ubifs-utils: common: Add descritpions for linux kernel resource files

Add descritpions for kernel resource files. Remove crc32 related descritpions, there is no crc32 related files imported from the linux kernel. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

ubifs-utils: Support Address-Sanitizier debug

2024-11-11T09:32:46+00:00

Add new option '--asan' for configuration to support dynamic Address-Sanitizier debugging, which could detect kinds of invalid memory accessing problems(eg. UAF, r/w OOB, etc.). Currently, only ubifs-utils(mkfs.ubifs/fsck.ubifs) is supported. Enable Address-Sanitizier debugging with configuration: ./configure --enable-asan Notice: The Address-Sanitizier will stop the program and print problems if memory problems are detected. Sometimes the memory problems come from third libs(not mtd-utils), which could stuck the testcases. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

fsck.ubifs: Add README to describe fsck

2024-11-11T09:32:46+00:00

Add documents to describe fsck, which includes introductions, designment, advantage and limitations. Signed-off-by: Zhihao Cheng Signed-off-by: Zhang Yi Signed-off-by: David Oberhollenzer

fsck.ubifs: Do final committing

2024-11-11T09:32:46+00:00

This is the 18/18 step of fsck. Do final committing, commit problem fixing modifications(which are generated since step 14) to disk, and clear %UBIFS_MST_DIRTY flag for master node. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

fsck.ubifs: Handle disconnected files

2024-11-11T09:32:46+00:00

This is the 17/18 step of fsck. Recover disconnected files into lost+found. If there is no free space left to recover the disconnected files, fsck may delete the files to make filesystem be consistent. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

fsck.ubifs: Check and create the lost+found

2024-11-11T09:32:46+00:00

This is the 16/18 step of fsck. Check whether the lost+found is existed, create a new one if it is not found. This step makes sure that disconnected file can be recovered under the lost+found. Signed-off-by: Huang Xiaojia Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

fsck.ubifs: Check and create the root dir

2024-11-11T09:32:46+00:00

This is the 15/18 step of fsck. Check whether the root dir is existed, create a new one if it is not found. This step makes sure that filesystem can be mounted successful. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

ubifs-utils: libubifs: Support some file operations

2024-11-11T09:32:46+00:00

Add some file operations, such as ubifs_lookup, ubifs_mkdir, etc., this is a preparation for recovering disconnected files or root dir in fsck. File writing operations are based on the journal subsystem, generated dirty data depends on a new commit in subsequent steps to update disk content.

fsck.ubifs: Check and correct the index size

2024-11-11T09:32:46+00:00

This is the 14/18 step of fsck. Check and correct the index size by traversing TNC just like dbg_check_idx_size does. This step should be executed after first committing, because 'c->calc_idx_sz' can be changed in 'ubifs_tnc_start_commit' and the initial value of 'c->calc_idx_sz' read from disk is untrusted.
