I wonder what happens when the Linux TCP stack attempts to open a connection to a remote host when that connection is already open in the RDMA NIC? For that matter what happens if a Linux application decides to listen on a TCP port already listened on by the RDMA NIC? The only saving grace is that they're only doing RDMA rather than arbitrary TCP. However, exactly the same infrastructure can be used to do arbitrary TCP should they wish to. > But we have to realize they've already been given %95 of the > interfaces they need to speak IP using our routes and our neighbour > entries. > > Right? Yes, however I think the same argument could be applied to TOE. With their RDMA NIC, we'll have TCP/SCTP connections that bypass netfilter, tc, IPsec, AF_PACKET/tcpdump and the rest of our stack while at the same time it is using the same IP address as us and deciding what packets we will or won't see.
