46 * NetLabel - A management interface for maintaining network packet label
47 * mapping tables for explicit packet labling protocols.
48 *
49 * Network protocols such as CIPSO and RIPSO require a label translation layer
50 * to convert the label on the packet into something meaningful on the host
51 * machine. In the current Linux implementation these mapping tables live
52 * inside the kernel; NetLabel provides a mechanism for user space applications
53 * to manage these mapping tables.
54 *
55 * NetLabel makes use of the Generic NETLINK mechanism as a transport layer to
56 * send messages between kernel and user space. The general format of a
57 * NetLabel message is shown below:
58 *
59 * +-----------------+-------------------+--------- --- -- -
60 * | struct nlmsghdr | struct genlmsghdr | payload
61 * +-----------------+-------------------+--------- --- -- -
62 *
63 * The 'nlmsghdr' and 'genlmsghdr' structs should be dealt with like normal.
64 * The payload is dependent on the subsystem specified in the
65 * 'nlmsghdr->nlmsg_type' and should be defined below, supporting functions
66 * should be defined in the corresponding net/netlabel/netlabel_<subsys>.h|c
Paul Moorefcd48282006-09-25 15:56:09 -070067 * file. All of the fields in the NetLabel payload are NETLINK attributes, see
68 * the include/net/netlink.h file for more information on NETLINK attributes.
