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.

Issue #5848Closes#6862
On Linux, ftruncate(2) always changes the file timestamps, even if the
file size is not changed. However, in case of a successfull
truncate(2), the timestamps are updated only if the file size changes.
This translates to the VFS calling the ZFS Posix Layer "setattr"
function (zpl_setattr) with ATTR_MTIME and ATTR_CTIME unconditionally
set on the iattr mask only when doing a ftruncate(2), while the
truncate(2) is left to the filesystem implementation to be dealt with.
This behaviour is consistent with POSIX:2004/SUSv3 specifications
where there's no explicit requirement for file size changes to update
the timestamps only for ftruncate(2):
http://pubs.opengroup.org/onlinepubs/009695399/functions/truncate.htmlhttp://pubs.opengroup.org/onlinepubs/009695399/functions/ftruncate.html
This has been later updated in POSIX:2008/SUSv4 where, for both
truncate(2)/ftruncate(2), there's no mention of this size change
requirement:
http://austingroupbugs.net/view.php?id=489http://pubs.opengroup.org/onlinepubs/9699919799/functions/truncate.htmlhttp://pubs.opengroup.org/onlinepubs/9699919799/functions/ftruncate.html
Unfortunately the Linux VFS is still calling into the ZPL without
ATTR_MTIME/ATTR_CTIME set in the truncate(2) case: we fix this by
explicitly updating the timestamps when detecting the ATTR_SIZE bit,
which is always set in do_truncate(), on the iattr mask.

The only place vn_rename and vn_remove are used is when writing
out an updated pool configuration file. By truncating the file
instead of renaming and removing it we can avoid having to implement
these interfaces entirely. Functionally an empty cache file is
treated the same as a missing cache file. This is particularly
advantageous because the Linux kernel has never provided a way
to reliably implement vn_rename and vn_remove.
The cachefile_004_pos.ksh test case was updated to understand
that an empty cache file is the same as a missing one.
The zfs-import-* systemd service files were not updated to use

Because resuming from a token requires "guid" -> "snapshot" mapping
we have to walk the whole dataset hierarchy to find the right snapshot
to send; when both source and destination exists, for an incremental
resumable stream, libzfs gets confused and picks up the wrong snapshot
to send from: this results in attempting to send
"destination@snap1 -> source@snap2"
instead of
"source@snap1 -> source@snap2"
which fails with a "Invalid cross-device link" error (EXDEV).
Fix this by adjusting the logic behind dataset traversal in

With the addition of the ABD changes consumption of the virtual
address space has been greatly reduced. This exposed an issue on
CONFIG_HIGHMEM systems where free memory was being calculated
incorrectly. Functionally this didn't cause any major problems
prior to ABD because a lack of available virtual address space
was used as an indicator of low memory.
This patch makes the following changes to address the issue and
in the process realigns the code further with OpenZFS. There
are no substantive changes in behavior for 64-bit systems.
* Added CONFIG_HIGHMEM case to the arc_all_memory() and
arc_free_memory() functions to only consider low memory pages
on CONFIG_HIGHMEM systems.
* The arc_free_memory() function was updated to return bytes
instead of pages to be consistent with the other helper
functions. In user space we make up some reasonable values
since currently only testing is performed in this context.
* Adds three new values to the arcstats kstat to provide visibility
in to the ARC's assessment of the memory situation:
memory_all_bytes, memory_free_bytes, and memory_available_bytes.
* Added kmem_reap() call to arc_available_memory() for 32-bit
builds to realign code with OpenZFS.
* Reduced size of test file in /async_destroy_001_pos.ksh to
speed up test case. Multiple txgs are still required.
* Move vdevs used by zpool_clear_001_pos and zpool_upgrade_002_pos

When receiving a FREEOBJECTS record, receive_freeobjects()
incorrectly skips a freed object in some cases. Specifically, this
happens when the first object in the range to be freed doesn't exist,
but the second object does. This leaves an object allocated on disk
on the receiving side which is unallocated on the sending side, which
may cause receiving subsequent incremental streams to fail.
The bug was caused by an incorrect increment of the object index
variable when current object being freed doesn't exist. The
increment is incorrect because incrementing the object index is
handled by a call to dmu_object_next() in the increment portion of
the for loop statement.

Refactor dmu_object_alloc_dnsize() and dnode_hold_impl() to simplify the
code, fix errors introduced by commit dbeb879 (PR #6117) interacting
badly with large dnodes, and improve performance.
* When allocating a new dnode in dmu_object_alloc_dnsize(), update the
percpu object ID for the core's metadnode chunk immediately. This
eliminates most lock contention when taking the hold and creating the
dnode.
* Correct detection of the chunk boundary to work properly with large
dnodes.
* Separate the dmu_hold_impl() code for the FREE case from the code for
the ALLOCATED case to make it easier to read.
* Fully populate the dnode handle array immediately after reading a
block of the metadnode from disk. Subsequently the dnode handle array
provides enough information to determine which dnode slots are in use
and which are free.
* Add several kstats to allow the behavior of the code to be examined.
* Verify dnode packing in large_dnode_008_pos.ksh. Since the test is
purely creates, it should leave very few holes in the metadnode.
* Add test large_dnode_009_pos.ksh, which performs concurrent creates
and deletes, to complement existing test which does only creates.
With the above fixes, there is very little contention in a test of about

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.

* Implemented portable pthread_attr_clone() function.
Finally, update the build system such that libzpool.so is no

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.

When performing concurrent object allocations using the new
multi-threaded allocator and large dnodes it's possible to
allocate overlapping large dnodes.
This case should have been handled by detecting an error
returned by dnode_hold_impl(). But that logic only checked
the returned dnp was not-NULL, and the dnp variable was not
reset to NULL when retrying. Resolve this issue by properly
checking the return value of dnode_hold_impl().
Additionally, it was possible that dnode_hold_impl() would
misreport a dnode as free when it was in fact in use. This
could occurs for two reasons:
* The per-slot zrl_lock must be held over the entire critical
section which includes the alloc/free until the new dnode
is assigned to children_dnodes. Additionally, all of the
zrl_lock's in the range must be held to protect moving
dnodes.
* The dn->dn_ot_type cannot be solely relied upon to check
the type. When allocating a new dnode its type will be
DMU_OT_NONE after dnode_create(). Only latter when
dnode_allocate() is called will it transition to the new
type. This means there's a window when allocating where
it can mistaken for a free dnode.

Without this commit, the mmp thread does not wake up and detect the new

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.

This addition will enable us to sync an open TXG to the main pool
on demand. The functionality is similar to 'sync(2)' but 'zpool sync'
will return when data has hit the main storage instead of potentially
just the ZIL as is the case with the 'sync(2)' cmd.

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

FAULTED state will trigger the FMA code, allowing for things like
autoreplace and triggering the slot fault LED. The -f faults
persist across imports, unless they were set with the temporary

Enable additional test cases, in most cases this required a few
minor modifications to the test scripts. In a few cases a real
bug was uncovered and fixed. And in a handful of cases where pools
are layered on pools the test case will be skipped until this is
supported. Details below for each test case.
* zpool_add_004_pos - Skip test on Linux until adding zvols to pools
is fully supported and deadlock free.
* zpool_add_005_pos.ksh - Skip dumpadm portion of the test which isn't
relevant for Linux. The find_vfstab_dev, find_mnttab_dev, and
save_dump_dev functions were updated accordingly for Linux. Add
O_EXCL to the in-use check to prevent the -f (force) option from
working for mounted filesystems and improve the resulting error.
* zpool_add_006_pos - Update test case such that it doesn't depend
on nested pools. Switch to truncate from mkfile to reduce space
requirements and speed up the test case.
* zpool_clear_001_pos - Speed up test case by filling filesystem to
25% capacity.
* zpool_create_002_pos, zpool_create_004_pos - Use sparse files for
file vdevs in order to avoid increasing the partition size.
* zpool_create_006_pos - 6ba1ce9 allows raidz+mirror configs with
similar redundancy. Updating the valid_args and forced_args cases.
* zpool_create_008_pos - Disable overlapping partition portion.
* 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
known as slice 2, on Illumos. This prevents overwriting the
default TESTPOOL which was causing the failure.
* zpool_import_002_pos, zpool_import_012_pos - No changes needed.
* zpool_remove_003_pos - No changes needed
* 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.
File creation switched from /tmp to /var/tmp. Enabled minimal
useful tests for Linux, skip test cases which aren't applicable.

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
be specified from the command line, if desired.
Finally, fix a bug in add-o_ashift.ksh caused by a missing variable.

When vdev_psize increases, the location of labels 2 and 3 changes
because their location is relative to the end of the device.
The configs for labels 2 and 3 are written during the next spa_sync()
because the vdev is added to the dirty config list. However, the
uberblock rings are not re-written in their new location, leaving the
device vulnerable to the beginning of the device being overwritten or
damaged.
This patch copies the uberblock ring from label 0 to labels 2 and 3,
in their new locations, at the next sync after vdev_psize increases.
Also, add a test zpool_expand_004_pos.ksh to confirm the uberblocks
are copied.

OpenZFS-commit: https://github.com/openzfs/openzfs/commit/5602294Closes#6067
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.

musl's sys/errno.h is literally:
/#warning redirecting incorrect #include <sys/errno.h> to <errno.h>
/#include <errno.h>
It does the same for sys/{poll,signal}.h. This is rather noisy when
building ZoL against musl. musl is also correct in pointing out that the
correct headers are outside of sys/ according to the single unix
specification:
http://pubs.opengroup.org/onlinepubs/7908799/xsh/errno.h.htmlhttp://pubs.opengroup.org/onlinepubs/7908799/xsh/poll.h.htmlhttp://pubs.opengroup.org/onlinepubs/7908799/xsh/signal.h.html
Lets implement our own sys/* versions of these headers to redirect to
the proper userland ones when building in userspace. That will silence
the warning.
There are also some instances where we include incorrectly from sys/ or
from outside of sys/ in userspace only code. In these instances, lets
just fix the includes directly.

- 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.

OpenZFS-commit: https://github.com/openzfs/openzfs/commit/c95076cCloses#5981
When we try assign a new transaction to a TXG we must know beforehand
if there is sufficient free space on disk. This is to decide,
in dmu_tx_assign(), if we should reject the TX with ENOSPC.
We rely on spa_get_worst_case_asize() to inflate the size of our
logical writes by a factor of spa_asize_inflation which is
calculated as:
(VDEV_RAIDZ_MAXPARITY + 1) * SPA_DVAS_PER_BP * 2 == 24
The problem with the current implementation is that we don't take
into account what happens with very small writes on VDEVs with large
physical block sizes.
Consider the case of writes to a dataset with recordsize=512,
copies=3 on a VDEV with ashift=13 (usually SSD with 8K block size):
every logical IO will end up allocating 3 * 8K = 24K on disk, so 512
bytes multiplied by 48, which is double the size we account for.
If we allow this kind of writes to be assigned a TX it is possible,
when the pool is almost full, to trigger an allocation failure
(ENOSPC) in the ZIO pipeline, which will in turn result in the whole
pool being suspended.
The bug is fixed by using, in spa_get_worst_case_asize(), the MAX()
value chosen between the logical io size from zfs_write() and the
maximum physical block size used among our VDEVs.

- Utilities which aren't available under Linux have been removed.
- Because of sudo's default secure path behavior PATH must be
explicitly reset at the top of libtest.shlib. This avoids the
need for all users to customize secure path on their system.
- Updated ZoL infrastructure to manage constrained path
- Updated all test cases
- Check permissions for usergroup tests
- When testing in-tree create links under bin/
- Update fault cleanup such that missing files during
cleanup aren't fatal.
- Configure su environment with constrained path

Automated auto-replace test to go along with ZED FMA integration
(PR 4673) auto-replace_001.pos works using a scsi_debug device
(the only usable virtual device currently due to whole_disk var
needing to be set)
Functionality for automated FMA auto-replace test to work with
scsi_debug devs: Some functionality/exceptions needed to be
added for automation of auto-replace to work correctly.
In the test an alias vdev_id rule is added for any scsi_debug
device which sets the phys_path="scsidebug" after a udevadm
trigger command.
A symlink is created for the vdev_id.conf file (in /etc/zfs/ by
default) to be used in-tree for the test suite
(/var/tmp/zfs/vdev_id.conf). "./scripts/zfs-helpers.sh -i" needs
to be run before fault tests in the ZTS (to use udev rules in-tree)

Issue #5887Closes#5934
For zdb -l, detect when the configuration nvlist in some label l (l>0)
is the same as a configuration already dumped. If so, do not dump it.
Make a similar check when dumping Uberblocks for zdb -lu. Check whether
a label already dumped contains an identical Uberblock. If so, do not
dump the Uberblock.
When dumping a configuration or Uberblock, state which labels it is
found in (0-3), for example: labels = 1 2 3
Detecting redundant uberblocks or configurations is accomplished by
calculating checksums of the uberblocks and the packed nvlists
containing the configuration.
If there is nothing unique to be dumped for a label (ie the
configuration and uberblocks have checksums matching those already
dumped) print nothing for that label.
With additional l's or u's, increase verbosity as follows:
-l Dump each unique configuration only once.
Indicate which labels it appears in.
-ll In addition, dump label space usage stats.
-lll Dump every configuration, unique or not.
-u Dump each unique, valid, uberblock only once.
Indicate which labels it appears in.
-uu In addition, state which slots are invalid.
-uuu Dump every uberblock, unique or not.
-uuuu Dump the uberblock blockpointer (used to be -uuu)
Make exit values conform to the manual page. Failing to unpack a
configuration nvlist is considered an error, as well as failing to open
or read from the device.
Add three tests, zdb_00{3,4,5}_pos to verify the above functionality.

Porting notes:
- The library libdiskmgmt is specific to illumos so these changes
currently have no impact under Linux. This mechanism could be
potentially leveraged in the future.
Use -pH flags in get_pool_prop so that numeric properties such as size
can be compared. The zpool_expand test suite is currently the only one
which uses get_pool_prop for a numeric property.
Add TEMPFILE and TEMPFILE{0,1,2} to default.cfg for tests that must
build pools on top of files, such as this one where expansion is
necessary but the entries in DISKS may not point to entities that can be
expanded.
Base the pool used for testing on file-type VDEVs instead of using zvols
within an underlying pool, to avoid issues that come up when pools are
backed by other pools.
Remove shell variables EX_1GB and EX_2GB used to recognize correct expansion,
and instead calculate the appropriate values based on the variables used to
control file or volume size, org_size and exp_size. This change is also
made in test 001 although that test is not enabled because it depends on
FMA.
Finally, enable zpool_expand_002_pos.

zpool iostat allows you to specify only certain vdevs to display.
Currently, if you run 'zpool iostat -c CMD vdev1 vdev2 ...'
on specific vdevs, it will actually run the command on *all* vdevs,
and just display the results for the vdevs you specify. This patch
corrects the behavior to only run the command on the specified vdevs,

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'
NAME STATE READ WRITE CKSUM
mypool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
mpatha ONLINE 0 0 0 I am /dev/mapper/mpatha, /dev/sdc

ZFS Test Suite Performance Regression Tests
This was pulled into OpenZFS via the compressed arc featureand was
separated out in zfsonlinux as a separate pull request from PR-4768.
It originally came in as QA-4903 in Delphix-OS from John Kennedy.
Expected Usage:
$ DISKS="sdb sdc sdd" zfs-tests.sh -r perf-regression.run
Porting Notes:
1. Added assertions in the setup script to make sure required tools
(fio, mpstat, ...) are present.
2. For the config.json generation in perf.shlib used arcstats and
other binaries instead of dtrace to query the values.
3. For the perf data collection:
- use "zpool iostat -lpvyL" instead of the io.d dtrace script
(currently not collecting zfs_read/write latency stats)
- mpstat and iostat take different arguments
- prefetch_io.sh is a placeholder that uses arcstats instead of
dtrace
4. Build machines require fio, mdadm and sysstat pakage (YMMV).
Future Work:
- Need a way to measure zfs_read and zfs_write latencies per pool.
- Need tools to takes two sets of output and display/graph the
differences
- Bring over additional regression tests from Delphix
When using real devices, specify DISKS="sdb sdc sdd" opposed to
/dev/sdb in zfs-tests.sh - otherwise errors with directory names and
disk names registering as "/dev//dev/sdb" for some tests. The same
goes for mpath: DISK="mpatha mpathad mpathb"
Expected Usage:
$ DISKS="sdb sdc sdd" zfs-tests.sh
SLICE_PREFIX is now set as "p" for a loop device (ie loop0p2) or
"" for a real device (ie sdb2), or either for multipath devices
(ie mpatha1 or mpath1p1) instead of only "p" by default. Note that
kpartx partitioning is not currently supported in this patch
(ie "partx") and may need to be disabled on Debian distributions.
Functions added for determining test directory (/dev or /dev/mapper)
as well as slice prefix are determined and exported mostly in the cfg
file of each test group directory.
Currently zpools cannot be created on whole mpath devices that have
been partitioned. In order to fix this tests have either been revised
to use a partition instead, or if there is a size constraint and the
pool needs to be created on the whole disk, partitions are then deleted
if the device is a multipath device. This functionality is added to
default_cleanup() or to individual cleanup scripts if a non-default
cleanup method is used.
The max partitions is currently set at 8 to account for all of the
tests thus far.
Patch changes are generally encompassed in "if is_linux" construct.

Issues:
Under Linux, when executing zfs_destroy_004.ksh destroy $fs is an
error. The key issue here is that illumos kernel treats this case
differently than the Linux kernel. On illumos you can unmount and
destroy a filesystem which is busy and all consumers of it get EIO.
On Linux the expected behavior is to prevent the unmount and destroy.
Cause analysis:
When create $fs file system and mount file system to $mntp.
cd $mntp, linux isn't allow to destroy $fs in this mount contents.
No matter what destroy with parameters.
Solution:
So log_mustnot $ZFS destroy $fs is ok.
cd $olddir and destroy $fs.

Justification
-------------
This feature adds support for variable length dnodes. Our motivation is
to eliminate the overhead associated with using spill blocks. Spill
blocks are used to store system attribute data (i.e. file metadata) that
does not fit in the dnode's bonus buffer. By allowing a larger bonus
buffer area the use of a spill block can be avoided. Spill blocks
potentially incur an additional read I/O for every dnode in a dnode
block. As a worst case example, reading 32 dnodes from a 16k dnode block
and all of the spill blocks could issue 33 separate reads. Now suppose
those dnodes have size 1024 and therefore don't need spill blocks. Then
the worst case number of blocks read is reduced to from 33 to two--one
per dnode block. In practice spill blocks may tend to be co-located on
disk with the dnode blocks so the reduction in I/O would not be this
drastic. In a badly fragmented pool, however, the improvement could be
significant.
ZFS-on-Linux systems that make heavy use of extended attributes would
benefit from this feature. In particular, ZFS-on-Linux supports the
xattr=sa dataset property which allows file extended attribute data
to be stored in the dnode bonus buffer as an alternative to the
traditional directory-based format. Workloads such as SELinux and the
Lustre distributed filesystem often store enough xattr data to force
spill bocks when xattr=sa is in effect. Large dnodes may therefore
provide a performance benefit to such systems.
Other use cases that may benefit from this feature include files with
large ACLs and symbolic links with long target names. Furthermore,
this feature may be desirable on other platforms in case future
applications or features are developed that could make use of a
larger bonus buffer area.
Implementation
--------------
The size of a dnode may be a multiple of 512 bytes up to the size of
a dnode block (currently 16384 bytes). A dn_extra_slots field was
added to the current on-disk dnode_phys_t structure to describe the
size of the physical dnode on disk. The 8 bits for this field were
taken from the zero filled dn_pad2 field. The field represents how
many "extra" dnode_phys_t slots a dnode consumes in its dnode block.
This convention results in a value of 0 for 512 byte dnodes which
preserves on-disk format compatibility with older software.
Similarly, the in-memory dnode_t structure has a new dn_num_slots field
to represent the total number of dnode_phys_t slots consumed on disk.
Thus dn->dn_num_slots is 1 greater than the corresponding
dnp->dn_extra_slots. This difference in convention was adopted
because, unlike on-disk structures, backward compatibility is not a
concern for in-memory objects, so we used a more natural way to
represent size for a dnode_t.
The default size for newly created dnodes is determined by the value of
a new "dnodesize" dataset property. By default the property is set to
"legacy" which is compatible with older software. Setting the property
to "auto" will allow the filesystem to choose the most suitable dnode
size. Currently this just sets the default dnode size to 1k, but future
code improvements could dynamically choose a size based on observed
workload patterns. Dnodes of varying sizes can coexist within the same
dataset and even within the same dnode block. For example, to enable
automatically-sized dnodes, run
# zfs set dnodesize=auto tank/fish
The user can also specify literal values for the dnodesize property.
These are currently limited to powers of two from 1k to 16k. The
power-of-2 limitation is only for simplicity of the user interface.
Internally the implementation can handle any multiple of 512 up to 16k,
and consumers of the DMU API can specify any legal dnode value.
The size of a new dnode is determined at object allocation time and
stored as a new field in the znode in-memory structure. New DMU
interfaces are added to allow the consumer to specify the dnode size
that a newly allocated object should use. Existing interfaces are
unchanged to avoid having to update every call site and to preserve
compatibility with external consumers such as Lustre. The new
interfaces names are given below. The versions of these functions that
don't take a dnodesize parameter now just call the _dnsize() versions
with a dnodesize of 0, which means use the legacy dnode size.
New DMU interfaces:
dmu_object_alloc_dnsize()
dmu_object_claim_dnsize()
dmu_object_reclaim_dnsize()
New ZAP interfaces:
zap_create_dnsize()
zap_create_norm_dnsize()
zap_create_flags_dnsize()
zap_create_claim_norm_dnsize()
zap_create_link_dnsize()
The constant DN_MAX_BONUSLEN is renamed to DN_OLD_MAX_BONUSLEN. The
spa_maxdnodesize() function should be used to determine the maximum
bonus length for a pool.
These are a few noteworthy changes to key functions:
* The prototype for dnode_hold_impl() now takes a "slots" parameter.
When the DNODE_MUST_BE_FREE flag is set, this parameter is used to
ensure the hole at the specified object offset is large enough to
hold the dnode being created. The slots parameter is also used
to ensure a dnode does not span multiple dnode blocks. In both of
these cases, if a failure occurs, ENOSPC is returned. Keep in mind,
these failure cases are only possible when using DNODE_MUST_BE_FREE.
If the DNODE_MUST_BE_ALLOCATED flag is set, "slots" must be 0.
dnode_hold_impl() will check if the requested dnode is already
consumed as an extra dnode slot by an large dnode, in which case
it returns ENOENT.
* The function dmu_object_alloc() advances to the next dnode block
if dnode_hold_impl() returns an error for a requested object.
This is because the beginning of the next dnode block is the only
location it can safely assume to either be a hole or a valid
starting point for a dnode.
* dnode_next_offset_level() and other functions that iterate
through dnode blocks may no longer use a simple array indexing
scheme. These now use the current dnode's dn_num_slots field to
advance to the next dnode in the block. This is to ensure we
properly skip the current dnode's bonus area and don't interpret it
as a valid dnode.
zdb
---
The zdb command was updated to display a dnode's size under the
"dnsize" column when the object is dumped.
For ZIL create log records, zdb will now display the slot count for
the object.
ztest
-----
Ztest chooses a random dnodesize for every newly created object. The
random distribution is more heavily weighted toward small dnodes to
better simulate real-world datasets.
Unused bonus buffer space is filled with non-zero values computed from
the object number, dataset id, offset, and generation number. This
helps ensure that the dnode traversal code properly skips the interior
regions of large dnodes, and that these interior regions are not
overwritten by data belonging to other dnodes. A new test visits each
object in a dataset. It verifies that the actual dnode size matches what
was stored in the ztest block tag when it was created. It also verifies
that the unused bonus buffer space is filled with the expected data
patterns.
ZFS Test Suite
--------------
Added six new large dnode-specific tests, and integrated the dnodesize
property into existing tests for zfs allow and send/recv.
Send/Receive
------------
ZFS send streams for datasets containing large dnodes cannot be received
on pools that don't support the large_dnode feature. A send stream with
large dnodes sets a DMU_BACKUP_FEATURE_LARGE_DNODE flag which will be
unrecognized by an incompatible receiving pool so that the zfs receive
will fail gracefully.
While not implemented here, it may be possible to generate a
backward-compatible send stream from a dataset containing large
dnodes. The implementation may be tricky, however, because the send
object record for a large dnode would need to be resized to a 512
byte dnode, possibly kicking in a spill block in the process. This
means we would need to construct a new SA layout and possibly
register it in the SA layout object. The SA layout is normally just
sent as an ordinary object record. But if we are constructing new
layouts while generating the send stream we'd have to build the SA
layout object dynamically and send it at the end of the stream.
For sending and receiving between pools that do support large dnodes,
the drr_object send record type is extended with a new field to store
the dnode slot count. This field was repurposed from unused padding
in the structure.
ZIL Replay
----------
The dnode slot count is stored in the uppermost 8 bits of the lr_foid
field. The bits were unused as the object id is currently capped at
48 bits.
Resizing Dnodes
---------------
It should be possible to resize a dnode when it is dirtied if the
current dnodesize dataset property differs from the dnode's size, but
this functionality is not currently implemented. Clearly a dnode can
only grow if there are sufficient contiguous unused slots in the
dnode block, but it should always be possible to shrink a dnode.
Growing dnodes may be useful to reduce fragmentation in a pool with
many spill blocks in use. Shrinking dnodes may be useful to allow
sending a dataset to a pool that doesn't support the large_dnode
feature.
Feature Reference Counting
--------------------------
The reference count for the large_dnode pool feature tracks the
number of datasets that have ever contained a dnode of size larger
than 512 bytes. The first time a large dnode is created in a dataset
the dataset is converted to an extensible dataset. This is a one-way
operation and the only way to decrement the feature count is to
destroy the dataset, even if the dataset no longer contains any large
dnodes. The complexity of reference counting on a per-dnode basis was
too high, so we chose to track it on a per-dataset basis similarly to
the large_block feature.

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.
