Subject: EXPORT_SYMBOL missing in the kernel?
Date: Tue, 24 May 2011 15:03:34 +0200	[thread overview]
Message-ID: <4DDBACA6.2060501@gmail.com> (raw)

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
