问题 According to the definition, A file system filter driver is an optional driver that adds value to or modifies the behavior of a file system. A file system filter driver can filter I/O operations for one or more file systems or file system volumes. Depending on the nature of the driver, filter can mean log, observe, modify, or even prevent. I want to write a filter driver for Linux which will intercept all read requests to an ext4 partition and redirect a few of them based on some application

问题 I am using pFileObject->FileName to get the name of file opened in a kernel mode filter driver.This file name returned by this is in the form of UNICODE_STRING . I want to convert it into std String . What is the method ??? Please do provide example if possible... Below is the code NTSTATUS FsFilterDispatchCreate( __in PDEVICE_OBJECT DeviceObject, __in PIRP Irp ) { PFILE_OBJECT pFileObject = IoGetCurrentIrpStackLocation(Irp)->FileObject; DbgPrint("%wZ\n", &pFileObject->FileName); return

Are filter drivers intended to extend system drivers?

问题 Are filter drivers intended to extend system drivers? Is this their main purpose? Are they basically just an extra layer that sits between the driver and the user? This seems overly simple an explanation and I am wondering if I am missing something. Are there good ways to learn more? 回答1: In a way yes. For example, if file system filter driver is for file encryption/compression/security, it is enhancing the file system functionality. The filter driver does not handle talking to actual devices

How to push and pull from github without sharing sensitive information? Smudge & clean?

问题 When I pull from github to a server repository I want to avoid overwriting localized sensitive information in certain files, for example config.php. Note: it's not an open-source type repo; I have full control over the repository, I'm the only user, it's private, but critically, it's based on an open-source framework that might change the structure of the config files . I just want to be able to pull from it to test, staging, and production and not accidentally have production's config end up

libusb-win32: Automated installation of a driver filter

问题 I've faced a problem getting my libusb-w32 based program to detect devices. The program has to detect digital cameras, and I need to automatically install driver filter for any new camera to be detected without any manual work. I've used install-filter i --class={6BDD1FC6-810F-11D0-BEC7-08002BE2092F} , i. e. installing filter for MTP devices, and it seemed to work. But today I tried it on a clean machine and found out it actually only seemed that way. Tried install-filter with different

They rely on lower level drivers to communicate with device. The filter drivers are add-on to the drivers
