Date: Thu, 27 Oct 2022 00:25:58 +0100 From: Pavel Begunkov <asml.silence@...il.com> To: netdev@...r.kernel.org Cc: Jakub Kicinski <kuba@...nel.org>, "David S . Miller" <davem@...emloft.net>, io-uring@...r.kernel.org, John Fastabend <john.fastabend@...il.com>, asml.silence@...il.com Subject: [PATCH net 3/4] net/ulp: remove SOCK_SUPPORT_ZC from tls sockets Remove SOCK_SUPPORT_ZC when we're setting ulp as it might not support msghdr::ubuf_info, e.g. like TLS replacing ->sk_prot with a new set of handlers.
