When spare or l2cache device path changes, zpool import will not fix up
their paths like normal vdev. The issue is that when you supply a pool
name argument to zpool import, it will use it to filter out device which
doesn't have the pool name in the label. Since spare and l2cache device
never have that in the label, they'll always get filtered out.
We fix this by making sure we never filter out a spare or l2cache
device.

This patch adds a '-f' option to 'zpool offline' to fault a vdev

autoreplace and triggering the slot fault LED. The -f faults

This allows users to specify "-o property=value" to override and
"-x property" to exclude properties when receiving a zfs send stream.
Both native and user properties can be specified.
This is useful when using zfs send/receive for periodic
backup/replication because it lets users change properties such as
canmount, mountpoint, or compression without modifying the source.

Document the existence of `createtxg` and `guid` native properties
in man pages and zfs command output.
One of the great features of ZFS is incremental replication of
snapshots, possibly between pools on different machines.
Shell scripts are commonly used to auomate this procedure. They have to
find the most recent common snapshot between both sides and then
perform incremental send & recv.
Currently, scripts rely on the sorting order of `zfs list`, which
defaults to `createtxg`, and the assumption that snapshot names on
either side do not change.
By making `createtxg` and `guid` part of the public ZFS interface,
scripts are enabled to use
a) `createtxg` to determine the logical & temporal order of snapshots
(the creation property is not an equivalent substitute since
multiple snapshots may be created within one second)
b) `guid` to uniquely identify a snapshot, independent of its current
display name
This has the potential of making scripts safer and correct.

This commit allow higher ashift values (up to 16) in 'zpool create'
The ashift value was previously limited to 13 (8K block) in b41c990
because the limited number of uberblocks we could fit in the
statically sized (128K) vdev label ring buffer could prevent the
ability the safely roll back a pool to recover it.

allow us to store a minimum number of 16 uberblocks in the vdev
label, even with higher ashift values.

This patch updates the "zpool status/iostat -c" commands to only run
"pre-baked" scripts from the /etc/zfs/zpool.d directory (or wherever
you install to). The scripts can only be run from -c as an unprivileged
user (unless the ZPOOL_SCRIPTS_AS_ROOT environment var is
set by root). This was done to encourage scripts to be written is such
a way that normal users can use them, and to be cautious. If your
script needs to run a privileged command, consider adding the
appropriate line in /etc/sudoers. See zpool(8) for an example of how
to do this.
The patch also allows the scripts to output custom column names. If
the script outputs a line like:
name=value
then "name" is used for the column name, and "value" is its value.
Multiple columns can be specified by outputting multiple lines. Column
names and values can have spaces. If the value is empty, a dash (-) is
printed instead.
After all the "name=value" lines are read (if any), zpool will take the
next the next line of output (if any) and print it without a column
header. After that, no more lines will be processed. This can be
useful for printing errors.
Lastly, this patch also disables the -c option with the latency and
request size histograms, since it produced awkward output and made the
code harder to maintain.

In glibc 2.5, makedev(), major(), and minor() are defined in
sys/sysmacros.h. They are also defined in types.h for backward
compatability, but using these definitions triggers a compile warning.
This breaks the ZFS build, as it builds with -Werror.
autoconf email threads indicate these macros may be defined in
sys/mkdev.h in some cases.
This commit adds configure checks to detect where makedev() is defined:
sys/sysmacros.h
sys/mkdev.h
It assumes major() and minor() are defined in the same place.
The libspl types.h then includes
sys/sysmacros.h (preferred) or
sys/mkdev.h (2nd choice)
if one of those defines makedev().
This is done before including the system types.h.
An alternative would be to remove uses of major, minor, and makedev,
instead comparing the st_dev returned from stat64. These configure
checks would then be unnecessary.
This change revealed that __NORETURN was being defined unnecessarily in
libspl/include/sys/sysmacros.h. That definition is removed.
The files in which __NORETURN are used all include types.h, and so all
will get the definition provided by feature_tests.h

The current implementation for allowing nfs to access snapdir is very buggy.
It uses a special fh for snapdirs, such that the next time nfsd does
fh_to_dentry, it actually returns the root inode inside the snapshot. So nfsd
never knows it cross a mountpoint.
The problem is that nfsd will not hold a reference on the vfsmount of the
snapshot. This cause auto unmounter to unmount the snapshot even though nfs is
still holding dentries in it.
To fix this, we return the inode for the snapdirs themselves. However, we also
trigger automount upon fh_to_dentry, and return ESTALE so nfsd will revalidate
and see the mountpoint and do crossmnt.
Because nfsd will now be aware that these are different filesystems users
must add crossmnt to their export options to access snapshot directories.

The problem is that consumers of `libZFS_Core` that forget to call
`libzfs_core_init()` before calling any other function of the library
are having a hard time realizing their mistake. The library's internal
file descriptor is declared as global static, which is ok, but it is not
initialized explicitly; therefore, it defaults to 0, which is a valid
file descriptor. If `libzfs_core_init()`, which explicitly initializes
the correct fd, is skipped, the ioctl functions return errors that do
not have anything to do with `libZFS_Core`, where the problem is
actually located.
Even though assertions for that existed within `libZFS_Core` for debug
builds, they were never enabled because the `-DDEBUG` flag was missing
from the compiler flags.
This patch applies the following changes:
1. It adds `-DDEBUG` for debug builds of `libZFS_Core` and `libzfs`,
to enable their assertions on debug builds.
2. It corrects an assertion within `libzfs`, where a function had
been spelled incorrectly (`zpool_prop_unsupported()`) and nobody
knew because the `-DDEBUG` flag was missing, and the preprocessor
was taking that part of the code away.
3. The library's internal fd is initialized to `-1` and `VERIFY`
assertions have been placed to check that the fd is not equal to
`-1` before issuing any ioctl. It is important here to note, that
the `VERIFY` assertions exist in both debug and non-debug builds.
4. In `libzfs_core_fini` we make sure to never increment the
refcount of our fd below 0, and also reset the fd to `-1` when no
one refers to it. The reason for this, is for the rare case that
the consumer closes all references but then calls one of the
library's functions without using `libzfs_core_init()` first, and
in the mean time, a previous call to `open()` decided to reuse
our previous fd. This scenario would have passed our assertion in
non-debug builds.
5. Once the `ASSERTION` macros were enabled again, two tests from
the test suite were failing in `libzfs_sendrecv.c` at a
`ZIO_CHECKSUM_IS_ZERO` check within `dump_record()`. We now zero
the kernel filled checksums in all `dmu_replay_record`s that we
read in `cksummer()`, except the ones that are of type
`DRR_BEGIN`.
I considered making all assertions available for both debug and
non-debug builds, but I figured that it would not be appropriate if, for
example, an outside consumer of `libZFS_Core` suddenly triggers an
assertion failure because they happened to call `libzfs_core_fini()`,
even if previously the reference counter was `0`. Therefore, all the
reference counter related assertions are only enabled for debug builds,
and fd related assertions are enabled for debug and non-debug builds.
Porting notes:
- `ASSERT3S(g_refcount, >, 0);` added to `recv_impl` in
lib/libzfs_core/libzfs_core.c .

This ioctl returns the config of the pool in a buffer pre-allocated in
userland. The original estimate for the size is too conservative since
it doesn't account for the large size of vdev stats that are added to
the config before returning.
This fix simply increases the size of the buffer passed. This results in
a speed up of the zpool import process, and less spam in zfs_dbgmsg.

Porting notes:
- statvfs64 is replaced by statfs64.
- ZFS_SUPER_MAGIC definition moved in include/sys/fs/zfs.h

Porting notes:
- Several direct callers of zk_thread_create() are passing TS_RUN for the
length. The `len` and `state` were inverted,this commit fixes them.
