Could you attach raw avc msgs? (/var/log/audit/audit.log) Thank you. I identified these messages (/var/log/audit/audit.log):

This bugzilla was triaged as "WONTFIX" by the SELinux team, due to third-party software component which can be fixed by component maintainer. To take advantage of Mandatory Access Control mechanism provided by SELinux, you (component maintainer) can ship custom SELinux policy as a subpackage of the affected component. As a starting point you can use policy provided by selinux-policy package. For more details about the custom product policy, please follow the https://fedoraproject.org/wiki/SELinux/IndependentPolicy guideline. Lukas, wait a second. The collectd policy is in selinux-policy-targeted, but you're now expecting me to work around these AVCs in the collectd package itself? I never confined collectd, and don't have the time, skills or the energy to maintain the SELinux policy for it. If I'm not mistaken you guys wrote the policy in the first place. So I'm sorry, but I'm giving you this issue back. If you can't keep up with the AVCs for collectd, please just remove the policy from selinux-policy-targeted. This bug appears to have been reported against 'rawhide' during the Fedora 27 development cycle. Changing version to '27'. selinux-policy-3.13.1-284.37.fc27 has been submitted as an update to Fedora 27. https://bodhi.fedoraproject.org/updates/FEDORA-2018-4bb4de2d86 selinux-policy-3.13.1-284.37.fc27 has been pushed to the Fedora 27 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2018-4bb4de2d86 selinux-policy-3.13.1-284.37.fc27 has been pushed to the Fedora 27 stable repository. If problems still persist, please make note of it in this bug report. |
