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

38 * The following NetLabel payloads are supported by the management interface.
40 * o ADD:
41 * Sent by an application to add a domain mapping to the NetLabel system.
43 * Required attributes:
45 * NLBL_MGMT_A_DOMAIN
46 * NLBL_MGMT_A_PROTOCOL
48 * If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
50 * NLBL_MGMT_A_CV4DOI
52 * If using NETLBL_NLTYPE_UNLABELED no other attributes are required.
54 * o REMOVE:
55 * Sent by an application to remove a domain mapping from the NetLabel
56 * system.
58 * Required attributes:
60 * NLBL_MGMT_A_DOMAIN
62 * o LISTALL:
63 * This message can be sent either from an application or by the kernel in
64 * response to an application generated LISTALL message. When sent by an
65 * application there is no payload and the NLM_F_DUMP flag should be set.
66 * The kernel should respond with a series of the following messages.
68 * Required attributes:
70 * NLBL_MGMT_A_DOMAIN
71 * NLBL_MGMT_A_PROTOCOL
73 * If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
75 * NLBL_MGMT_A_CV4DOI
77 * If using NETLBL_NLTYPE_UNLABELED no other attributes are required.
79 * o ADDDEF:
80 * Sent by an application to set the default domain mapping for the NetLabel
81 * system.
83 * Required attributes:
85 * NLBL_MGMT_A_PROTOCOL
87 * If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
89 * NLBL_MGMT_A_CV4DOI
91 * If using NETLBL_NLTYPE_UNLABELED no other attributes are required.
93 * o REMOVEDEF:
94 * Sent by an application to remove the default domain mapping from the
95 * NetLabel system, there is no payload.
97 * o LISTDEF:
98 * This message can be sent either from an application or by the kernel in
99 * response to an application generated LISTDEF message. When sent by an
100 * application there is no payload. On success the kernel should send a
101 * response using the following format.
103 * Required attributes:
105 * NLBL_MGMT_A_PROTOCOL
107 * If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
109 * NLBL_MGMT_A_CV4DOI
111 * If using NETLBL_NLTYPE_UNLABELED no other attributes are required.
113 * o PROTOCOLS:
114 * Sent by an application to request a list of configured NetLabel protocols
115 * in the kernel. When sent by an application there is no payload and the
116 * NLM_F_DUMP flag should be set. The kernel should respond with a series of
117 * the following messages.
119 * Required attributes:
121 * NLBL_MGMT_A_PROTOCOL
123 * o VERSION:
124 * Sent by an application to request the NetLabel version. When sent by an
125 * application there is no payload. This message type is also used by the
126 * kernel to respond to an VERSION request.
128 * Required attributes:
130 * NLBL_MGMT_A_VERSION
