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 Leonardo Bras 2022-10-27 18:07:28 UTC 
According to Meirav, we need a backport of zero-copy-send to RHEL9.0, since SAP may try to certificate this version of RHEL.
Comment 3 Li Xiaohui 2022-11-08 03:30:02 UTC 
Hi Leonardo,
Can you help confirm if there's a business justification from SAP for the zerocopy support on RHEL 9.0.z?
If not I think we can close this bug since we have already supported zerocopy on RHEL9.2.0
Comment 4 Leonardo Bras 2022-11-08 03:33:21 UTC 
Hello Li Xiaohui,

We are working on that, so we should have a detailed justification soon.
Comment 14 Li Xiaohui 2022-12-05 12:45:51 UTC 
Verify zerocopy feature on kernel-5.14.0-205.el9.x86_64 && qemu-kvm-7.1.0-6.el9.x86_64, test pass:
