I can confirm this bug, it appears since systemd was upgraded to version 239-6 : SELinux is preventing systemd-logind from open access on the blk_file /dev/sdb1. The systemd packages were updated today, after every reboot the warning appears, and even after applying the suggested policy module the warning message appears. commit 5a103fd1d605fb1195fbfb02361a723d0f7669aa (HEAD -> rawhide, origin/rawhide)

Description of problem: SELinux is preventing systemd-logind from 'ioctl' accesses on the blk_file /dev/sda. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that systemd-logind should be allowed ioctl access on the sda blk_file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'systemd-logind' --raw | audit2allow -M my-systemdlogind # semodule -X 300 -i my-systemdlogind.pp Additional Information: Source Context system_u:system_r:systemd_logind_t:s0 Target Context system_u:object_r:fixed_disk_device_t:s0 Target Objects /dev/sda [ blk_file ] Source systemd-logind Source Path systemd-logind Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.2-40.fc29.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.18.16-300.fc29.x86_64 #1 SMP Sat Oct 20 23:24:08 UTC 2018 x86_64 x86_64 Alert Count 18 First Seen 2018-11-02 17:59:21 CET Last Seen 2018-11-02 17:59:21 CET Local ID c2f0aee3-da97-4e9d-9cef-570e43e9058d Raw Audit Messages type=AVC msg=audit(1541177961.531:471): avc: denied { ioctl } for pid=987 comm="systemd-logind" path="/dev/sda" dev="devtmpfs" ino=1119 ioctlcmd=0x1268 scontext=system_u:system_r:systemd_logind_t:s0 tcontext=system_u:object_r:fixed_disk_device_t:s0 tclass=blk_file permissive=0 Hash: systemd-logind,systemd_logind_t,fixed_disk_device_t,blk_file,ioctl Version-Release number of selected component: selinux-policy-3.14.2-40.fc29.noarch Additional info: component: selinux-policy reporter: libreport-2.9.6 hashmarkername: setroubleshoot kernel: 4.18.16-300.fc29.x86_64 type: libreport
