Subject: [PATCH] drivers/crypto/nx: saves chaining value from co-processor
Date: Fri, 02 Aug 2013 18:13:58 -0500 [thread overview]
Message-ID: <1375485238.32477.41.camel@what-is-leg> (raw)
The chaining value from co-processor was not being saved. This value is
needed because it is used as the IV, for example by cts(cbc(aes)).
