funding: query fee estimator and scale to fee-per-kw when making chan
This commit modifies the funding workflow slightly to move the querying
to the fee estimator (for the new channel) into the fundingManager
rather than within the LightningWallet layer. When querying to
FeePerWeight, we now multiply by 1000 to arrive at fee-per-kw.

Additionally, we now also properly thread through the fee-per-kw
offered by the initiator the to the responder of the channel workflow.

funding: fix bug that double counts "pending channels" in GetInfo
This commit fixes a bug that double counts the number of pending
channels in GetInfo. Previously we weren’t yet storing the pending
channels on disk, we are now but comparing both the disk channel and
the channels within memory leads us to double count channels. To fix
this, we now only count the database channels.

Note that this NumPendingChannels method can now be removed as it’s no
longer needed.

funding: announce channel after confirmation, activate channel after FundingLocked
This commit modifies the order of operations after a channel has been
detected as fully opened. Rather than waiting until we receive the
FundingLocked message to announce the channel, we now do so immediately
after we detect the channel has been opened.

Additionally, we also patch a possible dead-lock bug by ensuring that
the RevokeAndAck message is always sent _after_ the FundingLocked
message. We do this by only passing the newly created channel too the
relevant sub-systems _after_ we receive the FundingLocked message. This
movement also serves to pave the way for our switch to the spec’s
funding workflow, as once we remove the initial revocation window,
there’ll be no way for us to initiate a state transition until we
receive the FundingLocked message from the remote party.

funding+peer: switch to using new channel ID's
This commit modifies the way the fundingManager tracks pending funding
workflows internally. Rather than using the old auto-incrementing
64-bit pending channel ID’s, we now use a 32-byte pending channel ID
which is generated using a CSPRG. Additionally, once the final funding
message has been sent, we now de-multiplex the FundingLocked message
according to the new Channel ID’s which replace the old ChannelPoint’s
and are exactly 32-bytes long.

funding: fix bug that marks channel as open when ChainNotifier exist early
This commit fixes a bug that resulted from properly failing to do a
2-value read from the confirmation notification channel. If the
ChainNotifier was shutting down, then a nil read could be generated
which may prematurely mark the channel as open, and also trigger a nil
pointer panic exception below when the confDetails are accessed.

We fix this issue, by ensuring that we check the second value to see if
the channel has been closed or not.

e549a3f0ed fundingmanager: move final funding steps from wallet to funding manager.
Once a channel funding process has advanced to the point of broadcasting
the funding transaction, the state of the channel should be persisted
so that the nodes can disconnect or go down without having to wait for the
funding transaction to be confirmed on the blockchain.

Previously, the finalization of the funding process was handled by a
combination of the funding manager, the peer and the wallet, but if
the remote peer is no longer online or no longer connected, this flow
will no longer work. This commit moves all funding steps following
the transaction broadcast into the funding manager, which is available
as long as the daemon is running.

b21bd351e8 fundingmanager: change funding messages to use server.sendToPeer
Previously, during the channel funding process, peers sent wire
messages using peer.queueMsg. By switching to server.sendToPeer, the
fundingManager is more resilient to network connection issues or system
restarts during the funding process. With server.sendToPeer, if a peer
gets disconnected, the daemon can attempt to reconnect and continue the
process using the peer’s public key ID.

funding: disallow channel creation before lnd is synced to the chain
This commit adds a new restriction around funding channels at the
daemon level: lnd nodes will not allow either the initiation or the
acceptance of a channel before the node is fully synced to the best
known chain.

This fixes a class of bug that arises when a new node joins the network
and either attempts to open a channel or has a channel extended to them
before the node is fully synced to the network.

lnwire+lnd: Make Logging Messages Great Again
This commit modifies the login of sent/recv’d wire messages in trace
mode in order utilize the more detailed, and automatically generated
logging statements using pure spew.Sdump.

In order to avoid the spammy messages due to spew printing the

introduce a new logging function to unset the curve paramter to it
isn’t printed in its entirety. To insure we don’t run into any panics
as a result of a nil pointer defense, we now copy the public keys
during the funding process so we don’t run into a panic due to
modifying a pointer to the same object.

lnd: fully integrate the ChannelRouter of the new routing package
This commit fully integrates the ChannelRouter of the new routing
package into the main lnd daemon.

A number of changes have been made to properly support the new
authenticated gossiping scheme.

Two new messages have been added to the server which allow outside
services to: send a message to all peers possible excluding one, and
send a series of messages to a single peer. These two new capabilities
are used by the ChannelRouter to gossip new accepted announcements and
also to synchronize graph state with a new peer on initial connect.

The switch no longer needs a pointer to the routing state machine as it
no longer needs to report when channels closed since the channel
closures will be detected by the ChannelRouter during graph pruning
when a new block comes in.

Finally, the funding manager now crafts the proper authenticated
announcement to send to the ChannelRouter once a new channel has bene
fully confirmed. As a place holder we have fake signatures everywhere
since we don’t properly store the funding keys and haven’t yet adapted
the Signer interface (or create a new one) that abstracts out the
process of signing a generic interface.

lnd: switch to using the connmgr for listening and persistent conns
This commit revamps the way in bound and outbound connections are
handled within lnd. Instead of manually managing listening goroutines
and also outbound connections, all the duty is now assigned to the
connmgr, a new btcsuite package.

The connmgr now handles accepting inbound (brontide) connections and
communicates with the server to hand off new connections via a
callback. Additionally, any outbound connection attempt is now made
persistent by default, with the assumption that (for right now),
connections are only to be made to peers we wish to make connections
to. Finally, on start-up we now attempt to connection to all/any of our
direct channel counter parties in order to promote the availability of
our channels to the daemon itself and any RPC users.

This commit introduces a new sub-system into the daemon whose job it is

Upon start-up the breachArbiter will query the database for all active
channels, launching a goroutine for each channel in order to be able to
take action if a channel breach is detected. The breachArbiter is also
responsible for notifying the htlcSwitch about channel breaches in
order to black-list the breached linked during any multi-hop forwarding
decisions.

With this change clients can now receive updates that the request is
pending (final message has been sent to the target client), or that the

simnet, etc) has been finalized. Previously a command line option was
present to swap networks, but the RPC port wouldn’t automatically be
updated to reflect the network.

lnd: implement pendingchannels RPC
This commit implements the “pendingchannels” RPC within the rpcserver.
This RPC allows callers to receive details concerning the current
pending channels associated with the daemon. Pending channels are those
waiting for additional confirmations before they can be considered
opened/closed.

At the time of this commit, only open channels are shown. A future
commit will also add the confirmation updates, along with information
for close channels.

lnd: implement open+close channel workflow in daemon
This commit adds the necessary plumbing within the server, peer, and
rpcServer to handle opening and cooperatively closing a channel with a
remote peer.

Many new data structures have been added to the peer in order to allow
it to efficiently manage opening+.losing new/existing lightning
channels. Additional documentation has been added to several methods
within the peer struct, with some minor renaming along with way. The
peer has also gained a dedicated goroutine whose job it is to manage
any requests pertaining to opening, or closing any channels with the
remote peer.

The messages have been added to lnrpc define the requests and responses
to channel open+close messages. Additional channel logic has been added
between the rpcServer, peer, and server in order to properly manage the
necessary synchronization.

lnd: introduce the fundingManager
This commit introduces the fundingManger which is used as a bridge
between the wallet’s internal ‘ChannelReservation’ workflow, and the
wire protocol’s funding messages.

 The funding manger is responsible for progressing the workflow, and
communicating any errors generated during the workflow back to the
source peer.
