[GBP-285] NSH headers not recognized

Thu, 19 Oct 2017 21:25:08 +0000

There is a problem on Jenkins in groupbasedpolicy jobs. We can't upgrade OVS properly.

We moved from
curl https://raw.githubusercontent.com/pritesh/ovs/nsh-v8/third-party/start-ovs-deb.sh | bash
to
curl https://raw.githubusercontent.com/yyang13/ovs_nsh_patches/master/start-ovs-deb.sh | bash
since this patch got merged in Openflowplugin
https://git.opendaylight.org/gerrit/#/c/43697/

The installation script for new OVS should uninstall existing version of OVS and the install the new one.
This seems to finish successfully.

But when trying to add the following flows, an error is returned.

sudo ovs-ofctl add-flow $sw "priority=1000,nsi=255,actions=move:NXM_NX_NSH_MDTYPE[]~~>NXM_NX_NSH_MDTYPE[],move:NXM_NX_NSH_NP[]~~>NXM_NX_NSH_NP[],move:NXM_NX_NSP[]~~>NXM_NX_NSP[],load:254~~>NXM_NX_NSI[],move:NXM_NX_NSH_C1[]~~>NXM_NX_NSH_C1[],move:NXM_NX_NSH_C2[]~~>NXM_NX_NSH_C2[],move:NXM_NX_TUN_ID[0..31]~~>NXM_NX_TUN_ID[0..31],load:$TUNNEL~~>NXM_NX_TUN_IPV4_DST[],load:0x4->NXM_NX_TUN_GPE_NP[],IN_PORT" -OOpenFlow13

ovs-ofctl: NXM_NX_NSH_MDTYPE[]->NXM_NX_NSH_MDTYPE[]: unknown field `NXM_NX_NSH_MDTYPE

The problem seems to be that the new OVS does not recognize NSH headers. The problem seems to be localy significant to Jenkins, haven't been spot elsewhere.
I was wondering if someone from integration project can help us with this. Maybe it's just a matter of upgrading ovs in releng/builder and not while test is running.

I don't think that we can just replace github link or rewrite versions in releng builder, since installing this new ovs version require some extra work.

Thanks
