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 of problem:
IPC access control files override each other if more apply to a user.

Version-Release number of selected component (if applicable):


How reproducible:
always

Steps to Reproduce:

1. let's have a user bob (uid 1000) who is a member of a group bob (gid 1000)
2. create two IPC files, one for the user (Devices=list) and one for the group (Policy=list)
root# usbguard add-user 1000 -d list
root# usbguard add-user -g 1000 -p list
3. restart usbguard daemon and try executing the following commands with user bob
bob$ usbguard list-devices
1: allow ... OK, prints out devices
bob$ usbguard list-rules
IPC ERROR: request id=1: IPC method: usbguard.IPC.listRules: Permission denied

Actual results:
User bob can not list usbguard rules despite being a member of group bob that has permissions Policy=list

Expected results:
A list of rules would show up
