Description Greg 2018-01-07 14:54:26 UTC 
Description of problem:
Fedora 27 installed on a 2013-ish Macbook Pro. Happens when waking from suspend (i.e. opening the lid).

Tried restorecon (/sbin/restorecon -v /run/tlp/lock_tlp), but it did not remove the issue. audit2allow fixes it.

Relevant output from ausearch is:
type=AVC msg=audit(1515323163.771:291): avc:  denied  { open } for  pid=11613 comm="tlp" path="/run/tlp/lock_tlp" dev="tmpfs" ino=17816 scontext=system_u:system_r:tlp_t:s0 tcontext=system_u:object_r:var_run_t:s0 tclass=file permissive=0
SELinux is preventing tlp from 'open' accesses on the file /run/tlp/lock_tlp.

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

If you want to fix the label. 
/run/tlp/lock_tlp default label should be 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/lock_tlp

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

If you believe that tlp should be allowed open access on the lock_tlp file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'tlp' --raw | audit2allow -M my-tlp
# semodule -X 300 -i my-tlp.pp

Comment 1 Lukas Vrabec 2018-01-08 12:40:17 UTC 
Please, update selinux-policy rpm package to the latest version and run:

If you want to fix the label. 
/run/tlp/lock_tlp default label should be 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.

# /sbin/restorecon -v /run/tlp/lock_tlp

Comment 2 Greg 2018-01-10 12:55:50 UTC 
If you read my comments, I already tried everything you suggested.

At the time of writing, my selinux-policy was already at the latest available via dnf (I tried dnf update selinux policy). This was selinux-policy-3.13.1-283.19.fc27.noarch.

I tried:
/sbin/restorecon -v /run/tlp/lock_tlp
and 
/sbin/restorecon -v /run/tlp/

This worked for some time, but the issue returned because the security context of the file got changed back to system_u:object_r:var_run_t:s0 (instead of system_u:object_r:tlp_var_run_t:s0). How can I figure out what is changing it and why?
