RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

.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.
