[ovs-discuss] OVS dropping NSH packets that are correctly encapsulated
Hello, I'm trying to use OVS 2.11.9 (without controller) in Ubuntu 14.04 to push NSH and ETH headers to an ICMP packet. The topology is as follows: Client ---> (p1p1) Classifier (p1p2) ---> Server where p1p1 and p1p2 interfaces on the classifier are bound to the OVS bridge br0. The problem is that after a packet enters classifier's p1p1, it gets dropped by OVS datapath before it reaches br0. dmesg shows error message as [ 3538.861851] openvswitch: netlink: Flow actions may not be safe on all matching packets. ovs-vswitchd.log shows 2019-06-20T13:05:13.942Z|03925|dpif(handler7)|WARN|system@ovs-system: failed to put[create] (Invalid argument) ufid:7f5e3b96-75ba-4a36-8385-fcb4ee4cda93 recirc_id(0),dp_hash(0/0),skb_priority(0/0),in_port(2),skb_mark(0/0),eth(src=a0:36:9f:a3:5e:f0,dst=a0:36:9f:a3:5c:30),eth_type(0x0800),ipv4(src=10.0.0.1/0.0.0.0,dst=13.0.0.1,proto=1/0,tos=0/0,ttl=64/0,frag=no),icmp(type=8/0,code=0/0), actions:push_nsh(flags=2,ttl=63,mdtype=1,np=3,spi=0x1234,si=255,c1=0x11223344,c2=0x11223344,c3=0x11223344,c4=0x11223344),push_eth(src=a0:36:9f:a3:5c:30,dst=a0:36:9f:8e:4b:48),1 Any suggestion please? == dump-flows output == root@ovs-br-1:/home/chang# ovs-ofctl -O Openflow13 dump-flows br0 cookie=0x0, duration=669.284s, table=0, n_packets=669, n_bytes=65562, ip,in_port=p1p1,nw_dst=13.0.0.1 actions=encap(nsh(md_type=1)),set_field:2->nsh_flags,set_field:0x1234->nsh_spi,set_field:255->nsh_si,set_field:63->nsh_ttl,set_field:0x11223344->nsh_c1,set_field:0x11223344->nsh_c2,set_field:0x11223344->nsh_c3,set_field:0x11223344->nsh_c4,goto_table:4 cookie=0x0, duration=669.281s, table=0, n_packets=16, n_bytes=960, reset_counts priority=1000,arp,arp_tpa=10.0.0.10,arp_op=1 actions=move:NXM_OF_ETH_SRC[]->NXM_OF_ETH_DST[],set_field:a0:36:9f:a3:5c:30->eth_src,load:0x2->NXM_OF_ARP_OP[],move:NXM_NX_ARP_SHA[]->NXM_NX_ARP_THA[],load:0xa0369fa35c30->NXM_NX_ARP_SHA[],move:NXM_OF_ARP_SPA[]->NXM_OF_ARP_TPA[],load:0xa0a->NXM_OF_ARP_SPA[],IN_PORT cookie=0x0, duration=669.252s, table=4, n_packets=669, n_bytes=65562, packet_type=(1,0x894f) actions=encap(ethernet),set_field:a0:36:9f:a3:5c:30->eth_src,set_field:a0:36:9f:8e:4b:48->eth_dst,goto_table:10 cookie=0x0, duration=552.056s, table=10, n_packets=552, n_bytes=54096, dl_type=0x894f actions=output:p1p2 == appctl trace output == Flow: ip,in_port=1,vlan_tci=0x,dl_src=00:00:00:00:00:00,dl_dst=00:00:00:00:00:00,nw_src=0.0.0.0,nw_dst=13.0.0.1,nw_proto=0,nw_tos=0,nw_ecn=0,nw_ttl=0 bridge("br0") - 0. ip,in_port=1,nw_dst=13.0.0.1, priority 32768 encap(nsh(md_type=1)) set_field:2->nsh_flags set_field:0x1234->nsh_spi set_field:255->nsh_si set_field:63->nsh_ttl set_field:0x11223344->nsh_c1 set_field:0x11223344->nsh_c2 set_field:0x11223344->nsh_c3 set_field:0x11223344->nsh_c4 goto_table:4 4. packet_type=(1,0x894f), priority 32768 encap(ethernet) set_field:a0:36:9f:a3:5c:30->eth_src set_field:a0:36:9f:8e:4b:48->eth_dst goto_table:10 10. dl_type=0x894f, priority 32768 output:2 Final flow: in_port=1,vlan_tci=0x,dl_src=a0:36:9f:a3:5c:30,dl_dst=a0:36:9f:8e:4b:48,dl_type=0x894f,nsh_flags=2,nsh_ttl=63,nsh_mdtype=1,nsh_np=3,nsh_spi=0x1234,nsh_si=255,nsh_c1=0x11223344,nsh_c2=0x11223344,nsh_c3=0x11223344,nsh_c4=0x11223344,nw_proto=0,nw_tos=0,nw_ecn=0,nw_ttl=0 Megaflow: recirc_id=0,eth,ip,in_port=1,dl_src=00:00:00:00:00:00,dl_dst=00:00:00:00:00:00,nw_dst=13.0.0.1,nw_frag=no Datapath actions: push_nsh(flags=2,ttl=63,mdtype=1,np=3,spi=0x1234,si=255,c1=0x11223344,c2=0x11223344,c3=0x11223344,c4=0x11223344),push_eth(src=a0:36:9f:a3:5c:30,dst=a0:36:9f:8e:4b:48),1 == ovs-vsctl output == 9e1192fd-3f02-497f-90e5-64d24b24932f Bridge "br0" Port "p1p1" Interface "p1p1" Port "br0" Interface "br0" type: internal Port "p1p2" Interface "p1p2" ovs_version: "2.11.90" Regards, Chang ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss

The ovsdb-tool.log shows several bridges being inserted but only one of them has its datapath_type set to netdev. Is that intentional?
