dear hackers,
I am in the process of implementing a routing protocol under 5.0.
This routing protocol is source route based and requires its own header after
the ip header and before any other one such as udp,tcp.
(ip)(new_rt_hdr)(udp)(paylaod)
I am requesting your input as to the best way to approach this. I am thinking
that the quick way would be to open netinet/ip_input.c and for every packet
with ip->ip_p = NEW_RT_TYPE do my processing. I am not using routing tables,
I have another mechanism for routing decisions. and for outgoing packets,
before sending to the appropriate interface, in netinet/ip_output.c insert
the new routing header then pass the packet to ifp->if_output.
My problem is dealing with debuging and portability. With this raw approach I
guess I will have to run builkernel and installkernel all the time. How can I
avoid that? I thought about kernel modules, but I don't know what kind to use
(SYSCALL_MODULE or DEV_MODULE,etc..) and how about netgraph.? does that make
sense?
somebody give a pointer and I'll figure out how to proceed.
I am not that experienced in kernel programming.
Thanks a lot,
Jerry.
