+ * @page page_ext_session_lock_v1 The ext_session_lock_v1 protocol
+ * secure session locking with arbitrary graphics
+ *
+ * @section page_desc_ext_session_lock_v1 Description
+ *
+ * This protocol allows for a privileged Wayland client to lock the session
+ * and display arbitrary graphics while the session is locked.
+ *
+ * The compositor may choose to restrict this protocol to a special client
+ * launched by the compositor itself or expose it to all privileged clients,
+ * this is compositor policy.
+ *
+ * The client is responsible for performing authentication and informing the
+ * compositor when the session should be unlocked. If the client dies while
+ * the session is locked the session remains locked, possibly permanently
+ * depending on compositor policy.
+ *
+ * The key words "must", "must not", "required", "shall", "shall not",
+ * "should", "should not", "recommended", "may", and "optional" in this
+ * document are to be interpreted as described in IETF RFC 2119.
+ *
+ * Warning! The protocol described in this file is currently in the
+ * testing phase. Backward compatible changes may be added together with
+ * the corresponding interface version bump. Backward incompatible changes
+ * can only be done by creating a new major version of the extension.
+ *

+ *
+ * The only surfaces that should be rendered while the session is locked
+ * are the lock surfaces created through this interface and optionally,
+ * at the compositor's discretion, special privileged surfaces such as
+ * input methods or portions of desktop shell UIs.
+ *
+ * The locked event must not be sent until a new "locked" frame (either
+ * from a session lock surface or the compositor blanking the output) has
+ * been presented on all outputs and no security sensitive normal/unlocked
+ * content is possibly visible.
+ *
+ * The finished event should be sent immediately on creation of this
+ * object if the compositor decides that the locked event will not be sent.
+ *
+ * The compositor may wait for the client to create and render session lock
+ * surfaces before sending the locked event to avoid displaying intermediate
+ * blank frames. However, it must impose a reasonable time limit if
+ * waiting and send the locked event as soon as the hard requirements
+ * described above can be met if the time limit expires. Clients should
+ * immediately create lock surfaces for all outputs on creation of this
+ * object to make this possible.
+ *
+ * This behavior of the locked event is required in order to prevent
+ * possible race conditions with clients that wish to suspend the system
+ * or similar after locking the session. Without these semantics, clients
+ * triggering a suspend after receiving the locked event would race with
+ * the first "locked" frame being presented and normal/unlocked frames
+ * might be briefly visible as the system is resumed if the suspend
+ * operation wins the race.
+ *
+ * If the client dies while the session is locked, the compositor must not
+ * unlock the session in response. It is acceptable for the session to be
+ * permanently locked if this happens. The compositor may choose to continue
+ * to display the lock surfaces the client had mapped before it died or

+ *
+ * Compositors may also allow a secure way to recover the session, the

+ * When a configure event is received, if a client commits the surface
+ * in response to the configure event, then the client must make an
+ * ack_configure request sometime before the commit request, passing
+ * along the serial of the configure event.
+ *
+ * If the client receives multiple configure events before it can
+ * respond to one, it only has to ack the last configure event.
+ *
+ * A client is not required to commit immediately after sending an
+ * ack_configure request - it may even ack_configure several times
+ * before its next surface commit.
+ *
+ * A client may send multiple ack_configure requests before committing,
+ * but only the last request sent before a commit indicates which
+ * configure event the client really is responding to.
+ *
+ * Sending an ack_configure request consumes the configure event
+ * referenced by the given serial, as well as all older configure events
+ * sent on this object.
+ *
+ * It is a protocol error to issue multiple ack_configure requests
+ * referencing the same configure event or to issue an ack_configure
+ * request referencing a configure event older than the last configure
+ * event acked for a given lock surface.
