Container Networking With Netkit: The BPF Programmable Network Device (asg2025)

Introduced in kernel v6.7, the Netkit device is an eBPF-programmable network device designed with containers in mind. In this talk, I will go over the the basics of the Netkit device, and discuss the performance gains we have realized and challenges we faced when rolling out Netkit across millions of containers at Meta.
