communication between user space and kernel module
 

hi
I have two code of user.c and kernel.c , i have compiled new kernel in my system , but i don't know how to compile these code.
may i use any IDE or GCC.

Communication between userspace and kernel is via syscalls and ioctls.

If you want to compile kernel module then read kernel-module programming howto from TLDP.

Also read LDD (Linux device driver programming) book. Latest you have to pay. But old (a version before) version is available for free from web.

but i want to establish connection via netlink socket between user space and kernel space then i want to compile , but i don't know how will i compile my codes.. ?

Read this page on netlink.
