[Qemu-devel] [RFC PATCH v4 00/15] port network layer onto glib

[Liu Ping Fan]

From: Liu Ping Fan <address@hidden>

summary:
  patch1: GSource event abstraction
  patch2~7: port network backend to glib
  patch8~11: make network core re-entrant
  patch12~15:  port the slirp backend onto glib

For the patch --slirp: make slirp event dispatch based on slirp instance, not 
global
The slirp_pollfds_fill/poll logic are untouch, but owning the format issue, it 
change much.
Will fix in next verion.


v3->v4:
  1.separate GSource event to dedicated file
  2.integrated with net core re-entrant
  3.make slirp/  re-entrant

v2->v3:
  1.drop hub and the frontend(virtio net)
  2.split the patch for NetClientSource

v1->v2:
  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 (15):
  util: introduce gsource event abstration
  net: introduce bind_ctx to NetClientInfo
  net: port tap onto GSource
  net: resolve race of tap backend and its peer
  net: port vde onto GSource
  net: port socket to 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
