File system filter driver linux

 · The Linux kernel architecture does not lend itself to layering and add-on services. There is no concept of filter and miniport drivers. I don't believe that has changed in more recent kernels. It will probably be difficult to impossible for you. –.  · make[1]: Entering directory '/usr/src/linux-headersgeneric' DEPMOD generic make[1]: Leaving directory '/usr/src/linux-headersgeneric' make -C /lib/modules/`uname -r`/build M=/tmp/driver/avflt EXTRA_CFLAGS=-I/tmp/driver/redirfs modules_install make[1]: Entering directory '/usr/src/linux-headersgeneric'.  · Yes, filesystems in Linux can be implemented as kernel modules. But there is also the FUSE (Filesystem in USErspace) interface, which can allow a regular user-space process to act as a filesystem driver. If you're prototyping a new filesystem, implementing it first using the FUSE interface could make the testing and development easier.

There are two ways of programming a Linux device driver: Compile the driver along with the kernel, which is monolithic in Linux. Implement the driver as a kernel module, in which case you won’t need to recompile the kernel. In this tutorial, we’ll develop a driver in the form of a kernel module. A module is a specifically designed object file. Yes, filesystems in Linux can be implemented as kernel modules. But there is also the FUSE (Filesystem in USErspace) interface, which can allow a regular user-space process to act as a filesystem driver. If you're prototyping a new filesystem, implementing it first using the FUSE interface could make the testing and development easier. Windows uses a driver stack model that able to use layers of drivers and therefore it utilizes this mechanism for the concept of filter drivers. The usage of filter drivers is needed for a lot of reasons, some of them related to the need of blocking\monitoring to calls. However, Linux doesn't have this mechanism. Then I have chosen to implement filesystem filter, because in my opinion its the most important one. Based on "UnderStanding The Linux Kernel 3rd Edition" and some kernel browsing.
