From 28ef4002ec7b4be27f1110b83e255df8159c786a Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Tue, 20 Apr 2010 10:21:18 -0400 Subject: [PATCH] IMA: handle whitespace better IMA parser will fail if whitespace is used in any way other than a single space. Using a tab or even using 2 spaces in a row will result in a policy being rejected. This patch makes the kernel ignore whitespace a bit better.
