.No crash is expected when using the Ceph messenger instance during disconnection
A Ceph messenger instance maintains an internal registry of connections that can be accessed from multiple threads. These multi-threaded accesses require proper synchronization.
Previously, when a connection was being unregistered, for example, disconnected, unsynchronized access would happen to result in the crash of the messenger’s user, such as a Ceph OSD daemon.
This release implements proper synchronization at the unregister stage and therefore, no crashes are expected.
