| [[https://github.com/cilium/pwru|pwru]] is a tool created by Cilium to help trace network packets in the kernel's network stack and debug network connectivity issues. It does this by attaching simple eBPF programs to certain function entry points. These programs can report back to a userspace process different kinds of information, including the function that was reached, the arguments that were passed, and a CPU clock timestamp. The method used for instrumenting kernel code is based on [[https://www.kernel.org/doc/html/latest/trace/kprobes.html|kprobes]]. Ask your assistant for more information. | [[https://github.com/cilium/pwru|pwru]] is a tool created by Cilium to help trace network packets in the kernel's network stack and debug network connectivity issues.
