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.
