reg matches with a mask causes a flood of "Message deserialization failed" exceptions

Bug Resolved Done Tomas Slusny Janki Chhatbar Fri, 3 Mar 2017 13:29:00 +0000 Mon, 27 Sep 2021 09:02:00 +0000 Thu, 16 Mar 2017 14:05:11 +0000 General 0 3 <p>Attachment flowstats1.pcap has been added with description: flow stats that cause the exception</p> <p>I looked into this exception a little bit, and I think it is caused by flow stats received from table=49. This table includes the rules like:<br/> cookie=0x8600000, duration=1.507s, table=49, n_packets=0, n_bytes=0, hard_timeout=10, priority=0,reg1=0x2/0xfffff,dl_src=fa:16:3e:7d:5a:42 actions=load:0x1-&gt;NXM_NX_REG4<span class="error">&#91;0..7&#93;</span></p> <p>I've tcpdumped the flowstats, and for some reason the REG1 OXM value is 8byte long, while openflowplugin assumes it is 4byte long - and I think this causes the decoder to fail (the exception is just a side effect of the decoder trying to decode the additional 4bytes as the next OXM field) .<br/> Other reg matches (for example, the ones from table=220) are indeed 4byte long.<br/> Not sure why the table=49 reg matches has a different size, the only reason I can think of is that those matches are created by OVS learn action. </p> <p>Attached a pcap of the problematic flow stats (look for the REG1 OXM match under table=49)</p> <p>Updated the bug title to be more informative, and moving bug to openflowplugin.</p> <p>It seems like the 4byte/8byte difference I noted earlier is because the REG1 match was masked. Therefore, the OXM data is 8byte long (4byte value + 4byte mask). It seems like this wasn't taken into account when decoding the OXM.</p> <p>Hi Tomas,</p> <p>Are you working on this? I was working on it. Not sure why I was unassigned from this bug. We can work together if you haven't still submitted the patch. If you have, please share its link.</p> <p>You was assigned to it, but it was not in progress, so I assumed that no one is working on it. Yes, I already made patch for it, and also Guarav made patch for it, so I don't know, I can abandon mine patch.</p> <p>Anyway, here is link to Guarav's patch: <a href="https://git.opendaylight.org/gerrit/#/c/51936/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/51936/</a> and here is link to mine: <a href="https://git.opendaylight.org/gerrit/#/c/51936/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/51936/</a>.</p> <ul> <li>link to my patch: <a href="https://git.opendaylight.org/gerrit/#/c/53259" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/53259</a></li> </ul> <p>(In reply to Tomas Slusny from comment #6)<br/> &gt; * link to my patch: <a href="https://git.opendaylight.org/gerrit/#/c/53259" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/53259</a></p> <p>looks to have worked.</p> <p>here is patch test job's karaf.log without these exceptions<br/> (Note: the karaf log seems to be amost 100k smaller now too)</p> <p><a href="https://logs.opendaylight.org/releng/jenkins092/netvirt-csit-1node-openstack-newton-nodl-v2-gate-stateful-carbon/408/archives/odl1_karaf.log.gz" class="external-link" target="_blank" rel="nofollow noopener">https://logs.opendaylight.org/releng/jenkins092/netvirt-csit-1node-openstack-newton-nodl-v2-gate-stateful-carbon/408/archives/odl1_karaf.log.gz</a></p> <p>just go back one job if you want to double check how it was<br/> <a href="https://logs.opendaylight.org/releng/jenkins092/netvirt-csit-1node-openstack-newton-nodl-v2-gate-stateful-carbon/407/archives/odl1_karaf.log.gz" class="external-link" target="_blank" rel="nofollow noopener">https://logs.opendaylight.org/releng/jenkins092/netvirt-csit-1node-openstack-newton-nodl-v2-gate-stateful-carbon/407/archives/odl1_karaf.log.gz</a></p> <p>Much appreciated Tomas!</p> <p>Works in local CSIT environment too. Thanks Tomas!</p> <p>Patch was merged, so based on comments I think I can close this.</p> Development External issue ID 7897 External issue URL Rank 0|i033rr: Status Whiteboard csit:exception
