Stable version 1.57 has been released (took lot longer than expected, as Pavel Roskin kept fixing it!). Following is short summary of changes:

* Added support for Linux 2.6.35 - Linux 3.1
* Kernels as old as 2.6.14 are now supported
* IW_AUTH_MFP implemented
* Reserve stack before copying arguments when calling from Windows to Linux
  on x86_64
* Fixed a kernel panic if there are many devices for one driver and one
  fails to initialize
* Fixed a kernel panic with Marvell USB if ndiswrapper is reloaded
* Fixed support for AVM Fritz USB
* Loading drivers with unknown symbols is disallowed, it's a certain crash
* Fixed procfs registration if the network device is renamed
* Added more function stubs
* Build system improved
* Code cleanup, fixed many warnings, style issues and typos

Any way to run 32 bit ndiswrapper on 64-bitLinux system?

Mark _ — 2011-09-15T17:31:48

Hi,I am wondering if there is any way to run a 32 bit ndiswrapper binary on a 64-bit Linux system?  For example could something like ia32-libs be used?  If not, how much effort would be involved to get this to happen, would this require kernel changes, or just changes to ndiswrapper?Thanks,Mark       ------------------------------------------------------------------------------

Instability after ndiswrapper unload with USBdrivers

Pavel Roskin — 2011-08-27T23:44:36

Hello!

I was too optimistic to write in a recent subversion commit that the  
USB problems in ndiswrapper have been fixed.  I managed to unload  
ndiswrapper several times in a row so I concluded that my fix  
(canceling an IRP before freeing it) was the right fix for the problem.

I still think my fix was correct.  Freeing an irp with a cancel  
routine is not a good idea.  But it wasn't relevant to the actual  
problem.  The actual problem happens if IoCancelIrp() is called  
directly from the Windows driver.  It doesn't happen every time.

As far as I can tell, there are three different problems, and it's not  
clear if they are connected.

1) The freed URB is accessed for writing after being freed.  I believe  
that's the real source of instability after ndiswrapper is unloaded.

2) IoCancelIrp() is called with an IRP that has stack location  
pointing the end of the memory allocated for the IRP.  That leads to  
reading dev_obj from random memory.  Fortunately, ndiswrapper's only  
implementation of cancel_routine doesn't use dev_obj at all.  I have a  
proof that IRP is set to that position in
IofCompleteRequest().  I think that function should be reviewed by  
somebody who knows Windows driver programming.  I have a simple fix  
that simply sends NULL instead of dev_obj in IoCancelIrp().  However,  
that fix doesn't fix the instability.

3) I get an occasional "invalid task" from  
NdisMSetInformationComplete(), which is racing against itself.   
However, it doesn't seem to be related to the instability after  
ndiswrapper unload.

As it stands now, the PCI support is pretty good, but USB support is  
quite unstable.  Maybe it doesn't matter for the end users that much,  
as they are unlikely to unload ndiswrapper.  But since we don't have a  
fix, it's hard to say definitely that the instability would only  
happen on the module unload.

I'll appreciate any help with those issues, as they delay the next release.

1.57-rc1

Pavel Roskin has been working to improve ndiswrapper. In fact, all the changes in this release are by him. Following is short summary of changes:

* Added support for Linux 2.6.35 - Linux 3.1
* Kernels as old as 2.6.14 are now supported
* IW_AUTH_MFP implemented
* Reserve stack before copying arguments when calling from Windows to Linux
  on x86_64
* Fixed a kernel panic if there are many devices for one driver and one
  fails to initialize
* Fixed a kernel panic with Marvell USB if ndiswrapper is reloaded
* Fixed support for AVM Fritz USB
* Loading drivers with unknown symbols is disallowed, it's a certain crash
* Fixed procfs registration if the network device is renamed
* Added more function stubs
* Build system improved
* Code cleanup, fixed many warnings, style issues and typos

Please test this version as changes have been all over the place and if something is broken, it helps to know now than later. We expect to release 1.57 soon (couple of weeks at most).

Thanks,

BUG: unable to handle kernel paging request

hymie! — 2011-05-07T11:46:23

Greetings.  I hope I'm doing this correctly.

I have a HP G62-355DX laptop running Linux 2.6.36 from Slackware.

This laptop has PCI Atheros Communications Inc. AR9285 Wireless Network 
Adapter (PCI-Express) (rev 01) network card.  It uses the Linux ath9k
driver, but I'm having problems with it.  Since I've used ndiswrapper
successfully in the past with my old laptop, I thought I'd give it a
try.

I downloaded the SVN trunk for revision 2729.  It compiled and installed
just fine, and the WinXP driver installed as well:

newlaptop-pts/5:/var/log% /usr/sbin/ndiswrapper -l
netathw : driver installed
        device (168C:002B) present (alternate driver: ath9k)

But when I try to modprobe it, I get this error:

May  7 07:11:52 laptop kernel: Disabling lock debugging due to kernel taint
May  7 07:11:52 laptop kernel: ndiswrapper (import:233): unknown symbol: ntoskrn

May  7 07:11:52 laptop kernel: Oops: 0000 [#1] 
May  7 07:11:52 laptop kernel: last sysfs file: /sys/module/led_class/refcnt

(I've got the whole crash report if you want it)

Did I do something wrong?  Is there any help to be had?  Or do I need to
stick with the problematic ath9k driver?

Thank you very much.

ndiswrapper-kmod-common

Gerald Sloan — 2011-03-05T22:11:15

Hello,

I have been wrestling with the installation of akmod-ndiswrapper on my Fedora 14 64 bit machine. No matter what I do I get stopped by this message
 Failed dependencies:
    ndiswrapper-kmod-common >= 1.56 is needed by akmod-ndiswrapper-1.56-1.fc14.1.x86_64
What can I do? All of the repositories I download from show that 

Provides 

  * ndiswrapper = 1.56-1.fc14
  * ndiswrapper(x86-32) = 1.56-1.fc14
  * ndiswrapper-kmod-common = 1.56

The thing I need is in what I am trying to install...it is getting frustrating.

Need another release

Pavel Roskin — 2010-02-01T23:08:54

Hi, Giri!

We need another release.  It turns out that the i386 compilation was
broken since Linux 2.6.31.  The code assumed that Linux 2.6.31 and newer
export cmpxchg8b() on i386, but it wasn't true for any kernel version.

To anticipate future compile errors, I checked compilation with the
current linux-next branch, which includes changes scheduled for the
future kernels.  Everything was fine for i386 and x86_64.

I made a change to satisfy realtime kernels distributed by Ubuntu.  They
don't have init_MUTEX.

There is one big thing that needs to be done.  It's porting the
configuration from Wireless Extension to cfg80211.  Linux 2.6.33 will
disable wireless extensions unless some old wireless driver is enabled
(e.g. ipw2100).  That will surely result in user complaints.  But that
effort is better done in a separate release.

Hi, All,

In the "main page", i see follow line:
-------------------------------------------------------
other devices are known to work: e.g., ethernet cards,
-------------------------------------------------------

I want to know, how many type's of such cards support current time, i
try to find, only find:


  3Com 3C410


      From ndiswrapper

    3COM #3C410, HPNA 2.0 (not wireless)


Ndiswrapper can support normal ethernet card, i mean "not wireless", right?

Thanks for your help first!

Need help to create driver for Netgear WN111v2

Malte Gell — 2009-09-29T01:59:54

Hi there,

I was able to extract the Windows XP driver for the Netgear WN111v2 and WNDA 
300 MBit stick, don't remember the exact name for that stick.

Ok, ndiswrapper -i arusb_xp.inf works, ndiswrapper -l  gives output:

arusb_xp : driver installed
device (0846:9001) present

But, when i load ndiwrapper module into memory und plug in the stick i see 
this in syslog:

Any help appreciated. I could provide you the full Win XP driver package, it 
is around 30 MB, but most files are not needed I gues.

Intel Corporation PRO/Wireless 3945ABG Network Connection [8086:4222] card

krishna.kumar — 2009-08-10T11:34:26

Dear All,

I have a simple problem in doing modprobe of ndiswrapper in case of 
driver of  Intel Corporation PRO/Wireless 3945ABG Network Connection 
[8086:4222] card. The steps which I mentioned is as follows. Please help 
me if I am missing something :


1.
I am using  2.6.19 kernel with 16 kb stack size and smp disable.  I have 
also enabled the wireless option  &  done blacklisting  of  iwl3945  
driver  ( because I  want to test it  with windows driver via  
ndiswrapper.)

3. Till this everything is fine. But when we do modprobe ndiswrapper , 
the dmesg shows following error message.

Can anybody help me, why I am not able to insert the module by modprobe. 
Please help as I am very much tired by this error message.
