WFP驱动程序BSOD位于FwpsInjectTransportReceiveAsync0 [英] WFP driver BSOD at FwpsInjectTransportReceiveAsync0
问题描述
嗨
我们有一个基于检查WDK样本的WFP驱动程序。
在堆栈中我们可以看到mydriver！WFPCloneReinjectInbound + 0x18c我正在调用FwpsInjectTransportReceiveAsync0函数。
BAD_POOL_CALLER（c2）
当前线程正在发出错误的池请求。 通常这是一个错误的IRQL级别或双重释放相同的分配等。
参数：
Arg1：0000000000000007，尝试释放已释放的池
Arg2：0000000000001200，（保留）
Arg3：0000000000000000，池块的内存内容
Arg4：ffffe00005c8e168，池块的地址被解除分配

有些观察结果可能有所帮助：
- >有时当我们将数据包挂在ALE AUTH RECIEVE（INBOUND）然后在单独的线程中处理数据包然后重新注入它时会对NET_BUFFER_LIST进行处理。
因为这种情况有时只会发生，所以当我们试图推迟BSOD时.B
- >该机器安装了NSClient ++。据观察，当nscp.exe在端口5666连接时，在服务器进程中它是5666端口的INBOUND，并且在重新注入数据包的同时 dereferences.A卸载NSClient ++
后，这个问题也很少发生。
- >我想知道在什么条件下发生了derefernce，以便我可以在以后针对该特定情况自行省略解除引用。
- >通过谷歌搜索我可以找到很多这样的情况，其中WFP驱动程序崩溃类似，但解决方案只是卸载特定的驱动程序。

Hi
We have a WFP driver based on inspect WDK sample.
As in stack we can see mydriver!WFPCloneReinjectInbound+0x18c I am making an call to FwpsInjectTransportReceiveAsync0 function.
BAD_POOL_CALLER (c2)
The current thread is making a bad pool request. Typically this is at a bad IRQL level or double freeing the same allocation, etc.
Arguments:
Arg1: 0000000000000007, Attempt to free pool which was already freed
Arg2: 0000000000001200, (reserved)
Arg3: 0000000000000000, Memory contents of the pool block
Arg4: ffffe00005c8e168, Address of the block of pool being deallocated

There are some observations which may help:
-> Happens sometimes when we pend packet at ALE AUTH RECIEVE ( INBOUND ) and then process packets in separate thread and then while reinjecting it deferences the NET_BUFFER_LIST.
Since this happens only sometimes,so when we try to deference BSOD happens.
-> The machine has NSClient++ installed.It is observed that when nscp.exe connects at port 5666 then at server process it is INBOUND at 5666 port and while reinjecting the packet it dereferences.After uninstalling NSClient++
this problem also happened though very infrequently.
-> I want to know under what conditions does derefernce happens so that I can skip dereference myself later for that particular case.
-> Searching through google I could find many such cases where WFP driver crashes similarly but everywhere the solution is just to uninstall the particular driver.

推荐答案
你好，
据我记得你应该在分类回调中引用原来的NBL，
As far as I recall you should reference the original NBL in the classify callback,
然后，您需要克隆原始NBL并注入CLONE并取消引用
then, you need to clone the original NBL and inject the CLONE and dereference
原始NBL。
你这样做了吗？
