Dear List members




Hi,

I'm new to SElinux and I'm a bit careful with it, so up till now I want to run it in permissive mode. After reading a lot's of docs I fixed most of my problems, but there are still some errors in audit.log. Now I would like to ask you to review this errors and give me feedback if this rules are safe to add to my policy or not. In summary is my understanding correct that:

O auditctl, ifconfig, iptables-restor, dmesg and pppd try to write to the console,
O pppd searches something in the root home directory ??!,
O and iptables writes to a socket?

if I would add this policy to the module wouldn't it be too much (e.g. could for example pppd access all my files?)

Thanks for the answers,
Kind Regards, Tibor
