Hello,
According to ushare_vm function, unsharing mm_struct has not been
implemented yet. Am I mistaken ?
static int unshare_vm(unsigned long unshare_flags, struct mm_struct **new_mmp)
{
struct mm_struct *mm = current->mm;
if ((unshare_flags & CLONE_VM) &&
(mm && atomic_read(&mm->mm_users) > 1)) {
return -EINVAL;
}
return 0;
}
Would it be enough to duplicate mm_struct here if i need usharing of VM ?
