"We should start back", Gared urged as the woods began to grow dark around them. "The wildings are dead". "Do the dead frighten you"? Ser Waymar Royce asked with just the hint of a smile. Gared did not rise to the bait. He wa

Dynamic dispatch动态调度.动态分发 In computer science, dynamic dispatch is the process of selecting which implementation of a polymorphic operation (method or function) to call at run time. It is commonly employed in, and considered a prime characteristic of

我在博客上发表一些我的Android学习心得,希望对大家能有帮助. 这一篇我们讲述一下通过一个实例来分析dex文件结构和组成. 参考Leb128数据类型 Android学习心得(5) --- dex数据类型LEB128 参考实例分析学习理解dex文件结构Android学习心得(15) --- Dex文件结构解析(1) 参考baksmali工具使用Android学习心得(4) --- MAC下smali文件编写与运行 1.编译 我们通过一个例子来分析dex文件的构成 创建一个Hello.java文

为了进行代码及产品保护,几乎所有的非开源App都会进行代码混淆,这样当收集到崩溃信息后,就需 要进行符号化来还原代码信息,以便开发者可以定位Bug.基于使用SDK和NDK的不同,Android的崩溃分为两类:Java崩溃和C/C++崩溃.Java崩溃通过mapping.txt文件进行符号化,比较简单直观,而C/C++崩溃的符号化则需要使用Google自带的一些NDK工具,比如ndk-stack.addr2line.objdump等.本文不去讨论如何使用这些工具,有兴趣的朋友可以参考同事写的另一篇

lab1 中的Makefile主要是根目录下的GNUMakefile, kern/Makefrag, boot/Makefrag, 后两者通过include直接包含到GNUMakefile中. 1 # 2 # This makefile system follows the structuring conventions 3 # recommended by Peter Miller in his excellent paper: 4 # 5 # Recursive Make Considere

This document is the user manual for the Yasm assembler. It is intended as both an introduction and a general-purpose reference for all Yasm users. 1.?Introduction Yasm is a BSD-licensed assembler that is designed from the ground up to allow for mult

依稀记得第一次接触Hook的概念是在周伟民先生的书中-><<多任务下的数据结构与算法>>,当时觉得Hook的本质就是拦截,就算到现在也是如此认为. 本篇文章是在x86下测试与分析跳转+offset类型的Hook,并且逆推测出热补丁的简单用法,MinHook它的中心就是覆盖重写并且可以复原.知道大概的思路后后让我们先来具体的实现MinHook再去做测试. 首先是堆的申请,这是必要也必须做的,对于微软函数HeapCreate()就不再赘述,以下是实现与卸载 1 NTSTATUS
