High-end memory refers to memory with a physical address greater than 896M. For such memory, it is not possible to map in "Kernel Direct mapping Space".Why?Because "kernel direct mapping Space" can only be from 3G to 4G, only directly mapped 1G physical memory, for more than 1G of physical

And through the use of a unique set of technologies (SCI technology and mutation testing, etc.), thoroughly examine and test our code, pinpoint the exact location of the error and give detailed diagnostic information.

Recently engaged in a number of software security aspects of the online public class resources to integrate, this work will be launched in October this year. So far, I've done a buffer overflow, formatted string attack and some other C-language weaknesses in the material collection. After giving these materials, I want to ask, "What do these mistakes have in common?" The answer is that they all violate the principle of memory security. Next I will exp

reference itself, then the vector still references the object, so the object is not recyclable to the GC. Therefore, if the object has to be removed from the vector after it has been added to the vector, the simplest way is to set the vector object to null.Vector v=new vector (int i=1;iAt this point, all object objects are not freed because the variable v refers to these objects.Back to top of pageHow to detect memory leaksThe last important question

Wow, it's been a long time since it's been updated, let's talk about Linux's memory mechanism today.First, let's take a look at the conceptFirst, what is the memory mechanism of Linux?We know that reading and writing data directly from physical memory is much faster than reading and writing data from a hard disk, so we want all of the data read and written to be

set the vector object to null. Vector v = new vector (10 );For (INT I = 1; I {Object o = new object ();V. Add (O );O = NULL;}// At this time, all object objects are not released because variable v references these objects. 4. How to detect memory leakage The last important issue is how to detect Java memory leaks. Currently, we usually use some tools to check the memor
