tests: ubifs_tools: fsck_tests: Add corrupted images
This is a preparation for adding bad images fsck testcase. There is
no debugfs tools (for example: debugfs[ext4], xfs_db) for UBIFS, so
there is no way to inject precise corruption into UBIFS image, we have
to prepare inconsistent UBIFS images in advance like e2fsprogs[1] does.
(Goto [2] to see how to generate inconsistent UBIFS images).
Original UBIFS image content:
/
├── corrupt_file (xattr - user.corrupt:123, 2K data)
├── dir
│ ├── block_dev
│ ├── char_dev
│ ├── dir
│ └── file (content: '123')
├── hardl_corrupt_file => corrupt_file
└── softl_corrupt_file -> corrupt_file
Here's a descriptons of the various testing images:
