Can you be more specific ?

AFAICT, very few information is available on that topic. If you have
specific questions, some people on the list will probably be able to
answer. Otherwise, the sources are the best way to go ...

The daemon interacts w/ the kernel via netlink:

 - for IPsec/MIPv6 policies/states addition/removal/updates (XFRM)
 - for monitoring interface states (UP/DOWN, @ changes, )
 - for interacting with routing tables

It also has some interactions with the kernel using sockets (including
setsockopt(), for which some RFC exist which document the API). It also
plays with /proc to configure/change various aspects of the IPv6 stack. 

Hope that helps,

Cheers
