From dfaebe9825ff34983778f287101bc5f3bce00640 Mon Sep 17 00:00:00 2001 From: Paul Moore Date: Fri, 10 Oct 2008 10:16:31 -0400 Subject: selinux: Fix missing calls to netlbl_skbuff_err() At some point I think I messed up and dropped the calls to netlbl_skbuff_err() which are necessary for CIPSO to send error notifications to remote systems. This patch re-introduces the error handling calls into the SELinux code.
