Supported interfaces


#21

Note that the unity7 interface also grants access to X: The desktop interfaces


#22

Subject snaps are in strict confinement as the “info --verbose” output states. When other interfaces disconnected desired effects are visible which i think shows that confinement working also no Mir or Wayland on machine only Xorg installed and active.

it still works after restart.


#23

Does unity7 interface suffers the same X11 interface security flaws? i’m using Xorg as DS and lightdm as DM. My guess is yes since it still uses Xorg as server but i’m curious if there is a security hardening at unity level.


#24

Unity7 is a window manager for X and as such, applications that run under Unity7 must necessarily be able to talk to X, therefore all the same flaws are present. You might be thinking of Unity8 which used Mir instead of X and by design, Mir didn’t suffer from the same issues. At some point, window managers that sit on top of wayland implementations will be widely used and we can drop the reliance on X, ideally leaving the x11 (and unity7) snapd plugs as manually connected for those that need it. We aren’t there yet, but I have every expectation that some day we’ll get there.


#25

until then can snap implement nested X approach or X11 bridge approach at least as an option for security sensitive use cases. X11docker and Subuser doing it for docker containers with help of Xephyr, Xpra … but they are not convenient and stable as snap. It will be great if this was a option for snap it will make snap one stop shop.

Right now i’m using x11docker for experimental wild wild west applications and boy it is painful to do. And snap for applications i was already using for long time and have some trust on them.
