-tails (2.4) UNRELEASED; urgency=medium
+tails (2.4~rc1) unstable; urgency=medium
- * Dummy entry.
+ * Major new features and changes
+ - Upgrade Tor Browser to 6.0 based on Firefox 45.2. (Closes:
+ #11403).
+ - Enable Icedove's automatic configuration wizard. We patch the
+ wizard to only use secure protocols when probing, and only
+ accept secure protocols, while keeping the improvements done by
+ TorBirdy in its own non-automatic configuration wizard. (Closes:
+ #6158, #11204)
+ * Bugfixes
+ - Enable Packetization Layer Path MTU Discovery for IPv4. If any
+ system on the path to the remote host has a MTU smaller than the
+ standard Ethernet one, then Tails will receive an ICMP packet
+ asking it to send smaller packets. Our firewall will drop such
+ ICMP packets to the floor, and then the TCP connection won't
+ work properly. This can happen to any TCP connection, but so far
+ it's been reported as breaking obfs4 for actual users. Thanks to
+ Yawning for the help! (Closes: #9268)
+ - Make Tails Upgrader ship other locales than English. (Closes:
+ #10221)
+ * Minor improvements
+ - Icedove improvements:
+ * Stop patching in our default into Torbirdy. We've upstreamed
+ some parts, and the rest we set with pref branch overrides in
+ /etc/xul-ext/torbirdy.js. (Closes: #10905)
+ * Use hkps keyserver in Engimail. (Closes: #10906)
+ * Default to POP if persistence is enabled, IMAP is
+ not. (Closes: #10574)
+ * Disable remote email account creation in Icedove. (Closes:
+ #10464)
+ - Firewall hardening (Closes: #11391):
+ * Don't accept RELATED packets. This enables quite a lot of code
+ in the kernel that we don't need. Let's reduce the attack
+ surface a bit.
+ * Restrict debian-tor user to NEW TCP syn packets. It doesn't
+ need to do more, so let's do a little bit of security in
+ depth.
+ * Disable netfilter's nf_conntrack_helper.
+ * Fix disabling of automatic conntrack helper assignment.
+ - Kernel hardening:
+ * Set various kernel boot options: slab_nomerge slub_debug=FZ
+ mce=0 vsyscall=none. (Closes: #11143)
+ * Remove the kernel .map files. These are only useful for kernel
+ debugging and slightly make things easier for malware, perhaps
+ and otherwise just occupy disk space. Also stop exposing
+ kernel memory addresses through /proc etc. (Closes: #10951)
+ - Drop zenity hacks to "focus" the negative answer. Jessie's
+ zenity introduced the --default-cancel option, finally!
+ (Closes: #11229)
+ - Drop useless APT pinning for Linux.
+ - Remove gnome-tweak-tool. (Closes: #11237)
+ - Install python-dogtail, to enable accessibility technologies in
+ our automated test suite (see below). (Part of: #10721)
+ - Install libdrm and mesa from jessie-backports. (Closes: #11303)
+ - Remove hledger. (Closes: #11346)
+ - Don't pre-configure the #tails chan on the default OFTC account.
+ (Part of: #11306)
+ - Install onioncircuits from jessie-backports. (Closes: #11443)
+ - Remove nmh. (Closes: #10477)
+ - Drop Debian experimental APT source: we don't use it.
+ - Use APT codenames (e.g. "stretch") instead of suites, to be
+ compatible with our tagged APT snapshots.
+ - Drop module-assistant hook and its cleanup. We've not been using
+ it since 2010.
+ - Remove 'Reboot' and 'Power Off' entries from Applications →
+ System Tools. (Closes: #11075)
+ - Pin our custom APT repo to the same level as Debian ones, and
+ explicitly pin higher the packages we want to pull from our custom
+ APT repo, when needed.
+ - config/chroot_local-hooks/59-libdvd-pkg: verify libdvdcss
+ package installation. (Closes: #11420)
+ - Make Tails Upgrader use our new mirror pool design. (Closes:
+ #11123)

+ * Build system
+ - Use a freezable APT repo when building Tails. This is a first
+ step towards reproducible builds, and improves our QA and
+ development processes by making our builds more predictable. For
+ details, see:
+ - There has been a massive amount of improvements to the
+ Vagrant-based build system, and now it could be considered the
+ de-facto build system for Tails! Improvements and fixes include:
+ * Migrate Vagrant to use libvirt/KVM instead of
+ Virtualbox. (Closes: #6354)
+ * Make apt-get stuff non-interactive while provisioning.
+ Because there is no interaction, so that will results in
+ errors.
+ * Bump disk space (=> RAM for RAM builds) needed to build with
+ Vagrant. Since the Jessie migration it seems impossible to
+ keep this low enough to fit in 8 GiB or RAM. For this reason
+ we also drop the space optimization where we build inside a
+ crazy aufs stack; now we just build in a tmpfs.
+ * Clean up apt-cacher-ng cache on vm:provision to save disk
+ space on the builder.
+ * Add convenient Rake task for SSH:ing into the builder VM:
+ `rake vm:ssh`.
+ * Add rake task for generating a new Vagrant base box.
+ * Automatically provision the VM on build to keep things up-to-date.
+ * Don't enable extproxy unless explicitly given as an
+ option. Previously it would automatically be enabled when
+ `http_proxy` is set in the environment, unlike what is
+ documented. This will hopefully lead to fewer surprises for users
+ who e.g. point http_proxy to a torified polipo, or similar.
+ * Re-fetch tags when running build-tails with Vagrant. That
+ should fix an annoyance related to #7182 that I frequently
+ encounter: when I, as the RM, rebuild the release image the
+ second time from the force-updated tag, the build system would
+ not have the force-updated tag. (Closes: #7182)
+ * Make sure we use the intended locale in the Tails builder VM.
+ Since we communicate via SSH, and e.g. Debian forward the
+ locale env vars by default, we have to take some steps
+ ensuring we do not do that.
+ - Pull monkeysphere from stretch to avoid failing to install under
+ eatmydata. Patch submitted by Cyril Brulebois <>.
+ * Test suite
+ - Add wrapper around dogtail (inside Tails) for "remote" usage in
+ the automated test suite. This provides a simple interface for
+ generating dogtail python code, sending it to the guest, and
+ executing it, and should allow us to write more robust tests
+ leveraging assistive technologies. (Closes: #10721)
+ - A few previously sikuli-based tests has been migrated to use
+ dogtail instead, e.g. GNOME Applications menu interaction.
+ - Add a test for re-configuring an existing persistent volume.
+ This is a regression test for #10809. (Closes: #10834)
+ - Use a simulated Tor network provided by Chutney in the automated
+ test suite. The main motivation here is improved robustness --
+ since the "Tor network" we now use will exit from the host
+ running the automated test suite, we won't have to deal with Tor
+ network blocking, or unreliable circuits. Performance should
+ also be improved. (Closes: #9521)
+ - Drop the usage of Tor Check in our tests. It doesn't make sense
+ now when we use Chutney since that always means it will report
+ that Tor is not being used.
+ - Stop testing obsolete pluggable transports.
+ - Completely rewrite the firewall leak detector to something more
+ flexible and expressive.
+ - Run tcpdump with --immediate-mode for the network sniffer. With
+ this option, "packets are delivered to tcpdump as soon as they
+ arrive, rather than being buffered for efficiency" which is
+ required to make the sniffing work reliable the way we use it.
+ - Remove most scenarios testing "tordate". It just isn't working
+ well in Tails, so we shouldn't expect the tests to actually work
+ all of the time. (Closes: #10440)
