Hi folks, I want to organize my BPF programs so that I can load them individually. I want this so that if loading one fails (because of lack of kernel support for BPF features), I can load a fall-back replacement program. To do so, I've organized the BPF programs into their own source code files and compiled them individually. Each BPF program references what is supposed to be the same ringbuffer. Using libbpf I open them and attempt to load each in order. My question is, how am I supposed to share maps such as ringbuffers between them? If I have identical map definitions in each, they have their own file descriptors. Is the best way to call `bpf_map__reuse_fd()` on each handle of the maps in each BPF object? I'd also take advice on how to better achieve my overall goal of being able to load programs individually! Thanks so much for your help, Grant Seltzer
