Don't interpret decayed data as we've failed to send tiny values

When we're calculating the success probability for min-/max-bucket
pairs and are looking at the 0th' min-bucket, we only look at the
highest max-bucket to decide the success probability. We ignore
max-buckets which have a value below `BUCKET_FIXED_POINT_ONE` to
only consider values which aren't substantially decayed.

However, if all of our data is substantially decayed, this filter
causes us to conclude that the highest max-bucket is bucket zero
even though we really should then be looking at any bucket.

We make this change here, looking at the highest non-zero
max-bucket if no max-buckets have a value above
`BUCKET_FIXED_POINT_ONE`.

Parameterize ChannelManager with MessageRouter

ChannelManager is parameterized by a Router, which must also implement
MessageRouter. Instead, add a MessageRouter parameter such that the
Router and MessageRouter traits can be de-coupled. This simplifies using
something other than DefaultMessageRouter, which DefaultRouter currently
delegates to.

3 weeks agoAdd a `PaymentId` for inbound payments 2024-09-inbound-payment-id
Matt Corallo [Thu, 12 Sep 2024 18:36:58 +0000 (18:36 +0000)]
Add a `PaymentId` for inbound payments

We expect our users to have fully idempotent `Event` handling as we
may replay events on restart for one of a number of reasons. This
isn't a big deal as long as all our events have some kind of
identifier users can use to check if the `Event` has already been
handled.

For outbound payments, this is the `PaymentId` they provide in the
send methods, however for inbound payments we don't have a great
option.

`PaymentHash` largely suffices - users can simply always claim in
response to a `PaymentClaimable` of sufficient value and treat a
`PaymentClaimed` event as duplicate any time they see a second one
for the same `PaymentHash`. This mostly works, but may result in
accepting duplicative payments if someone (incorrectly) pays twice
for the same `PaymentHash`.

Users could also fail for duplicative `PaymentClaimable` events of
the same `PaymentHash`, but doing so may result in spuriously
failing a payment if the `PaymentClaimable` event is a replay and
they never saw a corresponding `PaymentClaimed` event.

While none of this will result in spuriously thinking they've been
paid when they have not, it does result in some pretty awkward
semantics which we'd rather avoid our users having to deal with.

Instead, here, we add a new `PaymentId` which is simply an HMAC of
the HTLCs (as Channel ID, HTLC ID pairs) which were included in the
payment.

Add an `inbound_payment_id_secret` to `ChannelManager`

In the next commit we'll start generating `PaymentId`s for inbound
payments randomly by HMAC'ing the HTLC set of the payment. Here we
start by defining the HMAC secret for these HMACs.

This requires one small test adaptation and a full_stack_target
fuzz change because it changes the RNG consumption.

In the next commit we'll change the order of HTLCs in

our current functional tests check that the HTLCs are provided in
the order they expect (the order they were received). Instead, here
we only validate that each claimed HTLC matches one expected path.

Fix bug where we double-pay an offer due to stale manager

- An outbound payment is AwaitingInvoice
- We receive an invoice and lock the HTLCs into the relevant ChannelMonitors
- The monitors are successfully persisted, but the ChannelManager fails to

the monitor on startup and transition the incorrectly-AwaitingInvoice payment
