Hi I have seen Mr.Ping Pan's implementation of this. This seems to be just for receiving a packet with some IP option through a raw IP socket. This doesn't seem to be containing the kernel processing part of a packet with router alert option. In netinet6 I have seen that the ip6_input() function sets ours = 1; when it gets a packet with router alert option. Is something similar done in case of IPv4 too? If that's the case, I couldn't figure it out in this patch. Or is it already there in the standard kernel itself? Could some one tell me how a packet with router alert option is handled in ip_input(), or give me some pointers to some description of this processing? thanks & regards Madhavi.
