The misc-test/034-metadata_uuid test case, has four sets of disk images
to simulate failed writes during btrfstune -m|M operations. As of now,
this tests kernel only. Update the test case to verify btrfstune -m|M's

57cd29c895 btrfs-progs: tests: return metadata_uuid or fsid as per METADATA_UUID flag
Previous commit "btrfs-progs: dump-super: print actual metadata_uuid
value" changed the value of the super_block::metadata_uuid to be printed
as it is, without tweaking it depending on the METADATA_UUID flag.

Apply similar tweak in the common helper functions used to read the
metadata_uuid so that test-cases still be successful.

cb19235991 btrfs-progs: tests: misc/046: fix false alerts on write detection
[BUG]
Test case misc/046-seed-multi-mount would always fail with the following
error:

    [TEST]   misc-tests.sh
    [TEST/misc]   046-seed-multi-mount
unexpected success: writable file despite read-only mount
test failed for case 046-seed-multi-mount

[CAUSE]
Although mounting seed device is indeed read-only, sprouting it with a
new device would always make it read-write by itself.

The behavior is already there for a long time, thus expecting a new
behavior (not changing the read-only flag) is a little weird.

[FIX]
Instead of doing the write check after the sprout, do it before the
sprout.

This looks more correct, and would not rely on the kernel behavior
change (if we determine to go that path).

e6b412b359 btrfs-progs: tests: misc/058: reduce the space requirement and speed up the test
[BUG]
When I was testing misc/058, the fs still has around 7GiB free space,
but during that test case, btrfs kernel module reports write failures
and even git commands failed inside that fs.

And obviously the test case failed.

[CAUSE]
It turns out that, the test case itself would require 6GiB (4 data
disks) + 1.5GiB x 2 (the two replace target), thus it requires 9 GiB
free space.

And obviously my partition is not that large and failed.

[FIX]
In fact, we really don't need that much space at all.

The test verifies that two consecutive replace operations can be started
and enqueued, the sleep of 1 second is not strictly necessary as the
first command should start the replace right away.

885fe371c8 btrfs-progs: tests: misc/030: do not require v1 cache for the test case
[PROBLEM]
Since we have migrated to default v2 cache, the test case
misc/030-missing-device-image is no longer executed:

    [TEST/misc]   030-missing-device-image
    [NOTRUN] unable to create v1 space cache

[CAUSE]
The test case itself is trying its best to cover all paths, including
the data extent read path.

Thus the test case is requiring v1 cache, as that's the only way to
cover the data read path.

[FIX]
Just remove the v1 space cache requirement, it's still better to run the
test even it only exercises the metadata read path.

The good news is, after commit 3ff9d35257 ("btrfs-progs: use
read_data_from_disk() to replace read_extent_from_disk() and replace
read_extent_data()"), all data/metadata read paths are unified.
They only difference is the verification part.

Thus even if we didn't fully exercise the data read path, we didn't lose
much coverage anyway.

b51117d68e btrfs-progs: tests: check for btrfs ACL support
Fix failures caused by the lack of ACL support in btrfs. For example:

  $ make test
    ::
    [TEST/misc]   057-btrfstune-free-space-tree
    failed: setfacl -m u:root:x /Volumes/ws/btrfs-progs/tests/mnt/acls/acls.1
    test failed for case 057-btrfstune-free-space-tree
    make: *** [Makefile:493: test-misc] Error 1

Similar failures occurred in the test cases convert/001-ext2-basic,
convert/003-ext4-basic, convert/005-delete-all-rollback, and
convert/006-large-hole-extent.

Resolve it by adding a check for ACL support using the
check_kernel_support_acl() helper function. It gracefully handles the case
when ACL support is not compiled by calling _not_run().

788e30f7ea btrfs-progs: tests: fix failure of misc/034
[BUG]
Test case misc/034 can fail like this:

  ====== RUN CHECK mount /dev/loop16 /home/adam/btrfs-progs/tests/mnt
  mount: /home/adam/btrfs-progs/tests/mnt: wrong fs type, bad option, bad superblock on /dev/loop16, missing codepage or helper program, or other error.
         dmesg(1) may have more information after failed mount system call.
  failed: mount /dev/loop16 /home/adam/btrfs-progs/tests/mnt

And the dmesg looks like this:

  loop16: detected capacity change from 0 to 1024000
  loop17: detected capacity change from 0 to 1024000
  BTRFS: device fsid 593e23af-a7e6-4360-b16a-229f415de697 devid 1 transid 6 /dev/loop16 scanned by mount (79348)
  BTRFS info (device loop16): using crc32c (crc32c-intel) checksum algorithm
  BTRFS info (device loop16): found metadata UUID change in progress flag, clearing
  BTRFS info (device loop16): disk space caching is enabled
  BTRFS error (device loop16): devid 2 uuid cde07de6-db7e-4b34-909e-d3db6e7c0b06 is missing
  BTRFS error (device loop16): failed to read the system array: -2
  BTRFS error (device loop16): open_ctree failed

[CAUSE]
From the dmesg, it shows that although both loopback devices are
properly registered, only one is properly scanned by mount.

Thus the other device is missing, and without "-o degraded" the
filesystem failed to be mounted.

[FIX]
Before we mount the filesystem, also scan them in their passed order
to properly assemble the device list for mount.

create btrfs.

Since the v0 root item is already deprecated for a long time, newly

subvolume list -u" should always report the correct uuid.

The test case relies on external program "uuidparse" which should be
provided by util-linux.

dca6b12f0a btrfs-progs: fix read-write subvol and received_uuid flags check
There's a report that a read-only subvolume with a received_uuid set
emits the warning in command 'btrfs subvolume show', which is obviously
wrong.

The reason is that there are different types of root item flags,
depending on how we read them. The check in cmd_subvol_show uses the
ioctl GET_SUBVOL_INFO and the appropriate flag is raw
BTRFS_ROOT_SUBVOL_RDONLY (0x1), while there's another SUBVOL_GETFLAGS that
maps the flags and the raw value is different (BTRFS_SUBVOL_RDONLY, 0x2).

Due to this the warning was issued. Fix that by using the right flag
constant. The test has been extended to check for all combinations of
read-write and received_uuid.

db8c9a420c btrfs-progs: tests: make misc/038 more robust when searching backup slots
Test case misc/038 uses hard coded backup slot number, this means if we
change how many transactions we commit during mkfs, it will immediately
break the tests.

Such hard coded tests will be a big pain for later btrfs-progs updates.

Update it with runtime backup slot search.

Such search is done by using current filesystem generation as a search
target and grab the slot number.

By this, no matter how many transactions we commit during mkfs, the test
case should be able to handle it.

feb8f56ba2 btrfs-progs: receive: fix btrfs_mount_root substring bug
The current mount detection code in btrfs receive is not quite perfect.
For example, suppose /tmp is mounted as a tmpfs. In that case,
btrfs receive /tmp2 will find /tmp as the longest mount that matches a
prefix of /tmp2 and blow up because it is not a btrfs filesystem, even
if /tmp2 is just a directory in / mounted as btrfs.

Fix this by replacing the substring check with a dirname recursion to
only check the directories in the path of the dir, rather than every
substring.

Add a new test for this case.

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.

6ec6c11ba1 btrfs-progs: tests: misc: find-root and select-super are internal commands
Enhance the prerequisite check for internal tools, up to now missing
btrfs-find-root and btrfs-select-super. The correct path in the checks
is INTERNAL_BIN.

The testsuite is now self-contained.

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.
