lnwire: detect invalid timestamp field #9084
Conversation
Currently if an incorrect number of timestamps is given, we fail later on in the GossipSyncer. It makes more sense to fail right away, since we already do that for incorrect SCID formats (e.g., unsorted or duplicate SCIDs). There is already a matching check in Encode for incorrect number of timestamps, so adding this check to Decode makes things symmetric.
The check is no longer required, as it is now done during decoding.

Yes this change makes sense, aren't the fuzz tests run somewhere in some kind CI or was this a new input to the fuzzer by Goegge ?
Missing Release-Notes
The existing fuzz corpus is run during CI to test for regressions, but no new fuzzing is done. What happened is that @ellemouton added the new timestamp field, and we never reran the fuzz tests to exercise the new code. This is more motivation to set up continuous fuzzing (either #5965 or something custom). |
