From 2fe66ec242d3f76e3b0101f36419e7e5405bcff3 Mon Sep 17 00:00:00 2001 From: Eric Paris <eparis@redhat.com> Date: Tue, 23 Nov 2010 06:28:08 +0000 Subject: [PATCH] SELinux: indicate fatal error in compat netfilter code The SELinux ip postroute code indicates when policy rejected a packet and passes the error back up the stack. The compat code does not. This patch sends the same kind of error back up the stack in the compat code.
