45 * NetLabel - A management interface for maintaining network packet label
46 * mapping tables for explicit packet labling protocols.
47 *
48 * Network protocols such as CIPSO and RIPSO require a label translation layer
49 * to convert the label on the packet into something meaningful on the host
50 * machine. In the current Linux implementation these mapping tables live
51 * inside the kernel; NetLabel provides a mechanism for user space applications
52 * to manage these mapping tables.
53 *
54 * NetLabel makes use of the Generic NETLINK mechanism as a transport layer to
55 * send messages between kernel and user space. The general format of a
56 * NetLabel message is shown below:
57 *
58 * +-----------------+-------------------+--------- --- -- -
59 * | struct nlmsghdr | struct genlmsghdr | payload
60 * +-----------------+-------------------+--------- --- -- -
61 *
62 * The 'nlmsghdr' and 'genlmsghdr' structs should be dealt with like normal.
63 * The payload is dependent on the subsystem specified in the
64 * 'nlmsghdr->nlmsg_type' and should be defined below, supporting functions
65 * should be defined in the corresponding net/netlabel/netlabel_<subsys>.h|c
Paul Moorefcd48282006-09-25 15:56:09 -070066 * file. All of the fields in the NetLabel payload are NETLINK attributes, see
67 * the include/net/netlink.h file for more information on NETLINK attributes.
