Description of problem:
SELinux is preventing ebtables from 'read' accesses on the Datei ebtables.lock.

*****  Plugin catchall (100. confidence) suggests   **************************

Wenn Sie denken, dass es ebtables standardmäßig erlaubt sein sollte, read Zugriff auf ebtables.lock file zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# ausearch -c 'ebtables' --raw | audit2allow -M my-ebtables
# semodule -X 300 -i my-ebtables.pp

Comment 1 Zdenek Pytela 2021-05-03 11:08:40 UTC
Hi,

The file in the setroubleshoot report has incorrect label. The path was not logged, but in the likely case it is /run, you can fix the label with

  # /sbin/restorecon -v /run/ebtables.lock

This change, however, does not persist boot. Are you aware how the lockfile was created?

Comment 2 Frank Büttner 2021-05-03 14:40:44 UTC
I have simple start the firewalld service after removing the iptables/ip6ables service.
An then the message was shown.
