From 2be4d74f2fd45460d70d4fe65cc1972ef45bf849 Mon Sep 17 00:00:00 2001 From: Chris PeBenito Date: Fri, 3 May 2013 09:05:39 -0400 Subject: Add SELinux policy capability for always checking packet and peer classes. Currently the packet class in SELinux is not checked if there are no SECMARK rules in the security or mangle netfilter tables. Some systems prefer that packets are always checked, for example, to protect the system should the netfilter rules fail to load or if the nefilter rules were maliciously flushed. Add the always_check_network policy capability which, when enabled, treats SECMARK as enabled, even if there are no netfilter SECMARK rules and treats peer labeling as enabled, even if there is no Netlabel or labeled IPSEC configuration. Includes definition of "redhat1" SELinux policy capability, which exists in the SELinux userpace library, to keep ordering correct. The SELinux userpace portion of this was merged last year, but this kernel change fell on the floor.
