Hello @vnik5287 I tested on my environment, and running recurring...

But the output is : `$ ./lucky0 xfrm 3.x - 5.x kernels poc vitaly [at] duasynt.com

[+] trying to win the race. wait... setaffinity: Invalid argument ` Kernel : 3.10.0-327

Is this expected? or not?

Thank You!

I encountered the similar situation but unshare instead of setaffinity:

$ ./lucky0
xfrm 3.x - 5.x kernels poc
