Re: [ros-dev] Instanciate TAP device for Virtualisation
Cameron, can you take a look at https://jira.reactos.org/browse/CORE-8292 ? This describe the problem occured with the on-the-fly load driver that we need Thanks (Cameron Gutman aicomman...@gmail.com) Tue, 13 May 2014 15:29:47 -0500: InitializeHandler is called when the miniport is started by the PnP Manager. You can't force a miniport driver to be loaded without a device (whether real or virtual) for the miniport driver to control. You'll want to just create an INF file that installs your miniport driver for some PnP ID that you make up. You can then call some SetupAPI functions to create a virtual device node and install your driver on it. Here's an example of what you'll want to do to create the virtual device: https://github.com/CrowdStrike/Tortilla/blob/master/Tortilla/InstallTortillaDriver/InstallTortillaDriver.cppon lines 635-811 And here's an example of the INF you'll need to write: https://github.com/CrowdStrike/Tortilla/blob/master/Tortilla/TortillaAdapter/netTor.inf I don't know whether this will work on ReactOS. The code seems to be there, but that's no guarantee that it works ;) Thanks, Cameron On Tue, May 13, 2014 at 3:15 PM, Maxime Daniel l...@maxux.net wrote: In fact, we the problem we face is the Miniport Initialize function which seems to be ignored when using Virtual Ethernet (without hardware).

[ros-dev] Installing driver without reboot
Hi, Is it possible to install a driver (virtual network interface) witout reboot the system ? I tried TAP interface (installation with devcon: devcon install inf-file tap0901) but the interface is only loaded during the next reboot (same for a ndis sample from DDK) Is there a way to load a driver interface with a true plug'n'play mechanism ? -- Daniel Maxime Linux version 3.6.9-maxux64 (emy) (gcc version 4.7.3 (Gentoo 4.7.3-r1 p1.4, pie-0.5.5) ) #3 SMP PREEMPT Wed Feb 19 16:40:22 CET 2014 16:33:29 up 24 days, 8 min, 1 user, load average: 0.31, 0.68, 0.72 ___ Ros-dev mailing list Ros-dev@reactos.org http://www.reactos.org/mailman/listinfo/ros-dev
[ros-dev] ndis netvmini adapter
Hi, I'm trying to compile and test the netvmini ndis 5 adapter code from WDK, at first to understand how it works, then to modify it for another purpose. At this time I: - put the code on driver/network/dd/netvmini and adapted CMakeLists - put the inf on media/inf and adapted CMakeLists - fixed the code, it builds - add an entry to hivesys.inf to load the driver at boot The driver is well displayed during boot, debug message appears (the DriverEntry), on NtObj, the driver is visible and it appears on Non Plug and Play on device manager. Now, I don't know exactly what to do with it. How can I call the driver and add an adapter ? The userland tool given with the code works (I needed to comment some functions and add _DEV_BROADCAST_HANDLE struct by hand, it seems to not be implemented on dbt.h). When I run the userland tools, it fails with EnumDevices. Some help ? Thanks ___ Ros-dev mailing list Ros-dev@reactos.org http://www.reactos.org/mailman/listinfo/ros-dev
Re: [ros-dev] NDIS NdisIMRegisterLayeredMiniport
Thanks How/when MiniportInitialize is triggered ? I tried with NdisMRegisterMiniport at first, and the driver is loaded (DriverEntry is called and succeed) but MiniportInitialize is not called. Should I specify something ? There is no PnP event. (Cameron Gutman cameron.gut...@reactos.org) Thu, 6 Mar 2014 22:30:49 -0500: There’s no requirement to have any real hardware behind a miniport. You can use NdisMRegisterMiniport and return whatever media type you want in your MiniportInitialize function (most likely NdisMedium802_3 to use Ethernet framing).
