Expand check-rip25-v48-invariants.sh to cover the contextual BIP9 script-flag wiring, 8/12/16 MWU block-weight phases, encrypted PQ wallet persistence, version-proven liboqs, the 4.8.0 KAWPOW and overflow protections, and CI supply-chain integrity. Remove the unpinned ds-store PyPI install and verify the macOS SDK checksum before extraction. --- .github/scripts/00-install-deps.sh | 5 +- .github/scripts/02-copy-build-dependencies.sh | 13 +- .github/scripts/06-package.sh | 5 +- .github/workflows/build-raven.yml | 161 +++++++------- .github/workflows/rip25-v48-final-gate.yml | 179 ++++------------ .../devtools/check-rip25-v48-invariants.sh | 197 ++++++++++++++---- 6 files changed, 272 insertions(+), 288 deletions(-) diff --git a/.github/scripts/00-install-deps.sh b/.github/scripts/00-install-deps.sh index 599ad5e1cb..6ec7e5f427 100755 --- a/.github/scripts/00-install-deps.sh +++ b/.github/scripts/00-install-deps.sh @@ -64,10 +64,7 @@ elif [[ ${OS} == "osx" ]]; then s3curl \ sleuthkit \ bison \ - libtinfo5 \ - python3-pip - - pip3 install ds-store + libtinfo5 elif [[ ${OS} == "linux" || ${OS} == "linux-disable-wallet" || ${OS} == "aarch64" || ${OS} == "aarch64-disable-wallet" ]]; then apt -y install \ diff --git a/.github/scripts/02-copy-build-dependencies.sh b/.github/scripts/02-copy-build-dependencies.sh index 1a0672c9d3..44c23d9e26 100755 --- a/.github/scripts/02-copy-build-dependencies.sh +++ b/.github/scripts/02-copy-build-dependencies.sh @@ -1,5 +1,7 @@ #!/usr/bin/env bash +set -euo pipefail + OS=${1} GITHUB_WORKSPACE=${2} GITHUB_REF=${3} @@ -25,11 +27,14 @@ cd depends if [[ ${OS} == "windows" ]]; then make HOST=x86_64-w64-mingw32 -j2 elif [[ ${OS} == "osx" ]]; then - mkdir SDKs + SDK_ARCHIVE=Xcode-11.3.1-11C505-extracted-SDK-with-libcxx-headers.tar.gz + SDK_SHA256=436df6dfc7073365d12f8ef6c1fdb060777c720602cc67c2dcf9a59d94290e38 + mkdir -p SDKs cd SDKs - curl -O https://bitcoincore.org/depends-sources/sdks/Xcode-11.3.1-11C505-extracted-SDK-with-libcxx-headers.tar.gz - tar -zxf Xcode-11.3.1-11C505-extracted-SDK-with-libcxx-headers.tar.gz - rm -rf Xcode-11.3.1-11C505-extracted-SDK-with-libcxx-headers.tar.gz + curl --fail --location --retry 3 --output "${SDK_ARCHIVE}" "https://bitcoincore.org/depends-sources/sdks/${SDK_ARCHIVE}" + echo "${SDK_SHA256} ${SDK_ARCHIVE}" | sha256sum --check + tar -zxf "${SDK_ARCHIVE}" + rm -f "${SDK_ARCHIVE}" cd .. make HOST=x86_64-apple-darwin14 -j2 elif [[ ${OS} == "linux" || ${OS} == "linux-disable-wallet" ]]; then diff --git a/.github/scripts/06-package.sh b/.github/scripts/06-package.sh index 85230c207c..989a4e30e9 100755 --- a/.github/scripts/06-package.sh +++ b/.github/scripts/06-package.sh @@ -1,12 +1,11 @@ #!/usr/bin/env bash +set -euo pipefail + OS=${1} GITHUB_WORKSPACE=${2} GITHUB_BASE_REF=${3} -echo "----------------------------------------" -env -echo "----------------------------------------" if [[ ! ${OS} || ! ${GITHUB_WORKSPACE} || ! ${GITHUB_BASE_REF} ]]; then echo "Error: Invalid options" diff --git a/.github/workflows/build-raven.yml b/.github/workflows/build-raven.yml index 1a8aae570d..36dec5fa2a 100644 --- a/.github/workflows/build-raven.yml +++ b/.github/workflows/build-raven.yml @@ -1,65 +1,26 @@ name: Build Raven on: -# push: -# branches: -# - release* -# pull_request: -# branches: -# - master -# - develop -# - release* -# paths-ignore: -# - 'binaries/**' -# - 'doc/**' -# - 'whitepaper/**' -# - '*.md' + push: + branches: + - fix/rip25-v48-glm-remediation workflow_dispatch: - # This creates a "Run workflow" button on the github repo webpage when the "Build Ravencoin" - # workflow is selected on the "Actions" tab.

Policy restricts the stack shape but does not + cryptographically validate it. Existing cleanup handles ACTIVE-to-preactive + rollback only; no forward transition revalidates existing spends under + `SCRIPT_VERIFY_PQ_HYBRID`. +- **Affected file/function/lines:** `src/script/interpreter.cpp:1535-1599`, + `VerifyWitnessProgram`; `src/policy/policy.cpp:260-321`, + `IsWitnessStandard`; `src/validation.cpp:544-556,897-925`, admission; + `src/txmempool.cpp:790-845`, `CTxMemPool::removeForReorg`; normal connect + transition at `src/validation.cpp:3487-3495`. +- **Introducing commit:** The future-witness behavior is inherited SegWit + consensus and required for soft-fork compatibility. Approved PR #1281 added + the witness-v2 rule but no forward mempool sanitation; integration commit + `28f6bbf2c` made admission contextual and remediation `7168bf6b68` added only + rollback cleanup. The gap therefore affects the approved architecture and + remains incomplete in this integration. +- **Concrete exploit/divergence:** Spend an existing native or P2SH-wrapped + v2/32-byte UTXO during LOCKED_IN with two in-range but invalid ML-DSA elements + and a high fee. It is admitted as a future witness. At ACTIVE it remains in + mempool; block assembly selects it, final validation rejects the PQ signature, + and the built-in miner stops on the first template exception. A stockpile + repeatedly poisons GBT even if one identified transaction is evicted per call. + Cached sigops are also stale as described in FINDING-014. +- **Expected correct behavior:** On the exact false-to-true transition, every + retained v2 spend is revalidated with the active PQ flag; failures and all + descendants are removed before any template is exposed. Valid preactivation + spends may remain only if their ML-DSA material is valid under ACTIVE. +- **Proposed remediation:** Add a unified activation-transition mempool + sanitation pass using a mempool-backed UTXO view and active script flags; + recursively purge invalid spends and refresh or independently recompute + contextual sigop accounting. +- **Regression required:** Native and P2SH invalid/valid v2 spends admitted + preactivation, direct activation and alternate-fork/invalidate/reconsider + transitions, descendants/unrelated entries, and non-throwing miner/GBT + output after sanitation. +- **Remediation commit:** PENDING +- **Final status:** OPEN + +The unresolved HIGH list is extended by FINDING-024; the second-audit verdict +remains **FAIL**.

The function therefore reports success to + `EncryptKeys` even when plaintext removal failed. +- **Affected file/function/lines:** `src/wallet/walletdb.cpp:75-89`, + `CWalletDB::WriteCryptedKey`, especially the unchecked `EraseIC` calls at + `:86-87`; reached from `CWallet::AddCryptedKey` and + `CCryptoKeyStore::EncryptKeys`. +- **Introducing commit/provenance:** The unchecked calls descend from the + initial Ravencoin Bitcoin fork commit `aab4e5b6a5` and are byte-identical in + the official Core 4.8.0 snapshot `b60f50e0`. This is a bug already present + in **Core 4.8.0**, not a RIP-25 integration regression. +- **Concrete exploit/divergence:** If Berkeley DB accepts the ciphertext write + but returns an error while deleting an existing plaintext key, wallet + encryption continues toward commit and compaction as though conversion were + complete. The database can retain both `ckey` and recoverable plaintext + private-key material; mixed records can also make a later load fail after + the user was told that encryption succeeded. The trigger requires a local + storage/lock/resource failure, but the impact is private-key disclosure and + possible wallet unavailability. +- **Expected correct behavior:** Missing old records are harmless, but every + other delete error aborts the encryption transaction. Standalone encrypted + writes roll back the new ciphertext/in-memory entry on persistence failure; + encrypted load and backup reject any remaining plaintext private-key record. +- **Proposed remediation:** Propagate both erase results (where `DB_NOTFOUND` + remains success), best-effort remove a just-written `ckey` on failure, make + `CWallet::AddCryptedKey` restore its previous in-memory map entry, and extend + the ciphertext-only loader/backup scan from PQ records to ordinary + `key`/`wkey` records. +- **Regression required:** A dummy database whose writes succeed and erases + fail must make `WriteCryptedKey` return false; an injected persistence + failure must restore in-memory state; a real database containing `mkey` or + `ckey` plus `key`/`wkey` must fail encrypted load and backup; normal + encryption/reload/backup must remain ciphertext-only. +- **Remediation commit:** PENDING +- **Final status:** OPEN + +FINDING-031 extends the unresolved HIGH list.

Security Consequence + +A cryptographically relevant quantum computer that recovers a secp256k1 private key can steal an asset UTXO even if the same wallet also holds native RVN at RIP-25 addresses. Theft of `ASSET!` is especially serious because it can transfer administrative control and authorize reissuance when the asset is reissuable. Unique assets can be transferred irreversibly. Restricted and qualifier administration remains exposed through its legacy authorization outputs. + +Wallet and RPC messages must not imply that generating a PQ address protects asset owner or administrator tokens. The immediate implementation guard rejects unsupported asset destinations before it constructs an invalid transaction. + +## 3. Why the Proposed Concatenation Is Unsafe + +One conceptual form suggested for future analysis is: + +``` +OP_2 <32-byte-hash> OP_RVN_ASSET OP_DROP +``` + +It must not be adopted directly. + +First, a native witness program must be the entire script. Adding any suffix makes `CScript::IsWitnessProgram` return false. Second, the current asset parser requires the asset opcode at the P2PKH-specific byte offset. Third, `OP_RVN_ASSET` is a no-op in ordinary script execution. Merely teaching the asset parser to recognize the proposed concatenation would not invoke witness-v2 verification and could create an anyone-can-spend asset output. + +Current nodes reject the form because the asset opcode appears in the wrong location. Changing it from invalid to valid expands the set of valid transactions. The deployment and legacy-node consequences therefore require a complete fork analysis and cannot be assumed to form a conventional soft fork. + +## 4. Required Protocol Design + +A follow-up proposal should define a canonical versioned asset envelope that separates: + +1. the ownership or spending-condition version; +2. the asset operation type; +3. the serialized asset payload. + +The spending condition must unambiguously dispatch to ML-DSA-44 witness-v2 verification. It must not depend on a parser side effect or on executing `OP_RVN_ASSET` as an opcode. The proposal must specify exact serialization lengths, canonical pushes, rejection of trailing data, and how unknown versions behave. + +At minimum, the consensus design must cover: + +- normal issue and transfer operations; +- owner-token creation and transfer; +- reissue authorization; +- unique-asset creation and transfer; +- restricted-asset issue, transfer, reissue, freeze, and verifier behavior; +- qualifier and sub-qualifier issue, transfer, tag, and untag behavior; +- asset input and output overflow checks from Ravencoin Core 4.8.0; +- fixed RIP-25 SIGHASH policy; +- ML-DSA network context and cross-network replay resistance; +- PQ sigop-equivalent accounting; +- contextual witness discount and block-weight accounting; +- activation boundaries and reorgs. + +## 5. Recognition and Script Ambiguity + +The design must replace fixed-offset assumptions with a parser that accepts exactly the intended legacy and activated PQ forms. It must prove that: + +- no legacy script changes meaning; +- no script is accepted by both legacy and PQ parsers with different destinations or asset payloads; +- no malformed PQ form falls through to ordinary script execution; +- unknown ownership versions fail closed after activation; +- `IsAssetScript`, `Solver`, destination extraction, and transaction classifiers agree; +- null asset data cannot be confused with spendable asset ownership. + +Parser tests need canonical and non-canonical encodings, shortened and extended programs, misplaced opcodes, extra stack elements, trailing bytes, and payload length boundaries. + +## 6. Legacy-Node and Activation Analysis + +The proposal must state how an unupgraded node evaluates each new output and spend. If an old node treats the new form as spendable without ML-DSA verification, activation must ensure upgraded miners and validators reject unauthorized spends. If old nodes reject the new output form, deployment has hard-fork characteristics and must be treated accordingly. + +The activation design must include: + +- a dedicated deployment or an explicitly justified reuse of a deployment state; +- pre-activation policy and consensus behavior; +- `DEFINED`, `STARTED`, `LOCKED_IN`, and `ACTIVE` transitions; +- activation-height minus two through activation-height plus two vectors; +- invalidate and reconsider behavior; +- reorgs across `LOCKED_IN` and `ACTIVE`; +- versionbits cache invalidation and restart behavior; +- miner-template and validator equivalence. + +No asset extension should be coupled silently to an already deployed RIP-25 bit. + +## 7. Wallet, RPC, and Address Encoding + +The wallet needs an explicit PQ asset destination type rather than reusing a native-RVN address without a defined asset meaning. The design must decide whether the same witness-v2 address can represent both native RVN and asset ownership or whether a distinct encoding is safer. + +Required wallet behavior includes: + +- PQ asset ownership detection and balance attribution; +- ML-DSA signing for every asset spend path; +- PQ asset change selection; +- owner-token and reissue authorization; +- coin control and fee estimation for large witnesses; +- encrypted key persistence and recovery; +- watch-only and multisig policy, if supported; +- import, export, backup, restore, rescan, and salvage behavior; +- explicit errors on unsupported mixed legacy and PQ constructions. + +All high-level and raw-transaction RPCs must construct only canonical activated forms. RPC acceptance must not be treated as proof of consensus validity. + +## 8. Asset Index and Database Compatibility + +Asset indexes currently derive an address identity from legacy 20-byte data. A PQ program is 32 bytes. The follow-up design must version index keys or otherwise prevent truncation and type confusion. + +It must specify: + +- address-index key format; +- asset cache and database serialization versions; +- reindex and downgrade behavior; +- explorer and RPC address rendering; +- restricted and qualifier database keys; +- mempool overlay behavior; +- database rebuild after chainstate recovery. + +Database readers must reject malformed or unknown key versions without interpreting them as legacy records. + +## 9. Owner-Token Migration + +Existing `ASSET!` outputs cannot become quantum-resistant merely because RIP-25 activates. A migration mechanism must prove current authorization while moving control to a PQ asset condition. Design choices include a normal legacy-authorized transfer into the new condition or a dedicated migration transaction type. + +The proposal must address: + +- migration of owner tokens before a quantum emergency; +- reissuable assets whose owner token is lost or stolen; +- unique and restricted asset control; +- partial wallet migration and mixed legacy/PQ holdings; +- replay of migration transactions across networks; +- rescan and restore discovery; +- whether migration can be reversed; +- emergency behavior without creating a confiscation or inflation path. + +There is no safe automatic migration after the classical private key has been compromised. + +## 10. Mempool and Resource Policy + +Policy must bound attacker-controlled input before expensive ML-DSA verification. It must apply exact public-key and signature sizes, exact witness stack shape, canonical asset serialization, transaction-size limits, ancestor and descendant policy, orphan limits, and explicit PQ sigop-equivalent accounting. + +Consensus and policy limits must remain distinct. Policy may reject more than consensus, but miners and validators must calculate the same activated consensus cost for a block. + +## 11. Required Validation Matrix + +The follow-up implementation should not be proposed for activation without: + +- consensus `tx_valid` and `tx_invalid` vectors for every asset class; +- correct and incorrect ML-DSA signature vectors; +- script ambiguity and parser differential tests; +- cross-network replay tests; +- activation and reorg tests; +- miner-template versus block-validation tests; +- asset input/output overflow regression tests; +- wallet encrypted-backup recovery tests; +- address-index and reindex tests; +- P2P, orphan, mempool, and block resource tests; +- real-verifier fuzzing under ASan and UBSan; +- cross-platform deterministic validation builds. + +## 12. Current Decision + +The current RIP-25 remediation deliberately does not implement a PQ asset consensus extension. It documents assets as out of scope, rejects witness-v2 destinations in asset construction paths, and preserves the existing consensus rules. A separate RIP and independent adversarial review are required for any future PQ asset design. diff --git a/doc/RIP-0025-PQ-Signatures.md b/doc/RIP-0025-PQ-Signatures.md index d06ae0f1a2..270b370629 100644 --- a/doc/RIP-0025-PQ-Signatures.md +++ b/doc/RIP-0025-PQ-Signatures.md @@ -14,7 +14,7 @@ License: MIT ## Abstract -This RIP proposes adding **ML-DSA-44** (FIPS 204) as a post-quantum digital signature scheme to Ravencoin via a new **witness version 2** program.
