GrapheneOS Organization Discusses Planned Improvements To Resolve Possible VPN Leakage (grapheneos.social)

One of our community members has been doing testing of Android VPN apps to check for leaks. They've found and reported 2 issues where leak blocking functionality doesn't appear to work as intended: one occurs with local network multicast and the other with DNS while VPN is down.

We're actively looking into these issues. Local network multicast not being blocked as expected is likely an OS bug caused by special handling of multicast. DNS issue may be another missed special case or a race condition, but it's possible the apps are handling it incorrectly.

One of the two issues (DNS) has spread to discussions about VPN apps elsewhere. Responsibility for blocking leaks is shared between the OS and VPN apps. It's a good thing that the OS provides standard infrastructure for this. Since the OS controls most of it, we can improve this.
