Description of problem: Happens on multiple systems, seems to happen when switching users (from KDE (X) via SDDM (wayland) to KDE (X)). Version-Release number of selected component: selinux-policy-3.13.1-225.6.fc25.noarch Additional info: reporter: libreport-2.8.0 hashmarkername: setroubleshoot kernel: 4.9.3-200.fc25.x86_64 type: libreport I use KDE via SDDM Should I use this recommendation and allow sddm-greeter access to core_pattern as workaround? Янв 22 12:44:37 irina.homedesk.org.ua python3[1210]: SELinux is preventing sddm-greeter from read access on the file core_pattern. ***** Plugin catchall (100. confidence) suggests ******************* If you believe that sddm-greeter should be allowed read access on the core_pattern file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'sddm-greeter' --raw | audit2allow -M my-sddmgreeter # semodule -X 300 -i my-sddmgreeter.pp Description of problem: I updated packages on this date. Then I got the alert. That's all I know. Additional info: reporter: libreport-2.8.0 hashmarkername: setroubleshoot kernel: 4.9.4-201.fc25.x86_64 type: libreport I am getting this issue too, on Fedora 27 SELinux is preventing sddm-greeter from read access on the file core_pattern. Plugin: catchall SELinux denied access requested by sddm-greeter. It is not expected that this access is required by sddm-greeter and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. If you believe that sddm-greeter should be allowed read access on the core_pattern file by default. You should report this as a bug. You can generate a local policy module to allow this access. Allow this access for now by executing: # ausearch -c 'sddm-greeter' --raw | audit2allow -M my-sddmgreeter # semodule -X 300 -i my-sddmgreeter.pp This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora 'version' of '25'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 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 this bug is closed as described in the policy above. 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. Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 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. |
