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 Adam Kropelin 2015-02-04 16:08:09 UTC
Created attachment 988166 [details]
local policy file for apcupsd libusb usage

Beginning with version 3.14.13, apcupsd utilizes libusb. This requires an selinux policy update to allow the daemon access to /sys/bus/usb.

aureport for relevant events:

982. 02/04/2015 10:59:57 apcupsd system_u:system_r:apcupsd_t:s0 257 dir read system_u:object_r:sysfs_t:s0 denied 628
983. 02/04/2015 10:59:57 apcupsd system_u:system_r:apcupsd_t:s0 4 lnk_file read system_u:object_r:sysfs_t:s0 denied 629
984. 02/04/2015 10:59:57 apcupsd system_u:system_r:apcupsd_t:s0 4 file getattr system_u:object_r:sysfs_t:s0 denied 629
985. 02/04/2015 10:59:57 apcupsd system_u:system_r:apcupsd_t:s0 2 file read system_u:object_r:sysfs_t:s0 denied 630
986. 02/04/2015 10:59:57 apcupsd system_u:system_r:apcupsd_t:s0 2 file open system_u:object_r:sysfs_t:s0 denied 630

A local policy to allow sysfs access for apcupsd is attached. If there is a standard set of rules for general libusb clients, it would be appropriate to apply those instead.
