Hi, all I got the following compile errors when I compile IPv6 as a module and most of the rest are built into core kernel. David Miller insists we should fix this kind of error and not by adding Kconfig tricks. net/built-in.o: In function `nf_tproxy_get_sock_v6': /home/wangcong/linux/include/net/netfilter/nf_tproxy_core.h:177: undefined reference to `udp6_lib_lookup' /home/wangcong/linux/include/net/netfilter/nf_tproxy_core.h:177: undefined reference to `udp6_lib_lookup' net/built-in.o: In function `tproxy_tg_init': /home/wangcong/linux/net/netfilter/xt_TPROXY.c:415: undefined reference to `nf_defrag_ipv6_enable' net/built-in.o: In function `socket_mt_init': /home/wangcong/linux/net/netfilter/xt_socket.c:366: undefined reference to `nf_defrag_ipv6_enable' My .config is: CONFIG_NET_IPGRE=m CONFIG_IPV6=m CONFIG_INET6_AH=m CONFIG_INET6_ESP=m CONFIG_INET6_IPCOMP=m CONFIG_IPV6_MIP6=m CONFIG_INET6_XFRM_TUNNEL=m CONFIG_INET6_TUNNEL=m CONFIG_INET6_XFRM_MODE_TRANSPORT=m CONFIG_INET6_XFRM_MODE_TUNNEL=m CONFIG_INET6_XFRM_MODE_BEET=m CONFIG_INET6_XFRM_MODE_ROUTEOPTIMIZATION=m CONFIG_IPV6_SIT=m CONFIG_IPV6_TUNNEL=m CONFIG_IPV6_GRE=m CONFIG_NF_CONNTRACK_H323=m CONFIG_NETFILTER_XT_TARGET_TEE=m CONFIG_NETFILTER_XT_TARGET_TCPMSS=m CONFIG_NETFILTER_XT_MATCH_HASHLIMIT=m CONFIG_NETFILTER_XT_MATCH_PHYSDEV=m CONFIG_NF_NAT_H323=m CONFIG_NF_DEFRAG_IPV6=m CONFIG_NF_CONNTRACK_IPV6=m CONFIG_IP6_NF_IPTABLES=m CONFIG_IP6_NF_MATCH_AH=m CONFIG_IP6_NF_MATCH_EUI64=m CONFIG_IP6_NF_MATCH_FRAG=m CONFIG_IP6_NF_MATCH_OPTS=m CONFIG_IP6_NF_MATCH_HL=m CONFIG_IP6_NF_MATCH_IPV6HEADER=m CONFIG_IP6_NF_MATCH_MH=m CONFIG_IP6_NF_MATCH_RT=m CONFIG_IP6_NF_TARGET_HL=m CONFIG_IP6_NF_FILTER=m CONFIG_IP6_NF_TARGET_REJECT=m CONFIG_IP6_NF_MANGLE=m CONFIG_IP6_NF_RAW=m CONFIG_IP6_NF_SECURITY=m CONFIG_NF_NAT_IPV6=m CONFIG_IP6_NF_TARGET_MASQUERADE=m CONFIG_BRIDGE_NF_EBTABLES=m CONFIG_BRIDGE_EBT_BROUTE=m CONFIG_BRIDGE_EBT_T_FILTER=m CONFIG_BRIDGE_EBT_T_NAT=m CONFIG_BRIDGE_EBT_802_3=m CONFIG_BRIDGE_EBT_AMONG=m CONFIG_BRIDGE_EBT_ARP=m CONFIG_BRIDGE_EBT_IP=m CONFIG_BRIDGE_EBT_IP6=m CONFIG_BRIDGE_EBT_LIMIT=m CONFIG_BRIDGE_EBT_MARK=m CONFIG_BRIDGE_EBT_PKTTYPE=m CONFIG_BRIDGE_EBT_STP=m CONFIG_BRIDGE_EBT_VLAN=m CONFIG_BRIDGE_EBT_ARPREPLY=m CONFIG_BRIDGE_EBT_DNAT=m CONFIG_BRIDGE_EBT_MARK_T=m CONFIG_BRIDGE_EBT_REDIRECT=m CONFIG_BRIDGE_EBT_SNAT=m CONFIG_BRIDGE_EBT_LOG=m CONFIG_BRIDGE_EBT_ULOG=m CONFIG_BRIDGE_EBT_NFLOG=m CONFIG_IP_SCTP=m CONFIG_BRIDGE=m CONFIG_BONDING=m all the rest are either =y or =n.
