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.
.Fixed SELinux policy interface parser
Previously, the policy interface parser caused syntax error messages to appear when installing a custom policy that contained an `ifndef` block in its interface file. This update improves the interface file parsing, and thus resolves this issue.
Description of problem:
When updating or installing a specific selinux-policy-devel package, the following errors appear:
Running transaction
Preparing : 1/1
Upgrading : selinux-policy-3.14.3-52.el8.noarch 1/6
Running scriptlet: selinux-policy-3.14.3-52.el8.noarch 1/6
Upgrading : selinux-policy-devel-3.14.3-52.el8.noarch 2/6
Running scriptlet: selinux-policy-devel-3.14.3-52.el8.noarch 2/6
/usr/share/selinux/devel/include/contrib/ipa.if: Syntax error on line 323 interface [type=INTERFACE]
/usr/share/selinux/devel/include/contrib/ipa.if: Syntax error on line 329 ' [type=SQUOTE]
The update continues without any apparent problem. As /usr/bin/sepolgen-ifgen is the only command executed in the postinstall scriptlet, it may not work out properly interface definition inside a conditional block:
322 ifndef(`ipa_helper_noatsecure',`
323 interface(`ipa_helper_noatsecure',`
324 gen_require(`
325 type ipa_helper_t;
326 ')
327
328 allow $1 ipa_helper_t:process { noatsecure };
329 ')
330 ')
Version-Release number of selected component (if applicable):
policycoreutils-devel-2.9-9.el8.x86_64
How reproducible:

Steps to Reproduce:
1. dnf update selinux-policy-3.14.3-52.el8.noarch
