From 4c5c30249452aaebf258751ea4222eba3dd3da4c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jan-Simon=20M=C3=B6ller?= Date: Mon, 2 Jul 2012 13:48:30 +0200 Subject: [PATCH] crypto: LLVMLinux: Remove VLAIS usage from crypto/testmgr.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaced the use of a Variable Length Array In Struct (VLAIS) with a C99 compliant equivalent. This patch allocates the appropriate amount of memory using a char array using the SHASH_DESC_ON_STACK macro. The new code can be compiled with both gcc and clang.
