可能导致“MDL在同一进程列表中插入两次”的原因是什么?

我们正在开发NDIS协议和微型端口驱动程序。当驱动程序正在使用且系统处于休眠状态时,我们会收到错误检查(蓝屏),并显示以下错误:

LOCKED_PAGES_TRACKER_CORRUPTION (d9)
Arguments:
Arg1: 00000001, The MDL is being inserted twice on the same process list.
Arg2: 875da420, Address of internal lock tracking structure.
Arg3: 87785728, Address of memory descriptor list.
Arg4: 00000013, Number of pages locked for the current process.

堆栈跟踪不是特别有用,因为我们的驱动程序没有出现在列表中:

nt!RtlpBreakWithStatusInstruction
nt!KiBugCheckDebugBreak+0x19
nt!KeBugCheck2+0x574
nt!KeBugCheckEx+0x1b
nt!MiAddMdlTracker+0xd8
nt!MmProbeAndLockPages+0x629
nt!NtWriteFile+0x55c
nt!KiFastCallEntry+0xfc
ntdll!KiFastSystemCallRet
ntdll!ZwWriteFile+0xc
kernel32!WriteFile+0xa9

哪些类型的问题可能导致此MDL错误?

1 个答案:

答案 0 :(得分:1)

事实证明问题与我们的IRP_MJ_WRITE处理程序中的此代码有关:

/* If not in D0 state, don't attempt transmits */
if (ndisProtocolOpenContext && 
    ndisProtocolOpenContext->powerState > NetDeviceStateD0)
{
   DEBUG_PRINT(("NPD: system in sleep mode, so no TX\n"));
   return STATUS_UNSUCCESSFUL;
}

这意味着我们没有完全完成IRP,因此NDIS可能会做一些有趣的事情。添加对IoCompleteRequest的调用解决了这个问题。

/* If not in D0 state, don't attempt transmits */
if (ndisProtocolOpenContext && 
    ndisProtocolOpenContext->powerState > NetDeviceStateD0)
{
   DEBUG_PRINT(("NPD: system in sleep mode, so no TX\n"));
   pIrp->IoStatus.Status = STATUS_UNSUCCESSFUL;
   IoCompleteRequest(pIrp, IO_NO_INCREMENT);
   return STATUS_UNSUCCESSFUL;
}
