[RFCv3.2 00/12] xfstests: test the nfs/cifs/btrfs/xfs reflink/dedupe ioctls

[Darrick J. Wong]

Hi all,

This is part of the third revision of an RFC for adding to XFS support
for tracking reverse-mappings of physical blocks to file and metadata;
and support for mapping multiple file logical blocks to the same
physical block, more commonly known as reflinking.

This patchset aims to make xfstests perform more rigorous testing of
the NFS/CIFS/btrfs/XFS file clone, reflink, and dedupe ioctls.
There are now tests of the basic functionality of the three ioctls;
tests to ensure that the filesystem exhibits the expected copy on
write semantics; tests to try to suss out race conditions in the new
write paths; tests to ensure that the ioctls peform basic disk
accounting correctly; tests of the interaction between reflink and the
various fallocate verbs (allocate, punch, collapse, insert zeroes);
and some attempts to test the upper limits of reflinking and ENOSPC
behavior.

Since the last posting, each test tries to reflink (or dedupe) on the
test or scratch FS to decide if they're going to run, instead of
guessing based on FS type.  Per Dave's suggestion, I also converted
the basic functionality tests to use fixed sizes so that I can use
md5sum in the golden output to check that the file contents match
exactly.

Since "RFCv3.1", I've made the following changes:

 * Renumbered the tests to the lowest numbers possible, per Dave's
   request.

 * Fixed the reflink and dedupe _require tests so that they can run
   on things like NFS which support reflink but not dedupe.

 * Added checks for lsattr/chattr support so that we don't produce
   bogus failures on NFS, and put the *attr tests in separate test
   files.

 * Appended a couple of tools I wrote to handle finding minimal test
   numbers and moving tests around.

If you're going to start using this mess, you probably ought to just
pull from my github trees for kernel[1], xfsprogs[2], xfstests[3], and
xfs-docs[4].  They should just work with the btrfs that's in 4.3...
and somewhat buggily with the 4.3 XFS patched with [1].

Comments and questions are, as always, welcome.

[PATCH 01/12] test-scripts: test migration scripts

[Darrick J. Wong]

Add two scripts: "nextid" finds the next available test ID number in a
group, and "mvtest" relocates a test, fixes the golden output, and
moves the group entry for that test.

These should be placed in the "tools" directory.

$DBG?

What does this do to comments in the group file?

So the "new" script does this differently, by reading the group
file and looking for the first non-contiguous ID in the file. It
doesn't need scan ID limits because EOF triggers that. Wouldn't it
be better to to factor the code out of the "new" script to find the
next id, and then have the new script call that?

Cheers,

Dave.

"DBG=echo ./mvtest foo bar" to see what it would have run, more or less.

(I suppose I could getopt a --dry-run, but I could also just get rid of them.)

Eats them.  I don't know of a good way to sort just the uncommented lines
in the file, short of writing a python script to do that.

I guess it's not that hard; I've sort of needed one here and there over
the years, but never wrote one, and $google doesn't immediately provide
any such thing.

In the end I wrote a short Python program to sort group files and it wasn't
much harder to reuse the code to implement nextid, so I did that instead.

I'll probably post this and a patch to fix the error codes in generic/157
later this week.

[PATCH 06/12] reflink: test the various fallocate modes

[Darrick J. Wong]

Check that the variants of fallocate (allocate, punch, zero range,
collapse range, insert range) do the right thing when they're run
against a range of reflinked blocks.

[PATCH 11/12] reflink: test that CoW writes fail when we're out of space

[Darrick J. Wong]

Ensure that copy-on-writing a reflinked file when there's no free disk
space reflects the desired ENOSPC back to userspace during the write
call.  Tests the buffered IO, direct IO, and mmap write paths.

[PATCH 12/12] reflink: test what happens when we hit resource limits

[Darrick J. Wong]

Add a few horrible opt-in stress tests to see what happens if we try
to reflink the same block billions of times, and what happens if we
run out of space while reflinking a file.
