[Qemu-devel] [PATCH 0/8] Enable full IPv4/IPv6 dual stack support

From: Daniel P. Berrange
Subject: [Qemu-devel] [PATCH 0/8] Enable full IPv4/IPv6 dual stack support
Date: Thu, 10 Aug 2017 17:04:43 +0100

Currently all the network listeners in QEMU, except the VNC server,
are restricted to listening on a single socket. This makes it
impossible to fully support IPv4/IPv6 dual stack. We're restricted
to using IPV6_V6ONLY=0 to listen on both protocols from a single
socket, but this doesn't work at all on OpenBSD, and even where
supported it is quite crude (only really works for localhost and
wildcard addresses).

This patch series introduces a new object QIONetListener, which
encapsulates multiple QIOChannelSocket listeners. This makes it
trivial to support multiple listening sockets in any part of

Daniel P. Berrange (8):
  tests: add functional test validating ipv4/ipv6 address flag handling
  io: introduce a network socket listener API
  blockdev: convert internal NBD server to QIONetListener
  blockdev: convert qemu-nbd server to QIONetListener
  migration: convert socket server to QIONetListener
  chardev: convert the socket server to QIONetListener
  ui: convert VNC server to QIONetListener
  sockets: fix parsing of ipv4/ipv6 opts in parse_socket_addr
