The following series adds support for XS-AES on version 5 CCPs, both 128- and 256-bit, and enhances/clarifies/simplifies some crypto layer code. Changes since v1: - rework the validation of the unit-size; move to a separate patch - expand the key buffer to accommodate 256-bit keys - use xts_check_key() in the crypto layer --- Gary R Hook (4): crypto: ccp - Add a call to xts_check_key() crypto: ccp - Enable XTS-AES-128 support on all CCPs crypto: ccp - Rework the unit-size check for XTS-AES crypto: ccp - Add XTS-AES-256 support for CCP version 5 drivers/crypto/ccp/ccp-crypto-aes-xts.c | 98 +++++++++++++++++-------------- drivers/crypto/ccp/ccp-crypto.h | 2 - drivers/crypto/ccp/ccp-dev-v5.c | 2 + drivers/crypto/ccp/ccp-dev.h | 2 + drivers/crypto/ccp/ccp-ops.c | 55 +++++++++++++++-- 5 files changed, 106 insertions(+), 53 deletions(-) --
