Yes, I'm willing to work on this.

Hi
I'm new to ebpf and pwru.
I would like to work on this.
Any idea on how to begin?
Thanks

@varunkumare99 👋 This would require adding a new flag, and then passing all kernel module names from /sys/kernel/btf/ to the GetFuncs() function. No eBPF knowledge is required. Please let me know if you are willing to work on this, so that I can assign the issue to you.

I'm unable to run pwru with docker.

sudo docker run --privileged --rm -t --pid=host -v /sys/kernel/debug/tracing:/sys/kernel/debug/tracing cilium/pwru --filter-dst-ip=1.1.1.1

docker: Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "/sys/kernel/debug/tracing" to rootfs at "/sys/kernel/debug/tracing": mkdir /var/lib/docker/overlay2/c1572db5282c23f07099badddd4e2eabdc3afddc21f8ebd42be43faf357cd635/merged/sys/kernel/debug/tracing: no such file or directory: unknown.

For posterity, the fix was to run with:

sudo docker run --privileged --rm -t --pid=host -v /sys/kernel/debug/:/sys/kernel/debug/ cilium/pwru --filter-dst-ip=1.1.1.1
