UDP server as a kernel module

hi ... i am trying to write an UDP server as a kernel module.
i want to use sys_select(). is it possible to use sys_select in kernel
level.plz help me ......

the actual prblm is

i want to write a server to serve more than 1000 clients
each bound with different port. i created sockets using 'socket'
structure (socket *KSocket ) and bound using KSocket-> ops -> bind ()
(port is different), i want to use sys_select (if possible) function on
these sockets . I heard that creating threads in kernel is not good
idea as using sys_select, so i want to create 4 or 5 threads to serve
all the clients (sockets). can u plz help me to write this.

thanks in advance.

What you need is to create a daemon that can be started at boot. You
can find lots of examples in unix world.
