We only want to register the bbolt DB backend ("bdb") when we're not
compiling for a JS/WASM build targets. That's why we want to have that
import in only one file that we can add a build tag to. We remove it in
two other places since only one import is enough anyway.
In this commit, in order to allow the test added in the prior commit to
pass, we'll increment the mockHTLCAmt value by 1 to ensure we never
attempt to add a zero value HTLC.
Fixes#5468
As is, if the remote party proposes a min HTLC of 0 `mSat` to us, then
we won't ever be able to _send outgoing_ in the channel as the
`MayAddOutgoingHtlc` will attempt to add a zero-value HTLC, which isn't
allowed within the protocol.
The default channels created actually already use a min HTLC value of
zero within the tests, so this test case fails as is.
This commit adds a new struct AnchorResolutions which wraps the anchor
resolutions for local/remote/pending remote commitment transactions. It
is then returned from NewAnchorResolutions. Thus the caller knows how to
retrieve a certain anchor resolution.
In this commit, we add a check inside EstimateFeePerKW for bitcoind so
that when the conf target exceeds the maxBlockTarget, we will use
maxBlockTarget instead.
This commit aims to address a flaw in our anchor reserve enforcement
logic in which an inbound "legacy" channel (i.e. a channel with a
commitment type that precedes anchors) would be rejected by the
recipient if they have at least one opened channel using the anchors
commitment type and do not have enough on-chain funds to meet the
anchors reserve.
Otherwise, we would get non-standard txn's and fail to broadcast
them when cooperatively closing a channel. This wouldn't affect
funds security as no HTLCs would be active to steal. This is just
a safety measure as we should only generate standard txn's.
Fixes#5287.
The PSBT spec is a bit vague when it comes to the WitnessUtxo field of
an input as it's not strictly required for witness inputs. Therefore
Electrum for example does not include the field.
We need to make the SegWit input check a bit more elaborate by looking
at the output script of the UTXO and also the redeem script in case it's
a nested SegWit spend.
Since private channels (most likely) won't be used for routing other
than as last hop, they bear a smaller risk that we must quickly force
close them in order to resolve a HTLC up/downstream.
In the case where it actually has to be force to resolve a payment (if
it is the first/last hop on a routed payment), we can assume that the
router will have UTXOs available from the reserved value from the
incoming public channel.
We cap the maximum value we'll reserve for anchor channel fee bumping at
10 times the per-channel amount such that nodes with a high number of
channels don't have to keep around a very large amount for the unlikely
scanario that they all close at the same time.
This commit ensures that for the neutrino implementation of
lnwallet.BlockChainIO, the neutrino GetBlock method is called directly
(since it already uses the blockcache). It also ensures that the block
cache mutex for the given hash is locked before the call to GetBlock.
The previous behavior would allow updates to be overwritten in some
scenarios. Upon restart, this would lead to a missing settle/fail in
the update logs.
Add a dust-limit to `CoinSelect` and let the fee estimation consider if a change output is needed or not, assuring that if the change is below the dust-limit it will go towards the fee instead.
This commit adds a RevocationKeyLocator field to the OpenChannel
struct so that the SCB derivation doesn't have to brute-force the
sha chain root key and match the public key. ECDH derivation is now
used to derive the key instead of regular private key derivation a
la DerivePrivKey. The legacy can still be used to recover old
channels.

lnwire: update quickcheck tests, use constant for Error
multi: update unit tests to pass deep equal assertions with messages
In this commit, we update a series of unit tests in the code base to now
pass due to the new wire message encode/decode logic. In many instances,
we'll now manually set the extra bytes to an empty byte slice to avoid
comparisons that fail due to one message having an empty byte slice and
the other having a nil pointer.
