ipv4: fix endianness issue in inet_rtm_getroute_build_skb()
The UDP length field should be in network order. This removes the following sparse error: net/ipv4/route.c:3173:27: warning: incorrect type in assignment (different base types) net/ipv4/route.c:3173:27: expected restricted __be16 [usertype] len net/ipv4/route.c:3173:27: got unsigned long Fixes: 404eb77ea766 ("ipv4: support sport, dport and ip_proto in RTM_GETROUTE") Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Roopa Prabhu <roopa@nvidia.com> Cc: David Ahern <dsahern@kernel.org> Reviewed-by: David Ahern <dsahern@kernel.org> Signed-off-by: David S.
