Description of problem:
When creating a new namespace, and add an interface to it, then dhcp in the new namespaces dhclient cli, the cli will fail.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Create an interface, e.g. a macvtap device, and a new namespaces including a new net namespaces.
2. Add the interface to the new namespaces
3. Up and dhcp the interface in the new namespaces

Actual results:
dhcp failed and the interface has not any IP addr.

Expected results:
The interface gets an IP addr, broadcast addr, ..., etc.

Additional info:

SELinux is preventing dhclient from net_bind_service access on the cap_userns Unknown.

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

If you believe that dhclient should be allowed net_bind_service access on the Unknown cap_userns 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 'dhclient' --raw | audit2allow -M my-dhclient
# semodule -X 300 -i my-dhclient.pp
