Description
The eXpress Data Path (XDP) is a "hook" in the Linux kernel providing programmability at the lowest layer of the Network Stack (at the device driver layer) and can even be hardware offloaded to programmable devices (e.g. SmartNICs). XDP provides an easy way to perform some parts of DNS handling in the kernel but still have traditional userspace software 'after' that. XDP does not have to replace DNS software in userspace, it can augment it.
With this presentation you will experience how DNS can benefit from XDP with hands-on examples of directly usable running code. We will show how operators can use XDP programs to deal with Denial of Service attacks and otherwise tweak their DNS service behaviour.
