crypto: ccree - use correct internal state sizes for export

2019-05-22T05:38:45Z

commit f3df82b468f00cca241d96ee3697c9a5e7fb6bd0 upstream. We were computing the size of the import buffer based on the digest size but the 318 and 224 byte variants use 512 and 256 bytes internal state sizes respectfully, thus causing the import buffer to overrun. Fix it by using the right sizes. Signed-off-by: Gilad Ben-Yossef Cc: stable@vger.kernel.org # v4.19+ Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

crypto: ccree - don't map MAC key on stack

2019-05-22T05:38:45Z

commit 874e163759f27e0a9988c5d1f4605e3f25564fd2 upstream. The MAC hash key might be passed to us on stack. Copy it to a slab buffer before mapping to gurantee proper DMA mapping.

crypto: ccree - add support for CryptoCell 703

2018-12-07T06:14:59Z

Add support for Arm TrustZone CryptoCell 703. The 703 is a variant of the CryptoCell 713 that supports only algorithms certified by the Chinesse Office of the State Commercial Cryptography Administration (OSCCA). Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu

crypto: ccree - add SM3 support

2018-11-09T09:37:58Z

Add support for SM3 cipher in CryptoCell 713. Signed-off-by: Yael Chemla Signed-off-by: Herbert Xu

crypto: ccree - modify set_cipher_mode usage from cc_hash

2018-11-09T09:36:49Z

encapsulate set_cipher_mode call with another api, preparation for specific hash behavior as needed in later patches when SM3 introduced. Signed-off-by: Yael Chemla Signed-off-by: Herbert Xu

crypto: ccree - adjust hash length to suit certain context specifics

2018-11-09T09:36:49Z

Adjust hash length such that it will not be fixed and general for all algs. Instead make it suitable for certain context information. This is preparation for SM3 support. Signed-off-by: Yael Chemla Signed-off-by: Herbert Xu

crypto: ccree - fix finup

2018-07-08T16:33:35Z

finup() operation was incorrect, padding was missing. Fix by setting the ccree HW to enable padding. Signed-off-by: Hadar Gat [ gilad@benyossef.com: refactored for better code sharing ] Signed-off-by: Gilad Ben-Yossef Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu

crypto: ahash - remove useless setting of cra_type

2018-07-08T16:30:26Z

Some ahash algorithms set .cra_type = &crypto_ahash_type. But this is redundant with the C structure type ('struct ahash_alg'), and crypto_register_ahash() already sets the .cra_type automatically. Apparently the useless assignment has just been copy+pasted around. So, remove the useless assignment from all the ahash algorithms. This patch shouldn't change any actual behavior.

crypto: ahash - remove useless setting of type flags

2018-07-08T16:30:25Z

Many ahash algorithms set .cra_flags = CRYPTO_ALG_TYPE_AHASH. But this is redundant with the C structure type ('struct ahash_alg'), and crypto_register_ahash() already sets the type flag automatically, clearing any type flag that was already there. Apparently the useless assignment has just been copy+pasted around. So, remove the useless assignment from all the ahash algorithms. This patch shouldn't change any actual behavior.

crypto: ccree - add support for older HW revs

Add support for the legacy CryptoCell 630 and 710 revs. Signed-off-by: Gilad Ben-Yossef Signed-off-by: Herbert Xu
