TAP-Windows driver (NDIS 6)

This is an NDIS 6.20/6.30 implementation of the TAP-Windows driver, used by
OpenVPN and other apps. NDIS 6.20 drivers can run on Windows 7 or higher except
on ARM64 desktop systems where, since the platform relies on next-gen power
management in its drivers, NDIS 6.30 is required.

Build

The prerequisites for building are:

• Python 2.7

• Microsoft Windows 10 EWDK (Enterprise Windows Driver Kit)

  • Visual Studio+Windows Driver Kit works too. Make sure to work from a «Command Prompt for Visual Studio» and to call buildtap.py with «—sdk=wdk».

• The devcon source code directory (setup/devcon) from Windows-driver-samples (optional)

  • If you use the repo from upstream remember to include our patch to devcon.vcxproj to ensure that devcon.exe is statically linked.

• Windows code signing certificate
• Git (not strictly required, but useful for running commands using bundled bash shell)
• MakeNSIS (optional)
• Prebuilt tapinstall.exe binaries (optional)
• Visual Studio 2019 and WiX Toolset for MSM packaging (optional)

Make sure you add Python’s install directory (usually c:\python27) to the PATH
environment variable.

Tap-windows6 has been successfully build on Windows 10 and Windows Server 2016 using
CMD.exe, Powershell and Git Bash.

  --versionoverride=FILE
                       Path to the version override file

Edit version.m4 and paths.py as necessary then build:

$ python buildtap.py -b

On successful completion, all build products will be placed in the «dist»
directory as well as tap6.tar.gz. The NSIS installer package will be placed to
the build root directory.

Building tapinstall (optional)

The easiest way to build tapinstall is to clone the Microsoft driver samples
and copy the source for devcon.exe into the tap-windows6 tree. Using PowerShell:

$ git clone https://github.com/OpenVPN/Windows-driver-samples.git
$ Copy-Item -Recurse Windows-driver-samples/setup/devcon tap-windows6
$ cd tap-windows6
$ python.exe buildtap.py -b --ti=devcon

The build system also supports reuse of pre-built tapinstall.exe executables.
To make sure the buildsystem finds the executables, create the following
directory structure under tap-windows6 directory:

devcon
├── Release
│   └── devcon.exe
├── x64
│   └── Release
│       └── devcon.exe
└── ARM64
    └── Release
        └── devcon.exe

This structure is equal to what building tapinstall would create. Then call
buildtap.py with «—ti=devcon». Replace «Release» with your build configuration;
for example, when using —Hlk you’d use «Hlk».

Please note that the NSIS packaging (-p) step will fail if you don’t have
tapinstall.exe available. Also don’t use the «-c» flag or the above directories
will get wiped before MakeNSIS is able to find them.

Developer Mode: Installing, Removing and Replacing the Driver

The driver can be installed using a command-line tool, tapinstall.exe, which is
bundled with OpenVPN and tap-windows installers. Note that in some versions of
OpenVPN tapinstall.exe is called devcon.exe. To install, update or remove the
tap-windows NDIS 6 driver follow these steps:

• place tapinstall.exe/devcon.exe to your PATH
• open an Administrator shell
• cd to dist
• cd to amd64, i386, or arm64 depending on your system’s processor architecture.

If you are actively developing the driver (e.g.: Edit, Compile, Debug, Loop…), you may not be signing your driver each time, thus you need to be aware of the following additional items.

Disable Secure Boot:

Unsigned drivers require disabling secure boot.

• Secure Boot: Varies depending on PC Maker and/or the BIOS setting on your test machine.
• https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/disabling-secure-boot
• VMWare (one example): https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vm_admin.doc/GUID-898217D4-689D-4EB5-866C-888353FE241C.html
• Virtual Box: SecureBoot is not supported on Virtual Box
• Parallels (MacOS) https://kb.parallels.com/en/124242 [With Parallels 15, it is enabled by default, use 0 to disable]

Enable Windows Test Mode:

Test mode is also required.

• Enable Windows Test Mode via BCEDIT
• For details: https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/bcdedit-command-line-options
• Specifically, bcdedit /set testsigning off or bcdedit /set testsigning on
• The result should be Test Mode in the bottom right corner of the windows screen.

Driver Installation:

Notes

• The command tapinstall install OemVista.inf TAP0901 installs the driver
• Because your driver is not signed, the tapinstall install step will pop up the «Big Scary Unsigned Driver Warning», you’ll need to click OK.
• As a result, the driver will be copied into the Windows Driver Store

Updating the Driver, and the Windows Driver Store:

At some point, you will build a shinny new driver and need to test it.

• The command tapinstall remove TAP0901 — removes the driver
• However, the previously approved driver is still in the Windows Driver Store
• Typing tapinstall install ... now, only re-installs the old driver that was copied into the driver store.

Key step: The driver needs to be removed from the driver store also.

• Details: https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/cc730875(v=ws.11)

There is a script to do this, but it only works if you have not changed the text strings in your driver package

• Script Location: https://github.com/mattock/tap-windows-scripts

The manual steps are:

• Step 1 — Obtain a list of Installed drivers via the command: pnputil -e, this will list all of the oemNUMBER.inf files that are in the driver store.
• Step 2 — Find your driver in that list, it will be some oem<NUMBER>.inf file
• Step 3 — To delete, use pnputil.exe /d oemNUMBER.inf

Finally use tapinstall install OemVista.inf TAP0901 to install your driver

Important:

If you do not see the Big Scary Unsigned Driver Warning — Windows will use the old (not new) driver.

Troubleshooting:

Examining the SetupAPI log file helps, see C:\Windows\INF\setupapi.dev.log.

Build for HLK tests

A test-signed version of tap-windows6 driver should be used for the HLK tests.
The recommended procedure is to use pre-built, cross-signed devcon.exe and use
the WDK-generated key for signing the driver.

First setup the directory with prebuilt devcon as described above.
Then run the build with the —hlk option:

$ python.exe buildtap.py -c -b --ti=devcon-prebuilt --hlk

Release process and signing

Microsoft’s driver signing requirements have tightened considerably over the
last several years. Because of this this buildsystem no longer attempts to sign
files by default. If you want to sign the files at build time use the —sign
option. The «sign» directory contains several Powershell scripts that help
produce release-signed tap-windows6 packages:

• Cross-Sign: cross-sign tap-windows6 driver files and tapinstall.exe
• Create-DriverSubmission: create architecture-specific attestation signing submission cabinet files
• Extract-DriverSubmission: extract attestation-signed zip files
• Sign-File: sign files (e.g. tap-windows6 installer or driver submission cabinet files)
• Sign-tap6.conf.ps1: configuration file for all the scripts above
• Prepare-Msm.ps1: take Win7- and Win10-signed «dist» directories and produce a «dist» directory that MSM packaging can consume

Most of these scripts operate directly on the «dist» directory that
tap-windows6 build system produces. Below it is assumed that building and
signing is done on the same computer.

First produce cross-signed drivers for (Windows 7/8/8.1/Server 2012r2):

$ python.exe buildtap.py -c -b --ti=devcon
$ sign\Cross-Sign.ps1 -SourceDir dist -Force

Note that the «-Force» option for Cross-Sign.ps1 is required except in the
unlikely case that you’re appending a signature.

Next produce a driver submission cabinet files for attestation signing:

$ sign\Create-DriverSubmission.ps1
$ Get-ChildItem -Path disk1|sign\Sign-File.ps1

Three architecture-specific (i386, amd64, arm64) cabinet files are created.
Submit these to Windows Dev Center for attestation signing. Note that unsigned
cabinet files will be automatically rejected.

When submitting the drivers to Microsoft take care to only request signatures
applicable for each architecture.

At this point move the cross-signed «dist» directory away:

$ Move-Item dist dist.win7

Download the attestation-signed drivers as zip files put them into a temporary
directory (e.g. tap-windows6tempdir). Then run Extract-DriverSubmission.ps1:

$ Get-ChildItem -Path tempdir -Filter "*.zip"|sign\Extract-DriverSubmission.ps1

This extracts the drivers into the «dist» directory. Move that directory to dist.win10:

$ Move-Item dist dist.win10

After this you can start creating the installers and/or MSM packages.

If you’re creating NSIS packages do:

$ Move-Item dist.win7 dist
$ python.exe buildtap.py -p --ti=devcon
$ Move-Item dist dist.win7

Followed by:

$ Move-Item dist.win10 dist
$ python.exe buildtap.py -p --ti=devcon
$ Move-Item dist dist.win10

Finally sign both installers:

$ Get-Item tap-windows*.exe|sign\Sign-File.ps1

On the other hand if you’re creating MSM packages do:

$ sign\Prepare-Msm.ps1
$ python buildtap.py -m --sdk=wdk
$ Get-Item tap-windows*.msm|sign\Sign-File.ps1

For additional instructions and background information please refer to
this article on OpenVPN community wiki.

Overriding setting defined in version.m4

It is possible to override one or more of the settings in version.m4 file with
the —versionoverride <file> option. Any settings given in the override file
have precedence over those in version.m4.

This is useful when building several tap-windows6 drivers with different
component ids for example.

Notes on proxies

It is possible to build tap-windows6 without connectivity to the Internet but
any attempt to timestamp the driver will fail. For this reason configure your
outbound proxy server before starting the build. Note that the command prompt
also needs to be restarted to make use of new proxy settings.

MSM packaging

In order to build the MSM packages build and sign the driver first:

• Build the TAP driver with buildtap.py and «-b» flag.
• EV-sign the drivers
• WHQL/Attestation-sign the drivers

Place the signed drivers in a directory structure under tap-windows6
directory. Each platform directory should contain the EV-signed driver with a
«win10» subdirectory containing WHQL/Attestation signed driver for that
platform:

dist
├── amd64
│   ├── win10
│   │   ├── OemVista.inf
│   │   ├── tap0901.cat
│   │   └── tap0901.sys
│   ├── OemVista.inf
│   ├── tap0901.cat
│   └── tap0901.sys
├── arm64
│   ├── win10
│   │   ├── OemVista.inf
│   │   ├── tap0901.cat
│   │   └── tap0901.sys
│   └── (Note: EV-signed driver for arm64 is not used.)
├── include
│   └── tap-windows.h
└── i386
    ├── win10
    │   ├── OemVista.inf
    │   ├── tap0901.cat
    │   └── tap0901.sys
    ├── OemVista.inf
    ├── tap0901.cat
    └── tap0901.sys

Building MSM packages requires Visual Studio 2019 (EWDK is not sufficient) and
the WiX Toolset installed. In a Developer Command Prompt for Visual Studio
2019, run:

$ python buildtap.py -m --sdk=wdk

This will compile the installer.dll file with embedded drivers and package it
as a platform-dependent tap-windows-<version>-<platform>.msm files.

As the WiX Toolset does not support the arm64 platform yet, only amd64 and
i386 MSM files are built.

Optional: Consider EV-signing the MSM packages before deploying them. Thou,
MSM signature is ignored when merging MSM into MSI package, users get a choice
to validate the integrity of the downloaded MSM packages manually.
