From 424a5da6919073392c11345d1b7baa9f31c62734 Mon Sep 17 00:00:00 2001 From: Cristian Stoica Date: Wed, 28 Jan 2015 11:03:05 +0200 Subject: crypto: testmgr - limit IV copy length in aead tests The working copy of IV is the same size as the transformation's IV. It is not necessary to copy more than that from the template since iv_len is usually less than MAX_IVLEN and the rest of the copied data is garbage.
