crypto: inside-secure - fix the sha state length in hmac_sha1_setkey

2017-08-03T05:36:11+00:00

A check is performed on the ipad/opad in the safexcel_hmac_sha1_setkey function, but the index used by the loop doing it is wrong. It is currently the size of the state array while it should be the size of a sha1 state. This patch fixes it.

crypto: inside-secure - fix invalidation check in hmac_sha1_setkey

2017-08-03T05:36:10+00:00

The safexcel_hmac_sha1_setkey function checks if an invalidation command should be issued, i.e. when the context ipad/opad change. This checks is done after filling the ipad/opad which and it can't be true. The patch fixes this by moving the check before the ipad/opad memcpy operations.

crypto: inside-secure - do not parse the dma mask from dt

2017-07-18T09:01:01+00:00

Remove the dma mask parsing from dt as this should not be encoded into the engine device tree node. Keep the fallback value for now, which should work for the boards already supported upstream. Signed-off-by: Antoine Tenart Acked-by: Arnd Bergmann Signed-off-by: Herbert Xu

crypto: inside-secure - use the base_end pointer in ring rollback

2017-06-20T03:21:48+00:00

A base_end pointer is set and provided. Use it in the ring rollback function to avoid using build-in defines. Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - increase the batch size

2017-06-20T03:21:47+00:00

Increase the batch size to the maximum number of requests a ring can handle at a time (its size). This is possible now that the request queues are per hw ring. This improves performances. Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - only dequeue when needed

2017-06-20T03:21:47+00:00

This force the need_dequeue flag to be unset whenever the dequeue function is called, to avoid calling it when it is not necessary. Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - get the backlog before dequeueing the request

2017-06-20T03:21:46+00:00

Get the backlog before dequeuing the request otherwise we'll miss the first request in line. Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - stop requeueing failed requests

2017-06-20T03:21:45+00:00

This update the dequeue function of the inside-secure safexcel driver so that failed requests aren't requeued when they fail (for whatever reason, which can be because the hw ring is full). Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - use one queue per hw ring

2017-06-20T03:21:45+00:00

Update the inside-secure safexcel driver from using one global queue to one queue per hw ring. This ease the request management and keep the hw in sync with what's done in sw. Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - update the context and request later

2017-06-20T03:21:44+00:00

This move the context and request updates at the end of the cipher and hash send() functions. This way the context and request fields are set only when everything else was successful in the send() functions. Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu
