I often cite this diagram: https://upload.wikimedia.org/wikipedia/commons/3/37/Netfilter-packet-flow.svg https://upload.wikimedia.org/wikipedia/commons/3/37/Netfilte... as my favorite picture. It shows the logical flow of packets through Linux. I'm pretty sure my career would be on a very different trajectory had I not discovered an earlier version of it back in ~2006.
- CurleighBraces 4y agoThis is great. Don't suppose you've seen anything similar for the flow when you include SR-IOV/DPKD a google didn't help.
- sophacles 4y agoSadly I have not. I've been on the lookout though. I've also considered adding annotations for ebpf hooks to this one, but that turns out to be rather difficult to keep up with too.
- suncore 4y agoDPDK/SRIOV eats the interface so Linux kernel does not see it at all. The above diagram is kind of irrelevant as it would look like a giant bypass.
