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 newly added anon_inode class relies on type transitions of the form <domain> <domain>:<typeA> <typeB>. However, SELinux userspace currently doesn't support using the "self" keyword, which makes writing policy for this class tricky. Thus, it is necessary to implement this support so that anon_inode/userfaultfd/io_uring rules can be reasonably implemented in selinux-policy.

I'll be working on the upstream implementation, then I'll switch this to plautrba/vmojzis to handle the backport.

The support is included in the 3.4 upstream release, so closing this as duplicate of BZ 2079276.

*** This bug has been marked as a duplicate of bug 2079276 ***

Reopening after discussion with plautrba and mmalik.
