Views use two types of reference counting - regular and weak, and when there are no more regular references, the view_flushanddetach() function destroys or detaches some parts of the view, including 'view->zonetable', while other parts are freed by destroy() when the last weak reference is detached. Since catalog zones use weak references to attach a view, it's currently possible that during shutdown catalog zone processing will try to add a new zone into an otherwise unused view (because it's shutting down) which doesn't have an attached zonetable any more. This could cause an assertion failure. Fix this issue by modifying the dns_view_addzone() function to expect that 'view->zonetable' can be NULL, and in that case just return ISC_R_SHUTTINGDOWN. |
