From f62a96ea93e241ad00859e508df988f5b5ab6f92 Mon Sep 17 00:00:00 2001 From: Matt Corallo Date: Sat, 23 Dec 2023 19:13:34 +0000 Subject: [PATCH] Use arbitrary config object in full_stack_target fuzzer As we've added more and more configuration parameters which change our behavior, we're increasingly missing coverage in the general `full_stack_target` fuzzer. Sadly, a reachable `unwrap` slipped in uncaught that should have been stopped by the `full_stack_target`. Here, we update the `full_stack_target` fuzzer to read a full config object to substantially increase coverage. --- fuzz/src/full_stack.rs | 47 ++++++++++---------------- lightning/src/util/config.rs | 64 ++++++++++++++++++++++++++++++++++++ 2 files changed, 81 insertions(+), 30 deletions(-) diff --git a/fuzz/src/full_stack.rs b/fuzz/src/full_stack.rs index 2df63cf54..c7afd69bb 100644 --- a/fuzz/src/full_stack.rs +++ b/fuzz/src/full_stack.rs @@ -48,11 +48,11 @@ use lightning::onion_message::messenger::{Destination, MessageRouter, OnionMessa use lightning::routing::gossip::{P2PGossipSync, NetworkGraph}; use lightning::routing::utxo::UtxoLookup; use lightning::routing::router::{InFlightHtlcs, PaymentParameters, Route, RouteParameters, Router}; -use lightning::util::config::{UserConfig, MaxDustHTLCExposure}; +use lightning::util::config::UserConfig; use lightning::util::errors::APIError; use lightning::util::test_channel_signer::{TestChannelSigner, EnforcementState}; use lightning::util::logger::Logger; -use lightning::util::ser::{ReadableArgs, Writeable}; +use lightning::util::ser::{Readable, ReadableArgs, Writeable}; use crate::utils::test_logger; use crate::utils::test_persister::TestPersister; @@ -438,7 +438,17 @@ impl SignerProvider for KeyProvider { } #[inline] -pub fn do_test(data: &[u8], logger: &Arc) { +pub fn do_test(mut data: &[u8], logger: &Arc) { + if data.len() < 32 { return; } + + let our_network_key = match SecretKey::from_slice(&data[..32]) { + Ok(key) => key, + Err(e) => return, + }; + data = &data[32..]; + + let config: UserConfig = if let Ok(config) = Readable::read(&mut data) { config } else { return; }; + let input = Arc::new(InputData { data: data.to_vec(), read_pos: AtomicUsize::new(0), @@ -466,10 +476,6 @@ pub fn do_test(data: &[u8], logger: &Arc) { } } - let our_network_key = match SecretKey::from_slice(get_slice!(32)) { - Ok(key) => key, - Err(_) => return, - }; let inbound_payment_key = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 42]; @@ -483,10 +489,6 @@ pub fn do_test(data: &[u8], logger: &Arc) { counter: AtomicU64::new(0), signer_state: RefCell::new(HashMap::new()) }); - let mut config = UserConfig::default(); - config.channel_config.forwarding_fee_proportional_millionths = slice_to_be32(get_slice!(4)); - config.channel_config.max_dust_htlc_exposure = MaxDustHTLCExposure::FeeRateMultiplier(5_000_000 / 253); - config.channel_handshake_config.announced_channel = get_slice!(1)[0] != 0; let network = Network::Bitcoin; let best_block_timestamp = genesis_block(network).header.time; let params = ChainParameters { @@ -782,8 +784,7 @@ mod tests { // Writing new code generating transactions and see a new failure ?
