Sorry for the late reply. I have some time to try it again.
I downloaded a fresh Ubuntu 19.10 image, which have bpftool included
from the linux-tools-generic package. Then tried to load a program
with 0 or 1 return code: both works.
After that I tried to load the original program, with return code
ibbpf guess the program type
correctly. So something definitely on my side - thank you for verifyng
that - I try to investigate it!

I found a strange error when I tried to load a BPF_CGROUP_INET_EGRESS
prog with bpftool. Loading the same program from C code with
bpf_prog_load_xattr works without problem.
The error message I got:
bpftool prog loadall hbm_kern.o /sys/fs/bpf/hbm type cgroup/skb
libbpf: load bpf progra
