Hello All I am wirting kernel module and I want to call some ipv6 stack function from it (like ip6_forward). I am including proper header files so compiler detects that functions, compiles module, but at the end it returns warning like that: WARNING: "ip6_forward" [/path/to/my/module.ko] undefined! Resulting module cannot be inserted as I get following output: insmod: error inserting 'module.ko': -1 Unknown symbol in module I guess that this issue takes place because corresponding macro EXPORT_SYMBOL(ip6_forward) is not defined in kernel source. But it seems strange to me that such a fundamental functions cannot be used by module writers. What is more, I found on net some exemplary module source and I found ip6_forward function called from it. I defined "GPL" as license of my module and I try to compile it under 3.0.4 kernel version.
