[Qemu-devel] [PULL 12/38] chardev: tcp: postpone TLS work until machine


From: Eric Blake
Subject: [Qemu-devel] [PULL 12/38] chardev: tcp: postpone TLS work until machine done
Date: Fri, 16 Mar 2018 09:04:42 -0500

From: "Daniel P. Berrange" <address@hidden>

TLS handshake may create background GSource tasks, while we won't know
the correct GMainContext until the whole chardev (including frontend)
inited.  Let's postpone the initial TLS handshake until machine done.

For dynamically created tcp chardev, we don't postpone that by checking
the init_machine_done variable.
