Do unix(7) sockets with cmsg(UCM_RIGHTS) not give you what you want?
You can have a cookie process sitting in user space waiting on a UNIX socket. When somebody passes you the right cookie string, you send them a file descriptor.

P.S. I had to look a bit for cmsg(UCM_RIGHTS). I was more familiar with ioctl(I_SENDFD), which it appears that Linux does not implement.
