Message-Id: <20220412081459.263276-1-atenart@kernel.org> Date: Tue, 12 Apr 2022 10:14:59 +0200 From: Antoine Tenart <atenart@...nel.org> To: pablo@...filter.org, kadlec@...filter.org, fw@...len.de Cc: Antoine Tenart <atenart@...nel.org>, netfilter-devel@...r.kernel.org, netdev@...r.kernel.org Subject: [PATCH nf] netfilter: nf_tables: nft_parse_register can return a negative value Since commit 6e1acfa387b9 ("netfilter: nf_tables: validate registers coming from userspace.") nft_parse_register can return a negative value, but the function prototype is still returning an unsigned int.
