Exceptions in BPF

Explore the recent advancements in adding exceptions to the BPF runtime in the Linux kernel through this 28-minute conference talk from the Linux Plumbers Conference. Delve into the necessary modifications made to the BPF subsystem, examining various implementation choices and the rationale behind creating a generic feature. Discover the potential for integrating similar functionalities found in languages like C++ and Rust. Gain insights into the value proposition of exceptions, learning how their judicious and innovative application can streamline BPF program development and enable program behavior guarantees that are challenging to enforce through static analysis in the verifier.
