Why can’t?
Even in SDK there is an example who to query ‘tcp’ device created by
‘tcpip.sys’ from user mode using DeviceIoControl
And by the way where I can find info about ways of communication between
user mode and kernel mode,
So far I’ve heard of
Sergo.
Hi Sergo,
The LPC is document in the :

Hi, Yatindra
I have the book. It mentions them but doesn’t say how to use them.
Do you have any info about ‘tcpip.sys’?

Just IOCTL description and format of input buffers for devices

This question comes up over and over on this list. You can’t do it
directly from user-mode. Read up on the TDI section of the DDK. All of
the structures, I/O control codes, and semantics are described there.

From user mode? This will give you no advantages.
Just use WinSock, but to it smartly.

Hi Sergo,
Use the TDI Filter driver, and you will get all the details of the IOCTLS what tcpip.sys will give you.

Watching a pirated movie? Stop now! Say no to piracy!
In fact, I can.
There is even an example in SDK.
see
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/devnotes/winprog/tcp_request_query_information_ex.asp
The problem SDK doesn’t publish codes for sending/receiving something, (like
it does for hard drives, CD, LPT).

Sergo,
That ioctl is NOT talking to any of the protocols TCP, UDP etc, it is an
interface to the stack MIB, it’s the ioctl that tools such as ARP and ROUTE
use to read and configure the stack. The ioctl has always been there,
though I have to say that this is the first time that I’ve seen the details
documented. I had to reverse engineer them about 8 years ago.
As an ioctl this is NOT doing what you keep deceiving yourself into
believing it might be doing. Please listen to the people here and
elsewhere, they have been telling you the truth, you can NOT use ioctls to
control the TCP stack from user-mode.
Why do you want to ? The mainline code path in the Winsock DLLs often
takes less than 50 instructions to switch to kernel-mode. I can’t speak
for AFD.SYS, but I understand that the main I/O code path there is also
very efficient.
The reason the SDK does not publish ioctls for sending and receiving on a
transport stack is because there aren’t any. What the SDK does publish as
the interface to transport stacks is Windows Sockets 2 calls and some
Microsoft extensions.
regards,
Mark.

Querying information from an existing handle is one thing. Advancing
TDI state is quite another. (e.g. bind, send, receive, etc.) Look up
IRP_MJ_INTERNAL_DEVICE_CONTROL in the TDI specs. TDI protocols are
expected to provide most of their semantics through
IRP_MJ_INTERNAL_DEVICE_CONTROL. They are expected to expose a SUBSET
through IRP_MJ_DEVICE_CONTROL – the subset that is safely accessible
through user-mode applications.
