小弟学习Android逆向也有一段时间,翻看大神们的帖子收获了不少,开始对ELF、so文件很感兴趣,尤其对内存dump和修复的技术很好奇,看了ThomasKing的ELF section修复的帖子更是深受启发,链接:http://www.52pojie.cn/thread-294642-1-1.html,通过帖子中给出的修复思路,再配合一篇关于ELF文件结构解析的文章让小弟完整立体的了解ELF的文件结构和加载运行等机制,出于好奇想知道这个SECTION的修复具体的实现,但是大神没有给出源码,在网上搜索也没有人在这方面提供资料,因此就决定通过这篇帖子给出的思路,自己实现一个section修复工具,顺便也学习一下elf文件
0x0002
其实TomasKing大大的帖子中已经把思路都写得很清楚了,但在实现时确实有一些坑,小弟当时天真的认为shstrtab这个section会在dump下的文件中找到,结果发现根本没有,这里需要自己写一个shstrtab然后添加在section header 尾部,这一点可能是我最大的收获了,还有一个问题就是大神说道”通过__global_offset_table 偏移 + 4 * (rel.plt.size) / sizeof(Elf32_Rel)(这里还需要添加2个int的填充位置)得到got的末尾“ 实际是添加了3个int的填充位,这里不知道大神写错了还是程序之间的差异。下面就给我源码吧 代码比较挫看的时候大家忍一忍 有不对的地方请大家斧正
