In this commit, we fix an existing bug in the NewBreachRetribution
method. Rather than creating the slice to the proper length, we instead
now create it to the proper _capacity_. As we'll now properly filter out
any dust HTLCs, before this commit, even if no HTLCs were added, then
the slice would still have a full length, meaning callers could actually
interact with _blank_ HtlcRetribution structs.
The fix is simple: create the slice with the proper capacity, and append
to the end of it.
In this commit, we fix an existing within lnd. Before this commit,
within NewBreachRetribution the order of the keys when generating the
sender HTLC script was incorrect. As in this case, the remote party is
the sender, their key should be first. However, the order was swapped,
meaning that at breach time, our transaction would be rejected as it had
the incorrect witness script.
The fix is simple: swap the ordering of the keys. After this commit, the
test extension added in the prior commit now passes.
In this commit, we extend the testRevokedCloseRetributionRemoteHodl so
that the final broadcast revoked transaction has incoming *and* outgoing
HTLC's. As is, this test fails as there's a lingering bug in the way we
generate htlc resolutions. A follow up commit will remedy this issue.
In this commit we add a new error: InvalidHtlcSigError. This error will
be returned when we're unable to validate an HTLC signature sent by the
remote party. This will allow other nodes to more easily debug _why_ the
signature was rejected.
In this commit, we fix a slight bug in lnd. Before this commit, we would
send the error to the remote peer, but in an async manner. As a result,
it was possible for the connections to be closed _before_ the error
actually reached the remote party. The fix is simple: wait for the error
to be returned when sending the message. This ensures that the error
reaches the remote party before we kill the connection.
In this commit, add a new argument to the SendMessage method to allow
callers to request that the method block until the message has been sent
on the socket to the remote peer.
This commit changes the chainntnfs tests to adhere to the new
RegisterSpendNtfn signature. It also makes sure that for the test
testSpendNotification, we are only getting notified when a spend is
mined, as previously btcd would notify on mempool inclusion, while
neutrino and bitcoind would notify only on confirmation, and the test
wouldn't catch this.
This commit adds a boolean to RegisterSpendNtfn, giving the caller the
option to only register for notifications on confirmed spends. This is
implemented for the btcd backend using logic similar to what is in used
for Neutrino, paving the way for later unifying them.
In this commit, we fix an issue where users would be displayed negative
amounts of satoshis either as sent or received. This can happen if the
total amount of channel updates decreases due to channels being closed.
To fix this, we properly handle a negative difference of channel
updates by updating the stats logged to only include active
channels/links to the switch.
In this commit, we modify the docs in order to clarify that both btcd
and bitcoind are supported as chain backends. Many users expressed
confusion as the old set of docs stated that we "require" my btcd fork,
rather than clarifying that *if* you want to use btcd, then you must use
my fork.
In this commit we add a new command line option (and a sane default) to
allow users to specify the *smallest* inbound channel that they'll
accept. Having a higher-ish limit lets users limit their channels, and
also avoid a series of very low value "spam" channels.
The new option is --minchansize, and expressed in satoshis. If we
receive an inbound channel request for a value smaller than this, then
we'll immediately reject it.
In this commit, we fix a minor logging bug introduced in a prior commit.
Before we would directly modify the *net.TCPAddr that was a part of the
brontide connection. This achieved our goal, but would print weird log
messages as we mutated the port in the already established connection.
In this commit, we fix that by ensuring we create a copy iff it's a
net.TCPAddr, then modify that and replace the instance in the
lnwire.NetAddress.
Fixes#991.
In this commit, we relax the constraints on accepting an exit hop
payment a bit. We'll now accept any incoming payment that _at least_
pays the invoice amount. This puts us further inline with the
specification, which recommends that nodes accept overpayment by a
certain margin.
Fixes#1002.
Changes in gRPC `channelbalance` service response message
of adding `pending_open_balance` parameter with sum of
channels open pending balances denominated in satoshis
lnd can't detect bitcoind configuration if the config file has spaces around the = character, e.g.:
```
zmqpubrawblock = tcp://127.0.0.1:28332
zmqpubrawtx = tcp://127.0.0.1:28332
rpcuser = rpcuser
```
I had to dig into the source code to understand what was wrong.
This patch solves this problem, bitcoind's config parsing source code can be seen at https://github.com/bitcoin/bitcoin/blob/master/src/util.cpp
