From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Subject: [PATCH] netfilter: conntrack: add weak IPV6 dependency Date: Fri, 6 Jul 2018 14:59:52 +0200 Message-ID: <20180706130005.3640993-1-arnd@arndb.de> Cc: Arnd Bergmann , =?UTF-8?q?M=C3=A1t=C3=A9=20Eckl?= , Fernando Fernandez Mancera , "Pablo M. Bermudo Garay" , Felix Fietkau , netfilter-devel@vger.kernel.org, coreteam@netfilter.org, netdev@vger.kernel.org, linux-kernel@vger.kernel.org To: Pablo Neira Ayuso , Jozsef Kadlecsik , Florian Westphal , "David S. Miller" Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org Now that the conntrack module contains code for ipv6, we can no longer have it built-in while IPv6 itself is a loadable module: net/netfilter/nf_conntrack_proto.o: In function `nf_ct_netns_do_get': nf_conntrack_proto.c:(.text+0x88c): undefined reference to `nf_defrag_ipv6_enable' net/netfilter/nf_conntrack_proto.o:(.rodata+0x178): undefined reference to `nf_conntrack_l4proto_icmpv6' This adds a dependency on IPv6 that makes it possible to still build the conntrack module with IPv6 disabled, but avoids the broken configuration.
