there is an unexpected word 'for' in the comments that need to be dropped file - drivers/crypto/caam/caamhash_desc.c line - 25 * must be false for for ahash first and digest changed to: * must be false for ahash first and digest Signed-off-by: Jiang Jian Reviewed-by: Gaurav Jain Signed-off-by: Herbert Xu

crypto: caam - keep both virtual and dma key addresses

2019-08-09T05:11:49Z

Update alginfo struct to keep both virtual and dma key addresses, so that descriptors have them at hand. One example where this is needed is in the xcbc(aes) shared descriptors, which are updated in current patch. Another example is the upcoming fix for DKP.

crypto: caam - add support for cmac(aes)

2019-02-01T06:42:03Z

Add cmac(aes) keyed hash offloading support. Similar to xcbc implementation, driver must make sure there are still some bytes buffered when ahash_final() is called. This way HW is able to decide whether padding is needed and which key to derive (L -> K1 / K2) for the last block. Signed-off-by: Iuliana Prodan Signed-off-by: Horia Geantă Signed-off-by: Herbert Xu

crypto: caam - add support for xcbc(aes)

2019-01-11T06:16:56Z

Add xcbc(aes) offloading support. Due to xcbc algorithm design and HW implementation in CAAM, driver must still have some bytes to send to the crypto engine when ahash_final() is called - such that HW correctly uses either K2 or K3 for the last block.

crypto: caam - export ahash shared descriptor generation

2018-09-21T05:24:51Z

caam/qi2 driver will support ahash algorithms, thus move ahash descriptors generation in a shared location. Signed-off-by: Horia Geantă Signed-off-by: Herbert Xu
