3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Vlad Yasevich <vyase...@redhat.com> [ Upstream commit a5b8db91442fce9c9713fcd656c3698f1adde1d6 ] Range/validity checks on rta_type in rtnetlink_rcv_msg() do not account for flags that may be set. This causes the function to return -EINVAL when flags are set on the type (for example NLA_F_NESTED).
