crypto: ccp - Fix AES XTS error for request sizes above 4096 2016-05-25T10:33:47+00:00 Tom Lendacky thomas.lendacky@amd.com 2016-05-20T22:33:03+00:00 ab6a11a7c8ef47f996974dd3c648c2c0b1a36ab1 The ccp-crypto module for AES XTS support has a bug that can allow requests greater than 4096 bytes in size to be passed to the CCP hardware. The CCP hardware does not support request sizes larger than 4096, resulting in incorrect output. The request should actually be handled by the fallback mechanism instantiated by the ccp-crypto module. Add a check to insure the request size is less than or equal to the maximum supported size and use the fallback mechanism if it is not.
