Create loadable module:
[root@xxxxxxxxxx ~]# cat /tmp/1.log | grep type=AVC | audit2allow -M smartd_my
******************** IMPORTANT ***********************
To make this policy package active, execute:
semodule -i smartd_my.pp
Load module:
[root@xxxxxxxxxx ~]# semodule -i smartd_my.pp
[root@xxxxxxxxxx ~]# echo $?
0
Check that module exists in modules list:
[root@xxxxxxxxxx ~]# semodule -l | grep smartd
smartd_my 1.0
Check that current mode is enforcing:
[root@xxxxxxxxxx ~]# sestatus
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: enforcing
Mode from config file: enforcing
Policy version: 24
Policy from config file: targeted
Restart smartd (service smartd restart) and check audit.log again:
