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,
62 * however the following attribute may optionally be sent:
67 * Sent by an application to remove a domain mapping from the NetLabel
70 * Required attributes:
75 * This message can be sent either from an application or by the kernel in
76 * response to an application generated LISTALL message. When sent by an
77 * application there is no payload and the NLM_F_DUMP flag should be set.
78 * The kernel should respond with a series of the following messages.
80 * Required attributes:
85 * If the IP address selectors are not used the following attribute is
88 * NLBL_MGMT_A_PROTOCOL
90 * If the IP address selectors are used then the following attritbute is
93 * NLBL_MGMT_A_SELECTORLIST
95 * If the mapping is using the NETLBL_NLTYPE_CIPSOV4 type then the following
96 * attributes are required:
100 * If the mapping is using the NETLBL_NLTYPE_UNLABELED type no other
101 * attributes are required.
104 * Sent by an application to set the default domain mapping for the NetLabel
107 * Required attributes:
109 * NLBL_MGMT_A_PROTOCOL
111 * If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
115 * If using NETLBL_NLTYPE_UNLABELED no other attributes are required,
116 * however the following attribute may optionally be sent:
121 * Sent by an application to remove the default domain mapping from the
122 * NetLabel system, there is no payload.
125 * This message can be sent either from an application or by the kernel in
126 * response to an application generated LISTDEF message. When sent by an
127 * application there may be an optional payload.
131 * On success the kernel should send a response using the following format:
133 * If the IP address selectors are not used the following attributes are
136 * NLBL_MGMT_A_PROTOCOL
139 * If the IP address selectors are used then the following attritbute is
142 * NLBL_MGMT_A_SELECTORLIST
144 * If the mapping is using the NETLBL_NLTYPE_CIPSOV4 type then the following
145 * attributes are required:
149 * If the mapping is using the NETLBL_NLTYPE_UNLABELED type no other
150 * attributes are required.
153 * Sent by an application to request a list of configured NetLabel protocols
154 * in the kernel. When sent by an application there is no payload and the
155 * NLM_F_DUMP flag should be set. The kernel should respond with a series of
156 * the following messages.
158 * Required attributes:
160 * NLBL_MGMT_A_PROTOCOL
163 * Sent by an application to request the NetLabel version. When sent by an
164 * application there is no payload. This message type is also used by the
165 * kernel to respond to an VERSION request.
