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.

37 * The following NetLabel payloads are supported by the CIPSO subsystem.
40 * Sent by an application to add a new DOI mapping table.
42 * Required attributes:
45 * NLBL_CIPSOV4_A_MTYPE
46 * NLBL_CIPSOV4_A_TAGLST
48 * If using CIPSO_V4_MAP_TRANS the following attributes are required:
50 * NLBL_CIPSOV4_A_MLSLVLLST
51 * NLBL_CIPSOV4_A_MLSCATLST
53 * If using CIPSO_V4_MAP_PASS or CIPSO_V4_MAP_LOCAL no additional attributes
57 * Sent by an application to remove a specific DOI mapping table from the
60 * Required attributes:
65 * Sent by an application to list the details of a DOI definition. On
66 * success the kernel should send a response using the following format.
68 * Required attributes:
72 * The valid response message format depends on the type of the DOI mapping,
73 * the defined formats are shown below.
75 * Required attributes:
77 * NLBL_CIPSOV4_A_MTYPE
78 * NLBL_CIPSOV4_A_TAGLST
80 * If using CIPSO_V4_MAP_TRANS the following attributes are required:
82 * NLBL_CIPSOV4_A_MLSLVLLST
83 * NLBL_CIPSOV4_A_MLSCATLST
85 * If using CIPSO_V4_MAP_PASS or CIPSO_V4_MAP_LOCAL no additional attributes
89 * This message is sent by an application to list the valid DOIs on the
90 * system. When sent by an application there is no payload and the
91 * NLM_F_DUMP flag should be set. The kernel should respond with a series of
92 * the following messages.
94 * Required attributes:
97 * NLBL_CIPSOV4_A_MTYPE
