fsck.ubifs: check and correct the space statistics

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

This is the 12/18 step of fsck. Check and correct the space statistics. There could be following steps and possible errors: Step 1. Exit for check mode, if %FR_LPT_CORRUPTED or %FR_LPT_INCORRECT is set in lpt status, the exit code should have %FSCK_UNCORRECTED. Step 2. Check lpt status, if %FR_LPT_CORRUPTED is set in lpt status, normal mode with 'no' answer will exit, other modes will rebuild lpt. Step 3. Traverse LPT nodes, check the correctness of nnode and pnode, compare LEB scanning result with LEB properties. a. LPT node is corrupted, normal mode with 'no' answer will exit, rebuild lpt for other modes. b. Incorrect nnode/pnode, normal mode with 'no' answer will exit, other other modes will correct the nnode/pnode. c. Inconsistent comparing result, normal mode with 'no' answer will exit, other modes will correct the space statistics. Step 4. Check and correct the lprops table information. Step 5. Set gc lnum(ubifs_rcvry_gc_commit / take_gc_lnum). Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

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 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 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: Extract UBI opening/closing/volume_check_empty functions into a new source file

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

Move UBI opening/closing/volume_check_empty functions into common/super.c. These functions will be used in fsck. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

ubifs-utils: Add 'dev_fd' and 'libubi' into 'ubifs_info' structure

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

Embed new members 'dev_fd' and 'libubi' into ubifs_info structure, so that global variable 'ubi', 'out_fd' and 'out_ubi' could be removed from mkfs.ubifs.c. Besides, add parameter in check_volume_empty(). Next patch will extract UBI opening/closing/check_volume_empty functions into a new source file, these functions will be used in fsck.

ubifs-utils: Add 'dev_name' into 'ubifs_info' structure

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

Embed new member 'dev_name' into 'ubifs_info' structure, then global variable 'output' can be removed from mkfs.ubifs.c. Next patches will import UBIFS libs from linux kernel, which could print messages that contain device information, so this patch can distinguish different devices according to messages.

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).

ubifs-utils: Define PROGRAM_NAME as variable

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

PROGRAM_NAME is defined as a const string "mkfs.ubifs", which won't be suitable for fsck.ubifs. Add 'program_name' member in ubifs_info structure, define PROGRAM_NAME as ubifs_info.program_name. Then, error messages will display right program name if fsck.ubifs is supported. Besides, add 'program_type' member in ubifs_info structure to identify which current program type is, without comparing program name. Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer
