Description sheepdestroyer 2015-03-01 06:03:17 UTC
Description of problem:
SELinux is preventing nm-l2tp-service from 'unlink' accesses on the file nm-xl2tpd.conf.4356.

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

If you believe that nm-l2tp-service should be allowed unlink access on the nm-xl2tpd.conf.4356 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:
# grep nm-l2tp-service /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 7 sheepdestroyer 2015-03-09 08:55:25 UTC
As proposed by se-troubleshooter, a while ago I did :

# grep nm-l2tp-service /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Since, I did not encounter the pb again so I will not be able to test effectiveness of this update.

Is there a way to undo the manual fix to then test your updated policy?
