From 85c3b529f8ad4d65ba86b982ef050212ae7dd976 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Fri, 20 Nov 2009 11:00:12 -0500 Subject: SELinux: header generation may hit infinite loop If a permission name is long enough the selinux class definition generation tool will go into a infinite loop. This is because it's macro max() is fooled into thinking it is dealing with unsigned numbers. This patch makes sure the macro always uses signed number so 1 > -1.
