need help compiling this module meant for 2.6.9 kernel

hedpe · 02-16-2006, 10:09 PM

Hey guys,

I am trying to compile some code that compiles fine on the kernel it was intended for, 2.6.9 ... well I am running 2.6.15-r1 now and it seems some kernel IP implementation has changed.

Here is the error/warning:

Code:

*** Warning: "tcp_protocol" [/home/hedpe/temp/host_driver.ko] undefined!

Which comes from the line:

Code:

extern struct net_protocol tcp_protocol;  /* The TCP protocol already defined */

Well, i suppose its no longer already defined

On another note, he was using the structures tcp_opt and inet_opt which I believe were replaced by tcp_sock and inet_sock

I can't seem however to find out what replaced tcp_protocol so I can update this code.

Thanks!
George

you know what thought, i found this still in my 2.6.15-r1 kernel:

/usr/src/linux/net/ipv4/af_inet.c

Code:

static struct net_protocol tcp_protocol = {
  .handler =  tcp_v4_rcv,
  .err_handler =  tcp_v4_err,
  .no_policy =  1,
};

so why is it giving me that error?

That is ipv4 code... and since i'm talking on this very forum, I am assuming ipv4 is working :P

when I try to load the module, dmesg also spits out at me:

Code:

host_driver: Unknown symbol tcp_protocol

here are some of my kernel settings:
