net: cgroup: fix out of bounds accesses
dev->priomap is allocated by extend_netdev_table() called from update_netdev_tables(). And this is only called if write_priomap() is called. But if write_priomap() is not called, it seems we can have out of bounds accesses in cgrp_destroy(), read_priomap() & skb_update_prio() With help from Gao Feng Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Neil Horman <nhorman@tuxdriver.com> Cc: Gao feng <gaofeng@cn.fujitsu.com> Acked-by: Gao feng <gaofeng@cn.fujitsu.com> Signed-off-by: David S.
