[OPNFLWPLUG-167] OF13 TunnelID Match Failures

Mon, 27 Sep 2021 09:01:12 +0000

Flowmods in the Neutron plugin have been failing recently. TunnelID matches are failing in OpenflowpluginTestCommandProvider. I narrowed this one down to the mask causing issues.

OSGI output from HEAD
---------------------
// OpenflowpluginTestCommandProvider
osgi> addMDFlow openflow:143948071978317 f77
2014-05-20 01:54:54.139 EDT [Gogo shell] INFO o.o.o.t.OpenflowpluginTestCommandProvider - TunnelID Match Called
2014-05-20 01:54:54.140 EDT [Gogo shell] INFO o.o.o.t.OpenflowpluginTestCommandProvider - TunnelID Match Called tunnel.getTunnelID ==> 10668
gogo: IllegalArgumentException: Invalid range: -1099511627519, expected: [[0‥18446744073709551615]].

When I comment out the mask the flowmod succeeds:
------------------------------------------------
private static MatchBuilder createTunnelIDMatch() {
MatchBuilder match = new MatchBuilder();
TunnelBuilder tunnel = new TunnelBuilder(); // tunnel id match
tunnel.setTunnelId(BigInteger.valueOf(10668));

// Commented out
// byte[] mask = new byte[]

{ (byte) -1, (byte) -1, (byte) -1, 0, 0, 0, (byte) 1, (byte) 1 }

;
// tunnel.setTunnelMask(new BigInteger(mask));

match.setTunnel(tunnel.build());
return match;
}

OSGI output with a successful flowmod after commenting out the mask:

OFPST_FLOW reply (OF1.3) (xid=0x2):

I can help debugging the root this week if it isn't obvious to you guys. I need to go through all of the flowmods as this was the first one I started with.

Thanks!
