I have one doubt that, I am not writing my classifier as kernel module, I am directly modifying existing code for this. Can I still make use of 'ioctl' calls ? I am little new to this kind of use of ioctl calls, Can I get some examples, tutorials or existing systems where 'ioctl' is been used for this kind of interaction? Is it possible to use "/proc" filesystem over here, to so that in "step 4)" in above method the program 'prog1' will read the rules from file and then write them into some file in /proc which will allow my kernel code to get access to that data ?
If you have well structured data, then sysfs (/sys) would be a better choice. sysfs is designed to only have one data value per file, so if you have a dozen parameters you want to pass, then you would create a dozen files in the sysfs structure.
