Description xzj8b3 2017-07-24 13:49:51 UTC
Description of problem:
SELinux is preventing cat from 'getattr' accesses on the file /run/tlp/last_pwr.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If si desidera sistemare l'etichetta. 
L'etichetta predefinita di /run/tlp/last_pwr dovrebbe essere tlp_var_run_t.
Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly.
Do
# /sbin/restorecon -v /run/tlp/last_pwr

*****  Plugin catchall (1.49 confidence) suggests   **************************

If si crede che cat dovrebbe avere possibilità di accesso getattr sui last_pwr file in modo predefinito.
Then si dovrebbe riportare il problema come bug.
E' possibile generare un modulo di politica locale per consentire questo accesso.
Do
allow this access for now by executing:
# ausearch -c 'cat' --raw | audit2allow -M my-cat
# semodule -X 300 -i my-cat.pp

Comment 5 Lukas Vrabec 2017-11-01 16:26:56 UTC
Did you tried what is in original report? /var/run/tlp/last_pwr has wrong context and restorecon should fix it: 

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If si desidera sistemare l'etichetta. 
L'etichetta predefinita di /run/tlp/last_pwr dovrebbe essere tlp_var_run_t.

Do
# /sbin/restorecon -v /run/tlp/last_pwr
