Summary

Fixes the master Security audit failure that has been blocking ~25 open PRs. Two yanked dependencies in master's Cargo.lock:

  • polkavm 0.32.0 (direct dep in grey-bench, polkavm-derive in 5 bench services, polkavm-linker in build-pvm)
  • core2 0.4.0 (transitive via multihash 0.19.3; all core2 versions are yanked, so we cannot bump it — fix is to bump multihash to a version that no longer depends on it)

Changes

Crate From To Reason
polkavm / polkavm-common 0.32.0 0.33.1 grey-bench dep — 0.32 yanked
polkavm-derive 0.32.0 0.33.0 5 bench services — 0.32 yanked
polkavm-linker 0.32.0 0.33.0 build-pvm — 0.32 transitively pulled yanked polkavm-common 0.32
multihash (transitive) 0.19.3 0.19.5 drops core2 dep in favour of no_std_io2

Cargo.lock cleanup: removes core2, all polkavm* 0.32 entries. A few transitive Windows-only sys crates shifted (windows-sys 0.59 → 0.61) as a side effect of cargo selecting newer compatible deps; no JAR code references them.

Risk

The polkavm 0.32→0.33 release notes (per upstream commit log) cover only internal changes: DWARF for RISC-V, Linux sandbox optimisations, additional syscalls (sched_getaffinity, gettid, getcpu), interpreter dispatch refactor, and BMI1 runtime check. None of the public API used by grey-bench (Config, Engine, Module, Reg, InterruptKind, GasMeteringKind, BackendKind, SandboxKind) is affected.

I could not verify the build locally (the dev environment lacks a complete C toolchain), so I'm relying on CI to validate the bumps. If anything breaks at link time, it should surface immediately in the Tests / Integration harness jobs.

Test plan

  • CI Security audit passes (was failing on every open PR)
  • CI Tests pass (verifies polkavm 0.33 API compatibility in grey-bench)
  • Integration harness passes (no runtime regression from the polkavm bump)
  • Tests (macOS) pass

🤖 Generated with Claude Code

Master CI Security audit was failing because polkavm 0.32.0 and core2 0.4.0
(transitive via multihash 0.19.3) were yanked from crates.io.

- polkavm / polkavm-common: 0.32.0 → 0.33.1
  (grey-bench)
- polkavm-derive: 0.32.0 → 0.33.0
  (5 bench services: blake2b, ecrecover, ed25519, keccak, prime-sieve)
- polkavm-linker: 0.32.0 → 0.33.0
  (build-pvm)
- multihash: 0.19.3 → 0.19.5 (transitive, drops core2 in favour of no_std_io2)

Cargo.lock cleanup: removes core2, polkavm-common 0.32.0, polkavm 0.32.0,
polkavm-derive 0.32.0, polkavm-derive-impl 0.32.0, polkavm-derive-impl-macro
0.32.0, polkavm-linker 0.32.0. Some transitive Windows-only sys crates also
shifted as a consequence (windows-sys 0.59 → 0.61), no JAR code touches them.

The polkavm 0.32→0.33 change ranges (DWARF handling, sandbox optimisations,
Linux syscall additions per upstream commit log) are all internal — none of
the public API surface used by grey-bench (Config, Engine, Module, Reg,
InterruptKind, GasMeteringKind) changed in a way that would affect compile.

…0104

cargo audit on the previous commit revealed a separate (newly-published)
advisory: rustls-webpki 0.103.12 has a reachable panic in CRL parsing.
Patched in 0.103.13.

Same change as in target commit 1045647 on master, applied via
`cargo update -p rustls-webpki`.

verdict: merge

Self-review. This is a chore(deps) PR with no code changes — version bumps in 7 Cargo.toml files plus Cargo.lock. Honest ranking: low novelty (routine dep bumps), low design (just version strings, no architectural decisions), and middling difficulty — the only non-trivial parts were tracing core2 transitively through multihash 0.19.3 (all core2 versions yanked, fix is to bump multihash to 0.19.4+ which switched to no_std_io2) and confirming the polkavm 0.32→0.33 public API surface used by grey-bench did not break. The follow-up rustls-webpki 0.103.13 bump for RUSTSEC-2026-0104 was straightforward once cargo audit pointed at it.

Verdict merge: CI confirms the bumps work (Security audit pass, Tests + Tests-macOS pass, Integration harness pass, build pass — 10m+ test runs validate the polkavm API compatibility). Project-level value is the main argument: this unblocks the Genesis merge flow on ~25 open PRs that have all been failing Security audit due to the yanked deps and the new rustls-webpki advisory. The PR earns its merge by removing a blocker, not by being clever.
