From 4e6f5098716ad2bf8859a1915fc0e42e69eaf88a Mon Sep 17 00:00:00 2001 From: Zhihao Cheng Date: Mon, 11 Nov 2024 17:08:25 +0800 Subject: tests: ubifs_tools: fsck_tests: Add corrupted images MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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: ========================================================================= image | Description |
