ifa6_flags via routing socket/sysctl

[Tom Pusateri]

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
