4.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Florian Westphal <fw@xxxxxxxxx> [ Upstream commit e0758412208960be9de11e6d2350c81ffd88410f ] 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.
