ubifs: Fix assertion in layout_in_gaps()

2016-09-01T02:05:44+00:00

[ Upstream commit c0082e985fdf77b02fc9e0dac3b58504dcf11b7a ] An assertion in layout_in_gaps() verifies that the gap_lebs pointer is below the maximum bound. When computing this maximum bound the idx_lebs count is multiplied by sizeof(int), while C pointers arithmetic does take into account the size of the pointed elements implicitly already. Remove the multiplication to fix the assertion.

UBIFS: rename random32() to prandom_u32()

2013-01-15T13:45:27+00:00

Use more preferable function name which implies using a pseudo-random number generator. Signed-off-by: Akinobu Mita Signed-off-by: Artem Bityutskiy

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: remove Kconfig debugging option

2012-05-16T16:53:46+00:00

Have the debugging stuff always compiled-in instead. It simplifies maintanance a lot. Signed-off-by: Artem Bityutskiy

UBIFS: rename dumping functions

2012-05-16T16:15:56+00:00

This commit re-names all functions which dump something from "dbg_dump_*()" to "ubifs_dump_*()". This is done for consistency with UBI and because this way it will be more logical once we remove the debugging sompilation option. Signed-off-by: Artem Bityutskiy

UBIFS: lessen amount of debugging check types

2011-07-04T07:54:28+00:00

We have too many different debugging checks - lessen the amount by merging all index-related checks into one. At the same time, move the "force in-the-gap" test to the "index checks" class, because it is too heavy for the "general" class. This patch merges TNC, Old index, and Index size check and calles this just "index checks". Signed-off-by: Artem Bityutskiy

UBIFS: introduce helper functions for debugging checks and tests

2011-07-04T07:54:28+00:00

This patch introduces helper functions for all debugging checks, so instead of doing if (!(ubifs_chk_flags & UBIFS_CHK_GEN)) we now do if (!dbg_is_chk_gen(c)) This is a preparation to further changes where the flags will go away, and we'll need to only change the helper functions, but the code which utilizes them won't be touched. At the same time this patch removes 'dbg_force_in_the_gaps()', 'dbg_force_in_the_gaps_enabled()', and dbg_failure_mode helpers for consistency. Signed-off-by: Artem Bityutskiy

UBIFS: add few commentaries about TNC

2011-07-04T07:54:27+00:00

Add a couple of comments - while looking into TNC I could not easily figure out few facts, so it is a good idea to document them in the code. Signed-off-by: Artem Bityutskiy
