Subject: [PATCH v2 00/12] crypto: caam - xts(aes) updates
Date: Mon, 21 Sep 2020 10:31:53 +0300 [thread overview]
Message-ID: <20200921073205.24742-1-andrei.botila@oss.nxp.com> (raw)
From: Andrei Botila <andrei.botila@nxp.com>
This patch series fixes some problems in CAAM's implementation of xts(aes):
- CAAM until Era 9 can't process XTS with 16B IV
- CAAM can only process in hardware XTS key lengths of 16B and 32B
- These hardware limitations are resolved through a fallback
- CAAM used to return 0 for XTS block length equal to zero
This patch series also adds a new feature in CAAM's xts(aes):
- CAAM is now able to process XTS with 16B IV in HW
Changes since v1:
- use only get_unaligned() for calculating XTS IV size
- fixed the double calling of crypto_skcipher_set_reqsize() in case of XTS
- added a patch which modifies the return value for XTS when block length
is equal to zero
Andrei Botila (12):
crypto: caam/jr - add fallback for XTS with more than 8B IV
crypto: caam/qi - add fallback for XTS with more than 8B IV
crypto: caam/qi2 - add fallback for XTS with more than 8B IV
crypto: caam/jr - add support for more XTS key lengths
crypto: caam/qi - add support for more XTS key lengths
crypto: caam/qi2 - add support for more XTS key lengths
crypto: caam/jr - add xts check for block length equal to zero
crypto: caam/qi - add xts check for block length equal to zero
crypto: caam/qi2 - add xts check for block length equal to zero
crypto: caam/jr - add support for XTS with 16B IV
crypto: caam/qi - add support for XTS with 16B IV
crypto: caam/qi2 - add support for XTS with 16B IV
