ChanUpdate timestamps are now restircted so that they cannot be
more than two weeks into the future. Moreover channels with both
timestamps in the ReplyChannelRange msg either too far in the past
or too far in the future are not queried.
Moreover fix unitests.
In this commit, we fix a bug that would cause a global message router to
be stopped anytime a peer disconnected. The global msg router only
allows `Start` to be called once, so afterwards, no messages would
properly be routed.
With this commit, we allow the `MsgRouter` to be available in the
`ImplementationCfg`. With this, programs outside of lnd itself are able
to now hook into the message processing flow to direct handle custom
messages, and even normal wire messages.
Over time with this, we should be able to significantly reduce the size
of the peer.Brontide struct as we only need all those deps as the peer
needs to recognize and handle each incoming wire message itself.
In this commit, we add a new abstract message router. Over time, the
goal is that this message router replaces the logic we currently have in
the readHandler (the giant switch for each message).
With this new abstraction, can reduce the responsibilities of the
readHandler to *just* reading messages off the wire and handing them off
to the msg router. The readHandler no longer needs to know *where* the
messages should go, or how they should be dispatched.
This will be used in tandem with the new `protofsm` module in an
upcoming PR implementing the new rbf-coop close.
Initially in lnd, we didn't store the extra TLV data that could be
dangling off of gossip messages. This was fixed initially in lnd v0.5
with this PR: https://github.com/lightningnetwork/lnd/pull/1825.
Within the PR, we incorrect set the `ExtraOpaqueData` (extra TLV blob)
of the `ChannelAnnouncement` to the value stored in `edge`, which is
actually our channel update. As 6-ish years ago we didn't yet have
anything that used the TLV gossip fields, this went unnoticed.
Fast forward to 2024, we shipped an experimental version of inbounbd
fees. This starts to store additional data in the `ExtraOpaqueData`
field, the TLV for the inbound fee. Initially, everything is valid when
the first `ChannelAnnouncement` is sent, but as soon as a user attempts
to set an inbound fee policy, we'd incorrectly swap in that new
serialized TLV for the _channel announcement_:
841e24399c (diff-1eda595bbebe495bd74a6a0431c46b66cb4e8b53beb311067c010feac2665dcbR2560).
Since we're just trying to generate a new `channel_update`, we don't
also regenerate the signature for the `channel_announcement` message. As
a result, we end up storing a `channel_announcement` with an invalid sig
on disk, continuing to broadcast that to peers.
Add a new bumpforceclosefee rpc endpoint to the wallet server.
Move the logic from the lncli level to the wallet server rpc level.
This is more in line with a proper client-server design.
wallet lncli: use new bumpforceclosefee endpoint.
Besides using the new bumpforceclosefee rpc endpoint we also enable the
bumping of taproot anchor channels.
The BlindedPathConfig struct is nice for invoice creation but when we
use the Invoice message for viewing an invoice, it would be nicer to see
an "is_blinded" field.
We have existing logic to attempt to reliably send a channel update to
the remote peer. In the wild, we've seen this fail, as it's possible
right when we send the update the peer disconnects.
In this commit, we implement a simple fix which is just to send the chan
update each time we connect to the remote party.
Fixes https://github.com/lightningnetwork/lnd/issues/6870.
This commit adds two functional options to the zpay32.Decode function.
`WithKnownFeatureBits` allows the caller to overwrite the default set of
known feature bits used by the function.
`WithErrorOnUnknownFeatureBit` allows the caller to instruct the
function to error out if the invoice that is decoded contaijns unknown
feature bits. We then use this new error-out option from the
`rpcServer`'s `extractPaymentIntent` method.
In this commit, we adjust BuildBlindedPaymentPaths to only error out
completely if none of the paths it received from FindRoutes resulted in
a usable blinded path.
since `AddInvoiceData` is config _per invoice_ where as `AddInvoiceConfig`
is config for the invoice server itself and so pretty much should stay
the same for the lifetime of LND. This change sets us up for moving some
of the blinded path config options to be changeable per AddInvoice call
rather that having fixed config values in the config file.
