You can call external functions in a bpf program but they must be registered first. [register_functions](https://github.com/iovisor/ubpf/blob/5b5763639a8096c30257e51214636f544129380c/vm/test.c#L229)
Compile with `-O2` ``` root@cda22c35d683:~# cat prog.c static int (*sqrti)(int) = (void *)3; unsigned long int prog(char *addr) { return sqrti(16); } root@cda22c35d683:~# cat prog.s .text .file "prog.c" .globl prog...
You might be confusing `prog` and `prog.o`
You are welcome ! :D
