What were you trying to do that didn't work?

We are backporting new option into RHEL8 to address CVE-2020-14312. We have used different approach to fix the issue in RHEL9, but it has caused issues with other packages. They were kind of expecting /etc/dnsmasq.conf is file full of commented out options and often added just extra snippets into /etc/dnsmasq.d/*.conf files. But that did not work.

Please provide the package NVR for which bug is seen:

dnsmasq-2.85-14.el9.x86_64

How reproducible:

reliable

Steps to reproduce

1. Use local-service=host option in RHEL8 dnsmasq
2. Upgrade the system to RHEL9

Expected results

dnsmasq will accept the option without configuration modification, just like in RHEL8. It will not change behaviour after upgrade.

Actual results

dnsmasq does not recognize new option variant at the moment. If it is used, dnsmasq will fail to start.
