ip_wccp.c for WCCP v2 question

Hi folks,

We've got WCCP v2 working with Squid, thanks to some fast coding by
Kevin Wormington.

Would someone (hopefully with more Linux kernel hacking knowledge than
I) take a look at this ip_wccp.c module:

http://www.swelltech.com/pengies/joe/patches/ip_wccp.c

It's only a couple of lines bigger than the original ip_wccp.c for v1 of
WCCP, where it checks for the extra 4 octets of the v2 GRE header and
then skips them for the decapsulation...but something is causing an oops
on our test box. We're not real sure exactly what is going on, but this
seems as likely a candidate as any, since the box doesn't crash until it
starts seeing WCCP traffic. Unfortunately...because Kevin's router only
has WCCP v2 and my router only has v1, we can't do any cross-testing.
And the Squid in testing has not yet been made both v2 and v1 aware (it
can currently do v2 just fine...but v1 is broken, I'll be fixing that
over the next few days).

I'd welcome some comments from you guys, if you see anything problematic
in the module...
