Description Mirek Svoboda 2017-07-05 14:46:32 UTC
Description of problem:
on FC26, with strongswan-5.5.3, while starting strongswan
Tried both with the same effect:
1. under regular user with
sudo systemctl start strongswan
the user has sudoers rights to run systemctl

2. under root
systemctl start strongswan

Running strongswan from command line as root works well.
SELinux is preventing starter from 'execute_no_trans' accesses on the file /usr/libexec/strongswan/charon.

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

If you believe that starter should be allowed execute_no_trans access on the charon 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 'starter' --raw | audit2allow -M my-starter
# semodule -X 300 -i my-starter.pp
