Known issues:
- Using openvswitch module in conjunction with upstream Linux tunnels:
* When using the openvswitch module distributed with OVS against kernel
versions 4.4 to 4.6, the openvswitch module cannot be loaded or used at
the same time as "ip_gre".
- Conntrack FTP ALGs: When using the openvswitch module distributed with
OVS, particular Linux distribution kernels versions may provide diminished
functionality. This typically affects active FTP data connections when
using "actions=ct(alg=ftp),..." in flow tables. Specifically:
* Centos 7.1 kernels (3.10.0-2xx) kernels are unable to correctly set
up expectations for FTP data connections in multiple zones,
eg "actions=ct(zone=1,alg=ftp),ct(zone=2,alg=ftp),...". Executing the
"ct" action for subsequent data connections may fail to determine that
the data connection is "related" to an existing connection.
* Centos 7.2 kernels (3.10.0-3xx) kernels may not establish FTP ALG state
correctly for NATed connections. As a result, flows that perform NAT,
eg "actions=ct(nat,ftp=alg,table=1),..." may fail to NAT the packet,
and will populate the "ct_state=inv" bit in the flow.
