I just had a quick fly over the patches so far. Shouldn't there be some kind of constraint for an automatic reconnection feature after a crash to prevent this being exploited by ROP brute force attacks? E.g. adding some (maybe continuously increasing) delay and/or limiting the amount of reconnects within a certain time frame would come to my mind. Best regards, Christian Schoenebeck
