Title:
systemd-resolved emits totally useless warning
Status in systemd package in Ubuntu:
New
Bug description:
With systemd-resolved taking care of resolving DNS requests, it will
emit following warning message when domain fails to resolve:
Jul 02 07:19:22 balancer1 systemd-resolved[1269]: Server returned
error NXDOMAIN, mitigating potential DNS violation DVE-2018-0001,
retrying transaction with reduced feature level UDP.
This warning message is missing information about the process that's
trying to resolve a domain and (this part is the more important bit)
information about the domain that systemd-resolved is trying to
resolve in the first place.
If the warning message cannot be made meaningful, it should be dropped
for good. I'd prefer to log at least the domain name that was being
tried to be resolved. Having pid and name of the process that needed
the information would be a plus.
