Hi Mulyadi, You were right. I found this code, which is called from ptrace_attach function: http://lxr.free-electrons.com/source/kernel/ptrace.c#L41 Thanks :) On 27 February 2012 08:45, Vimal <j.vimal@gmail.com> wrote:

I am bit rusty here, but AFAIK sigchld is thrown to the process who ptrace another process. CMIIW
sigchld's definition [1] says it's sent to the parent process when a child terminates.
But I do agree that the notion of a parent seems a bit ambiguous when a process is being ptraced.
ptrace is what I found when looking through some websites, and you may very well be correct. But as always, it is good to confirm through code. :) Let me try checking the ptrace functions.
Thanks! -- Vimal
