Description of problem:

SELinux is preventing NetworkManager from open access on the file /etc/sysctl.conf.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that NetworkManager should be allowed open access on the sysctl.conf file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep NetworkManager /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

How reproducible:

When I open my PC and connect to only for Wi-fi It's come up everytime and I tried to allow for one time but still Warnings come-up

It was starting when I update last version of NetworkManager.Something must be have bug for NM or I also updated my SELinux recently too. Then I'm starting to see a lot times.

Steps to Reproduce:
1.After login
2.Autoconnect for Wifi
3.Selinux warning come up
4.Wifi connected but a little bit slow because of Selinux
5.Even google sometime cannot come-up (I also check with another PC and my Modem)

Actual results:

Selinux prevent to access sysctl.conf for NetworkManager

Expected results:

Selinux never come-up for this reason.
