While its generally harmless to do so (the messages will simply be
dropped in `PeerManager`) there is a potential race condition where
the FundingLocked message enters the outbound message queue, then
the peer reconnects, and then the FundingLocked message is
delivered prior to the normal ChannelReestablish flow.
We also take this opportunity to rewrite
`test_funding_peer_disconnect` to be explicit instead of using
`reconnect_peers`. This allows it to check each message being sent
carefully, whereas `reconnect_peers` is rather lazy and accepts
that sometimes signatures will be exchanged, and sometimes not.
Quite some time ago, `UnknownRequiredFeature` was only used when a
gossip message has a missing required feature. These days, its also
used for any required TLV which we do not understand in any
message. However, the handling of it was never updated in
`PeerManager`, leaving it printing a warning about gossip and
ignoring the message entirely.
Instead, we send a warning message and disconnect.
Closes#1236, as caught by @jkczyz.
This is harmless outside of debug builds - the feerate will
overflow causing it to either spuriously fail the first check, or
correctly pass it and fail the second check. In debug builds,
however, it panics due to integer overflow.
Found by the `full_stack_target` fuzz test in the
Chaincode-provided continuous fuzzing. Thanks Chaincode!
This removes one more place where we directly access the node_id
secret key in `ChannelManager`, slowly marching towards allowing
the node_id secret key to be offline in the signer.
More importantly, it allows more ChannelAnnouncement logic to move
into the `Channel` without having to pass the node secret key
around, avoiding the announcement logic being split across two
files.
Scorers may have different performance characteristics after seeing
failed and successful paths. Seed the scorer with some random data
before executing the benchmark in order to exercise such behavior.
Passing first_hops to get_route increases the coverage of the benchmark
test. For scorers needing the sending node, it allows for using a single
scorer in the benchmark rather than re-initializing on each iteration.
As a consequence, the scorer can be seeded with success and failure
data.
Refactor generate_routes and generate_mpp_routes into a single utility
for benchmarking. The utility is parameterized with features in order to
test both single path and multi-path routing. Additionally, it is
parameterized with a Score to be used with other scorers.

This resolves a lockorder inversion in
`ChannelManager::finalize_claims` where `pending_outbound_payments`
is locked after `pending_events`, opposite of, for example, the
lockorder in `ChannelManager::fail_htlc_backwards_internal` where
`pending_outbound_payments` is locked at the top of the
`HTLCSource::OutboundRoute` handling and then `pending_events` is
locked at the end.
In https://github.com/lightning/bolts/pull/950, the (somewhat
strange) requirement that error messages be handled even if the
length field is set larger than the size of the package was
removed. Here we change the code to drop the special handling for
this, opting to just fail to read the message if the length is
incorrect.
As required by the warning messages PR, we should simply warn our
counterparty in this case and let them try again, continuing to try
to use the channel until they tell us otherwise.
