Cross-Function Reentrancy +An attacker contract attempts to call a *different* guarded function during a callback: +- `withdraw_bond` → `on_withdraw` callback → `slash_bond` (cross-function re-entry) + +**Result**: Blocked by Soroban runtime.

Zero-address sentinel (`GAAAA...`) and own address rejected via `require_valid_admin_address`. 4. Role assignment requires caller ≥ target role; no self-assignment of equal/higher role. 5. `remove_admin` requires caller strictly outranks target; `MinAdmins` guard prevents last-SuperAdmin removal. 6. `suspend_admin`: `until_ts` must be strictly future; effective-active count must stay ≥ `MinAdmins`; cannot suspend permanently deactivated admins; auto-reactivation at `until_ts`. 7. Ownership transfer enforces `OWNERSHIP_TRANSFER_TIMELOCK = 86_400` seconds before `accept_ownership`. | +| **Ledger/Time** | `e.ledger().timestamp()` for `assigned_at`, `suspended_until` comparison, and ownership timelock expiry. `e.ledger().sequence()` emitted in `admin_rotated` event.

On-chain drift detection via `assert_self_consistent` after every state-changing write, panicking with `InvariantViolation` (code 218). **I1**: attestation weight sum ≥ 0. **I2**: slashed ≤ bonded. **I3**: withdrawal request ⇒ rolling bond. **I4**: bonded ≥ 0. **I5**: slashed ≥ 0. **I6**: notice period ≤ bond duration. **I7**: attestation count matches list length. Additional: same-ledger liquidation guard prevents sandwich attacks; reentrancy guard (application-level + Soroban runtime); CEI pattern for all external-call-bearing functions. | +| **Ledger/Time** | Extensive: `e.ledger().timestamp()` for bond start/expiry, early-exit, cooldown, grace windows, notice periods, attestation deadlines. `same_ledger_liquidation_guard` records ledger sequence after collateral-increasing actions.

A **separate** entrypoint, `CredenceBond::slash_bond(admin, +identity, slash_amount, idempotency_salt)`, exists on the contract for +callers that need idempotency-salt replay protection and a reentrancy lock +around an optional `on_slash` callback. Prior to this addendum, that +entrypoint: + +- Accepted any `i128` `slash_amount`, including negative and zero values, + which could decrease `slashed_amount` or underflow the over-slash check. +- Used unchecked `+` to compute the new cumulative slashed amount. +- Never emitted a `bond_slashed` event, so indexers and the reputation engine + could not observe slashes performed through this path. +- Did not compile at all (it referenced an `identity` binding that was not a + parameter of the function — a leftover from an earlier merge). + +This has been fixed to match the `slash()`/`slashing::slash_bond()` contract: + +- `slash_amount > 0` is required, checked before the reentrancy lock is + acquired (so an invalid call never has a lock to leak). +- The cumulative slashed amount is computed with `checked_add`, and the + existing `new_slashed > bonded_amount` cap is preserved. +- `bond_slashed` is emitted via `slashing::emit_slashing_event`, the same + emitter used by `slash()`, keeping the two entrypoints' event payloads + identical: `(identity, slash_amount, total_slashed_amount)`. +- The reentrancy lock is released on every panic path within the function + (admin check happens before the lock is acquired at all; every panic after + that point calls `release_lock` first). +- A duplicate, unconditional `admin.require_auth()` call was removed — the + entrypoint already goes through `guards::require_admin`, which performs the + auth check itself. Calling `require_auth()` twice on the same address + within one invocation caused the Soroban test host to reject the call with + `Error(Auth, ExistingValue)` ("frame is already authorized"), which is what + surfaced this while writing the new tests below. + +Coverage: [`contracts/credence_bond/tests/slash_bond_validation.rs`](contracts/credence_bond/tests/slash_bond_validation.rs) +(9 tests — negative/zero rejection, event payload and cumulative totals, +exact-cap and over-cap behavior, reentrancy-lock release after a rejected +call, non-admin rejection). Run in isolation with +`cargo test -p credence_bond --test slash_bond_validation`. + +Getting this entrypoint to compile also required fixing several unrelated +pre-existing issues blocking the whole crate: duplicate/missing variants in +`credence_errors::ContractError` (`TimestampInFuture`, `InvalidCurrency`, +`BytesTooLarge`/`InvariantViolation`, `SignatureExpired`, +`DuplicateIdempotencyKey`), a `guards::load_bond` signature that didn't match +its callers, and several other functions (`get_identity_state`, `get_tier`, +`get_bond_status_snapshot`, `migration::migrate_v1_to_v2`, +`invariants::assert_self_consistent`, `slashing::slash_bond`/`unslash_bond`) +that referenced an `identity` binding without declaring it as a parameter. +See the PR for the full list. The wider pre-existing `#[cfg(test)]` test +suite (~100 unrelated compile errors spanning stale API calls, a missing +`credence_math::Timestamp` constant, and test fixtures for methods that no +longer exist) was **not** touched — that is a separate, unrelated cleanup +effort tracked outside this issue. diff --git a/TEST_EXECUTION_GUIDE.md b/TEST_EXECUTION_GUIDE.md new file mode 100644 index 000000000..803a23302 --- /dev/null +++ b/TEST_EXECUTION_GUIDE.md @@ -0,0 +1,334 @@ +# Test Execution Guide for Issue #1311 + +## Quick Reference + +**Issue**: Add boundary and recovery test coverage for contracts/arbitration/src/status.rs +**Tests Added**: 91 comprehensive test functions +**Status**: ✅ Complete and ready for review + +--- + +## Prerequisites + +Ensure you have Rust 1.89.0+ installed (as specified in `rust-toolchain.toml`): + +```bash +rustc --version #
