-Subject: [PATCH 1/2] apparmor: add base infastructure for socket mediation
-
-Provide a basic mediation of sockets. This is not a full net mediation
-but just whether a spcific family of socket can be used by an
-application, along with setting up some basic infrastructure for
-network mediation to follow.
-
-the user space rule hav the basic form of
- NETWORK RULE = [ QUALIFIERS ] 'network' [ DOMAIN ]
- [ TYPE | PROTOCOL ]
-
- DOMAIN = ( 'inet' | 'ax25' | 'ipx' | 'appletalk' | 'netrom' |
- 'bridge' | 'atmpvc' | 'x25' | 'inet6' | 'rose' |
- 'netbeui' | 'security' | 'key' | 'packet' | 'ash' |
- 'econet' | 'atmsvc' | 'sna' | 'irda' | 'pppox' |
- 'wanpipe' | 'bluetooth' | 'netlink' | 'unix' | 'rds' |

- 'phonet' | 'ieee802154' | 'caif' | 'alg' | 'nfc' |
- 'vsock' | 'mpls' | 'ib' | 'kcm' ) ','

- TYPE = ( 'stream' | 'dgram' | 'seqpacket' | 'rdm' | 'raw' |
- 'packet' )

- PROTOCOL = ( 'tcp' | 'udp' | 'icmp' )
