From a18b989a5c12ca82ed37f94279273ddbc073758a Mon Sep 17 00:00:00 2001 From: Kim Phillips Date: Thu, 26 May 2011 13:30:34 +1000 Subject: [PATCH] crypto: caam - fix operator precedence in shared descriptor allocation setkey allocates 16 bytes (CAAM_CMD_SZ * DESC_AEAD_SHARED_TEXT_LEN) shy of what is needed to store the shared descriptor, resulting in memory corruption. Fix this.
