Summary
To determine whether a packet endpoint is actually local, the Linux backend needs to expose all IP addresses assigned to the host, not just the selected capture interface address. A routing host can have multiple local addresses, such as
SlocalandSvpn, and process matching must know the full set. Using only one interface address can cause valid local traffic on another interface to be treated as forwarded, or forwarded traffic to be treated as localFixes #447
