ubifs: Rework ubifs_assert()

2018-08-14T22:25:21+00:00

With having access to struct ubifs_info in ubifs_assert() we can give more information when an assert is failing. By using ubifs_err() we can tell which UBIFS instance failed. Also multiple actions can be taken now. We support: - report: This is what UBIFS did so far, just report the failure and go on. - read-only: Switch to read-only mode. - panic: shoot the kernel in the head.

ubifs: Pass struct ubifs_info to ubifs_assert()

2018-08-14T22:25:21+00:00

This allows us to have more context in ubifs_assert() and take different actions depending on the configuration. Signed-off-by: Richard Weinberger

UBIFS: print less

2012-08-31T14:32:58+00:00

UBIFS currently prints a lot of information when it mounts a volume, which bothers some people. Make it less chatty - print only important information by default. Get rid of 'dbg_msg()' macro completely. Reported-by: Uwe Kleine-König Signed-off-by: Artem Bityutskiy

UBIFS: use pr_ helper instead of printk

2012-08-31T14:32:57+00:00

Use 'pr_err()' instead of 'printk(KERN_ERR', etc. Signed-off-by: Artem Bityutskiy

UBIFS: fix complaints about too small debug buffer size

2012-08-22T08:51:33+00:00

When debugging is enabled, we use a temporary on-stack buffer for formatting the key strings like "(11368871, direntry, 0xcd0750)". The buffer size is 32 bytes and sometimes it is not enough to fit the key string - e.g., when inode numbers are high. This is not fatal, but the key strings are incomplete and UBIFS complains like this: UBIFS assert failed in dbg_snprintf_key at 137 (pid 1) This is a regression caused by "515315a UBIFS: fix key printing". Fix the issue by increasing the buffer to 48 bytes. Reported-by: Michael Hench Signed-off-by: Artem Bityutskiy Tested-by: Michael Hench Cc: stable@vger.kernel.org [v3.3+]

UBIFS: add debugfs knob to switch to R/O mode

2012-07-20T07:27:25+00:00

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.

UBI: Kill data type hint

2012-05-20T17:25:59+00:00

We do not need this feature and to our shame it even was not working and there was a bug found very recently. -- Artem Bityutskiy Without the data type hint UBI2 (fastmap) will be easier to implement. Signed-off-by: Richard Weinberger Signed-off-by: Artem Bityutskiy

UBIFS: get rid of dbg_err

2012-05-16T17:11:23+00:00

This patch removes the 'dbg_err()' macro and we now use 'ubifs_err()' instead. The idea of 'dbg_err()' was to compile out some error message to make the binary a bit smaller - but I think it was a bad idea. Signed-off-by: Artem Bityutskiy
