From fc038410b4b1643766f8033f4940bcdb1dace633 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 9 May 2007 16:42:20 -0700 Subject: [UDP]: Fix AF-specific references in AF-agnostic code. __udp_lib_port_inuse() cannot make direct references to inet_sk(sk)->rcv_saddr as that is ipv4 specific state and this code is used by ipv6 too. Use an operations vector to solve this, and this also paves the way for ipv6 support for non-wild saddr hashing in UDP. Signed-off-by: David S.
