Will the Splunk System Driver be rebuilt with a non-obsolete DDK


On Windows 2008 R2 x64 the SPLUNK Trace Kernel Mode Driver (splunkdrv-win6.sys - v6.0.6000.16386) shipped with Splunk Universal Forwarder 4.2.3 (build 105575) is listed as being built with the Windows Codename Longhorn DDK!!

Now this DDK was not meant for production driver builds and contained some major issues (which of course may not affect this driver), however when Microsoft released the supportd DDK all vendors are supposed to rebuild their drivers using this.

My question is did SPLUNK rebuild the Kernel Mode Driver with a production DDK, and if so which build of SPLUNK does it ship in and if not will you do a rebuild of this driver with a supported DDK?

I know this is an old thread but the issue seems to be back I am seeing an unsigned driver Splunk Network Kernel Mode Driver Windows Win 7 DDK provider. This is on Windows Server 2016 with secure boot enabled, (who wants and insecure boot for security software).

This has been fixed in version 5 for Windows 7.


If this hasn't been fixed as of Splunk 4.3.2 (which is the current), I would recommend a support case regarding this.
