I made good progress, see
https://gitlab.com/metze/socket_wrapper/-/commits/fd-passing-unix
https://gitlab.com/metze/socket_wrapper/-/pipelines/161689331

And for Samba:
https://git.samba.org/?p=metze/samba/wip.git;a=shortlog;h=refs/heads/master-multichannelhttps://gitlab.com/samba-team/devel/samba/-/pipelines/161691424
https://gitlab.com/samba-team/devel/samba/-/pipelines/161691541

I'll add some more tests tomorrow and debug why some samba tests are
failing...
