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.

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: 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

ubifs-utils: Add linux hexdump implementations lib

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

Add linux hexdump implementations lib, because function print_hex_dump() is 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

ubifs-utils: Add implementations for linux kernel printing functions

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

Add implementations for linux kernel printing functions, because these functions(eg. pr_debug, pr_err, etc.) are widely used in UBIFS linux kernel libs. No need to define multiple levels in dbg_msg for debuging, just replace dbg_msg with pr_debug. Now, there are five levels of printing messages: 0 - none 1 - error message 2 - warning message [default] 3 - notice message 4 - debug message This is a preparation for replacing implementation of UBIFS utils with linux kernel libs.

ubifs-utils: Add bit operations implementations

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

Add bit operations implementations, because there are some bit operations (eg. __set_bit, test_bit) 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

ubifs-utils: Add linux type definitions

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

Add linux type definitions, because there are many types (eg. u8/u16/u64) used in UBIFS linux kernel libs. Besides move type conversions (eg. cpu_to_le16, cpu_to_le32, etc.) into type definitions header file. This is a preparation for replacing implementation of UBIFS utils with linux kernel libs.

ubifs-utils: Move 'debug_level' into ubifs_info structure

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

Embed new member 'debug_level' into 'ubifs_info' structure, then global variable 'debug_level' can be removed from mkfs.ubifs.c. Next patches will import UBIFS libs from linux kernel, which could print messages with different levels, then 'debug_level' can be used to control which level messages should be printed.

ubifs-utils: Clean up error message printing functions

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

Functions 'err_msg' and 'sys_err_msg' are almost same with 'errmsg' and 'sys_errmsg', since 'errmsg' and 'sys_errmsg' can print programe name, so replace error message printing functions (ubifs-utils) with common lib functions(include/common.h).
