Arch Linux

Description:
systemd-networkd and systemd-resolved (am not sure which one is exactly the culprit) fail at DNS resolution in version 247.4-1.

Additional info:
$ resolvectl status
Global
Protocols: +LLMNR +mDNS -DNSOverTLS DNSSEC=allow-downgrade/unsupported
resolv.conf mode: uplink
Current DNS Server: 1.1.1.1
DNS Servers: 1.1.1.1 9.9.9.11 8.8.8.8 2606:4700:4700::1111 2620:fe::10 2001:4860:4860::8888

Steps to reproduce:

- Install systemd-247.4-1 and use systemd-networkd and systemd-resolved for network and DNS
- resolving DNS fails

Additional details: DNS is reachable, pinging 1.1.1.1 is successful. Resolution of multicast DNS also fails.

$ resolvectl query google.de
google.de: resolve call failed: 'google.de' does not have any RR of the requested type

$ resolvectl query laserbox.local
laserbox.local: resolve call failed: All attempts to contact name servers or networks failed

Just to add, pinging the IP of laserbox.local is successful.

Downgrading to 247.3-1 and restarting systemd-networkd and resolved fixes this:

$ resolvectl query laserbox.local
laserbox.local: 192.168.178.11 -- link: br0

-- Information acquired via protocol mDNS/IPv4 in 135.9ms.
-- Data is authenticated: no

$ resolvectl query google.de
google.de: 2a00:1450:400e:80d::2003 -- link: br0
172.217.168.227 -- link: br0

-- Information acquired via protocol DNS in 28.9ms.
