Miller 1177917960 -0700 [PATCH] INET : IPV4 UDP lookups converted to a 2 pass algo Some people want to have many UDP sockets, binded to a single port but many different addresses. We currently hash all those sockets into a single chain. Processing of incoming packets is very expensive, because the whole chain must be examined to find the best match. I chose in this patch to hash UDP sockets with a hash function that take into account both their port number and address : This has a drawback because we need two lookups : one with a given address, one with a wildcard (null) address.
