Subject: [PATCH bpf-next 01/10] bpf: Use ipv6_only_sock in bpf_tcp_gen_syncookie
Date: Tue, 19 Oct 2021 17:46:46 +0300 [thread overview]
Message-ID: <20211019144655.3483197-2-maximmi@nvidia.com> (raw)
In-Reply-To: <20211019144655.3483197-1-maximmi@nvidia.com>
Instead of querying the sk_ipv6only field directly, use the dedicated
ipv6_only_sock helper.
