Hi,
If you try the netlink approach, maybe this link can help (there are
just few changements to do, because of kernel update):

I am currently trying to make broadcast_send (I have some trouble, ie
the other thread), but for unicast_send it works quite good
thank you guys for your prompt replies. I am not able to map the
module name to the kernel src file. I looked in the build and
/lib/modules directories but could not find a direct mapping from the
src to the module file.
Plus the variable i want to change is the one that i have declared in
the sou

"ioctl()" is used to call the kernel function from user space...so i might be
correct one for you...I am not sure

you can try to use IOCTL

You can use sysfs. You can just cat the data in a file in sysfs and set a
variable in your module! The other way is to register a character driver
with open, release, ioctl operations and use ioctl interface to control your
driver.

No heavy data transfer, I just want to set variables dynamically from
the user space. So i think declaring a kernel module parameter and
changing it through the /proc file system should solve the problem.
Also this is the first time I am programming in kernel :) so please
bear with me. Is there an

You can define a kernel module parameter and change it through /proc
filesystem from userspace. Or you can use sysctl. There are lots of
examples in linux kernel.

Hello all,
I need to set some variables defined in a kernel driver from the
user space. Is there a clean simple way to do that? I thought of the
following methods: socket connection, RPC ,etc. but was not able to
find enough documentation regarding the same. Please help me, its
urgent.
Thanks
