Improve check for GCC compiler version

2025-06-02T05:27:40+00:00

When using unreleased compiler has version like 15.0.1 and that test fails because __GNUC_MINOR__ < 1 becomes true, therefore check for full version string which is more rubust. Signed-off-by: Khem Raj Signed-off-by: David Oberhollenzer

ubifs-utils: common: fix memory leak in devtable.c

2025-06-02T05:23:41+00:00

Report of the static analyzer: Dynamic memory, referenced by 'line', is allocated at devtable.c:356 by calling function 'getline' and lost at devtable.c:388. (line: while (getline(&line, &len, f) != -1) {) Correct explained: Now line is freed in any exit scenario via out_close which eliminates this error. Triggers found by static analyzer Svace.

ubifs-utils: link libmissing.a in case execinfo.h isn't present

2025-06-02T05:22:10+00:00

On musl execinfo.h doesn't exist, but ubifs-utils uses backtrace() when reporting errors. This results in build failures under musl. Handily, libmissing.a already exists with a stub implementation of backtrace(). Guard the execinfo.h include and if it isn't available instead include libmissing.h, and link to libmissing.a to provide backtrace() if needed.

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

2025-01-30T17:30:16+00:00

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: 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: Add fsck support

2024-11-11T09:32:45+00:00

Add basic process code for fsck.ubifs. There are following modes for fsck: 1. normal mode: Check the filesystem, ask user whether or not to fix the problem as long as inconsistent data is found during fs checking. 2. safe mode: Check and safely repair the filesystem, if there are any data dropping operations needed by fixing, fsck will fail. 3. danger mode: Answer 'yes' to all questions. There two sub modes: a) Check and repair the filesystem according to TNC, data dropping will be reported. If TNC/master/log is corrupted, fsck will fail. b) Check and forcedly repair the filesystem according to TNC, turns to rebuild filesystem if TNC/master/log is corrupted. Always make fsck succeed. 4. check mode: Make no changes to the filesystem, only check the filesystem. 5. rebuild mode: Scan entire UBI volume to find all nodes, and rebuild filesystem, always make fsck success.

ubifs-utils: Replace ubifs related source code with linux kernel implementation

2024-11-11T09:32:45+00:00

Replace ubifs related source code with the implementation of linux kernel. It makes userspace implementation be same with linux kernel, then fsck.ubifs can resuse the code. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

ubifs-utils: Move ubifs-media.h in libubifs

2024-11-11T09:32:45+00:00

Since ubifs-media.h is only used for ubifs-utils, move it under ubifs-utils/libubifs. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

ubifs-utils: Add descriptions for new lib files in common/README

2024-11-11T09:32:45+00:00

There are several new libs(eg. atomic, kmem, bitops. etc.) have been imported into ubifs-utils, add descriptions for these libs in README. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

ubifs-utils: Add common definitions in linux kernel

2024-11-11T09:32:45+00:00

Add common definitions in linux kernel, which are used in UBIFS linux kernel libs. This is a preparation for replacing implementation of UBIFS utils with linux kernel libs. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer
