Description of problem: The iscsiuio process cannot configure the network settings of bnx2i or qedi iSCSI HBAs from userspace, as access to the UIO devices is now being blocked. I'm not sure what or when the impacting policy change was. Version-Release number of selected component (if applicable): selinux-policy-3.13.1-221.el7.noarch How reproducible: 100% Steps to Reproduce: 1. configure iface.ipaddress on offload iface 2. attempt iSCSI SendTargets discovery over the offload iface Actual results: iscsiadm: Connection to discovery portal 172.17.20.18 failed: operation failed but retry may succeed iscsiadm: Could not set host net params (err 29) Expected results: configure HBA and connect to iSCSI target Additional info: type=AVC msg=audit(1535562523.017:109): avc: denied { map } for pid=15918 comm="iscsiuio" path="/dev/uio0" dev="de0 Was caused by: Missing type enforcement (TE) allow rule. You can use audit2allow to generate a loadable module to allow this access. #============= iscsid_t ============== allow iscsid_t userio_device_t:chr_file map;
