Title: systemd-resolved: after network reconnection, DNSSEC unsigned zones treated as bogus, stop resolving Status in systemd: Unknown Status in systemd package in Ubuntu: New Bug description: On the MIT network (which runs some ancient version of BIND 9), systemd-resolved stops resolving anything that isn’t DNSSEC-signed after I disconnect and reconnect the network. Signed zones continue to resolve. This happens with either DNSSEC=yes or the default DNSSEC=allow- downgrade. $ systemd-resolve github.com github.com: 192.30.253.113 -- Information acquired via protocol DNS in 15.6ms. -- Data is authenticated: no $ # (disconnect and reconnect wifi) $ systemd-resolve github.com github.com: resolve call failed: DNSSEC validation failed: no-signature More debug information is available in my upstream report (https://github.com/systemd/systemd/issues/4175), which has gotten no response in the last week and a half. I’m refiling this here because I believe that this regression and others (bug 1588230, bug 1624071, bug 1624317, bug 1449001) indicate that systemd-resolved is not ready for production, and with final freeze just a week away, leaving systemd-resolved enabled for the yakkety release would be reckless.
