Title:
Too long tunnel devices names
Status in OpenStack Neutron (virtual network service):
Fix Released
Bug description:
Openvswitch neutron agent create too long names for tunnel devices.
Ports name are created like %type-%remoteip.
For example for gre type tunnel, name is gre-192.168.201.10 which exceed max
length for linux network devices (15 chars).
This name pass throw openvswitch, but create failed port with ofport -1 and
proceed with error like this:
2014-02-17 11:25:14.048 22908 ERROR neutron.agent.linux.ovs_lib [-] Unable to
execute ['ovs-ofctl', 'add-flow', 'br-tun',
'hard_timeout=0,idle_timeout=0,priority=1,in_port=-1,actions=resubmit(,2)'].
Exception:
Command: ['sudo', '/usr/bin/neutron-rootwrap', '/etc/neutron/rootwrap.conf',
'ovs-ofctl', 'add-flow', 'br-tun',
'hard_timeout=0,idle_timeout=0,priority=1,in_port=-1,actions=resubmit(,2)']
Exit code: 1
Stdout: ''
Stderr: 'ovs-ofctl: -1: negative values not supported for in_port\n'
This bug affect only devices with long ip address 10.0.0.1 will pass,
but 192.168.201.10 fail.
Found in HAVANA with:
openvswitch: 1.9.3-1
linux: 3.2.54-2
But I think length limit will apply on all versions.
