[PATCH 0/8] fstests: btrfs: fix test failure when running with compression or nodatasum

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

Several tests fail when running with the compression or nodatasum mount
options. This patchset fixes that by either skipping the tests when those
mount options are present or adapting the tests to able to run.
Details in the changelogs.

Filipe Manana (8):
  btrfs: skip tests incompatible with compression when compression is enabled
  btrfs/290: skip test if we are running with nodatacow mount option
  common/btrfs: add a _require_btrfs_no_nodatasum helper
  btrfs/333: skip the test when running with nodatacow or nodatasum
  btrfs/205: avoid test failure when running with nodatasum mount option
  btrfs: skip tests exercising data corruption and repair when using nodatasum
  btrfs/281: skip test when running with nodatasum mount option
  btrfs: skip tests that exercise compression property when using nodatasum

[PATCH 1/8] btrfs: skip tests incompatible with compression when compression is enabled

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

We have several tests that fail when compression is enabled (MOUNT_OPTIONS
has "-o compress" or "-o compress-force"") because they expect a fixed
extent size and they trigger corruption by writing directly to a device,
therefore making them incompatible with compression.

So add a _require_no_compress call to them.

[PATCH 2/8] btrfs/290: skip test if we are running with nodatacow mount option

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

We exercise corrupting an inline extent and inline extents can't be created
with nodatacow, we get instead a regular file extent item and if we attempt
to corrupt its disk_bytenr field with btrfs-corrupt-block we fail tree-checker
validation at mount time resulting in failure to mount and the following in
dmesg:

[514127.759739] BTRFS critical (device sdc): corrupt leaf: root=5 \
        block=30408704 slot=8 ino=257 file_offset=0, invalid disk_bytenr for \
        file extent, have 7416089308958521981, should be aligned to 4096
[514127.762715] BTRFS error (device sdc): read time tree block corruption \
        detected on logical 30408704 mirror 1

So add a _require_btrfs_no_nodatacow call to the test.

mount option is give, as we do have several tests that fail, for several

[PATCH 4/8] btrfs/333: skip the test when running with nodatacow or nodatasum

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

Encoded writes are reject for inodes with the NODATASUM flag, so we must skip
the test if running with either the nodatasum or nodatacow (which implies
nodatasum) mount options.

So skip the test when under nodatacow and nodatasum mount options.

[PATCH 5/8] btrfs/205: avoid test failure when running with nodatasum mount option

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

Currently the test fails when we pass "-o nodatasum" in MOUNT_OPTIONS and
the reason is because we enable compression, with "chattr +c", on a file
and then try to clone from it to a file with nodatasum inherited from the
mount options, which results in the clone ioctl to fail with -EINVAL since
it's not possible to clone from datasum to nodatasum and vice-versa.

Fix this by removing the "chattr +c", as it's not needed and we already
exercise the compression scenario by explicitly cycle mounting the scratch
device with "-o compress". This also allows us to exercise cloning the
"foo1" file without compression. I originally added the "chattr +c" call
but this was probably an oversight while debugging something.

[PATCH 6/8] btrfs: skip tests exercising data corruption and repair when using nodatasum

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

Several tests exercise corrupting data and then checking that on read the
data is repaired, but this requires using checksums, so the tests fail
when running with the nodatasum mount option.

So add a _require_btrfs_no_nodatasum call to these tests.

[PATCH 7/8] btrfs/281: skip test when running with nodatasum mount option

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

The test exercises compression and compression doesn't happen on inodes
with checksums disabled (nodatasum), making the test fail the expectations
if getting compressed extents. So skip the test if nodatasum is present.

[PATCH 8/8] btrfs: skip tests that exercise compression property when using nodatasum

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

A couple tests exercise the compression property and that fails when an
inode has the nodatasum flag set. So skip the tests when running under the
nodatasum mount option.

[PATCH v2 0/8] fstests: btrfs: fix test failures when running with compression or nodatasum

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

Several tests fail when running with the compression or nodatasum mount
options. This patchset fixes that by either skipping the tests when those
mount options are present or adapting the tests to able to run.
Details in the changelogs.

V2: Updated patch 5/8, the chattr must stay as we really want to create
    an inline compressed extent, otherwise it wouldn't be exercising
    cloning of an inline extent. So skip the test instead of nodatasum
    is present and add a comment about it.

    Added some collect review tags.

[PATCH v2 1/8] btrfs: skip tests incompatible with compression when compression is enabled

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

We have several tests that fail when compression is enabled (MOUNT_OPTIONS
has "-o compress" or "-o compress-force"") because they expect a fixed
extent size and they trigger corruption by writing directly to a device,
therefore making them incompatible with compression.

So add a _require_no_compress call to them.

[PATCH v2 2/8] btrfs/290: skip test if we are running with nodatacow mount option

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

We exercise corrupting an inline extent and inline extents can't be created
with nodatacow, we get instead a regular file extent item and if we attempt
to corrupt its disk_bytenr field with btrfs-corrupt-block we fail tree-checker
validation at mount time resulting in failure to mount and the following in
dmesg:

[514127.759739] BTRFS critical (device sdc): corrupt leaf: root=5 \
        block=30408704 slot=8 ino=257 file_offset=0, invalid disk_bytenr for \
        file extent, have 7416089308958521981, should be aligned to 4096
[514127.762715] BTRFS error (device sdc): read time tree block corruption \
        detected on logical 30408704 mirror 1

So add a _require_btrfs_no_nodatacow call to the test.

From: Filipe Manana <fdmanana@suse.com>

Currently the test fails when we pass "-o nodatasum" in MOUNT_OPTIONS and
the reason is because we enable compression, with "chattr +c", on a file
and then try to clone from it to a file with nodatasum inherited from the
mount options, which results in the clone ioctl to fail with -EINVAL since
it's not possible to clone from datasum to nodatasum and vice-versa.

So skip the test if nodatasum is a mount option.

[PATCH v2 7/8] btrfs/281: skip test when running with nodatasum mount option

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

The test exercises compression and compression doesn't happen on inodes
with checksums disabled (nodatasum), making the test fail the expectations
if getting compressed extents. So skip the test if nodatasum is present.

[PATCH v2 8/8] btrfs: skip tests that exercise compression property when using nodatasum

[fdmanana]

From: Filipe Manana <fdmanana@suse.com>

A couple tests exercise the compression property and that fails when an
inode has the nodatasum flag set. So skip the tests when running under the
nodatasum mount option.
