Lately I've been working on adding FIB awareness to bind(2) and inpcb lookup.
Below I'll describe the project a bit. Any feedback/comments/suggestions would
be appreciated.
Today, a TCP or UDP socket can receive connections or datagrams from any FIB.
SCTP?
Any thoughts/comments?
How much use are FIBs still these days? Half of the original use cases
I can think of could easily and better be overcome by using vnet jails
with a physical or virtual interface (e.g, vcc) being delegated to the
vnet.
I wonder if anyone on FreeBSD is using FIBs to actually have multi-FIB
forwardig but that very little touches your use case apart from the mgmt
which again can be factored out better (or inversely, factoring out the
forwarding).
I would honestly know who and how FIBs are still in use today or if they
should be put on a list to be removed for 16 (I assume I might be
surprised).
That all said with your opt-in approach if the code itself doesn't bring
too many new complications I'd be happy with it (assuming FIBs still
have a use case).
