of/reconfig: Always use the same structure for notifiers

2014-11-24T22:25:03+00:00

The OF_RECONFIG notifier callback uses a different structure depending
on whether it is a node change or a property change. This is silly, and
not very safe. Rework the code to use the same data structure regardless
of the type of notifier.

crypto: nx - Fixing the limit number of bytes to be processed

2014-11-06T15:15:03+00:00

The previous limits were estimated locally in a single step
basead on bound values, however it was not correct since
when given certain scatterlist the function nx_build_sg_lists
was consuming more sg entries than allocated causing a
memory corruption and crashes.

e.g.: in the worst case we could have one sg entry for a single byte.

This patch fixes it modifying the logic of the bound limit
moving it to nx_sg_build_lists and set a correct sg_max limit,
adding a trim function to ensure the bound in sg_list. Also fixing
nx_build_sg_list  NULL and untreated return in case of overflow.

crypto: nx - Fix SHA concurrence issue and sg limit bounds

2014-11-06T15:15:02+00:00

NX SHA algorithms stores the message digest into tfm what
cause a concurrence issue where hashes may be replaced by others.
This patch cleans up the cases where it's handling unnecessarily shared
variables in nx context and copies the current msg digest to a sctx->state
in order to safetly handle with the hashe's state.

Also fixes and does some clean ups regarding the right sg max limit
and bounds to the sg list avoind a memory crash.

crypto: nx - Moving limit and bound logic in CTR and fix IV vector

2014-11-06T15:15:01+00:00

The previous limits were estimated locally in a single step
basead on bound values, however it was not correct since
when given certain scatterlist the function nx_build_sg_lists
was consuming more sg entries than allocated causing a
memory corruption and crashes.

- This patch removes the old logic and replaces it into nx_sg_build_lists
in order to build a correct nx_sg list using the correct sg_max limit
and bounds.

IV vector was not set correctly to zero causing ctr crash in tcrypt tests.

- Fixed setting IV vector  bits to zero.
