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.

Doc Text:	.The SELinux policy now allows confined administrators to access `ipmi` devices when IPMItool runs Previously, the SELinux policy did not allow confined administrators to read and write `ipmi` devices when the IPMItool utility is run. As a consequence, when a confined administrator ran `ipmitool`, it failed. This update adds allow rules to `selinux-policy` for administrators assigned to the `sysadm_r` SELinux role. As a result, if a confined administrator runs `ipmitool` it works correctly.	Story Points:	---

Description cweather 2022-11-25 22:48:00 UTC

Description of problem:
SELinux is preventing /usr/bin/ipmitool from ioctl access on the chr_file /dev/ipmi0.

Version-Release number of selected component (if applicable):
selinux-policy-3.14.3-108.el8.noarch                        Wed Nov  9 11:19:25 2022
ipmitool-1.8.18-18.el8.x86_64                               Wed Nov 23 07:55:32 2022
Linux cauchy.sd.spawar.navy.mil 4.18.0-425.3.1.el8.x86_64 

How reproducible:
Always

Steps to Reproduce:
1.  Use ipmitool
2.  Recent version of selinux policy
3.  SELinux enabled

Actual results:
Receive AVC denials in /var/log/messages

Expected results:
No AVC denials

Additional info:
The default SELinux policy does not provide the necessary permissions for admins operating under the sysadm_t label to use ipmitool. 

Missing permission appear to be open, read, write, and ioctl on chr_file class with the ipmi_device_t label.

Context: system_u:object_r:ipmi_device_t:s0 /dev/ipmi0
