FIX: A "Data abort" exception may occur in the RNDIS driver when you access an SMB shared file on a Windows CE 5.0-based device

Consider the following scenario.
  • You run an image that contains the Remote Network Driver Interface Specification (RNDIS) component and the Server Message Block (SMB) component on a Microsoft Windows CE 5.0-based device.
  • You use the SMB protocol to share a file on the device.
  • You connect the device to a Microsoft Windows-based desktop computer by using a USB cable.
  • The device handles the connection by using a USB function controller.
  • You browse the SMB shared file in Windows Explorer on the desktop computer. When you do this, you use the IP address of the device in the range of 169.254.X.Y.

    Note X and Y are numbers between 1 and 254.
In this scenario, you may receive an exception in the debug output that resembles the following exception:
RndisFN:: $$ Halt RX pending: [0] -- TX pending [0] $$
RndisFn:: $$$
RNDIS TX buffer freed.$$$
RndisFn:: Using MAC address: [0-0-bc-31-30-1]
RNDISMINI1 MAC = 02-00-BC-31-30-01.
Data Abort: Thread=8fadd5f8 Proc=8cb39ec0 'device.exe'
AKY=00000005 PC=03fcd0c8(coredll.dll+0x0004d0c8)
RA=02df3fe0(rndisfn.dll+0x00003fe0) BVA=0a4dfe04 FSR=00000005
This problem occurs because a function in the RNDIS driver does not have the permissions to access some buffers in Network Driver Interface Specification (NDIS) packets.
