[ovs-discuss] tracing flows with ct state

[Michael Kashin]

Hi,
I'm trying to use ofproto/trace to trace flows installed by OVN controller.
I start with a simple flow spec that I used in OVS before, I get to table
21 when packet gets submitted to connection tracker and that's where trace
stops:
Datapath actions: ct(zone=2),recirc(0x9f)

I've tried adding recirc_id along with the ct_state to the same flow but it
fails:

# ovs-appctl ofproto/trace br-int
in_port=13,ip,dl_src=fa:16:3e:4f:2f:b8,nw_src=10.0.0.2,nw_dst=8.8.8.8,dl_dst=fa:16:3e:0d:df:ea,recirc_id=0x9f,ct_state="new|trk"
Bridge: br-int
Flow:
recirc_id=0x9f,ct_state=new|trk,ip,in_port=13,vlan_tci=0x0000,dl_src=fa:16:3e:4f:2f:b8,dl_dst=fa:16:3e:0d:df:ea,nw_src=10.0.0.2,nw_dst=8.8.8.8,nw_proto=0,nw_tos=0,nw_ecn=0,nw_ttl=0

Final flow: unchanged
Megaflow: recirc_id=0x9f,ip,in_port=13,nw_frag=no
Datapath actions: drop
Translation failed (No recirculation context), packet is dropped.


Am I on the right track? Is this something achievable?

Cheers,
Michael
