ipv4: Fix "Set rt->rt_iif more sanely on output routes."
Commit 1018b5c01636c7c6bda31a719bda34fc631db29a ("Set rt->rt_iif more sanely on output routes.") breaks rt_is_{output,input}_route. This became the cause to return "IP_PKTINFO's ->ipi_ifindex == 0". To fix it, this does: 1) Add "int rt_route_iif;" to struct rtable 2) For input routes, always set rt_route_iif to same value as rt_iif 3) For output routes, always set rt_route_iif to zero. Set rt_iif as it is done currently. 4) Change rt_is_{output,input}_route() to test rt_route_iif Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: David S.
