/*
* The following NetLabel payloads are supported by the management interface.
*
* o ADD:
* Sent by an application to add a domain mapping to the NetLabel system.
*
* Required attributes:
*
* NLBL_MGMT_A_DOMAIN
* NLBL_MGMT_A_PROTOCOL
*
* If IPv4 is specified the following attributes are required:
*
* NLBL_MGMT_A_IPV4ADDR
* NLBL_MGMT_A_IPV4MASK
*
* If IPv6 is specified the following attributes are required:
*
* NLBL_MGMT_A_IPV6ADDR
* NLBL_MGMT_A_IPV6MASK
*
* If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
*
* NLBL_MGMT_A_CV4DOI
*
* If using NETLBL_NLTYPE_UNLABELED no other attributes are required,
* however the following attribute may optionally be sent:
*
* NLBL_MGMT_A_FAMILY
*
* o REMOVE:
* Sent by an application to remove a domain mapping from the NetLabel
* system.
*
* Required attributes:
*
* NLBL_MGMT_A_DOMAIN
*
* o LISTALL:
* This message can be sent either from an application or by the kernel in
* response to an application generated LISTALL message. When sent by an
* application there is no payload and the NLM_F_DUMP flag should be set.
* The kernel should respond with a series of the following messages.
*
* Required attributes:
*
* NLBL_MGMT_A_DOMAIN
* NLBL_MGMT_A_FAMILY
*
* If the IP address selectors are not used the following attribute is
* required:
*
* NLBL_MGMT_A_PROTOCOL
*
* If the IP address selectors are used then the following attritbute is
* required:
*
* NLBL_MGMT_A_SELECTORLIST
*
* If the mapping is using the NETLBL_NLTYPE_CIPSOV4 type then the following
* attributes are required:
*
* NLBL_MGMT_A_CV4DOI
*
* If the mapping is using the NETLBL_NLTYPE_UNLABELED type no other
* attributes are required.
*
* o ADDDEF:
* Sent by an application to set the default domain mapping for the NetLabel
* system.
*
* Required attributes:
*
* NLBL_MGMT_A_PROTOCOL
*
* If using NETLBL_NLTYPE_CIPSOV4 the following attributes are required:
*
* NLBL_MGMT_A_CV4DOI
*
* If using NETLBL_NLTYPE_UNLABELED no other attributes are required,
* however the following attribute may optionally be sent:
*
* NLBL_MGMT_A_FAMILY
*
* o REMOVEDEF:
* Sent by an application to remove the default domain mapping from the
* NetLabel system, there is no payload.
*
* o LISTDEF:
* This message can be sent either from an application or by the kernel in
* response to an application generated LISTDEF message. When sent by an
* application there may be an optional payload.
*
* NLBL_MGMT_A_FAMILY
*
* On success the kernel should send a response using the following format:
*
* If the IP address selectors are not used the following attributes are
* required:
*
* NLBL_MGMT_A_PROTOCOL
* NLBL_MGMT_A_FAMILY
*
* If the IP address selectors are used then the following attritbute is
* required:
*
* NLBL_MGMT_A_SELECTORLIST
*
* If the mapping is using the NETLBL_NLTYPE_CIPSOV4 type then the following
* attributes are required:
*
* NLBL_MGMT_A_CV4DOI
*
* If the mapping is using the NETLBL_NLTYPE_UNLABELED type no other
* attributes are required.
*
* o PROTOCOLS:
* Sent by an application to request a list of configured NetLabel protocols
* in the kernel. When sent by an application there is no payload and the
* NLM_F_DUMP flag should be set. The kernel should respond with a series of
* the following messages.
*
* Required attributes:
*
* NLBL_MGMT_A_PROTOCOL
*
* o VERSION:
* Sent by an application to request the NetLabel version. When sent by an
* application there is no payload. This message type is also used by the
* kernel to respond to an VERSION request.
*
* Required attributes:
*
* NLBL_MGMT_A_VERSION
