From 81a59f000e1d4a60a03081a1fc64aee46d6f0c3e Mon Sep 17 00:00:00 2001 From: Tom Lendacky Date: Mon, 6 Jan 2014 13:34:17 -0600 Subject: crypto: ccp - Change data length declarations to u64 When performing a hash operation if the amount of data buffered and a request at or near the maximum data length is received then the length calcuation could wrap causing an error in executing the hash operation. Fix this by using a u64 type for the input and output data lengths in all CCP operations.
