Description Aleksandar Kostadinov 2013-02-13 16:24:09 UTC
Fedora does support DNSSEC from version 17 [1]. It requires the ubound resolver for the purpose.

On the other hand NetworkManager does support dnsmasq as a local cache and resolver to allow for split DNS setup when using VPNs. dnsmasq does not support DNSSEC resolution. As I see it the DNSSEC and split DNS features are currently (in fedora 18) incompatible.

It seems best to me to make NetworkManager support ubound in the same way as dnsmasq. This will allow for easy and secure client side DNS configuration.

Another possible approach would be to implement DNSSEC in the OS resolver but I am assuming this has already been ruled out as an option. If anybody knows any background about this, that would be welcome.

Comment 1 Pavel Šimerda (pavlix) 2013-05-07 14:40:59 UTC
Yes. The DNSSEC support in Fedora is very... wobbly. Networkmanager definitely needs direct unbound support for features like split DNS.

Comment 2 Fedora End Of Life 2013-12-21 11:22:40 UTC
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '18'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 18's end of life.

Thank you for reporting this issue and we are sorry that we may not be 
able to fix it before Fedora 18 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior to Fedora 18's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Interesting, here they claim dnsmasq does support DNSSEC:
http://www.thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html

but man on fedora 20, still claims unsupported. Although now I see --proxy-dnssec is available, but that is not the same.

From my point of view the DNSSEC implementation is too big feature to
rebase dnsmasq in F20 to the latest version. However the version in rawhide
(2.71) is compiled with the DNSSEC support. Feel free to test it.

http://koji.fedoraproject.org/koji/buildinfo?buildID=517696

However I think we still want to use unbound as validating resolver rather
than dnsmasq, as unbound comes with nice dynamic reconfiguration tool.
Also the DNSSEC implementation got more testing.

Comment 5 Pavel Šimerda (pavlix) 2014-05-20 15:08:09 UTC
Hi Aleksandar,

there is a Fedora Change Page now for having a validating DNS resolver by default[1] and we plan to use Unbound for that for a couple of reasons, including the fact that Unbound can already run as a system service *and* be configured by NetworkManager. We have currently no reason to switch back to Dnsmasq and explore its configuration and DNSSEC capabilities. We already got a number of patches accepted upstream in Unbound and dnssec-trigger (which only works with unbound AFAIK).

I would like to update the information to also include various issues with the local DNSSEC resolver configuration but for now there's the mailing list announcement[2] and bugzilla[3].

Comment 6 Pavel Šimerda (pavlix) 2014-06-06 17:25:37 UTC
Upstream recently accepted a first prototype of the unbound plugin (see attached upstream bug report).

Comment 7 Jan Kurik 2015-07-15 14:51:39 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle.
Changing version to '23'.

(As we did not run this process for some time, it could affect also pre-Fedora 23 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.)

Comment 9 Fedora End Of Life 2016-12-20 12:35:01 UTC
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
