This commit fixes a class of bug that can arise in the channel state machine when a very high throughput workflow is attempted. Since the PaymentDescriptor’s within a commitment pointed directly into the log, any changes to a payment descriptor would also be reflected in all other ones. Due to this mutation possibility, at times, the locateOutputIndex method would fail since the HTLC’s pkScript was modified, causing the channel to fail. We fix this class of bug by simply ensure that once an HTLC has been associated with a particular commitment, then it becomes immutable. |

lnwallet
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.
