Subject: [PATCH bpf-next 1/3] bpf, sk_msg: Let ULP restore sk_proto and write_space callback
Date: Mon, 17 Feb 2020 12:15:28 +0000 [thread overview]
Message-ID: <20200217121530.754315-2-jakub@cloudflare.com> (raw)
In-Reply-To: <20200217121530.754315-1-jakub@cloudflare.com>
We don't need a fallback for when the socket is not using ULP.
tcp_update_ulp handles this case exactly the same as we do in
sk_psock_restore_proto. Get rid of the duplicated code.
