Hi, 'Invalid module' is typically thrown when you don't compile your module against the kernel you are linking into. I think __versions section is added by vermagic.o as part of build process. Please refer http://lwn.net/images/pdf/LDD3/ch02.pdf, Version dependency section for more details. Thanks, Ramesh On Tue, Sep 18, 2012 at 7:10 AM, Pritam Bankar <pritambankar1988@gmail.com> wrote:

Any idea what causes __versions section to get added in *.ko module. A simple hello.ko on ubuntu 12.04 i386 machine gets loaded successfully. Other module just doesn't get loaded giving error " Invalid module ". When I compared both modules with objdump -h I found __versions section was missing from second module and that can be the reason its not getting loaded. How can I add this section to other .ko ? What causes __versions to get added in ko ?
I have compiled both modules with modpost and Module.symvers.
Thanks, Pritam Bankar
