Re: math between pkt pointer and register with unbounded min value is not allowed #verifier

Thx a lot for your time Jiong.

The more I played with bpf/xdp, the more I understand that the challenge is about making "optimized byte code" compliant for the verifier.

How could I do this kind of checks my self ? I mean looking how llvm optimized my code ? (to be able to do same kind of analyses you do above?)
