[PATCH 0/7] xfstests: minor fixes for the reflink/dedupe tests

[Darrick J. Wong]

This is a patch set for xfstests that adds some more reflink tests
and fixes problems with some of the existing reflink tests.  Most
notably, I fixed the problems with the ENOSPC tests trying to use
the ENOSPC'd fs for loop control -- bad bad bad.

Comments and questions are, as always, welcome.  The fixes are
available on github[1].

[PATCH 2/7] tests: don't put loop control files on the scratch mount

[Darrick J. Wong]

If we're doing write/overwrite/snapshot/resource exhaustion tests on
the scratch device, use the test directory to hold the loop
termination signal files.  This way we don't run infinitely because we
can't create the flag due to ENOSPC.

[PATCH 2/7] tests: don't put loop control files on the scratch mount

[Darrick J. Wong]

If we're doing write/overwrite/snapshot/resource exhaustion tests on
the scratch device, use the test directory to hold the loop
termination signal files.  This way we don't run infinitely because we
can't create the flag due to ENOSPC.

[PATCH 5/7] reflink: test interaction with swap files

[Darrick J. Wong]

Since none of the current filesystems support reflinked swap files,
make sure that we prohibit reflinking of swapfiles and swapon of
reflinked files.

[PATCH 6/7] xfs: test rmap behavior when multiple bmbt records map to a single rmapbt record

[Darrick J. Wong]

Make sure that we can handle multiple bmbt records mapping to a
single rmapbt record.  This can happen if you fallocate more than
2^21 contiguous blocks to a file.

(Also add some helpers that can create huge devices with some dm-zero
and dm-snapshot fakery.)

question about xfs/122

[Xiao Yang]

Hi Darrick

When i run xfstests test case xfs/122 on RHEL7.2GA with xfsprog-dev(4.5.0),
I always get such error about xfs/122:
---------------------------------------------------------
  sizeof(struct xfs_extent_data_info) = 32
  sizeof(struct xfs_fs_eofblocks) = 128
  sizeof(struct xfs_icreate_log) = 28
-sizeof(struct xfs_refcount_key) = 4
-sizeof(struct xfs_refcount_rec) = 12
-sizeof(struct xfs_rmap_key) = 4
-sizeof(struct xfs_rmap_rec) = 24
-sizeof(struct xfs_rmapx_key) = 20
  sizeof(xfs_agf_t) = 224
  sizeof(xfs_agfl_t) = 36
  sizeof(xfs_agi_t) = 336
---------------------------------------------------------

This case can pass with modern xfsprogs(i.e. 4.3+ and all the new v5 stuff) as you said.
Could you tell me which specific version can support this case. In addition, what can be
done to work around this failure.

Please advise. Thanks very much.

Regards,
Xiao Yang

That's a bit of an odd loop, and it would seem an inverted grep
would seem more obvious.  But otherwise this looks fine to me:

Re: [PATCH 2/7] tests: don't put loop control files on the scratch mount

[Christoph Hellwig]

Shouldn't these tests also add a _require_test now?  But we probably
should just move them to /tmp instead?

Ah, thanks.  I've actually prepared a patch to fix swapon in the kernel
and was about to start writing test cases for it.  I hope you haven't
also done the kernel work already :)

It doesn't, this somehow jumped patches when I rebased. :/

I'm just gonna say 'thinko' and respin. :)

/me pours a larger cup of coffee...

The missing fields are for the reflink and rmap btrees.  I could say
to just ignore it, but I don't want to establish a precedent of
ignoring xfs/122 errors...

I'm wondering if perhaps this test ought to filter out /missing/ lines
in the test output?

[PATCH v2 2/7] tests: don't put loop control files on the scratch mount

[Darrick J. Wong]

If we're doing write/overwrite/snapshot/resource exhaustion tests on
the scratch device, use the test directory to hold the loop
termination signal files.  This way we don't run infinitely because we
can't create the flag due to ENOSPC.

v2: put the control files in /tmp, not $TEST_DIR

[PATCH v2 6/7] xfs: test rmap behavior when multiple bmbt records map to a single rmapbt record

[Darrick J. Wong]

Make sure that we can handle multiple bmbt records mapping to a
single rmapbt record.  This can happen if you fallocate more than
2^21 contiguous blocks to a file.

(Also add some helpers that can create huge devices with some dm-zero
and dm-snapshot fakery.)

v2: remove irrelevant t_immutable changes, put test in correct group

[PATCH] xfs/122: add check number of structure

[Xiao Yang]

I think the number of structure is always changing based on
different xfsporg-dev version. If some expected structure is
missing in current environment, we won't check structure size
and offset and set the result to notrun.

I think the number of structure is always changing based on different 
xfsporg-dev version.
Can we determine whether all expected structure exist in current 
enviroment or not by comparing
line number of standard output with line number of actual output? If the 
line number of actual
output is less than expeted number of structure, we trust that some 
structure is missing and set
test result to not run.

I think the maintainer only cares that xfs/122 passes when run against
current xfsprogs git.

For certain, this shouldn't be hardcoded to 148.

[PATCH 8/7] xfs/122: don't break on old xfsprogs

[Darrick J. Wong]

If we're running against a old version of xfsprogs that lacks some of
the structures that the golden output knows about, copy the structure
size definition from the golden output to the program output.  This
way we can check for structure size mutations on old xfsprogs without
generating false error reports for structs that don't exist in the
old release.

Re: [PATCH 8/7] xfs/122: don't break on old xfsprogs

[Christoph Hellwig]

Looks fine, but can't we also remove the workaround at the end of the
the test as well?

Oh, heh, yes, those can go.  The whitespace is wrong on them anyway.

[PATCH v2 8/7] xfs/122: don't break on old xfsprogs

[Darrick J. Wong]

If we're running against a old version of xfsprogs that lacks some of
the structures that the golden output knows about, copy the structure
size definition from the golden output to the program output.  This
way we can check for structure size mutations on old xfsprogs without
generating false error reports for structs that don't exist in the
old release.

v2: Remove the xfsprogs 2.9.8 compatibility cruft.
