af63bbd0f0 zfsd: Don't spare a vdev that's being replaced
If a zfs pool contains a replacing vdev (either created manually by "zpool
replace" or by zfsd(8) via autoreplace by physical path) and then new spares
get added to the pool, zfsd shouldn't use one to replace the drive that is
already being replaced.  That's a waste of resources that just slows down
the rebuild.

0d6993dfd3 MFV r328255: 8972 zfs holds: In scripted mode, do not pad columns with spaces
illumos/illumos-gate@e9b7d6e7f7

https://www.illumos.org/issues/8972:
'zfs holds -H' does not properly output content in scripted mode. It uses a
tab instead of two spaces, but it still pads column widths with spaces when
it should not.

4eb2803697 MFV r328251: 8652 Tautological comparisons with ZPROP_INVAL
illumos/illumos-gate@4ae5f5f06c

https://www.illumos.org/issues/8652:
Clang and GCC prefer to use unsigned ints to store enums. With Clang, that
causes tautological comparison warnings when comparing a zfs_prop_t or
zpool_prop_t variable to the macro ZPROP_INVAL. It's likely that error
handling code is being silently removed as a result.

8641 "zpool clear" and "zinject" don't work on "spare" or "replacing" vdevs

illumos/illumos-gate@2ba5f978a4

https://www.illumos.org/issues/8641:
"zpool clear" and "zinject -d" can both operate on specific vdevs, either
leaf or interior. However, due to an oversight, neither works on a "spare"

Even though there was nothing to clear, those commands shouldn't have

$ sudo zpool clear foo raidz1-0

illumos/illumos-gate@a3b2868063

https://www.illumos.org/issues/8677
  We want to be able to run channel programs outside of synching context.
  This would greatly improve performance of channel program that just gather
  information, as we won't have to wait for synching context anymore.

  This feature should introduce the following:
  - A new command line flag in "zfs program" to specify our intention to
  run in open context.
  - A new flag/option within the channel program ioctl which selects the
  context.
  - Appropriate error handling whenever we try a channel program in
  open-context that contains zfs.sync* expressions.
  - Documentation for the new feature in the manual pages.

fd74a38251 zdb: use a heap allocation instead of a huge array on stack
SPA_MAXBLOCKSIZE is 16 MB and having such a large object on the stack is
not nice in general and it could cause some confusing failures in the

483f7100b4 Annotate pragma/err.invalidlibdep.ksh as EXFAIL.
The test creates a D library with a "depends_on library" pragma
referencing a non-existent library, and expects compilation to fail.
However, as far as I can tell, libdtrace is supposed simply abort
compilation of the library in this case, and continue. This behaviour
is desirable when adding libraries which depend on optional KLDs, for
example.

When we encounter a USDT probe in a weak symbol, we emit an alias for
the probe function symbol. Such aliases are named differently from the
aliases we emit for probes in local functions, so make sure to take that
difference into account when resizing the output object file's string
table. Otherwise, we underrun the string table buffer.

1c05a6ea6b MFV r325013,r325034: 640 number_to_scaled_string is duplicated in several commands
illumos/illumos-gate@0a0551200e
0a0551200e

https://www.illumos.org/issues/640
  du(1), df(1m), ls(1), and swap(1m) all include a copy (it appears literally
  copied) of the 'number_to_scaled_string' function in their source. This should
  be moved to a shared library and all 4 commands should use this instead.

FreeBSD note: of all libcmdutils functionality ZFS (and other illumos
contrib code) currently uses only nicenum() function (which is similar
to humanize_number but has some formatting differences).  For this
reason I decided to not port the whole library.  As a result, nicenum.c
from libcmdutils is compiled into libzfs and libzpool.  This is a bit
ugly, but works.  If one day we are forced to create libillumos, then
the file should be moved to that library.

illumos/illumos-gate@aab04418a7
aab04418a7

https://www.illumos.org/issues/6268
  The zfs diff command presents a description of the changes that have occurred
  to files within a filesystem between two snapshots. If a file is renamed, the
  tool is capable of reporting this, e.g.:
  cd /some/zfs/dataset/subdir
  mv file0 file1
  Will result in a diff record like:
  R        /some/zfs/dataset/subdir/file0  ->  /some/zfs/dataset/subdir/file1
  Unfortunately, it seems that rename detection only uses the base filename to
  determine if a file has been renamed or simply modified. This leads to
  misreporting only the original filename, omitting the more relevant destination
  filename entirely. For example:
  cd /some/zfs/dataset/subdir
  mv file0 ../otherdir/file0
  Will result in a diff entry:
  M        /some/zfs/dataset/subdir/file0
  But it should really emit:
  R        /some/zfs/dataset/subdir/file0  ->  /some/zfs/dataset/otherdir/file0

https://www.illumos.org/issues/7571
  ZFS displays the default value for non-present readonly numeric (and index)
  properties. However, these properties default values are not meaningful.
  Instead, we should display a "-", indicating that they are not present. For
  example, on a version-12 pool, the usedby* properties are not available, but
  they show up as the incorrect value "0":
     1. zfs get all test12
        ...

        test12 usedbydataset 0 -

f51efc68f6 MFV r316864: 6392 zdb: introduce -V for verbatim import
illumos/illumos-gate@dfd5965f7e
dfd5965f7e

FreeBSD note: the manual page is to be updated separately.

https://www.illumos.org/issues/6392
  When given a pool name via -e, zdb would attempt an import. If it
  failed, then it would attempt a verbatim import. This behavior is
  not always desirable so a -V switch is added to zdb to control the
  behavior. When specified, a verbatim import is done. Otherwise,
  the behavior is as it was previously, except no verbatim import
  is done on failure.

65512687a9 MFV r316862: 6410 teach zdb to perform object lookups by path
illumos/illumos-gate@ed61ec1da9
ed61ec1da9

FreeBSD note: this commit does not update the manual page.
The original change includes conversion of the manual page from *roff format
to mandoc format.  So, it is hard to extract the content change from
that.  I am going to replace our zdb manual page, which is an earlier
independent conversion, with a slighly modified version of the upstream page.

  This is primarily intended to ease debugging & testing ZFS when one is only
  interested in things like the on-disk location of a specific object's blocks,
  but doesn't know their object id. This allows doing things like the following
  (FreeBSD-based example):
          # zpool create -f foo da0
          # dd if=/dev/zero of=/foo/1 bs=1M count=4 >/dev/null 2>&1
          # zpool export foo
          # zdb -vvvvv -o "ZFS plain file" foo /1
          Object  lvl   iblk   dblk  dsize  lsize   %full  type

7280 Allow changing global libzpool variables in zdb and ztest through command line

illumos/illumos-gate@0e60744c98
0e60744c98

https://www.illumos.org/issues/7280
  zdb is very handy for diagnosing problems with a pool in a safe and
  quick way. When a pool is in a bad shape, we often want to disable some
  fail-safes, or adjust some tunables in order to open them. In the
  kernel, this is done by changing public variables in mdb. The goal of
  this feature is to add the same capability to zdb and ztest, so that
  they can change libzpool tuneables from the command line.

illumos/illumos-gate@2840dce1a0
2840dce1a0

https://www.illumos.org/issues/8600
  ZFS channel programs should be able to create snapshots.
  In addition to the base snapshot functionality, this will likely entail adding
  extra logic to handle edge cases which were formerly not possible, such as
  creating then destroying a snapshot in the same transaction sync.
