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 fix an existing grouting leak within the contract
court package. If a goroutine dies, but it doesn’t actually cancel the
block epoch notification that it requested, then it’s possible to leak
thousands of gorutines. To remedy this situation, we ensure that we’ll
*always* cancel the epoch notification once the goroutine has exited.
In this commit, we fix an existing bug that would result in some
payments getting “stuck”. This would happen if one side restarted
before the channel was fully locked in. In this case, since upon
re-connection, the link will get added to the switch with a *short
channel ID of zero*. If A then tries to make a multi-hop payment
through B, B will fail to forward the payment, as it’ll mistakenly
think that the payment originated from a local-subsystem as the channel
ID is zero. A short channel ID of zero is used to map local payments
back to their caller.
With fix this by allowing the funding manager to dynamically update the
short channel ID of a link after it discovers the short channel ID.
In this commit, we fix a second instance of reported “stuck” payments
by users.
In this commit, we fix an existing bug within the funding manager. A
channel barrier only needs to be create if upon startup the channel is
still pending. Otherwise, we’ll re-create the funding barrier
unnecessarily. This can lead to bugs when initiating payments between a
channels’ lock in and when it’s announced to the together network. If
during this period, a user attempts a payment, then the response won’t
be archived, as the grouting will be blocked waiting on the channel
barrier to close.
To fix this, we only re-create the barrier if the channel hasn’t been
confirmed.
This eliminates one source of reported “stuck payments”.
In this commit, we remove a server shutdown statement that was executed
after we obtained the wallet’s password from the user over RPC. This
was unnecessary as we already close the listener below. Before this
commit, users would see a weird benign error message. With these code
deletion, the message disappears.
This commit updates the tests for checking a links Bandwidth()
calculation, after the change that made us use the remoteACKedIndex
instead of the logIndex when calculating it. The main result of this
change is that we never consider incoming updates before they are
acked, when calculating the bandwidth. This is because this was
inconsistent with the state we actually end up signing later on.
This commit adds a test that trigger a case where the balance
could end up being negative when we used the logIndex when
calculating the channel's available balance. This could
happen when the logs got out of sync, and we would use
the balance from a settled HTLC even though we wouldn't
include it when signing the next state.
This commit introduces a new Ticker interface, that can be used
to control when the batch timer should tick. This is done to be
able to more easily control the ticker during tests. The batch
timer is wrapped in the new BatchTicker struct, and made part
of the config together with BatchSize.
In this commit, we fix an issue that was recently introduced to the way
we handle historical dispatches for the neutrino notifier. In a recent
change, we no return an error if we’re unable to actually find the
transaction that spends an outpoint. If this is the case, then the
outpoint is actually unspent, and we should proceed as normal.
This commit reworks the macaroon authentication framework to use the
v2 macaroon format and bakery API. It also replaces the code in each
RPC method which calls the macaroon verifier with interceptors which
call the macaroon verifier instead. In addition, the operation
permissions are reworked to fit the new format of "allow" commands
(specifically, entity/operation permissions instead of method
permissions).
Appendix C of BOLT 03 contains a series of test vectors asserting that
commitment, HTLC success, and HTLC timeout transactions are created
correctly. Here the test cases are transcribed to Go structs and
verified.
We also break out some logic need to tests that bypass the constructor
and remove some redundant fields.
Before this commit, if the remaining change was small enough, then it
was possible for us to generate a non-std funding transaction. This is
an issue as the txn would fail to propagate, meaning funds could
potentially be stuck in limbo if users didn't manually drop their
transaction history.
To avoid this scenario, we won't create a change output that is dusty.
Instead, we'll add these as miner fees.
Fixes#690.
In this commit, we modify the logic executed when we decide that we
need to fail a funding flow. Before this commit, if the remote party
disconnected while we were attempting to fail the funding flow with an
error. Then we'd never actually cancel the reservation. This meant that
any inputs selected for that transaction would be locked until a
restart.
We fix this issue by always cancelling the reservation first, and
ensuring that failure to cancel the reservation doesn't prevent us from
sending the error.
Partially addresses #710.
It seems that at some point the installation docs of the
https://github.com/lightninglabs/lightning-dev-site/ was identical to
this file (without page navigation + next steps).
Seems that this commit did not get ported to this repo:

In this PR the info for macaroons and noencryptwallet is copied over
from the above mentioned commit.
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.
