ip6_tunnel: fix potential NULL pointer dereference
[ Upstream commit c8965932a2e3b70197ec02c6741c29460279e2a8 ]
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 .
