Hello, Do you know which setup is needed to trigger this denial? Is there any problem with the service logged in journal? If I remember correctly, it happened when connecting to a serial port of the Bluetooth device. What do you mean with 'Is there any problem with the service logged in journal? '? (In reply to fschaupp from comment #3) > What do you mean with 'Is there any problem with the service logged in > journal? > '? Trying to gather all relevant information. Apart from the AVC denial reported for "blueman-mechani" in audit log, did you also see any problem with the service as a user, or logged to journal? I got the denial report in Fedora and it didn't seem to work when using it in an application. So, well, I reported for the next user not to have the issue as always. FEDORA-2023-e74ea79879 has been submitted as an update to Fedora 37. https://bodhi.fedoraproject.org/updates/FEDORA-2023-e74ea79879 FEDORA-2023-e74ea79879 has been pushed to the Fedora 37 testing repository. Soon you'll be able to install the update with the following command: `sudo dnf upgrade --enablerepo=updates-testing --refresh --advisory=FEDORA-2023-e74ea79879` You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2023-e74ea79879 See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates. FEDORA-2023-e74ea79879 has been pushed to the Fedora 37 stable repository. If problem still persists, please make note of it in this bug report. |
Description of problem: Blueman: Connect to device offering a rfcomm serial device SELinux is preventing blueman-mechani from using the 'signal' accesses on a process. ***** Plugin catchall (100. confidence) suggests ************************** Wenn Sie denken, dass es blueman-mechani standardmäßig erlaubt sein sollte, signal Zugriff auf unconfined_t Prozesse zu erhalten.
