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.

Comment 2 Jeff Layton 2023-03-22 11:47:20 UTC 
There has been a lot of progress on this upstream. There are now a working prototype NFS client and server patches that use a netlink-based mechanism to hand off TLS negotiation to userland. Hannes Reinecke also has some prototype patches for nvme over tls that use the same upcall. There are still some details to be worked out, but this seems like the way forward so far. We're (tentatively) hoping that some of these patches will make their way into v6.4 upstream, but it's still too early to know. Relevant patch postings so far:

https://lore.kernel.org/kernel-tls-handshake/167726551328.5428.13732817493891677975.stgit@91.116.238.104.host.secureserver.net/T/#t
https://lore.kernel.org/kernel-tls-handshake/167932094748.3131.11264549266195745851.stgit@manet.1015granger.net/T/#t
https://lore.kernel.org/kernel-tls-handshake/c90f39ed-1bcc-7a8f-fd2d-ee4663e94bb4@suse.de/T/#t

There are also NFS client patches, but they haven't been reposted lately. At this point, I'm going to go ahead set the ITR for RHEL9.4. Hopefully by later this summer we should be ready to backport something for this.

Please note that we'll start to use Jira (instead of Bugzilla) to process the RHEL update. Thus this is a candidate to be migrated to Jira.

Comment 5 Jeff Layton 2023-08-09 13:32:45 UTC 
I've started an initial backport of this, based on Chris Leech's backport of the nvmeof work. The current plan is to target 9.4.
Comment 6 Jeff Layton 2023-08-09 13:38:41 UTC 
Draft backport is here. It'll probably need several iterations before it's ready for inclusion:
