IPv6 advanced socket API options

You can control access for the IPv6 advanced socket API options that influence outbound packets.

For the IPV6_NEXTHOP, IPV6_TCLASS, IPV6_RTHDR, IPV6_HOPOPTS, IPV6_DSTOPTS, IPV6_RTHDRDSTOPTS, and IPV6_PKTINFO socket options, to set the socket option on setsockopt() or to use the corresponding ancillary data item on sendmsg(), an application must meet one of the following criteria:

Be APF authorized.
Have superuser authority.
The corresponding SERVAUTH resource name in Table 1 is defined, and the application has at least READ access to the resource.

Table 1. Socket option resource names
Socket option/Ancillary data item	Resource name
IPV6_NEXTHOP	EZB.SOCKOPT.sysname.tcpname.IPV6_NEXTHOP
IPV6_TCLASS	EZB.SOCKOPT.sysname.tcpname.IPV6_TCLASS
IPV6_RTHDR	EZB.SOCKOPT.sysname.tcpname.IPV6_RTHDR
IPV6_HOPOPTS	EZB.SOCKOPT.sysname.tcpname.IPV6_HOPOPTS
IPV6_DSTOPTS	EZB.SOCKOPT.sysname.tcpname.IPV6_DSTOPTS
IPV6_RTHDRDSTOPTS	EZB.SOCKOPT.sysname.tcpname.IPV6_RTHDRDSTOPTS
IPV6_PKTINFO	EZB.SOCKOPT.sysname.tcpname.IPV6_PKTINFO
IPV6_HOPLIMIT	EZB.SOCKOPT.sysname.tcpname.IPV6_HOPLIMIT

For the IPV6_HOPLIMIT socket option, to set a hop limit greater than the default using either the IPV6_UNICAST_HOPS or IPV6_MULTICAST_HOPS socket option on setsockopt() or the IPV6_HOPLIMIT ancillary data item on sendmsg(), an application must meet one of the following criteria:

Be APF authorized.
Have superuser authority.
EZB.SOCKOPT.sysname.tcpname.IPV6_HOPLIMIT is defined, and the application has at least READ access to this resource.
