From dcb3a4b8d7768cab59546aa2ce5dd214f7b526fe Mon Sep 17 00:00:00 2001 From: Gary R Hook Date: Tue, 25 Jul 2017 14:12:11 -0500 Subject: crypto: ccp - Fix XTS-AES-128 support on v5 CCPs commit e652399edba99a5497f0d80f240c9075d3b43493 upstream. Version 5 CCPs have some new requirements for XTS-AES: the type field must be specified, and the key requires 512 bits, with each part occupying 256 bits and padded with zeroes.
