|
* NetLabel - A management interface for maintaining network packet label |
|
* mapping tables for explicit packet labling protocols. |
|
* |
|
* Network protocols such as CIPSO and RIPSO require a label translation layer |
|
* to convert the label on the packet into something meaningful on the host |
|
* machine. In the current Linux implementation these mapping tables live |
|
* inside the kernel; NetLabel provides a mechanism for user space applications |
|
* to manage these mapping tables. |
|
* |
|
* NetLabel makes use of the Generic NETLINK mechanism as a transport layer to |
|
* send messages between kernel and user space. The general format of a |
|
* NetLabel message is shown below: |
|
* |
|
* +-----------------+-------------------+--------- --- -- - |
|
* | struct nlmsghdr | struct genlmsghdr | payload |
|
* +-----------------+-------------------+--------- --- -- - |
|
* |
|
* The 'nlmsghdr' and 'genlmsghdr' structs should be dealt with like normal. |
|
* The payload is dependent on the subsystem specified in the |
|
* 'nlmsghdr->nlmsg_type' and should be defined below, supporting functions |
|
* should be defined in the corresponding net/netlabel/netlabel_<subsys>.h|c |
|
* file. All of the fields in the NetLabel payload are NETLINK attributes, see |
|
* the include/net/netlink.h file for more information on NETLINK attributes. |
|
* |

|
* The catmap bitmap field MUST be a power of two in length and large |
|
* enough to hold at least 240 bits. Special care (i.e. check the code!) |
|
* should be used when changing these values as the LSM implementation |
|
