Hi all,

This series adds to fsx support for FICLONERANGE, FIDEDUPERANGE, and
copy_file_range.  It adds to fsstress support for copy_file_range.
There are known failures in 4.20-rc2, particularly with copy_file_range,
so these patches provide a fstests base for everyone to start/continue
looking for bugs.

Hi Darrick,

Your patches triggered 2 new failures on g/091 and g/263, refer to [1]. I can't
reproduce these failures on original xfstests [2]. I saw you were talking about g/091
in #xfs. Are these two failures same issue?

Thanks,
Zorro

And a g/127 failure can be reproduced sometimes, on XFS with "-m reflink=1,rmapbt=1 -b size=2048":
# for ((i=0; i<10; i++));do echo "The ${i}th time"; ./check generic/127 || break;done

Yup, there's lots of bugs in the code that fsx now exercises. These
tests will now fail until we get the fixes into the upstream kernel.

And, really, even when these tests pass (as they do on my machines
now) fsx still fails. I have at least 4 different failures which
occur at between 350k and 5m ops that I can reproduce. These tests
only run about 10-100k ops, so they don't trip over the bugs I
haven't found and fixed yet.

Cheers,

Dave.

Hi Darrick,

I just tried NFS, [1] tested with original xfstests, [2] tested with your
patches. Looks like your patches bring in new failures to NFS test:
g/075, g/112 and g/127.

Thanks,
Zorro

Uh... it would be much more helpful to send along the golden output
diffs that show where fsx went bad (as well as the nfs configuration),
but yes, in general we found a lot of corruption problems and I only
sent off a pull request w/ the fixes just now.

(I've also been trying to reproduce the EFSCORRUPTED failure in
generic/127, but haven't been able to hit that yet...)

I was testing against a loop-mount nfsv4.2 server. The diff is like

+Correct content saved for comparison

And it seems like that NFSv4 doesn't like clone_file_range if src and
dst point to the same file.

Hmm, well, -EAGAIN isn't documented as a valid return code in the

should probably amend do_copy_file_range to use syscall() so that we
don't pick up the glibc wrapper by the same name.

I typed the wrong operation name.. it should be "copy_file_range" not
"clone_file_range".

And if I do a manual test on NFSv4.2, I got

# xfs_io -fc "copy_range -s 0 -d 0 -l 5 /mnt/test/fsx/112.0" /mnt/test/fsx/112.0
copy_range: Invalid argument

# xfs_io -fc "copy_range -s 0 -d 0 -l 0 /mnt/test/fsx/112.0" /mnt/test/fsx/112.1

copy_range on the same file fails with "Invalid argument" but copy to a
new file succeeds. So I guess NFS doesn't like/support copy_file_range
if src == dst.

Thanks,
Eryu

Aha, yes... it's right there in nfs4_copy_file_range.  Uggh.

<nod> Ok, I'll rework the test_copy_range function to try a 1-byte copy.
Thanks for the info.

fsx is always going to fail with NFSv4.2 and copy_file_range() right
now, because NFS does not allow copy offload within the same file.
i.e. it only allows copying between different files.

Precisely - this is /currently/ an expected failure on NFS.
