[ovs-discuss] bug: vxlan_sys_4789 complaining on ovs+dpdk?

[王志克]

Hi,

I am using ovs(2.8.1)+dpdk(17.05.2), and notice that there are lots of ovs log as below:

2017-10-23T21:55:13.382Z|00241|netdev_linux|INFO|ioctl(SIOCGIFINDEX) on vxlan_sys_4789 device failed: No such device
2017-10-23T21:55:13.384Z|00242|netdev_linux|INFO|ioctl(SIOCGIFINDEX) on vxlan_sys_4789 device failed: No such device
2017-10-23T21:55:13.387Z|00243|netdev_linux|INFO|ioctl(SIOCGIFINDEX) on vxlan_sys_4789 device failed: No such device
2017-10-23T21:55:13.390Z|00244|netdev_linux|INFO|ioctl(SIOCGIFINDEX) on vxlan_sys_4789 device failed: No such device

Simply debug shows below change, which finally calls netdev_vport_get_ifindex()->linux_get_ifindex(). In my opnion, it does NOT apply to OVS+DPDK mode.

        TUNNEL_CLASS("vxlan", "vxlan_sys", netdev_vxlan_build_header,
                                           netdev_tnl_push_udp_header,
                                           netdev_vxlan_pop_header,
                                           NETDEV_VPORT_GET_IFINDEX),  àon ovs2.7, it is NULL

Any idea for fix?

Br,
