To support route blinding, we want to split OnionHopData into two separate
structs, one for inbound onions and one for outbound onions. This is because
blinded payloads change the fields present in the onion hop data struct based
on whether we're sending vs receiving (outbound onions include encrypted blobs,
inbound onions can decrypt those blobs and contain the decrypted fields
themselves).
In upcoming commits, we'll add variants for blinded payloads to the new
InboundPayload enum.
Fuzz testing bech32 decoding along with deserializing the underlying
message can result in overly exhaustive searches. Instead, the message
deserializations are now fuzzed separately. Add fuzzing for bech32
decoding.
An invoice is serialized as a TLV stream and encoded as bytes. Add a
fuzz test that parses the TLV stream and deserializes the underlying
Invoice. Then compare the original bytes with those obtained by
re-serializing the Invoice.
An invoice request is serialized as a TLV stream and encoded as bytes.
Add a fuzz test that parses the TLV stream and deserializes the
underlying InvoiceRequest. Then compare the original bytes with those
obtained by re-serializing the InvoiceRequest.
A refund is serialized as a TLV stream and encoded in bech32 without a
checksum. Add a fuzz test that parses the unencoded TLV stream and
deserializes the underlying Refund. Then compare the original bytes with
those obtained by re-serializing the Refund.
An offer is serialized as a TLV stream and encoded in bech32 without a
checksum. Add a fuzz test that parses the unencoded TLV stream and
deserializes the underlying Offer. Then compare the original bytes with
those obtained by re-serializing the Offer.
Also update the fuzz ChaCha20Poly1305 to not mark as finished after a single
encrypt_in_place. This is because more bytes may still need to be encrypted,
causing us to panic at the assertion that finished == false when we go to
encrypt more.
Also fix unused_mut warning in messenger + add log on OM forward for testing
Our fuzz tests previously only printed the log output of the first
fuzz test case to fail. This commit changes that (with lots of
auto-generated updates) to ensure we print all log outputs.
This changes the LICENSE file and adds license headers to most files
to relicense under dual Apache-2.0 and MIT. This is helpful in that
we retain the patent grant issued under Apache-2.0-licensed work,
avoiding some sticky patent issues, while still allowing users who
are more comfortable with the simpler MIT license to use that.
See https://github.com/rust-bitcoin/rust-lightning/issues/659 for
relicensing statements from code authors.
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].
