This is working towards allowing the subsidiary SSH connection in an SshProxy to share the main user-facing Seat, so as to be able to pass through interactive prompts. This is more difficult than the similar change with LogPolicy, because Seats are stateful. In particular, the trust-sigil status will need to be controlled by the SshProxy until it's ready to pass over control to the main SSH (or whatever) connection. To make this work, I've introduced a thing called a TempSeat, which is (yet) another Seat implementation. When a backend hands its Seat to new_connection(), it does it in a way that allows new_connection() to borrow it completely, and replace it in the main backend structure with a TempSeat, which acts as a temporary placeholder. If the main backend tries to do things like changing trust status or sending output, the TempSeat will buffer them; later on, when the connection is established, TempSeat will replay the changes into the real Seat. So, in each backend, I've made the following changes: - pass &foo->seat to new_connection, which may overwrite it with a TempSeat. - if it has done so (which we can tell via the is_tempseat() query function), then we have to free the TempSeat and reinstate our main Seat. The signal that we can do so is the PLUGLOG_CONNECT_SUCCESS notification, which indicates that SshProxy has finished all its connection setup work. - we also have to remember to free the TempSeat if our backend is disposed of without that having happened (e.g. because the connection _doesn't_ succeed). - in backends which have no local auth phase to worry about, ensure we don't call seat_set_trust_status on the main Seat _before_ it gets potentially replaced with a TempSeat. Moved some calls of seat_set_trust_status to just after new_connection(), so that now the initial trust status setup will go into the TempSeat (if appropriate) and be buffered until that seat is relinquished. In all other uses of new_connection, where we don't have a Seat available at all, we just pass NULL. This is NFC, because neither new_connection() nor any of its delegates will _actually_ do this replacement yet. We're just setting up the framework to enable it to do so in the next commit. |
