We dive into the Linux kernel this week with guest Leonardo Di Donato, Open Source engineer at Sysdig. Leonardo works full-time on the Falco project, a runtime security engine that listens to the Linux kernel using eBPF - the extended Berkeley Packet Filter. Leonardo tells the hosts about the architecture of eBPF, how he has used it before and now, and what’s coming up for Falco.
