First, how we record "our_funds" and then apply pushes vs lease_fees
(for liquidity ad buys/sales) was exactly opposite.
For pushes we were reporting the total funded into the channel, with the
push representing how much we'd later moved to the peer.
For lease_fees we were rerporting the total in the channel, with the
push representing how much was already moved to the peer.
We fix this (from a view perspective) by re-adding lease fees to what's
reported in the channel funding totals. Since this is now new behavior
(for leased channel values), we added new fields so we can take the old
field names thru a deprecation cycle.
We also make it possible to differentiate btw a push and a lease_fee
(before they were all the same), by adding to new fields to `listpeers`:
`fee_paid_msat` and `fee_rcvd_msat`.
This allows us to avoid math in the bookkeeper, instead we just pick
the numbers out directly and record them.
Fixes#5472
Changelog-Added: JSON-RPC: `listpeers` now has a few new fields for `funding` (`remote_funds_msat`, `local_funds_msat`, `fee_paid_msat`, `fee_rcvd_msat`).

9cad7d6a6a changed the behavior of `channel_active`, which slightly
broke how our balance snapshots work (we need info about channels that
aren't on-chain yet).
This patches adds AWAITING_UNILATERAL back in.
We used to tell connectd to remember our connect delay, and hand it
back (increased if necessary).
Instead, simply record when we last tried to connect. If it was less
than 10 minutes ago, double delay (up to 5 minutes max), otherwise
reset delay to 1 second.
This covers all scenarios: whether we reconnect then immediately
disconnect, or never successfully connect, it doesn't matter.

We need a record of the channel account before you start sending
payments through it. Normally we don't start allowing payments to be
sent until after the channel has locked in but zeroconf does away with
this assumption.
Instead we push out a "channel_proposed" event, which should only show
up for zeroconfs.
If we expect further events for an onchain output (because we can steal
it away from the 'external'/rightful owner), we mark them.
This prevents us from marking a channel as 'onchain-resolved' before
all events that we're interested in have actually hit the chain.
Case that this matters:
Peer publishes a (cheating) unilateral close and a timeout htlc (which
we can steal).
We then steal the timeout htlc.
W/o the stealable flag, we'd have marked the channel as resolved when
the peer published the timeout htlc, which is incorrect as we're still
waiting for the resolution of that timeout htlc (b/c we *can* steal it).
it's nice to know what node your channel was opened with. in theory we
could use listpeers to merge the data after the fact, except that
channels disappear after they've been closed for a bit. it's better to
just save the info.
we print it out in `listbalances`, as that's a great place account level
information
We don't push out a coin_move for a channel open until it's locked in,
but this causes problems for channels that close before they're locked.
So if we go the "close before locked in" route, we push out a channel
open event.
These will get a blockheight of 0, if we haven't seen the
funding transaction in a block yet.

The only places which should call try_reconnect now are the "connect"
command, and the disconnect path when it decides there's still an
active channel.
This introduces one subtlety: if we disconnect when there's no active
channel, but then the subd makes one, we have to catch that case!
This temporarily reverts "slow" reconnections to fast ones: see next
patch.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Connectd already does this when we *receive* an error or warning, but
now do it on send. This causes some slight behavior change: we don't
disconnect when we close a channel, for example (our behaviour here
has been inconsistent across versions, depending on the code).
When connectd is told to disconnect, it now does so immediately, and
doesn't wait for subds to drain etc. That simplifies the manual
disconnect case, which now cleans up as it would from any other
disconnection when connectd says it's disconnected.

Give them time to process any final messages! If there's a reconnect,
then we need to clean them up immediately of course.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This allows us to detect when lightningd hasn't seen our latest
disconnect/reconnect; in particular, we would hit the following pattern:
1. lightningd says to connect a subd.
2. connectd disconnects and reconnects.
3. connectd reads message, connects subd.
4. lightningd reads disconnect and reconnect, sends msg to connect to subd again.
5. connectd asserts because subd is alreacy connected.
This way connectd can tell if lightningd is talking about the previous
connection, and ignoere it.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Before this patch:
1. connectd says it's connected (peer_connected)
2. we tell connectd we want to talk about each channel (peer_make_active)
3. connectd gives us an fd for each channel, and we connect it to a subd (peer_active)
4. OR, connectd says it sent something about a channel we didn't tell it about, with an fd (peer_active)
Now:
1. connectd says it's connected (peer_connected)
2. we start all appropriate subds and tell connectd to what channels/fds (peer_connect_subd).
3. if connectd says it sent something about a channel we didn't tell it about, we either tell
it to hang up (peer_final_msg), or connect a new opening daemon (peer_connect_subd).
This is the minimal-size patch, which is why we create socket pairs in
so many places to use the existing functions. Many cleanups are
possible, since the new flow is so simple.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
First, connectd tells us the peer has connected, and we call the connected hook,
and if it says it's fine, we are actually connected and we fire off notifications.
Of course, we could be disconnected while in the connected hook, and that would
mean we tell people about a connection which is no longer current.
Make this clear with a tristate: if we're not marked disconnected by
the time the hooks finish, we're good. It also gives us a cleaner
"connect" command return when we connected but disconnected before
processing.

Previously we wouldn't notify when a channel moves into state
"CHANNELD_AWAITING_LOCKIN", as this is the original state (so there's
no movement btw states). This meant that it's impossible to track when a
channel's commitment txs have been exchanged and we're waiting for
onchain confirmation.
It's useful to have notice of this initialization though, all in one
place so that the `channel_state_changed` notification can successfully
track the entire lifecycle of a channel, from inception to close.
Note that for v2 "dual-funded" channels, we already notify at the same place, at
"DUALOPEND_AWAITING_LOCKIN" (the initial state for a dualopend channel
is "DUALOPEND_OPEN_INIT" -- this is the only state we don't get notified
at now...)
Changelog-Added: Plugins: `channel_state_changed` now triggers for a v1 channel's initial "CHANNELD_AWAITING_LOCKIN" state transition (from prior state "unknown")

The extra entry in opt_table would never be called, leaving plugins
clueless why options keep defaulting.
Note that option registration outside startup does nothing.
Instead, dynamic plugins can use `plugin start [second_parameter]` to pass options.
Otherwise we hangs forever in startup when it was the last plugin, we would
miss destroy_plugin --> check_plugins_manifests --> io_break
e.g. when a plugin tries to register a bool option with a string as default value.
We noticed bogus behavior where (with 200 blocks added at once)

There are several possible causes for this:
1. We have two channels with the same rr_number. A quick audit shows we always set that rr_number to a unique value (and 64 bits, so wrap is not possible between the release and now!).
2. It's theoretically possible that sort() could compare a value with itself, but that would be really dumb: it doesn't that I've ever seen, but then, we've never seen this assert() hit, either.
3. listincoming has given us the same channel twice. I don't see how that is possible: we had a race where channels could momentarily vanish, but never be duplicated (emailed crash.log shows no duplicates!).
4. General corruption/freed memory access. If a channel we've just looked up is gone but still in the hash table, this is possible but would cause lots of random behavior and crashes.

Check funding_outnum validity first to avoid reading invalid outputs
Changelog-Fixed: Fixed a potential issue if the number of outputs decreases in a dualopen RBF or splice.
We used to agree up on the `minimum_depth` with the peer, thus when
they told us that the funding locked we'd be sure we either have a
scid or we'd trigger the state transition when we do. However if we
had a scid, and we got a funding_locked we'd trust them not to have
sent it early. Now we explicitly track the depth in the channel while
waiting for the funding to confirm.
Changelog-Fixed: channeld: Enforce our own `minimum_depth` beyond just confirming
Not only can the outgoing edge be a zeroconf channel, it can also be
the incoming channel. So we revert to the usual trick of using the
local alias if the short_channel_id isn't known yet.
We use the LOCAL alias instead of the REMOTE alias even though the
sender likely used the REMOTE alias to refer to the channel. This is
because we control the LOCAL alias, and we keep it stable during the
lifetime of the channel, whereas the REMOTE one could change or not be
there yet.
We use this in a couple of places, when we want to refer to a channel
by its `short_channel_id`, I'm moving this into a separate function
primarily to have a way to mark places where we do that.
The direction only depends on the ordering between node_ids, not the
short_channel_id, so we can include it and it won't change. This was
causing some trouble loading the `channel_hints` in the `pay` plugin.
We don't trigger on depth=0 since that'd give us bogus blockheights
and pointers into the chain, instead we defer until we get a first
confirmation. This extracts some of the logic from `lockin_complete`,
into the depth change listener (not the remote funding locked since at
that point we're certainly locked in and we don't really care about
that for bookkeeping anyway).
This is needed for us to transition to CHANNELD_NORMAL for zeroconf
channels, i.e., channels where we don't have a short channel ID yet.
We'll have to call lockin_complete a second time, once we learn the
real scid.
We locally generate an update with our local alias, and get one from
the peer with the remote alias, so we need to add them both. We do so
only if using the alias in the first place though.
`alias_local` is generated locally and sent to the peer so it knows
what we're calling the channel, while `alias_remote` is received by
the peer so we know what to include in routehints when generating
invoices.
This is the counterpart of the `mindepth` parameter in `fundchannel`
and friends. Allows dynamic lookups of `node_id` and selectively
opting into `option_zeroconf` being used.
Changelog-Added: plugin: The `openchannel` hook may return a `mindepth` indicating how many confirmations are required.
This will eventually enable us to specify 0 for zeroconf channels.
Changelog-Added: JSON-RPC: Added `mindepth` argument to specify the number of confirmations we require for `fundchannel` and `multifundchannel`

Get it to log direct to stdout, so we see what's happening *as it
happens* rather than as we read it. We could restore the thread we
were using before, but that added more problems than it solved.
This means that we need the hsm password prompts in the log though.

1. We set an outgoing htlc's `failonion` when we get a commitment_signed.
2. We don't transfer it to the corresponding incoming HTLC until we send
commitment_signed and receive revoke_and_ack (meaning, outgoing htlc is
completely dead).
3. If between these steps we go onchain, onchaind (after 3 blocks) tells us
to fail the HTLC.
4. hout->failonion is set, but hout->hin has not been failed yet. We
do a sanity check and print a nasty message, and fail it with
WIRE_PERMANENT_CHANNEL_FAILURE instead of relaying the error.
So handle this case explicitly.

This is being hit: it's possible if connectd and lightningd get desynchronized,
and we'll handle this later when peer is activated.

We should be using amount_msat always. Many tests were not. Plus,
deprecating it simplifies the code.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Deprecated: JSONRPC: `sendpay` `route` elements `msatoshi` (use `amount_msat`)
This is consistent with our output changes, and increases consistency.
It also keeps future sanity checks happy, that we only use JSON msat
helpers with '_msat' fields.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: JSON-RPC: `invoice`, `sendonion`, `sendpay`, `pay`, `keysend`, `fetchinvoice`, `sendinvoice`: `msatoshi` argument is now called `amount_msat` to match other fields.
Changelog-Deprecated: JSON-RPC: `invoice`, `sendonion`, `sendpay`, `pay`, `keysend`, `fetchinvoice`, `sendinvoice` `msatoshi` (use `amount_msat`)
The new msat fields are turned into Millisatoshi, so handle that correctly
too in tests too.

Changelog-Deprecated: Plugins: `coin_movement` notification: `balance`, `credit`, `debit` and `fees` (use `balance_msat`, `credit_msat`, `debit_msat` and `fees_msat`)
In general, we don't like to use `null` in JSON: simply omit the
field. I found this one because it broke our 'msat' parsing (made
stricter in followup) which doesn't allow `null`.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Deprecated: `listconfigs` `plugins` `options` which are not set are omitted, not `null`.
We had json_add_amount_msat_only(), which was designed to be used to
print out msat fields, if we had sats.
However, we misused it, so split it into the three different cases:
1. json_add_amount_sat_msat: We are using it correctly, with a field called
xxx_msat.
2. json_add_amount_sats_deprecated: We were using it wrong, so deprecate
the old field and create a new one which does end in _msat.
3. json_add_sats: we were using it to hand sats as a JSON parameter to an
interface, where "XXXsat".

Changelog-Deprecated: Plugins: `rbf_channel` and `openchannel2` hooks `their_funding` (use `their_funding_msat`)

Changelog-Deprecated: Plugins: `channel_opened` notification `amount` (use `funding_msat`)
Changelog-Deprecated: JSON-RPC: `listtransactions` `msat` (use `amount_msat`)
Changelog-Deprecated: Plugins: `htlc_accepted` `forward_amount` (use `forward_msat`)
Changelog-Added: Plugins: `htlc_accepted` now exposes the `short_channel_id` for the channel from which that HTLC is coming from and the low-level per-channel HTLC `id`, which are necessary for bridging two different Lightning Networks when MPP is involved.
When starting a plugin, if the plugin path cannot be found in
absolute context, assume it is a relative path to the default
plugins dir. As a result, the following now works when my_plugin.py
is installed in the default plugins dir:
lightning-cli plugin start my_plugin.py
Also update the plugin documentation to reflect that the use of a
relative path is now available.
Changelog-Added: plugin start RPC subcommand now assumes relative path to default plugins dir if the path is not found in absolute context. i.e. lightning-cli plugin start my_plugin.py

We call out to connectd to activate the peer, and while we do that,
channel->owner is NULL. A better pattern would be to set up the unsaved
channel once connectd has given us the peer, but this works for now.

This seems to prevent broad propagation, due to LND not allowing it. See
https://github.com/lightningnetwork/lnd/issues/6432
We still announce it if you disable deprecated-apis, so tests still work,
and hopefully we can enable it in future.
Fixes: #5196

Changelog-EXPERIMENTAL: Protocol: disabled websocket announcement due to LND propagation issues
Mostly comments and docs: some places are actually paths, which
I have avoided changing. We may migrate them slowly, particularly
when they're user-visible.

This adds config and commandline options for htlc_min_msat, htlc_max_msat and
announce_discovered_ip. The default is 0msat for htlc_min_msat, unlimited for
htlc_max_msat and enabled for announce_discovered_ip.
The announce_discovered_ip gets the disable commandline switch --disable-ip-discovery
Changelog-added: Config options for htlc_min_msat, htlc_max_msat and announce_discovered_ip.
Makes types harder, and I've never personally used them.
Changelog-Deprecated: JSON-RPC: `invoice` `expiry` no longer allowed to be a string with suffix, use an integer number of seconds.
