From 7ec8dc96e1cb45693f28f1287802ef6f2888dae0 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 12 Oct 2018 16:38:36 +0100 Subject: [PATCH] rxrpc: Fix incorrect conditional on IPV6 The udpv6_encap_enable() function is part of the ipv6 code, and if that is configured as a loadable module and rxrpc is built in then a build failure will occur because the conditional check is wrong: net/rxrpc/local_object.o: In function `rxrpc_lookup_local': local_object.c:(.text+0x2688): undefined reference to `udpv6_encap_enable' Use the correct config symbol (CONFIG_AF_RXRPC_IPV6) in the conditional check rather than CONFIG_IPV6 as that will do the right thing.
