DRIVER_CORRUPTED_EXPOOL bug

我的目的是在Filter中发送自定义数据。可是目前的问题是在每次卸载的时候出现了这样的Bugs:

看起来是Pool的问题，原因是内存访问存在异常，具体原因不详，估计是在创建MDL中可能会出现某些问题。流程：
1. Create an buffer for my data with size of 80

pWriteBuf = (PUCHAR)NdisAllocateMemoryWithTagPriority(pFilter->FilterHandle,BufferSize,FILTER _ALLOC_TAG, LowPoolPriority); NdisZeroMemory(pWriteBuf,BufferSize); // Try to fill this buffer with some necessary data like Ethernet Header pEthHeader = (PTESTPROV_ETH_HEADER)pWriteBuf; 

2.Fulfill the struct of TESTPROV_ETH_HEADER with Source mac address, etc.
3.set the virtual address for MDL
4.Crate an MDL:

pMdl = NdisAllocateMdl(pFilter->FilterHandle, pEthFrameNew, BufferSize); 

5.Copy the data to the MDL

NdisMoveMemory(pEthFrameNew,pEthHeader, BufferSize); 

6.Allocate and initialize a NBL:

pNetBufferList = NdisAllocateNetBufferAndNetBufferList( pFilter->SendNetBufferListPool, sizeof(FILTER_SEND_NETBUFLIST_RSVD), //Request control offset delta 0, // back fill size pMdl, 0, // Data offset BufferSize); 

测试的时候，能用Network Monitor检测出网卡发出的数据：


现在的问题是：为什么会出现这样的蓝屏问题呢？

这是一个痛苦的过程
