I have a network daemon that reads the interface list via the NET_RT_IFLIST/PF_ROUTE sysctl and then monitors changes to the interfaces using the routing socket.
I need to detect the interface address without the IN6_IFF_TEMPORARY flag set to advertise a permanent service.
The only way I have been able to figure out how to read the ifa6_flags is through a separate ioctl:
if (ioctl(s6, SIOCGIFAFLAG_IN6, &ifr6) < 0) {
perror("ifconfig: ioctl(SIOCGIFAFLAG_IN6)");
close(s6);
return;
}
Have I just missed the flags in the RTM_NEWADDR or RTM_IFINFO messages or are they not available via the routing socket messages?
Thanks,
Tom
