Thanks for replying. I am using racoon for testing. I searched for your
patch in the ipsec-tools, but couldn't find it. It would be helpful if you
could point me to the patch.

The reason I was debugging the kernel is because I was under the
assumption that the kernel should not invoke racoon if a matching SA is
available in the SAD (like in my case).
