7 daysfsck.ubifs: Add node parsing functionsZhihao Cheng
Add parsing functions for each type of nodes, which will be used for checking the validity of raw node data while reading from TNC or scanning from UBIFS logical erase block. Signed-off-by: Zhihao Cheng <chengzhihao1@huawei.com> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
7 daysfsck.ubifs: Load filesystem information from UBI volumeZhihao Cheng
Load filesystem information from UBI volume (Similar to UBIFS mounting process), initialize kinds of buffers and read superblock. This is the base step for both fsck and rebuild_fs. Subsequent pacthes will complete this step by adding more steps(eg. read master, replay journal, etc.) which are only used in fsck.

7 daysfsck.ubifs: Distinguish reasons when certain failures happenZhihao Cheng
Read failure caused by scanning corrupted data or invalid data members should be identified, because fsck can handle it. Updating lp failure caused by bad space statistics should be identified too, because fsck can handle it. Add eight callback functions to implement it for fsck: 1. set_failure_reason_callback: Record failure reasons when reading or parsing node failed, there are four reasons: a. FR_DATA_CORRUPTED: scanning corrupted data or invalid nodes found b. FR_TNC_CORRUPTED: invalid index nodes c. FR_LPT_CORRUPTED: invalid pnode/nnode d. FR_LPT_INCORRECT: invalid space statistics or invalid LEB properties 2. get_failure_reason_callback: get failure reasons 3. clear_failure_reason_callback: Clear the error which is caused by above reasons. 4. test_and_clear_failure_reason_callback: Check and clear the error which is caused by above reasons, if so, fsck will handle it according to specific situation. For example, fsck will drop data node rather than fails to return when reading failure is caused by DATA_CORRUPTED. For another example, journal replaying will continue rather than fails to return if updating lpt failure is caused by LPT_CORRUPTED. 5. set_lpt_invalid_callback: Set the invalid lpt status 6. test_lpt_valid_callback: Check whether the lpt is corrupted/incorrect, it should be invoked before updating lp, if lpt status is invalid, returns false (which means that caller should skip updating lp, because updating lp could trigger assertion failed in ubifs_change_lp). 7. can_ignore_failure_callback: Check whether the failure can be ignored, some inconsistent errors won't affect the fsck process, for example wrong space statistics can be fixed after traversing TNC, so failures caused by incorrect space statistics can be ignored. 8. handle_failure_callback: Check whether the failure can be handled, some inconsistent errors could be fixed by fsck, we have fix_problem to do that, but UBIFS needs a callback function to invoke it in common libs.

7 daysfsck.ubifs: Add inconsistent problem handling asking functionZhihao Cheng
There are four dimensions to define the type of inconsistent problems: 1. fixable: Some inconsistent problems can't be fixed, for example corrupted superblock. Un-fixable problem will abort program. 2. must fix: Some inconsistent problems can be ignored(eg. incorrect isize), but some are not(eg. corrupted TNC), which will affect the subsequent fsck steps. 3. drop data: Some fixing methods will drop user data, which is unacceptable for safe mode. If it happens, fsck will be aborted. 4. need rebuild: Some inconsistent problems depends on rebuilding filesystem to be fixed(eg. corrupted master node, corrupted TNC). Define an asking function to handle above kinds of inconsistent problems. Signed-off-by: Zhihao Cheng <chengzhihao1@huawei.com> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
7 daysfsck.ubifs: Add fsck supportZhihao Cheng
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.
