2013-07-15net: add support of mac-programming over macvtap in QEMU sideAmos Kong1-6/+127
Currently macvtap based macvlan device is working in promiscuous mode, we want to implement mac-programming over macvtap through Libvirt for better performance. Design: QEMU notifies Libvirt when rx-filter config is changed in guest, then Libvirt query the rx-filter information by a monitor command, and sync the change to macvtap device. Related rx-filter config of the nic contains main mac, rx-mode items and vlan table. This patch adds a QMP event to notify management of rx-filter change, and adds a monitor command for management to query rx-filter information. Test: If we repeatedly add/remove vlan, and change macaddr of vlan interfaces in guest by a loop script. Result: The events will flood the QMP client(management), management takes too much resource to process the events. Event_throttle API (set rate to 1 ms) can avoid the events to flood QMP client, but it could cause an unexpected delay (~1ms), guests guests normally expect rx-filter updates immediately. So we use a flag for each nic to avoid events flooding, the event is emitted once until the query command is executed. The flag implementation could not introduce unexpected delay. There maybe exist an uncontrollable delay if we let Libvirt do the real change, guests normally expect rx-filter updates immediately. But it's another separate issue, we can investigate it when the work in Libvirt side is done. Michael S. Tsirkin: tweaked to enable events on start Michael S.

2013-07-04e1000: cleanup process_tx_descAndrew Jones1-8/+10
Coverity complains about two overruns in process_tx_desc(). The complaints are false positives, but we might as well eliminate them. The problem is that "hdr" is defined as an unsigned int, but then used to offset an array of size 65536, and another of size 256 bytes. hdr will actually never be greater than 255 though, as it's assigned only once and to the value of tp->hdr_len, which is an uint8_t. This patch simply gets rid of hdr, replacing it with tp->hdr_len, which makes it consistent with all other tp member use in the function. v2: - also cleanup coding style issues in the touched lines Signed-off-by: Andrew Jones <drjones@redhat.com> Signed-off-by: Michael S.

2013-05-24rtl8139: flush queued packets when RxBufPtr is writtenStefan Hajnoczi1-0/+3
Net queues support efficient "receive disable". For example, tap's file descriptor will not be polled while its peer has receive disabled. This saves CPU cycles for needlessly copying and then dropping packets which the peer cannot receive. rtl8139 is missing the qemu_flush_queued_packets() call that wakes the queue up when receive becomes possible again. As a result, the Windows 7 guest driver reaches a state where the rtl8139 cannot receive packets. The driver has actually refilled the receive buffer but we never resume reception. The bug can be reproduced by running a large FTP 'get' inside a Windows 7 guest: $ qemu -netdev tap,id=tap0,... -device rtl8139,netdev=tap0 The Linux guest driver does not trigger the bug, probably due to a different buffer management strategy.

2013-05-07virtio-net: properly check the vhost status during status setJason Wang1-2/+2
Commit 32993698 (vhost: disable on tap link down) tries to disable the vhost also when the peer's link is down. But the check was not done properly, the vhost were only started when: 1) peer's link is not down 2) virtio-net has already been started. Since == have a higher precedence than &&, place a brace to make sure both the conditions were met then does the check. This fixes the crash when doing a savem after set the link off which let qemu crash and complains: virtio_net_save: Assertion `!n->vhost_started' failed. Cc: Michael S.

2013-05-06spapr_llan: fix device reenablingAlexey Kardashevskiy1-0/+2
Normally, the "tap" device is polled by QEMU if a guest NIC can receive packets. If a guest NIC is stopped during transfer (rmmod or ifdown), it may still have packets in a queue which have to be send to the guest before QEMU enables polling of a "tap" interface via tap_update_fd_handler(). However the spapr_llan device was missing the qemu_flush_queued_packets() call so the tap_send_completed() callback was never called and therefore "tap" interface polling was not enabled ever.

2013-04-30virtio-net: count VIRTIO_NET_F_MAC when calculating config_lenJason Wang1-0/+1
Commit 14f9b664 (hw/virtio-net.c: set config size using host features) tries to calculate config size based on the host features. But it forgets the VIRTIO_NET_F_MAC were always set for qemu later. This will lead a zero config len for virtio-net device when both VIRTIO_NET_F_STATUS and VIRTIO_NET_F_MQ were disabled form command line. Then qemu will crash when user tries to read the config of virtio-net. Fix this by counting VIRTIO_NET_F_MAC and make sure the config at least contains the mac address.
