+Smack Netlabel Exceptions
+
+You will often find that your labeled application has to talk to the outside,
+unlabeled world. To do this there's a special file /smack/netlabel where you can
+add some exceptions in the form of :
+@IP1       LABEL1 or
+@IP2/MASK  LABEL2
+
+It means that your application will have unlabeled access to @IP1 if it has
+write access on LABEL1, and access to the subnet @IP2/MASK if it has write
+access on LABEL2.
+
+Entries in the /smack/netlabel file are matched by longest mask first, like in
+classless IPv4 routing.
+
+A special label '@' and an option '-CIPSO' can be used there :
+@      means Internet, any application with any label has access to it
+-CIPSO means standard CIPSO networking
+
+If you don't know what CIPSO is and don't plan to use it, you can just do :
+echo 127.0.0.1 -CIPSO > /smack/netlabel
+echo 0.0.0.0/0 @      > /smack/netlabel
+
+If you use CIPSO on your 192.168.0.0/16 local network and need also unlabeled
+Internet access, you can have :
+echo 127.0.0.1      -CIPSO > /smack/netlabel
+echo 192.168.0.0/16 -CIPSO > /smack/netlabel
+echo 0.0.0.0/0      @      > /smack/netlabel

-When:   2.6.30 at the earliest
-Why:    In 2.6.18 the Secmark concept was introduced to replace the "compat_net"
