Author: cem Date: Wed Nov 1 18:58:54 2017 New Revision: 325287 URL: https://svnweb.freebsd.org/changeset/base/325287 Log: bluetooth: Default to discoverable off Try to not expose bluetooth devices to external devices unless the user explicitly configures it, like any other radio/network device. Bluetooth has a long history of security problems and it is probably best to keep it disabled if not needed. Users who do use the bluetooth device should enable "discoverable" in bluetooth.device.conf(5) after this change. Keep in mind that bluetooth addresses can be discovered by passive monitoring or whole address-space scans[0], so a safety conscious user should also disable "connectable" in bluetooth.device.conf(5).
