From d4ffb02dee2fcb20e0c8086a8d1305bf885820bb Mon Sep 17 00:00:00 2001 From: Willem de Bruijn Date: Mon, 18 Nov 2019 10:40:51 -0500 Subject: net/tls: enable sk_msg redirect to tls socket egress Bring back tls_sw_sendpage_locked. sk_msg redirection into a socket with TLS_TX takes the following path: tcp_bpf_sendmsg_redir tcp_bpf_push_locked tcp_bpf_push kernel_sendpage_locked sock->ops->sendpage_locked Also update the flags test in tls_sw_sendpage_locked to allow flag MSG_NO_SHARED_FRAGS. bpf_tcp_sendmsg sets this.
