** Description changed:
On Ubuntu 14.10, I had this in my logs:
Jan 21 16:32:30 localhost kernel: [24900.927939] audit: type=1400

$ aa-decode 676F6F676C652D6E61636C2D6

So I tried the following:
unix bind type=dgram addr=@google-nacl*,
unix bind type=dgram addr="@google-nacl*",
unix bind type=dgram addr=@676F6F676C652D6E61636C2D6*,
unix bind type=dgram addr="@676F6F676C652D6E61636C2D6*",
+ unix bind type=dgram addr=@google-nacl*\\000*,
+ unix bind type=dgram
addr=@google-nacl*[0-9a-zA-Z]\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000\\000{,\\000,\\000\\000},
+
but none of them match. The best I could do was:
unix bind type=dgram,
This is likely going to be important for snappy since snappy will have the
concept of different coordinating snaps interacting via abstract sockets. What
is interesting is that this seems to work ok for some things, eg:
./lightdm: unix (bind, listen) type=stream
addr="@/com/ubuntu/upstart-session/**",
./lightdm: unix (bind, listen) type=stream addr="@/tmp/dbus-*",
./lightdm: unix (bind, listen) type=stream addr="@/tmp/.ICE-unix/[0-9]*",
./lightdm: unix (bind, listen) type=stream addr="@/dbus-vfs-daemon/*",
./lightdm: unix (bind, listen) type=stream addr="@guest*",
Is this something in how firefox is setting up the socket?

google hangout.
