From 6be3bcd75afb673a37a82e18ba46d50430f172c1 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Wed, 31 Jan 2018 18:13:39 +0100 Subject: netfilter: flowtable infrastructure depends on NETFILTER_INGRESS config NF_FLOW_TABLE depends on NETFILTER_INGRESS. If users forget to enable this toggle, flowtable registration fails with EOPNOTSUPP. Moreover, turn 'select NF_FLOW_TABLE' in every flowtable family flavour into dependency instead, otherwise this new dependency on NETFILTER_INGRESS causes a warning. This also allows us to remove the explicit dependency between family flowtables <-> NF_TABLES and NF_CONNTRACK, given they depend on the NF_FLOW_TABLE core that already expresses the general dependencies for this new infrastructure. Moreover, NF_FLOW_TABLE_INET depends on NF_FLOW_TABLE_IPV4 and NF_FLOWTABLE_IPV6, which already depends on NF_FLOW_TABLE. So we can get rid of direct dependency with NF_FLOW_TABLE. In general, let's avoid 'select', it just makes things more complicated.
