Hi,
status update here.
I implemented successful basic 6CO RA messages at sending and
processing inside radvd.
There might also the question if processing 6CO inside kernel or
userspace? I put the basic functionality inside userspace for now.
How are you feeding the entries your receive back into the kernel? The
debugfs interface right now?
If we want to go with userspace handling for 6CO we need something
better at some point.
I will send patches for this in the next days.
Great.
Anyway I figured some things out which was completely wrong inside this
patch.
- There exist one context based table only.
In rfc6282 stands:
The specification enables a node to use up to 16 contexts. The
context used to encode the source address does not have to be the
same as the context used to encode the destination address.
and I thought it was $SOME_TABLE[DCI] != $DIFFERENT_TABLE[SCI].
But it means in general simple that it can be: DCI != SCI.
With this knowledge the code gets much smaller.
Interesting point. I also overlooked this during the first review rounds.

Stefan Schmidt
