Thank you Greg and others advising on my first question. I am writing monitor sybsytem, abd here the question : Is it possible from kernel module or user space to monitor which processes were terminated abnormally ? I understand that trap gates are initialized to handle it , fill trap_info, then sig_info and send signal to faulting process. Is it correct to place a hook in these chain? probably in signal.c : next_signal()? If so what is the proper method, ex jprobe?
