Delving Bitcoin discussion thread: https://delvingbitcoin.org/t/v3-transaction-policy-for-anti-pinning/340 Delving Bitcoin discussion for LN usage: https://delvingbitcoin.org/t/lightning-transactions-with-v3-and-ephemeral-anchors/418 Rationale: - There are various pinning problems with RBF and our general ancestor/descendant limits. These policies help mitigate many pinning attacks and make package RBF feasible (see #28984 which implements package RBF on top of this). I would focus the most here on Rule 3 pinning. [1][2] - Switching to a cluster-based mempool (see #27677 and #28676) requires the removal of CPFP carve out, which applications depend on. V3 + package RBF + ephemeral anchors + 1-parent-1-child package relay provides an intermediate solution. V3 policy is for "Priority Transactions." [3][4] It allows users to opt in to more restrictive topological limits for shared transactions, in exchange for the more robust fee-bumping abilities that offers. Even though we don't have cluster limits, we are able to treat these transactions as having as having a maximum cluster size of 2. Immediate benefits: - You can presign a transaction with 0 fees (not just 1sat/vB!) and add a fee-bump later. - Rule 3 pinning is reduced by a significant amount, since the attacker can only attach a maximum of 1000vB to your shared transaction. This also enables some other cool things (again see #27463 for overall roadmap): - Ephemeral Anchors - Package RBF for these 1-parent-1-child packages. That means e.g. a commitment tx + child can replace another commitment tx using the child's fees. - We can transition to a "single anchor" universe without worrying about package limit pinning. So current users of CPFP carve out would have something else to use. - We can switch to a cluster-based mempool [5] (#27677 #28676), which removes CPFP carve out [6]. [1]: Original mailing list post and discussion about RBF pinning problems https://gist.github.com/glozow/25d9662c52453bd08b4b4b1d3783b9ff, https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-January/019817.html [2]: A FAQ is "we need this for cluster mempool, but is this still necessary afterwards?" There are some pinning issues that are fixed here and not fully fixed in cluster mempool, so we will still want this or something similar afterward.

By relocating the peer desirable services flags into the peer manager, we allow the connections acceptance process to handle post-IBD potential stalling scenarios. The peer manager will be able to dynamically adjust the services flags based on the node's proximity to the tip (back and forth). Allowing the node to recover from the following post-IBD scenario: Suppose the node has successfully synced the chain, but later experienced dropped connections and remained inactive for a duration longer than the limited peers threshold (the timeframe within which limited peers can provide blocks). In such cases, upon reconnecting to the network, the node might only establish connections with limited peers, filling up all available outbound slots. Resulting in an inability to synchronize the chain (because limited peers will not provide blocks older than the `NODE_NETWORK_LIMITED_MIN_BLOCKS` threshold).

2024-01-15net: move state dependent peer services flagsfurszy
No behavior change. Just an intermediate refactoring. By relocating the peer desirable services flags into the peer manager, we allow the connections acceptance process to handle post-IBD potential stalling scenarios. In the follow-up commit(s), the desirable service flags will be dynamically adjusted to detect post-IBD stalling scenarios (such as a +48-hour inactive node that must prefer full node connections instead of limited peer connections because they cannot provide historical blocks). Additionally, this encapsulation enable us to customize the connections decision-making process based on new user's configurations in the future.

This gets rid of an unnecessary layer of indirection, and allows getting rid of the `kernel::g_context` global. Additionally, this PR tries to improve error handling of `SignalInterrupt` code by marking relevant methods `[[nodiscard]]` to avoid the possibility of uncaught exceptions mentioned https://github.com/bitcoin/bitcoin/pull/27861#discussion_r1255496707. Behavior is changing In a few cases which are noted in individual commit messages. Particularly: GUI code more consistently interrupts RPCs when it is shutting down, shutdown state no longer persists between unit tests, the stop RPC now returns an RPC error if requesting shutdown fails instead of aborting, and other failed shutdown calls now log errors instead of aborting. This PR is a net reduction in lines of code, but in some cases the explicit error handling and lack of global shutdown functions do make it more verbose. The verbosity can be seen as good thing if it discourages more code from directly triggering shutdowns, and instead encourages code to return errors or send notifications that could be translated into shutdowns. Probably a number of existing shutdown calls could just be replaced by better error handling.

This PR includes the following changes: - Added a new callback to the Validation Interface `MempoolTransactionsRemovedForConnectedBlock`, which notifies listeners about the transactions that have been removed due to a new block being connected, along with the height at which the transactions were removed. - Modified the `TransactionAddedToMempool` callback parameter to include additional information about the transaction needed for fee estimation. - Updated `CBlockPolicyEstimator` to process transactions using` CTransactionRef` instead of `CTxMempoolEntry.` - Implemented the `CValidationInterface` interface in `CBlockPolicyEstimater` and overridden the `TransactionAddedToMempool`, `TransactionRemovedFromMempool`, and `MempoolTransactionsRemovedForConnectedBlock` methods to receive updates from their notifications. Prior to this PR, the fee estimator updates from the mempool, i.e whenever a new block is connected all transactions in the block that are in our mempool are going to be removed using the `removeForBlock` function in `txmempool.cpp`. This removal triggered updates to the fee estimator. As a result, the fee estimator would block mempool's `cs` until it finished updating every time a new block was connected. Instead of being blocked only on mempool tx removal, we were blocking on both tx removal and fee estimator updating. If we want to further improve fee estimation, or add heavy-calulation steps to it, it is currently not viable as we would be slowing down block relay in the process This PR is smaller in terms of the changes made compared to #11775, as it focuses solely on enabling fee estimator updates from the validationInterface/cscheduler thread notifications. I have not split the validation interface because, as I understand it, the rationale behind the split in #11775 was to have `MempoolInterface` signals come from the mempool and `CValidationInterface` events come from validation. I believe this separation can be achieved in a separate refactoring PR when the need arises. Also left out some commits from #11775 - Some refactoring which are no longer needed. - Handle reorgs much better in fee estimator. - Track witness hash malleation in fee estimator I believe they are a separate change that can come in a follow-up after this.
