[ovs-discuss] learn action and controller action of openflow in ovs 2.3.2 version

[Lixing (F)]

Hi All

I am using ovs 2.3.2 version.
I want to use learn action and controller action of openflow like this:
ovs-ofctl add-flow br-test "table=0, priority=0 actions=learn(table=0,hard_timeout=10, priority=20),CONTROLLER:65535"

When I snoop the br-test, I do not receive the packet-in packet.

I analyzed the code, there is an bug in handle_upcalls function.
When excuting the function xlate_actions_for_side_effects that to send the packet to the OpenFlow controller,
the flow table has been modified by learn action.

This bug does not exist in the later version ovs2.4.0.
How do I fix this bug in version 2.3.2?

Thanks
