The IPv6 Neighbor Discovery protocol (RFC 2461) suggests
implementations provide MTU in Router Advertisement (RA)
messages. From section 4.2
MTU SHOULD be sent on links that have a variable MTU
(as specified in the document that describes how to
run IP over the particular link type). MAY be sent
on other links.
dnsmasq supports this option and should have read access
to an interface's MTU.

possibly be excluded, but applications using networking (at least on Ubuntu)

Ubuntu 14.04's chromium-browser has changed paths in a way that prevents
evince from opening clicked links in chromium-browser windows.
This patch adds a new path for the chrome-sandbox executable to the
sanitized_helper profile, so chromium will get its own tailored profile if
necessary.
The reporter who said this patch helped included some further DENIED lines
for signals that indicates this is probably not sufficient but did make
the links work as expected.

the suggestion to use @{XDG_DOWNLOAD_DIR} in abstractions/user-download as
well as the existing entries.
Acked-By: Jamie Strandboge <jamie@canonical.com>
Acked-By: Christian Boltz <apparmor@cboltz.de>
The xdg-user-dirs specification[1] allows for translatable and movable common
directories. While this may be beneficial for users who for example want to have
~/Pictures translated into their own language, this flexibility provides
challenges for AppArmor. Untranslated xdg user directories are typically (see
~/.config/user-dirs.dirs):
XDG_DESKTOP_DIR="$HOME/Desktop"
XDG_DOWNLOAD_DIR="$HOME/Downloads"
XDG_TEMPLATES_DIR="$HOME/Templates"
XDG_PUBLICSHARE_DIR="$HOME/Public"
XDG_DOCUMENTS_DIR="$HOME/Documents"
XDG_MUSIC_DIR="$HOME/Music"
XDG_PICTURES_DIR="$HOME/Pictures"
XDG_VIDEOS_DIR="$HOME/Videos"
On an Ubuntu system with the fr_CA locale installed, these become:
XDG_DESKTOP_DIR="$HOME/Desktop"
XDG_DOWNLOAD_DIR="$HOME/Téléchargements"
XDG_TEMPLATES_DIR="$HOME/Templates"
XDG_PUBLICSHARE_DIR="$HOME/Public"
XDG_DOCUMENTS_DIR="$HOME/Documents"
XDG_MUSIC_DIR="$HOME/Musique"
XDG_PICTURES_DIR="$HOME/Images"
XDG_VIDEOS_DIR="$HOME/Vidéos"
While the kernel and AppArmor parser handle these translations fine, the
profiles do not.
As an upstream, we can vastly improve the situation by simply creating the
xdg-user-dirs tunable using the default 'C' xdg-user-dirs values:
$ cat /etc/apparmor.d/tunables/xdg-user-dirs
@{XDG_DESKTOP_DIR}=Desktop
@{XDG_DOWNLOAD_DIR}=Downloads
@{XDG_TEMPLATES_DIR}=Templates
@{XDG_PUBLICSHARE_DIR}=Public
@{XDG_DOCUMENTS_DIR}=Documents
@{XDG_MUSIC_DIR}=Music
@{XDG_PICTURES_DIR}=Pictures
@{XDG_VIDEOS_DIR}=Videos
# Also, include files in tunables/xdg-user-dirs.d for site-specific adjustments
# to the various XDG directories
#include <tunables/xdg-user-dirs.d>
and then create the /etc/apparmor.d/tunables/xdg-user-dirs.d directory. With
that alone, we can start using rules like this in policy:
owner @{HOME}/@{XDG_MUSIC_DIR}/** r,
and users/admins can adjust /etc/apparmor.d/tunables/xdg-user-dirs or drop files
into /etc/apparmor.d/tunables/xdg-user-dirs.d, providing a welcome convenience.
This of course doesn't solve everything. Because users can modify their
~/.config/user-dirs.dirs file at will and have it point anywhere, so we can't
examine those files and do anything automatic there (when we have user policy we
can revisit this). This patch handles translations well though since use of
translations for these directories happens outside of the user's control. Users
who modify ~/.config/user-dirs.dirs can update policy like they need to now (ie,
this patch doesn't change anything for them).

This patch adds basic support for XDG user dirs:
1. Update profiles/apparmor.d/tunables/global to include xdg-user-dirs.
2. Create the xdg-user-dirs tunable using the default 'C' xdg-user-dirs values
and includes tunables/xdg-user-dirs.d
3. Add profiles/apparmor.d/tunables/xdg-user-dirs.d/site.local with commented
out examples on how to use the directory.
