WFP callout altitudes
Does WFP support driver altitudes for the callouts like minifilters do?
My issue is a VPN driver is interfering with the rebindings my driver is doing so I want to make sure I can always be in position to make the final rebinding call.
If an altitude like loading is not possible, is there a way to finish the callback after calling FwpsApplyModifiedLayerData along the same lines of a minifilter returning FLT_PREOP_COMPLETE? I know there is the flag 'FWPS_CLASSIFY_FLAG_REAUTHORIZE_IF_MODIFIED_BY_OTHERS' but if both drivers use that flag then I would think you are basically back to square one.
Howdy, Stranger!
