<pre>Hi there, how are you guys doing.
Not sure if I missed it in the codebase, but it appears that zone field is not
exported from ulogd right now. A git grep for 'zone' only turns up timezone.
According to the ovs ofctl, there is 'zone' information exported:
<a href="http://openvswitch.org/support/dist-docs/ovs-ofctl.8.txt">http://openvswitch.org/support/dist-docs/ovs-ofctl.8.txt</a>
My employer, Nutanix, would really like to use this so that we can distinguish
between vlans for the same 5-tuple (src IP, src port, dest IP, dest port,
protocol).
History of the zone concept:
- some discussion about using namespaces to solve 5-tuple collisions:
<a href="http://netdev.vger.kernel.narkive.com/tg0lEdAG/connection-tracking-and-vlan">http://netdev.vger.kernel.narkive.com/tg0lEdAG/connection-tracking-and-vlan</a>
- somewhere along the way, Patrick McHardy mentions the idea of "conntrack
zones"
- This the RFC (2010): <a href="https://lwn.net/Articles/370152/">https://lwn.net/Articles/370152/</a></pre>
