This occurred if the SSH server closed the connection for any reason (in practice usually a timeout, but reproducible more easily by manually killing a test server process) while the user was in the middle of any kind of interactive prompt-based login in the GUI PuTTY terminal (be it simple password, k-i, private key passphrase, whatever). The problem was that term->userpass_state wasn't cleaned up when the connection died, and then if you started a fresh SSH session in the same terminal, the attempt to create a new term->userpass_state would find there was one already there. The simplest place to insert the missing cleanup is the call to term_provide_backend(), because that's a terminal API function which is already called to notify the terminal that one backend has gone away and the next one has turned up. (In fact, it's called twice, once to set term->backend to NULL when the first session closes, and again when the session is restarted. I see no harm in making the cleanup unconditional, not bothering to tell the difference between the two cases.) |
