c++ - CcInitializeCacheMap 发生崩溃

问题描述

/*
typedef struct _HRFS_VOLUME_CONTROL_BLOCK
{
    
    FSRTL_ADVANCED_FCB_HEADER VolumeFileHeader;
    ULONG nodeType;
    FAST_MUTEX AdvancedFcbHeaderMutex;
    ....
};
*/
DumpFileObject(*(pVolDev->fileObject));
Vcb = (HRFS_VOLUME_CONTROL_BLOCK_PTR)ExAllocatePool(PagedPool, sizeof(HRFS_VOLUME_CONTROL_BLOCK));

pVolDev->fileObject->SectionObjectPointer = \
    (PSECTION_OBJECT_POINTERS)ExAllocatePool(PagedPool, sizeof(SECTION_OBJECT_POINTERS));;
pVolDev->fileObject->WriteAccess = TRUE;
pVolDev->fileObject->ReadAccess = TRUE;
pVolDev->fileObject->DeleteAccess = TRUE;
pVolDev->fileObject->FsContext = &HrfsData.gVolume;
pVolDev->fileObject->Vpb = Vpb;

CC_FILE_SIZES fileSize;
fileSize.AllocationSize.QuadPart =    fileSize.FileSize.QuadPart = sizeof(PACKED_BOOT_SECTOR);
fileSize.ValidDataLength.QuadPart = 0xFFFFFFFFFFFFFFFF;
            
CcInitializeCacheMap(pVolDev->fileObject,
                &fileSize,
                TRUE,
                &HrfsData.CacheManagerNoOpCallbacks,
                Vcb);

在此代码段中，当我调用 CcInitializeCacheMap 函数时发生了崩溃。

FILE_OBJECT 和转储信息如下：

文件对象大小：d8
文件对象.DeviceObject：c2221670
文件对象.Vpb：c39302e0

我追踪到 nt!CcInitializeCacheMap+0xd3 的地址，发现有一条比较指令。

那么我的程序导致 CcInitializeCacheMap 崩溃的原因是什么？

解决方案

此代码不应设置为 PagedPool Type 。

//ErrorCode:
Vcb = (HRFS_VOLUME_CONTROL_BLOCK_PTR)ExAllocatePool(PagedPool, sizeof(HRFS_VOLUME_CONTROL_BLOCK));
pVolDev->fileObject->SectionObjectPointer = \
    (PSECTION_OBJECT_POINTERS)ExAllocatePool(PagedPool, sizeof(SECTION_OBJECT_POINTERS));;
