Description of problem:
I added user 'user' in Fedora docker container. Then run 'su - user' inside container. This caused the AVC on Host
SELinux is preventing su from 'link' accesses on the key Unknown.

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

If you believe that su should be allowed link access on the Unknown key 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 su /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
