MPTCP - Extending Kernel Functionality with eBPF and Netlink

Explore the intricacies of extending kernel functionality for Multipath TCP (MPTCP) using eBPF and Netlink in this informative conference talk from the Linux Plumbers Conference. Delve into the advanced techniques presented by Matthieu Baerts as he demonstrates how to enhance MPTCP capabilities within the Linux kernel. Learn about the integration of eBPF (extended Berkeley Packet Filter) for efficient packet processing and the utilization of Netlink for improved communication between kernel and user space. Gain insights into optimizing network performance, improving protocol flexibility, and addressing challenges in multi-homed and mobile environments. This 32-minute presentation offers valuable knowledge for kernel developers, network engineers, and anyone interested in advancing Linux networking capabilities.
