Hi all, I seem to have a problem. I have a code which traps the sys_exit call in order to know about terminating threads . When upgrading to redhat 2.4.20-8 I cannot locate the sys_exit , sys_socketcall which helped hacking into the syscall table , does anyone know about a solution , or any other way I can follow terminating threads in my system. The hack code is the following : begin = (unsigned long *) &system_utsname; for (i=0;i<1024;i++) { if (*(begin+i) == (unsigned long) sys_socketcall) { sys_call_table = (void *) (begin+i-__NR_socketcall); //are you sure? if (sys_call_table[__NR_exit]==(void *) sys_exit) { Status = PAKRNL_STATUS_SUCCESS; } } } Koby -- Kernelnewbies: Help each other learn about the Linux kernel.
