Package: unbound Version: 1.4.22-3 Severity: important Dear Maintainer,
Unbound does not recover gracefully from network-level errors. For example, if it is running as a local resolver on a laptop it can easily be thrown into a broken state when connecting to a new network, or when trying to browse the web while accidentally disconnected from a network. 1. Disconnect laptop from a network 2. Restart unbound (to flush cache, simulates leaving it disconnected overnight) 3. Connect laptop to a network 4. Simulate a transient network failure by deleting the default route 5. `host www.google.com` - it does not work (obviously) 6. Fix the network failure by reinstating the default route or running "sudo dhclient eth0" 7. `host www.google.com` again. It is still broken. The problem can only be fixed by either manually flushing all the offending records or restarting unbound. This is not user friendly.
