crypto: sun4i-ss - use DEFINE_SHOW_ATTRIBUTE to simplify sun4i_ss_debugfs

2022-09-24T08:14:44Z

Use DEFINE_SHOW_ATTRIBUTE helper macro to simplify the code. Signed-off-by: Liu Shixin Acked-by: Corentin Labbe Tested-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: sun4i-ss - do not allocate backup IV on requests

2022-05-13T09:24:17Z

Instead of allocate memory on each requests, it is easier to pre-allocate buffer for backup IV. This made error path easier. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: sun4i-ss - Fix PM reference leak when pm_runtime_get_sync() fails

2021-04-16T11:16:32Z

pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. Fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced. Signed-off-by: Shixin Liu Signed-off-by: Herbert Xu

crypto: sun4i-ss - simplify optional reset handling

2021-03-12T13:04:07Z

As of commit bb475230b8e5 ("reset: make optional functions really optional"), the reset framework API calls use NULL pointers to describe optional, non-present reset controls. This allows to unconditionally return errors from devm_reset_control_get_optional_exclusive. Signed-off-by: Philipp Zabel Signed-off-by: Herbert Xu

crypto: sun4i-ss - add SPDX header and remove blank lines

crypto: sun4i-ss - enabled stats via debugfs

crypto: sun4i-ss - fix kmap usage

2021-01-02T21:41:36Z

With the recent kmap change, some tests which were conditional on CONFIG_DEBUG_HIGHMEM now are enabled by default. This permit to detect a problem in sun4i-ss usage of kmap. sun4i-ss uses two kmap via sg_miter (one for input, one for output), but using two kmap at the same time is hard: "the ordering has to be correct and with sg_miter that's probably hard to get right." (quoting Tlgx) So the easiest solution is to never have two sg_miter/kmap open at the same time. After each use of sg_miter, I store the current index, for being able to resume sg_miter to the right place.

crypto: sun4i-ss - initialize need_fallback

2021-01-02T21:41:36Z

The need_fallback is never initialized and seem to be always true at runtime. So all hardware operations are always bypassed. Fixes: 0ae1f46c55f87 ("crypto: sun4i-ss - fallback when length is not multiple of blocksize") Cc: Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: sun4i-ss - handle BigEndian for cipher

2021-01-02T21:41:35Z

Ciphers produce invalid results on BE. Key and IV need to be written in LE. Fixes: 6298e948215f2 ("crypto: sunxi-ss - Add Allwinner Security System crypto accelerator") Cc: Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: sun4i-ss - IV register does not work on A10 and A13

2021-01-02T21:41:35Z

Allwinner A10 and A13 SoC have a version of the SS which produce invalid IV in IVx register. Instead of adding a variant for those, let's convert SS to produce IV directly from data.
