The check for length in rawv6_sendmsg() is incorrect.
As len is an unsigned int, (len < 0) will never be TRUE.
I think checking for IPV6_MAXPLEN(65535) is better.

Is it possible to send ipv6 jumbo packets using raw
sockets? If so, we can remove this check.

I don't see why such a limitation against jumbo would exist,
does anyone else?

Thanks for catching this Sridhar.  A good compiler should simply
fail to compile "if (x < 0)" when 'x' is an unsigned type, don't
you think :-)
