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 IPv4 is specified the following attributes are required:
50 * NLBL_MGMT_A_IPV4ADDR
51 * NLBL_MGMT_A_IPV4MASK
53 * If IPv6 is specified the following attributes are required:
55 * NLBL_MGMT_A_IPV6ADDR
56 * NLBL_MGMT_A_IPV6MASK
58 * If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
60 * NLBL_MGMT_A_CV4DOI
62 * If using NETLBL_NLTYPE_UNLABELED no other attributes are required.
64 * o REMOVE:
65 * Sent by an application to remove a domain mapping from the NetLabel
66 * system.
68 * Required attributes:
70 * NLBL_MGMT_A_DOMAIN
72 * o LISTALL:
73 * This message can be sent either from an application or by the kernel in
74 * response to an application generated LISTALL message. When sent by an
75 * application there is no payload and the NLM_F_DUMP flag should be set.
76 * The kernel should respond with a series of the following messages.
78 * Required attributes:
80 * NLBL_MGMT_A_DOMAIN
82 * If the IP address selectors are not used the following attribute is
83 * required:
85 * NLBL_MGMT_A_PROTOCOL
87 * If the IP address selectors are used then the following attritbute is
88 * required:
90 * NLBL_MGMT_A_SELECTORLIST
92 * If the mapping is using the NETLBL_NLTYPE_CIPSOV4 type then the following
93 * attributes are required:
95 * NLBL_MGMT_A_CV4DOI
97 * If the mapping is using the NETLBL_NLTYPE_UNLABELED type no other
98 * attributes are required.
100 * o ADDDEF:
101 * Sent by an application to set the default domain mapping for the NetLabel
102 * system.
104 * Required attributes:
106 * NLBL_MGMT_A_PROTOCOL
108 * If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
110 * NLBL_MGMT_A_CV4DOI
112 * If using NETLBL_NLTYPE_UNLABELED no other attributes are required.
114 * o REMOVEDEF:
115 * Sent by an application to remove the default domain mapping from the
116 * NetLabel system, there is no payload.
118 * o LISTDEF:
119 * This message can be sent either from an application or by the kernel in
120 * response to an application generated LISTDEF message. When sent by an
121 * application there is no payload. On success the kernel should send a
122 * response using the following format.
124 * If the IP address selectors are not used the following attribute is
125 * required:
127 * NLBL_MGMT_A_PROTOCOL
129 * If the IP address selectors are used then the following attritbute is
130 * required:
132 * NLBL_MGMT_A_SELECTORLIST
134 * If the mapping is using the NETLBL_NLTYPE_CIPSOV4 type then the following
135 * attributes are required:
137 * NLBL_MGMT_A_CV4DOI
139 * If the mapping is using the NETLBL_NLTYPE_UNLABELED type no other
140 * attributes are required.
142 * o PROTOCOLS:
143 * Sent by an application to request a list of configured NetLabel protocols
144 * in the kernel. When sent by an application there is no payload and the
145 * NLM_F_DUMP flag should be set. The kernel should respond with a series of
146 * the following messages.
148 * Required attributes:
150 * NLBL_MGMT_A_PROTOCOL
152 * o VERSION:
153 * Sent by an application to request the NetLabel version. When sent by an
154 * application there is no payload. This message type is also used by the
155 * kernel to respond to an VERSION request.
157 * Required attributes:
159 * NLBL_MGMT_A_VERSION
