-Subject: [PATCH 4/8] Integration of Cynara asynchronous security checks
-
-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.

-Subject: [PATCH 5/8] Disable message dispatching when send rule result is not
- known
-
-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
-rejected. Also, if message is sent to non-addressed recipient and policy result
-is unknown, message is silently dropped.

-Subject: [PATCH 6/8] Handle unavailability of policy results for broadcasts
- and receive rules
-
-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 7/8] Add own rule result unavailability handling
-
-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.
-
-Change-Id: I4c2cbd4585e41fccd8a30f825a8f0d342ab56755

-
-This method is used to obtain smack label of given D-Bus client.
-Note that it is deprecated and is included only for compatilibity with
-existing D-Bus users. GetConnectionCredentials should be used to obtain
-client's credentials.

-Subject: [PATCH] Perform Cynara runtime policy checks by default
-
-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.
