This commit adds the `tlsextraip` flag to the cli to add an
ip to the generated certificate. This is usefull when using
a loadbalancer to access the node.
This commit adds the `lnnet` package which contains an
implementation of the newly created LightningNet interface which
multiplexes the Dial and DNS-related functions to use net
by default and torsvc if a flag is specified. This modularization
makes for cleaner code.
This commit adds a new interface named NetInterface and two
implementations of it: RegularNet & TorProxyNet. These two structs
are used in config.go in an attempt to clean up the code and
abstract away the dialer and DNS functions.
This commit adds a new module named 'torsvc' which houses all Tor
functionality in an attempt to isolate it and make it reusable in
other projecs. Some additional tweaks were made to config.go and
to the bootstrapper.
This commit adds Tor support. Users can set the --TorSocks flag
to specify which port Tor's SOCKS5 proxy is listening on so that
lnd can connect to it. When this flag is set, ALL traffic gets
routed over Tor including DNS traffic. Special functions for
DNS lookups were added, and since Tor doesn't natively support
SRV requests, the proxySRV function routes connects us to
a DNS server via Tor and SRV requests can be issued directly
to the DNS server.

In this commit, we add an additional constraint to the RPC
configuration parsing. Before this commit, it was possible to start lnd
with either RPC server listening on an external interface *without*
authentication disabled. After this commit, if a user tries to start
the RPC server listening on an external interface without any sort of
RPC authentication, then the daemon will fail to start up.
This commit causes the configuration parser to accept the values of
RPCUser, RPCPass, and (for the bitcoind back-end) ZMQPath configured
in lnd.conf or on the command line ONLY when all are specified. It
causes the configuration parser to look in btcd.conf or bitcoin.conf
ONLY when none are specified, and causes an error to be returned when
only some are specified, as users have done so erroneously and the
lack of clear feedback has caused difficulties.
In this commit, we add 6 new integration tests to test the various
actions that may need to be performed when either side goes on-chain to
fully resolve HTLC’s. Many of the tests are mirrors of each other as
they test sweeping/resolving HTLC’s from both commitment transactions.
This commit removes the `peerport` and `rpcport` config options and
adds `listen`, `rpclisten`, and `restlisten` options to allow setting
one or multiple interfaces to listen on for incoming connections.
It also adds a `nolisten` option to allow disabling the listener for
incoming peer connections.
This commit factors out the btcd and ltcd options into their own sections
similar to neutrino, and adds a bitcoind section as well. Now, you specify
node options similarly to:
--ltcd.rpchost=...
or
--btcd.rpcuser=...
or
--bitcoind.zmqpath=...
For Bitcoin, you specify an alternate back-end to btcd as follows:
--bitcoin.node=bitcoind
or
--bitcoin.node=neutrino
You can also specify the default option:
--bitcoin.node=btcd
For Litecoin, only `btcd` mode is valid, and corresponds to the `ltcd`
section. For example:
--litecoin.node=btcd
--ltcd.rpchost=...
The new code also attempts to read the correct options and auth info
from bitcoin.conf just as it does from btcd.conf/ltcd.conf.
This commit moves the definition of DefaultNumChanConfs into
the chainConfig (such that it is set as e.g.
"--bitcoin.defaultchanconfs"), making it possible to set
individually for different chains.
It also adds the flag DefaultRemoteDelay to the chainConfig,
which can be used to set the CSV delay we will require the remote
to wait before retrieving its own funds in case of an
uncooperative close of the channel.
Both these are set 0 by default (if not specified by the user),
which in that case we will dynamically set the values, scaling
them according to the channel size.
This commit moves the forwarding policy rules for Bitcoin
and Litecoin, previously defined in the chainregistry, to
config.go, making them possible to define by the user.
We validate that the TimeLockDelta set is at least 4, the
other rules we let the user specify arbitrarily, even 0.
In this commit, we increase the default number of confirmations we
require for funding flows from 1 to 3. The value of 1 was rather
unstable on testnet due to the frequent multi-block re-orgs.
Additionally, a value of 3 ensures our funding transaction is
sufficiently buried before we deem is usable.
Early in the lifetime of the project here were a few files we either
copied entirely, or used as the basis for code within lnd. Before this
PR, this was not recognized by retaining the original copyright. With
this commit, we remedy that by explicitly noting the copyright in the
relevant files.
Fixes#423.
Run go fmt so config file is formatted correctly. Also rename
newVertex to NewVertex in pathfind_test and notifications_test
as it is now exported from the routing package.
Add option to set trickleDelay for AuthenticatedGossiper in
command line, with default value of 300 milliseconds. Pass this
value to newServer, which uses it when creating a new instance of
AuthenticatedGossiper. Also set this value to 300 milliseconds when
creating nodes in integration tests.
In this commit we add a new option to lnd, cpuprofile. With this option
we add additional telemetry hooks into and, allowing users to generate
CPU profiling files to measure hot spots within the daemon.
This commit adds a new debug mode for lnd
called hodlhtlc. This mode instructs a node
to refrain from settling incoming HTLCs for
which it is the exit node. We plan to use
this in testing to more precisely control
the states a node can take during
execution.
This commit adds a new config option to allow callers to optionally
disable connection bootstrapping. This may be desirable for several
reasons, but primary, we add this so we can keep our integration tests
under the same context as before bootstrapping existed.
This commit modifies the way that we create the macaroon database, and
also create the initial macaroons themselves. Rather than creating a
new macaroon DB for each chain, we instead create a single instance for
all chains. Additionally, if the datadir has been modified, and the
macaroon paths haven’t been modified, the macaroons are now scoped to
those paths.
This commit adds a new command line option that allows clients to
specify a default value to use when responding to a new channel funding
request. In a future change, a pure mapping will be added, with the
command line option having higher precedence.
Support for regtest allows us to create integration tests to verify
interoperability with other implementations. This seems to work, and
allows to connect to `btcd` and indirectly to `bitcoind` so we can run
lnd on the same network as eclair and c-lightning.

The btclog package has been changed to defining its own logging
interface (rather than seelog's) and provides a default implementation
for callers to use.
There are two primary advantages to the new logger implementation.
First, all log messages are created before the call returns. Compared
to seelog, this prevents data races when mutable variables are logged.
Second, the new logger does not implement any kind of artifical rate
limiting (what seelog refers to as "adaptive logging"). Log messages
are outputted as soon as possible and the application will appear to
perform much better when watching standard output.
Because log rotation is not a feature of the btclog logging
implementation, it is handled by the main package by importing a file
rotation package that provides an io.Reader interface for creating
output to a rotating file output. The rotator has been configured
with the same defaults that btcd previously used in the seelog config
(10MB file limits with maximum of 3 rolls) but now compresses newly
created roll files. Due to the high compressibility of log text, the
compressed files typically reduce to around 15-30% of the original
10MB file.
This commit fixes a bit of a wart in the configuration file handling
wherein if the config file isn’t found, an error was printed to stderr.
At times, this would cause the testing framework to erroneously mark as
test as failed. Instead, we now keep a particular config file error,
and check that, printing to a warning log level.
This commit fixes a bug introduced by the new multi-chain features of
and which disallowed multiple nodes from beings started locally.
Previously if two local nodes were set to, the _same_ chain, then
they’d both share the same chain data directory which would prevent one
of the nodes from being able to start up properly.
This commit modifies the existing configuration to create instances
that are capable of housing configuration options for a particular
chain such as the rpcuser or rpcpass to distinct structures within
greater configuration. With this new change, it will now be possible
for lnd to be resident on either the litecoin testnets, with simple a
toggle in the main configuration.
The new configuration file will look like the following:
[Bitcoin]
bitcoin.active
bitcoin.testnet=1
bitcoin.rpcuser=kek
bitcoin.rpcuass=kek
Similarly, one would mirror a similar set up in order to be active on
the latest litecoin testnet.
Error `connection refused` was thrown when user tries to get "Alice" to
connect to "Bob" node due to port mismatch introduced in this change [1]
here.
This commit updates the port value to reflect the new change introduced in
[1].

* Update references to old port value
* Omit specifying port during lncli connect
* Fix typo
A common pitfall with new users setting up lnd on test net has been
observed to be the initial RPC credential set up between btcd and lnd.
As of a recent version of btcd now performs automatic RPC credential
set up by generating a random rpcuser and rpcpass on start up.
We now take advantage of this by reading the RPC credentials (if
possible and running in simmer mode). As a result, it is now possible
to simply run: `lnd—testnet` assuming a fresh installation of bcd (with
a set btcd.conf).
Fixes#68.
