Description nino.corsi 2013-10-03 22:00:39 UTC
Description of problem:
SELinux is preventing /usr/bin/kmod from 'search' accesses on the directory /usr/lib/modules.

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

If si crede che kmod dovrebbe avere possibilità di accesso search sui modules directory in modo predefinito.
Then si dovrebbe riportare il problema come bug.
E' possibile generare un modulo di politica locale per consentire questo accesso.
Do
consentire questo accesso per il momento eseguendo:
# grep modprobe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Lukas Vrabec 2013-10-04 07:34:45 UTC
Hi, 

You should use: "# restorecon /usr/bin/kmod". Because your /usr/bin/kmod has type firewalld_t instead of insmod_exec_t.
