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 Jan Stodola 2023-01-26 16:11:43 UTC 
Description of problem:
The following AVC appeared in audit.log after the default package set installation on aarch64 in FIPS mode ("fips=1" on the kernel command line):

type=AVC msg=audit(1674742919.572:45): avc:  denied  { read } for  pid=1003 comm="systemctl" name="cpuinfo" dev="proc" ino=4026531987 scontext=system_u:system_r:NetworkManager_dispatcher_iscsid_t:s0 tcontext=system_u:object_r:proc_t:s0 
tclass=file permissive=0



Version-Release number of selected component (if applicable):
RHEL-9.2.0-20230125.12
selinux-policy-38.1.4-1.el9

How reproducible:
Always on aach64

Steps to Reproduce:
1. Run installation on aarch64 with "fips=1" on the kernel command line. Install the default package set.
2. Check /var/log/audit/audit.log on the installed system.

Actual results:
AVC denials

Expected results:
No AVC

Additional info:
So far reproduced just on aarch64 and only in FIPS mode.
