The latter is supposed to control the former, including control of attaching to volumes consult InterpretCommand inside mspyUser. We can offer several levels of assistance to meet your specific needs. However, the filter manager will close any client ports when the minifilter driver is unloaded. If the minifilter driver previously opened a kernel-mode communication server port by calling FltCreateCommunicationPort , it must close the port by calling FltCloseCommunicationPort. To me, your question appears to be off topic because it relates to installing an existing piece of software and it isn’t about a problem with code that you’re writing; also, the “code” you included appears to be a configuration file. For more information about using cancel-safe queues, see FltCbdqInitialize. Note that FltCancelFileOpen does not undo any modifications to the file.

The bottom minifilter driver in the stack—that is, the one whose instance has the lowest altitude—receives minospy operation first. When setting the callback data structure’s IoStatus. Email Required, but never shown. FltRegisterFilter has two input parameters. The minispy minifilter comes with an INF file that will install the minifilter. If the minifilter driver has registered a CleanupContext callback routine for a given context type, the filter manager calls the CleanupContext routine before deleting the context.

Preoperation callback routines are similar to the dispatch routines that are used in legacy file system filter drivers. Guessing by where the sample comes from the WDKI’d probably attempt installing via dpinst.
The systtem list includes examples of global cleanup tasks that a minifilter driver might perform: However, the filter manager will close any client ports when the minifilter driver is unloaded.
The minifilter driver is responsible for performing any processing that is needed to undo the operation. I’m trying to get the minispy minifilter from Microsoft to install and function properly.
The following situations are several exceptions to the preceding rule: However, we strongly recommend that a minifilter driver registers this callback routine, because if a minifilter driver does not register a FilterUnloadCallback routine, the driver cannot be unloaded.

This callback routine is also referred to as the minifilter driver’s unload routine. Closing the Communication Server Port If the minifilter driver previously opened a kernel-mode communication server port by calling FltCreateCommunicationPortit must close the port by calling FltCloseCommunicationPort.
DriverEntry has two input parameters. The modified parameters are not received by the current minifilter driver’s postoperation callback routine or by any minifilter drivers above that minifilter driver in the minifilter driver instance stack. If a user-mode application has an open connection to the communication server port, any client port for that connection will remain open after FltCloseCommunicationPort returns.
However, for an IRP-based operation, a minifilter driver’s preoperation callback routine can be called in the context of a system worker thread if a higher filter or minifilter driver pends the operation for processing by the worker thread.
The community isn’t voting to close it here either, and once again that’s for the community to decide and not u. Other unload requests may be failed.

The following list includes examples of global cleanup monifilter that a minifilter driver might perform:. To install the minifilter, do the following: Thanks for trying Caleb, but that doesn’t help and there’s a lot of code involved in this question.
Perform any needed global initialization for the minifilter driver.
Pasted is a copy of my. Registering Preoperation and Postoperation Callback Routines To register preoperation callback routines and postoperation callback routinesa minifilter driver makes a single call to FltRegisterFilter in its DriverEntry routine.
In the MiniSpy sample, the minifilter driver is registered as shown in the following code example:. The topmost minifilter driver in the stack—that is, the one whose instance has the highest altitude—receives the operation first.
Every preoperation callback routine is defined as follows: A minifilter driver’s DriverEntry routine must perform the following steps, in order:
