+From: Jacek Bukarewicz <j.bukarewicz@samsung.com>
+Date: Thu, 27 Nov 2014 18:11:05 +0100
+Subject: [PATCH 1/8] Integration of Cynara asynchronous security checks
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This commit introduces basic framework for asynchronous policy
+checks and Cynara integration code. Functions for checking security
+policy can now return third value - BUS_RESULT_LATER denoting check
+result unavailability. Whenever policy checker cannot decide on the
+result of the check it is supposed to allocate DeferredMessage structure
+that will be passed to the upper layers which can decide what should be
+done in such situation.
+Proper handling of such case will be implemented in subsequent commits.
+Currently such return value results in message denial.
+
+Cherry picked from 4dcfb02f17247ff9de966b62182cd2e08f301238

+From: Jacek Bukarewicz <j.bukarewicz@samsung.com>
+Date: Fri, 28 Nov 2014 12:07:39 +0100
+Subject: [PATCH 2/8] Disable message dispatching when send rule result is not
+ known
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When unicast message is sent to addressed recipient and policy result
+is not available message dispatch from the sender is disabled.
+This also means that any further messages from the given connection are
+put into the incoming queue without being processed. If response is received
+message dispatching is resumed. This time answer is attached to the message
+which is now processed synchronously.
+Receive rule result unavailability is not yet handled - such messages are

+Subject: [PATCH 3/8] Handle unavailability of policy results for broadcasts
+ and receive rules
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When message is sent to the addressed recipient and receive rule
+result is unavailable we don't want to block the sender
+as it most likely will be the privileged service, so instead we queue
+it at the recipient. Any further messages sent to it will be queued to
+maintain message order. Once the answer from Cynara arrives messages are
+dispatched from the recipient queue. In such case full dispatch is
+performed - messages are sent to addressed recipient and other
+interested connections.
+Messages sent to non-addressed recipients (eavesdroppers or broadcast
+message recipients) are handled in a similar way. The difference is
+that it is not full dispatch meaning message is sent to a single recipient.
+

+Subject: [PATCH 4/8] Add own rule result unavailability handling
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Own rule result unavailability is handled like send rules - dispatching
+messages from the sender is blocked and resumed when result becomes
+available.
+
+Handler of "RequestName" method needs to return BUS_RESULT_LATER when
+policy result is not known therefore its return type is modified.
+Since bus message handlers are put into function pointer array other
+message handler function singatures are also affected.
+
+Cherry-picked from 35ef89cd6777ea2430077fc621d21bd01df92349 by Jose.bollo
+
+Updated for dbus 1.10.20 by Scott Murray and José Bollo

+Subject: [PATCH 5/8] Perform Cynara runtime policy checks by default
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This change introduces http://tizen.org/privilege/internal/dbus privilege
+which is supposed to be available only to trusted system resources.
+Checks for this privilege are used in place of certain allow rules to
+make security policy more strict.
+
+For system bus sending and receiving signals now requires
+http://tizen.org/privilege/internal/dbus privilege. Requesting name
+ownership and sending methods is still denied by default.
+
+For session bus http://tizen.org/privilege/internal/dbus privilege
+is now required for requesting name, calling methods, sending and receiving
+signals.
+
+Services are supposed to override these default settings to implement their
+own security policy.
+

-Subject: [PATCH] Adapt rules to AGL
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-AGL distribution uses the repository https://github.com/01org/meta-intel-iot-security.git
-as basis for the integration of security framework. The security framework
-that it provides is an evolution of the security framework of tizen refited
-to the distribution Ostro of Intel. This refit took the decision to simplify
-the model by removing the running label "User". More can be viewed here:
-https://github.com/01org/meta-intel-iot-security/pull/116
-
-This commits adapt the template to the rules that are now needed
-after this evolution.
-
-It also integrates one other evolutions: the shared label becomes User::App-Shared instead
-of User::App::Shared to avoid collision with application of id "Shared".
