gossip/tor.c: new file for socks proxy code. All gossipd needs from common/tor is do_we_use_tor_addr(), so move that and the rest of the tor-specific handshake code into gossip/tor.c Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> 2018-05-10 01:18:23 +02:00			`#ifndef LIGHTNING_GOSSIPD_TOR_H`

tor: clean up io_tor_connect. Instead of storing a wireaddr and converting to an addrinfo every time, just convert once (which also avoids the memory leak in the current code). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> 2018-05-10 01:18:24 +02:00			`struct addrinfo;`

gossipd: hand io_tor_connect the host as a string. Previously it converted the wireaddr to a string internally: to support unresolved names we need that done externally. We actually tell the SOCKS5 proxy to do a domain lookup already, even though we give use IP/IPv6 address, so this change is sufficient to support connect-by-name. Note replacement of assert() with an explicit case statement, which has the benefit that the compiler complains when we add new ADDR_INTERNAL types.
