Title:

Hi Dave
There's a new apparmor_4.1.0~beta5-0ubuntu5 available in plucky-proposed that
should remove the wpa_supplicant apparmor profile. We decided to disable it by
default for now in Ubuntu
I added a comment in the upstream MR for the profile fix, feel free to add more
details there if you wish
Sorry to be the bearer of bad news: unfortunately this still appears
broken on certain platforms. Specifically, testing a fresh plucky image
on the Raspberry Pi, the wifi interface was recognized but not
configured:
$ ip a

default qlen 1000
This bug was fixed in the package apparmor - 4.1.0~beta5-0ubuntu4

Hi Khairul.
Unfortunately the fix was not complete and there's a 4.1.0~beta5-0ubuntu5 on
the way. What you can do now is unload the profile and remove it.
# apparmor_parser --remove /etc/apparmor.d/wpa_supplicant
# rm /etc/apparmor.d/wpa_supplicant

The first denial I am seeing is for netlink. So
network (create) netlink raw,
I am assuming once it is allowed creation of the netlink socket their
will be addition permissions needed.

Seems like the new wpa_supplicant protocol will need rules allowing read
access to /sys/devices/pci*:*/*:*:*.*/ieee80211/phy*/** and to allow
dgram socket creation, but there may be other accesses we might have
missed that would be needed to unbreak the profile. For now, we'll
proceed by disabling
