Start a virtual machine with its backend tap device attached to a brought up linux bridge. If we delete the linux bridge when vm is still running, we'll get the following error when trying to create a ovs bridge with the same name.
The reason is that ovs-router subsystem add the linux bridge into netdev_shash, but does not remove it when the bridge is deleted in the situation. When the bridge is deleted, ovs will receive a RTM_DELLINK msg, take this chance to remove the bridge in netdev_shash. ovs-vsctl: Error detected while setting up 'br-eth'. See ovs-vswitchd log for details. ovs-vswitchd log: 2017-05-11T03:45:25.293Z|00026|ofproto_dpif|INFO|system@ovs-system: Datapath supports recirculation 2017-05-11T03:45:25.293Z|00027|ofproto_dpif|INFO|system@ovs-system: MPLS label stack length probed as 1 2017-05-11T03:45:25.293Z|00028|ofproto_dpif|INFO|system@ovs-system: Datapath supports unique flow ids 2017-05-11T03:45:25.293Z|00029|ofproto_dpif|INFO|system@ovs-system: Datapath supports ct_state 2017-05-11T03:45:25.293Z|00030|ofproto_dpif|INFO|system@ovs-system: Datapath supports ct_zone 2017-05-11T03:45:25.293Z|00031|ofproto_dpif|INFO|system@ovs-system: Datapath supports ct_mark 2017-05-11T03:45:25.293Z|00032|ofproto_dpif|INFO|system@ovs-system: Datapath supports ct_label 2017-05-11T03:45:25.364Z|00001|ofproto_dpif_upcall(handler226)|INFO|received packet on unassociated datapath port 0 2017-05-11T03:45:25.368Z|00033|netdev_linux|WARN|ethtool command ETHTOOL_GFLAGS on network device br-eth failed: No such device 2017-05-11T03:45:25.368Z|00034|dpif|WARN|system@ovs-system: failed to add br-eth as port: No such device 2017-05-11T03:45:25.368Z|00035|bridge|INFO|bridge br-eth: using datapath ID 00002a51cf9f2841 2017-05-11T03:45:25.368Z|00036|connmgr|INFO|br-eth: added service controller "punix:/var/run/openvswitch/br-eth.mgmt" Change-Id: Ib5ead59bc91453f83549da89937c0d3607e0385e Signed-off-by: fukaige <fuka...@huawei.com> --- lib/netdev-linux.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/lib/netdev-linux.c b/lib/netdev-linux.c index 1e03c75..fae78e5 100644 --- a/lib/netdev-linux.c +++ b/lib/netdev-linux.c @@ -73,6 +73,7 @@ #include "timer.h" #include "unaligned.h" #include "openvswitch/vlog.h" +#include "tnl-ports.h" VLOG_DEFINE_THIS_MODULE(netdev_linux); @@ -749,6 +750,7 @@ netdev_linux_update(struct netdev_linux *dev, dev->get_ifindex_error = 0; } else { netdev_linux_changed(dev, change->ifi_flags, 0); + tnl_port_map_delete_ipdev(dev->up.name); } } else if (rtnetlink_type_is_rtnlgrp_addr(change->nlmsg_type)) { /* Invalidates in4, in6. */ -- 1.8.3.1 _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
