Hi, There is something I didn't get so much about compiling a bpf object.To compile my code for bpf, I need to include some headers from the kernel, which sounds OK.
On my debian, I understood this is something like this : -I/lib/modules/4.19.0-0.bpo.2-amd64/build/include -I/lib/modules/4.19.0-0.bpo.2-amd64/build/include/generated/uapi(Please tell me if I should include more headers or if this is the minimal set)
But I also need to to include some bpf helpers headers, generally called as bpf_helpers.h or bpf_endian.h. I didn't find this files in my distribution and I see a lot of open source examples/projects where those files are provided in the project itself... But as I understand the function helpers available depend of the bpf version and so the kernel version itself.
So why this is not available in my system kernel header ? Is it normal ? (all the distribution do that?)"adding this kind of file to my src tree for compilation" is the right thing to do ? (That sounds not so good ...)
I would really appreciate some hints to better understand that ! Thx Simon(my code is available here : https://github.com/sbernard31/udploadbalancer/tree/bpf_only_without_logs)
