Description of problem: kdbus=1 SELinux is preventing systemd-hostnam from 'open' accesses on the file /sys/fs/kdbus/0-system/bus. ***** Plugin restorecon (94.8 confidence) suggests ************************ If you want to fix the label. /sys/fs/kdbus/0-system/bus default label should be sysfs_t. Then you can run restorecon. Do # /sbin/restorecon -v /sys/fs/kdbus/0-system/bus ***** Plugin catchall_labels (5.21 confidence) suggests ******************* If you want to allow systemd-hostnam to have open access on the bus file Then you need to change the label on /sys/fs/kdbus/0-system/bus Do # semanage fcontext -a -t FILE_TYPE '/sys/fs/kdbus/0-system/bus' where FILE_TYPE is one of the following: abrt_helper_exec_t, abrt_var_run_t, bin_t, boot_t, cluster_conf_t, cluster_var_lib_t, cluster_var_run_t, cpu_online_t, dbusd_etc_t, etc_runtime_t, etc_t, fail2ban_var_lib_t, file_context_t, fonts_cache_t, fonts_t, hostname_etc_t, ld_so_cache_t, ld_so_t, lib_t, locale_t, machineid_t, man_cache_t, man_t, mandb_cache_t, prelink_exec_t, proc_t, proc_xen_t, rkhunter_var_lib_t, rpm_script_tmp_t, selinux_config_t, shell_exec_t, sosreport_tmp_t, src_t, sysfs_t, system_conf_t, system_db_t, system_dbusd_var_lib_t, systemd_home_t, systemd_hostnamed_exec_t, textrel_shlib_t, usr_t. Then execute: restorecon -v '/sys/fs/kdbus/0-system/bus' ***** Plugin catchall (1.44 confidence) suggests ************************** If you believe that systemd-hostnam should be allowed open access on the bus 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: # grep systemd-hostnam /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:systemd_hostnamed_t:s0 Target Context system_u:object_r:unlabeled_t:s0 Target Objects /sys/fs/kdbus/0-system/bus [ file ] Source systemd-hostnam Source Path systemd-hostnam Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-138.fc24.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 4.2.0-0.rc4.git4.1.fc24.x86_64 #1 SMP Fri Jul 31 16:32:22 UTC 2015 x86_64 x86_64 Alert Count 4 First Seen 2015-08-01 13:52:40 MSK Last Seen 2015-08-01 16:43:54 MSK Local ID f3a6c334-01bd-4895-bf21-3f0613a316ac Raw Audit Messages type=AVC msg=audit(1438436634.717:3169812): avc: denied { open } for pid=30548 comm="systemd-hostnam" path="/sys/fs/kdbus/0-system/bus" dev="kdbusfs" ino=4 scontext=system_u:system_r:systemd_hostnamed_t:s0 tcontext=system_u:object_r:unlabeled_t:s0 tclass=file permissive=1 Hash: systemd-hostnam,systemd_hostnamed_t,unlabeled_t,file,open Version-Release number of selected component: selinux-policy-3.13.1-138.fc24.noarch Additional info: reporter: libreport-2.6.2 hashmarkername: setroubleshoot kernel: 4.2.0-0.rc4.git4.1.fc24.x86_64 type: libreport
