Old convert codes uses both 0400 permission and INODE_READONLY flag to

While new convert treat the inode just as normal inode, with no special

can be parsed from 'btrfs filesystem show' and 'btrfs filesystem usage',
works as the minimum size, but sometimes it does not, namely when device
extents have to relocated to holes (unallocated space) within the new
size of the device (the total allocated space sum).

Although fsck-test/012 uses sudo, it uses 'sudo -n', which won't prompt
user to input password and will return 1 if no valid credential is

And this makes test result quite annoying since it fails to mount and
still continue, which will always fail.
This patch will check 'sudo -v -n' and 'sudo -n true' to determine
whether sudo works fine in different version/settings, since in some
setting/version, 'sudo -v -n' will fail even the user is set NOPASSWD.
Also, remove the 'have_root_helper' variant, since there is a
possibility that sudo credential will timeout during the test and
'have_root_helper' won't help to detect such problem.

Previously we used to just set FULL_BACKREF if we couldn't lookup an extent info
for an extent. Now we just bail out if we can't lookup the extent info, which
is less than good since fsck is supposed to fix these very problems. So instead
figure out the flag we are supposed to use and pass that along instead. This
patch also provides a test image to test this functionality. Thanks,

Most of the checks run fine without root, but some of them may need to
do a mount test or access the data. Add the support to selectively run
commands under root, hardcoded to sudo for now.

Move leaf-corruption type no extent data case to its dir, and add
verification script in test.sh
The verification script is based on manual btrfs-debug-tree check.
The image can also be reused to other leaf-corruption type, like
corrupted leaf contains regular file extent data case.

Change the old btrfsck test infrastructure (btrfs-image dump or xz raw
dump) to the new test infrastructure.
1) Test case layout
The new infrastructure is dir based, each dir is one test type, and can
contain multiple images/scripts for different corner cases.
So layout will be the following:
btrfs-progs
|-tests
|-fsck-tests
|-001-SOME-CORRUPT-TYPE
|-IMAGE-FOR-CASE1
|-IMAGE-FOR-CASE2
2) Test case image types
Only 2 types for test case images.
a) btrfs-image dump
This one is the simplest case, one only needs to add the image to
corresponding dir.
b) custom script
This one is for all the resting cases which can't fit btrfs-image,
like csum error or script can generate the image (this reduces the
size obviously and good for review)
The old binary dump also belongs to this type, so need to add script
to extract them.

This adds two new test images
1) 008-bad-offset-snapshots. This has a corrupt item with multiple snapshots
pointing to it, to make sure the bad block repair stuff doesn't loop and
actually repairs stuff. It also requires the dir index repair stuff to pass our
built in tests which is why it's not tied to the same commit.
2) 009-bad-dir-index-name.img. This has a corrupt name in a dir index to make
sure our dir index repair stuff is working properly.

This change adds code to detect and fix the issue introduced in the kernel
release 3.17, where creation of read-only snapshots lead to a corrupted
filesystem if they were created at a moment when the source subvolume/snapshot
had orphan items. The issue was that the on-disk root items became incorrect,
referring to the pre orphan cleanup root node instead of the post orphan
cleanup root node.
A test filesystem can be generated with the test case recently submitted for
xfstests/fstests, which is essencially the following (bash script):
workout()
{
ops=$1
procs=$2
num_snapshots=$3
_scratch_mkfs >> $seqres.full 2>&1
_scratch_mount
snapshot_cmd="$BTRFS_UTIL_PROG subvolume snapshot -r $SCRATCH_MNT"
snapshot_cmd="$snapshot_cmd $SCRATCH_MNT/snap_\`date +'%H_%M_%S_%N'\`"
run_check $FSSTRESS_PROG -p $procs \
-x "$snapshot_cmd" -X $num_snapshots -d $SCRATCH_MNT -n $ops
}
ops=10000
procs=4
snapshots=500
workout $ops $procs $snapshots

We can deal with corrupt items by deleting them in a few cases. Fsck can easily
recover from a missing extent item or a dir index item. So if we notice a item
is completely bogus and it is of a key that we know we can repair then just
delete it and carry on. Thanks,

A user had a corrupted fs where the items had been shifted improperly. This
patch adds the ability to fix this sort of problem within fsck. We will simply
shift the item over to the proper offset and update the offsets to make sure
they are correct. I tested this with a hand crafted fs that was broken in the
same way as the user, and I've included the file as a new test. Thanks,

If we have an inode backref entry then we know enough to add back a missing dir
index. When messing with the inode backrefs we need to do all of that first
before we process the inode recs themselves as we may clear errors on the inode
recs as we fix the directory indexes. This adds the framework for fixing
backref errors and fixes missing dir index issues. Thanks,
