2 * NetLabel Unlabeled Support
4 * This file defines functions for dealing with unlabeled packets for the
5 * NetLabel system. The NetLabel system manages static and dynamic label
6 * mappings for network protocols such as CIPSO and RIPSO.

37 * The following NetLabel payloads are supported by the Unlabeled subsystem.
40 * This message is sent from an application to specify if the kernel should
41 * allow unlabled packets to pass if they do not match any of the static
42 * mappings defined in the unlabeled module.
44 * Required attributes:
46 * NLBL_UNLABEL_A_ACPTFLG
49 * This message can be sent either from an application or by the kernel in
50 * response to an application generated LIST message. When sent by an
51 * application there is no payload. The kernel should respond to a LIST
52 * message with a LIST message on success.
54 * Required attributes:
56 * NLBL_UNLABEL_A_ACPTFLG
