These PRs add an "app strict leak blocking" toggle which controls whether an app is able to use setsockopt(SO_BINDTODEVICE). The leak blocking is enabled by default for all non-system apps, meaning SO_BINDTODEVICE is disabled by default. A notification is displayed whenever an SO_BINDTODEVICE attempt is blocked, which provides easy navigation to the toggle. A warning is displayed when a user attempts to disable strict leak blocking.
The existing SO_BINDTODEVICE blocking implementation has been completely removed as it only applied to apps under lockdown VPN, not globally to all apps.
