      .Netavark no longer fails resolving DNS TCP queries

      Previously, when you ran a container in a Podman network, some domain names would not resolve even though they worked on the host system or in a container not using the Podman network. With this update, Netavark supports TCP DNS queries and the problem is fixed.

      Description

      *From: https://issues.redhat.com/browse/RHEL-17270*

      SME: pholzing@redhat.com 

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

      When running a container in a podman network I am not able to resolve some domain names, even though on the host system or even a container not using podman network it works OK.

      Please provide the package NVR for which bug is seen:

      aardvark-dns-2:1.8.0-1.el9

      How reproducible:

      always

      Steps to reproduce

      1. A complete reproducer will be added to a private comment in Jira card above.  From the issue https://github.com/containers/podman/issues/23239, the following will time out when tcp is not working, and will work when tcp is working.
      • podman run --rm --network=pasta alpine:latest sh -c "apk add --quiet --no-cache bind-tools && cat /etc/resolv.conf && time dig +tcp google.com"

      Expected results

      DNS resolving works in the container

      Actual results

      DNS resolving doesn't work in the container
