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.
DescriptionFlorin Asavoaie

Description of problem:
mdadm not allowed to search /sys/firmware/efi/efivars/.
Version-Release number of selected component (if applicable):
mdadm-3.3.2-7.el7.x86_64
selinux-policy-targeted-3.13.1-60.el7_2.3.noarch
How reproducible:
In my case, I have a RAID 1 volume with Intel RST, managed by mdadm. When I do "fdisk /dev/md126" and then hit "w" to save changes, even if I did not change anything, I get an Audit alert that mdadm is denied to access /sys/firmware/efi/efivars/.
Was not able to check if it is reproducible with other types of RAID arrays created with mdadm or anything.
Here is the output of audit2allow:
[root@pc ~]# audit2allow -a
#============= mdadm_t ==============
allow mdadm_t efivarfs_t:dir search;
Steps to Reproduce:
1. Check the previous section.
Actual results:
Selinux denies access to mdadm to something that appears to be required.
Expected results:
mdadm is able to access all the hardware and other information it needs.
Additional info:
I am not able to detect what functional issues are caused by this behavior, I only noticed the audit notification.
