Windows Packet Filter Kit 3.2.6 released:

• Added special reserved pool for packets handled in kernel mode (these are packets which are not supposed to be redirected to user mode application for further processing: passed/blocked according loaded filters and collected from non-tunneled network interfaces). This feature seriously improves remote debugging capabilities for WinpkFilter based applications. An example, if you debug over RDP and your application load static filters to pass RDP connections prior putting network interface into the tunnel mode then you can safely put breakpoints in the packet processing thread, suspend it, analyze individual packets without a risk to be disconnected.
• Fixed Visual Studio 2015 compiler errors when building WinpkFilter NDIS 6.x Lightweight Filter drivers

Concerning 3.2.7.5 version: ndisrd.sys contents has definitely changed, but unfortunately version in .rsrc is still the same (3.2.7.1):
Can we hope it’ll be corrected?

[Vadim Smirnov]

Yes, NDIS LWF drivers were rebuilt to switch off the debug output, but besides this driver has not changed (and other drivers were not changed at all). If you have any reason to have the resource changed in the onsite build I could consider doing this. However, the onsite build is mostly used for demo and test purposes so I never thought that it can be important.

WinpkFilter 3.2.7.6 update:

• Fixed Hyper-V switch issue: enabling filter driver for virtual switch and at the same time for the network interface below it, could result incorrect send/receive operation counting and thus prevent the filter from correct detach. Under some circumstances it could result DRIVER_POWER_STATE_FAILURE.

Driver version in version resource was also updated according the request above.
