In this commit, we ensure that the packet queue will always exit, by
continually signalling the main goroutine until it atomically sets a
bool that indicates its has been fully shutdown. It has been observed
that at times the main goroutine will wake up (due to the signal), but
then bypass the select and actually miss the quit signal, as a result
another signal is required. We'll continue to signals in a lazy loop
until the goroutine has fully exited.
This commit moves the generic interface for
Lightning Network peers so that it can be
imported directly into the switch and gossiper.
Eventually, the majority of the peer logic
would be moved into this package for testing
and modularization.
In this commit we modify the existing sendtoroutes command such that
users can either specify the route over stdin (using the special '-'
flag), via the keyword argument, or via the positional argument.
In this commit, we modify the logic for the two primary payment related
RPCs to reduce duplication, indentation, and consolidate logic. As a
result, we'll now accept rpcPaymentIntents, turn those into regular
paymentIntents (convert from proto) before finally dispatching via
unified function.
In this commit, we modify the recent refactoring of the mission control
sub-system to overload the existing payment session, rather than create
a brand new one. This allows us to re-use more of the existing logic, and
also feedback into mission control the failures incurred by any user
selected routes.
This commit add 3 integration tests for send-to-route RPC call.
One test ensures that single-hop payments are processed. Another test
checks that payments through a multi-hop route are processed. Lastly,
there is a test to check error propagation while sending payments via fake
predefined route.
This commit removes a possible deadlock in the switch,
which can be triggered under certain failure conditions.
Previously, we would acquire the link's read lock for
the duration of HtlcSatisfiesPolicy, though we only
need to use it grab the current policy. The deadlock could
be caused in the cases where we attempt to log the failure,
which access the read-protected ShortChanID method.
In this commit, we address the meaning of the inbound parameter to
peerConnected. An inbound connection is defined as a connection
initiated by the peer, rather than ourselves.
We also update the inbound value for the peerConnected calls within
OutboundPeerConnected and InboundPeerConnected to reflect the definition
above.
We remove the internale broadcastMessage method, and instead handle the
mutex handling within BroadcastMessage. This lets us hold the mutex only
when neccessary.
This commit removes the sendToPeer method from the server, and instead
moves the necessary logic into SendToPeer. This let's us make the mutex
acquisition more fine-grained, only holding it while reading from the
peer map. Earlier it was required to be held during the whole call to
sendToPeer, as the method would access the map internally.
This commit synchronizes the in-memory cache with the
on-disk state to ensure the waiting proof store is
externally consistent. Currently, there are scenarios
where the in-memory state is updated, and not reverted
if the write fails. The general fix is to wait to apply
modifications until the write succeeds, and use a
read/write lock to synchronize access with db operations.
In this commit, we add and enforce a min fee rate for commitment
transactions created, and also any updates we propose to the remote
party. It's important to note that this is only a temporary patch, as
nodes can dynamically raise their min fee rate whenever their mempool is
saturated.
Fixes#1330.
In this commit, we fix an existing bug in the new graph query sync
feature. Before this commit, when a block is pruned, we would never
actually delete the update index entries. This is due to the fact that
we would attempt to delete the entries from the update index _after_ we
had already removed the edges from the update index.
We fix this by simply swapping the order: first we delete from the
update index, then we delete the edges themselves. A test ensuring that
the entires are cleared (which failed before this commit), has been
added.
In this commit, we go through the codebase looking for TCP address
assumptions and modifying them to include the recently introduced onion
addresses. This enables us to fully support onion addresses within the
daemon.
In this commit, we update the way we reestablish inbound connections if
we lose connectivity to a node we have an open channel with. Rather than
fetching the node's advertised port, we'll fetch one of their advertised
addresses instead. This ensure that if the remote node is running behind
a proxy, we do not see the proxy's address.
In this commit, we allow the daemon to use the recently introduced Tor
Controller implementation. This will automatically create a v2 onion
service at startup in order to listen for inbound connections over Tor.

In this commit, we fix a bug where a fallback SRV lookup would leak
information if `lnd` was set to route connections over Tor. We solve
this by using the network-specific functions rather than the standard
ones found in the `net` package.
In this commit, we now allow connections to onion addresses due to
recently adding support to properly parse them.

In this commit, we allow `lnd` to properly parse onion addresses in
order to advertise them to the network when set through the
`--externalip` flag.

In this commit, we update the set of Tor flags to use sane defaults when
not specified. We also include some new flags related to the recent
onion services changes. This allows users to easily get set up on Tor by
only specifying the tor.active flag. If needed, the defaults can still
be overridden.
In this commit, we add our inital implementation of a Tor Controller.
This commit includes the ability for the controller to automatically
signal the Tor daemon to create a v2 onion service. This will be
expanded later on to support creating v3 onion services.
Before allowing the controller to interact with the Tor daemon, the
connection must be authenticated first. This commit includes support for
the SAFECOOKIE authentication method as a sane default.

In this commit, we fix an issue where connections made through Tor's
SOCKS proxy would result in the remote address being the address of the
proxy itself
We fix this by using an internal proxyConn struct that sets the correct
address at the time of the connection.
