2020-12-13ubifs: ubifs_dump_node: Dump all branches of the index nodeZhihao Cheng1-1/+1
An index node can have up to c->fanout branches, all branches should be displayed while dumping index node. Signed-off-by: Zhihao Cheng <[email protected]> Signed-off-by: Richard Weinberger <[email protected]>

2020-12-13ubifs: Pass node length in all node dumping callersZhihao Cheng1-15/+15
Function ubifs_dump_node() has been modified to avoid memory oob accessing while dumping node, node length (corresponding to the size of allocated memory for node) should be passed into all node dumping callers.

2020-12-13ubifs: Limit dumping length by size of memory which is allocated for the nodeZhihao Cheng1-13/+50
To prevent memory out-of-bounds accessing in ubifs_dump_node(), actual dumping length should be restricted by another condition(size of memory which is allocated for the node). This patch handles following situations (These situations may be caused by bit flipping due to hardware error, writing bypass ubifs, unknown bugs in ubifs, etc.): 1. bad node_len: Dumping data according to 'ch->len' which may exceed the size of memory allocated for node. 2. bad node content: Some kinds of node can record additional data, eg. index node and orphan node, make sure the size of additional data not beyond the node length. 3. node_type changes: Read data according to type A, but expected type B, before that, node is allocated according to type B's size. Length of type A node is greater than type B node. Signed-off-by: Zhihao Cheng <[email protected]> Signed-off-by: Richard Weinberger <[email protected]>

2015-03-25UBIFS: extend debug/message capabilitiesSheng Yong1-93/+93
In the case where we have more than one volumes on different UBI devices, it may be not that easy to tell which volume prints the messages. Add ubi number and volume id in ubifs_msg/warn/error to help debug. These two values are passed by struct ubifs_info. For those where ubifs_info is not initialized yet, ubifs_* is replaced by pr_*. For those where ubifs_info is not avaliable, ubifs_info is passed to the calling function as a const parameter.

2012-08-31UBIFS: fix power cut emulation for mtdramArtem Bityutskiy1-9/+11
The power cut emulation did not work correctly because we corrupted more than one max. I/O unit in the buffer and then wrote the entire buffer. This lead to recovery errors because UBIFS complained about corrupted free space. And this was easily reproducible on mtdram because max. write size is very small there (64 bytes), and we could easily have a 1KiB buffer, corrupt 128 bytes there, and then write the entire buffer. The fix is to corrupt max. write size bytes at most, and write only up to the last corrupted max. write size chunk, not the entire buffer. Signed-off-by: Artem Bityutskiy <[email protected]>

This patch adds another debugfs knob which switches UBIFS to R/O mode. I needed it while trying to reproduce the 'first log node is not CS node' bug. Without this debugfs knob you have to perform a power cut to repruduce the bug. The knob is named 'ro_error' and all it does is it sets the 'ro_error' UBIFS flag which makes UBIFS disallow any further writes - even write-back will fail with -EROFS. Useful for debugging.
