With my release manager hat on …
Do we consider support for VLAN tags on an AF packet interface a bug fix (to be
back ported) or a new feature (available from 17.10 onwards)?

Eddie,
I recently submitted a patch which updated the CentOS Vagrant support in
.../vpp/extras/Vagrantfile to CentOS 7.4
Please pull the latest VPP tree from master, install virtualbox, and run
vagrant/virtualbox as follows:
cd /extras/vagrant
export VPP_VAGRANT_DISTRO=centos7

Hi xyxue,
Ow, but if you’re running with vms, there’s no need to use net namespaces. If
your vms have e1000/vmxnet3 nics you can actually run vpp with dpdk. Just
configure the ip addresses in the two vpps and test with ping, from within one
of the vpps, that the topology is configured correctl
Hey,
I have created a patch to remove vlib_buffer_chain_validate() on July,
https://gerrit.fd.io/r/#/c/7382/ Remove unused call vlib_buffer_chain_validate()
But it is not merged yet.
For router plugin in vppsb, it works well on VPP 17.01, but it lacks
maintenance since then.

Nitin,
If you are referring to these counters in show error as transmission errors,
they are not really errors. Did you get a chance to try to send pings from the
other direction and capture the trace to see if the other VM is working fine? I

Dear Eddie,
As discussed in private email: I think that the version of CentOS on your build
system is too old. If memory serves, CentOS 7.3 is required. Google tells me
that the earliest Linux kernel with memfd support is 3.17; it looks like your
system is running a 3.10 derivative:

Ping fails because the remote VM did not respond the ARP requests. As far as I
can tell, The ARP request packets were correctly sent from VirtualEthernet0/0/0

Hi steven,
I did IPv4 ping. Some ICMPv6 router solicit messages were captured but those
were not part of IPv4 ping which I did.
I will send show vhost output soon.

Hi xyxue,
I think the issue may be the way you build your topology. You may actually want
to use 2 veth pairs, one per vpp instance. So something along the lines of:
Linux:
ip netns add vppns

ip link set dev vpp1 up
ip link set dev veth_vpp1 up net

Hi Pawel,
It looks like that function vlib_buffer_chain_validate was removed from
vlib/buffer.c prior to v17.01 and was never removed from the buffer_funcs.h

Damjan, can we just remove the call in the vppsb router code to
vlib_buffer_chain_validate(), or is something else needed?

Dear Nitin,
First off: exactly which LDXR / STXR instruction variant pairs is generated? I
begin to wonder if __sync_lock_test_and_set(...) might not be doing you any
favors. Given that dq->interrupt_pending is a u32, I would have expected a
4-byte instruction with (at worst) a 4-byte alignment
