ringbuf | Lock-free ring buffer | Runtime Evironment library

I'm looking for a method to send data from userspace to bpf program in Linux. I use libbpf in userspace and bpf_helpers in bpf program in kernel. I now can send data from kernel to user by ringbuf and other. but I want to use stack and queue for this. I can't find function that handles queue or stack in userspace and I still confused. My question is: how can I send data from userspace to bpf program using stack or queue and get it in my bpf program, as what we do in bcc with bpf['queue'].push in userspace for example and queue.peek(&val); in bpf program.

thank you for any help!
