Bug: program kprobe_skb_2: load program: permission denied

[Lan-ce-lot]

When I used the pwru on the machine, I had an error:

# sudo ./pwru 'dst host 127.0.0.1 and icmp'
...
program kprobe_skb_2: load program: permission denied: invalid indirect read from stack off -40+0 size 8 (10961 line(s) omitted)

# uname -a
Linux  5.4.119-19-0008 #1 SMP Mon Sep 13 14:54:39 CST 2021 x86_64 x86_64 x86_64 GNU/Linux
# ./pwru --version
pwru v1.0.6

How should I check this question?

It's weird since we have 5.4 kernel covered in CI 😹 😭

Would you like to try a newer version of kernel? 5.4.119 was released on 14-May-2021, a bit out of date (

Otherwise, can you provide the complete error log?
