+Subject: [PATCH] media: untangle MediaRouterUI lifetimes
+
+Currently, MediaRouterUI is owned by MediaItemUIDeviceSelectorView.
+There is an observer method named "OnControllerInvalidated" which
+MediaItemUIDeviceSelectorView reacts to by deleting the MediaRouterUI it
+owns. However, OnControllerInvalidated can actually be called in two
+different situations:
+
+* From MediaRouterUI::TakeMediaRouteStarter(), in which case the
+  MediaRouterUI object is *not* being destroyed, but should be, because
+  it can't be safely used after TakeMediaRouteStarter() ends;
+* From MediaRouterUI::~MediaRouterUI(), in which case the MediaRouterUI
+  object *is* being destroyed already and should not be.
+
+In the second case, only the fact that libc++ nulls out unique_ptr
+before destroying the pointed-to object saves us from a use-after-free;
+under libstdc++, we UaF immediately by re-entering the destructor. Even
+under libc++ though this is still very dangerous, because any observers
+that happened to be registered after MediaItemUIDeviceSelectorView will
+be invoked after the destruction of the object they're observing. Right
+now there are no such other observers, but the fact remains that this
+interface is basically a UaF timebomb.
+
+This change separates "this object is about to be destroyed" (an
+observable state) from "please destroy this object, it is no longer
+useful" (a callback that is made to the object's owner) by:
+
+1. Renaming OnControllerInvalidated to OnControllerDestroying, to make
+   it very clear what is happening to the object, and
+2. Adding a RegisterDestructor method to CastDialogController, which
+   allows MediaItemUIDeviceSelectorView to pass a callback into
+   MediaRouterUI which MediaRouterUI can use to arrange for its own
+   destruction.
+
+This is still a bit tangled and ungainly, but it's safe. A fuller
+writeup is on the linked bug.
+
