Description of problem: SELinux is preventing dbus-broker from 'write' accesses on the fifo_file /run/boltd/power/2.guard.fifo. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that dbus-broker should be allowed write access on the 2.guard.fifo fifo_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 'dbus-broker' --raw | audit2allow -M my-dbusbroker # semodule -X 300 -i my-dbusbroker.pp Additional Information: Source Context system_u:system_r:system_dbusd_t:s0-s0:c0.c1023 Target Context system_u:object_r:boltd_var_run_t:s0 Target Objects /run/boltd/power/2.guard.fifo [ fifo_file ] Source dbus-broker Source Path dbus-broker Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.2-36.fc29.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.18.13-300.fc29.x86_64 #1 SMP Wed Oct 10 17:22:50 UTC 2018 x86_64 x86_64 Alert Count 7 First Seen 2018-10-11 20:55:26 EDT Last Seen 2018-10-12 07:44:33 EDT Local ID e91168df-a421-4c59-b3a0-8a86ade4c6e0 Raw Audit Messages type=AVC msg=audit(1539344673.249:326): avc: denied { write } for pid=1047 comm="dbus-daemon" path="/run/boltd/power/2.guard.fifo" dev="tmpfs" ino=60923 scontext=system_u:system_r:system_dbusd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:boltd_var_run_t:s0 tclass=fifo_file permissive=0 Hash: dbus-broker,system_dbusd_t,boltd_var_run_t,fifo_file,write Version-Release number of selected component: selinux-policy-3.14.2-36.fc29.noarch Additional info: component: selinux-policy reporter: libreport-2.9.6 hashmarkername: setroubleshoot kernel: 4.18.13-300.fc29.x86_64 type: libreport
