Handle missing splice tx_signatures on reestablish

This commit fixes a bug in LDK's Lightning channel reconnection logic after a splice (a way to resize a channel's on-chain funds). If one peer had already received the splice signatures but the other had not, and then they disconnected and…

Ignore stale splice initial commitment_signed

This patch fixes a bug in the Lightning Dev Kit where a delayed message from a peer could accidentally force-close a live payment channel. During a failed 'splice' (a way to resize a channel), the peer might already have sent a signature f…

Support async signing of splice shared input

This commit adds support for asynchronous signing of the shared input in a Lightning channel splice. Previously, the signature for the 2-of-2 multisig input had to be produced immediately when requested, which could block users whose signi…

Release tx_signatures after async monitor update completes

This commit fixes a bug in the Lightning Dev Kit where, during a special channel operation called splicing, the node could release its signatures for the new funding transaction before the local channel monitor had durably saved the counte…

Support async signing in chanmon_consistency

This commit only changes test and fuzzing code. It adds new test controls that let developers temporarily disable or enable individual signer operations during fuzz testing, and it removes one unused signer-operation flag. There is no chan…

Support async signing of interactive-tx initial commitment signatures

This commit adds support for asynchronous (delayed) signing when opening or splicing Lightning channels that use the newer interactive-funding protocol. Previously, if a hardware or remote signer was not ready to produce the initial commit…

Protocol-ordering fix: prevents sending tx_signatures before commitment_signed is availableAsync signer support extended to V2/interactive-tx funding and splicesRemoval of TODO comment indicating previously unimplemented dual-funding async signing path

This commit only changes test code in the Lightning Dev Kit Rust repository. It extends the test helper that simulates two Lightning nodes reconnecting after a disconnection so it can now capture and optionally re-send 'announcement_signat…

Sign splice shared input when producing holder tx_signatures

This commit fixes a missing signature in the Lightning splicing feature. When a user and their peer splice a channel (replace the old funding transaction with a new one), the old funding output is spent as a shared input in the new transac…

Assume splicing input value from channel parameters

This commit changes how a Bitcoin Lightning channel signer calculates the value of the old funding output when signing a splice transaction. Instead of accepting the value as a caller-provided argument, it now derives the value from the ch…
