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.

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.

illumos code doesn't check for feature_get_refcount() returning
ENOTSUP (which means feature is disabled) in zdb. zfsonlinux added
a check in https://github.com/zfsonlinux/zfs/commit/784652c
due to #3468. The check was reintroduced here.

Build products from an out of tree build should be written
relative to the build directory. Sources should be referred
to by their locations in the source directory.
This is accomplished by adding the 'src' and 'obj' variables
for the module Makefile.am, using relative paths to reference
source files, and by setting VPATH when source files are not
co-located with the Makefile. This enables the following:
$ mkdir build
$ cd build
$ ../configure \
--with-spl=$HOME/src/git/spl/ \
--with-spl-obj=$HOME/src/git/spl/build
$ make -s
This change also has the advantage of resolving the following
warning which is generated by modern versions of automake.
Makefile.am:00: warning: source file 'xxx' is in a subdirectory,
Makefile.am:00: but option 'subdir-objects' is disabled

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.

This pool was previously imported into a system with a different hostid,

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.

Issue #2
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.

few variable names and clarifies the documentation.

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.

Closes#2189
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'.

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
./configure --with-config=user --prefix=/usr
make
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
a pull request. The automated builders have been updated to
fail a build if when 'make checkstyle' detects an issue.

Notes:
1. The entries for the Intel DC S3500 were extrapolated from the 800GB
model's entry, which is "ATA INTEL SSDSC2BB80".
2. The entires for the Intel 710 were extrapolated from the 120GG
model's entry, which is "ATA INTEL SSDSA2BZ12".
3. The entires for the Intel 510 were extrapolated from the 250GB
model's entry, which is "ATA INTEL SSDSC2MH25".
4. The entires for the Apple MacBookPro10,1 SSD were extrapolated from
the 512GB model's entry, which is "ATA APPLE SSD SM512E". Google
searches suggest that this is a rebadged Samsung 830.
5. The entires for the Apple MacBookAir3,1 SSD were extrapolated from
the 128GB model's entry, which is "ATA APPLE SSD TS128C". Google
searches suggest that this is a rebadged Kingston SSDNow V+ 100 (based
on Toshiba).
6. Sun Comstar is an iSCSI Target, so we cannot tell what the correct
sector size is through this method. We list it only for reference
purposes, but it is commented out. Similarly, it is not clear what the
right thing to do for Netapp is, so we comment it out.

On some platforms symbols provided by libzfs_core and used by
libzfs were not available to the linker. To avoid this issue
libzfs_core has been added to the list of required libraries
when building utilities which depend on libzfs. This should
have been handled properly by libtool and it's still not
entirely clear why it wasn't on all platforms.

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.

Porting notes:
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
failed to read pool configuration: bad address
no pools available
$ zfs list
no datasets available
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
logging functions try to get the ds name via the dsl_dataset_name()
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).
Squash some "may be used uninitialized" warning/erorrs.
Fix some printf format warnings for %lld and %llu.
Apply a few spa_writeable() changes that were made to Illumos in
illumos/illumos-gate.git@cd1c8b8 as part of the 3112, 3113, 3114 and
3115 fixes.
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
(zfsonlinux/zfs@9e11c73) because it depended on future work.
