From: Ross Lagerwall <ross.lagerwall@xxxxxxxxxx> Date: Wed, 8 Feb 2017 10:57:37 +0000 > This fixes a crash when running out of grant refs when creating many > queues across many netdevs. > > * If creating queues fails (i.e. there are no grant refs available), > call xenbus_dev_fatal() to ensure that the xenbus device is set to the > closed state. > * If no queues are created, don't call xennet_disconnect_backend as > netdev->real_num_tx_queues will not have been set correctly. > * If setup_netfront() fails, ensure that all the queues created are > cleaned up, not just those that have been set up. > * If any queues were set up and an error occurs, call > xennet_destroy_queues() to clean up the napi context. > * If any fatal error occurs, unregister and destroy the netdev to avoid > leaving around a half setup network device. > > Signed-off-by: Ross Lagerwall <ross.lagerwall@xxxxxxxxxx> Applied. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx https://lists.xen.org/xen-devel
