Hi Aaron (I didn't want to call someone fodder :-) ) Thank you for taking the time to report this bug and helping to make Ubuntu better. I'm interested in the regression you might have found.
The log looks like a forwarding loop on a ?cloudflare server?. I haven't seen the issue myself in all my virt work where dnsmasq is mostly around, I'm afraid you'll have to share a bit more details on your setup. - How did you install/setup/configure dnsmasq/systemd-resolved - Which host isn't existing the one you are resolving or one that you manage with dnsmasq? - What are the commands to trigger this? So far there isn't really enough information here for a developer to confirm this issue is a bug, or to begin working on it, so I am marking this bug Incomplete for now. If you can provide exact steps so that a developer can reproduce the original problem, then please add them to this bug and change the status back to New. ** Changed in: dnsmasq (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1688364 Title: Non existent host causes 100% cpu utilization by systemd-resolved and dnsmasq Status in dnsmasq package in Ubuntu: Incomplete Bug description: May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] googletagservices.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded googletagservices.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] googletagservices.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded googletagservices.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] googletagservices.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded googletagservices.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] googletagservices.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded googletagservices.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] googletagservices.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded googletagservices.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] googletagservices.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded googletagservices.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] googletagservices.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded googletagservices.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 May 04 13:32:07 cannon-fodder dnsmasq[8101]: forwarded cf.shareasimage.com to 127.0.0.53 May 04 13:32:07 cannon-fodder dnsmasq[8101]: query[A] cf.shareasimage.com from 127.0.0.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1688364/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
