Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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:
GNOME 41+ blocks external applications from accessing private GNOME D-Bus APIs that applications have previously (ab)used. These APIs are not yet blocked in GNOME Shell in RHEL 9 and should be, otherwise it is entirely possible that downstream patches will be required in future GNOME Shell upgrades to allow access to them when upstream forbids them.
Version-Release number of selected component (if applicable):
40.8-3.el9
Additional info:
Here's the upstream MR for restricting them: https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1970

I don't see how that is the case. We won't rebase the desktop in RHEL 9, and we don't make any API promises for gnome-shell across major RHEL versions.

Even if you don't rebase the desktop, these APIs should be blocked so users don't use them.

because?
I don't think we can backport the restriction to RHEL 7 and 8, because while nothing outside core GNOME components is meant to use those APIs, we would risk breaking callers that do anyway.
And if it's allowed in RHEL 8, I don't see why the restriction cannot wait until RHEL 10.

I'm not asking to backport the restriction to RHEL 7 and 8, just RHEL 9.
I know of applications that I don't want to comment on publicly that will not be motivated to migrate to the xdg portal APIs if the GNOME ones are not blocked. They're already blocked in Fedora, but blocking them in RHEL will ensure that they care enough to fix things properly.
I had mentioned this in the RHEL Workstation High Touch Beta with greater detail, but as I don't have private comment powers, I will not detail them here. Bob and Allan know and they can write it as a private comment in this BZ.
