Hi, I am working on this piece of code (simplified):
void ip_vma(struct task_struct *task, struct pt_regs *regs) { struct mm_struct *mm; struct vm_area_struct *vma;
if(task) { mm = get_task_mm(task); if(mm) { vma = find_vma(mm, regs->eip); if(vma) { /* Some code */ } else printk("WARNING: No VMA\n"); mmput(mm); } } }
I would like to get instruction pointer's VMA of a task. In order to do so, I use find_vma function, using regs->eip as instruction pointer value. Unfortunately I always get "WARNING: No VMA" message because find_vma isn't able to find the right VMA regs->eip address belongs to. Is regs->eip the right place where istruction pointer is located or I should find that value elsewhere?
Thank you,
