Summary:
Fixed the hipconf add map problem.
Revision:
hipl--beet--2.6--patch-57
I think the XFRM synchronization is not needed when calling "hipconf add
map". On the userspace branch, the synchronization did not result any
SA, but rather updated the kernel copy of the hadb. The same applied for
the rest of the hip_xfrm_update calls, so I removed them. hip_xfrm_add
was not referenced either so I removed it too.
Next problem: global SP is not created properly when hipd is started
even though hip_setup_sp_prefix_pair() is called from main(). I
discovered this by:
tools/hipconf add hi default
tools/hipconf add map <HIT> <IPv6>
nc6 <HIT> 12345
So, (rougly) all of the tasks are the following in cronological order:
* Fix global SP HIT prefix setting in hip_setup_sp_prefix_pair()
* Triggering of base exchange
* I have already registered the daemon to listen for XFRM_NETLINK
messages in hipd.c:main()
* Implement XFRMGRP_ACQUIRE in netdev.c:hip_netdev_event()
* Sending of HIP packets
* See preoutput.c:hip_csum_send()
* You may want to borrow some functions from the Boeing HIP code for
handling the IP header
* Receiving of HIP packets
* See hipd.c:main() FD_ISSET(hip_raw_sock, &read_fdset)
* You may want to borrow some functions from the Boeing HIP code for
handling the IP header
* See that SA creation works properly during base exchange
* Note that we have to create now a "local" SP for each HIT pair,
i.e., the global SP HIT prefix is not enough due to the BEET design
* See that SA creation works properly for handovers
