From fbaf48387eb5e0e2bdc90d4c6f985a242a9fb0cc Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 3 Nov 2018 00:31:22 +0100 Subject: [PATCH] kernel: netfilter: chain filters merged into nf_tables.ko In mainline kernel commit 02c7b25e5f5 ("netfilter: nf_tables: build-in filter chain type") all chain filters were merged into one file and into one kernel module to save some memory. The code protected by these configuration options CONFIG_NF_TABLES_BRIDGE, CONFIG_NF_TABLES_IPV4, CONFIG_NF_TABLES_ARP, CONFIG_NF_TABLES_IPV6, CONFIG_NF_TABLES_NETDEV and CONFIG_NF_TABLES_INET was merged into the nft_chain_filter.c file which is now always compiled into the nf_tables.ko file. This only happened in kernel 4.19 and OpenWrt has to select these as modules in older kennel versions. Mark them as build-in in the kernel 4.19 specific kernel configuration file which will then not be overwritten by the package specific settings which try to make them modular again.
