Automatically adjusting process priorities under Linux -

I am trying to write a program that automates based on the configuration file (basically the path - priority added) Sets the process priority.

I thought the best solution would be to have a kernel module that would replace the execve () system call. Too bad, the system call table is not exported in kernel versions> 2.6.0, so actually is not possible to replace system calls without ugly hacks.

I want to do not :

- Replace binaries with shell script, which begin and enter binary - your stock Ubuntu kernel Packet / recompile - Unreadable hacks such as reading the kernel executable memory and estimating the sissell table location - Operating the running processes

I want to be actually : < / P>

- Any type based on the executable path To control the priority of the file, and a configuration file. Rules apply to any user.

Do any of you have any ideas about completing this work?

If you have settled for a polling solution, then the facilities you want to implement Already exist. You can configure a good level of procedures based on process names, users and groups.

It is also possible to dynamically adjust the process preferences based on how many CPU time has been used.
