| message |
Make klist_invalidate() more careful and general. Acquire knotes before changing them, to synchronize with kqueue_register() and kqueue_scan(). Detach the knotes from the original knote list, change the filterops to one that always indicates EOF condition, and activate in one-shot mode. The detaching allows the original knote list head to be deleted after klist_invalidate() returns. The knotes are activated to make the EOF condition visible to the event subscribers as soon as possible. As the knotes are detached from the list, klist_invalidate() does not have to wait for userspace to process them. The use of the special filterops minimizes the need to handle klist invalidation in actual implementations of filterops. Tested by Greg Steuck OK mpi@ |

| message |
Invalidate knote list of uhid(4) after device detach. This prevents a crash that can happen if a uhid(4) device is detached while kqueue still holds references to knotes that point to the device. The invalidation has to be done after vdevgone(). This order ensures that the file descriptors return an error or EOF when kevent(2) returns the EOF events.
