fstests: Add more sanity to seek_sanity_test
seek_sanity_test checks for one of several SEEK_DATA/HOLE
behaviors and allows for the default behavior of filesystems,
where SEEK_HOLE always returns EOF.
This means that if filesystem has a regression in finding
holes, the sanity test won't catch it. And indeed this regression
happened in overlayfs on kernel v4.19 and went unnoticed.
To improve test coverage, add a flag -f to seek_sanity_test to
indicate that the default behavior is not acceptable.
Whitelist all filesystem types that are expected to detect holes
and use wrapper when invoking seek_sanity_test to add the -f flag
to those filesystems.
Overlayfs inherits expected behavior from base fs type.

Some btrfs test cases use btrfs module-reload to unregister devices
in the btrfs kernel. The problem with the module-reload approach is,
if test system contains btrfs as rootfs, then you can't run these
test cases.
Patches [1] introduced btrfs forget feature which can unregister
devices without the module-reload approach.
[1]
btrfs-progs: device scan: add new option to forget one or all scanned devices
btrfs: introduce new ioctl to unregister a btrfs device
And this patch makes relevant changes in the fstests to use this new
feature, when available.
We have a known bug in btrfs, that we let the device path be changed
after the device has been mounted. So using this loop hole the new
copied device would appears as if its mounted immediately after its
been copied. So this test case reproduces this issue.
For example:
Initially.. /dev/mmcblk0p4 is mounted as /
lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mmcblk0 179:0 0 29.2G 0 disk
|-mmcblk0p4 179:4 0 4G 0 part /
|-mmcblk0p2 179:2 0 500M 0 part /boot
|-mmcblk0p3 179:3 0 256M 0 part [SWAP]
`-mmcblk0p1 179:1 0 256M 0 part /boot/efi
btrfs fi show
Label: none uuid: 07892354-ddaa-4443-90ea-f76a06accaba
Total devices 1 FS bytes used 1.40GiB
devid 1 size 4.00GiB used 3.00GiB path /dev/mmcblk0p4
Copy mmcblk0 to sda
dd if=/dev/mmcblk0 of=/dev/sda
And immediately after the copy completes the change in the device
superblock is notified which the automount scans using
btrfs device scan and the new device sda becomes the mounted root
device.
lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 14.9G 0 disk
|-sda4 8:4 1 4G 0 part /
|-sda2 8:2 1 500M 0 part
|-sda3 8:3 1 256M 0 part
`-sda1 8:1 1 256M 0 part
mmcblk0 179:0 0 29.2G 0 disk
|-mmcblk0p4 179:4 0 4G 0 part
|-mmcblk0p2 179:2 0 500M 0 part /boot
|-mmcblk0p3 179:3 0 256M 0 part [SWAP]
`-mmcblk0p1 179:1 0 256M 0 part /boot/efi
btrfs fi show /

Total devices 1 FS bytes used 1.40GiB
devid 1 size 4.00GiB used 3.00GiB path /dev/sda4
The bug is quite nasty that you can't either unmount /dev/sda4 or
/dev/mmcblk0p4. And the problem does not get solved until you take
the sda out of the system on to another system to change its fsid using
the 'btrfstune -u' command.

The current XFS code never actually uses those for buffer writes,
but a pending patch changes that. For SEEK_HOLE / SEEK_DATA to work
properly in that case we also need to look at the COW fork in their
implementations and thus have to rely on the unwritten extent page
cache probing. But the tests for it ensure we do have valid data in
the pagecache by calling md5sum on the test files, and thus reading

them all valid data.

Test that after a combination of file renames, linking and creating
a new file with the old name of a renamed file, if we fsync the new
file, after a power failure we are able to mount the filesystem and
all file names correspond to the correct inodes.
This test is motivated by a bug found in btrfs, which is fixed by
applying the following two patches to the linux kernel:
"[PATCH 1/2] Btrfs: fix fsync after succession of renames of different files"
"[PATCH 2/2] Btrfs: fix fsync after succession of renames and unlink/rmdir"
The test passes on ext4, xfs and patched btrfs, however at least in
a 5.0-rc5 linux kernel, it fails on f2fs.

xfs/068: Verify actual file count instead of reported file count
This test has the number of files/dirs created by xfsrestore hardcoded
in golden output.
When fsstress is added new ops, the number of files/dirs created with
the same random seed changes and this regularly breaks this test,
so when new fsstress ops are added they should be either added to the
dump test blacklist or golden output of this test needs to be ammended
to reflect the change.
The golden output includes only the file count reported by xfsrestore
and test does not even verify that this is the correct file count.
Instead, leave the golden output neutral and explicitly verify that
file count before and after the test are the same.
With this change, the test becomes agnostic to fsstress ops and we
could also stop blacklisting clone/dedup/copy ops if we want.
xfs/252: requires fallocate support for preallocation
xfs/252 has a few feature tests, but misses checking for preallocation
support. Because of that it will fail instead of not being run for
and XFS file system in always COW mode.
It generates a pseudorandom 64-bit candidate offset for the
destination file where we'll land the splice data, and then caps the
offset at maxfsize (which is 2^63- 1 on x64), which effectively means
that the data will appear at a very high file offset which creates
large (sparse) files very quickly.
That's not what we want, and some case likes shared/009 will take
forever to run md5sum on lots of huge files.

overlay/061: enhance mmap ro/rw inconsistencies test
overlay/061 is currently the only overlay test that is expected to
fail on upstream kernel.
It is a flavor of test overlay/016 with mread in stead of pread.
The ro/rw inconsistencies related to file read()/write() API were
fixed with stacked file operations in v4.19, but the ro/rw
inconsistencies related to shared mmap read/write remain to be
fixed.
The test currently checks cache coherency between mmap read and file
write(), but this sort of cache coherency is a Linux implementation
detail not a requirement of the API.
Instead of mread vs. pwrite, check consistency of mread vs. mwrite
to shared mmap, which is required by the MMAP_SHARED API.
Because we can, perform the test on shared memory that maps files
that are already close and check also that mwrite after file is
closed is persistent. This adds test coverage for future overlayfs
writeback code.

btrfs: Test if btrfs will commit too many transactions for balance
Kernel commit 64403612b73a ("btrfs: rework
btrfs_check_space_for_delayed_refs") is introducing a regression for
btrfs balance performance.
Since that commit will cause btrfs to commit too many transactions
for nothing during balance/relocation, it will slow balance
dramatically even we only need to relocate several megabytes.
This test case will catch the problem by using super block
generation as failure criteria.
For small chunk relocated, we will commit 6 transactions for each
block group, and the test case should only have 2 block groups, it
should only commit 12 transactions.
This test case will use 120 as the threshold to detect the failure.
And in my test environment, with kernel fix btrfs committed 14
transactions. While without the fix btrfs committed 209
transactions.
So the test case should be enough to detect the regression, while still
keep the runtime small enough for failure.

btrfs: Test if btrfs hits EDQUOT without trying to reclaim some space
Commit a514d63882c3 ("btrfs: qgroup: Commit transaction in advance
to reduce early EDQUOT") is no longer forcing transaction commit to
reclaim space, and only commits transaction asynchronously in
advance to address it.
However the criteria used in async transaction commit is not
comprehensive, thus it doesn't reclaim space automatically.
This test case will check the behavior by:
1) Falloc a large padding file
This file will take 90% of the qgroup limit
2) Sync the fs
To reflect the qgroup changes
3) Delete the file
Qgroup won't reclaim the space until transaction committed.
4) Try to write a file
If kernel not fixed, qgroup will not automatically commit transaction
to reclaim the freed space and hit EDQUOT.
This bug is going to be fixed by a patch for kernel titled:
"btrfs: qgroup: Make qgroup async transaction commit more aggressive".

common/dump: disable splice from FSSTRESS_AVOID
New fsstress operation breaks fs dump/restore testing which use
fsstress, e.g xfs/068.
In _create_dumpdir_stress_num, disable splice in fsstress so that we
dump exactly the same set of files and directories.
Quote Dave's comments for future reference
"
fsstress is just creating regular files differently. It has no
impact on xfsdump does except to change the number of files created
and the directory layout.
If this new functionality were creating a new type of file that
xfsdump has to handle, or adding new attributes or changing the
metadata of the existing files, then we want to make sure xfsdump is
tested against that, and so we'd be changing the golden output after
careful checking that both xfsdump and xfs_restore are working
correctly and the file count is correct.
But when all we are doing is creating normal, regular files just
with a different syscall, it makes no sense to perturb the existing
test then we have to go and validate that the new set of files being
tested is actually scanned correctly, is complete and correct. Using
a blacklist to avoid unnecessary perturbation such as in cases like
this is the right thing to do because we've had to determine if the
new functionality is a useful addition to xfsdump/restore test
coverage or not.

Commit fb235dc06fac ("btrfs: qgroup: Move half of the qgroup

It's going to be fixed by "btrfs: qgroup: Don't trigger backref walk

This test will generate pwrite background workload, along with
constant subvolume creation and deletion to trigger the bug.
It needs some time to generate enough files to bump the tree height
to trigger the bug.
In my test environment, with 'unsafe' cache mode for the VM, it
triggers the bug at around 70~90 seconds. So I leave the default
runtime to 120s to make sure the bug will be triggered.
