Hi min-soo-cho - this fix has not yet been released in the upstream apparmor project so I'm changing this back to 'fix committed'
** Changed in: apparmor Status: Fix Released => Fix Committed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1231778 Title: wifi not working on Saucy Salamander Status in Enablement project for the Toshiba AC100 NetBook: New Status in AppArmor Linux application security framework: Fix Committed Status in “apparmor” package in Ubuntu: Fix Released Status in “network-manager” package in Ubuntu: Invalid Status in “apparmor” source package in Saucy: Fix Released Status in “network-manager” source package in Saucy: Invalid Status in “apparmor” source package in Trusty: Fix Released Status in “network-manager” source package in Trusty: Invalid Bug description: [Impact] On older kernels that are missing certain AppArmor patches related to AppArmor D-Bus mediation, the presence of dbus rules in the binary AppArmor policy will result in policy load failures and, as a result, applications may run unconfined. On newer kernels that are missing the same patches mentioned above, the policy load will succeed but the dbus rules will be quietly ignored. [Automated Test Case] * test_lp1231778 has been added to QRT's test-apparmor.py script * Run the test under the latest Saucy, Raring, and Lucid kernels to excercise all possible test load scenarios [Manual Test Case] * Install and reboot into older, unpatched mainline kernel (such as 3.1.10-030110-generic) * Bad test results on the mainline 3.1.10 kernel: $ echo "/t { dbus, }" | sudo apparmor_parser -r Cache read/write disabled: /sys/kernel/security/apparmor/features interface file missing. (Kernel needs AppArmor 2.4 compatibility patch.) Warning from stdin (line 1): apparmor_parser: cannot use or update cache, disable, or force-complain via stdin apparmor_parser: Unable to replace "/t". Profile doesn't conform to protocol * Good test results on the mainline 3.1.10 kernel with a patched apparmor_parser: $ echo "/t { dbus, }" | sudo apparmor_parser -r Cache read/write disabled: /sys/kernel/security/apparmor/features interface file missing. (Kernel needs AppArmor 2.4 compatibility patch.) Warning from stdin (line 1): apparmor_parser: cannot use or update cache, disable, or force-complain via stdin Warning from stdin (stdin line 2): profile /t dbus rules not enforced * Install and reboot into newer, unpatched mainline kernel (such as 3.12.0-031200-generic) * Bad test results on the mainline 3.12.0 kernel: $ echo "/t { dbus, }" | sudo apparmor_parser -r Warning from stdin (line 1): apparmor_parser: cannot use or update cache, disable, or force-complain via stdin * Good test results on the mainline 3.12.0 kernel with a patched apparmor_parser: $ echo "/t { dbus, }" | sudo apparmor_parser -r Warning from stdin (line 1): apparmor_parser: cannot use or update cache, disable, or force-complain via stdin Warning from stdin (stdin line 2): profile /t dbus rules not enforced * Reboot into Ubuntu 3.11.0-12-generic kernel * Good test results on the Ubuntu 3.11.0-12-generic kernel with or without a patched apparmor_parser: $ echo "/t { dbus, }" | sudo apparmor_parser -r Warning from stdin (line 1): apparmor_parser: cannot use or update cache, disable, or force-complain via stdin * Verify that dbus mediation occurs under the Ubuntu 3.11.0-12-generic kernel: $ echo "profile nodbus { file, }" | sudo apparmor_parser -rq $ dbus-send --print-reply --system --dest=org.freedesktop.DBus /org/freedesktop/DBus org.freedesktop.DBus.ListNames | head method return sender=org.freedesktop.DBus -> dest=:1.51 reply_serial=2 array [ string "org.freedesktop.DBus" ... $ aa-exec -p nodbus -- dbus-send --print-reply --system --dest=org.freedesktop.DBus /org/freedesktop/DBus org.freedesktop.DBus.ListNames Failed to open connection to "system" message bus: An AppArmor policy prevents this sender from sending this message to this recipient, 0 matched rules; type="method_call", sender="(null)" (inactive) interface="org.freedesktop.DBus" member="Hello" error name="(unset)" requested_reply="0" destination="org.freedesktop.DBus" (bus) [Regression Potential] * The regression potential is minor because the fix is small and easy to test [Original Bug Report] Note that apparmor_parser warns that the dbus rule(s) will not be enforced and then loads the binary policy without any dbus rules. Lubuntu 13.10 installed from daily image have wifi not working, even with BT disabled. confirmed by stuw on IRC at Sun Sep 22 15:40 < stuw> iz1glg, I saw similar problem, but I don't know the reason and solution.
