Hi, >From https://www.collabora.com/news-and-blog/blog/2019/04/15/an-ebpf-overview-part-2-machine-and-bytecode/ "The BPF-accesible kernel "helper" functions are defined by the kernel core (not extensible through modules) via an API similar to defining syscalls" Has there been interest/discussion around having helper functions from kernel modules? Going through the code, I am guessing one of the obstacles is to have the verifier checking against helper functions that may or may not be available but I am not an expert of the subsystem. What are the current opinions on having helper functions from kernel modules? Regards, Kenny Ho
