Shuva,

I just verified that I can do a very similar MatchAny flow via RestConf and it gets written to the switch:

   $ curl -i -H "Content-Type: application/json" --data '{ "flow": [ {
   "id": "1000", "table_id": 0, "strict": false, "match": {},
   "instructions": { "instruction": [ { "order": 0, "go-to-table": {
   "table_id": 10 } } ] } } ] }' -X PUT --user admin:admin
   
http://127.0.0.1:8181/restconf/config/opendaylight-inventory:nodes/node/openflow:236095091025485/table/0/flow/1000


Here's the flow in the switch:

   $ sudo ovs-ofctl -O OpenFlow13 dump-flows br-int table=0
   OFPST_FLOW reply (OF1.3) (xid=0x2):
     cookie=0x0, duration=142.350s, table=0, n_packets=0, n_bytes=0,
   actions=goto_table:10


But, when I do this programmatically, I get the nasty exception:
(More exception details in original email)

   java.lang.NullPointerException: Match value must not be null
        at
   
com.google.common.base.Preconditions.checkNotNull(Preconditions.java:226)[65:com.google.guava:18.0.0]

        at
   
org.opendaylight.openflowplugin.impl.registry.flow.FlowRegistryKeyFactory.create(FlowRegistryKeyFactory.java:29)[286:org.opendaylight.openflowplugin.impl:0.3.0.SNAPSHOT]


So, there seems to be a bug in the OpenFlowPlugin code when creating flows programmatically. Now that I know that its still possible in Boron to create MatchAny flows like always, I'll look into finding where the bug is.

Notice, Im using OVS 2.5.90.

Brady

Shuva,

Thanks for the info.

Can you send me the curl/URL you used, please. I just tried this with SFC master from today, and still get the same problem.

Here is what is in the configuration data store, you can see that there is no match. Seems like now when the match is empty, it doesnt get written to config.

        "flow-node-inventory:table": [
          {
            "id": 2,
            "flow": [
              {
                "id": "2",
                "cookie_mask": 20,
                "table_id": 2,
                "priority": 5,
                "strict": false,
                "flags": "",
                "flow-name": "MatchAny",
                "idle-timeout": 0,
                "hard-timeout": 0,
                "cookie": 20,
                "barrier": false,
                "instructions": {
                  "instruction": [
                    {
                      "order": 0,
                      "go-to-table": {
                        "table_id": 3
                      }
                    }
                  ]
                }
              }
            ]
          },



Thanks,

Brady

    Hi Brady,

    I do see this error only while adding a flow without any
    match(<match>..</match>) . But with empty match
    fields(<match></match>) I donot see this error and I do see the
    flow getting provisioned on the switch.

    I am using Restconf for pushing the flows.

    Thanks

    Hello,

    Im getting an Exception when writing a MatchAny flow in Boron. The
    MatchAny flow has different names, but Im referring to an empty match.

    Here is the code Ive always used to create the Match:

            MatchBuilder matchBuilder = new MatchBuilder();
            return matchBuilder.build();

    The exception I get is below. Has the way of creating MatchAny
    flows changed recently??

    Thanks,

    Brady
