This OVS crash was first sent to openvswitch bug report mailing list, but it was suggested it is posted to dpdk as crash is in netdev code.
What you did that make the problem appear.
- We have an openstack kilo setup. it has 3 controllers and 3 computes. 1 of the controllers runs an ODL, which manages the OVS on each compute host. The compute hosts are running an hlinux OS, which is HPE's Debian8-based OS.
each host has 2 numa nodes, each with 12 cores (24 Hyper Threaded). each numa with 64GB.
We patched neutron to create vhostuser ports (which is not available in stable kilo), in order to work with dpdk in order to achieve highest throughput possible.
OVS was running with "-c 4" and pmd-core-mask 0x38. all these cores were isolated.
nova was configured with vcpu_pin_set=6-11, and the flavor had 6 vCPUs. flavor had 16 1GB huge pages, backed up by real 1GB huge pages in host.
Then running a traffic generator inside 2 VMs, using DPDK, in order to generate traffic. sending directly to the other VMs mac and IP.
- What you expected to happen.
We expected traffic to flow.
- What actually happened.
OVS crashed (in dpdk code). Attached BT.
- The Open vSwitch version number (as output by ovs-vswitchd --version)
root@BASE-CCP-CPN-N0001-NETCLM:~# ovs-vswitchd --version
ovs-vswitchd (Open vSwitch) 2.5.0
Compiled Apr 4 2016 08:51:09
- Any local patches or changes you have applied (if any).
applied ce179f1163f947fe8dc5afa35a2cdd0756bb53a0
The following are also handy sometimes:
- The kernel version on which Open vSwitch is running (from /proc/version) and the distribution and version number of your OS (e.g. "Centos 5.0").
root@BASE-CCP-CPN-N0001-NETCLM:~# cat /proc/version
Linux version 3.14.48-1-amd64-hlinux (pbuilder@build) (gcc version 4.9.2 (Debian 4.9.2-10) ) #hlinux1 SMP Thu Aug 6 16:02:22 UTC 2015
- If you have Open vSwitch configured to connect to an OpenFlow controller, the output of ovs-ofctl show <bridge> for each <bridge> configured in the vswitchd configuration database.
We are using odl. attached outputs.
- A fix or workaround, if you have one
We disabled mrg_rxbuf (mrg_rxbuf=off) in qemu
We can supply more info if necessary, like our exact build process etc.

It looks like a known issue, which has been fixed in this release. So,
could you please just try again with the latest DPDK code? It should
be able to solve your issue.

Running with dpdk 16.04 and latest ovs from git, and removing "mrg_rxbuf=off" from virtio params, the crash is no longer observed. However, we are wittnessing ovs gets stuck, and will post to ovs mailing list:2016-05-02T17:26:18.804Z|00111|ovs_rcu|WARN|blocked 1000 ms waiting for pmd145 to quiesce

I'm starting to work on the vhost ABI refactoring, that I also have to
touch the vhost example code. The vhost example code, however, is very
messy, full of __very__ long lines. This would make a later diff to
apply the new vhost API be very ugly, therefore, not friendly for review.
This is how this cleanup comes.
Besides that, there is one enhancement patch, which handles the broadcast
packets so that we could rely the ARP request packet, to let vhost-switch
be more like a real switch. There is another patch that (hopefully) would
fix the mbuf allocation failure ultimately. I also added some guidelines
there as comments to show how to count how many mbuf entries is enough for
our usage.
In another word, an example is meant to be clean/simple and with good
coding style so that people can get the usage easily. So, one way or
another, this patch is good to have, even without this ABI refactoring
stuff.
Note that I'm going to apply it before the end of this week, if no objections.
v2: - some checkpatch fixes
- cleaned the code about device statistics
---

examples/vhost: remove the non-working zero copy code
