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.
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
Alters the behavior of ConnectEnsure to initiate a connection
attempt in both directions. Additionally, the wait predicate only
returns true after cross checking both peer lists.
This commits changes the behavior of our connection
reestablishment, and resolves some minor issues that
could lead to uncancelled requests or an infinite
connection loop.
- Will not attempt to Remove connection requests with
an ID of 0. This can happen for reconnect attempts
that get scheduled, but have not started at the
time the server cancels the connection requests.
- Adds a per-peer cancellation channel, that is
closed upon a successful inbound or outbound
connection. The goroutine spwaned to handle the
reconnect by the peerTerminationWatch now
selects on this channel, and skips reconnecting
if it is closed before the backoff matures.
- Properly computes the backoff when no entry in
persistentPeersBackoff is found. Previously, a
value of 0 would be returned, cause all subsequent
backoff attempts to use a backoff of 0.
- Cancels a peers retries and remove connections
immediately after receiving an inbound connection,
to mimic the structure of OutboundPeerConnected.
- Cancels all persistent connection requests after
calling DisconnectPeers.
- Allow additional connection attempts to peers, even if
there already exists a pending connection attempt.
In this commit, we fix a minor bug in the prior versions of lnd. Before
this commit, if we received a new inbound connection for channel
creation, the channel was created, and then the peer disconnected, we
wouldn't automatically reconnect.
In this commit we fix this issue by overloading the WatchNewChannel
method to also accept the peer's ID so we can add it to the set of
persistent connections.
In this commit, we fix an existing bug within the codebase: if a peer
connected to us inbound, then we'd attempt to use the assigned port when
re-establishing a connection to them. We fix this issue in this commit
by adding a new method to look up any advertisements for the peer, and
use the specified port that matches our connection attempt. If we can't
find a proper advertisement, then we'll simply use the default peer
port.
In this commit, we modify the sphinx replay test to actually force close
that final channel. We do this, as otherwise, we'll now reject the co-op
close attempt as the channel still has active HTLCs.
In this commit, we follow up to the prior commit by ensuring we won't
accept a co-op close request for a chennel with active HTLCs. When
creating a chanCloser for the first time, we'll check the set of HTLC's
and reject a request (by sending a wire error) if the target channel
still as active HTLC's.
In this commit, we fix a bug that at times could cause any dangling
HTLC's to be sent to miner's fees if a user attempted to close out a
channel cooperatively that still had pending HTLC's. We'll first prevent
this at the RPC level by rejecting any attempts to trigger a co-op
channel closure while a channel still have dangling HTLC's.
In this commit, we fix a logic error in our routine for converting a
uint64 to/from base32. Before this commit, we assumed that the max
number of groups was 12. However, the math.MaxUint64 (1<<64 - 1) can
actually consume more than 12 groups with an extra set of bits. Before
this commit, we would panic when attempting to parse an invoice
generated like so:
* addinvoice --amt 1337000 --expiry 99999999999999999
To fix this issue, we modify our logic to expect at most 13 groups.
Additionally, we've added a new test that would panic before applying
this commit.
Fixes#972.
This commit mitigates a problem within the ChannelArbitrator, where
after a restart we would start up in the state StateBroadcastCommit but
fail to broadcast out commitment because a conflicting transaction (most
likely our own commitment) was already broadcast. A more complete fix
for this case will be added later, but this commit let the
ChannelArbitrator continue, trying to close out the channel.
