- Run ping as root (aufs does not support file capabilities so we don't
get cap_net_raw+ep, and if built on a filesystem that does support
file capabilities, then /bin/ping is not setupd root).
* Fix is_persistent?() helper due to findmnt changes in Jessie.
In jessie, findmnt correctly notices that / is an aufs mounts. Hence
let's assume that we're not using read-only persistence (which uses
aufs) in which case aufs => no persistence.
* Rework how we measure pattern coverage.
The approaches we used before just seems incorrect in multiple ways:
* vm.overcommit_memory = 2 seems to make OOM killing happen way too
early, around when 15% or RAM is still free, no matter the value of
vm.overcommit_ratio and the various *reserved settings.
* Using the ratio of a ration for the {min,max}_coverage calculations
were just weird and a sign of incremental bandaid-like fixes.
Now we do what we intended more explicitly, that is: measure the
pattern coverage in the free RAM at the time we start filling it. We
also have to reserve some RAM for the kernel (so it doesn't freeze
when approaching full RAM) and admin processes like the remote shell
(so it doesn't get unresponsive), and we exclude this from the free
RAM in the calculations for a much more accurate result than before.
Note that we may end up having a bit more than 100% pattern
coverage. While that may seem strange it may just indicate that some
unrelated RAM was freed after we noted the amount of free RAM right
before we started filling it.
Will-fix: #9705
* Use blkid instead of parted to determine the filesystem type.
In Jessie, "parted print NUMBER" doesn't work, and then blkid seems
like a cleaner approach (bonus: the name blkid uses for swap is
cleaner too).
* Simplify by removing the wait_for_gnome*() helpers.
They don't work well and do not seem needed. Also, it's used in only
two places, and add to that that GNOME seems to be moving away from
having the type of title bar we're looking for.
* Start each fillram instance with the correct oom_score_adj.
... by starting them in sub shell with the desired oom_score_adj. The
way we did it before left a window where they inherit the remote
shell's oom_score_adj, which is the absolute opposite of the range,
meaning that everything else will be prioritized.
* Decide memory wiping waiting time on configured RAM.
... instead of detected RAM. This should only make us wait longer,
since detected RAM <= configured RAM, so it's safe but potentially an
increase in runtime.
We actually do this since we often want to run these modified steps
when the remote shell is not available any more, since Tails is
shutting down.
* Use --kiosk mode instead of --fullscreen in virt-viewer.
The only effect will be that the tiny border of the in-viewer menu is
removed (which *potentially* could be in the way some time) since
--kiosk implies --fullscreen.
* Remove scenario.
In Jessie, org.gnome.gnome-screenshot.auto-save-directory is empty
since the default is sensible, ~/Pictures. To save the removed
scenario we'd have to set it explicitly, which seems stupid. Besides,
the 'A screenshot is taken when the PRINTSCREEN key is pressed'
scenario is already testing that GNOME Screenshot saves into this
directory, which is enough.
* Adapt Gnome notification handling for Debian Jessie.
When waiting for specific notifications we'll completely depend on
robust_notification_wait() from now on *and* it will leave other
notifications unlike the old version.
Will-fix: #8782
* Migrate to robust_notification_wait() and update some related images for Jessie.
* Adjustments for Debian 8 (Jessie) with no or very little user-visible impact
- Free the fixed UIDs/GIDs we need before creating the corresponding users.
- Disable /etc/network/if-pre-up.d/macchanger (Closes: #8265).
On Jessie, macchanger ships /etc/network/if-pre-up.d/macchanger, that
probably conflicts with the way we're spoofing MAC addresses.
- Replace the real gnome-backgrounds with a fake, equivs generated one
(Closes: #8055). Jessie's gnome-shell depends on gnome-backgrounds,
which is too fat to ship considering we're not using it.

- Don't explicitly install gnome-panel nor gnome-menus, so that they go away
whenever the Greeter does not pull them in anymore.
- Install gkbd-capplet, that provides gkbd-keyboard-display (Closes: #8363).
- Install Tor 0.2.7 from deb.torproject.org: we don't need to rebuild it

mixer levels are unmuted and sanitized at boot time (Closes: #7591).

It has never been used in Tails, and has finally been removed on Jessie:
per-user sessions for everyone.

* Don't install gnome-panel nor gnome-menus.
They're not needed in GNOME Shell anymore. We still get them by way of the
dependency from the GNOME Flashback stack (used in the Greeter), and they
will go away whenever the Greeter runs in GNOME Shell.

* Drop notification for not-migrated-yet persistence configuration.
That migration happened in Tails 0.21, released on 2013-10-29.
* Add a unit file whose completion indicates that Tor has bootstrapped.
We'll then be able to use this, with systemd units ordering, to get rid
of some of the while/sleep loops we have elsewhere.

* Test suite: run ping as root.
For some reason, on Jessie, running ping as a regular users results in "ping:
icmp open socket: Operation not permitted", with exit code == 2. But as root, it
"works" and the firewall blocks the packets. This is rather an improvement than
a problem (stuff is blocked earlier, which is cheaper), so let's just deal with
it in the test suite only, by running ping as root: the main purpose here is to
test the firewall.
This change also affects the netcat command used to open TCP and UDP
connections, for code simplicity's sake. Here again, the goal is to test
the firewall.

It's been there since the first commit, mostly because back in the

Refs: #8263
Since then, we've bumped the memory requirements (both in our
documentation and on the test suite's "hardware") to 2 GB, so the
original reason for this change has gone away => let's go back to
a value that was tested and confirmed to work (as in: allow upgrading
a running Tails) on Wheezy, instead of a value that was tested on
Jessie, but only for checking for available upgrades.
The follow-ups will be:
* the cool ideas posted on
https://labs.riseup.net/code/issues/8263#note-1 will become a new,
dedicated ticket (that has no reason to block the Tails 2.0 release);
* #8083 and #7986 will tell us if the value this commit reverts to
is OK.
* Upgrader wrapper: make the check for free memory smarter.
Quoting anonym (#8263#note-1):
In our Live system context, where a lot of stuff is in tmpfs:es, looking
at the values of free or /proc/meminfo alone isn't accurate for
determining how much memory "really" is free, since the tmpfs usage is
included in the buffers. Hence, MemFree is the lower (and safe) bound of
how much "really" free memory we have, and MemFree + Buffers + Cache is
the upper (and unsafe) bound. The true value should be (at least closer
to) MemFree + Buffers + Cache - (sum of usage by tmpfs:es). We should
check once against that value instead.
The 300 MB magic number (minimum "real memory" available) was found
after bisecting with an ISO built from current feature/jessie:
* with 278000 kB of "real memory" available, Tails Upgrader could
successfully tell me that no upgrade was available (which is indeed
the case), or that I should manually upgrade (after tweaking
/etc/os-release; because I started from DVD);
* with 255000 kB of "real memory" available, the check for upgrades
failed and the desktop session froze;
=> so 300x1024 kB should give us a small safety margin.
For the record, a VM with 1GB of RAM allocated (891 MB visible due to
the QXL video adapter stealing some) on current feature/jessie has
336MB (137MB free + 39MB buffers + 212MB cache - 52MB tmpfs) of "real
memory" available once Tor is ready and Tor Browser is started, so in
practice any system that's beefy enough to use Tails 2.0 can check
for upgrades.
Closes: #10540, #8263
* Drop notification when persistence settings were disabled due to wrong access rights.
No need to run this script at login time on every Tails two years later.

As explained on https://labs.riseup.net/code/issues/8328#note-5, it's
been broken for 16 months, it is still broken after the partial fix that
went in Tails 1.6, and the logic on which the detector is based cannot
work anymore. Reintroducing and porting this feature is now tracked
on #10560.
Closes: #8328
Refs: #10560
* Don't try to disable lvm2 initscripts anymore.
It was disabled in amnesia 0.3 because "it slows-down too much the boot
in certain circumstances". I can't confirm that with current hardware on
feature/jessie: the output of `systemd-analyze critical-chain' does not
include anything LVM-related, and in `systemd-analyze blame' everything
LVM-related takes 400ms or less on one of my systems, and 100ms or less
on another.
On Jessie, lvm2 initscripts have been split into numerous systemd units,
so it might help avoid unconditionally blocking boot.

on Jessie.
