The code imported from opensolaris was depending on ping supporting
UDP for sending probes. Since this is not supported by ping on FreeBSD
use a perl script instead.
The remote test requires the usage of ksh93, so state that in the

Enable the local test, but keep the remote test disabled, since it
requires a remote machine on the LAN.

Since we don't have /usr/bin/ksh, use a generic way of specifying
ksh. Some of the tests only run with ksh93, so use this shell

so fix this, too.

In some cases, the required information is not available and the
UDP provider reported an empty string in this case and the IP

This patch changes the value provided in this case to the string
"<unknown>". This make the behaviour consistent and in-line with

During scans (scrubs or resilvers), it sorts the blocks in each transaction
group by block offset; the result can be a significant improvement. (On my
test system just now, which I put some effort to introduce fragmentation into
the pool since I set it up yesterday, a scrub went from 1h2m to 33.5m with the
changes.) I've seen similar rations on production systems.

This patch adds a new socket option, SO_REUSEPORT_LB, which allow multiple
programs or threads to bind to the same port and incoming connections will be
load balanced using a hash function.
Most of the code was copied from a similar patch for DragonflyBSD.
However, in DragonflyBSD, load balancing is a global on/off setting and can not
be set per socket. This patch allows for simultaneous use of both the current
SO_REUSEPORT and the new SO_REUSEPORT_LB options on the same system.
Required changes to structures:
Globally change so_options from 16 to 32 bit value to allow for more options.
Add hashtable in pcbinfo to hold all SO_REUSEPORT_LB sockets.
Limitations:
As DragonflyBSD, a load balance group is limited to 256 pcbs (256 programs or
threads sharing the same socket).
This is a substantially different contribution as compared to its original
incarnation at svn r332894 and reverted at svn r332967. Thanks to rwatson@

dwatch allows you to customnize the predicate (condition) for when
information is displayed. The DTrace syntax for this is:
probe[, ...] /predicate/ { [actions] }
But if predicate is something like "*args[1]!=NULL" to test that
the first pointer in an array is non-NULL, the syntax produced is:
probe[, ...] /*arg1!=NULL/ { [actions] }
The issue being that "/*" is the beginning of a comment and thus
the following error is emitted:
dtrace: failed to compile script /dev/stdin:
line 535: /* encountered inside a comment
This patch adds whitespace around the argument given to -t,
producing:
probe[, ...] / *arg1!=NULL / { [actions] }

If you were to pass an invalid option after `-B num' or `-K num' you
would see that the usage statement would show the value you passed
instead of the actual default.
Moving the default values to separate variables that are unaffected
by the options-parsing allows the usage statement to correctly show
the hard-coded default values if no flags are used.

In recently added sendrecv profile, there was a line purposefully
added to introduce a compilation error in which `-dev' is used to
debug the entry. Removing the entry.
Sponsored by: Smule, Inc.
The options `-d' (debug), `-e' (exit after compile), and `-v' (verbose)
when combined in any order (though best remembered as `-dev') will run
the conflated script through dtrace(1), test for error conditions, and
show the line that dtrace(1) failed at (with context).
If no errors are found, the output is the same as `-e[v]'.
When writing a new profile for dwatch(1), you can quickly test to
make sure it compiles by running `dwatch -devX profile_name' where
profiles live in /usr/libexec/dwatch or /usr/local/libexec/dwatch
(the latter being where profiles installed via ports should go).

The change adds -t <name> option to zpool create and -t option to zpool
import in its form with an old name and a new name. This allows to
import (or create) a pool under a name that's different from its real,
permanent name without affecting that name. This is useful when working
with VM images or images of other physical systems if they happen to
have a ZFS pool with the same name as the host system.
The changes come from ZoL with some small tweaks.

9235 rename zpool_rewind_policy_t to zpool_load_policy_t
illumos/illumos-gate@5dafeea3eb
We want to be able to pass various settings during import/open of a pool,
which are not only related to rewind. Instead of adding a new policy and
duplicate a bunch of code, we should just rename rewind_policy to a more
generic term like load_policy.
For instance, we'd like to set spa->spa_import_flags from the nvlist,
rather from a flags parameter passed to spa_import as in some cases we want
those flags not only for the import case, but also for the open case. One
such flag could be ZFS_IMPORT_MISSING_LOG (as used in zdb) which would
allow zfs to open a pool when logs are missing.

The idea of Storage Pool Checkpoint (aka zpool checkpoint) deals with
exactly that. It can be thought of as a “pool-wide snapshot” (or a
variation of extreme rewind that doesn’t corrupt your data). It remembers
the entire state of the pool at the point that it was taken and the user
can revert back to it later or discard it. Its generic use case is an
administrator that is about to perform a set of destructive actions to ZFS
as part of a critical procedure. She takes a checkpoint of the pool before
performing the actions, then rewinds back to it if one of them fails or puts
the pool into an unexpected state. Otherwise, she discards it. With the
assumption that no one else is making modifications to ZFS, she basically
wraps all these actions into a “high-level transaction”.
