.eBPF for *tc* is now fully supported The Traffic Control (tc) kernel subsystem and the *tc* tool can attach extended Berkeley Packet Filtering (eBPF) programs as packet classifiers and actions for both ingress and egress queueing disciplines. This enables programmable packet processing inside the kernel network data path. eBPF for *tc*, previously available as a technology preview, is now fully supported in RHEL 8.2.

Description Jiri Benc 2019-09-25 09:59:44 UTC 
cls_bpf and act_bpf are part of the tc subsystem in the Linux kernel. They allow both cBPF and eBPF programs to be used as a way to classify network packets and execute actions on them.

The eBPF part has been Tech Preview in RHEL 8.0 and 8.1. The RHEL 8.0 release notes state:

------
eBPF for tc available as a Technology Preview

As a Technology Preview, the Traffic Control (tc) kernel subsystem and the tc tool can attach extended Berkeley Packet Filtering (eBPF) programs as packet classifiers and actions for both ingress and egress queueing disciplines. This enables programmable packet processing inside the kernel network data path.

(BZ#1699825) 
------

With RHEL 8.2, this will leave the Tech Preview state and will be fully supported.
