| Summary | 0004630: cadet connect fails persistently if port not open before other peer tries to connect | ||||
| Description | If, as is for example the case in the set test cases, a CADET port is only opened *after* another peer tried to connect to the port, the connection fails for good (unless the other peer fully retries to create the channel). Instead, 1) the receiving peer should remember incoming channels to closed ports (for a short time T?), in case this is just an issue introduced by the other peer being very fast; 2) alternatively/additionally, the initiating peer should retry the 'syn' after timeout "T". We can skip (2) if the incoming peer remembers 'forever', but that's awkward as it ties down resources 'forever' based on 1 packet. I understand (2) may be an issue if reliability is implemented at a lower layer; however, I'd in fact expect (2) to happen right now, as the peer with the closed port should simply not ACK that he got the SYN, right? (IIRC we said that for CADET we don't send RST or ACK if we get a SYN for a closed port, right?) | ||||
