Unresolved external symbols in <wsk.h> while building


I try to Winsock kernel and write a test project that set up the wsk environment, but the error occured while building project the visual studio can not link the definitions of wsk functions.

I thought there was my fault and some headers are missing on my pc, but I grab the first project on internet that use wsk.h and it's compiled successfully. enter image description here

#include <ntddk.h>
#include <wsk.h>


NTSTATUS registerWSKApp();
NTSTATUS wskAppWorkerRoutine();

NTSTATUS registerWSKApp()
{
    NTSTATUS status;

    WSK_CLIENT_NPI wskClientNpi{};

    wskClientNpi.ClientContext = NULL;
    wskClientNpi.Dispatch = &dispatchTable;
    status = WskRegister(&wskClientNpi, &wskRegistration);

    return status;
}


NTSTATUS wskAppWorkerRoutine()
{
    KdPrint(("[+] Call of wskAppWorkerRoutine!"));

    NTSTATUS status;

    WSK_PROVIDER_NPI wskProviderNpi;

    status = WskCaptureProviderNPI(
        &wskRegistration,
        WSK_NO_WAIT,
        &wskProviderNpi
    );

    if (!NT_SUCCESS(status))
    {
        if (status == STATUS_NOINTERFACE)
        {
            KdPrint(("[-] A requested WSK version is not supported!\n"));
            return status;
        }

        return status;
    }

    KdPrint(("[+] Succesfully capture NPI!\n"));

    //
    // 1. Create socket
    // 2. Bind socket
    // 3. listen socket
    // 4. accept connection
    // 5. receive data
    //

    WSK_APP_SOCKET_CONTEXT socketContext { 0 };
    //creation of socket
    status = createListeningSocket(&wskProviderNpi, &socketContext, NULL);

    if (!NT_SUCCESS(status))
    {
        KdPrint(("[-] Failed to create listening socket!\n"));
    }

    return status;
}   

I try to solve problem in netiodef.h by trying all the compiler settings that are related with this issue, but it isn't help


Solution

  • If your linker reports unresolved symbols in "wsk.h" and sub headers you need to explicitly point the linker to the “netio.lib” library in additional dependencies.

    I think that information should be added in the article "Registering a Winsock Kernel Application" on learn.microsoft.com
