Pass reply direction traffic to CTĪnd promote connection to bidirectional when UDP connection stateĬhanges to 'assured'. With all the necessary infrastructure in place modify act_ct to offload Hardware offload state of such flows is updated by gc task by leveraging Add new flow_table flow flag that marks the flow for asynchronous update. Instead of assuming it and hardcoding hardware offload of every flow in

Add new flow_table flow flag that designates bidirectional connections Fix flow_table offload fixup algorithm to calculate flow timeoutĪccording to current connection state instead of hardcoded 'established' Provide ctinfo as a new structure field and modify act_ct to set it

'established replied' is assumed depending on the direction. CT meta action metadata doesn't store ctinfo as 'established' or Incrementally changing the following assumptions: To enabled offloading of unidirectional UDP NEW connections start with Such approach allows to hardcode a lot of assumptions intoĪct_ct, flow_table and flow_offload intermediate layer codes.
