Hi, everyone, does anyone know how to implement a filter driver on the Linux platform, such as intercept the read/write operations to the floppy block device. I mean I want to hook all the read/write operations to the floppy block device in my kernel module. Maybe on Windows platform this can be implement by a filter driver. But how can I implement this on Linux platform?
I am so sorry to post this Linux problem on this NT mail list. But I really need your help. Thank you very much.
Michael

Just modify the appropriate source code.

Hi,William, I’ve read that book. But it didn’t mention
how to write a filter driver.
I compiled a module which can hook the
system call a week ago. In that module I hooked the
sys_read and sys_write system call. Then I can get the
read/write operation to the floppy disk. And it works
just fine. But I think it is a high level solution
because my kernel module is located between the Linux
OS and the File System. Now I need a low level
solution or a block level solution. I hope that my
module can be located between the Linux File System
and the floppy block device driver or between the
floppy block device driver and the floppy disk device.
That is a filter driver.
I’ve read some books about Linux kernel and device
driver including Alessandro Rubini’s “Linux device
driver, 2nd Edition”. But no books mentioned the
filter driver.
Another queston, how can I find the floppy block
device’s entry point in Linux?
Thank you very much.
Michael

Ask Linus on this maybe the anwser will be “you does not need it really, as you does not need the kernel debugger”.
