I am trying to kill a specific process from the kernel (not in the user level) so I was trying to use sys_kill, kill, kill_pid but it did not work the only one did not give me an error is kill_pid but it did not kill the process that I asked so any help in that?

No you cant. You are in userspace. glibc or shell cant do that. That is why linux is more secure than windows. – Aizuddin Zali Oct 14 '15 at 17:47

Whatever code you are writing, you still executing it in userspace. You still use library to interact with kernel. In linux no direct access to kernel space. – Aizuddin Zali Oct 14 '15 at 18:09

Signal only works in userspace, so there is no way you can stop kernel thread
