The problem is in patch 3/4 as I added #include <linux/netfilter/nf_conntrack_sctp.h> in include/net/netns/conntrack.h, but I saw similar things also with DCCP. <...> CC kernel/sysctl_binary.o In file included from ./include/linux/netfilter.h:14:0, from ./include/uapi/linux/netfilter/nf_conntrack_tuple_common.h:5, from ./include/uapi/linux/netfilter/nf_conntrack_sctp.h:5, from ./include/linux/netfilter/nf_conntrack_sctp.h:5, from ./include/net/netns/conntrack.h:13, from ./include/net/net_namespace.h:25, from ./include/linux/init_task.h:15, from init/init_task.c:1: ./include/linux/netdevice.h:1859:2: error: unknown type name ‘possible_net_t’ possible_net_t nd_net; ^ (possile_net_t is in net_namespace.h). > Is there a kernel side conflict between uapi and net/netns headers? Looks like a circular dependency is here, or nf_conntrack_tuple_common.h is including the wrong netfilter.h. From within net/netns/conntrack.h I can include only those UAPI files that don't include <linux/netfilter.h> (for example, nf_conntrack_tcp.h that uses '2' instead of IP_CT_DIR_MAX). Do you have any suggestion? thank you in advance, -- davide -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
