alt Hacker NewsIn eBPF-land you're going to be calling C functions in the kernel, and using (generally) C data types like structs and null-terminated strings. You can't do loops (loops are unrolled by the compiler), you can't do variadic functions, and you definitely can't take advantage of all the cool Go stuff like goroutines, select, context, etc.
I'm not really sure why you'd want to use this. If you're writing eBPF, you already need to know how to read C kernel source.
It's the same situation with Aya in Rust. It's sort of a "same language on the backend and the frontend" kind of deal, like with Javascript.
I agree though, I think it makes more sense just to write the C code. The hard part of eBPF isn't writing the code; it's getting it past the verifier.
