This commit fixes a class of bug that currently exists within the cooperative closure methods for the channel state machine. As an example, due to the current hard coded fees, if one of the outputs generated within the generated closure transaction has a negative output, then the initiating node would gladly forward this to the remote node. The remote node would then reject the closure as the transaction is invalid. However, the act of completing the closure would cause the remote node’s state machine to shift into a “closed” state. As a result, any further closure attempts by the first node (force or regular) would go unnoticed by the remote node. We fix this issue by ensuring the transaction is “sane” before initiating of completing a cooperative channel closure. At test case has been added exercising the particular erroneous case reported by “moli” on IRC. |

The lnwallet package implements an abstracted wallet controller that is able to drive channel funding workflows, a number of script utilities, witness generation functions for the various Lightning scripts, revocation key derivation, and the commitment update state machine.
The package is used within lnd as the core wallet of the daemon. The wallet
itself is composed of several distinct interfaces that decouple the
implementation of things like signing and blockchain access. This separation
allows new WalletController implementations to be be easily dropped into
lnd without disrupting the code base. A series of integration tests at the
interface level are also in place to ensure conformance of the implementation
with the interface.
