Stefan Kalkowski eeb2d95b1f block: prevent from dereferencing invalid pointers ... Until now, block drivers had to deal with a pointer to the client session component, e.g.: to acknowledge block packets already processed. When a session was closed, the driver object wasn't informed explicitly, which leads to defensive programming, or lastly to a race-condition in test-blk-srv. To prevent from this class of errors, the pointer is now private to the generic block driver base class, and not accessible to the concrete driver implementation. Moreover, the driver gets explicitly informed when a session got invalidated. Ref #113		2014-02-25 14:58:02 +01:00
