Jenkins / Improvement JENKINS-33596
Disable DNSMultiCast & UDPBroadcastThread by default
Issue Type: Improvement Improvement
Assignee: Keith Zantow
Components: core
Created: 2016/Mar/16 4:41 PM
Labels: 2.0
Priority: Major Major
Reporter: Jesse Glick

In 2.0 we try to turn off listeners by default, but UDPBroadcastThread and DNSMultiCast are still started.

We should

  • create global settings (/configureSecurity) allowing these to be enabled or disabled
  • disable them by default
  • move the start and stop calls to within the associated classes using @Initializer/@Terminator

The third is to make it easier to split these off into a distinct plugin in the future. (Or fold them into the swarm plugin, which seems to be the major user of one of them, I cannot remember which.)

Re: Disable DNSMultiCast & UDPBroadcastThread by default

This was originally planned for the new setup wizard, but got dropped, so should be planned after 2.0.

Linking some apparently related issues which should be moved to the new component when the split is complete.

And how can we (got bitten by JENKINS-10160 yesterday) disable those for now?

It does not seem to be in progress. Keith Zantow, any updates?

Re: Disable DNSMultiCast & UDPBroadcastThread by default

I will be disabling this for Jenkins Evergreen and then closing this ticket since it's clearly stalled/dead.

Please either leave it open or file a separate issue with split-plugins-from-core.

Whatever then, this can be stalled somewhere else other than my backlog

Re: Disable DNSMultiCast & UDPBroadcastThread by default

Please just add a link here to whatever you wind up doing in Evergreen, so that if we revisit in Jenkins itself we remember what to clean up.

For example, this could be discarded once the baseline version of core supported by the POM has this stuff detached.

I'd love to see this done purely because the tests for it are flaky on my machine. Also, this feature should be disabled by default for security hardening.
