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/ocfs2/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.
Issues:
* I think the race checks for dedupe could be a little sharper at
finding mistakes.
* The realtime reflink test (xfs/804) crashes XFS before we even get
to the reflink attempt.
* I started the numbering really high to prevent the tests from
colliding with whatever new tests might arrive; this will require
some intervention to fix.
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.

Move the cp --reflink tests from btrfs/ to generic/ since xfs now
supports that ioctl.

* [PATCH 01/11] btrfs: move btrfs reflink tests to generic
@ 2015-11-11 19:26 ` Darrick J. Wong

From: Darrick J. Wong @ 2015-11-11 19:26 UTC (permalink / raw)
To: hch, david, darrick.wong
Cc: fstests, xfs, tao.peng, linux-ext4, Anna.Schumaker, linux-btrfs
Move the cp --reflink tests from btrfs/ to generic/ since xfs now
supports that ioctl.

* [PATCH 05/11] reflink: test the various fallocate modes

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 05/11] reflink: test the various fallocate modes
@ 2015-11-11 19:27 ` 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 07/11] reflink: test accuracy of free block counts

To: hch, david, darrick.wong
Cc: fstests, xfs, tao.peng, linux-ext4, Anna.Schumaker, linux-btrfs
Check that the free block counts seem to be handled correctly in
the reflink operation and subsequent attempts to rewrite reflinked
copies.

* [PATCH 07/11] reflink: test accuracy of free block counts

From: Darrick J. Wong @ 2015-11-11 19:27 UTC (permalink / raw)
To: hch, david, darrick.wong
Cc: fstests, xfs, tao.peng, linux-ext4, Anna.Schumaker, linux-btrfs
Check that the free block counts seem to be handled correctly in
the reflink operation and subsequent attempts to rewrite reflinked
copies.

* [PATCH 10/11] reflink: test what happens when we hit resource limits

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

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 11/11] reflink: test that CoW writes fail when we're out of space
@ 2015-11-11 19:27 ` Darrick J. Wong
0 siblings, 0 replies; 38+ messages in thread
From: Darrick J. Wong @ 2015-11-11 19:27 UTC (permalink / raw)

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.

Looks fine:

some of the free block range stuff might need minor fixups for certain
file systems later, but I'd rather do this once all the patches are

works dedup works as well, leading to lots of false failures on nfs.

Bleargh, _require_*_dedupe forgot to check for ENOTTY output, so all the dedupe
tests should have _notrun.
Also, generic/806 was calling the wrong _require.
I'll start renumbering tests; Christoph, did you see anything else?

I think I got all the tests renumbered correctly and fixed all the other bugs.
I'd like to send the updated patchpile to Dave tomorrow, but if you have a few
spare cycles would you mind giving this a quick test to make sure I fixed
everything?

Looks good enough to go in
Acked-by: Christoph Hellwig <hch@lst.de>
I have for failing tests on NFS currently. Two of them probably are
NFS issues (free block count), but and two others fail because NFS
doesn't support chattr/lsattr. I will send an incremental check to adda
feature test for those.

I separated the chattr +i tests into a separate test that doesn't run if lsattr
doesn't make sense; will post patches shortly.
