If we hit depth 6, we would start exchanging announcement signatures.
However, we should still send a temporary update while waiting for the
reply; make the logic clear in this case that we should always send
one or the other.

The condition in send_channel_update is wrong: it needs to match the
conditions under which we send announcements.

@cdecker points out that in test_forward, where we manually create a route,
we get an error back which contains an update for an unknown channel.
We should still note this, but it's not an error for testing.

This is something which generally shouldn't happen, but we didn't
notice it previously.
We ignore this warning in the case where a channel was deleted: this
happens because one side can send an update while the other notices
that the channel is closed.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Note: this will break the gossip_store if they have current channels,
but it will fail to parse and be discarded.
Have local_add_channel do just that: the update is logically separate
and can be sent separately.
This removes the ugly 'bool add_to_store' flag.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We always call:
send_temporary_announcement(peer);
send_announcement_signatures(peer);
We should handle these in one place, since the conditional at the top
of them actually makes sure only one is effective. We also make the
caller set the peer->have_sigs[LOCAL] flag, instead of doing it
inside send_announcement_signatures().
We were sending announcements at the wrong time (on restart) somtimes.
We also move announce_channel() into the same logic, so it's always
together.

Just have a "new depth" callback, and let channeld do the right thing.
This makes the channeld paths a bit more straightforward.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Some paths (eg reconnect) were unconditionally sending a channel_update.
valgrind wasn't catching it because we unmarshal short_channel_ids[LOCAL]
as all-zeroes, so it's technically "initialized".
Create a wrapper to do this, and change the 'bool disabled' flag to be
the explicit disable flag value for clarity.

Setting these options could fail the `pytest` target if `pytest-test-groups` is

Tor wasn't actually working for me to connect to anything, but it worked
for 'ssh -D' testing.
Note that the resulting 'netaddr' is a bit weird, but I guess it's honest.

Good for debugging (you have to send SIGUSR1 to lightning_gossipd to turn
it on though, and --log-level=io on the lightningd cmdline to have it
output IO messages by default).
I also noticed that io_tor_connect_after_req_host() does a useless
test on reach->buffer[0] after it's *written*: remove it.

Use a wireaddr_internal directly (which is what we want).
Also, don't hardcode 9735, use DEFAULT_PORT internally in
seed_resolve_addr().
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This is useful for the next patch, where we want to hand the unresolved
name through to the proxy.
This also addresses @Saibato's worry that we still called getaddrinfo()
(with the AI_NUMERICHOST option) even if we didn't want a lookup.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Not all of them, but it's really about using the SOCKS proxy rather than
really using Tor at this level.

We assert() that it's set by one of the branches (it should be!) but
if we don't hit one it's uninitialized, not NULL.

1. If we have a channel_announcement, the channel is public, otherwise
it's not. Not all channels are public, as they can be local: those
have a NULL channel_announcement.
2. If we don't have a channel_update, we know nothing about that half
of the channel, and no other fields are valid.
3. We can tell if a half channel is disabled by the flags field directly.
Note that we never send halfchannels without an update over
gossip_getchannels_reply so that marshalling/unmarshalling can be
vastly simplified.

Make the update/announce messages own the element in the broadcast map
not the other way around.
Then we keep a pointer to the message, and when we free it
(eg. channel closed, update replaces it), it gets freed from the
broadcast map automatically.
The result is much nicer!
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Basically, if we don't have an announcement for the channel, stash it,
and once we get an announcement, replay if necessary.

Currently the Tor port for autotor is always 9735; the --port option
is deprecated, though we could append an optional '[@portnum]' to
'autotor' if people want it.

This means it will effect connect commands too (though it's too
late to stop DNS lookups caused by commandline options).
We also warn that this is one case where we allow forcing through Tor
without a proxy set: it just means all connections will fail.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This takes the Tor service address in the same option, rather than using
a separate one. Gossipd now digests this like any other type.

For the moment, this is a straight handing of current parameters through
from master to the gossip daemon. Next we'll change that.

Currently it's always for messages to peer: make that status_peer_io and
add a new status_io for other IO.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Risks leakage. We could do lookup via the proxy, but that's a TODO.
There's only one occurance of getaddrinfo (and no gethostbyname), so
we add a flag to the callers.
Note: the use of --always-use-proxy suppresses *all* DNS lookups, even
those from connect commands and the command line.
FIXME: An implicit setting of use_proxy_always is done in gossipd if it
determines that we are announcing nothing but Tor addresses, but that
does *not* suppress 'connect'.
This is fixed in a later patch.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
1. Only force proxy use if we don't announce any non-TOR address.
There's no option to turn it off, so this makes more sense.
2. Don't assume we want an IPv4 socket to reach proxy, use the family
from the struct addrinfo.
