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.

Fixed In Version: xdp-tools-1.4.0-1.el9
Doc Type: Enhancement
Doc Text:
.The `xdp-tools` package rebased to version 1.4.0 The `xdp-tools` package has been upgraded to version 1.4.0, which provides multiple bug fixes and enhancements. Notable changes include: * The `xdp-bench` utility gained support for multi-buffer eXpress Data Path (XDP) and for benchmarking the `xdp_load_bytes()` helper in the kernel. This feature enables conducting network benchmarking tests with large maximum transmission units (MTUs). * The locking of the command line utilities of `xdp-tools` was improved to prevent stale locks if the utility did not exit cleanly. * The `libxdp` library contains a new `pass:[xsk_umem__create_with_fd()]` API that accepts an extra file descriptor of an already open `AF_XDP` socket. You can use this function as a substitute for the regular `pass:[xsk_umem__create()]` function when a process does not have `CAP_NET_RAW` privileges.

Hi Toke,
Please advise!

Comment 14 Toke Høiland-Jørgensen 2023-08-07 14:19:50 UTC 
The tcp-trafficgen utility only supports IPv6. It looks like you ran the UDP test over IPv6, any reason you can't do the same for the TCP test? :)

Also, nice work getting everything tested while I was away!

I see.
NOTE: I have passed the project to Rick.

Was trying to get some bugs done before heading for a new adventure.
It's been great working with you.

Right, gotcha! Rick, let me know if you need anything more from my side!

Comment 20 Toke Høiland-Jørgensen 2023-09-21 13:42:23 UTC 
Sure, added some text; hoping you can work from that :)
Comment 22 Toke Høiland-Jørgensen 2023-09-21 16:00:06 UTC 
No, your version is definitely better, thanks! Just fixed a few wording nits, otherwise LGTM :)

BTW, we also separately added a known issue for xdp-tools, see https://issues.redhat.com/browse/RHEL-3382 - not sure if those need to be cross-referenced somehow? I left the 'features' command out of the doc text here since it's broken as per that other issue...

I think that known issue should be documented just as a separate release note. Since it is a known issue i would not mention it in this rebase. Typically, the docs team tends to mention in the rebases just new features and bugfixes.

Alright, SGTM; thanks!
