2 * NetLabel CIPSO/IPv4 Support
4 * This file defines the CIPSO/IPv4 functions for the NetLabel system. The
5 * NetLabel system manages static and dynamic label mappings for network
6 * protocols such as CIPSO and RIPSO.

36 * The following NetLabel payloads are supported by the CIPSO subsystem.
39 * Sent by an application to add a new DOI mapping table.
41 * Required attributes:
44 * NLBL_CIPSOV4_A_MTYPE
45 * NLBL_CIPSOV4_A_TAGLST
47 * If using CIPSO_V4_MAP_TRANS the following attributes are required:
49 * NLBL_CIPSOV4_A_MLSLVLLST
50 * NLBL_CIPSOV4_A_MLSCATLST
52 * If using CIPSO_V4_MAP_PASS or CIPSO_V4_MAP_LOCAL no additional attributes
56 * Sent by an application to remove a specific DOI mapping table from the
59 * Required attributes:
64 * Sent by an application to list the details of a DOI definition. On
65 * success the kernel should send a response using the following format.
67 * Required attributes:
71 * The valid response message format depends on the type of the DOI mapping,
72 * the defined formats are shown below.
74 * Required attributes:
76 * NLBL_CIPSOV4_A_MTYPE
77 * NLBL_CIPSOV4_A_TAGLST
79 * If using CIPSO_V4_MAP_TRANS the following attributes are required:
81 * NLBL_CIPSOV4_A_MLSLVLLST
82 * NLBL_CIPSOV4_A_MLSCATLST
84 * If using CIPSO_V4_MAP_PASS or CIPSO_V4_MAP_LOCAL no additional attributes
88 * This message is sent by an application to list the valid DOIs on the
89 * system. When sent by an application there is no payload and the
90 * NLM_F_DUMP flag should be set. The kernel should respond with a series of
91 * the following messages.
