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.

37 * The following NetLabel payloads are supported by the management interface.
40 * Sent by an application to add a domain mapping to the NetLabel system.
42 * Required attributes:
45 * NLBL_MGMT_A_PROTOCOL
47 * If IPv4 is specified the following attributes are required:
49 * NLBL_MGMT_A_IPV4ADDR
50 * NLBL_MGMT_A_IPV4MASK
52 * If IPv6 is specified the following attributes are required:
54 * NLBL_MGMT_A_IPV6ADDR
55 * NLBL_MGMT_A_IPV6MASK
57 * If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
61 * If using NETLBL_NLTYPE_UNLABELED no other attributes are required.
64 * Sent by an application to remove a domain mapping from the NetLabel
67 * Required attributes:
72 * This message can be sent either from an application or by the kernel in
73 * response to an application generated LISTALL message. When sent by an
74 * application there is no payload and the NLM_F_DUMP flag should be set.
75 * The kernel should respond with a series of the following messages.
77 * Required attributes:
81 * If the IP address selectors are not used the following attribute is
84 * NLBL_MGMT_A_PROTOCOL
86 * If the IP address selectors are used then the following attritbute is
89 * NLBL_MGMT_A_SELECTORLIST
91 * If the mapping is using the NETLBL_NLTYPE_CIPSOV4 type then the following
92 * attributes are required:
96 * If the mapping is using the NETLBL_NLTYPE_UNLABELED type no other
97 * attributes are required.
100 * Sent by an application to set the default domain mapping for the NetLabel
103 * Required attributes:
105 * NLBL_MGMT_A_PROTOCOL
107 * If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
111 * If using NETLBL_NLTYPE_UNLABELED no other attributes are required.
114 * Sent by an application to remove the default domain mapping from the
115 * NetLabel system, there is no payload.
118 * This message can be sent either from an application or by the kernel in
119 * response to an application generated LISTDEF message. When sent by an
120 * application there is no payload. On success the kernel should send a
121 * response using the following format.
123 * If the IP address selectors are not used the following attribute is
126 * NLBL_MGMT_A_PROTOCOL
128 * If the IP address selectors are used then the following attritbute is
131 * NLBL_MGMT_A_SELECTORLIST
133 * If the mapping is using the NETLBL_NLTYPE_CIPSOV4 type then the following
134 * attributes are required:
138 * If the mapping is using the NETLBL_NLTYPE_UNLABELED type no other
139 * attributes are required.
142 * Sent by an application to request a list of configured NetLabel protocols
143 * in the kernel. When sent by an application there is no payload and the
144 * NLM_F_DUMP flag should be set. The kernel should respond with a series of
145 * the following messages.
147 * Required attributes:
149 * NLBL_MGMT_A_PROTOCOL
152 * Sent by an application to request the NetLabel version. When sent by an
153 * application there is no payload. This message type is also used by the
154 * kernel to respond to an VERSION request.
