Matt Corallo 25542b8157 Always return failure in update_monitor after funding spend ... Previously, monitor updates were allowed freely even after a funding-spend transaction confirmed. This would allow a race condition where we could receive a payment (including the counterparty revoking their broadcasted state!) and accept it without recourse as long as the ChannelMonitor receives the block first, the full commitment update dance occurs after the block is connected, and before the ChannelManager receives the block. Obviously this is an incredibly contrived race given the counterparty would be risking their full channel balance for it, but its worth fixing nonetheless as it makes the potential ChannelMonitor states simpler to reason about. The test in this commit also tests the behavior changed in the previous commit.		2021-12-06 18:39:37 +00:00
