Eric Dumazet 4785305c05 ipv6: use siphash in rt6_exception_hash() ... A group of security researchers brought to our attention the weakness of hash function used in rt6_exception_hash() Lets use siphash instead of Jenkins Hash, to considerably reduce security risks. Following patch deals with IPv4.
