioctl.  Both the userland and the DSL interfaces support
renaming only a single bookmark at a time.  As of now, there is no ZCP
interface to the new functionality.  I am going to add it once the DSL
interface passes a test of time.

This change picks up support for zfs_ioc_namecheck_t::ENTITY_NAME that
was added to ZoL as part of Redacted Send/Receive feature by Paul
Dagnelie <pcd@delphix.com>.  This is needed to allow a bookmark name in
zc_name.

  Remove unnecessary txg syncs from receive_object() Closes #7197

This updates FreeBSD large_dnode code (that was imported from ZoL) to a version
that was committed to illumos.  It has some cleanups, improvements and fixes
comparing to what we have in FreeBSD now.  I think that the most significant
update is 8199 multi-threaded dmu_object_alloc().

4139761bb5 MFV r350896: 6585 sha512, skein, and edonr have an unenforced dependency on extensible dataset

https://www.illumos.org/issues/6585
  In any pool without the extensible dataset feature flag already enabled,
  creating a dataset with dedup set to use one of the new checksums would result
  in the following panic as soon as any data was added:
  panic[cpu0]/thread=ffffff0006761c40: feature_get_refcount(spa, feature,
  &refcount) != 48 (0x30 != 0x30), file: ../../common/fs/zfs/zfeature.c line 390

  ffffff0006761830 fffffffffba8fbdd ()
  ffffff0006761890 zfs:feature_do_action+11a ()
  ffffff00067618c0 zfs:spa_feature_incr+1e ()
  ffffff0006761920 zfs:dmu_object_zapify+b7 ()

  ffffff0006761c20 zfs:txg_sync_thread+227 ()
  ffffff0006761c30 unix:thread_start+8 ()
  Inspection showed that feature->fi_feature was 7, which is the value of
  SPA_FEATURE_EXTENSIBLE_DATASET in the spa_feature enum.
  Testing shows that the panic can be prevented by explicitly setting extensible
  dataset as a dependency for the sha512, edonr, and skein feature flags.
  Alternatively, the new checksums code could possibly be changed to obviate the
  need for the dependency.

Many thanks to cryx-freebsd@h3q.com for reporting the problem and
submitting a fix.  I have chosen to take an equivalent but textually
different patch from ZoL just to avoid increasing divergence between
OpenZFS flavours.

f34d9e5d6b Fix a bug introduced with parallel mounting of zfs
Incorporate a fix from zol:
ab5036df1c

commit log from upstream:
 Fix race in parallel mount's thread dispatching algorithm

Strategy of parallel mount is as follows.

1) Initial thread dispatching is to select sets of mount points that
 don't have dependencies on other sets, hence threads can/should run
 lock-less and shouldn't race with other threads for other sets. Each
 thread dispatched corresponds to top level directory which may or may
 not have datasets to be mounted on sub directories.

2) Subsequent recursive thread dispatching for each thread from 1)
 is to mount datasets for each set of mount points. The mount points
 within each set have dependencies (i.e. child directories), so child
 directories are processed only after parent directory completes.

The problem is that the initial thread dispatching in
zfs_foreach_mountpoint() can be multi-threaded when it needs to be
single-threaded, and this puts threads under race condition. This race
appeared as mount/unmount issues on ZoL for ZoL having different
timing regarding mount(2) execution due to fork(2)/exec(2) of mount(8).
`zfs unmount -a` which expects proper mount order can't unmount if the
mounts were reordered by the race condition.

There are currently two known patterns of input list `handles` in
`zfs_foreach_mountpoint(..,handles,..)` which cause the race condition.

1) #8833 case where input is `/a /a /a/b` after sorting.
 The problem is that libzfs_path_contains() can't correctly handle an
 input list with two same top level directories.
 There is a race between two POSIX threads A and B,
  * ThreadA for "/a" for test1 and "/a/b"
  * ThreadB for "/a" for test0/a
 and in case of #8833, ThreadA won the race. Two threads were created
 because "/a" wasn't considered as `"/a" contains "/a"`.

2) #8450 case where input is `/ /var/data /var/data/test` after sorting.
 The problem is that libzfs_path_contains() can't correctly handle an
 input list containing "/".
 There is a race between two POSIX threads A and B,
  * ThreadA for "/" and "/var/data/test"
  * ThreadB for "/var/data"
 and in case of #8450, ThreadA won the race. Two threads were created
 because "/var/data" wasn't considered as `"/" contains "/var/data"`.
 In other words, if there is (at least one) "/" in the input list,
 the initial thread dispatching must be single-threaded since every
 directory is a child of "/", meaning they all directly or indirectly
 depend on "/".

In both cases, the first non_descendant_idx() call fails to correctly
determine "path1-contains-path2", and as a result the initial thread
dispatching creates another thread when it needs to be single-threaded.
Fix a conditional in libzfs_path_contains() to consider above two.
