From 3e2c0369fc46cd052a4f97cda57d879796bce790 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Fri, 16 Jun 2017 10:28:42 +0200 Subject: [PATCH 5/8] nbd: fix NBD over TLS (bz1461827) RH-Author: Paolo Bonzini Message-id: <20170616102842.16984-1-pbonzini@redhat.com> Patchwork-id: 75621 O-Subject: [RHEL7.4 qemu-kvm-rhev PATCH] nbd: fix NBD over TLS (bz1461827) Bugzilla: 1461827 RH-Acked-by: Daniel P. Berrange RH-Acked-by: Laszlo Ersek RH-Acked-by: Stefan Hajnoczi Upstream status: queued in my NBD tree, reviewed and tested (see below) When attaching the NBD QIOChannel to an AioContext, the TLS channel should be used, not the underlying socket channel. This is because, trivially, the TLS channel will be the one that we read/write to and thus the one that will get the qio_channel_yield() call.
