ipv4, fib: pass LOOPBACK_IFINDEX instead of 0 to flowi4_iif
As suggested by Julian: Simply, flowi4_iif must not contain 0, it does not look logical to ignore all ip rules with specified iif. because in fib_rule_match() we do: if (rule->iifindex && (rule->iifindex != fl->flowi_iif)) goto out; flowi4_iif should be LOOPBACK_IFINDEX by default. We need to move LOOPBACK_IFINDEX to include/net/flow.h: 1) It is mostly used by flowi_iif 2) Fix the following compile error if we use it in flow.h by the patches latter: In file included from include/linux/netfilter.h:277:0, from include/net/netns/netfilter.h:5, from include/net/net_namespace.h:21, from include/linux/netdevice.h:43, from include/linux/icmpv6.h:12, from include/linux/ipv6.h:61, from include/net/ipv6.h:16, from include/linux/sunrpc/clnt.h:27, from include/linux/nfs_fs.h:30, from init/do_mounts.c:32: include/net/flow.h: In function ‘flowi4_init_output’: include/net/flow.h:84:32: error: ‘LOOPBACK_IFINDEX’ undeclared (first use in this function) Cc: Eric Biederman <ebiederm@xmission.com> Cc: Julian Anastasov <ja@ssi.bg> Cc: David S.
