v0.0.120

v0.0.120 - Jan 17, 2024 - "Unblinded Fuzzers"

API Updates

• The PeerManager bound on UtxoLookup was removed entirely. This enables
  use of UtxoLookup in cases broken in 0.0.119 by #2773 (#2822).
• LDK now exposes and fully implements the route blinding feature (#2812).
• The lightning-transaction-sync crate no longer relies on system time
  without the time feature (#2799, #2817).
• lightning::onion_message's module layout has changed (#2821).
• Event::ChannelClosed now includes the channel_funding_txo (#2800).
• CandidateRouteHop variants were destructured into individual structs,
  hiding some fields which were not generally consumable (#2802).

Bug Fixes

• Fixed a rare issue where lightning-net-tokio may not fully flush its send
  buffer, leading to connection hangs (#2832).
• Fixed a panic which may occur when connecting to a peer if we opened a second
  channel with that peer while they were disconnected (#2808).
• Retries for a payment which previously failed in a blinded path will now
  always use an alternative blinded path (#2818).
• Feature's Eq and Hash implementation now ignore dummy bytes (#2808).
• Some missing DiscardFunding or ChannelClosed events are now generated in
  rare funding-related failures (#2809).
• Fixed a privacy issue in blinded path generation where the real
  cltv_expiry_delta would be exposed to senders (#2831).

Security

0.0.120 fixes a denial-of-service vulnerability which is reachable from
untrusted input from peers if the UserConfig::manually_accept_inbound_channels
option is enabled.

• A peer that sent an open_channel message with the channel_type field
  unfilled would trigger a reachable unwrap since LDK 0.0.117 (#2808).
• In protocols where a funding output is shared with our counterparty before
  it is given to LDK, a malicious peer could have caused a reachable panic
  by reusing the same funding info in (#2809).
