When the pool configuration contains a hole due to a previous device
removal ignore this top level vdev. Failure to do so will result in
the current configuration being assessed to have a non-uniform
replication level and the expected warning will be disabled.

Currently, scrubs and resilvers can take an extremely
long time to complete. This is largely due to the fact
that zfs scans process pools in logical order, as
determined by each block's bookmark. This makes sense
from a simplicity perspective, but blocks in zfs are
often scattered randomly across disks, particularly
due to zfs's copy-on-write mechanisms.
This patch improves performance by splitting scrubs
and resilvers into a metadata scanning phase and an IO
issuing phase. The metadata scan reads through the
structure of the pool and gathers an in-memory queue
of I/Os, sorted by size and offset on disk. The issuing
phase will then issue the scrub I/Os as sequentially as
possible, greatly improving performance.
This patch also updates and cleans up some of the scan
code which has not been updated in several years.

This change incorporates three major pieces:
The first change is a keystore that manages wrapping
and encryption keys for encrypted datasets. These
commands mostly involve manipulating the new
DSL Crypto Key ZAP Objects that live in the MOS. Each
encrypted dataset has its own DSL Crypto Key that is
protected with a user's key. This level of indirection
allows users to change their keys without re-encrypting
their entire datasets. The change implements the new
subcommands "zfs load-key", "zfs unload-key" and
"zfs change-key" which allow the user to manage their
encryption keys and settings. In addition, several new
flags and properties have been added to allow dataset
creation and to make mounting and unmounting more
convenient.
The second piece of this patch provides the ability to
encrypt, decyrpt, and authenticate protected datasets.
Each object set maintains a Merkel tree of Message
Authentication Codes that protect the lower layers,
similarly to how checksums are maintained. This part
impacts the zio layer, which handles the actual
encryption and generation of MACs, as well as the ARC
and DMU, which need to be able to handle encrypted
buffers and protected data.
The last addition is the ability to do raw, encrypted
sends and receives. The idea here is to send raw
encrypted and compressed data and receive it exactly
as is on a backup system. This means that the dataset
on the receiving system is protected using the same
user key that is in use on the sending side. By doing
so, datasets can be efficiently backed up to an
untrusted system without fear of data being
compromised.

OpenZFS provides a library called tpool which implements thread
pools for user space applications. Porting this library means
the zpool utility no longer needs to borrow the kernel mutex and
taskq interfaces from libzpool. This code was updated to use
the tpool library which behaves in a very similar fashion.
Porting libtpool was relatively straight forward and minimal
modifications were needed. The core changes were:
* Fully convert the library to use pthreads.
* Updated signal handling.
* lmalloc/lfree converted to calloc/free
* Implemented portable pthread_attr_clone() function.
Finally, update the build system such that libzpool.so is no
longer linked in to zfs(8), zpool(8), etc. All that is required
is libzfs to which the zcommon soures were added (which is the way
it always should have been). Removing the libzpool dependency
resulted in several build issues which needed to be resolved.
* Moved zfeature support to module/zcommon/zfeature_common.c
* Moved ratelimiting to to module/zfs/zfs_ratelimit.c
* Moved get_system_hostid() to lib/libspl/gethostid.c
* Removed use of cmn_err() in zcommon source

Turning the multihost property on requires that a hostid be set to allow
ZFS to determine when a foreign system is attemping to import a pool.
The error message instructing the user to set a hostid refers to
genhostid(1).
Genhostid(1) is not available on SUSE Linux. This commit adds a script
modeled after genhostid(1) for those users.
Zgenhostid checks for an /etc/hostid file; if it does not exist, it
creates one and stores a value. If the user has provided a hostid as an
argument, that value is used. Otherwise, a random hostid is generated
and stored.
This differs from the CENTOS 6/7 versions of genhostid, which overwrite
the /etc/hostid file even though their manpages state otherwise.
A man page for zgenhostid is added. The one for genhostid is in (1), but
I put zgenhostid in (8) because I believe it's more appropriate.
The mmp tests are modified to use zgenhostid to set the hostid instead
of using the spl_hostid module parameter. zgenhostid will not replace
an existing /etc/hostid file, so new mmp_clear_hostid calls are
required.

* zpool_create_011_neg - Fix to correctly create the extra partition.
Modified zpool_vdev.c to use fstat64_blk() wrapper which includes
the st_size even for block devices.
* zpool_create_012_neg - Updated to properly find swap devices.
* zpool_create_014_neg, zpool_create_015_neg - Updated to use
swap_setup() and swap_cleanup() wrappers which do the right thing
on Linux and Illumos. Removed '-n' option which succeeds under
Linux due to differences in the in-use checks.
* zpool_create_016_pos.ksh - Skipped test case isn't useful.
* zpool_create_020_pos - Added missing / to cleanup() function.
Remove cache file prior to test to ensure a clean environment
and avoid false positives.
* zpool_destroy_001_pos - Removed test case which creates a pool on
a zvol. This is more likely to deadlock under Linux and has never
been completely supported on any platform.
* zpool_destroy_002_pos - 'zpool destroy -f' is unsupported on Linux.
Mount point must not be busy in order to unmount them.
* zfs_destroy_001_pos - Handle EBUSY error which can occur with
volumes when racing with udev.
* zpool_expand_001_pos, zpool_expand_003_neg - Skip test on Linux
until adding zvols to pools is fully supported and deadlock free.
The test could be modified to use loop-back devices but it would
be preferable to use the test case as is for improved coverage.
* zpool_export_004_pos - Updated test case to such that it doesn't
depend on nested pools. Normal file vdev under /var/tmp are fine.
* zpool_import_all_001_pos - Updated to skip partition 1, which is

* zpool_upgrade_002_pos, zpool_upgrade_004_pos - Root cause addressed
by upstream OpenZFS commit 3b7f360.
* zpool_upgrade_007_pos - Disabled in test case due to known failure.
Opened issue https://github.com/zfsonlinux/zfs/issues/6112
* zvol_misc_002_pos - Updated to to use ext2.
* zvol_misc_001_neg, zvol_misc_003_neg, zvol_misc_004_pos,
zvol_misc_005_neg, zvol_misc_006_pos - Moved to skip list, these
test case could be updated to use Linux's crash dump facility.
* zvol_swap_* - Updated to use swap_setup/swap_cleanup helpers.

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.
Since b02fe35 the largest uberblock size we support is 8K: this
allow us to store a minimum number of 16 uberblocks in the vdev
label, even with higher ashift values.
Additionally change 'ashift' pool property behaviour: if set it will
be used as the default hint value in subsequent vdev operations
('zpool add', 'attach' and 'replace'). A custom ashift value can still

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.

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

When a pool is suspended it's impossible to read the list
of damaged files from disk. This would result in a generic
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
device names have changed.
Additionally, remove the error handling from zfs_alloc()
in zpool_get_errlog() for readability since this function
can never fail.

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'

Commit 519129f added support to multi-thread 'zpool import' for
the case where block devices are scanned for under /dev/. This
commit generalizes that logic and applies it to the case where
device names are acquired from libblkid.
The zpool_find_import_scan() and zpool_find_import_blkid()
functions create an AVL tree containing each device name. Each
entry in this tree is dispatched to a taskq where the function
zpool_open_func() validates the device by opening it and reading
the label. This may result in additional entries being added
to the tree and those device paths being verified.
This is largely how the upstream OpenZFS code behaves but due to
significant differences the non-Linux code has been dropped for
readability. Additionally, this code makes use of taskqs and
kmutexs which are normally not available to the command line tools.
Special care has been taken to allow their use in the import
functions.

ZFS allows for specific permissions to be delegated to normal users
with the `zfs allow` and `zfs unallow` commands. In addition, non-
privileged users should be able to run all of the following commands:
* zpool [list | iostat | status | get]
* zfs [list | get]
Historically this functionality was not available on Linux. In order
to add it the secpolicy_* functions needed to be implemented and mapped
to the equivalent Linux capability. Only then could the permissions on
the `/dev/zfs` be relaxed and the internal ZFS permission checks used.
Even with this change some limitations remain. Under Linux only the
root user is allowed to modify the namespace (unless it's a private
namespace). This means the mount, mountpoint, canmount, unmount,
and remount delegations cannot be supported with the existing code. It
may be possible to add this functionality in the future.
This functionality was validated with the cli_user and delegation test
cases from the ZFS Test Suite. These tests exhaustively verify each
of the supported permissions which can be delegated and ensures only
an authorized user can perform it.
Two minor bug fixes were required for test-running.py. First, the
Timer() object cannot be safely created in a `try:` block when there
is an unconditional `finally` block which references it. Second,
when running as a normal user also check for scripts using the
both the .ksh and .sh suffixes.
Finally, existing users who are simulating delegations by setting
group permissions on the /dev/zfs device should revert that
customization when updating to a version with this change.

When ZFS partitions a block device it must wait for udev to create
both a device node and all the device symlinks. This process takes
a variable length of time and depends on factors such how many links
must be created, the complexity of the rules, etc. Complicating
the situation further it is not uncommon for udev to create and
then remove a link multiple times while processing the udev rules.
Given the above, the existing scheme of waiting for an expected
partition to appear by name isn't 100% reliable. At this point
udev may still remove and recreate think link resulting in the
kernel modules being unable to open the device.
In order to address this the zpool_label_disk_wait() function
has been updated to use libudev. Until the registered system
device acknowledges that it in fully initialized the function
will wait. Once fully initialized all device links are checked
and allowed to settle for 50ms. This makes it far more likely
that all the device nodes will exist when the kernel modules
need to open them.
For systems without libudev an alternate zpool_label_disk_wait()
was updated to include a settle time. In addition, the kernel
modules were updated to include retry logic for this ENOENT case.
Due to the improved checks in the utilities it is unlikely this
logic will be invoked. However, if the rare event it is needed
it will prevent a failure.

When partitioning a device a name may be specified for each partition.
Internally zfs doesn't use this partition name for anything so it
has always just been set to "zfs".
However this isn't optimal because udev will create symlinks using
this name in /dev/disk/by-partlabel/. If the name isn't unique
then all the links cannot be created.
Therefore a random 64-bit value has been added to the partition
label, i.e "zfs-1234567890abcdef". Additional information could
be encoded here but since partitions may be reused that might
result in confusion and it was decided against.

When checking a whole disk to see if it can be safely added to
the pool a variety of checks are done. One of those checks is
to attempt to determine the partition information and scan all
the partitions for existing filesystems.
Since ZoL contains a EFI library this partition scanning is
easy to do for GPT partitioned disks. However, for non-GPT
partitioned disks (MBR/EBR) things are a bit harder. The lack of
a convenient library means non-GPT partitioned disks will not
have all their partitions checked. For this reason, the default
behavior was to require the force option. For example:
invalid vdev specification
use '-f' to override the following errors:
/dev/vdb does not contain an GPT label but it may contain partition
information in the MBR.
However in practice requiring the force option for this case is
counter-intuitively less safe. The reason is because only the first
error is returned. By passing the force option it will suppress
this first warning and potentially others you were not aware of.
Therefore this patch inverts the default behavior for non-GPT
formated disks (unformatted, MBR/EBR, etc). If no GPT table is
detected and there is no file system detected on the provided
block device. Then it will be assumed that block device is safe
to use.
Longer term it would be nice to see MBR/EBR scanning added to
the utilities. This should be fairly straight forward to do.
However these days it's somewhat less critical because Linux
defaults to GPT partition tables for devices 2TB or larger.

Historically libblkid support was detected as part of configure
and optionally enabled. This was done because at the time support
for detecting ZFS pool vdevs had just be added to libblkid and
those updated packages were not yet part of many distributions.
This is no longer the case and any reasonably current distribution
will ship a version of libblkid which can detect ZFS pool vdevs.
This patch makes libblkid mandatory at build time and libblkid
the preferred method of scanning for ZFS pools. For distributions
which include a modern version of libblkid there is no change in
behavior. Explicitly scanning the default search paths is still
supported and can be enabled with the '-s' command line option.
Additionally making libblkid mandatory means that the 'zpool create'
command can reliably detect if a specified device has an existing
non-ZFS filesystem (ext4, xfs) and print a warning.

When using 'zpool import' to scan for available pools prefer vdev names
which reference vdevs with more valid labels. There should be two labels
at the start of the device and two labels at the end of the device. If
labels are missing then the device has been damaged or is in some other
way incomplete. Preferring names with fully intact labels helps weed out
bad paths and improves the likelihood of being able to import the pool.

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.

Issue #2
zpool_events_next() can be called in blocking mode by specifying a
non-zero value for the "block" parameter. However, the design of
the ZFS Event Daemon (zed) requires additional functionality from
zpool_events_next(). Instead of adding additional arguments to the
function, it makes more sense to use flags that can be bitwise-or'd
together.
This commit replaces the zpool_events_next() int "block" parameter with
an unsigned bitwise "flags" parameter. It also defines ZEVENT_NONE
to specify the default behavior. Since non-blocking mode can be
specified with the existing ZEVENT_NONBLOCK flag, the default behavior
becomes blocking mode. This, in effect, inverts the previous use
of the "block" parameter. Existing callers of zpool_events_next()
have been modified to check for the ZEVENT_NONBLOCK flag.

Due to the very poorly chosen argument name 'cleanup_fd' it was
completely unclear that this file descriptor is used to track the
current cursor location. When the file descriptor is created by
opening ZFS_DEV a private cursor is created in the kernel for the
returned file descriptor. Subsequent calls to zpool_events_next()
and zpool_events_seek() then require the file descriptor as an
argument to reposition the cursor. When the file descriptor is
closed the kernel state tracking the cursor is destroyed.

Issue #2
Originally, users had to handle spa namespace collisions by either
exporting the already imported pool or by specifying a new name for the
pool with a conflicting name. In the case of root pools from virtual
guests, neither approach to collision resolution is reasonable. This is
addressed by extending the new name syntax with a -t option to specify
that the new name is temporary. When specified, this sets an internal
flag that is passed into the kernel to tell it that all label updates
should refer to the name used in the original label. Consequently, the
original pool name will be retained on export.

ZoL commit 1421c89 unintentionally changed the disk format in a forward-
compatible, but not backward compatible way. This was accomplished by
adding an entry to zbookmark_t, which is included in a couple of
on-disk structures. That lead to the creation of pools with incorrect
dsl_scan_phys_t objects that could only be imported by versions of ZoL
containing that commit. Such pools cannot be imported by other versions
of ZFS or past versions of ZoL.
The additional field has been removed by the previous commit. However,
affected pools must be imported and scrubbed using a version of ZoL with
this commit applied. This will return the pools to a state in which they
may be imported by other implementations.
The 'zpool import' or 'zpool status' command can be used to determine if
a pool is impacted. A message similar to one of the following means your
pool must be scrubbed to restore compatibility.
$ zpool import
pool: zol-0.6.2-173
id: 1165955789558693437
state: ONLINE
status: Errata #1 detected.
action: The pool can be imported using its name or numeric identifier,
however there is a compatibility issue which should be corrected
by running 'zpool scrub'
see: http://zfsonlinux.org/msg/ZFS-8000-ER
config:
...
$ zpool status
pool: zol-0.6.2-173
state: ONLINE
scan: pool compatibility issue detected.
see: https://github.com/zfsonlinux/zfs/issues/2094
action: To correct the issue run 'zpool scrub'.
config:
...
If there was an async destroy in progress 'zpool import' will prevent
the pool from being imported. Further advice on how to proceed will be
provided by the error message as follows.
$ zpool import
pool: zol-0.6.2-173
id: 1165955789558693437
state: ONLINE
status: Errata #2 detected.
action: The pool can not be imported with this version of ZFS due to an
active asynchronous destroy. Revert to an earlier version and
allow the destroy to complete before updating.
see: http://zfsonlinux.org/msg/ZFS-8000-ER
config:

Pools affected by the damaged dsl_scan_phys_t can be detected prior to
an upgrade by running the following command as root:
zdb -dddd poolname 1 | grep -P '^\t\tscan = ' | sed -e 's;scan = ;;' | wc -w
Note that `poolname` must be replaced with the name of the pool you wish
to check. A value of 25 indicates the dsl_scan_phys_t has been damaged.
A value of 24 indicates that the dsl_scan_phys_t is normal. A value of 0
indicates that there has never been a scrub run on the pool.
The regression caused by the change to zbookmark_t never made it into a
tagged release, Gentoo backports, Ubuntu, Debian, Fedora, or EPEL
stable respositorys. Only those using the HEAD version directly from
Github after the 0.6.2 but before the 0.6.3 tag are affected.
This patch does have one limitation that should be mentioned. It will not
detect errata #2 on a pool unless errata #1 is also present. It expected
this will not be a significant problem because pools impacted by errata #2
have a high probably of being impacted by errata #1.
End users can ensure they do no hit this unlikely case by waiting for all
asynchronous destroy operations to complete before updating ZoL. The
presence of any background destroys on any imported pools can be checked
by running `zpool get freeing` as root. This will display a non-zero
value for any pool with an active asynchronous destroy.
Lastly, it is expected that no user data has been lost as a result of
this erratum.

Issue #2094
From time to time it may be necessary to inform the pool administrator
about an errata which impacts their pool. These errata will by shown
to the administrator through the 'zpool status' and 'zpool import'
output as appropriate. The errata must clearly describe the issue
detected, how the pool is impacted, and what action should be taken
to resolve the situation. Additional information for each errata will
be provided at http://zfsonlinux.org/msg/ZFS-8000-ER.
To accomplish the above this patch adds the required infrastructure to
allow the kernel modules to notify the utilities that an errata has
been detected. This is done through the ZPOOL_CONFIG_ERRATA uint64_t
which has been added to the pool configuration nvlist.
To add a new errata the following changes must be made:
* A new errata identifier must be assigned by adding a new enum value
to the zpool_errata_t type. New enums must be added to the end to
preserve the existing ordering.
* Code must be added to detect the issue. This does not strictly
need to be done at pool import time but doing so will make the
errata visible in 'zpool import' as well as 'zpool status'. Once
detected the spa->spa_errata member should be set to the new enum.
* If possible code should be added to clear the spa->spa_errata member
once the errata has been resolved.
* The show_import() and status_callback() functions must be updated
to include an informational message describing the errata. This
should include an action message describing what an administrator
should do to address the errata.
* The documentation at http://zfsonlinux.org/msg/ZFS-8000-ER must be
updated to describe the errata. This space can be used to provide
as much additional information as needed to fully describe the errata.
A link to this documentation will be automatically generated in the
output of 'zpool import' and 'zpool status'.

31fc19399e incorrectly removed $(LIBBLKID)
from cmd/zpool/Makefile.am. This meant that the toolchain was not given
-lblkid, which resulted in the following build failure on Ubuntu 13.10:
/usr/bin/ld: zpool_vdev.o: undefined reference to symbol
'blkid_put_cache@@BLKID_1.0'
/lib/x86_64-linux-gnu/libblkid.so.1: error adding symbols: DSO missing

collect2: error: ld returned 1 exit status
That commit reworked various Makefile.am to follow best practices, so we
reintroduce $(LIBBLKID) in a manner consistent with that, rather than
explicitly reverting the change.
Reproduction of this issue was done on a Gentoo Linux system by
executing the following commands:
zfs create -o mountpoint=/mnt/ubuntu-13.10 rpool/ROOT/ubuntu-13.10
debootstrap --variant=buildd --arch amd64 saucy /mnt/ubuntu-13.10 http://archive.ubuntu.com/ubuntu/
mount -o bind /dev /mnt/ubuntu-13.10/dev/
mount -o bind /proc/ /mnt/ubuntu-13.10/proc/
mount -o bind /sys/ /mnt/ubuntu-13.10/sys/
cp /etc/resolv.conf /mnt/ubuntu-13.10/etc/
(cd /mnt/ubuntu-13.10/root/ && git clone git://github.com/zfsonlinux/zfs.git)
chroot /mnt/ubuntu-13.10/
apt-get install git autoconf libtool zlib1g-dev uuid-dev libblkid-dev
\#apt-get install alien fakeroot vim
cd /root/zfs
./autogen.sh
./configure --with-config=user --prefix=/usr
make
That will create a Ubuntu 13.10 chroot, fetch the sources and build
test. At this point, cmd/zpool/Makefile.am was modified and the
following commands were run to verify that the build issue was resolved:
git clean -xdf
./autogen.sh

Although it is not shown here, the absence of libblkid-dev enables ZFS
to build successfully without the patch. This could explain how this
escaped detection until recently. A test without libblkid-dev was done
to verify that the patch did not cause a regression in the absence of
libblkid:
apt-get remove libblkid-dev
git clean -xdf
./autogen.sh
./configure --with-config=user --prefix=/usr
make
Additionally, the commands themselves were tested against my live system
from within the chroot to ensure basic functionality. My live system had
corresponding kernel modules already installed and basic commands such
as `zpool list` and `zfs list` worked without incident. Lastly, this
patch was also build tested on Gentoo Linux, where it caused no
problems.
At time of writing, these steps can be used to reproduce these results
on any modern Linux system that has debootstrap installed. On Gentoo,
installing debootstrap can be done with `emerge dev-util/debootstrap`.
The current ZFSOnLinux HEAD revision as of writing is
fd23720ae1. Once this is fixed in HEAD,
either that revision or another before this fix and after
31fc19399e will be needed to reproduce
this issue.
Lastly, it remains to be seen why the toolchains on the systems
performing regression tests did not catch this. This is not a
ZFS-specific issue, but it is something that we will want to explore in
the future.

The vast majority of these changes are in Linux specific code.
They are the result of not having an automated style checker to
validate the code when it was originally written. Others were
caused when the common code was slightly adjusted for Linux.
This patch contains no functional changes. It only refreshes
the code to conform to style guide.
Everyone submitting patches for inclusion upstream should now
run 'make checkstyle' and resolve any warning prior to opening

When creating a new pool, or adding/replacing a disk in an existing
pool, partition tables will be automatically created on the devices.
Under normal circumstances it will take less than a second for udev
to create the expected device files under /dev/. However, it has
been observed that if the system is doing heavy IO concurrently udev
may take far longer. If you also throw in some cheap dodgy hardware
it may take even longer.
To prevent zpool commands from failing due to this the default wait
time for udev is being increased to 30 seconds. This will have no
impact on normal usage, the increase timeout should only be noticed
if your udev rules are incorrectly configured.

Libraries that depend on other libraries should list them in ELF's
DT_NEEDED field so that programs linking to them do not need to specify
those libraries unless they depend on them as well. This is not the case
in the current code and the consequence is that anything that needs a
library must know its dependencies. This is fragile and caused GRUB2's
configure script to break when a dependency was added on libblkid in
libzfs.
This resolves that problem by using LIBADD/LDADD to specify libraries in
Makefile.am instead of LDFLAGS. This ensures that proper DT_NEEDED
entries are generated and prevents GRUB2's configure script from
breaking in the presence of a libblkid dependency. This also removes
unneeded dependencies from various files.

WARNING: This patch changes the user/kernel ABI. That means that
the zfs/zpool utilities built from master are NOT compatible with
the 0.6.2 kernel modules. Ensure you load the matching kernel
modules from master after updating the utilities. Otherwise the
zfs/zpool commands will be unable to interact with your pool and
you will see errors similar to the following:
$ zpool list

$ zfs list

Add zvol minor device creation to the new zfs_snapshot_nvl function.
Remove the logging of the "release" operation in
dsl_dataset_user_release_sync(). The logging caused a null dereference
because ds->ds_dir is zeroed in dsl_dataset_destroy_sync() and the

function. I've got no idea why this particular code would have worked
in Illumos. This code has subsequently been completely reworked in
Illumos commit 3b2aab1 (3464 zfs synctask code needs restructuring).

Add a missing call to fnvlist_free(nvl) in log_internal() that was added
in Illumos to fix issue 3085 but couldn't be ported to ZoL at the time

This implements vdev_bdev_database_check(). It alters the detected
sector size of any device listed in a database of drives known to lie
about their physical sector sizes.
This is based on "6931570 Add flash devices' VID/PID to disk table to
advertising 4K physical sector size" from Open Solaris and on
sg_simple4.c from sg3_utils. About two dozen lines are taken from
sg_simple4.c, which is GPLv2 licensed. However, sg_simple4.c is
analogous to a Hello World program and is safe for us to use. We
requested that Douglas Gilbert, the author of sg_simple4.c, confirm that
this is the case. A cutdown version of his response is as follows:
```
I would consider a SCSI INQUIRY example using the Linux sg
driver interface (also written by me) as the equivalent of an
"hello world" program in C.
```
The database was created with the help of the freenode and ZFSOnLinux
communities.
Some notes:
1. The following drives both were confirmed to lie via reports in IRC
and they contain capacity information in their identifiers:
INTEL SSDSA2M080
INTEL SSDSA2M160
M4-CT256M4SSD2
WDC WD15EARS-00S
WDC WD15EARS-00Z
WDC WD20EARS-00M
The identifiers for different capacity models were extrapolated and
added under the assumption that those models also lie. Google was used
to verify that the extrapolated drive identifiers existed prior to their
inclusion.
2. The OCZ-VERTEX2 3.5 identifer applies to two drives that differ
solely in page size (and slightly in capacity). One uses 4096-byte pages
and the other uses 8192-byte pages. Both are set to use 8192-byte pages.
We could detect the page size by checking the capacity, but that would
unnecessarily complicate the code.
3. It is possible for updated drive firmware to correctly report the
sector size. There were reports of a few advanced format drives doing
that. One report stated that the vendor changed the identification
string while another was unclear on this. Both reports involved WDC
models.
4. Google was used to determine the size of pages in the listed flash
devices. Reports of 8192-byte pages took precedence over reports of
4096-byte pages.
5. Devices behind USB adapters can have their identification strings
altered. Identification strings obtained across USB adapters are
omitted and no attempt is made to correct for alterations made by USB
adapters when doing comparisons against the database. Two entries in the
Open Solaris database that appear to have been altered by a USB
adapter were omitted.

The vdev_file.c implementation in this patch diverges significantly
from the upstream version. For consistenty with the vdev_disk.c
code the upstream version leverages the Illumos bio interfaces.
This makes sense for Illumos but not for ZoL for two reasons.
1) The vdev_disk.c code in ZoL has been rewritten to use the
Linux block device interfaces which differ significantly
from those in Illumos. Therefore, updating the vdev_file.c
to use the Illumos interfaces doesn't get you consistency
with vdev_disk.c.
2) Using the upstream patch as is would requiring implementing
compatibility code for those Solaris block device interfaces
in user and kernel space. That additional complexity could
lead to confusion and doesn't buy us anything.
For these reasons I've opted to simply move the existing vn_rdwr()
as is in to the taskq function. This has the advantage of being
low risk and easy to understand. Moving the vn_rdwr() function
in to its own taskq thread also neatly avoids the possibility of
a stack overflow.
Finally, because of the additional work which is being handled by
the free taskq the number of threads has been increased. The
thread count under Illumos defaults to 100 but was decreased to 2
in commit 08d08e due to contention. We increase it to 8 until
the contention can be address by porting Illumos #3581.

The issue with hot spares in ZoL is because it opens all leaf
vdevs exclusively (O_EXCL). On Linux, exclusive opens cause
subsequent exclusive opens to fail with EBUSY.
This could be resolved by not opening any of the devices
exclusively, which is what Illumos does, but the additional
protection offered by exclusive opens is desirable. It cleanly
prevents you from accidentally adding an in-use non-ZFS device
to your pool.
To fix this we very slightly relaxed the usage of O_EXCL in
the following ways.
1) Functions which open the device but only read had the
O_EXCL flag removed and were updated to use O_RDONLY.
2) A common holder was added to the vdev disk code. This
allow the ZFS code to internally open the device multiple
times but non-ZFS callers may not.
3) An exception was added to make_disks() for hot spare when
creating partition tables. For hot spare devices which
are already opened exclusively we skip creating the partition
table because this must already have been done when the disk
was originally added as a hot spare.
Additional minor changes include fixing check_in_use() to use
a partition instead of a slice suffix. And is_spare() was moved
above make_disks() to avoid adding a forward reference.

This patch has been slightly modified from the upstream Illumos
version. In the upstream implementation a warning message is
logged to the console. To prevent pointless console noise this
notification is now posted as a "ereport.fs.zfs.vdev.bad_ashift"
event.
The event indicates a non-optimial (but entirely safe) ashift
value was used to create the pool. Depending on your workload
this may impact pool performance. Unfortunately, the only way
to correct the issue is to recreate the pool with a new ashift.
NOTE: The unrelated fix to the comment in zpool_main.c appears

The 'zpool replace' command would fail when given a short name
because unlike on other platforms the short name cannot be
deterministically expanded to a single path. Multiple path
prefixes must be checked and in addition the partition suffix
for whole disks is determined by the prefix.
To handle this complexity a zfs_strcmp_pathname() function was
added which takes either a short or fully qualified device name.
Short names will be expanded using the prefixes in the default
import search path, or the ZPOOL_IMPORT_PATH environment variable
if it's defined. All posible expansions are then compared against
the comparison path. Care is taken to strip redundant slashes to
ensure legitimate matches are not missed.
In the context of this work the existing zfs_resolve_shortname()
function was extended to consider the ZPOOL_IMPORT_PATH when set.
The zfs_append_partition() interface was also simplified to take
only a single buffer.
The vast majority of these changes rework existing Linux specific
code which was originally written to accomidate udev. However,
there is some minimal cleanup which removes Illumos specific code.
This was done to improve readability but the basic flow and intent
of the upstream code was maintained.
These changes are the logical conclusion of the previos work to
adjust the 'zpool import' search behavior, see commit 44867b6a.

The goal of this change is to make 'zpool import' prefer to use
the peristent /dev/mapper or /dev/disk/by-* paths. These are far
preferable to the devices in /dev/ whos names are not persistent
and are determined by the order in which a device is detected.
This patch improves things by changing the default search path from
just to the top level /dev/ directory to (in order):
/dev/disk/by-vdev - Custom rules, use first if they exist
/dev/disk/zpool - Custom rules, use first if they exist
/dev/mapper - Use multipath devices before components
/dev/disk/by-uuid - Single unique entry and persistent
/dev/disk/by-id - May be multiple entries and persistent
/dev/disk/by-path - Encodes physical location and persistent
/dev/disk/by-label - Custom persistent labels
/dev - UNSAFE device names will change
The default search path can be overriden by setting the
ZPOOL_IMPORT_PATH environment variable. This must be a colon
delimited list of paths which are searched for vdevs. If the
'zpool import -d' option is specified only those listed paths
will be searched.
Finally, when multiple paths to the same device are found. If one
of the paths is an exact match for the path used last time to import
the pool it will be used. When there are no exact matches the
prefered path will be determined by the provided search order.
This means you can still import a pool and force specific names by
providing the -d <path> option. And the prefered names will persist
as long as those paths exist on your system.
