The upcoming ChannelManager::create_bolt11_invoice will not support
setting a specific creation time, so remove that functionality from the
invoice_utils functions. This will avoid duplicate code when
deprecating.
`indexmap` 2.6.0 upgraded to `hashbrown` 0.15, which unfortunately
bumped their MSRV to rustc 1.65 with the 0.15.1 release. So we pin
`indexmap` to 2.5.0 to fix our MSRV CI.
Try to make it a bit more clear that there are downsides to solely
relying on `lightning-net-tokio`, and it's still recommended to
occasionally call this function in a separate loop.
Instead of first building a map from peers to a list of channels
then pulling out of that to build the `per_peer_state`, we build
`per_peer_state` immediately and store channels in it immediately.
This avoids an unnecessary map indirection but also gives us
access to the new fields in `per_peer_state` when reading
`Channel`s which we'll need in a coming commit.
In 453ed11f80 we started tracking the
counterparty's `node_id` in `HTLCPreviousHopData`, however we were
still trying to look it up using `prev_short_channel_id` in
`claim_funds_from_hop`.
Because we now usually have the counterparty's `node_id` directly
accessible, we should skip the `prev_short_channel_id` lookup.
This will also be more important in the next commit where we need
to look up state for our counterparty to generate
`ChannelMonitorUpdate`s whether we have a live channel or not.
When a channel is closed, we have to call
`update_maps_on_chan_removal` in the same per-peer-state lock as
the removal of the `ChannelPhase` object. We forgot to do so in
`ChannelManager::signer_unblocked` leaving dangling references to
the channel.
We also take this opportunity to include more context in the
channel-closure log in `ChannelManager::signer_unblocked` and add
documentation to `update_maps_on_chan_removal` and
`finish_close_channel` to hopefully avoid this issue in the future.
`update_maps_on_chan_removal` is used to perform `ChannelManager`
state updates when a channel is being removed, prior to dropping
the `peer_state` lock. In a future commit we'll use it to update
fields in the `per_peer_state`, but in order to do so we'll need to
have access to that state in the macro.
Here we get set up for this by passing the per-peer state to
`update_maps_on_chan_removal`, which is sadly a fairly large patch.
1b711ed15f changed it so that we can
enqueue broadcast gossip messages to peers even though their buffer
is full as long as its our `ChannelMessageHandler` doing it. This
broke a debug assertion that the buffer isn't too large when
appending the broadcast message which is simply dropped here.

The BOLT12 spec defines an experimental TLV range that is allowed in
offer and invoice_request messages. The remaining TLV-space is for
experimental use in invoice messages. Allow this range when parsing an
invoice and include it when signing one.
Payer metadata is generated from the invreq TLVs and should included
those in the experimental range. When verifying invoice messages, these
TLVs must be included. Modify the BOLT12 verification tests to cover
them.
The BOLT12 spec defines an experimental TLV range that are allowed in
invoice_request messages. Allow this range when parsing an invoice
request and include those bytes in any invoice. Also include those bytes
when verifying that a Bolt12Invoice is for a valid InvoiceRequest.
Offer metadata is generated from the offer TLVs and should included
those in the experimental range. When verifying invoice request and
invoice messages, these TLVs must be included. Similarly, OfferId
construction should included these TLVs as well. Modify the BOLT12
verification tests to cover these TLVs.
The BOLT12 spec defines an experimental TLV range that are allowed in
offer messages. Allow this range when parsing an offer and include those
bytes in any invoice requests. Also include those bytes when computing
an OfferId and verifying that an InvoiceRequest is for a valid Offer.
Upcoming commits will allow parsing BOLT12 messages that include TLV
records in the experimental range. Include these ranges when verifying
messages since they will be included in the message bytes.
Passing bytes directly to InvoiceContents::verify improves readability
as then a TlvStream for each TLV record range can be created from the
bytes instead of needing to clone the TlvStream upfront. In an upcoming
commit, the experimental TLV record range will utilize this.
Add a utility function for iterating over Offer TLV records contained in
any valid TLV stream bytes. Using a common function ensures that
experimental TLV records are included once they are supported.
When constructing UnsignedInvoiceRequest or UnsignedBolt12Invoice, use a
separate field for experimental TLV bytes. This allows for properly
inserting the signature TLVs before the experimental TLVs when signing.
Async payments include the original invoice request in the payment onion.
Since invreqs may include blinded paths, it's important to factor them into our
max path length calculations since they may take up a significant portion of
the 1300-byte onion.
While in the last commit we began including invoice requests in async payment
onions on initial send, further work is needed to include them on retry. Here
we begin storing invreqs in our retry data, and pass them along for inclusion
in the onion on payment retry.
Per BOLTs PR 1149, when paying a static invoice we need to include our original
invoice request in the HTLC onion since the recipient wouldn't have received it
previously.
Past commits have set us up to include invoice requests in outbound async
payment onions. Here we actually pull the invoice request from where it's
stored in outbound_payments and pass it into the correct utility for inclusion
in the onion on initial send.
Per BOLTs PR 1149, when paying a static invoice we need to include our original
invoice request in the HTLC onion since the recipient wouldn't have received it
previously.
When transitioning outbound payments from AwaitingInvoice to
StaticInvoiceReceived, include the invreq in the new state's outbound payment
storage for future inclusion in an async payment onion.
Per BOLTs PR 1149, when paying a static invoice we need to include our original
invoice request in the HTLC onion since the recipient wouldn't have received it
previously.
Add a new invoice request parameter to outbound_payments and channelmanager
send-to-route internal utils. As of this commit the invreq will always be
passed in as None, to be updated in future commits.
Per BOLTs PR 1149, when paying a static invoice we need to include our original
invoice request in the HTLC onion since the recipient wouldn't have received it
previously.
