Hi, Any idea how to send/retrieve router header information (according to RFC 3542) using sendmsg/recvmsg in 2.6 debian kernel ?
I used cmsg_level = IPPROTO_IPV6, cmsg_type = IPV6_RTHDR. did not work. Tried with IPPROTO_ROUTING (not mentioned in RFC 3542), sendmsg worked to retrieve iov_base and iov_len correctly. But after doing recvmsg, I am not able to get any cmsg_level = IPPROTO_IPV6 or IPPROTO_ROUTING with cmsg_type = IPV6_RTHDR. Please help IPV6_RECVRTHDR, IPV6_RECVPKTINFO, IPV6_RECVHOPOPTS, IPV6_RECVDSTOPTS options are not available in Linux (2.6.9 kernel), RFC3542 claims to set these options in order to receive routing header, pktinfo, destination option header respectively. IP6_TUNNEL_LIMIT is not found on linux. Is there any equivalent planned to support in future kernel versions? Please advise. Thanks in advance.
