Requiresmingw-w64-dpp and Windows 10. Windows 11 may or may not work, not tested yet.

Did you ever ask yourself the question: how-the-hell can I open a socket in kernel mode with a Mingw-w64 compiled driver?Well, this is the solution.mingw-w64-ksocket simplifies the use of stream/datagram client/server sockets.The API is similiar to the BSD socket API.Greetings toKSOCKET for this sweet approach.

Compatible with C and C++ drivers.

Build it:

make DPP_ROOT="[path-to-mingw-w64-dpp-template-dir]" all

To install & (self-)sign the driver:

make DPP_ROOT="[path-to-mingw-w64-dpp-template-dir]" DESTDIR="[path-to-install-dir]" install

The directory[path-to-install-dir] should now contain three new files:

• driver.bat /driver-protobuf-c.bat /driver-protobuf-c-tcp.bat: setup the driver service, start it, stop it when it's done and delete it
• driver.sys: example driver that uses kernel sockets (used together withuserspace_client.exe)
• userspace_client.exe: example userspace application which communicates with the driver via TCP
• driver-protobuf-c.sys: example driver that make use of protobuf-c (local, no TCP/IP)
• driver-protobuf-c-tcp.sys: example driver that make use of protobuf-c via TCP/IP (used together withuserspace_client_protobuf.exe)
• userspace_client_protobuf.exe: example userspace application which leverages protocol buffers to communicate with the driver via TCP

Start*.bat asAdministrator.

If everything works fine, there should be a text displayed inuserspace_client.exe /userspace_client_protobuf.exe console window, received from the driver.

For more debug output, it is recommended to use a debugger or log viewer likedbgview.
