I am writing a WFP driver to perform deep inspection at the Stream layer.
A context is associated at ALE_CONNECT (Connect layer) using FwpsFlowAssociateContext.
There is a specific need to associate a context in the Connect layer.
However for FlowEstablishedClassify or StreamClassify callouts, WFP passes the flowContext as 0.
Hence I am not able to dereference my context and perform the deep inspection at the stream layer.
Please let me know if there is anything I am missing here.
When the flow gets closed WFP calls AleConnectFlowDeleteFn() with the correct context which wad allocated during AleConnectClassify()
