It was later ported to BPF with kprobes, and has now been rewritten and included in commercial observability products. Unsurprisingly, I've heard it has problems on newer kernels, printing output that doesn't make sense. It really needs an overhaul. When I (or someone) does, anyone pulling...

During data transmission, Rover records each packet's through the network layers L2 to L4 using [kprobes](https://docs.kernel.org/trace/kprobes.html). This approach enhances the understanding of each packet's transmission process, facilitating easier localization and troubleshooting of network issues...
