Description javiertury 2019-08-02 16:35:49 UTC
Description of problem:

In trace mode, tlp logger calls are blocked by selinux

Version-Release number of selected component (if applicable):

selinux-policy 3.14.3-42.fc30
tlp 1.2.1-1.fc30

How reproducible:

Follow https://linrunner.de/en/tlp/docs/tlp-configuration.html#tracemode

1. Add the following line to /etc/default/tlp
TLP_DEBUG="arg bat disk lock nm path pm ps rf run sysfs udev usb" 

2. Restart tlp service
$ systemctl restart tlp

3. Do something(e.g. suspend and resume laptop), then take a look at the logs
$ systemctl status tlp
$ tlp-stat -T

Actual results:

logger: Operation not permitted

Expected results:

Debug loggin events
