Help with OVS code

I'm trying to implement security features to the OVS code as part of my project. I want to create a algorithm that would detect malicious controller on the network.

I want to do that by checking flow entries that OVS receives from the controllers. When OVS will receive flow entries from each controller I want to compare them and decide which flow entry to add to flow table and which one to drop.

I'm currently stuck with the OVS code. Could someone please point me to the function in the OVS code that receives the flow entries? Or a place where all received flow entries can be compared and later added or dropped.

Any version of OVS will do. The best for me is 2.0.0+, as this version we have on our PICA-8 switches.

If someone needs it take a look at this functions:

ofconn_run() -> handle_openflow() -> handle_flow_mod() -> add_flow()
