I am using some older verion of NetBSD code and landed up into a issue with TCP
connect code when my destination address is Link local address.
On investigation I found that in6_pcblookup_hash() called from
tcp_input() fails and it sent RST back. The reason for failure is that
foreign address of inpcb structure
is not embedded with scope Id and therefore IN6_ARE_ADDR_EQUAL fails as
the local and foreign address passed from ip6_input are embeddedd with scope id
for Link local address.
I am sure this must have been addressed in latest code of NetBSD, which I have
failed to figure out . Can someone help me on this.

I don't have an environment to test the very latest code, but I'm
pretty sure that the problem you described doesn't exist in the
current by code inspection of netinet6/in6_pcb.c, rev 1.94. I also
tried NetBSD 3.1 and didn't see the problem. Could you be more
specific about with which version of the kernel you experienced it?
