'tainting kernel' problem in linux-2.4.18

'tainting kernel' problem in linux-2.4.18

[Pawan Deepika]

Hi,

 I am trying LKM with linux-2.4.18. I have a problem
here. When I load the module using 'insmod' command,
module gets loaded but I get following error

------------------------------------------------------
/sbin/insmod ./hello.o
Warning: loading ./hello.o will taint the kernel: no
license
  See http://www.tux.org/lkml/#export-tainted for
information about tainted modules
Module hello loaded, with warnings
----------------------------------------------------

Can anyone tell me why I am getting this problem and
what is the impact of this error while module is
running in kernel. 

Thanks in advance.

Regards,
Deepika

Read the url provided in the error message.

If that is not enough, perhaps this one will help: 
http://lwn.net/2001/0906/kernel.php3

You may want to try kernel-newbies instead since this would be more 
on-topic there.

HTH,

The module police now require you to put something like:
MODULE_LICENSE("Spellman Empire") (or something like that)
in your module.

Why is the government concerned about the lunatic fringe? Think about it.

Thanks a lot.

 Putting MODULE_LICENSE solved my problem.
