Sorry, bcc does not support kfunc. It need some effort to implement it. libbpf-tools supports kfunc. |

I'm trying to write BPF code that calls a kfunc (by kfunc I mean "kernel function callable from BPF", not "kernel function hooked by BPF"); but I can't figure out how to make that work. When I declare the kfunc as an extern function with
__attribute__((section(".kyms")))and call it, I get a compiler error saying "cannot call non-static helper function". Is it just not possible to call kfuncs from code built with bcc, or am I doing it wrong?Beta Was this translation helpful? Give feedback.
