Hi, As per our use case, we have created a vhost interface in VPP and further created lcp host interface for the same in linux using below commands:-
vpp# create vhost socket /tmp/vm00.sock vpp# lcp create VirtualEthernet0/0/0 host-if enp7s0 netns dataplane On linux, we then tried adding interface "enp7s0" in the bridge. # ip netns exec dataplane brctl addbr br1_vhost # ip netns exec dataplane brctl addif br1_vhost enp7s0 But as soon as we add this interface in the bridge, VPP crashes with below dump:- Jul 21 07:27:32 localhost vnet[15814]: received signal SIGSEGV, PC 0x7f494dff91f4, faulting address 0x0 Jul 21 07:27:32 localhost kernel: br1_vhost: port 1(enp7s0) entered blocking state Jul 21 07:27:32 localhost kernel: br1_vhost: port 1(enp7s0) entered disabled state Jul 21 07:27:32 localhost kernel: device enp7s0 entered promiscuous mode Jul 21 07:27:32 localhost vnet[15814]: #0 0x00007f49989d9c3b 0x7f49989d9c3b Jul 21 07:27:32 localhost vnet[15814]: #1 0x00007f4998321ce0 0x7f4998321ce0 Jul 21 07:27:32 localhost vnet[15814]: #2 0x00007f494dff91f4 nl_addr_get_family + 0x4 Jul 21 07:27:32 localhost vnet[15814]: #3 0x00007f494d9388d6 0x7f494d9388d6 Jul 21 07:27:32 localhost vnet[15814]: #4 0x00007f494d93ab53 0x7f494d93ab53 Jul 21 07:27:32 localhost vnet[15814]: #5 0x00007f494dfffbe2 0x7f494dfffbe2 Jul 21 07:27:32 localhost vnet[15814]: #6 0x00007f494ddaa6c8 0x7f494ddaa6c8 Jul 21 07:27:32 localhost vnet[15814]: #7 0x00007f494dffbd33 nl_cache_parse + 0x63 Jul 21 07:27:32 localhost vnet[15814]: #8 0x00007f494e00160f nl_msg_parse + 0x7f Jul 21 07:27:32 localhost vnet[15814]: #9 0x00007f494d93b2b4 0x7f494d93b2b4 Jul 21 07:27:32 localhost vnet[15814]: #10 0x00007f4998988d86 0x7f4998988d86 Jul 21 07:27:32 localhost vnet[15814]: #11 0x00007f4997ef5388 0x7f4997ef5388 Jul 21 07:27:32 localhost kernel: device enp7s0 left promiscuous mode Jul 21 07:27:32 localhost kernel: br1_vhost: port 1(enp7s0) entered disabled state What could be the possible reason for this crash? Is there anything we are missing from configuration point of view? Thanks and Regards, Chinmaya Agarwal.
