[Qemu-devel] [PATCH v1 00/14] port network layer onto glib

[Liu Ping Fan <qemulist@gmail.com>]

summary:
  patch1: GSource event abstraction
  patch2~6: port network backend to glib
  patch7~10: make network core re-entrant
  patch11~14:  port the slirp backend onto glib

The slirp->lock's deadlock problem has been eliminated and works fine.
And other components seems more stable, so I change from RFCv- to v-




rfcv5->v1:
  1. re-arrange logic for net/socket.c

rfcv4->rfcv5:
  1.use GList to reimplement EventsGSource
  2.make readable()/writable() return events which the backend is interested in
  3.fix the slirp->lock's potential deadlock issue

rfcv3->rfcv4:
  1.separate GSource event to dedicated file
  2.integrated with net core re-entrant
  3.make slirp/  re-entrant

rfcv2->rfcv3:
  1.drop hub and the frontend(virtio net)
  2.split the patch for NetClientSource

rfcv1->rfcv2:
  1.NetClientState can associate with up to 2 GSource, for virtio net, one for tx, one for rx,
    so vq can run on different threads.
  2.make network front-end onto glib, currently virtio net dataplane



Liu Ping Fan (14):
  util: introduce gsource event abstraction
  net: introduce bind_ctx to NetClientInfo
  net: port vde onto GSource
  net: port socket to GSource
  net: port tap onto GSource
  net: port tap-win32 onto GSource
  net: hub use lock to protect ports list
  net: introduce lock to protect NetQueue
  net: introduce lock to protect NetClientState's peer's access
  net: make netclient re-entrant with refcnt
  slirp: make timeout local
  slirp: make slirp event dispatch based on slirp instance, not global
  slirp: handle race condition
  slirp: use lock to protect the slirp_instances
