Trying to create an inet family nat chain would not cause nft_chain_nat.ko module auto-load due to missing module alias. The family is actually NFPROTO_INET which happens to be the same numerical value as AF_UNIX. Signed-off-by: Phil Sutter <phil@xxxxxx> --- This is obviously a hack to illustrate the problem and show a working solution. I'm not sure what a real fix would look like - maybe nf_tables should internally use NFPROTO_* defines instead of AF_* ones? Maybe it should translate NFPROTO_INET into AF_UNSPEC? --- net/netfilter/nft_chain_nat.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/net/netfilter/nft_chain_nat.c b/net/netfilter/nft_chain_nat.c index 2f89bde3c61cb..d3bf4a297c655 100644 --- a/net/netfilter/nft_chain_nat.c +++ b/net/netfilter/nft_chain_nat.c @@ -142,3 +142,6 @@ MODULE_ALIAS_NFT_CHAIN(AF_INET, "nat"); #ifdef CONFIG_NF_TABLES_IPV6 MODULE_ALIAS_NFT_CHAIN(AF_INET6, "nat"); #endif +#ifdef CONFIG_NF_TABLES_INET +MODULE_ALIAS_NFT_CHAIN(AF_UNIX, "nat"); +#endif -- 2.22.0
