From e0758412208960be9de11e6d2350c81ffd88410f Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Sat, 25 Aug 2018 01:14:46 +0200 Subject: [PATCH] netfilter: kconfig: nat related expression depend on nftables core NF_TABLES_IPV4 is now boolean so it is possible to set NF_TABLES=m NF_TABLES_IPV4=y NFT_CHAIN_NAT_IPV4=y which causes: nft_chain_nat_ipv4.c:(.text+0x6d): undefined reference to `nft_do_chain' Wrap NFT_CHAIN_NAT_IPV4 and related nat expressions with NF_TABLES to restore the dependency.
