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.

The following upstream commit contains a fix to the bpf_fib_lookup() helper which we have backported to RHEL8:
1fe4850b34ab ("bpf: bpf_fib_lookup should not return neigh in NUD_FAILED state")
The commit is missing a Fixes tag, so it will probably not be picked up by our regular searches, so opening this bug to make sure we include it.

Hi Toke,
I want to verify this bug. So, is there a repro procedure for the verification? Or, a sanity test is enough?
BTW, I can't reach you via Slack ? Have an account ?
Thanks!
Jean

I don't think we have a reproducer for the original issue fixed by this commit, so doing a sanity check that it doesn't break anything should be fine :)
