From 468ffddf19c1417947cac931c240b0d600e4b5bf Mon Sep 17 00:00:00 2001 From: Felix Beck Date: Mon, 7 Dec 2009 12:51:54 +0100 Subject: [S390] zcrypt: initialize ap_messages for cex3 exploitation AP messages need to be initialized, before they will be used. Values will be zeroized. This will be needed later when introducing support for the special commands.
