Developers are working on enabling BPF programs to send network packets directly, eliminating the dependency on user-space agents for data forwarding. This improvement aims to enhance the resilience of security monitoring tools like Tetragon by preventing single points of failure where killing the user-space process disables reporting.
Background
BPF (Berkeley Packet Filter) is a powerful Linux kernel technology used for tracing and networking, but currently often requires user-space assistance for complex tasks like remote logging. This development seeks to extend BPF capabilities to handle packet transmission natively within the kernel context.
