PREROUTING IPVS bypass conntrack (con.) • Egress • Original way • Nf local-out -> ip_output nf post-route -> ip_finish_output • The new way • Call ip_finish_output directly Pre-route Conntrack Pre-route Linux distributions • Build IPVS kernel modules in Ubuntu, Centos • IPVS-eBPF next generation on the way • Implement IPVS SNAT with eBPF without modification to kernel. Thanks! • Learn more about TKE

derived from the algorithms • Efficient interoperability with coroutines • An open and extensible way to specify where, how, and when work should happen … including some standard ones: an event loop, anymore.

learn by doing • You don't need to master Rust; learning Rust by hacking Rust compiler is a great way • Treat it as a game, have fun, remain patient • Ask for help on Zulip if needed Want to have a

for (var i=0;i<100000;i++) { doSomething( () => { val++; } ); } } Loops • Proper way function loops() { var val = 0, fun = function() { val++; }; for (var i=0;i<100000;i++)
