We are working on a project to enhance linux /proc.
This is of particular importance to the 'Paradayn'
project (cs.wisc.edu/paradyn).
We want to add the ability to specifically trace a
set of system calls and the ability to trace the
system call entry or exit or both. For this we wanted
to add two structs to
struct task_struct in include/linux/sched.h
struct syscall_set {
char traced[8];
}
we want to add
struct syscall_set entry,exit; to task_struct in
include/linux/sched.h
In the beginning of task_struct we found that
struct task_struct {
/*
* offsets of these are hardcoded elsewhere - touch
with care
*/
We want to know what we would be breaking if
we add the structs at the end ? (so that we can fix
them)
Also how do we initialize it in
#define INIT_TASK(tsk) (we want to set all bits in the
struct to 1).
Thanks,
George
