Perform postprocessing of a VPN tunnel instance.
After some VPN tunnel activity has taken place, the VPN tunnel's state may need updating and some follow-up action may be required. This function controls the necessary postprocessing. It is called by many other functions that handle VPN tunnel related activity, such as multi_process_incoming_link(), multi_process_outgoing_link(), multi_process_incoming_tun(), multi_process_outgoing_tun(), and multi_process_timeout(), among others.
- Parameters
-
m - The single multi_contextstructure.mi - The multi_instanceof the VPN tunnel to be postprocessed.flags - Fast I/O optimization flags.
- Returns
- True, if the VPN tunnel instance mi was not closed due to a signal during processing.
- False, if the VPN tunnel instance mi was closed.
