Title:
dnsmasq focal 2.80 NODATA instead of NXDOMAIN bug
Status in dnsmasq package in Ubuntu:
Fix Released
Status in dnsmasq source package in Focal:
Fix Committed
Bug description:
[SRU]
[ Impact ]
Sometimes dnsmasq is incorrectly returning NODATA instead of NXDOMAIN.
This can lead to erroneous actions by clients who need to determine
whether a domain name exists or not.
[ Test Plan ]
In a focal VM, install dnsmasq (apt install dnsmasq) if it wasn't
installed yet.
#0 Disabling systemd-resolved service and enabling resolution through
dnsmasq.
# systemctl disable --now systemd-resolved.service
# rm -f /etc/resolv.conf
# cat > /etc/resolv.conf << __EOF__

__EOF__
# systemctl start dnsmasq.service
#1 Bad case

[ Where problems could occur ]
It changes the program's behaviour by classifying as NXDOMAIN what
used to be NODATA in some situations, so if a user had a workaround
for this (in the form of a script or other kind of automatization) it
will probably start to malfunction.
The last rebuilding of the package for Focal was in May, so if any new
dependencies or libs have been upgraded on this Ubuntu series this can
impact the new rebuild.
[ Other Info ]
The patch is applied upstream and originated from a bug filed on
Fedora side: https://bugzilla.redhat.com/show_bug.cgi?id=1674067
[Original Report]
---------------------------------------------------
We upgraded our openstack containers which host dnsmasq services from bionic
to focal. With this we got an update of dnsmasq from 2.79 to 2.80 which
introduced a bug in our setup where dnsmasq returns NODATA instead of NXDOMAIN.
This is already fixed upstream with the following commit [1].
The Ubuntu dnsmasq 2.80 package should get a backport with a release
for the focal packages which includes this bug fix.
