connectd: wean off gossip_wire message types, use our own. This involves much renaming of gossip -> channel. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
7 years ago
#include <common/cryptomsg.h>
connectd: do socket binding during initial setup. gossipd does a two-step initialization: it only tries to create the listening sockets when it&#39;s activated. This means it doesn&#39;t know the addresses to announce until this point. Now connectd is doing this, this would mean we&#39;d have to tell gossipd later (&#34;oh, BTW here are your addresses&#34;) since we need to start gossipd before connectd activation. So make connectd do all the setup, but only actually listen on the fds once we activate it. We clone the gossip_init message into connect_wire.csv. The master daemon still waits for a reply from connectd for the activate message, since it wants to be listening before it prints &#34;Server started&#34;.

connectd: new daemon to handle connections. This is just copying most of gossipd/gossip.c into connectd/connect.c. It shares the same wire format as gossipd during transition, and changes are deliberately minimal. It also has an additional message &#39;connect_reconnected&#39; which it sends to the master daemon to tell it to kill a peer; gossipd relied on closing the gossipfd to do this, but connectd doesn&#39;t maintain an fd with remote peers.

# Master -> connectd: connect to a peer.
connectctl_connect_to_peer,2001
connectctl_connect_to_peer,,id,struct pubkey
connectd: rely on the master to tell us to reconnect. connectd tells master about every disconnection, and master knows whether it&#39;s important to reconnect. Just get the master to invoke a new connect command if it considers the peer important! The only twist is timeouts: we don&#39;t want to immediately reconnect if we&#39;ve failed to connect. To solve this, connectd passes a &#39;delaytime&#39; to the master when a connection fails, and the master passes it back when it asks for a connection.

connectctl_connect_to_peer,,seconds_waited,u32
connectd: remove separate address hint message. Include it as an optional field in the connect_to_peer message (it was added before we had optional fields). The only issue is that reconnects want it too, so again connectd hands it back to master in connectctl_connect_failed. Signed-off-by: Rusty Russell &lt;rusty@rustcorp.com.au&gt;

connectd: always tell master when connection fails/succeeded. We used to separate implicit connection requests (ie. timed retries for important peers) and explicit ones, and send a WIRE_CONNECTCTL_CONNECT_TO_PEER_RESULT for the latter. In the success case, that&#39;s now redundant, since we hand the connected peer to the master using WIRE_CONNECT_PEER_CONNECTED; we just need a message for the failure case. And we might as well tell the master every failure, so we don&#39;t have to distinguish internally. This also solves a race we had before: connectd would send WIRE_CONNECTCTL_CONNECT_TO_PEER_RESULT which completes the incoming JSON connect command, then send WIRE_CONNECT_PEER_CONNECTED. So there&#39;s a window where the JSON command can return, but the peer isn&#39;t known to lightningd yet. Signed-off-by: Rusty Russell &lt;rusty@rustcorp.com.au&gt;

# master -> connectd: peer has disconnected.

connectctl_peer_disconnected,,id,struct pubkey
connectd: wire up dev_memleak. We need several notleak() annotations here: 1. The temporary structure which is handed to retry_peer_connected(). It&#39;s waiting for the master to respond to our connect_reconnected message. 2. We don&#39;t keep a pointer to the io_conn for a peer, so we need to mark those as not being a leak.
