How easy is it to extend the XDP/eBPF program with a new input parameter? I see the need for providing the input "source-port" to the eBPF program. E.g. needed when implementing a basic learning bridge (basically a map of <src-mac,src-port>). The concepts of "ports" are not-defined-yet, thus, this change need to be part of a later patchset.
Maybe this "source-port-id" can instead be stored as part of the eBPF program structure? (as it is likely known at registration time) Reminder: XDP patchset I'm referring to is avail here[1]: [1] https://git.kernel.org/cgit/linux/kernel/git/ast/bpf.git/?h=xdp -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat Author of http://www.iptv-analyzer.org LinkedIn: http://www.linkedin.com/in/brouer _______________________________________________ iovisor-dev mailing list iovisor-dev@lists.iovisor.org https://lists.iovisor.org/mailman/listinfo/iovisor-dev
