overlay: add test for lowerdir mount option parsing
Check parsing and display of spaces and escaped colons and commans in

This is a regression test for two bugs introduced in v6.5 with the

There is another regression of new mount api related to libmount parsing
of escaped commas, but this needs a fix in libmount - this test only
verifies the fixes in the kernel, so it uses LIBMOUNT_FORCE_MOUNT2=always

The count of failure messages is the same as the count as the "-l 4k"
fstrim invocations. Since this is an 8k-block filesystem, the -l
parameter is clearly incorrect. The test computes random -m and -l
options.
Therefore, create helper functions to guess at the minimum and maximum
length and minlen parameters that can be used with the fstrim program.
In the inner loop of the test, make sure that our choices for -m and -l
fall within those constraints.

generic/465: only complain about stale disk contents when racing directio
This test does a strange thing with directio -- it races a reader thread
with an appending aio writer thread and checks that the reader thread
only ever sees a (probably short) buffer containing the same contents
that are being read.
However, this has never worked correctly on XFS, which supports
concurrent readers and writers for directio. Say you already have a
file with a single written mapping A:
This implies separate bios for b and c. Both bios are issued, but c
completes first. The ioend for c will extend i_size all the way to
new_EOF. Extent b is still marked unwritten because it hasn't completed
yet.
Next, the test reader slips in and tries to read the range between the
old EOF and the new EOF. The file looks like this now:
So the reader sees "bbbbCCCCC" in the mapping, and the buffer returned
contains a range of zeroes followed by whatever was written to C.
For pagecache IO I would say that i_size should not be extended until
the extending write is fully complete, but the pagecache also
coordinates access so that reads and writes cannot conflict.
However, this is directio. Reads and writes to the storage device can
be issued and acknowledged in any order. I asked Ted and Jan about this
point, and they echoed that for directio it's expected that application
software must coordinate access themselves.
In other words, the only thing that the reader can check here is that
the filesystem is not returning stale disk contents. Amend the test so
that null bytes in the reader buffer are acceptable.

writing modified primary superblock
sb root inode INO inconsistent with calculated value INO
Eventually I tracked this down to a mis-interaction between the test,
xfs_repair, and the storage device.
If the device doesn't support discard, _scratch_mkfs won't zero the
entire disk to remove old dead superblocks that might have been written
by previous tests. After we shatter the primary super, the xfs_repair
scanning code can still trip over those old supers when it goes looking
for secondary supers.
Most of the time it finds the actual AG 1 secondary super, but sometimes
it finds ghosts from previous formats. When that happens, xfs_repair
will talk quite a bit about those failed secondaries, even if it
eventually finds an acceptable secondary sb and completes the repair.
Filter out the messages about secondary supers.

So modify all tests that redirect fsstress' output to /dev/null to instead

This happens because "testdir" and "dira" are not logged on the first fsync
(fsync $SCRATCH_MNT/testdir), but are written as a full commit. That
prevents updating the log on "mv" time, leaving them pre-mv state.
The full commit is induced by the creation of a new block group. On the
zoned mode, we use a dedicated block group for tree-log. That block group
is created on-demand or assigned to a metadata block group if there is
none. On the first mount of a file system, we need to create one because
there is only one metadata block group available for the regular
metadata. That creation of a new block group forces tree-log to be a full
commit on that transaction, which prevents logging "testdir" and "dira".
Fix the issue by calling fsync before the first "sync", which creates the
dedicated block group and let the files be properly logged.

btrfs/237: kick reclaim process with a small filesystem
Since commit 3687fcb0752a ("btrfs: zoned: make auto-reclaim less
aggressive"), the reclaim process won't run unless the 75% (by default) of
the filesystem volume is allocated as block groups. As a result, btrfs/237
won't success when it is run with a large volume.
To run the reclaim process, we need to either fill the FS to the desired
level, or make a small FS so that the test write can go over the level.
Since the current test code expects the FS has only one data block group,
filling the FS is both cumbersome and need effort to rewrite the test code.
So, we take the latter method. We create a small (16 * zone size) FS. The
size is chosen to hold a minimal FS with DUP metadata setup.
However, creating a small FS is not enough. With SINGLE metadata setup, we
allocate 3 zones (one for each DATA, METADATA and SYSTEM), which is less
than 75% of 16 zones. We can tweak the threshold to 51% on regular btrfs
kernel config (!CONFIG_BTRFS_DEBUG), but that is still not enough to start
the reclaim process. So, this test requires CONFIG_BTRFS_DEBUG to set the
threshold to 1%.

+(standard_in) 1: syntax error
+RWF_NOWAIT took seconds
So For async buffered write requests, the request will return -EAGAIN
if the ilock cannot be obtained immediately.
Here also a discussion[1] that seems generic/471 has been broken.
Now, I met this problem in my linux distribution, then I found the above
discussion. IMO, remove this case is ok and then we can avoid to meet this
false report again.
[Additional information from Dave Chinner]
We changed how timestamps are updated so that they are aware of
IOCB_NOWAIT. If the IOCB_NOWIAT DIO write now needs to update the
inode timestamps, it will return -EAGAIN instead of doing
potentially blocking operations that require IO to complete (i.e.
taking a transaction reservation).
Hence the first time we go to do a DIO read an inode, it's going to
do an atime update, which now occurrs from an IOCB_NOWAIT context
and we return -EAGAIN....
Yes, we added non-blocking timestamp updates as part of the async
buffered write support, but this was a general XFS IO path change of
behaviour to address a potential blocking point in *all* IOCB_NOWAIT
reads and writes, buffered or direct.
The test is not validating that RWF_NOWAIT is behaving correctly - it
just was a simple operation that kinda exercised RWF_NOWAIT semantics
when we had no other way to test this code. It has outlived it's
original purpose, so it should be removed...

This is the typical buffer modification during direct IO, which is going
to cause csum mismatch for btrfs, and btrfs properly detects it.
This is the direct cause of the problem.
The root cause is that, io_uring would use signals to handle
submission/completion of IOs.
Thus io_uring operations would interrupt AIO operations, thus causing
the above problem.
[FIX]
To fix the problem, we can just retry io_getevents() so that we can
properly wait for the IO.
This prevents us to modify the IO buffer before writeback really
finishes.
With this fixes, I can no longer reproduce the data corruption.

The filesystem configuration file does not allow you to use symlinks to

real drives do not.
Using a symlink is desirable if you want to enable persistent tests

so to ensure that the same drives are used even after reboot. This
is very useful if you are testing for example with a virtualized

with one or many NVMe drives.
To enable support just add a helper to canonicalize devices prior to

This allows one test runner, kdevops, which I just extended with

symlinks and fallbacks to nvme model + serial symlinks as not all

check: generate gcov code coverage reports at the end of each section
Support collecting kernel code coverage information as reported in
debugfs. At the start of each section, we reset the gcov counters;
during the section wrapup, we'll collect the kernel gcov data.
If lcov is installed and the kernel source code is available, it will
also generate a nice html report. If a CLI web browser is available, it
will also format the html report into text for easy grepping.
This requires the test runner to set REPORT_GCOV=1 explicitly and gcov
to be enabled in the kernel.

btrfs/276: make test accurate regarding number of expected extents
btrfs/276 creates a 16G file with compression enabled in order to quickly
and efficiently create a file with many extents and have a fs tree with a
height of 3 (root node at level 2), so that it can test that fiemap is
correctly reporting extent sharedness when we have shared subtrees of the
fs tree due to a snapshot.
Compression results in extents with a maximum size of 128K and the test
is expecting only extents of 128K, which normally happens if the machine
has a large amount of RAM and writeback is not triggered before the xfs_io
command finishes. However if writeback is triggered in the meanwhile, due
to memory pressure for example, then we can get end up with some extents
that are smaller than 128K, therefore increasing the total number of
extents in the test file and make the test fail.
This seems to happen often on test machines with small amounts of RAM,
such as 4G, as reported by Qu in the following thread:
So to address this create a file with holes and direct IO to make sure we
always get a specific number of extents in the test file. To speedup the
test create 2000 64K extents, with holes in between them, so that it works
on a fs with any sector size, and then create a bunch of files with large
xattrs to quickly bump the fs tree height to 3 for any node size (4K to
64K). This also guarantees that the file extent items are spread over
multiples leaves, in order to exercise fiemap's correctness when reporting
shared extents due to shared subtrees.

fstests: add smoketest group
Darrick suggests that fstests can provide a simple smoketest, by
running several generic filesystem smoke testing for five minutes
apiece (SOAK_DURATION="5m"). Since there are only five smoke tests,
this is effectively a 20min super-quick test.
With gcov enabled, running these tests yields about ~75% coverage for
iomap and ~60% for xfs; or ~50% for ext4 and ~75% for ext4; and ~45%
for btrfs. Coverage was about ~65% for the pagecache.

btrfs: add a test case to make sure scrub can repair parity corruption
There is a kernel regression caused by commit 75b470332965 ("btrfs:
raid56: migrate recovery and scrub recovery path to use error_bitmap"),
which leads to scrub not repairing corrupted parity stripes.
So here we add a test case to verify the P/Q stripe scrub behavior by:
- Create a RAID5 or RAID6 btrfs with minimal amount of devices
This means 2 devices for RAID5, and 3 devices for RAID6.
This would result the parity stripe to be a mirror of the only data
stripe.
And since we have control of the content of data stripes, the content
of the P stripe is also fixed.
- Create an 64K file
The file would cover one data stripe.
- Corrupt the P stripe
- Scrub the fs
If scrub is working, the P stripe would be repaired.
Unfortunately scrub can not report any P/Q corruption, limited by its
reporting structure.
So we can not use the return value of scrub to determine if we
repaired anything.
- Verify the content of the P stripe
- Use "btrfs check --check-data-csum" to double check
By above steps, we can verify if the P stripe is properly fixed.
Commit 3e85dd4fe423 ("misc: add duration for long soak tests") added a
helper executable, soak_duration.awk, is which used by the check
script if SOAK_DURATION is set. This script translates a
"human-friendly" time duration specifier, such as 4m or 2d into an
integer number of seconds. We need to make sure that this script is
installed or the check script will bomb out if SOAK_DURATION is set
(and if the fstests installation doesn't include a full set of fstests
source, but just those files installed by "make install").

btrfs: add a test case to verify that per-fs features directory gets updated
Although btrfs has a per-fs feature directory, it's not properly
refreshed after new features are enabled.
We had some attempts to do that properly, like commit 14e46e04958d
("btrfs: synchronize incompat feature bits with sysfs files").
But unfortunately that commit get later reverted as some call sites is
not safe to update sysfs files.
Now we have a new commit b7625f461da6 ("btrfs: sysfs: update fs features
directory asynchronously") to properly refresh that per-fs features
directory.
So it's time to add a test case for it. The test case itself is pretty
straightforward:
- Make a very basic 3 disks btrfs
Only using the very basic profiles (DUP/SINGLE) so that even older
mkfs.btrfs can support.
- Make sure per-fs features directory doesn't contain "raid1c34" file
- Balance the metadata to RAID1C3 profile
- Verify the per-fs features directory contains "raid1c34" feature file

generic/558: avoid forkbombs on filesystems with many free inodes
Mikulas reported that this test became a forkbomb on his system when he
tested it with bcachefs. Unlike XFS and ext4, which have large inodes
consuming hundreds of bytes, bcachefs has very tiny ones. Therefore, it
reports a large number of free inodes on a freshly mounted 1GB fs (~15
million), which causes this test to try to create 15000 processes.
There's really no reason to do that -- all this test wanted to do was to
exhaust the number of inodes as quickly as possible using all available
CPUs, and then it ran xfs_repair to try to reproduce a bug. Set the
number of subshells to 4x the CPU count and spread the work among them
instead of forking thousands of processes.
