This commit fixes #4118 by properly sorting the HTLC signatures sent over the wire to match the BOLT3 BIP69+CLTV sorting of the commitment outputs. To do so, we expose the slice of cltv deltas for HTLCs on the unsigned commitment after applying the commitment sorting. This will be used to locate the proper output index, as the CLTV serves as a tie breaker between HTLCs that otherwise have the same payment hash and amount. Note that #3412 fixed the issue partially by ensuring the commitment was constructed properly (and the second-level prev outpoint's txid was correct), but failed to address that the HTLC signatures were still sent out in the incorrect order. With this, we pass the test case introduce in the next commit. |

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 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.
