crypto: talitos - fix max key size for sha384 and sha512

2021-09-26T11:36:17Z

commit 192125ed5ce62afba24312d8e7a0314577565b4a upstream. Below commit came with a typo in the CONFIG_ symbol, leading to a permanently reduced max key size regarless of the driver capabilities.

crypto: talitos - reduce max key size for SEC1

2021-09-22T09:42:57Z

commit b8fbdc2bc4e71b62646031d5df5f08aafe15d5ad upstream. SEC1 doesn't support SHA384/512, so it doesn't require longer keys. This patch reduces the max key size when the driver is built for SEC1 only.

crypto: talitos - Fix return type of current_desc_hdr()

2020-12-29T12:44:53Z

[ Upstream commit 0237616173fd363a54bd272aa3bd376faa1d7caa ] current_desc_hdr() returns a u32 but in fact this is a __be32, leading to a lot of sparse warnings. Change the return type to __be32 and ensure it is handled as sure by the caller.

crypto: talitos - Do not modify req->cryptlen on decryption.

2019-09-21T05:14:07Z

commit 7ede4c36cf7c6516986ee9d75b197c8bf73ea96f upstream. For decrypt, req->cryptlen includes the size of the authentication part while all functions of the driver expect cryptlen to be the size of the encrypted data. As it is not expected to change req->cryptlen, this patch implements local calculation of cryptlen.

crypto: talitos - check data blocksize in ablkcipher.

2019-09-21T05:14:07Z

commit ee483d32ee1a1a7f7d7e918fbc350c790a5af64a upstream. When data size is not a multiple of the alg's block size, the SEC generates an error interrupt and dumps the registers. And for NULL size, the SEC does just nothing and the interrupt is awaited forever. This patch ensures the data size is correct before submitting the request to the SEC engine.
