From 7510de8f99fc13584efe6b77b439ad7803ecbefb Mon Sep 17 00:00:00 2001 From: Edgar Luque Date: Thu, 23 Apr 2026 13:59:02 +0200 Subject: [PATCH 01/48] feat(l1): support bal-devnet-4 (bal@v5.7.0) Brings ethrex up to bal-devnet-4 fixture spec. Rolls up EIP-7928, EIP-8037, EIP-7976, EIP-7981, EIP-7708 and misc BAL validation fixes into one change set. BAL (EIP-7928) - Widen BlockAccessIndex and related recorder/index fields to u32. - Shadow BAL recorder on per-tx tx_dbs in the parallel validator: diff touched_addresses / storage_reads against header BAL to catch missing pure-access entries and missing storage_reads. - Fall back to pre-state code_hash in validate_tx_execution PART B when the BAL has no code_changes entry (missing_code_change). - Stop whitelisting SYSTEM_ADDRESS from unaccessed_pure_accounts via system_seed / current_accounts_state scrubs; user-tx touches still remove it via the per-tx tracked_accounts path. EIP-8037 (state gas 2D accounting) - Dynamic cost_per_state_byte(block_gas_limit), Amsterdam only. - Two-counter reservoir: state_gas_spill_outstanding + state_gas_credit_against_drain for correct revert math across nested sub-calls (PR #2733 clamp-and-spill). - Per-tx 2D inclusion check (PR #2703) in sequential + parallel paths: reject with GAS_ALLOWANCE_EXCEEDED when tx.gas worst-case exceeds remaining block regular/state budget. - intrinsic_state_gas immutable across the tx (PR #2711) and subtracted separately when deriving block-dimensional regular gas. - CREATE collision/early/child failure refunds account state gas. - Same-tx SELFDESTRUCT refunds state gas clamped against execution-only state gas (PR #2707), not total state_gas_used. - Revert-path reservoir refill uses the PR #2733 X - Z formula. - Top-level reservoir reset on tx failure (PR #2689). - Zero gas_remaining on precompile exceptional halt so block accounting sees the full intrinsic. Calldata / access-list floors - TOTAL_COST_FLOOR_PER_TOKEN 10 -> 16 under Amsterdam (EIP-7976). - Access-list data bytes fold into floor-token count (EIP-7981). EIP-7708 - Lex-ordered burn logs, no coinbase priority-fee log, SELFDESTRUCT- destination coalescing. Tests - New levm tests for EIP-7976/7981, EIP-8037 refund/code-deposit/ top-level-failure paths. - Skip 6 zkevm@v0.3.0 EIP-8025 fixtures filled against bal@v5.6.1 (re-enable once zkevm@v0.4.x ships). Hive consume-engine amsterdam: 1339 pass, 3 remaining (withdrawal missing-entry cases addressed by PR #6463, cherry-pick pending). --- .github/config/hive/amsterdam.yaml | 6 +- Makefile | 4 +- crates/blockchain/constants.rs | 7 + crates/blockchain/mempool.rs | 18 +- crates/blockchain/payload.rs | 8 +- crates/common/errors.rs | 2 +- crates/common/types/block_access_list.rs | 99 ++- crates/common/validation.rs | 10 +- .../block_producer/payload_builder.rs | 4 +- crates/vm/backends/levm/mod.rs | 291 ++++++-- crates/vm/backends/mod.rs | 4 +- crates/vm/levm/src/call_frame.rs | 27 + crates/vm/levm/src/db/gen_db.rs | 4 +- crates/vm/levm/src/environment.rs | 4 + crates/vm/levm/src/execution_handlers.rs | 4 +- crates/vm/levm/src/gas_cost.rs | 70 +- crates/vm/levm/src/hooks/default_hook.rs | 172 ++++- .../stack_memory_storage_flow.rs | 28 +- crates/vm/levm/src/opcode_handlers/system.rs | 158 ++-- crates/vm/levm/src/utils.rs | 202 +++++- crates/vm/levm/src/vm.rs | 239 +++++- docs/developers/l1/testing/hive.md | 10 +- test/tests/levm/eip7708_tests.rs | 317 +++++++- test/tests/levm/eip7928_tests.rs | 46 +- test/tests/levm/eip7976_7981_tests.rs | 361 ++++++++++ test/tests/levm/eip8037_code_deposit_tests.rs | 622 ++++++++++++++++ test/tests/levm/eip8037_refund_tests.rs | 593 +++++++++++++++ test/tests/levm/eip8037_tests.rs | 34 + .../levm/eip8037_top_level_failure_tests.rs | 681 ++++++++++++++++++ test/tests/levm/l2_fee_token_tests.rs | 1 + test/tests/levm/l2_gas_reservation_tests.rs | 1 + test/tests/levm/l2_hook_tests.rs | 3 + test/tests/levm/mod.rs | 5 + .../blockchain/.fixtures_url_amsterdam | 2 +- tooling/ef_tests/blockchain/tests/all.rs | 12 + .../ef_tests/state/.fixtures_url_amsterdam | 2 +- 36 files changed, 3803 insertions(+), 248 deletions(-) create mode 100644 test/tests/levm/eip7976_7981_tests.rs create mode 100644 test/tests/levm/eip8037_code_deposit_tests.rs create mode 100644 test/tests/levm/eip8037_refund_tests.rs create mode 100644 test/tests/levm/eip8037_tests.rs create mode 100644 test/tests/levm/eip8037_top_level_failure_tests.rs diff --git a/.github/config/hive/amsterdam.yaml b/.github/config/hive/amsterdam.yaml index 1e48471197b..09b012eefbc 100644 --- a/.github/config/hive/amsterdam.yaml +++ b/.github/config/hive/amsterdam.yaml @@ -1,4 +1,4 @@ # Amsterdam (BAL) hive test configuration -# Pinned from ethereum/execution-specs devnets/bal/3 @ 2026-04-14 -fixtures: https://github.com/ethereum/execution-spec-tests/releases/download/bal@v5.6.1/fixtures_bal.tar.gz -eels_commit: 5c6e20abf3586f52d9e58393203ca07f2d0151fe +# Pinned from ethereum/execution-specs devnets/bal/4 @ 2026-04-21 +fixtures: https://github.com/ethereum/execution-spec-tests/releases/download/bal@v5.7.0/fixtures_bal.tar.gz +eels_commit: 524b44617e410ab21b5122f0be5113b62a0e76ee diff --git a/Makefile b/Makefile index 059c814c4a1..9e99b83452e 100644 --- a/Makefile +++ b/Makefile @@ -148,8 +148,8 @@ run-hive-eels-rlp: ## Run hive EELS RLP tests run-hive-eels-blobs: ## Run hive EELS Blobs tests $(MAKE) run-hive-eels EELS_SIM=ethereum/eels/execute-blobs -AMSTERDAM_FIXTURES_URL ?= https://github.com/ethereum/execution-spec-tests/releases/download/bal@v5.6.1/fixtures_bal.tar.gz -AMSTERDAM_FIXTURES_BRANCH ?= devnets/bal/3 +AMSTERDAM_FIXTURES_URL ?= https://github.com/ethereum/execution-spec-tests/releases/download/bal@v5.7.0/fixtures_bal.tar.gz +AMSTERDAM_FIXTURES_BRANCH ?= devnets/bal/4 run-hive-eels-amsterdam: build-image setup-hive ## πŸ§ͺ Run hive EELS Amsterdam Engine tests - cd hive && ./hive --client-file $(HIVE_CLIENT_FILE) --client ethrex --sim ethereum/eels/consume-engine --sim.limit ".*fork_Amsterdam.*" --sim.parallelism $(SIM_PARALLELISM) --sim.loglevel $(SIM_LOG_LEVEL) --sim.buildarg fixtures=$(AMSTERDAM_FIXTURES_URL) --sim.buildarg branch=$(AMSTERDAM_FIXTURES_BRANCH) diff --git a/crates/blockchain/constants.rs b/crates/blockchain/constants.rs index 733cd7f06be..62821995d7b 100644 --- a/crates/blockchain/constants.rs +++ b/crates/blockchain/constants.rs @@ -52,3 +52,10 @@ pub const MIN_GAS_LIMIT: u64 = 5000;

Three builder-side paths could produce blocks the validator rejects, plus minor hardening. - Mempool intrinsic gas was using `TX_CREATE_GAS_COST = 53000` unconditionally for CREATE. Under Amsterdam the VM charges the `(regular, state)` split derived from `intrinsic_gas_dimensions` (`REGULAR_GAS_CREATE + STATE_BYTES_PER_NEW_ACCOUNT * cpsb`). Route through the shared helper for Amsterdam+ so admission matches VM charge. - Payload builder (`fill_transactions`) had no EIP-8037 PR #2703 per-tx 2D inclusion check. A tx passing execution in the builder could still fail the check in the validator's aggregation loop and invalidate the block. Expose `check_2d_gas_allowance` as pub and call it before any BAL touches so rejected txs contribute nothing. - L2 payload builder recorded sender/recipient BAL touches before executing, with no checkpoint/restore for the `undo_last_tx` path (invalid L2 out-message) or apply-tx error. Mirror the L1 builder: take a `bal_checkpoint` after `set_bal_index`, restore on both rejection paths. - `execute_block_parallel` now computes `is_amsterdam` locally and explicitly gates the 2D inclusion loop, keeping the Amsterdam-only invariant checkable rather than implicit in the caller. - `check_2d_gas_allowance` doc now explains why our `block_regular_gas_used` aggregates `max(raw_regular, floor)` at tx-report time (matching EELS `block_output.block_gas_used`). - Post-exec 2D overflow rollback in `apply_plain_transaction` replaces the unchecked `-=` on `cumulative_gas_spent` with `saturating_sub` + `debug_assert`. - Missing-code-change per-tx BAL validation: when a BAL account has no `code_changes` entry (`seeded_pos == 0`), fall back to the `system_seed` / store pre-state code_hash. Fixes the remaining `missing_code_change` Hive test. Hive consume-engine amsterdam: 1340 pass, 2 remaining (withdrawal missing-entry cases addressed by PR #6463). --- crates/blockchain/mempool.rs | 33 +++++++++-------- crates/blockchain/payload.rs | 37 +++++++++++++++++-- .../block_producer/payload_builder.rs | 24 ++++++++++++ crates/vm/backends/levm/mod.rs | 33 +++++++++++++---- crates/vm/lib.rs | 6 +++ 5 files changed, 107 insertions(+), 26 deletions(-) diff --git a/crates/blockchain/mempool.rs b/crates/blockchain/mempool.rs index 09322b29c09..3b7071824f1 100644 --- a/crates/blockchain/mempool.rs +++ b/crates/blockchain/mempool.rs @@ -7,10 +7,9 @@ use rustc_hash::{FxHashMap, FxHashSet}; use crate::{ constants::{ - TX_ACCESS_LIST_ADDRESS_DATA_GAS_AMSTERDAM, TX_ACCESS_LIST_ADDRESS_GAS, - TX_ACCESS_LIST_STORAGE_KEY_DATA_GAS_AMSTERDAM, TX_ACCESS_LIST_STORAGE_KEY_GAS, - TX_CREATE_GAS_COST, TX_DATA_NON_ZERO_GAS, TX_DATA_NON_ZERO_GAS_EIP2028, - TX_DATA_ZERO_GAS_COST, TX_GAS_COST, TX_INIT_CODE_WORD_GAS_COST, + TX_ACCESS_LIST_ADDRESS_GAS, TX_ACCESS_LIST_STORAGE_KEY_GAS, TX_CREATE_GAS_COST, + TX_DATA_NON_ZERO_GAS, TX_DATA_NON_ZERO_GAS_EIP2028, TX_DATA_ZERO_GAS_COST, TX_GAS_COST, + TX_INIT_CODE_WORD_GAS_COST, }, error::MempoolError, }; @@ -22,6 +21,7 @@ use ethrex_common::{ }, }; use ethrex_storage::error::StoreError; +use ethrex_vm::intrinsic_gas_dimensions; use tracing::warn; #[derive(Debug, Default)] @@ -513,6 +513,20 @@ pub fn transaction_intrinsic_gas( header: &BlockHeader, config: &ChainConfig, ) -> Result { + // Amsterdam (EIP-8037): the VM splits intrinsic into (regular, state) and uses + // `REGULAR_GAS_CREATE = 9000` + `STATE_BYTES_PER_NEW_ACCOUNT * cpsb` for CREATE + // instead of the legacy `TX_CREATE_GAS_COST = 53000`.

Both paths share the VM core but diverge in plumbing (mempool admission, shadow BAL recorder, 2D inclusion check, BAL checkpoint/restore, coinbase and SYSTEM_ADDRESS filters), and a disagreement means a missed slot on devnet that a green ef-tests run cannot catch β€” ef-tests only consume blocks, never produce them. Two groups of tests: Positive parity (9). Builder produces a legitimate block, validator pipeline (parallel, BAL-seeded) must accept. Covers: empty block with only pre-exec system calls; plain transfer; CREATE tx (Amsterdam intrinsic split); SSTORE state gas; BALANCE of untouched account (pure-access BAL entry); calldata floor (EIP-7976); access-list floor (EIP-7981); user-tx touch of SYSTEM_ADDRESS; multi-tx multi-sender aggregation. Negative parity (5). Builder produces a legitimate block, the test corrupts the BAL (drops / mutates / appends entries), re-hashes the header, and the validator must reject. Each scenario mirrors one of the Hive test_bal_invalid_* cases fixed in session 3: parity_reject_missing_pure_access_account parity_reject_surplus_system_address parity_reject_missing_storage_read parity_reject_missing_storage_change parity_reject_missing_code_change If one of the negative tests ever flips to "accept" the corresponding BAL-validation check has regressed; treat as P0. --- .../builder_validator_parity_tests.rs | 1082 +++++++++++++++++ test/tests/blockchain/mod.rs | 1 + 2 files changed, 1083 insertions(+) create mode 100644 test/tests/blockchain/builder_validator_parity_tests.rs diff --git a/test/tests/blockchain/builder_validator_parity_tests.rs b/test/tests/blockchain/builder_validator_parity_tests.rs new file mode 100644 index 00000000000..ecfd1d3fa08 --- /dev/null +++ b/test/tests/blockchain/builder_validator_parity_tests.rs @@ -0,0 +1,1082 @@ +//! Builder / validator parity tests for Amsterdam (EIP-7928 + EIP-8037). +//! +//! # Why this module exists +//! +//! When ethrex produces a block as a builder and that same block is later +//! executed by ethrex as a validator (or by any EELS-compatible validator), +//! both code paths **must** reach bit-identical conclusions on: +//! +//! - the final state root, +//! - the receipts root, +//! - the block-level gas accounting (`max(block_regular_gas_used, block_state_gas_used)`), +//! - the contents and hash of the Block Access List. +//! +//! If they disagree, the builder-produced block will be rejected at inclusion, +//! the slot is missed, and the validator loses its proposer reward. This is a +//! correctness-critical class of bug: it can only be triggered against live +//! traffic, it's silent in any single-path test, and a single missed slot can +//! costs more than a regression test ever will. +//! +//! The Amsterdam rollup (EIP-7928 Block Access Lists, EIP-8037 two-dimensional +//! state gas, EIP-7976/7981 calldata & access-list floors, EIP-7708 transfer +//! logs) introduced a large surface area where the two paths diverge in +//! plumbing even though they share the same VM core. Notable risk areas: +//! +//! - Mempool admission gas checks that must match VM intrinsic charges exactly, +//! so the builder never admits a tx the VM would later reject, and never +//! rejects a tx the VM would accept (EIP-8037 CREATE intrinsic split). +//! - BAL recording sites vs. BAL validation sites β€” the builder records via +//! `bal_recorder` callsites (gated on post-gas-check conditions); the +//! validator runs a shadow recorder on per-tx `tx_db` and diffs against the +//! header BAL. +//! - The 2D inclusion check (EIP-8037 PR #2703) must fire at the same running +//! totals on the builder (`fill_transactions`) and the validator +//! (`execute_block_parallel` aggregation loop). +//! - Net-zero balance / storage filtering, coinbase handling when priority fee +//! is zero, SYSTEM_ADDRESS filtering for pre-exec system calls vs. user-tx +//! accesses. +//! - State-gas reservoir semantics across revert / success: the builder +//! maintains a `bal_checkpoint` across rejected txs; the validator maintains +//! an equivalent snapshot per frame. +//! +//! # How a test fails +//! +//! Each test seeds an Amsterdam-at-genesis chain, puts one or more txs into the +//! mempool, drives the payload builder to produce a block, and then hands the +//! result (block + BAL) back to the validator pipeline via +//! `add_block_pipeline_bal`. A failure therefore surfaces as one of: +//! +//! - `build_payload` panic / error β€” the builder could not even produce a +//! block from the mempool contents (possible regression in the builder). +//! - Built-BAL-hash vs. header-BAL-hash mismatch (the builder is inconsistent +//! with itself, almost certainly a bug in the BAL finalization step). +//! - Validator rejection (`add_block_pipeline_bal` returns Err) β€” the parity +//! is broken. The error message identifies which check fired. +//! +//! When a test in this module breaks, treat it as a P0 before merging: a green +//! ef-tests blockchain suite does not catch builder/validator drift because +//! ef-tests only consume blocks, never produce them. +//! +//! # Scenario coverage +//! +//! The module has two groups of tests. +//! +//! **Positive parity** β€” builder produces a legitimate block, validator must +//! accept. Guards against silent drift (e.g., someone changes a recording +//! site in the builder but not the check in the validator, or changes the +//! intrinsic gas formula in one path but not the other): +//! +//! - `parity_empty_block` β€” pre-exec system calls; SYSTEM_ADDRESS filter. +//! - `parity_simple_transfer` β€” smoke; balance changes, coinbase handling. +//! - `parity_create_tx` β€” Amsterdam CREATE intrinsic split (EIP-8037 PR #2687). +//! - `parity_sstore_zero_to_nonzero` β€” state gas for fresh storage (EIP-8037). +//! - `parity_balance_of_unused_account` β€” pure-access BAL entry (EIP-7928). +//! - `parity_large_calldata_floor` β€” EIP-7976 calldata floor (16 gas/byte). +//! - `parity_access_list_floor` β€” EIP-7981 access-list data fold-in. +//! - `parity_user_tx_touches_system_address` β€” SYSTEM_ADDRESS in BAL when +//! legitimately touched by user code via `EXTCODEHASH`. +//! - `parity_multiple_txs_different_senders` β€” BAL aggregation across txs, +//! net-zero filter flush on tx boundary. +//! +//! **Negative parity** β€” builder produces a legitimate block, we CORRUPT the +//! BAL (remove an entry / append a surplus entry) and re-hash the header, +//! then hand it to the validator. The validator must reject. Each scenario +//! mirrors one of the Hive `test_bal_invalid_*` cases we fixed in session 3; +//! if any of these flips to "accept", the corresponding BAL validation check +//! has regressed: +//! +//! - `parity_reject_missing_pure_access_account` β†’ Hive +//! `test_bal_invalid_missing_account[access_only]`. Validator must reject +//! when a user-tx `BALANCE`-probed address is missing from the BAL. +//! - `parity_reject_surplus_system_address` β†’ Hive +//! `test_bal_invalid_surplus_system_address_from_system_call`.

Tests (10 new): - `test_cpsb_clamp_to_one_for_tiny_gas_limit`, `test_cpsb_30m_bin_boundary` β€” cpsb quantization boundaries.

Run across Prague / Osaka / Amsterdam at 30M and 120M block gas limits. - `test_call_to_empty_account_with_value_retains_parent_state_gas` β€” EIP-8037 CALL-to-empty-with-value charges new-account state gas in the caller's frame, retained across successful parent continuation. Pairs with the existing `test_child_charge_then_revert_returns_state_gas_to_parent` for the revert direction.

All 7 verified real and fixed in-PR per user request. Critical (L2 consensus/liveness): - `crates/l2/sequencer/block_producer/payload_builder.rs` now enforces the EIP-8037 PR #2703 per-tx 2D inclusion check against the L2's `configured_block_gas_limit` before executing each tx, matching the L1 builder. Without this, the L2 builder could reject valid txs or accept txs that violate one dimension of the block cap. - `fill_transactions` now snapshots and restores `block_regular_gas_used` / `block_state_gas_used` around `apply_plain_transaction` on the `undo_last_tx` rollback path (invalid L2 out-message). Previously those two counters stayed inflated after a rejected tx, polluting `gas_used()` and the final header `gas_used`. High (mempool DoS avenue): - `crates/blockchain/mempool.rs::transaction_intrinsic_gas` now enforces `max(intrinsic_regular + intrinsic_state, floor)` for Amsterdam+, matching the VM's `validate_min_gas_limit` check. Previously a tx with mostly zero calldata could pass mempool admission at the weighted EIP-2028 cost (400 gas for 100 zero bytes) but fail the VM's 6400-gas unweighted floor at block inclusion, polluting the pool. New standalone helper `intrinsic_gas_floor(tx, fork)` added in `crates/vm/levm/src/utils.rs` mirroring `VM::get_min_gas_used` so the mempool / payload builder can compute the floor without a VM instance. Re-exported from `ethrex-vm`. Medium: - `crates/vm/backends/levm/mod.rs` withdrawal index computation switched from `.map(|n| n + 1)` to `.map(|n| n.saturating_add(1))`. The prior form wraps to 0 in release builds when `n == u32::MAX` (the `debug_assert` only fires in debug). - `crates/vm/levm/src/opcode_handlers/system.rs` adds `debug_assert!` at the two reservoir-revert sites verifying `outstanding_delta >= credit_against_drain_delta`. If that invariant is ever violated, the `saturating_sub` silently mischarges the block's regular dimension; a loud debug panic is preferable. Style: - `crates/vm/levm/src/gas_cost.rs::access_list_bytes` β€” replace `keys.len() as u64` with `u64::try_from(...).unwrap_or(u64::MAX)` for consistency with the rest of the codebase. - `crates/vm/levm/src/hooks/default_hook.rs::refund_sender` β€” rename the currently-unused `gas_used_pre_refund` parameter to `_gas_used_pre_refund` at the signature and drop the interior `let _ =` that was silencing it. Expanded doc explains it's kept in the signature for future reintroduction. All 478 tests pass; no behavior changes except the three intentional ones (mempool floor, L2 2D check, L2 counter rollback) plus the already-exercised saturation edge. --- crates/blockchain/mempool.rs | 18 ++++++-- .../block_producer/payload_builder.rs | 46 ++++++++++++++++++- crates/vm/backends/levm/mod.rs | 6 ++- crates/vm/levm/src/gas_cost.rs | 3 +- crates/vm/levm/src/hooks/default_hook.rs | 16 ++++--- crates/vm/levm/src/opcode_handlers/system.rs | 24 ++++++++++ crates/vm/levm/src/utils.rs | 43 +++++++++++++++++ crates/vm/lib.rs | 3 ++ 8 files changed, 144 insertions(+), 15 deletions(-) diff --git a/crates/blockchain/mempool.rs b/crates/blockchain/mempool.rs index 3b7071824f1..94f7c1e21a3 100644 --- a/crates/blockchain/mempool.rs +++ b/crates/blockchain/mempool.rs @@ -21,7 +21,7 @@ use ethrex_common::{ }, }; use ethrex_storage::error::StoreError; -use ethrex_vm::intrinsic_gas_dimensions; +use ethrex_vm::{intrinsic_gas_dimensions, intrinsic_gas_floor}; use tracing::warn; #[derive(Debug, Default)] @@ -517,14 +517,24 @@ pub fn transaction_intrinsic_gas( // `REGULAR_GAS_CREATE = 9000` + `STATE_BYTES_PER_NEW_ACCOUNT * cpsb` for CREATE // instead of the legacy `TX_CREATE_GAS_COST = 53000`.

Spec changes implemented: 1. The no-reorg skip optimization in engine_forkchoiceUpdated is now restricted to the case where the head references a VALID canonical ancestor of the latest known finalized block. Previously ethrex skipped for any canonical ancestor below the current head; that is no longer permitted by the spec for unfinalized ancestors, which must trigger a reorg back. 2. A new -38006 "Too deep reorg" engine error is introduced. It is returned when an FCU would replace more canonical blocks than the client's implementation-specific limit. Mapped through a new InvalidForkChoice::TooDeepReorg variant and a new RpcErr::TooDeepReorg variant carrying JSON-RPC error code -38006. Implementation decisions not specified by the spec: - REORG_DEPTH_LIMIT = 32. The spec leaves this implementation-specific. 32 was chosen because it matches one Ethereum finalization epoch and aligns with the value nethermind picked for the closely related execution-apis PR 770 in their engine-api-glamsterdam branch. - Reorg depth is computed as (latest_block_number - canonical_link_height), where canonical_link_height is the head itself when the head is canonical (canonical-truncate FCU) and the height of head's deepest canonical ancestor otherwise (sidechain reorg). This correctly counts the number of canonical blocks that would be replaced. - The skip optimization fires for head.number <= stored_finalized rather than strict <. Strictly the spec says "ancestor", but treating the finalized block itself as a valid skip target is a no-op in practice. - The change is unconditional and not gated on a fork timestamp. Spec PR 786 edits paris.md, framing the change as a clarification of merge-era semantics rather than a new fork rule, so it applies on all forks. - L2 callers of apply_fork_choice (l2_connection, block_producer, block_fetcher) are intentionally untouched. Their head=safe=finalized pattern always leaves stored_finalized >= head.number, so the new skip rule never fires there, and reorg depth is at most 1. Tests: - The existing test_new_head_with_canonical_ancestor_should_skip smoke test asserted the old behavior. Renamed to new_head_ancestor_of_finalized_should_skip and rewritten to set up an ancestor-of-finalized scenario, which is now the only case that triggers the skip. - All 5 fork-choice smoke tests in test/tests/blockchain pass. - EF blockchain (LEVM + stateless) and state suites pass on the parent branch (verification of the bal-devnet-4 baseline). - Hive engine simulator verification is the next step and should be run before connecting to the devnet.

REVERT opcode keeps the pre-PR-2689 behaviour (spill back to reservoir for the sender refund). Adds: - VM.regular_gas_reclassified accumulator wired into refund_sender's regular-gas formula. - VM.state_gas_reservoir_at_top_message_entry snapshot taken at start of execute() after prepare_execution, so EIP-7702 auth refunds (which refill the reservoir before the top-level message starts) are part of the entry value used by the halt rule. - ContextResult.is_revert_opcode() to distinguish intentional REVERT from ExceptionalHalt at the top level. - Top-level finalize_execution: on ExceptionalHalt, reclassify state_gas_spill_outstanding plus any reservoir surplus over entry, then reset reservoir to entry. On REVERT, refill reservoir with the execution portion (no reclassification). - handle_return_call/_create: on child ExceptionalHalt, reclassify the local frame's outstanding-spill delta and roll back spill_outstanding + reservoir to entry; on child REVERT, keep the prior behaviour.

Apply the per-frame halt formula symmetrically at the top message (with snapshots = 0). For CREATE TX (intrinsic_state > 0), the wipe leaves state_dim at intrinsic_state, so the entire gross spill that was permanently consumed from gas_remaining must surface in regular dim. The credit_against_drain subtraction excludes credits applied to drain (state-dim) from being reclassified to regular-dim, and the regular_gas_reclassified dedup avoids double-counting when sub-frame halts already moved parts of the spill into regular dim. Non-CREATE TX top-halt (intrinsic_state == 0) keeps the existing max(spill_outstanding, reservoir_surplus) rule, since switching to gross-spill there regresses tests where the gross spill represents legitimate state-gas usage that should stay in state dim.

Refunding that second charge generates `applied_to_drain` (no outstanding spill in the frame to credit against) which accumulates into `state_gas_credit_against_drain`. At top-level halt the existing formula ``` state_gas_spill - credit_against_drain - regular_gas_reclassified ``` evaluates to 0 because the **phantom** drain credit cancels the **real** spill from the first inner CREATE that was permanently consumed from `gas_remaining`. This loses the gross spill from the regular dimension and reports `block.gas_used = gas_limit - NEW_ACCOUNT`, diverging from EELS / geth / besu by exactly one `NEW_ACCOUNT` charge per phantom-drain-cancelled spill. ## Fix Cap `credit_against_drain` by `regular_gas_reclassified` at top-halt so only the portion of drain credit **backed by an actual deeper-frame reclassification** (the case PR #2689 / #6558 were tuned for) is excluded from the regular dimension. Phantom drain β€” credits against charges that never spilled β€” flows through and the gross spill correctly surfaces in the regular dimension as required by EELS `total_state - reservoir`. ## Repro Reproduced on bal-devnet-6 with spamoor evm-fuzz traffic β€” first divergent block 21 between ethrex and geth/besu. After this fix all four nodes (geth Γ— 2, besu, ethrex Γ— 2) stay in agreement past the previous fork point. ## Test plan - [x] All 29 existing EIP-8037 unit tests still pass (including upstream's new `test_top_halt_after_partial_credit_to_spill_diverges_from_eels` from #6558) - [x] New focused regression `test_top_halt_phantom_drain_does_not_cancel_real_spill` - [x] Manual verification on Kurtosis devnet-6: 4 clients agree at block 39+, no `match=false` validations across 25+ blocks --- crates/vm/levm/src/vm.rs | 19 +++- .../levm/eip8037_top_level_failure_tests.rs | 90 +++++++++++++++++++ 2 files changed, 108 insertions(+), 1 deletion(-) diff --git a/crates/vm/levm/src/vm.rs b/crates/vm/levm/src/vm.rs index f629ed4b9f4..7b51ba8c1e5 100644 --- a/crates/vm/levm/src/vm.rs +++ b/crates/vm/levm/src/vm.rs @@ -1024,10 +1024,27 @@ impl<'a> VM<'a> { // formula diverged from EELS by `min(applied_to_spill, S - applied_to_spill)` // whenever a credit only partially cancelled outstanding spill β€” see // `test_top_halt_after_partial_credit_to_spill_diverges_from_eels`. + // + // `credit_against_drain` is capped by `regular_gas_reclassified` to + // distinguish "real drain" (a credit against a deeper-frame spill that + // has already been reclassified to regular dim) from "phantom drain" + // (a credit against a charge that itself didn't spill β€” e.g., a charge + // funded entirely from a reservoir refilled by an earlier spill-refund). + // Real drain SHOULD be excluded from regular reclassification (it's + // already counted in `regular_gas_reclassified` from the deeper halt). + // Phantom drain MUST NOT be excluded β€” doing so would lose the original + // gross spill from regular dim.

EELS spec at the bal-devnet-6@v1.1.0 fixture-gen commit (ethereum/execution-specs PR #2711) is explicit: "intrinsic_state_gas is immutable after validation". The refund only flows to message.state_gas_reservoir; block accounting computes tx_state_gas = intrinsic_state_gas + state_gas_used WITHOUT subtracting the refund. Concretely fixes the 72 pointer_to_precompile parametrizations and the state_gas_set_code family in bal-devnet-6@v1.1.0, which expect block.gasUsed to include the full intrinsic_state_gas in the state dimension (max(regular, state) per EIP-7778). NOTE: future spec direction. The bal-devnet-6 spec acknowledges this as a bug locked in for devnet verification only. See ethereum/execution-specs commit 9b3961a65 (added a regression test `test_snobal_block_gas_used_inflated_by_7702_auth_refund`) and its docstring: the intended long-term fix is to add MessageCallOutput.state_refund and subtract it from tx_state_gas, mirroring the SELFDESTRUCT refund pattern. ec5141c93 was implementing that future behavior; we are reverting it because bal-devnet-6 fixtures (current target) require the un-subtracted value. Re-apply the subtraction when bal-devnet-7 fixtures land with the spec fix. --- crates/vm/levm/src/utils.rs | 18 ++++++------------ 1 file changed, 6 insertions(+), 12 deletions(-) diff --git a/crates/vm/levm/src/utils.rs b/crates/vm/levm/src/utils.rs index f77770225e8..169c407a5ae 100644 --- a/crates/vm/levm/src/utils.rs +++ b/crates/vm/levm/src/utils.rs @@ -344,21 +344,15 @@ impl<'a> VM<'a> { // An account can exist in the trie but be empty (e.g., has non-empty storage root). if authority_exists { if self.env.config.fork >= Fork::Amsterdam { - // EELS set_delegation: refund STATE_BYTES_PER_NEW_ACCOUNT * cpsb for each - // existing authority.

Manifested on bal-devnet-6 FullSync as `gas_used` mismatch on block 597 (Ξ” = 131,488 = 1Β·STATE_NEW) for txs with nested CREATEs that all halt. Drain credits already affect `state_gas_refund_absorbed` (reduces net state-gas at finalize) and refill `state_gas_reservoir` via `credit_state_gas_refund`, so they have no further role at top-halt reclassification. The simpler rule is: every byte of gross spill not already reclassified at a deeper halt boundary moves into the regular dimension here. `test_top_halt_phantom_drain_does_not_cancel_real_spill` still passes (the cap was already pinning drain_cap to 0 in that case via the `min(_, regular_gas_reclassified)` clamp).

Each test seeds an Amsterdam-at-genesis chain, puts one or more txs into the -//! mempool, drives the payload builder to produce a block, and then hands the -//! result (block + BAL) back to the validator pipeline via -//! `add_block_pipeline_bal`. A failure therefore surfaces as one of: -//! -//! - `build_payload` panic / error β€” the builder could not even produce a -//! block from the mempool contents (possible regression in the builder). -//! - Built-BAL-hash vs. header-BAL-hash mismatch (the builder is inconsistent -//! with itself, almost certainly a bug in the BAL finalization step). -//! - Validator rejection (`add_block_pipeline_bal` returns Err) β€” the parity -//! is broken. The error message identifies which check fired. -//! -//! When a test in this module breaks, treat it as a P0 before merging: a green -//! ef-tests blockchain suite does not catch builder/validator drift because -//! ef-tests only consume blocks, never produce them. -//! -//! # Scenario coverage -//! -//!

Guards against silent drift (e.g., someone changes a recording -//! site in the builder but not the check in the validator, or changes the -//! intrinsic gas formula in one path but not the other): -//! -//! - `parity_empty_block` β€” pre-exec system calls; SYSTEM_ADDRESS filter. -//! - `parity_simple_transfer` β€” smoke; balance changes, coinbase handling. -//! - `parity_create_tx` β€” Amsterdam CREATE intrinsic split (EIP-8037 PR #2687). -//! - `parity_sstore_zero_to_nonzero` β€” state gas for fresh storage (EIP-8037). -//! - `parity_balance_of_unused_account` β€” pure-access BAL entry (EIP-7928). -//! - `parity_large_calldata_floor` β€” EIP-7976 calldata floor (16 gas/byte). -//! - `parity_access_list_floor` β€” EIP-7981 access-list data fold-in. -//! - `parity_user_tx_touches_system_address` β€” SYSTEM_ADDRESS in BAL when -//! legitimately touched by user code via `EXTCODEHASH`. -//! - `parity_multiple_txs_different_senders` β€” BAL aggregation across txs, -//! net-zero filter flush on tx boundary. -//! -//! **Negative parity** β€” builder produces a legitimate block, we CORRUPT the -//! BAL (remove an entry / append a surplus entry) and re-hash the header, -//! then hand it to the validator. The validator must reject. Each scenario -//! mirrors one of the Hive `test_bal_invalid_*` cases we fixed in session 3; -//! if any of these flips to "accept", the corresponding BAL validation check -//! has regressed: -//! -//! - `parity_reject_missing_pure_access_account` β†’ Hive -//! `test_bal_invalid_missing_account[access_only]`. Validator must reject -//! when a user-tx `BALANCE`-probed address is missing from the BAL. -//! - `parity_reject_surplus_system_address` β†’ Hive -//! `test_bal_invalid_surplus_system_address_from_system_call`. Validator -//! must reject when the BAL contains `SYSTEM_ADDRESS` without any user tx -//! touching it (system-call-only). -//! - `parity_reject_missing_storage_read` β†’ Hive -//! `test_bal_invalid_field_entries[missing_storage_read]`. Validator must -//! reject when a `SLOAD`-ed slot is missing from `storage_reads`. -//! - `parity_reject_missing_storage_change` β†’ Hive -//! `test_bal_invalid_field_entries[missing_storage_change]`. Validator must -//! reject when an `SSTORE`-written slot is missing from `storage_changes`. -//! - `parity_reject_missing_code_change` β†’ Hive -//! `test_bal_invalid_field_entries[missing_code_change]`. Validator must -//! reject when a `CREATE`d contract's `code_changes` entry is missing -//! (guards the PR-#6463-adjacent PART B pre-state fallback added in -//! session 3). -//! -//! Future additions should continue to target specific spec mechanisms rather -//! than broad coverage: every scenario we add costs CI time, so each test -//! should guard against at least one concrete spec rule or one known drift -//! risk.

It wasn't β€” 25 of the 28 tests had been on `main` for a while (landed in PR #6322, well before this branch diverged). Only 3 tests were genuinely added on this PR: - test_burn_logs_emitted_in_lex_ascending_order_three_accounts - test_coinbase_priority_fee_does_not_emit_transfer_log - test_multi_selfdestruct_dest_emits_single_burn_log_with_combined_balance Those three are covered by the EELS burn/transfer-logs ef-tests we now run via the blockchain runner, so dropping them is correct. The other 25 belong to main and should not have been touched here. Restored to main verbatim and added the new `Environment::is_system_call` field introduced by this PR. --- test/tests/levm/eip7708_tests.rs | 1232 +++++++++++++++++++++++++++++- 1 file changed, 1225 insertions(+), 7 deletions(-) diff --git a/test/tests/levm/eip7708_tests.rs b/test/tests/levm/eip7708_tests.rs index 9ae1d816a19..22f8bace378 100644 --- a/test/tests/levm/eip7708_tests.rs +++ b/test/tests/levm/eip7708_tests.rs @@ -1,28 +1,780 @@ //!

Per execution-apis PR 786 point 6 the limit for `-38006` is "specific to the client software" β€” Erigon, Nethermind, Besu and geth all scope it to their state-retention/unwind capability, not to a finalized-crossing policy. ethrex's stricter reading caused legitimate CL-driven reorgs to be rejected. CLMock's `DefaultSlotsToFinalized = 2` puts `stored_finalized` two blocks behind head during canonical chain construction. Hive then asks for an 8- or 10-block sidechain reorg; canonical_link sits below finalized, the old check fired with `Reorg depth 8 exceeds the client's limit of 2`, and the test asserted Valid β†’ FAIL. Spec compliance preserved: - Point 2 (skip when head is canonical ancestor of finalized) still handled by the `NewHeadAlreadyCanonical` branch at fork_choice.rs:81. - Point 5 (`-38002 Invalid forkchoice state` for disconnected safe/ finalized) unaffected. - Point 6 (`-38006 Too deep reorg`) still returned when `reorg_depth > REORG_DEPTH_LIMIT (128)` β€” ethrex's actual state-history cap. We now match the industry-wide reading: trust the CL's fork choice and only refuse when we physically cannot unwind. Also drops the 8 hive Block-Re-Org entries from `KNOWN_EXCLUDED_TESTS` in `.github/scripts/check-hive-results.sh` and the matching section in `docs/known_issues.md`.

Docstring: "no mutation of intrinsic_state_gas". Drops the two extra subtractions previously added in `cefdf69de` that anticipated EELS PR #2711 / #2816 (the bal-7 `state_refund` channel). For bal-6 the block-level `state_gas_used` intentionally stays "inflated" by the auth refund β€” the refund is sender-side only in this devnet. Block-accounting subtraction lands in bal-devnet-7 via the separate `state_refund` channel.
