From 1939ccdaa61ce6a1f57d83277b3d41d3a9ad3c58 Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Mon, 5 Mar 2018 14:43:24 +0800 Subject: [PATCH] qio: non-default context for TLS handshake MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A new parameter "context" is added to qio_channel_tls_handshake() is to allow the TLS to be run on a non-default context. Still, no functional change. Signed-off-by: Peter Xu Signed-off-by: Daniel P.
