[PATCH 06/12] netfilter: kconfig: nat related expression depend on nftables core

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: 2018-09-11 05:17:35
Also in: netfilter-devel
Subsystem: networking [general], the rest · Maintainers: "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds 

From: Florian Westphal <fw@strlen.de>

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.

Fixes: 02c7b25e5f54 ("netfilter: nf_tables: build-in filter chain type")
