Hi
Disclaimer:
I am trying to create a new port (knot-resolver-current) developed under Linux
upstream. A so-called manager functionality is brand new in comparison to the
previous knot-resolver. The corresponding git repository is leading edge
development.
My main motivation is: learning how to create ports ;-)

Both SO_PASSCRED and SCM_CREDENTIALS aren't defined in the complete git
repository.
Is there a way to include Linux compatibility regarding sockets?
Thanks and regards,
