From fee9dee730a40f671c1972a324ed54f0d68523e1 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Thu, 25 Oct 2007 18:54:46 -0700 Subject: [UDP]: Make use of inet_iif() when doing socket lookups. UDP currently uses skb->dev->ifindex which may provide the wrong information when the socket bound to a specific interface. This patch makes inet_iif() accessible to UDP and makes UDP use it. The scenario we are trying to fix is when a client is running on the same system and the server and both client and server bind to a non-loopback device.
