2022-08-01Merge bitcoin/bitcoin#24799: Add test case mimicking issue 24765MacroFake
395767e9f15b7a1b5203da68f1fbe3df281ae906 Add test case mimicking issue 24765 (Pieter Wuille) Pull request description: This adds a functional test for the concern brought up in #24765. It turned out to be a non-issue, but since I wrote it anyway, it can't hurt to add it. Top commit has no ACKs.

is set cccc1e70b8a14430cc94143da97936a60d6c83d3 Enforce Taproot script flags whenever WITNESS is set (MarcoFalke) fa422994116a7a053789304d56159760081479eb Remove nullptr check in GetBlockScriptFlags (MarcoFalke) faadc606c7644f2934de390e261d9d65a81a7592 refactor: Pass const reference instead of pointer to GetBlockScriptFlags (MarcoFalke) Pull request description: Now that Taproot is active, it makes sense to enforce its rules on all blocks, even historic ones, regardless of the deployment status. ### Benefits: (With "script flags" I mean "taproot script verification flags".) * Script flags are known ahead for all blocks (even blocks not yet created) and do not change. This may benefit static analysis, code review, and development of new script features that build on Taproot. * Any future bugs introduced in the deployment code won't have any effect on the script flags, as they are independent of deployment. * Enforcing the taproot rules regardless of the deployment status makes testing easier because invalid blocks after activation are also invalid before activation. So there is no need to differentiate the two cases. * It gives belt-and-suspenders protection against a practically expensive and theoretically impossible IBD reorg attack where the node is eclipsed. While `nMinimumChainWork` already protects against this, the cost for a few months worth of POW might be lowered until a major version release of Bitcoin Core reaches EOL. The needed work for the attack is the difference between `nMinimumChainWork` and the work at block 709632. For reference, previously the same was done for P2SH and WITNESS in commit 0a8b7b4b33c9d78574627fc606267e2d8955cd1c. ### Implementation: I found one block which fails verification with the flags applied, so I added a `TaprootException`, similar to the `BIP16Exception`. For reference, the debug log: ``` ERROR: ConnectBlock(): CheckInputScripts on b10c007c60e14f9d087e0291d4d0c7869697c6681d979c6639dbd960792b4d41 failed with non-mandatory-script-verify-flag (Witness program was passed an empty witness) BlockChecked: block hash=0000000000000000000f14c35b2d841e986ab5441de8c585d5ffe55ea1e395ad state=non-mandatory-script-verify-flag (Witness program was passed an empty witness) InvalidChainFound: invalid block=0000000000000000000f14c35b2d841e986ab5441de8c585d5ffe55ea1e395ad height=692261 log2_work=92.988459 date=2021-07-23T08:24:20Z InvalidChainFound: current best=0000000000000000000067b17a4c0ffd77c29941b15ad356ca8f980af137a25d height=692260 log2_work=92.988450 date=2021-07-23T07:47:31Z ERROR: ConnectTip: ConnectBlock 0000000000000000000f14c35b2d841e986ab5441de8c585d5ffe55ea1e395ad failed, non-mandatory-script-verify-flag (Witness program was passed an empty witness) ``` Hint for testing, make sure to set `-noassumevalid`. ### Considerations Obviously this change can lead to consensus splits on the network in light of massive reorgs. Currently the last block before Taproot activation, that is the last block without the Taproot script flags set, is only buried by a few days of POW. However, when and if this patch is included in the next major release, it will be buried by a few months of POW. BIP90 considerations apply when looking at reorgs this large.

fa3e0da06b491b8c0fa2dbae37682a9112c9deb8 policy: Treat taproot as always active (MarcoFalke) Pull request description: Now that taproot is active, it can be treated as if it was always active for policy for the next major release. This simplifies the code and changes two things: * Importing `tr` descriptors can be done before the chain is fully synced. This is fine, because the wallet will already generate `tr` descriptors by default (regardless of the taproot status) after commit 47fe7445e7f54aee10ec6dbc53f1db1adbeb43de. * Valid taproot spends won't be rejected from the mempool before taproot is active. This is strictly speaking a bugfix after commit 47fe7445e7f54aee10ec6dbc53f1db1adbeb43de, since the wallet may generate taproot spends before the chain is fully synced. For example, a slow node or a purposefully offline node. Currently, the wallet needs the mempool to account for change. See https://github.com/bitcoin/bitcoin/issues/11887. A similar change was done for segwit v0 in https://github.com/bitcoin/bitcoin/pull/13120 . This effectively reverts commit c5ec0367d718544caa3a1578d6c730fc92ee4e94.

2021-11-17test: refactor: take use of `create_block` txlist parameterSebastian Falbesoner
Passing a list of transactions `txlist` to `create_block` appends them to the block, hence we don't need to do that manually anymore. The merkle root calculation can also be removed, since this is done in the end of the helper.

2021-11-12tests: add deterministic signing mode to ECDSAPieter Wuille
This does the following: * Adds a rfc6979 argument to test_framework/key.py's sign_ecdsa to select (deterministic) RFC6979-based nonce generation. * Add a flag in feature_taproot.py's framework called "deterministic". * Make the Schnorr signing in feature_taproot.py randomized by default, reverting to the old deterministic (aux_rnd=0x0000...00) behavior if the deterministic context flag is set. * Make the ECDSA signing in feature_taproot.py use RFC6979-based nonces when the deterministic context flag is set (keeping the old randomized behavior otherwise).
