Date: Mon, 17 Feb 2020 12:15:27 +0000 From: Jakub Sitnicki <jakub@...udflare.com> To: bpf@...r.kernel.org Cc: netdev@...r.kernel.org, kernel-team@...udflare.com, Daniel Borkmann <daniel@...earbox.net>, John Fastabend <john.fastabend@...il.com> Subject: [PATCH bpf-next 0/3] sockmap/ktls: Simplify how we restore sk_prot callbacks This series has been split out from "Extend SOCKMAP to store listening sockets" [0]. I think it stands on its own, and makes the latter series smaller, which will make the review easier, hopefully. The essence is that we don't need to do a complicated dance in sk_psock_restore_proto, if we agree that the contract with tcp_update_ulp is to restore callbacks even when the socket doesn't use ULP. This is what tcp_update_ulp currently does, and we just make use of it. Series is accompanied by a test for a particularly tricky case of restoring callbacks when we have both sockmap and tls callbacks configured in sk->sk_prot.
