Porting Notes:
- Updated 'zpool labelclear' and 'zdb -l' such that they attempt
to find a vdev given solely its short name. This behavior is
consistent with the upstream OpenZFS code and the test cases
depend on it. The actual implementation differs slightly due
to device naming conventions on Linux.
- auto_online_001_pos, auto_replace_001_pos and add-o_ashift
test cases updated to expect failure when no label exists.
- read_efi_label() and zpool_label_disk_check() are read-only
operations and should use O_RDONLY at open time to enforce this.
- zpool_label_disk() and zpool_relabel_disk() write the partition
information using O_DIRECT an fsync() and page cache invalidation
to ensure a consistent view of the device.
- dump_label() in zdb should invalidate the page cache in order
to get the authoritative label from disk.

recv_incremental_replication() takes care of things like removing
datasets that have been removed on the sending side, detecting renamed
datasets, ensuring that all datasets in the affected hierarchy have the
same properties as their counterparts on the sending side.
All of the above are not necessary if we are receiving a stream for a
single dataset that has been generated with zfs send -p, that is, a
stream that includes properties. zfs_receive_one() already takes care
of applying the properties to the received datasets.

When a pool is suspended it's impossible to read the list

misleading "insufficient permissions" error message.
Update zpool_get_errlog() to use the standard zpool error
logging functions to generate a useful error message. In
this case:
errors: List of errors unavailable: pool I/O is currently suspended
This patch does not address the related issue of potentially
not being able to resume a suspend pool when the underlying

Additionally, remove the error handling from zfs_alloc()
in zpool_get_errlog() for readability since this function

OpenZFS-commit: https://github.com/openzfs/openzfs/commit/2ad25b4Closes#5689
Porting notes:
- tests/zfs-tests/tests/functional/cli_root/zfs_receive/zfs_receive_013_pos.ksh
renamed as zfs_receive_015_pos.ksh, zfs_receive_013_pos.ksh is now
used for OpenZFS test.
- libzfs_sendrecv.c: SMALLEST_POSSIBLE_MAX_DDT_MB is always used
for all 32-bit builds.
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 .

The refresh_config() calls into the kernel with ZFS_IOC_POOL_TRYIMPORT.
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.

This patch adds a command (-c) option to zpool status and zpool iostat. The
-c option allows you to run an arbitrary command on each vdev and display
the first line of output in zpool status/iostat. The environment vars
VDEV_PATH and VDEV_UPATH are set to the vdev's path and "underlying path"
before running the command. For device mapper, multipath, or partitioned
vdevs, VDEV_UPATH is the actual underlying /dev/sd* disk. This can be useful
if the command you're running requires a /dev/sd* device.
The patch also uses /sys/block/<dev>/slaves/ to lookup the underlying device
instead of using libdevmapper. This not only removes the libdevmapper
requirement at build time, but also allows you to resolve device mapper
devices without being root. This means that UDEV_UPATH get set correctly
when running zpool status/iostat as an unprivileged user.
Example:
$ zpool status -c 'echo I am $VDEV_PATH, $VDEV_UPATH'

Failure to do so can result in a result in the vdev appearing
as UNAVAIL when the vdev path provided to the kernel can't be

This patch addresses multiple 'zpool import' block device
indentification problems which are most likely to occur on a
system configured to use blkid, by_vdev paths, multipath and
failover. The symptom most commonly observed is the import
uses different path names to import the pool than would
normally be expected.
* When using blkid to identify vdevs the listed devices may
be added to the cache in any order. In order to apply the
preferred search order heuristic a zfs_path_order() function
was added to calculate the order given full path names.
* Since it's possible to have multiple block devices with
different vdev guids which refer to the same ZPOOL_CONFIG_PATH
the slice cache must be indexed by guid and name. By avoiding
collisions the preferred ordering can be maintaining even
when multiple block devices claim the same ZPOOL_CONFIG_PATH.
The preferred sorting by partition was never benefitial for
a Linux system and was removed as part of this change.
* When adding entries to the blkid cache avl_find/avl_insert
are used instead of avl_add because collisions are possible
and must be handled gracefully.
* For pools using multipath devices there are, at a minimum,
three devices where a vdev label may be read. They are the
dm-* device and each underlying /dev/sd* device. Due to the
way the block cache is implemented each of these devices may
have a different cached copy of the vdev label. This can
result in "ghost pools" which appear to persist even after
a 'zpool labelclear' has been done to the dm-* device. In
order to prevent this the vdev label is read with O_DIRECT
in order to bypass any caching to get the on-disk version.
* When opening a block device verify that vdev guid read from
the disk matches the expected vdev guid. This allows for bad
labels to be filtered out.

Previously when a drive faulted, the statechange-led.sh script would lookup
the drive's LED sysfs entry in /sys/block/sd*/device/enclosure_device, and
turn it on. During testing we noticed that if you pulled out a drive, or if
the drive was so badly broken that it no longer appeared to Linux, that the
/sys/block/sd* path would be removed, and the script could not lookup the
LED entry.
To fix this, this patch looks up the disks's more persistent
"/sys/class/enclosure/X:X:X:X/Slot N" LED sysfs path at pool import. It then
passes that path to the statechange-led script to use, rather than having the
script look it up on the fly. This allows the script to turn on/off the slot
LEDs even when the drive is missing.
