ip6_tunnel: fix potential NULL pointer dereference The function ip6_tnl_validate assumes that the rtnl attribute IFLA_IPTUN_PROTO always be filled . If this attribute is not filled by the userspace application kernel get crashed with NULL pointer dereference. This patch fixes the potential kernel crash when IFLA_IPTUN_PROTO is missing .
