LSPS1: Add initial integration test

This commit adds a new automated integration test for the LSPS1 (Lightning Service Provider Specification 1) feature in the rust-lightning project. It does not change any production code, only test code. There is no security issue here.

Test manual broadcast tracking and holder commit flow

This commit only adds new tests and a test helper for the 'manual broadcast' funding flow in a Lightning network library. It does not change production behavior, fix a bug, or alter security-critical code. The tiny code change in channelmo…

Defer claimable tracking until funding tx confirms

This patch fixes a logic bug in rust-lightning's channel monitor for manually-broadcast funding transactions. Previously, the monitor could try to claim outputs and watch for spending transactions before the funding transaction had actuall…

Queue holder commit once funding tx confirms

This patch fixes a logic gap in Lightning Dev Kit's channel monitoring. When a user manually chooses not to broadcast their side of a new channel immediately, the code was supposed to queue that broadcast for once the funding transaction i…

Add manual-funding broadcast tracking to ChannelMonitor

This commit adds internal bookkeeping to LDK's channel monitor so it can tell whether a channel uses 'manual' funding-transaction broadcasts and whether that funding transaction has actually appeared on-chain yet. The goal is to stop the n…

Prevents premature holder commitment broadcasts for channels whose funding transaction is not yet on-chainAdds backward-compatible persistence for new channel-monitor stateDefensive fix for LSPS2 client_trusts_lsp=true scenario where LSP may defer funding broadcast

Gate holder broadcast queueing on funding confirmation

This change fixes a logic bug in Lightning Dev Kit's channel monitor. When a user manually broadcasts their own funding transaction (rather than letting LDK do it automatically), the software could previously try to broadcast a commitment …

Set funding_seen_onchain=true in filter_block

This commit fixes a bookkeeping flag in the Lightning channel monitor. The flag `funding_seen_onchain` was not being set when the funding transaction was observed on the blockchain, even though the code already detected it. Setting the fla…

Prefactor: drop #[rustfmt::skip] on broadcast_latest_holder_commitment_txn

This commit is purely a code formatting cleanup. It removes a `#[rustfmt::skip]` annotation and lets rustfmt reformat the `broadcast_latest_holder_commitment_txn` function. There is no change to program logic, behavior, or security.

Support client_trusts_lsp on LSPS2

This commit adds a new LSPS2 trust model called client_trusts_lsp. In this model, a Lightning Service Provider (LSP) delays broadcasting the Bitcoin funding transaction for a new channel until the client has actually paid the channel-openi…

Add LSPS5 DOS protections.

This commit adds a new access-control rule to the LSPS5 (webhook) service in rust-lightning. Before accepting a state-allocating LSPS5 request such as 'set webhook', the service now requires proof that the requesting peer is already 'engag…

[LSPS5] Change notification cooldown time to 1 minute, also update docs.

This commit changes the LSPS5 webhook notification cooldown from 1 hour to 1 minute. The shorter cooldown means the same type of notification can be sent to a client's webhooks far more frequently. This is not a code vulnerability in itsel…

Rate-limiting threshold relaxed by 60x (1 hour -> 1 minute)Webhook notification spam now easier due to shorter cooldownNo input validation or additional throttling added to compensate

Make LSPSDateTime Copy rather than explicitely _clone_ing

This commit is a small internal code cleanup. It makes a date/time wrapper type copyable by value instead of requiring an explicit clone, and removes a few now-unnecessary `.clone()` calls. There is no security-relevant change and no user-…
