To prevent this case, one rule of the simple set of rules would be "Use automatic variables only within the function where it is defined". Other may be "Take the address of objects only if the object is defined in the DS segment". It will be necessary a heap to allocate data in DS for you example. The question is: using an adequate kmalloc() and a simple set of rules, can we get a functional kernel? -- To unsubscribe from this list: send the line "unsubscribe linux-8086" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
