From: Darrick J. Wong <djwong@kernel.org>
It would be useful to be able to run fstests against the userspace
ext[234] driver program fuse2fs. A convention (at least on Debian)
seems to be to install fuse drivers as /sbin/mount.fuse.XXX so that
users can run "mount -t fuse.XXX" to start a fuse driver for a
disk-based filesystem type XXX.
Therefore, we'll adopt the practice of setting FSTYP=fuse.ext4 to
test ext4 with fuse2fs. Change all the library code as needed to handle
this new type alongside all the existing ext[234] checks, which seems a
little cleaner than FSTYP=fuse FUSE_SUBTYPE=ext4, which also would
require even more treewide cleanups to work properly because most
fstests code switches on $FSTYP alone.

I agree that FSTYP=fuse.ext4 is cleaner than
FSTYP=fuse FUSE_SUBTYPE=ext4
but it is not extendable to future (e.g. fuse.xfs)
and it is still a bit ugly.
Consider:
FSTYP=fuse.ext4
MKFSTYP=ext4
I think this is the correct abstraction -
fuse2fs/ext4 are formatted that same and mounted differently
See how some of your patch looks nicer and naturally extends to
the imaginary fuse.xfs...

Maybe I'd rather do it the other way around for fuse4fs:
FSTYP=ext4
MOUNT_FSTYP=fuse.ext4
(obviously, MOUNT_FSTYP=$FSTYP if the test runner hasn't overridden it)
Where $MOUNT_FSTYP is what you pass to mount -t and what you'd see in
/proc/mounts. The only weirdness with that is that some of the helpers
will end up with code like:
case $FSTYP in
ext4)
# do ext4 stuff
;;
esac
case $MOUNT_FSTYP in
fuse.ext4)
# do fuse4fs stuff that overrides ext4
;;
esac
which would be a little weird.
_scratch_mount would end up with:
$MOUNT_PROG -t $MOUNT_FSTYP ...
and detecting it would be
grep -q -w $MOUNT_FSTYP /proc/mounts || _fail "booooo"
Hrm?

Sounds weird, but there is always going to be weirdness
somewhere - need to pick the least weird result or most
easy to understand code IMO.

Those look obviously nice.
Maybe the answer is to have all MOUNT_FSTYP, MKFS_FSTYP
and FSTYP and use whichever best fits in the context.

Hrmm well I would /like/ avoid adding MKFS_FSTYP since ext4 is ext4, no
matter whether we're using the kernel or fuse42fs. Do you have a use
case for adding such a thing?

No use case, beyond more flexibility in writing clear code.
I agree with Zorro that ext4 is not only ext4.
ext4 is ext4 on-disk format and it is ext4 driver and this ambiguity
can be a source of confusion sometimes.
I don't see the problem with defining MKFS_FSTYP
the controversial part IMO is what FSTYP should be
referring to, the flesh or the spirit...
Trying to think up a use case, ntfs has at least 3 Linux drivers
that I know of (ntfs,ntfs3 and fuse.ntfs-3g) and another one that was recently
proposed (ntfsplus). At least some have also their matching mkfs
and should be able to cross mount an ntfs formatted by other mkfs.
So testing any variation of MKFS_FSTYP and MOUNT_FSTYP
makes sense.
Using MKFS_FSTYP in mkfs and fsck helpers and using MOUNT_FSTYP
in mount helpers is always good practice IMO.
My intuition is that FSTYP should be defined to whichever
results in less churn and less weird looking code, but I don't know
which one that would be.
Thanks,
Amir.

... this ^^^, I think this discussion brings in a topic:
If the same on-disk fstype can be mounted with different drivers, what does
original $FSTYP stand for? Is it stand for the running fs driver, or the the
on-disk fs type? Besides the code looks ugly or not, the basic parameters must
be clear in meaning I think.
If the same on-disk fstype can be mounted with different drivers, we might
need two parameters to avoid this confusion. Due to we sometimes depends on
the on-disk type, e.g. mkfs, fsck, xfs_db, metadump and so on, sometimes
depend on running-time fs driver, e.g. mount, quota and so on.
We can let FSTYP stands for the running-time fs driver, as it's mostly treated
as that I think. And set MKFSTYP=$FSTYP by default, if MKFSTYP isn't specified.
Then change those "FSTYP judgement" code to MKFSTYP, if they need ondisk fstype
actually.
I don't mind the parameter name, but the meaning should not be confused. What
do you think? Feel free to correct me if I miss anything.
Thanks,
Zorro

mke2fs disables foreign filesystem detection no matter what type you
pass in, so we need to block this for both fuse server variants.

If you accept my previous suggestion of MKFSTYP, then could add:
[[ $MKFSTYP =~ $1 ]] && \
_notrun "not suitable for this filesystem on-disk
format: $MKFSTYP"

And then you wont need to add fuse.ext[234] to exclude list
At the (very faint) risk of having a test that only wants to exclude ext4 and
does not want to exclude fuse.ext4, I think this is worth it.

I guess we could try to do [[ $MKFSTYP =~ ^$1 ]]; ?

Yeh of course, either that or [ $MKFSTYP = $1 ]
if we do not care to add pattern matching.

This program wants to create a large directory htree index, and it
doesn't care what the children are. Reduce the runtime of this program
by 2/3 by using hardlinks when possible instead of allocating 400,000
new child files. This is an even bigger win for fuse2fs, which has a
runtime of 6.5h.

Could you also clean up the corresponding comments?
# ext* has supported all variants of swap files since their
# introduction, so swapon should not fail.
At present, swap files don’t support block sizes greater than the page
size, which means swapon will fail when LBS is enabled.

Well at that point we might as well collapse everything into:
if ! swapon "$SCRATCH_MNT/swap" >/dev/null 2>&1; then
_scratch_unmount
_notrun "swapfiles are not supported for $FSTYP"
fi
(note the removal of the case "$FSTYP"...esac code)

Agreed. I don't think the ext4 special case makes sense here. If we
want to have a specific "swapfiles are working when we expect them
to", let's do that as a single file system specific test. Let's keep
_require_scratch_swapfile simple.

In _require_scratch_swapfile, skip the test if swapon fails for whatever
reason, just like all the other filesystems. There are certain ext4
configurations where swapon isn't supported, such as S_DAX files on
pmem, and (for now) blocksize > pagesize filesystems.

From: Darrick J. Wong <djwong@kernel.org>
Remounting a filesystem should be pretty straightforward invocation of
mount -o remount,XXX. Instead, we go through _try_scratch_mount, which
recomputes the filesystem type and the mount options, which is probably
not what the caller actually wanted. Streamline this by calling the
_mount wrapper directly.
This also means that /sbin/mount.$FSTYP won't be invoked for a remount,
which doesn't work if that binary is actually a fuse filesystem driver.

libext2fs doesn't know how to create the htree indexes for a directory,
so fuse2fs doesn't either. Amend common/populate not to check for
htree.

Use the purpose-built scratch filesystem remount helper so that we don't
waste time recomputing mount options. This is needed for any filesystem
with a mount helper (i.e. /sbin/fs/mount.$FSTYP) because mount(8)
assumes that every helper is smart enough to find an existing mount and
remount it... and some of them like fuse2fs are not that smart.

Don't rely on mount(8) or the kernel to autodetect the filesystem type
when mounting a formatted image; if we are testing a different driver
(e.g. fuse2fs for ext4 filesystems) then the autodetection picks the
wrong driver.

Explicitly format with the given FSTYP so that if we're testing
fuse.ext4, we actually get the fuse-specific formatting options that
might be in the config file.

Refactor these open-coded calls so that we can use the standard
formatting helper functions and thereby get the correct fs feature set.

fuse2fs (when installed as a mount.fuse.ext4 helper program) doesn't
handle the case where someone tries to mount the same device multiple
times because there's no way for userspace to find an existing mount and
bind mount it to the new mountpoint like the kernel does.

Create a new helper function to skip tests on setups where online resize
is not supported. fuse2fs does not support this, whereas Linux ext4
does, so we need some means to distinguish.

fuse2fs' fallocate implementation follows xfs' behavior of failing an
fallocate up front if there isn't enough free space in the filesystem to
allocate @len bytes, even if most of the range is actually already
allocated. This is an engineering decision on the part of the author
(me) not to support the corner case of preallocating a not very sparse
file because that would just be more code to maintain.

fuse2fs doesn't create htree indices for directories because libext2fs
doesn't support creating them. When testing the kernel driver this test
runs in a few seconds, but on fuse2fs it takes ten minutes to create the
small directory with minimally sized names, and three hours more to
create a very large directory with long names.
This is silly for a test that really just wants to make sure that we can
create a directory with a lot of child subdirectories. Skip the long
test on fuse2fs. We probably don't even need the long test.

fuse_bdi_init disables writeback accounting on its bdi, so there's no
point in trying to measure the accounting for any block devices that the
fuse server might have open.

From: Darrick J. Wong <djwong@kernel.org>
This test checks that directio reads still work ok if nolock is enabled.
Therefore, if the filesystem driver won't mount with dioread_nolock,
skip the test because its preconditions are not satisfied.

From: Darrick J. Wong <djwong@kernel.org>
This test fails on fuse2fs with the following:
+mount: /opt/merged0: wrong fs type, bad option, bad superblock on overlay, missing codepage or helper program, or other error.
+ dmesg(1) may have more information after failed mount system call.
dmesg logs the following:
[ 764.775172] overlayfs: upper fs does not support tmpfile.
[ 764.777707] overlayfs: upper fs does not support RENAME_WHITEOUT.
From this, it's pretty clear why the test fails -- overlayfs checks that
the upper filesystem (fuse2fs) supports RENAME_WHITEOUT and O_TMPFILE.
fuse2fs doesn't support either of these, so the mount fails and then the
test goes wild.
Instead of doing that, let's do an initial test mount with the same
options as the workers, and _notrun if that first mount doesn't succeed.
Fixes: 210089cfa00315 ("generic: test a deadlock in xfs_rename when whiteing out files")

Yes, this works too. Since this is your code, could you send it to the
list with a proper commit message (or even just copy mine) and then I
can ack it?

Attached.
Now it's even tested.
I put you down as Suggested-by.
Feel free to choose your own roles...

Subject: [PATCH] generic/631: don't run test if we can't mount overlayfs
This test fails on fuse2fs with the following:
mount: /opt/merged0: wrong fs type, bad option, bad superblock on overlay,
missing codepage or helper program, or other error.
dmesg(1) may have more information after failed mount system call.
dmesg logs the following:
[ 764.775172] overlayfs: upper fs does not support tmpfile.
[ 764.777707] overlayfs: upper fs does not support RENAME_WHITEOUT.
From this, it's pretty clear why the test fails -- overlayfs checks that
the upper filesystem (fuse2fs) supports RENAME_WHITEOUT and O_TMPFILE.
fuse2fs doesn't support either of these, so the mount fails and then the
test goes wild.
Instead of doing that, let's do an initial test mount with the same
options as the workers, and _notrun if that first mount doesn't succeed.
Fixes: 210089cfa00315 ("generic: test a deadlock in xfs_rename when whiteing out files")

_get_mount depends on the ability for commands such as "mount /dev/sda
/a/second/mountpoint -o per_mount_opts" to succeed when /dev/sda is
already mounted elsewhere.
The kernel isn't going to notice that /dev/sda is already mounted, so
the mount(8) call won't do the right thing even if per_mount_opts match
the existing mount options.
If per_mount_opts doesn't match, we'd have to convey the new per-mount
options to the kernel. In theory we could make the fuse2fs argument
parsing even more complex to support this use case, but for now fuse2fs
doesn't know how to do that.
Until that happens, let's _notrun these tests.

I believe this is true for fuse* in general. no?

I think it's actually true any time mount shells out to a mount helper
because you gave it a -t FOO and there happens to be a mount.FOO in
$PATH. Though I wonder if I could/should just bloat up fuse4fs to
detect when the device is already open to the same mountpoint, and just
call mount(8) back with --internal?

fuse2fs only supports fiemap in iomap mode, so disable this test when

Is this statement correct in general for fuse or specifically for fuse2fs?
If general, than I would rather foresee fuse.xfs and make it:
if [[ ! "$FSTYP" =~ fuse.* ]];

No, just for fuse2fs. Who knows what fuse.xfs is going to do, we
haven't written it yet....

If you try to test ext4 with 8k block size, this test will hang forever
on:
mke2fs 1.47.4~WIP-2025-07-09 (9-Jul-2025)
mkfs.fuse.ext4: 8192-byte blocks too big for system (max 4096)
Proceed anyway? (y,N)
Because we invoked mkfs directly

QA output created by 006

+e2fsck did not fix everything
finished fuzzing
The reason for this is that the $ROUND2_LOG file has five lines in it:
++ mount image (2)
++ chattr -R -i
++ test scratch
++ modify scratch
+++ stressing filesystem
++ unmount
When I wrote this test there were more things that common/fuzzy tried to
do. Commit 9bab148bb3c7db reduced the _scratch_fuzz_modify output from
3 lines to 1, which accounts for the discrepancy.
Fix this by counting the lines that do /not/ start with two pluses and
failing if there's at least one such line.
Cc: <fstests@vger.kernel.org> # v2023.02.26
Fixes: 9bab148bb3c7db ("common/fuzzy: exercise the filesystem a little harder after repairing")

This can happen if the amount of space requested by fallocate exceeds
the number of reserved blocks in the filesystem. Reduce the fallocation
requests a little bit to prevent this.

What a commit message!
ext4/022: adjust to fuse2fs i_extra_size behavior
fuse2fs doesn't get fancy about changing i_extra_size in response to
changes in the xattr structure, so it needs a separate .out file to
reflect that.

This test almost works for fuse servers, but needs some fixes:
First, fuse servers do not receive the ->mark_dead notifications that
kernel filesystems receive. As a result, the read that happens after
the scsi_debug device goes down could very well be served by cached file
data in the fuse server. Therefore, cycle the mount before reopening
the victim file to flush all cached file data.
Second, the fuse server might decide to go read-only when the read
fails. In this case, the "cat <&3 > /dev/null" might produce an
additional error when it tries to close "standard input". These need to
be filtered out too.

generic/113 seems to blow up fuse+iomap and the fs doesnt even get
marked corrupt so yeah

I find the series a bit hard to follow, because it mixes generic
with fs specific with test specific patches totally randomly. Can
you get a bit of an order into it? And maybe just send a series
with the conceptual core changes first outside the giant patch bombs?
Or if parts are useful outside the fuse ext4 context just send them
out in a self-contained series? Bonus points for a bit of a highlevel

Well TBH there's a lot of accumulated stuff including some treewide
cleanups in my fstests branch that needs to go upstream before the
fuse2fs changes. I've been waiting the entire year to see if
check-parallel will get finished... and I'm not going to wait anymore.
That's why I haven't tidied up this patchset at all.
The TLDR version is that FSTYP=fuse.ext4 is how you select the fuse
server, and you ought to have mkfs.fuse.ext4/fsck.fuse.ext4 point to the
appropriate e2fsprogs programs; a [fuse.ext4] section in mke2fs.conf;
and fuse4fs installed as /sbin/mount.fuse.ext4 or /sbin/ext4 depending
on how your libfuse is configured.
Then this series is basically making sure that FSTYP=fuse.ext* works,
and turning off feature tests for things that aren't supported by
fuse2fs.
