Debug Windows Drivers — Step by Step Lab (Echo Kernel-Mode)

This lab introduces the WinDbg kernel debugger. WinDbg is used to debug the echo kernel mode sample driver code.

Lab objectives

This lab includes exercises that introduce the debugging tools, teach common debugging commands, illustrate the use of break points, and show the use of the debugging extensions.

In this lab, a live kernel debug connection is used to explore the following:

• Use the Windows debugger commands
• Use standard commands (Call stacks, variables, threads, IRQL)
• Use advanced driver debugging commands (!commands)
• Use symbols
• Set breakpoints in live debugging
• View call stacks
• Display the Plug and Play device tree
• Work with thread and process context

Note When working with the Windows debugger, there are two types of debugging that can be performed — user or kernel mode debugging.

User mode — Applications and subsystems run on the computer in user mode. Processes that run in user mode do so within their own virtual address spaces. They are restricted from gaining direct access to many parts of the system, including system hardware, memory that was not allocated for their use, and other portions of the system that might compromise system integrity. Because processes that run in user mode are effectively isolated from the system and other user mode processes, they cannot interfere with these resources.

Kernel mode — Kernel mode is the processor access mode in which the operating system and privileged programs run. Kernel mode code has permission to access any part of the system, and is not restricted like user mode code. It can gain access to any part of any other process running in either user mode or kernel mode. Much of the core OS functionality and many hardware device drivers run in kernel mode.

This lab will focus on kernel mode debugging, as that is the method used to debug many device drivers.

This exercise covers debug commands that are frequently used during both user-mode and kernel-mode debugging. The exercise also covers debug extensions (sometimes called «!commands») that are used for kernel-mode debugging.

Lab setup

You will need the following hardware to be able to complete the lab.

• A laptop or desktop computer (host) running Windows 10
• A laptop or desktop computer (target) running Windows 10
• A network hub/router and network cables to connect the two PCs
• Access to the internet to download symbol files

You will need the following software to be able to complete the lab.

• Visual Studio
• Windows Software Development Kit (SDK) for Windows 10
• Windows Driver Kit (WDK) for Windows 10
• The sample echo driver for Windows 10

The lab has the following eleven sections.

Section 1: Connect to a kernel mode WinDbg session

In Section 1, you will configure network debugging on the host and target system.

The PCs in this lab need to be configured to use an Ethernet network connection for kernel debugging.

This lab uses two PCs. Windows debugger runs on the host system and the KMDF Echo driver runs on the target system.

Use a network hub/router and network cables to connect the two PCs.

To work with kernel mode applications and use WinDbg, we recommend that you use the KDNET over Ethernet transport. For information about how to use the Ethernet transport protocol, see Getting Started with WinDbg (Kernel-Mode). For more information about setting up the target computer, see Preparing a Computer for Manual Driver Deployment and Setting Up KDNET Network Kernel Debugging Automatically.

Configure kernel–mode debugging using ethernet

To enable kernel mode debugging on the target system, perform the following steps.

On the target system

1. Open a command prompt on the target system and use the ping command to confirm network connectivity between the two systems. Use the actual IP address of the host system you recorded instead of 169.182.1.1 that is shown in the sample output.

Enable kernel mode debugging on the target system by completing the following steps.

Before using BCDEdit to change boot information you may need to temporarily suspend Windows security features such as BitLocker and Secure Boot on the test PC. Re-enable these security features when testing is complete and appropriately manage the test PC, when the security features are disabled.

On the target computer, open a Command Prompt window as Administrator. Enter this command to enable debugging.

Type this command to enable test signing.

Type this command to set the IP address of the host system. Use the IP address of the host system that you recorded earlier, not the one shown.

Warning To increase the security of the connection and decrease the risk of the random client debugger connection requests, consider using an auto generated random key. For more information, see Setting Up KDNET Network Kernel Debugging Automatically.

Type this command to confirm that the dbgsettings they are set properly.

Note
Firewalls and debuggers

If you receive a pop-up message from the firewall, and you wish to use the debugger, check all three of the boxes.

On the target system

Reboot the target system.

Section 2: Kernel mode debugging commands and techniques

In Section 2, you will use debug commands to display information about the target system.

Section 3: Download and build the KMDF echo driver

In Section 3, you will download and build the KMDF echo driver.

Typically, you would be working with your own driver code when you use WinDbg. To become familiar with WinDbg operation, the KMDF Template «Echo» sample driver is used. With the source code available, it will also be easier to understand the information that is displayed in WinDbg. In addition, this sample is used to illustrate how you can single step through native kernel mode code. This technique can be very valuable for debugging complex kernel mode code issues.

To download and build the Echo sample audio driver, perform the following steps.

Download and extract the KMDF Echo sample from GitHub

You can use a browser to view the echo sample in GitHub here:

You can read about the sample here:

You can browse all of the Windows driver samples here:

The KMDF Echo sample is located in the general folder.

a. This lab, shows how to download the driver samples in one zip file.

b. Download the master.zip file to your local hard drive.

c. Select and hold (or right-click) Windows-driver-samples-master.zip, and choose Extract All. Specify a new folder, or browse to an existing one that will store the extracted files. For example, you could specify C:\DriverSamples\ as the new folder into which the files are extracted.

d. After the files are extracted, navigate to the following subfolder.

Open the driver solution in Visual Studio

In Microsoft Visual Studio, select File > Open > Project/Solution. and navigate to the folder that contains the extracted files (for example, C:\DriverSamples\general\echo\kmdf). Double-click the kmdfecho solution file to open it.

In Visual Studio, locate the Solution Explorer. (If this is not already open, choose Solution Explorer from the View menu.) In Solution Explorer, you can see one solution that has three projects.

Set the sample’s configuration and platform

In Solution Explorer, select and hold (or right-click) Solution ‘kmdfecho’ (3 projects), and choose Configuration Manager. Make sure that the configuration and platform settings are the same for the three projects. By default, the configuration is set to «Win10 Debug», and the platform is set to «Win64» for all the projects. If you make any configuration and/or platform changes for one project, you must make the same changes for the remaining three projects.

Set the runtime library

Set the runtime library — Open the echo driver’s property page and locate C/C++ > Code Generation. Change Runtime Library from DLL version to non DLL version. Without this setting, you have to install the MSVC runtime to the target computer separately.

Check driver signing

Also on the driver’s properties make sure Driver Signing > Sign Mode is set to “Test Sign”. This is required because Windows requires that drivers are signed.

Build the sample using Visual Studio

In Visual Studio, select Build > Build Solution.

If all goes well, the build windows should display a message indicating that the build for all three projects succeeded.

Locate the built driver files

In File Explorer, navigate to the folder that contains the extracted files for the sample. For example, you would navigate to C:\DriverSamples\general\echo\kmdf, if that’s the folder you specified earlier. Within that folder, the location of the compiled driver files varies depending on the configuration and platform settings that you selected in the Configuration Manager. For example, if you left the default settings unchanged, then the compiled driver files will be saved to a folder named \x64\Debug for a 64 bit, debug build.

Navigate to the folder that contains the built files for the Autosync driver:

The folder should contain these files:

File	Description
Echo.sys	The driver file.
Echo.inf	An information (INF) file that contains information needed to install the driver.

In addition, the echoapp.exe file was built and it should be located here: C:\DriverSamples\general\echo\kmdf\exe\x64\Debug

File	Description
EchoApp.exe	A command prompt executable test file that communicates with the echo.sys driver.

Locate a USB thumb drive or set up a network share to copy the built driver files and the test EchoApp from the host to the target system.

In the next section, you will copy the code to the target system, and install and test the driver.

Section 4: Install the KMDF echo driver sample on the target system

In Section 4, you will use devcon to install the echo sample driver.

The computer where you install the driver is called the target computer or the test computer. Typically, this is a separate computer from the computer on which you develop and build the driver package. The computer where you develop and build the driver is called the host computer.

The process of moving the driver package to the target computer and installing the driver is called deploying the driver.

Before you deploy a test signed driver, you must prepare the target computer by enabling test signing. You also need to locate the DevCon tool in your WDK installation and copy that to the target system.

To install the driver on the target system, perform the following steps.

-> On the target system

Enable test signed drivers

Enable the ability to run test signed drivers:

a. Open Windows Settings.

b. In Update and Security, select Recovery.

c. Under Advanced startup, select Restart Now.

d. When the PC reboots, select Startup options. In Windows 10, select Troubleshoot > Advanced options > Startup Settings , then select Restart button.

e. Select Disable driver signature enforcement by pressing the F7 key.

f. Reboot the target computer.

On the target system

On the target computer, select and hold (or right-click) the certificate file, and select Install, then follow the prompts to install the test certificate.

If you need more detailed instructions for setting up the target computer, see Preparing a Computer for Manual Driver Deployment.

-> On the target system

Install the driver

The following instructions show you how to install and test the sample driver. Here’s the general syntax for the devcon tool that you will use to install the driver:

The INF file required for installing this driver is echo.inf. The inf file contains the hardware ID for installing the echo.sys. For the echo sample the hardware ID is root\ECHO.

On the target computer, open a Command Prompt window as Administrator. Navigate to your driver package folder, and enter the following command:

devcon install echo.inf root\ECHO If you get an error message about devcon not being recognized, try adding the path to the devcon tool. For example, if you copied it to a folder called C:\Tools, then try using the following command:

c:\tools\devcon install echo.inf root\ECHO A dialog box will appear indicating that the test driver is an unsigned driver. Select Install this driver anyway to proceed.

В If you have any issues with the installation, check the following file for more information. %windir%\inf\setupapi.dev.log

After successfully installing the sample driver, you’re now ready to test it.

Examine the driver in Device Manager

On the target computer, in a Command Prompt window, enter devmgmt open Device Manager. In Device Manager, on the View menu, choose Devices by type. In the device tree, locate Sample WDF Echo Driver in the Sample Device node.

Test the driver

Type echoapp to start the test echo app to confirm that the driver is functional.

Section 5: Use WinDbg to display information about the driver

In Section 5, you will set the symbol path and use kernel debugger commands to display information about the KMDF echo sample driver.

View information about the driver by performing the following steps.

x ECHO!Echo* to display information about all of the symbols associated with echo driver that start with Echo.

The !lmi extension displays detailed information about a module. Type !lmi echo. Your output should be similar to the text shown below.

Use the !dh extension to display header information as shown below.

Setting the debug mask

Type the following to change the default debug bit mask so that all debug messages from the target system will be displayed in the debugger.

Some drivers will display additional information when the mask of 0xFFFFFFFF is used. Set the mask to 0x00000000 if you would like to reduce the amount of information that is displayed.

Use the dd command to display confirm the mask is set to display all of the debugger messages.

Section 6: Displaying Plug and Play device tree information

In Section 6, you will display information about the echo sample device driver and where it lives in the Plug and Play device tree.

Information about the device driver in the Plug and Play device tree can be useful for troubleshooting. For example, if a device driver is not resident in the device tree, there may an issue with the installation of the device driver.

For more information about the device node debug extension, see !devnode.

Section 7: Working with breakpoints and source code

In Section 7, you will set breakpoints and single step through kernel mode source code.

Note
Setting breakpoints using commands

To be able to step through code and check the values of variables in real time, we need to enable breakpoints and set a path to the source code.

Breakpoints are used to stop code execution at a particular line of code. You can then step forward in the code from that point, to debug that specific section of code.

To set a breakpoint using a debug command, use one of the following b commands.

Sets a breakpoint that will be active until the module it is in is unloaded.

Sets a breakpoint that is unresolved when the module is unloaded and re-enables when the module reloads.

Sets a breakpoint for a symbol. This command will use bu or bp appropriately and allows wildcards * to be used to set breakpoints on every symbols that matches (like all methods in a class).

For more information, see Source Code Debugging in WinDbg in the debugging reference documentation.

Source Mode is enabled in the current WinDbg session.

Add your local code location to the source path by typing the following command.

Add your local symbol location to the symbol path by typing the following command.

We will use the x command to examine the symbols associated with the echo driver to determine the function name to use for the breakpoint. We can use a wild card or Ctrl+F to locate the DeviceAdd function name.

The output above shows that DeviceAdd method for our echo driver is ECHO!EchoEvtDeviceAdd.

Alternatively, we could review the source code to locate the desired function name for our breakpoint.

Set the breakpoint with the bm command using the name of the driver, followed by the function name (for example AddDevice) where you want to set the breakpoint, separated by an exclamation mark. We will use AddDevice to watch the driver being loaded.

Note
You can use different syntax in conjunction with setting variables like ! , :: ,‘ :
’, or skip a number of times . For more information, see Conditional breakpoints in WinDbg and other Windows debuggers.

List the current breakpoints to confirm that the breakpoint was set by typing the bl command.

The «e» in the output shown above indicates that the breakpoint number 1 is enabled to fire.

Restart code execution on the target system by typing the go command g.

-> On the target system

In Windows, open Device Manager using the icon or by entering mmc devmgmt.msc. In Device Manager, expand the Samples node.

Select and hold (or right-click) the KMDF Echo driver entry and select Disable from the menu.

Select and hold (or right-click) the KMDF Echo driver entry again and select Enable from the menu.

Clears a breakpoint from the list. Use bc * to clear all breakpoints.

Disables a breakpoint. Use bd * to disable all breakpoints.

Enables a breakpoint. Use be * to enable all breakpoints.

Alternatively, you can also modify breakpoints by selecting edit > breakpoints in WinDbg. Note that the breakpoint dialog box only works with existing breakpoints. New breakpoints must be set from the command line.

Note
Setting memory access breakpoints

You can also set breakpoints that fire when a memory location is accessed. Use the ba (break on access) command, with the following syntax.

execute (when CPU fetches an instruction from the address)

read/write (when CPU reads or writes to the address)

write (when the CPU writes to the address)

Note that you can only set four data breakpoints at any given time and it is up to you to make sure that you are aligning your data correctly or you won’t trigger the breakpoint (words must end in addresses divisible by 2, dwords must be divisible by 4, and quadwords by 0 or 8).

For example, to set a read/write breakpoint on a specific memory address, you could use a command like this.

Note
Stepping through code from the Debugger Command window

The following are the commands that you can use to step through your code (with the associated keyboard short cuts shown in parentheses).

Break in (Ctrl+Break) — This command will interrupt a system as long as the system is running and is in communication with WinDbg (the sequence in the Kernel Debugger is Ctrl+C).

Run to cursor (F7 or Ctrl+F10) – Place the cursor in a source or disassembly window where you want the execution to break, then press F7; code execution will run to that point. Note that if the flow of code execution does not reach the point indicated by the cursor (an IF statement isn’t executed), WinDbg would not break, because the code execution did not reach the indicated point.

Run (F5) – Run until a breakpoint is encountered or an event like a bug check occurs.

Step over (F10) – This command causes code execution to proceed one statement or one instruction at a time. If a call is encountered, code execution passes over the call without entering the called routine. (If the programming language is C or C++ and WinDbg is in source mode, source mode can be turned on or off using Debug>Source Mode).

Step in (F11) – This command is like step-over, except that the execution of a call does go into the called routine.

Step out (Shift+F11) – This command causes execution to run to and exit from the current routine (current place in the call stack). This is useful if you’ve seen enough of the routine.

For more information, see Source Code Debugging in WinDbg in the debugging reference documentation.

Section 8: Viewing variables and call stacks

In Section 8, you will display information about variables and call stacks.

This lab assumes that you are stopped at the AddDevice routine using the process described earlier. To view the output show here, repeat the steps described previously, if necessary.

local menu item to display local variables.

Global variables

You can find the location of a global variable address by typing ? .

Local variables

You can display the names and values of all local variables for a given frame by typing the dv command.

Callstacks

Note
The call stack is the chain of function calls that have led to the current location of the program counter. The top function on the call stack is the current function, and the next function is the function that called the current function, and so on.

To display the call stack, use the k* commands.

Displays the stack and first three parameters.

Displays the stacks and the full list of parameters.

Allows you to see the stack with the frame information next to it.

call stack to view it. Select the columns at the top of the window to toggle the display of additional information.

1. Use the kn command to show the call stack while debugging the sample adapter code in a break state.

The call stack shows that the kernel (nt) called into Plug and Play code (PnP), that called driver framework code (WDF) that subsequently called the echo driver DeviceAdd function.

Section 9: Displaying processes and threads

Processes

In Section 9, you will display information about the process and threads running in kernel mode.

Note
You can display or set process information by using the !process debugger extension. We will set a breakpoint to examine the process that are used when a sound is played.

On the target system

Run the EchoApp.exe driver test program on the target system.

Note
The commands to view and set threads are very similar to those of processes. Use the !thread command to view threads. Use .thread to set the current threads.

On the target system

Run the EchoApp.exe driver test program on the target system.

Section 10: IRQL, Registers and Ending the WinDbg session

Viewing the saved IRQL

In Section 10, you will display the IRQL, and the contents of the regsisters.

Viewing the registers

registers. For more information see r (Registers).

Viewing the contents of the registers can be helpful when stepping through assembly language code execution and in other scenarios. For more information about assembly language disassembly, see Annotated x86 Disassembly and Annotated x64 Disassembly.

For information about contents of the register, see x86 Architecture and x64 Architecture.

Ending the WinDbg session

Section 11: Windows debugging resources

Additional information is available on Windows debugging. Note that some of these books will use older versions of Windows such as Windows Vista in their examples, but the concepts discussed are applicable to most versions of Windows.
