Ross Zwisler 8b71ca4162 build: fix _BSD_SOURCE complier warning
When compiling xfstests with either gcc 6.4.1 or 7.2.1 I see the
following warning:

In file included from /usr/include/stdio.h:27:0,
                 from fssum.c:25:
/usr/include/features.h:148:3: warning: #warning "_BSD_SOURCE and _SVID_SOURCE
are deprecated, use _DEFAULT_SOURCE" [-Wcpp]
 # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"
   ^~~~~~~

The feature_test_macros(7) man page says this about _BSD_SOURCE:

 Since glibc 2.20, this macro is deprecated. It now has the same
 effect as defining _DEFAULT_SOURCE, but generates a compile-time
 warning (unless _DEFAULT_SOURCE is also defined). Use
 _DEFAULT_SOURCE instead.  To allow code that requires _BSD_SOURCE
 in glibc 2.19 and earlier and _DEFAULT_SOURCE in glibc 2.20 and
 later to compile without warnings, define both _BSD_SOURCE and
 _DEFAULT_SOURCE.

Keep backwards compatibility with older code by defining both
_BSD_SOURCE and _DEFAULT_SOURCE.

Ross Zwisler 729b2bc764 generic: add test for DAX MAP_SYNC support
This test creates a file and writes to it via an mmap(), but never
syncs via fsync/msync. This process is tracked via dm-log-writes,
then replayed.

If MAP_SYNC is working the dm-log-writes replay will show the test
file with 1 MiB of on-media block allocations.  This is because each
allocating page fault included an implicit metadata sync.  If
MAP_SYNC isn't working (which you can test by removing the "-S" flag
to xfs_io mmap) the file will be smaller or missing entirely.

Note that dm-log-writes doesn't track the data that we write via the
mmap(), so we can't do any data integrity checking.  We can only
verify that the metadata writes for the page faults happened.

[eguan: add comments on _require_log_writes_dax and fix its cleanup]

Ross Zwisler 1475bdd1f7 dm-log-writes: only replay log to marks that exist
The 'replay-log' executable will replay the dm-log-writes log until
the given mark, or until the end of the log if the mark isn't found.

This means that if the mark you're looking for was never inserted in
the log or if you give garbage to _log_writes_replay_log() the
entire log will be replayed.  This can cause unexpected test
results.

Fix this by making sure that the mark we're given actually exists in
the log before we allow the replay.

Qu Wenruo 88231c0c0b btrfs: make sure btrfs can handle full fs trim correctly
Ancient commit f4c697e6406d ("btrfs: return EINVAL if start >
total_bytes in fitrim ioctl") introduced a regression where btrfs
may fail to trim any free space in existing block groups.

It's caused by confusion with btrfs_super_block->total_bytes and
btrfs logical address space.

Unlike physical address, any aligned bytenr in range [0, U64_MAX) is
valid in btrfs logical address space, and it's chunk mapping
mechanism of btrfs to handle the logical<->physical mapping.

The test case will craft a btrfs with the following features:
0) Single data/meta profile
   Make trimmed bytes reporting and chunk allocation more predictable.

1) All chunks start beyond super_block->total_bytes (1G)
   By relocating these blocks several times.

2) Unallocated space is less than 50% of the whole fs

3) Fragmented data chunks
   Data chunks will be full of fragments, 50% of data chunks will be
   free space.

So in theory fstrim should be able to trim over 50% space of the fs.
(after fix, 64% of the fs can be trimmed)

While the regression makes btrfs only able to trim unallocated
space, which is less than 50% of the total space.
(without fix, it's only 31%)

Fixed by patch named "btrfs: Ensure btrfs_trim_fs can trim the whole
fs".

Amir Goldstein 959081e0d3 overlay/042: remove wrong check for empty index
The check for empty index in this test was wrongly copied from test
overlay/034. In test overlay/034 lower file starts as a hardlink, so
nlink accounting is done from the first copy up and index can be cleaned
on last upper hardlink unlink. In this test, lower starts as
non-hardlink, so first copy up does not perform nlink accounting and
therefore, union nlink count does not drop to 0 at the end of the test
and the index is not expected to be cleaned.

In ext4 data=journal mode, direct read will fall back to buffer
read, and buffer read doesn't take inode lock, so it doesn't need to
wait for the writer to finish first and sees the intermediate inode
size and returns data less than 1M.

We can just check the actual read data instead of the whole read
buffer.

Eryu Guan 94d3a4f00c fstests: filter mount error message for EUCLEAN and ESTALE
util-linux commit ea848180dd34 ("libmount: add
mnt_context_get_excode()") since v2.30 changed the error message on
EUCLEAN and ESTALE again (and maybe other errno too):

 - mount: <device> on <mountpoint> failed: Structure needs cleaning
 + mount: <mountpoint>: mount(2) system call failed: Structure needs cleaning.

and it causes xfs/005, overlay/037 to fail (and probably xfs/333 too,
but it's always _notrun for now).

And what's more, the mentioned tests would also fail when testing
with util-linux prior to v2.21, no one complained just because the
tests are usually _notrun on such old distributions that ship
util-linux < v2.21.

So let's filter out the changing parts and keep the error message
simple.

Josef Bacik c134a345f7 fstests: add fio perf results support
This patch does the nuts and bolts of grabbing fio results and
storing them in a database in order to check against for future
runs.  This works by storing the results in resuts/fio-results.db as
a sqlite database.  The src/perf directory has all the supporting
python code for parsing the fio json results, storing it in the
database, and loading previous results from the database to compare
with the current results.

This also adds a PERF_CONFIGNAME option that must be set for this to
work.  Since we all have various ways we run fstests it doesn't make
sense to compare different configurations with each other (unless
specifically desired).  The PERF_CONFIGNAME will allow us to
separate out results for different test run configurations to make
sure we're comparing results correctly.

Currently we only check against the last perf result.  In the future
I will flesh this out to compare against the average of N number of
runs to be a little more complete, and hopefully that will allow us
to also watch latencies as well.
