9bf6b5c837 btrfs-progs: tests: add json formatter test coverage
Add a simple framework to exercise the json formatter and add testing
target that validates the output.

Run 'make test-json' to execute all available tests, requires 'jq'
utility for validation (https://github.com/stedolan/jq).

ce7ab16441 btrfs-progs: tests: add Makefile for testsuite
Add a Makefile so tests can be run the same way from the standalone
testsuite as they are from git. The build dependencies are not checked
and the default path is for the system binaries.

Because of the path auto detection, running 'make' from the tests/
directory now works the same way as from the toplevel git directory.

b3417b02aa btrfs-progs: tests: enhance invalid extent item generation test cases
This patch will:

- Add a new test image for fsck/044
  This new image has a corrupted extent item generation for tree block.
  This image can expose a bug in original mode, which can't detect the
  problem.
  This image also utilize the tree block generation detection code,
  which the existing image doesn't.

- Rename the existing image
  To reflect the fact that the existing one is only for data extent.

- Remove the test.sh
  So that the generic path will test both detection and repair.

92d92e99b7 btrfs-progs: mkfs: support free space tree as -R option
Add a runtime feature (-R) flag for the free space tree. A filesystem
that is mkfs'd with -R free-space-tree then mounted with no options has
the same contents as one mkfs'd without the option, then mounted with
'-o space_cache=v2'.

The only tricky thing is in exactly how to call the tree creation code.
Using btrfs_create_free_space_tree as is did not quite work, because an
extra reference to the eb (root->commit_root) is leaked, which mkfs
complains about with a warning. I opted to follow how the uuid tree is
created by adding it to the dirty roots list for cleanup by
commit_tree_roots in commit_transaction. As a result,
btrfs_create_free_space_tree no longer exactly matches the version in
the kernel sources.

761add2622 btrfs-progs: tests: check that convert does not create extents beyond device boundary
Add a test case to check if the converted fs has device extent beyond
boundary.

The disk layout of source ext4 fs needs some extents to make them
allocated at the very end of the fs.  The script is from the original
reporter.

Also, since the existing convert tests always uses 512M as device size,
which is not suitable for this test case, make it to grab the existing
device size to co-operate with this test case.

23bee6a7b5 btrfs-progs: tests: update fsck/035-inline-bad-ram-bytes image
The image used in test case 035 has one problem:

- Bad total_bytes of device item in chunk tree
        item 0 key (DEV_ITEMS DEV_ITEM 1) itemoff 16185 itemsize 98
                devid 1 total_bytes 72564736 bytes_used 92274688
  The total_bytes is even smaller than bytes_used.
  While the dev_item in super block contains the correct value:
    dev_item.total_bytes    134217728
    dev_item.bytes_used     92274688

This patch will update the image, using the correct value in super block
to replace the wrong one in chunk tree.

So that later btrfs-image restore without device/chunk fixup can still
pass fsck-tests.

2f8071b6d3 btrfs-progs: tests: update fsck/012-leaf-corruption image
The image used in 012 has several problems:

- Bad dev_item total_bytes in superblock
    dev_item.total_bytes    20918272
    dev_item.bytes_used     67108864

  The fs has 64M chunks allocated, and the original fs is also 64M.
  Thus the total_bytes is completely wrong.

- Bad total_bytes in chunk tree
          item 0 key (DEV_ITEMS DEV_ITEM 1) itemoff 3897 itemsize 98
                devid 1 total_bytes 20918272 bytes_used 67108864
  The same problem as super block.

This problem is covered by btrfs-image, as it will recalculate the
device size.

However if btrfs-image is doing exactly same data replay without any
modification, such bad image would cause test failure, as we're unable
to fix such bad total_bytes.

This patch will update the image to fix such problem.
Also since we're here, there is no need to use custom .tar.gz image, as
we have extra_image() to handle the uncompression.

e445c1c381 btrfs-progs: tests: introduce expand_command() to inject aruguments more accurately
[PROBLEM]
We want to inject $INSTRUMENT (mostly valgrind) before btrfs command but
after root_helper.

Currently we won't inject $INSTRUMENT at all if we are using
root_helper.
This means the coverage is not good enough.

[FIX]
This patch introduce a new function, expand_command(), to handle all
parameter/argument injection, including existing 'btrfs check' inject.

This function will:
- Detect where to inject $INSTRUMENT
  If we have root_helper and the command is target command
  (btrfs/mkfs.btrfs/btrfs-convert), then we inject $INSTRUMENT after
  root_helper.
  If we don't have root_helper, and the command is target command,
  we inject $INSTRUMENT before the command.
  Or we don't inject $INSTRUMENT (it's not the target command).

- Use existing spec facility to inject extra arguments

- Use an array to restore to result
  To avoid bash interpret the IFS inside path/commands.

Now we can make sure no matter if we use root_helper, $INSTRUMENT is
always injected corrected.

8c759d5a06 btrfs-progs: tests: filter output for run_check_stdout
Since run_check_stdout() can insert INSTRUMENT for all btrfs related
programs, which could easily pollute the stdout, any caller of
run_check_stdout() should do proper filter.

The following callers are affected:
- misc/004
  Filter the output of "btrfs ins min-dev-size"

- misc/009
- misc/013
- misc/024
  They are all calling "btrfs ins rootid", so introduce get_subvolid()
  function to grab the subvolid properly.

- misc/031
  Loose the filter for "btrfs qgroup show". No need for "tail -n 1".

So we still have the same coverage, but now these tests won't cause
false alert if we insert INSTRUMENT for all btrfs commands.

Commit 31f477ee ("btrfs-progs: mkfs-tests: skip test if truncate fails

the $? expecting it to be an errno, when it actually returns 0 or 1.

To fix this test just check if the command failed (returned 1) and look
for the output, skipping the test if the OS cannot create a 6E file.

e711c843df btrfs-progs: tests/common: Don't call INSTRUMENT on mount command
[BUG]
With INSTRUMENT=valgrind set, some fsck tests will fail, e.g. fsck/013:
  ====== RUN CHECK mount -t btrfs -o loop /home/adam/btrfs/btrfs-progs/tests//test.img /home/adam/btrfs/btrfs-progs/tests//mnt
  ==114106==
  ==114106== Warning: Can't execute setuid/setgid/setcap executable: /usr/bin/mount
  ==114106== Possible workaround: remove --trace-children=yes, if in effect
  ==114106==
  valgrind: /usr/bin/mount: Permission denied
  failed: mount -t btrfs -o loop /home/adam/btrfs/btrfs-progs/tests//test.img /home/adam/btrfs/btrfs-progs/tests//mnt
  test failed for case 013-extent-tree-rebuild

[CAUSE]
Just as stated by valgrind itself, it can't handle program with
setuid/setgid/setcap.

Thankfully in our case it's mount and we don't really care about it at
all.

[FIX]
Although we could use complex skip pattern to skip mount in valgrind, we
don't really want to run valgrind on mount or sudo command anyway.

So here we do extra check if we're running mount command. And if that's
the case, just skip $INSTRUMENT command.

225d66e99b btrfs-progs: Include btrfs-find-root and btrfs-select-super in testsuite
These two binaries are not usually shipped with the package, but they
are used by the testsuite, they need to be included in the exported tar.

b20f94e984 btrfs-progs: misc-test: 034: Call "udevmadm settle" before mount
As seem in issue #192, this test can fail from time to time. The
issue happens when a mount is issued before the new device is processed
by systemd-udevd, as we can see by the og bellow:

  [ 2346.028809] BTRFS: device fsid 593e23af-a7e6-4360-b16a-229f415de697 devid 1 transid 6 /dev/loop10 scanned by systemd-udevd (3418)
  [ 2346.265401] BTRFS info (device loop10): found metadata UUID change in progress flag, clearing
  [ 2346.272474] BTRFS info (device loop10): disk space caching is enabled
  [ 2346.277472] BTRFS info (device loop10): has skinny extents
  [ 2346.281840] BTRFS info (device loop10): flagging fs with big metadata feature
  [ 2346.308428] BTRFS error (device loop10): devid 2 uuid cde07de6-db7e-4b34-909e-d3db6e7c0b06 is missing
  [ 2346.315363] BTRFS error (device loop10): failed to read the system array: -2
  [ 2346.329887] BTRFS error (device loop10): open_ctree failed

  failed: mount /dev/loop10 /home/marcos/git/suse/btrfs-progs/tests//mnt
  test failed for case 034-metadata-uuid
  make: *** [Makefile:401: test-misc] Error 1

  [ 2346.666865] BTRFS: device fsid 593e23af-a7e6-4360-b16a-229f415de697 devid 2 transid 5 /dev/loop11 scanned by systemd-udevd (3422)
  [ 2346.853233] BTRFS: device fsid 1c2debeb-e829-4d6b-84df-aa7c5d246fd5 devid 1 transid 7 /dev/loop6 scanned by systemd-udevd (3418)

A few moments after the test failed systemd-udevd processed the new
device (registered the new device under btrfs). This can be tested by
executing a mount after the test failed, resulting in a successful
mount:

  $ mount /dev/loop10 /mnt
  [ 2398.955254] BTRFS info (device loop10): found metadata UUID change in progress flag, clearing
  [ 2398.959416] BTRFS info (device loop10): disk space caching is enabled
  [ 2398.962483] BTRFS info (device loop10): has skinny extents
  [ 2398.965070] BTRFS info (device loop10): flagging fs with big metadata feature
  [ 2399.012617] BTRFS info (device loop10): enabling ssd optimizations
  [ 2399.022375] BTRFS info (device loop10): checking UUID tree

This problem can be avoided is we execute "udevadm settle" before the
mount is executed.
