Hi everyone,
We're currently developing a new communication using custom layer 2 and 3
that we'll be using in a cubesat and I'm looking on how to create the layer
3 driver for linux (similar to af_inet.c but the headers are completely
different). I've read something similar in a thread about a previously
asked question here, but it didn't really answer my questions. And so, my
questions are:
1. Will it suffice to patch linux/socket.h and insert the PF_xxxx before
PF_MAX then use the added PF_xxxx as family in struct net_proto_family?
2. Is there another way to do the above without patching and only in an
out-of-tree module?
3. How do I expose the new AF_xxxx to userspace? It seems like macros for
AF_xxxx are placed in bits/socket.h, but I haven't found a way to patch it.
Thanks,
Cedric
