BPF Struct_ops: Current Status and Latest Developments

Explore the kernel-side feature BPF struct_ops in Linux, which enables user-defined methods to be called by subsystems. Learn about its inner workings, current applications, and latest developments in this 24-minute conference talk from the Linux Plumbers Conference. Discover how struct_ops allows for innovative implementations, such as defining a congestion control algorithm in BPF and registering it with the TCP subsystem for effective traffic regulation. Gain insights into related projects and understand the potential impact of struct_ops on Linux kernel development and performance optimization.
