crypto: caam - Pad SG length when allocating hash edesc

2024-10-04T14:33:14Z

[ Upstream commit 5124bc96162667766f6120b19f57a640c2eccb2a ] Because hardware will read in multiples of 4 SG entries, ensure the allocated length is always padded. This was already done by some callers of ahash_edesc_alloc, but ahash_digest was conspicuously missing. In any case, doing it in the allocation function ensures that the memory is always there.

crypto: caam - fix asynchronous hash

2024-01-26T08:35:55Z

ahash_alg->setkey is updated to ahash_nosetkey in ahash.c so checking setkey() function to determine hmac algorithm is not valid. to fix this added is_hmac variable in structure caam_hash_alg to determine whether the algorithm is hmac or not.

crypto: caam - Use new crypto_engine_op interface

2023-08-18T09:01:10Z

Use the new crypto_engine_op interface where the callback is stored in the algorithm object. Signed-off-by: Herbert Xu

crypto: caam - Include internal/engine.h

2023-08-18T09:01:10Z

Inlucde internal/engine.h because this driver uses directly accesses attributes inside struct crypto_engine. Signed-off-by: Herbert Xu

crypto: caam - Remove messages related to memory allocation failure

2023-07-28T10:20:25Z

On memory allocation failure, the function calling stack is already logged. So there is no need to explicitly log an extra message. Remove them, ans simplify some code accordingly. Signed-off-by: Christophe JAILLET Reviewed-by: Gaurav Jain Signed-off-by: Herbert Xu

crypto: caam - Use struct_size()

2023-07-28T10:20:25Z

Use struct_size() instead of hand-writing it, when allocating a structure with a flex array. This is less verbose, more robust and more informative. Signed-off-by: Christophe JAILLET Reviewed-by: Gaurav Jain Signed-off-by: Herbert Xu

crypto: caam - reduce page 0 regs access to minimum

2023-04-14T10:59:34Z

Use job ring register map, in place of controller register map to access page 0 registers, as access to the controller register map is not permitted.

crypto: caam - Use ahash_request_complete

2023-01-27T10:58:09Z

Instead of calling the base completion function directly, use the correct ahash helper which is ahash_request_complete. Signed-off-by: Herbert Xu Reviewed-by: Gaurav Jain Signed-off-by: Herbert Xu

crypto: caam - Remove GFP_DMA and add DMA alignment padding

2023-01-06T09:15:47Z

GFP_DMA does not guarantee that the returned memory is aligned for DMA. It should be removed where it is superfluous. However, kmalloc may start returning DMA-unaligned memory in future so fix this by adding the alignment by hand. Signed-off-by: Herbert Xu

crypto: caam - Set DMA alignment explicitly

2022-12-02T10:12:41Z

This driver has been implicitly relying on kmalloc alignment to be sufficient for DMA. This may no longer be the case with upcoming arm64 changes. This patch changes it to explicitly request DMA alignment from the Crypto API. Signed-off-by: Herbert Xu
