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.

Description of problem:
https://github.com/ipxe/ipxe/issues/157
iPXE floods the physical switch with LACP frames, fails to configure network interface.
Version-Release number of selected component (if applicable):
from RHOSP16.2.2
$ sudo podman exec -ti ironic_pxe_tftp rpm -q ipxe-bootimgs
ipxe-bootimgs-20181214-8.git133f4c47.el8.noarch
How reproducible:
I need
- a Dell PowerEdge R830, configured for PXE and UEFI boot
- Mellanox ConnectX-3 cards
- connected to 2 switches with active LACP bonding
Steps to Reproduce:
1. openstack baremetal introspection start <node>
2.
3.
Actual results:
ipxe.efi is properly downloaded, but then the interface fails to configure.
The interface on the switch goes to errdisabled because lacp-rate-limit
tcpdump on the switch reveals the same trace as in the github ticket: switch being flooded with LACP frames.
Expected results:
should work
Additional info:
it works replacing the ipxe.efi from ipxe-bootimgs-20181214-8.git133f4c47.el8.noarch with one I built myself that includes more recent sources + a patch to disable NET_PROTO_LACP

Hi François. As the bug has been fixed in ipxe-20181214-10.git133f4c47.el8, could you check if the problem is fixed using this version?
If it is, please report us any information that could be useful to mark this bug as verified.
Thanks!

Jarod: Could you give François a public link to download the fixed version package and do the testing for the package?

Created attachment 1910398[details]
Unknown_krgfs_crash
used the ipxe-snponly-x86_64.efi to deploy 2 servers:
- 1 unrelated machine: deploys fine
- 1 machine with the ConnectX-3 pro -> crash, log attached.

Hi @frigo .
The crash you specify in this test is something that happened also with previous version or only with this new one?
Comment 28François Rigault
2022-09-26 15:06:47 UTC
hi! no I have never seen this crash before, it is specific to this new version.
Does the package you built yourself (mentioned in the original report description) work on that host where this build failed, or does that fail similarly?
Comment 33François Rigault

the package I built myself works on that host flawlessly yes.
I understand this requires a specific type of hardware to reproduce. I can live with my hacks if fixing it is not trivial.

It sounds like it would require tracking down the specific changes from upstream ipxe that make this work with cx-3 or a full rebase (which we generally frown upon doing at any point in a major release, let alone this late), and without a readily available reproducer and some time and effort (I'm lacking in time), I think we may well have to revert that one patch and revisit this for the next minor release.
