The following options have been added to the zpool add, iostat,
list, status, and split subcommands. The default behavior was
not modified, from zfs(8).
-g Display vdev GUIDs instead of the normal short
device names. These GUIDs can be used in-place of
device names for the zpool detach/off‐
line/remove/replace commands.
-L Display real paths for vdevs resolving all symbolic
links. This can be used to lookup the current block
device name regardless of the /dev/disk/ path used
to open it.
-p Display full paths for vdevs instead of only the
last component of the path. This can be used in
conjunction with the -L flag.
This behavior may also be enabled using the following environment
variables.
ZPOOL_VDEV_NAME_GUID
ZPOOL_VDEV_NAME_FOLLOW_LINKS
ZPOOL_VDEV_NAME_PATH
This change is based on worked originally started by Richard Yao
to add a -g option. Then extended by @ilovezfs to add a -L option
for openzfsonosx. Those changes have been merged, re-factored,
a -p option added and extended to all relevant zpool subcommands.

Porting notes:
- This change was originally never ported to Linux due to it
dependence on the thread pool interface. This patch solves
that issue by switching the code to use the existing taskq
implementation which provides the same basic functionality.
However, in order for this to work properly thread_init()
and thread_fini() must be called around to taskq consumer
to perform the needed thread initialization.
- The check_one_slice, nozpool_all_slices, and check_slices
functions have been disabled for Linux. They are difficult,
but possible, to implement for Linux due to how partitions
are get names. Since this is only an optimization this code
can be added at a latter date.

ZFS incorrectly uses directory-based extended attributes even when
xattr=sa is specified as a dataset property or mount option. Support to
honor temporary mount options including "xattr" was added in commit
0282c4137e. There are two issues with the
mount option handling:
* Libzfs has historically included "xattr" in its list of default mount
options. This overrides the dataset property, so the dataset is always
configured to use directory-based xattrs even when the xattr dataset
property is set to off or sa. Address this by removing "xattr" from
the set of default mount options in libzfs.
* There was no way to enable system attribute-based extended attributes
using temporary mount options. Add the mount options "saxattr" and
"dirxattr" which enable the xattr behavior their names suggest. This
approach has the advantages of mirroring the valid xattr dataset
property values and following existing conventions for mount option
names.

This is critical because unlike filesystems, volumes will create a

While module loading itself is synchronous the creation of the /dev/zfs
device is not. This is because /dev/zfs is typically created by a udev
rule after the module is registered and presented to user space through
sysfs. This small window between module loading and device creation
can result in spurious failures of libzfs_init().
This patch closes that race by extending libzfs_init() so it can detect
that the modules are loaded and only if required wait for the /dev/zfs
device to be created. This allows scripts to reliably use the following
shell construct without the need for additional error handling.
$ /sbin/modprobe zfs && /sbin/zpool import -a
To minimize the potential time waiting in libzfs_init() a strategy
similar to adaptive mutexes is employed. The function will busy-wait
for up to 10ms based on the expectation that the modules were just
loaded and therefore the /dev/zfs will be created imminently. If it
takes longer than this it will fall back to polling for up to 10 seconds.
This behavior can be customized to some degree by setting the following
new environment variables. This functionality is provided for backwards
compatibility with existing scripts which depend on the module auto-load
behavior. By default module auto-loading is now disabled.
* ZFS_MODULE_LOADING="YES|yes|ON|on" - Attempt to load modules.
* ZFS_MODULE_TIMEOUT="<seconds>" - Seconds to wait for /dev/zfs
The zfs-import-* systemd service files have been updated to call
'/sbin/modprobe zfs' so they no longer rely on the legacy auto-loading
behavior.

Porting Notes:
* Included in this patch is a tiny ISP2() cleanup in zio_init() from
Illumos 5255.
* Unlike the upstream Illumos commit this patch does not impose an
arbitrary 128K block size limit on volumes. Volumes, like filesystems,
are limited by the zfs_max_recordsize=1M module option.
* By default the maximum record size is limited to 1M by the module
option zfs_max_recordsize. This value may be safely increased up to
16M which is the largest block size supported by the on-disk format.
At the moment, 1M blocks clearly offer a significant performance
improvement but the benefits of going beyond this for the majority
of workloads are less clear.
* The illumos version of this patch increased DMU_MAX_ACCESS to 32M.
This was determined not to be large enough when using 16M blocks
because the zfs_make_xattrdir() function will fail (EFBIG) when
assigning a TX. This was immediately observed under Linux because
all newly created files must have a security xattr created and
that was failing. Therefore, we've set DMU_MAX_ACCESS to 64M.
* On 32-bit platforms a hard limit of 1M is set for blocks due
to the limited virtual address space. We should be able to relax
this one the ABD patches are merged.

The umem_alloc_aligned() function should not assume that a 'void *'

complicating the ASSERT to handle this it is simply removed.
Additionally, the '%lu' format specifier should not be assumed to
imply a 64-bit value. Fix this by using the 'llu' format specifier
which will always be atleast 64-bit and explicitly casing the
variable to an u_longlong_t. This issue is handled the same way
in many other parts of the code.

As of this commit, volumes do not possess the version property in
any existing OpenZFS implementation. The zpool upgrade code, however,
uses zfs_prop_get_int() to fetch the version property of all children in
a pool. The semantics of the function, however, demand that it only be
used for known valid properties so it returns a garbage value for volumes.
This patch causes the version of a volume to appear to callers using
the zfs_prop_get_int() API to be that of the default ZPL version for
the implementation. In the future, should volumes gain the property,
its actual value will be used.

way incomplete. Preferring names with fully intact labels helps weed out
bad paths and improves the likelihood of being able to import the pool.

I noticed when reviewing documentation that it is possible for user
space to use fctnl(fd, F_SETPIPE_SZ, (unsigned long) size) to change
the kernel pipe buffer size on Linux to increase the pipe size up to
the value specified in /proc/sys/fs/pipe-max-size. There are users using
mbuffer to improve zfs recv performance when piping over the network, so
it seems advantageous to integrate such functionality directly into the
zfs recv tool. This avoids the addition of two buffers and two copies
(one for the buffer mbuffer adds and another for the additional pipe),
so it should be more efficient.
This could have been made configurable and/or this could have changed
the value back to the original after we were done with the file
descriptor, but I do not see a strong case for doing either, so I
went with a simple implementation.

In order to accelerate zfs receive operations in the face of many
property-containing snapshots, commit 0574855 changed the header nvlist

snapshots; it would remove any snapshot which wasn't listed in the header
nvlist.
This patch restores the full list of snapshots in fss[<id>[snaps]] but
still suppresses the properties of non-sent snapshots and also removes a
consistency check in which an error is raised if a listed snapshot does
not have any properties in fss[<id>[snapprops]].

When importing pools with zpool import -aN there is inconsistent
behavior between '-d /dev/disk/by-id' (or another path) and
'-c /etc/zfs/zpool.cache'.
The difference in behavior is caused by zpool_find_import_cached()
returning an empty nvlist_t when there are no pools to import but
zpool_find_import_impl() returns NULL for the same situation. The
behavior of zpool_find_import_cached() is arguably more correct
because it allows returning NULL to be used for an error case and
not an empty set.
This change resolves the issue by updating get_configs() such that
it returns an empty set instead of NULL when no config is found.
The updated behavior will now always return 0 for this case.

Issue #2729
Creating virtual machines that have their rootfs on ZFS on hosts that
have their rootfs on ZFS causes SPA namespace collisions when the
standard name rpool is used. The solution is either to give each guest
pool a name unique to the host, which is not always desireable, or boot
a VM environment containing an ISO image to install it, which is
cumbersome.
26b42f3f9d introduced `zpool import -t
...` to simplify situations where a host must access a guest's pool when
there is a SPA namespace conflict. We build upon that to introduce
`zpool import -t tname ...`. That allows us to create a pool whose
in-core name is tname, but whose on-disk name is the normal name
specified.
This simplifies the creation of machine images that use a rootfs on ZFS.
That benefits not only real world deployments, but also ZFSOnLinux
development by decreasing the time needed to perform rootfs on ZFS
experiments.

Closes#2688
When com.delphix:spacemap_histogram is disabled, the value of
fragmentation was printing as 18446744073709551615 (UINT64_MAX),
when it should print as '-'.
The issue was caused by a small mistake during the merge of
"4980 metaslabs should have a fragmentation metric."
upstream: https://github.com/illumos/illumos-gate/commit/2e4c998
ZoL: https://github.com/zfsonlinux/zfs/commit/f3a7f66
The problem is in zpool_get_prop_literal, where the handling of the
pool property ZPOOL_PROP_FRAGMENTATION was added to wrong the
section. In particular, ZPOOL_PROP_FRAGMENTATION should not be in
the section where zpool_get_state(zhp) == POOL_STATE_UNAVAIL, but
lower down after it's already been determined that the pool is in
fact available, which is where upstream illumos correctly has had
it.
Thanks to lundman for helping to track down this bug.

Closes#2664
Providing a pkg-config file makes is easy for 3rd party applications
to link against the libzfs libraries. It also allows the libzfs
developers to modify the list of required libraries and cflags
without breaking existing applications.
The following example illustrates how pkg-config can be used:
cc `pkg-config --cflags --libs libzfs` -o myapp myapp.c
/*
* myapp.c
*/
void main()
{
libzfs_handle_t *hdl;
hdl = libzfs_init();
if (hdl)
libzfs_fini(hdl);
}
