Description of problem:
after enabling kdbus
SELinux is preventing systemd-localed from 'ioctl' accesses on the file /sys/fs/kdbus/0-system/bus.

*****  Plugin restorecon (99.5 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 (1.49 confidence) suggests   **************************

If you believe that systemd-localed should be allowed ioctl 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-localed /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
