Description

Like network cards, Bluetooth devices have MAC addresses which can potentially identify a user.

Bluetooth is enabled by default in Tails but we do not ship the corresponding userspace software stack. We now have a feature request to make it possible to disable bluetooth on boot/in the greeter.

Also see https://labs.riseup.net/code/projects/tails/repository/revisions/613b14c689c9b5d94361e90d4f9623fc27fdcef9/entry/wiki/src/doc/advanced_topics/wireless_devices.mdwn

A plan could be:

  • at build time, blacklist bluetooth (bluetooth stack)
  • at (early) boot, rfkill block bluetooth config/chroot_local-includes/usr/local/sbin/tails-set-wireless-devices-state
  • in the Greeter, allow opting-in for Bluetooth
    • in PostLogin.default, pass Bluetooth user prefs to tails-unblock-network
    • in tails-unblock-network, if Bluetooth is enabled, remove the blacklist file and rfkill unblock bluetooth
  • later
    • for added safety, disable system-wide daemon and/or move gnome-bluetooth files out of the way?
    • hardware-dependent device drivers?
    • support enabling Bluetooth post-login if I forgot?

I had a go on a patch to disable BT and enabling it later on in the greeter. The patch is older then one year an possibly completely outdated. Still useful might be the /etc/modprobe.d/blacklist-bluetooth.conf file

—- cut here —-
install bluetooth /bin/false
blacklist bnep
blacklist btusb
blacklist bluetooth
—- cut here —-

The first line is important since the ‘blacklist’ keyword doesn’t seem to be effective if the bluetooth module is load as a dependency.

I think that other bits of the patch (especially the non-GUI parts that enable bluetooth if the user wants it) can still be very useful!

Sure! Thanks a lot :)
