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

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,
