This commit adds a check that will make LightningChannel reject a
received commitment if it is accompanied with too many HTLC signatures.
This enforces the requirement in BOLT-2, saying:
if num_htlcs is not equal to the number of HTLC outputs in the local commitment transaction:
* MUST fail the channel.
A test exercising the behaviour is added.
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.
