Title
neighbour: Fix null-ptr-deref in neigh_flush_dev().
Summary
In the Linux kernel, the following vulnerability has been resolved: neighbour: Fix null-ptr-deref in neigh_flush_dev(). kernel test robot reported null-ptr-deref in neigh_flush_dev(). [0] The cited commit introduced per-netdev neighbour list and converted neigh_flush_dev() to use it instead of the global hash table. One thing we missed is that neigh_table_clear() calls neigh_ifdown() with NULL dev. Let's restore the hash table iteration. Note that IPv6 module is no longer unloadable, so neigh_table_clear() is called only when IPv6 fails to initialise, which is unlikely to happen.
