Subject: [PATCH 4.19 17/30] netfilter: nft_nat: allow to specify layer 4 protocol NAT only
Date: Mon, 2 Aug 2021 15:44:55 +0200 [thread overview]
Message-ID: <20210802134334.622123918@linuxfoundation.org> (raw)
In-Reply-To: <20210802134334.081433902@linuxfoundation.org>
From: Pablo Neira Ayuso <pablo@netfilter.org>
[ Upstream commit a33f387ecd5aafae514095c2c4a8c24f7aea7e8b ]
nft_nat reports a bogus EAFNOSUPPORT if no layer 3 information is specified.
Fixes: d07db9884a5f ("netfilter: nf_tables: introduce nft_validate_register_load()")
