/*
* 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
