Additional changes:
* Update fuzz crate to match ChannelManager's new API
* Update lightning-net-tokio library to match ChannelManager's new ChannelMonitor Deref API
* Update tests to match ChannelManager's new ChannelMonitor Deref API
This exposes the latest Init-context features in the ChannelDetails
passed to the Router during route calculation, which combines those
with the Node-context features tracked from node_announcements to
provide the latest Node-context features in RouteHop structs.
Fields are also added for Channel-context features, though those are
only partially used since no such features are defined today anyway.
These will be useful when determining whether to use new
TLV-formatted onion hop datas when generating onions for peers.
full_stack_target found a crash where we may overflow ruring fee
calculation if a transaction appears on-chain with massive value
available for us to claim. Since these transactions are clearly
bogus, we shouldn't allow full_stack_target to connect them, but
we also improve the error generated by explicitly panicing on them.
Previously, in each of our fuzz tests we had a dummy test which
had a hard-coded hex string which it passed into the fuzz target
so that when a failing test case was found, its hex could be
copied into the test and you could run cargo test to analyze the
failure. However, this was somewhat unwieldy as converting large
tests back and forth between hex and raw files is quite annoying.
Instead, we replace each of those tests with a test in each target
that looks for files in fuzz/test_cases and runs each file it finds.
Since we're editing every bin target anyway, we also automate adding
no_main to libfuzzer builds with #![cfg_attr].
The Features::new() method is nonsense and doesn't describe what
features were being set - we introduce an empty() and supported()
constructors instead.
This merges local and global features into one struct, which is
parameterized by where it appers. The parameterization restricts
which queries can be made and which features can be set, in line
with the latest BOLT 9.
Closes#427.
Simplify interfaces between ChannelMessageHandler and PeerManager,
by switching all ChannelMessageHandler errors to HandleError sent
internally instead of being return. With further refactors in Router
and PeerChannelEncryptor, errors management on the PeerManager-side
won't be splitted between try_potential_handleerror and HandleError
processing.
Inside ChannelManager, we now log MsgHandleErrInternal and send
ErrorAction to PeerManager.
On a high-level, it should allow client using API to be more flexible
by polling events instead of waiting function call returns.
We also update handle_error macro to take channel_state_lock from
caller which should avoid some deadlock potential for some edges
cases.
Filter out IgnoreError in handle_error macro, update test in
consequence.
Instead of having in-memory access to the list of private keys
associated with a channel, we should have a generic API which
allows us to request signing, allowing the user to store private
keys any way they like.
The first step is the (rather mechanical) process of templating
the entire tree of ChannelManager -> Channel impls by the
key-providing type. In a later commit we should expose only public
keys where possible.
This resolves a regression introduced in "Implement bumping engine in
ChannelMonitor::block_connected" in which not all inputs are checked.
Several opportunities to clarify and clean up comments are also taken.
Fix test_bump_penalty_txn_on_revoked_htlcs as now remote claim txn
build the same way than us are going to be register as cleaning
pending_claim_request after ANTI_REORG_DELAY. It means during this
delay we are going to generate invalid bumped claiming txn on
already claimed outpoints. Previously these txn weren't issued
because all their outpoints would have been removed.
Fix full_stack_target by adding more input for FuzzEstimator
A pending claim request may contain a set of multiple outpoints.
If one or multiple of them get claimed by remote party, our in-flight
claiming transactions aren't valid anymore so we need to react
quickly and regenerate claiming transaction with accurate set.
However, a claimed outpoint may be disconnected and we need to resurrect
back outpoint among set of orignal pending claim request.
To guarantee consistency of contentious claimed outpoint we cache it
as OnchainEvent::ContentionsOutpoint and only delete it after
ANTI_REORG_DELAY.
Fix test broken by change, partial claiming on revoked txn
force us to regenerate txn
Given they are only signed by us we can RBF at wish
Fix tests broken by introduction of more txn broadcast
(channel_monitor_network_test)
Add locktime in RemoteHTLC as it's needed to generate
timeout txn.
Add RBF-bumping of justice txn, given they are only signed by us we
can RBF at wish.
Aggregation of bump-candidates and more aggresive bumping heuristics
are left open
Fix tests broken by introduction of more txn broadcast.
Some tests may have a relaxed check (claim_htlc_ouputs_single_tx)
as broadcast bumped txn are now interwining in previous broadcast ones
and breaking simple expectations
Use bumping engine to rebuild claiming transaction in case of partial-
claim of its outpoints set.
This avoids a crash where a channel with a duplicate id is created
immediately after another is closed, where the other still has a
pending funding generation event. Resulting in funding generation
being passed to the wrong channel (which isn't in an appropriate
state).
This simplifies chanmon_fail_consistency greatly and makes it a
tiny bit more realistic. It also sets us up for more
disconnect-relatex events without the complexity blowing up.
This removes the bulk of our reliance on the rand crate in non-test
envs, paving a way towards a syscall-less rust-lightning and WASM.
Since this is a breaking change for full_stack_target (and several
fuzz targets), go ahead and make other changes to make things more
distinct.
Peer may send us a shutdown_scriptpubkey in open_channel or
accept_channel messages. Before to enforce this policy on channel
closing, we want to be sure that our peer has opt-in to it.
