wintun:ERROR_INVALID_PARAMETER on registering ring buffers

Asked 2020-Oct-16 at 07:18

I am currently trying to get the wintun driver to work with my program for simple tunneling (see: https://www.wintun.net/ ).

I successfully find and open the network device, but when it comes to registering the buffer, I get the result ERROR_INVALID_PARAMETER (87). Like I said, opening works just fine and registering is done with SYSTEM privileges (if this is not done, I get ERROR_ACCESS_DENIED (5)).

First attempt was to malloc the ring buffers, but after that did not work I looked at how OpenVPN does it (yes, it added wintun support) and they seem to do with with CreateFileMapping.

First of all, here is my struct:

I can see a difference in your code when registering rings.

QUESTION

Windows: interface without ComponentId?

Asked 2020-Sep-22 at 08:32

Good morning everyone,

For the application I develop, in C++, I need to get the componentId of an interface. In particular, the WireGuard interface (componentId=wintun that is the adapter installed with the official WireGuard installer). Usually I get it from the registry key,

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-0318}\

where the depends on how many interfaces you have, usually is four digits, like 0015 or 0022...

Inside it, there should be the value "ComponentId", in OpenVPN it should be "tap0901", in WireGuard "wintun".

Sometimes I see that I do not have a ComponentId. I have seen it with WireGuard, but the question is more general:

How can we have an interface without ComponentId? when can it happen? If I don't have the componentId, on which value could I rely?

I found the solution here

build 10049 breaks openvpn

Basically, if you need the "ComponentId" key, check also the "MatchingDeviceId"

DeviceIoControl returning ERROR_ACCESS_DENIED

Asked 2020-May-02 at 19:57

I'm trying to interface with a driver for creating TUN interfaces (WinTun), but in order to send and receive data from them I need to register a ring buffer. The code I'm using looks something like this (I omitted the part where I create the device with SetupApi, as that seems to be working):

Found the solution. As @RbMm described, the code that creates the security descriptor only allows access to LocalSystem. That means that it is the only account allowed to talk to the driver.
