Hello All,
Can anybody explain what is this function in this module doing. this
is newbie question but thank you for any help?
static int my_init_module(void)
{
if (verbose) {
printk(KERN_ALERT "Module %s has been loaded.\n", MYMODNAME);
}
/* matching process */
struct task_struct *p = NULL;
p = find_task_by_pid(1);
else {
struct thread_struct *thread = &p->thread;
struct vm86_struct *vm86 = NULL;
vm86 = thread->vm86_info;
/* vm86 = p->thread.vm86_info; */
pid_t mypid;
mypid = p->pid;
if (verbose)
printk(KERN_ALERT "process pid 1 init.\n");
printk(KERN_ALERT "printit: p = %p\n", p);
printk(KERN_ALERT "printit: The instruction pointer
for init is: %lu\n", KSTK_EIP(p));
printk(KERN_ALERT "printit: The stack pointer for init
is: %lu\n", KSTK_ESP(p));
printk(KERN_ALERT "printit: The fs register contains
%lu\n", thread->fs);
}
