OK, now everything makes sense!  :-)

So I will not even try with TDI in Vista.

And if you can put back the order information for the TDI samples online, it will be very useful !

Many thanks for the informations.

Regards,

Guilherme

When Microsoft re-wrote the Vista kernel-mode network stack they effectively
eliminated the use of TDI for new NDIS 6 Vista and later network components.

However....

The did include some limited TDI emulation capability. The capability that
they chose to implement is actually intended to support some older NDIS 5
protocols that, frankly, they didn't want to bother porting to NDIS 6. So,
most TDI client software will continue to operate through the new TDI
"stubs" that they built on top of the new NDIS 5 TCP/IP implementation.

They also included some emulation stubs that can allow simple TDI filters to
operate on Vista. Some folks have reported some success using TDI filters on
Vista, but I know that the TDI emulation is NOT perfect and does not support
some features (probably not features that are in any of my samples...) that
may be needed in the kernel.

However, I would not ever suggest writing a TDI filter for Vista and later.
That's just my story, and I'm sticking to it. :-)

=================================
Hello Thomas,

I was interested in this samples because I have some win2k and winXP
deploys, that need some new features.

You said not to use TDI on Vista, theoretically windows Vista still supports
this kind of drivers, why not use? Unpredictable errors?

I will start the project using WFP, but to support the legacy win2k I was
intent to buy this samples that does almost everything that I need, so I can
put support to all windows versions in a small time frame.

I would consider it of course.

However, the WDK has sevral samples already. What sort of samples are missing
that you (or someone...) would b willing to pay for?

In other words: Suggest specific things that are missing. It they make sense, I
may spend some time on them.

(Ok. This is "market research"...)

Hi Thomas,

Hello,

the old "TDI TCP Redirector Filter Driver Sample" has been discontinued, so
which new product can be used to achieve the same result?

There's no way to buy the old ones ?

Guilherme

November 17, 2009 - One user noticed that the initial IPRedir release didn't
support operation on NDISWANIP. Supporting WAN was on my "to-do" list but
didn't quite make it into the initial release.

In addition, there was a bug in the console application chooser that made
the sample applications exit prematurely in some cases.

If you have downloaded the initial IPRedir sample applications and noticed
either of these issues please revisit the download page and fetch IPRedir
V4.00.07.02.

Thanks for your patience.

Current PCASIM NDIS IM Licensees can be provided with the new
NDIS 5 & NDIS 6 samples.

1.) If your PCASIM subscription is current, then you can received the new IP
Redirector samples without additional cost.

2.) If you have licensed the PCASIM samples in the past, then you can
purchase a subscription to the new IP Redirector samples at the renewal
price.

In either case you must contact me and provide your current PCASIM Serial

November 15, 2009 - Finally back from a fairly long stint of consulting.
It's time to be "out with the old and in with the new".

The New - IP Redirector NDIS 5 & NDIS 6 Filter Driver Samples
-------------------------------------------------------------
Today I am releasing the first of a series of new NDIS 5/6 filter driver
samples.

The new series of NDIS filter samples include both NDIS 5 Intermediate (IM)
and NDIS 6 Lightweight (LWF) filters. The drivers are designed to have a
common API so a common Win32 application can operate on platforms ranging
from Windows XP (NDIS 5 driver) through Windows 7 (NDIS 6 driver).

The first of these new samples is the "IP Redirector".

This set of NDIS 5 & NDIS 6 filter drivers redirect incoming and outgoing
IPv4 and ARP packets to a Win32 user-mode application. This allows packet
filtering to be performed in the user-mode environment. Complete Ethernet
packets are represented as ordinary byte arrays and packet I/O is performed
using Win32 ReadFile and WriteFile APIs.

This is a simple and flexible approach can be useful in applications that
are filtering lower-bandwidth connections (Satellite, 4G, DSL speeds), but
is not appropriate on high-performance adapters.

The older NDIS IM-only version of the IP Redirector was fairly popular. This
release extends it to include support for Vista and later platforms.

IP Redirector documentation and downloadable sample executables can be found

The Old - Discontinuing the Advanced TDI and Older NDIS IM Filter Samples
-------------------------------------------------------------------------
These PCAUSA products are being discontinued:

    * Advanced TDI Samples
    * PCASIM NDIS IM Driver Samples

Thanks for your continued interest in PCAUSA products.

The change is a little scary.
 
You need to think like the real TDI client. There are several different ways the client could handle this situation. One is to fill in the IRP that it can return from the call - this is effectively a way to call TDI_RECEIVE_DATAGRAM. Another is to do nothing in the call and sometime later make an explicit call to TDI_RECEIVE_DATAGRAM.
 
To me it looks like BytesIndicated provides a guarantee that BytesIndicated are actually at the tsdu. BytesAvailable specifies the minimum that could be fetched by a call to TDI_RECEIVE_DATAGRAM.

Subject: [discussion-pcausa] Zero IndicatedBytes in ClientEventReceiveDatagram()


When a third party firewall TDI driver is installed, Bytesindicated is zero in the function ClientEventReceiveDatagram(), but BytesAvailable is non-zero. I am able to access tsdu (UDP payload) in the function. As BytesIndicated is zero when ao_recvdg() is called, it returns more_processing_required and byteTaken is zero, and UDP packet is not getting received by app.

 

Just for testing perpose I made following change.

if(BytesIndicated == 0)

BytesIndicated = BytesAvailable

With this change app received UDP packet and everything worked fine.

 

I am wondering if I can make this change safely? Is it possible that BytesIndicated is zero but BytesAvailable is not?

 

When Firewall TDI driver is not present then I never see BytesIndicated is zero.

 

Thanks,

-Ajay
