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 J. Bruce Fields 2019-12-13 21:44:00 UTC 
The NFS protocol doesn't allow COPY to and from the same file, but the copy_file_range() system call does allow that.  We need to return a reasonable error in that case.  Upstream NFS is returning EOPNOTSUPP, so the vfs falls back to splice.  In RHEL7 that fallback is being removed to fix bug 1736794, so we need to return ENOSYS.

Comment 14 Marko Bevc 2020-06-24 16:19:51 UTC 
Thanks, since 3.10.0-1127.13.1.el7 is repos, do we have an ETA or repo which we can try patched kernel-3.10.0-1148.el7 from? Thanks!
Comment 15 Marko Bevc 2020-06-30 17:34:27 UTC 
Does anyone have any feedback on progress on this one? Thanks!
Comment 16 Christian Horn 2020-07-01 01:29:49 UTC 
Marko, the proper errata meant for production systems 
should become available with the release of RHEL7.9GA.
Comment 17 Marko Bevc 2020-07-01 12:20:04 UTC 
Do you have information if this is going to make it to CentOS Streams before next minor release? Trying to explore options to avoid 6 months wait time as it's blocking upgrading now. Thanks!
Comment 18 Christian Horn 2020-07-02 05:08:23 UTC 
Customers with RHEL subscription and access to the rhel-7-server-htb-rpms 
channel (not sure what needs to be full filled to get that) should have 
access to kernel-3.10.0-1149.el7 and kernel-3.10.0-1152.el7 which would
also include the patch (but we would not recommend these for production 
systems).

Sorry, unsure about the centos stream release policy.  While Fedora bug-
zilla is nicely integrated with RHEL bugzilla, it's hard for me to 
identify which efforts are underway for centos stream.

Indeed, normal Centos minor releases are typically weeks after the 
upstream/rhel release.
Comment 20 Marko Bevc 2020-09-29 12:23:51 UTC 
Nice, any news on when GA date is scheduled for?
