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
