syncronize FilterDataProvider and PacketTunnelProvider for a flow

Is there way to synchronize these 2 providers for a connection like FilterDataProvider is called and once its done then packet of that connection should come to PacketTunnelProvider.

Not within the NetworkExtension framework.

Hi,

Is there a way to identify same connection between FilterDataProvider and PacketTunnelProvider. ?

I am trying to solve syncronization problem between two providers as I need to get pid first in FilterDataProvider, then take some decision on it, and based on that decision , it will decide where first packet of that flow needs to go in PacketTunnelProvider.

I saw "Identifier" in NEFilterFlow and "filterFlowIdentifier" (available only in 10.15.4+) in NEPacket metadata, are they same for same connection ?

When I tested I am getting valid "identifier" and nil in "filterFlowIdentifier", is nil getting is valid ?

Please let me know if there is any identifier or something else to correlate same connection between FilterDataProvider and PacketTunnelProvider. ?

Thanks

Kumar

I saw

Identifier

NEFilterFlow

and

filterFlowIdentifier

… in

NEPacket

metadata, are they same for same connection ?

I don’t know )-: My advice here is that you open a DTS tech support incident so that I, or perhaps Matt, can take an in-depth look into your issue.
