Hi All, This is my bridge configuration:
Bridge br-int Controller "tcp:127.0.0.1:6653" is_connected: true fail_mode: secure Port br-int Interface br-int type: internal Port vxlan-vtp Interface vxlan-vtp type: vxlan options: {dst_port="4789", key=flow, local_ip="10.23.127.129", remote_ip=flow} Port br-ex-patch Interface br-ex-patch type: patch options: {peer=br-int-patch} I do something as the following steps: 1. Disconnect the controller 2. Change the vxlan port interface , the local_ip is set to be "flow”. The ovs-vswitchd is crashed, then I got the ovs-vswitchd core dump: #0 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 #1 0x00007f855f89542a in __GI_abort () at abort.c:89 #2 0x000055e14c6f7fae in ofputil_protocol_to_ofp_version (protocol=<optimized out>) at lib/ofp-protocol.c:123 #3 0x000055e14c6f32ce in ofputil_encode_port_status (ps=ps@entry=0x7ffdfceab670, protocol=<optimized out>) at lib/ofp-port.c:938 #4 0x000055e14c662dcb in connmgr_send_port_status (mgr=0x55e14da54370, source=source@entry=0x0, pp=pp@entry=0x55e14db9af50, reason=reason@entry=2 '\002') at ofproto/connmgr.c:1654 #5 0x000055e14c62bf26 in update_port (ofproto=ofproto@entry=0x55e14db778e0, name=name@entry=0x55e14dbe01a0 "vxlan-vtp") at ofproto/ofproto.c:2652 #6 0x000055e14c62c477 in ofproto_run (p=0x55e14db778e0) at ofproto/ofproto.c:1818 #7 0x000055e14c61a8bc in bridge_run__ () at vswitchd/bridge.c:2944 #8 0x000055e14c61bc71 in bridge_reconfigure (ovs_cfg=ovs_cfg@entry=0x55e14da5ab10) at vswitchd/bridge.c:721 #9 0x000055e14c61fba9 in bridge_run () at vswitchd/bridge.c:3023 #10 0x000055e14c2bdbdd in main (argc=<optimized out>, argv=<optimized out>) at vswitchd/ovs-vswitchd.c:125 From the code , the function connmgr_send_port_status try to send the message of the port status update to every controller connection, but since I disconnect the controller , the rconn state is S_BACKOFF. So based on the function ofconn_get_protocol, the protocol will be OFPUTIL_P_NONE. When calling ofputil_encode_port_status with none protocol, the ovs-vswitchd is crashed. connmgr_send_port_status. —> ofconn_get_protocol (conn disconnected, it return none protocol) —> ofputil_encode_port_status. (With None protocol , ovs-vswitchd crash) So I suggest to check if the protocol is null before calling ofputil_encode_port_status.
