Hello,
I'm a student at the University of Liege, currently developing a NAT64
(see RFC 6146) module for Netfilter.
In order to develop this module, I had to use some in-kernel function,
such as icmp_send, ip6_output, ip_finish_output, ... and many more.
But many of those functions didn't have an "EXPORT_SYMBOL" allowing them
to be reachable from outside the kernel.
So, to be able to use them, I had to copy paste about 1500 lines of
kernel source code (those functions + related functions). This makes the
module hardly updatable as all those functions are likely to be updated.
Is there a reason why those functions are not associated with an
"EXPORT_SYMBOL"?
Regards,
Pierre Rondou
