Description Thomas Neuber 2018-12-28 14:12:23 UTC
Description of problem:
cockpit and cockpit-pcp is installed and active on this system. The SELinux alerts appear during or after system (re)start.
SELinux is preventing find from 'getattr' accesses on the Verzeichnis /proc/sys/kernel/usermodehelper.

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

Wenn Sie denken, dass es find standardmäßig erlaubt sein sollte, getattr Zugriff auf usermodehelper directory 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 'find' --raw | audit2allow -M my-find
# semodule -X 300 -i my-find.pp
