ubifs: authentication: Authenticate LPT

2018-10-23T11:48:47+00:00

The LPT needs to be authenticated aswell. Since the LPT is only written during commit it is enough to authenticate the whole LPT with a single hash which is stored in the master node. Only the leaf nodes (pnodes) are hashed which makes the implementation much simpler than it would be to hash the complete LPT. Signed-off-by: Sascha Hauer Signed-off-by: Richard Weinberger

ubifs: Export pnode_lookup as ubifs_pnode_lookup

2018-10-23T11:48:17+00:00

ubifs_lpt_lookup could be implemented using pnode_lookup. To make that possible move pnode_lookup from lpt.c to lpt_commit.c. Rename it to ubifs_pnode_lookup since it's now exported. Signed-off-by: Sascha Hauer Signed-off-by: Richard Weinberger

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: lpt: Fix wrong pnode number range in comment

2018-06-07T13:53:15+00:00

The comment above pnode_lookup claims the range for the pnode number is from 0 to main_lebs - 1. This is wrong because every pnode has informations about UBIFS_LPT_FANOUT LEBs, thus the corrent range is 0 to to (main_lebs - 1) / UBIFS_LPT_FANOUT.

UBIFS: improve function-level documentation

2016-10-02T20:55:02+00:00

Fix various inconsistencies in the documentation associated with various functions. In the case of fs/ubifs/lprops.c, the second parameter of ubifs_get_lp_stats was renamed from st to lst in commit 84abf972ccff ("UBIFS: add re-mount debugging checks") In the case of fs/ubifs/lpt_commit.c, the excess variables have never existed in the associated functions since the code was introduced into the kernel. The others appear to be straightforward typos. Issues detected using Coccinelle (http://coccinelle.lip6.fr/) Signed-off-by: Julia Lawall Signed-off-by: Richard Weinberger

UBIFS: extend debug/message capabilities

2015-03-25T09:08:41+00:00

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. The output looks like, [ 95.444879] UBIFS (ubi0:1): background thread "ubifs_bgt0_1" started, PID 696 [ 95.484688] UBIFS (ubi0:1): UBIFS: mounted UBI device 0, volume 1, name "test1" [ 95.484694] UBIFS (ubi0:1): LEB size: 126976 bytes (124 KiB), min./max.
