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).
