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 | |
fcd48280 PM |
66 | * 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. | |
