[03:08] <jamesh> amurray: hi. I ran into some problems with the cups interface, and was trying to work out whether I'm misreading the AppArmor rules or if they're just buggy.
[03:09] <jamesh> amurray: there are a bunch of dbus rules using "peer=(name=org.freedesktop.DBus,label=unconfined)," (or similar but allowing different labels)
[03:10] <jamesh> amurray: which looks weird since no peer is going to be able to own org.freedesktop.DBus (it is reserved for dbus-daemon)
[03:11] <jamesh> also, are the "name=" and "label=" parts of the clause combined with an "AND" or an "OR"?
[03:11] <jamesh> the apparmor.d man page wasn't much help in determining the answer to that last one
[03:19] <amurray> jamesh: yeah I have been confused by that in the past too... let me see if I have any notes on that as I am not sure off the top of my head (I had thought it was 'AND' semantics - ie the peer has to be both unconfined and own the name)
[03:21] <jamesh> amurray: my understanding was that jdstrand added the name= clause to a lot of these rules to handle D-Bus activatable services (where we don't know the peer label until after the message has been approved/rejected)
[03:21] <jamesh> but a peer can't own org.freedesktop.DBus...
[03:23] <jamesh> amurray: the specific problem was in the cupsControlConnectedPlugAppArmor policy fragment: removing the name= part allowed messages to be received
[03:25] <jamesh> I don't think the D-Bus activation reason really makes sense here either: if we're processing a receive rule, then the sender is already running and we'll know its AppArmor label.
[03:26] <amurray> yeah I saw till's discussion of that - so the only other instances of name=org.freedesktop.DBus that I can see in snapd apparmor rules are for talking to dbus itself - so perhaps these (for /org/cups/cupsd/Notifier) were just wrong to begin with
[03:28] <jamesh> Okay. I'll make a PR to update the cups-control interface here (Till was running into it). There seem to be a bunch of other interfaces with dubious rules using name=org.freedesktop.DBus where dbus-daemon isn't the source/destination
[03:29] <amurray> sounds good
[03:31] <jamesh> Thanks.
[03:32] <amurray> I see a bunch in desktop-legacy, desktop, unity7 - I think these should also be updated to remove the name=org.freedesktop.DBus bit
[03:33] <jamesh> or work out what the appropriate bus name should be
[03:38] <amurray> yes that would probably be better
[03:39] <jamesh> It'd be good to deprecate unity7 at some point
[03:41] <jamesh> Anything still useful should be provided by one of combination of desktop and desktop-legacy
