Windbg.exe的基础命令介绍


1 背景

工作多年，关于Windbg一直没有写过总结。为了以后查阅和方便分享，特写此文。

windbg.exe的优点就是绿色，体积小，速度快，功能强大。对于测试环境可以很快的部署。

一般情况，用windbg查死机非常方便。本文先介绍一下windbg常用的一些指令。


为了不涉密，选中一款开源软件做为调试目标。

2 调试目标

Notepad++.exe


3 源码&编译：

Notepad++ release 8.4.2.tar.gz

https://udomain.dl.sourceforge.net/project/notepadplusplus.mirror/v8.4.2/Notepad%2B%2B%20release%208.4.2.tar.gz


最新版本的Notepad++要求使用VS2019编译。这里不再介绍VS2019的安装.

VS2019编译Notepad++64位Release版本。编译结果如下：

clip_image002[4]


4 抓取DUMP

双击运行Notepad++.exe. 使用procdump.exe抓取一个DUMP

F:\Softwares\SysinternalsSuite_20211125>procdump.exe -ma -64 notepad++.exe

ProcDump v10.11 - Sysinternals process dump utility

Copyright (C) 2009-2021 Mark Russinovich and Andrew Richards

[17:01:34] Dump 1 initiated: F:\Softwares\SysinternalsSuite_20211125\notepad++.exe_220709_170134.dmp

[17:01:34] Dump 1 writing: Estimated dump file size is 118 MB.

[17:01:34] Dump 1 complete: 118 MB written in 0.3 seconds

[17:01:35] Dump count reached.


5 安装Windbg

下载Windbg.exe

https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/debugger-download-tools

clip_image004[4]

clip_image006[4]

不再演示安装的具体过程。


6 启动调试

由于编译的是Notepad++的64位版本，此处一定要使用64位的Windbg.exe。

调试器的位数要与DUMP的位数保持一致。32位的dump使用32位windbg调试，64位dump使用64位windbg调试。

7 加载符号

自行编译notepad++就是为了产生符号文件。下面的分析会用到符号的解析：

加载方法：File->Symbol File Path…

8.5 x命令：

查看模块notepad__的符号，x notepad__!*，直接输入此命令，符合太多。

本处做一些简单过滤，abc开头的没有，就看ab开头的。

0:000> x notepad__!abc*

0:000> x notepad__!ab*

00007ff7`04067230 notepad__!ablWordLists = char *[5]

00007ff7`040ef370 notepad__!abort_action = class __crt_state_management::dual_state_global<void (__cdecl*)(int)>

00007ff7`04067ac8 notepad__!abaqusWordListDesc = char *[7]

00007ff7`04033890 notepad__!AboutDlg::`vftable' = <function> *[16]

00007ff7`03e93f80 notepad__!AboutDlg::destroy (void)

00007ff7`03e0aff0 notepad__!AboutDlg::doDialog (void)

……


8.6 d命令：

查看内存数据。比如查看下AboutDlg的虚表内空。上图中，我们找们找到虚函数表的地址

00007ff7`04033890 notepad__!AboutDlg::`vftable' = <function> *[16]

根据C++的内存模型，我们查看下这个地址中存了什么内容？

使用d命令打印内存，但需要指定参数，a是ASCII字符串，b是字节，d是DWORD型，p是指针类型。

由于64位的内存是64位的，需要使用dp指令。

0:000> dp 00007ff7`04033890

00007ff7`04033890 00007ff7`03e8ed30 00007ff7`03e19e30

00007ff7`040338a0 00007ff7`03e93f80 00007ff7`03e227b0

00007ff7`040338b0 00007ff7`03e229f0 00007ff7`03e22a30
…


内存地址是打印出来了，那具体是什么函数呢？

在dp后面加上s，表示符号解析。效果如下：

0:000> dps 00007ff7`04033890

00007ff7`04033890 00007ff7`03e8ed30 notepad__!RecentFilesHistorySubDlg::`scalar deleting destructor'

…
00007ff7`040338f8 00007ff7`03c7fd00 notepad__!Scintilla::Internal::SurfaceD2D::Initialised [D:\Documents\source\Notepad++ release 8.4.2\notepad-plus-plus-notepad-plus-plus-a02a254\scintilla\win32\PlatWin.cxx @ 1430]

00007ff7`04033900 00007ff7`03e0b5e0 notepad__!AboutDlg::run_dlgProc [D:\Documents\source\Notepad++ release 8.4.2\notepad-plus-plus-notepad-plus-plus-a02a254\PowerEditor\src\WinControls\AboutDlg\AboutDlg.cpp @ 25]

00007ff7`04033908 00007ff7`040812e0 notepad__!DebugInfoDlg::`RTTI Complete Object Locator'


从上面的符号解析中，我们可以看到：AboutDlg继承了RecentFilesHistorySubDlg和Scintilla::Internal::SurfaceD2D等类。

对于Scintilla::Internal::SurfaceD2D这个类，查看下符号，我们看看其特殊之处：

0:000> x notepad__!Scintilla::Internal::SurfaceD2D*
00007ff7`0406c4c8 notepad__!Scintilla::Internal::SurfaceD2D::`vftable' = <function> *[2]
00007ff7`0406c898 notepad__!Scintilla::Internal::SurfaceD2D::`vftable' = <function> *[47]
00007ff7`03c83c18 notepad__!Scintilla::Internal::SurfaceD2D::Descent (class Scintilla::Internal::Font *)
00007ff7`03c72dd0 notepad__!Scintilla::Internal::SurfaceD2D::FlushCachedState (void)
……
00007ff7`03c81154 notepad__!Scintilla::Internal::SurfaceD2D::Stadium (class Scintilla::Internal::PRectangle *, class Scintilla::Internal::FillStroke *, Scintilla::Internal::Surface::Ends)
00007ff7`03c7fb04 notepad__!Scintilla::Internal::SurfaceD2D::SurfaceD2D (struct ID2D1RenderTarget *, int, int, struct Scintilla::Internal::SurfaceMode, int)
00007ff7`03c83d50 notepad__!Scintilla::Internal::SurfaceD2D::AverageCharWidth (class Scintilla::Internal::Font *)
……

看到没有，这个有两个虚拟表指针。说明是多继承.通过查看代码确实也可以证实这一点

class SurfaceD2D : public Surface, public ISetRenderingParams {
	SurfaceMode mode;

	ID2D1RenderTarget *pRenderTarget = nullptr;
	ID2D1BitmapRenderTarget *pBitmapRenderTarget = nullptr;
	bool ownRenderTarget = false;
	int clipsActive = 0;
...
}



8.7 u命令：

反汇编。

以上面输出的

00007ff7`03c7fb04 notepad__!Scintilla::Internal::SurfaceD2D::SurfaceD2D

为例进行说明。

00007ff7`03c7fb20 488901          mov     qword ptr [rcx],rax

通过上面的观察发现，可以通过地址来汇编，也可以通过符号进行反汇编。

通常情况下，当程序异常时会记录ExceptionAddress. 这个地址很有用。用它来汇编即可以找到出错代码的详细信息。


8.8 dt命令

查看变量的指令。从字面上面是d命令的变种。

比如静态变量

static const char * const apdlWordListDesc[] = {
    "processors",
    "commands",
    "slashommands",
    "starcommands",
    "arguments",
    "functions",
    0
};


通过符号找到静态变量的地址。根据这个地址打印出指针，根据指针即可以找到对应的字符串。

0:000> x notepad__!*apdlWordListDesc*
00007ff7`04068008 notepad__!apdlWordListDesc = char *[7]
0:000> dp 00007ff7`04068008

0:000> da 00007ff7`0407bbd8
00007ff7`0407bbd8  "processors"
0:000> da 00007ff7`0407bbc8
00007ff7`0407bbc8  "commands"



对于栈变量

由于栈在运行过程中，变量不断的压栈和出栈，这一部分信息不是静态的，无法追踪到历史信息，只能看到最新的栈变量信息.

建议使用工具栏的”调用栈”窗口，切换到栈。然后工具栏打开“局部变量”窗口，查看栈变量信息。如果下图所示：

image


对于堆变量

堆变量的查看，先要找到地址，可以从栈变量上下手，可以从静态变更下手，也可以从全局变量下手。只要能追踪到对应的指针地址就可以找到对应的值。


9. 示例:分析单例

对于大部程序中，都有一个全局变量，比如MFC中的theApp。或者一个单例，比如数据库实例或者配置实例。那么尝试从这个角度来追踪下，看看能不能查到更多的信息？


在main函数中，找到一个单例NppParameters，查看下符号，获取函数地址。

0:000> u notepad__!NppParameters::getInstance

根据上图的反汇编拿到了静态变量instance 的地址。由于instance 是一个指针，需要查看这个指针的内容。拿到对象NppParameters真正的地址。

class NppParameters final
{
private:
	static NppParameters* getInstancePointer() {
		static NppParameters* instance = new NppParameters;
		return instance;
	};

public:
	static NppParameters& getInstance() {
		return *getInstancePointer();
	};


根据真正的地址。按照 notepad__!NppParameters 进行解析。

dt notepad__!NppParameters 00000180`e0273830

0:000> dp 00007ff7`040db900
00007ff7`040db900  00000180`e0273830 00000000`80000001
00007ff7`040db910  00000001`00000000 00000000`00ffffff
00007ff7`040db920  00404050`00202030 00202030`00404050
……
0:000> dt notepad__!NppParameters 00000180`e0273830

   +0x038 _pXmlUserLangsDoc : std::vector<UdlXmlFileState,std::allocator<UdlXmlFileState> >
   +0x050 _pXmlToolIconsDoc : (null)
  
…


关这个命令的扩展

dt notepad__!NppParameters 00000180`e0273830

dt notepad__!NppParameters . 00000180`e0273830

增加一个点会展开一级显示，增加两个点会展开两级显示。
