Update Sp1 Patches

Update SP1 Patches for New Version

Update all patched crates from SP1 version $0 to $1.

Context

SP1 maintains patched versions of cryptographic crates in the sp1-patches GitHub organization. These patches:

• Depend on sp1-lib from crates.io
• Are referenced via git tags in Cargo.toml files
• Follow the naming convention: patch-[CRATE]-[VERSION]-sp1-[SP1_VERSION]

When releasing a new SP1 version, patches must be updated so their sp1-lib dependency matches.

Step 1: Identify Current Patches

Find all patch references in the codebase:

grep -r "sp1-patches" --include="*.toml" . | grep -v target | grep "tag ="

Key locations:

• patch-testing/Cargo.toml - Main patch testing workspace
• patch-testing/*/program/Cargo.toml - Individual program tests
• examples/Cargo.toml - Example programs
• crates/test-artifacts/programs/*/Cargo.toml - Test artifacts
• crates/verifier/guest-verify-programs/Cargo.toml - Verifier programs

Step 2: Categorize Repositories

Repos WITH sp1-lib dependency (need version update):

• curve25519-dalek - Ed25519 curve operations
• curve25519-dalek-ng - Ed25519 (ng version)
• tiny-keccak - Keccak hashing
• bn (substrate-bn) - BN254 pairing
• bls12_381 - BLS12-381 pairing
• RustCrypto-RSA - RSA operations
• elliptic-curves (k256, p256) - ECDSA operations

Repos with TRANSITIVE sp1-lib dependency:

• rust-secp256k1 - depends on k256 from elliptic-curves

Repos WITHOUT sp1-lib (create alias tags):

• RustCrypto-hashes - SHA2, SHA3 patches
• RustCrypto-bigint - BigInt operations

Step 3: Update Process

For repos WITH sp1-lib:

cd /tmp/sp1-patches-update
git clone git@github.com:sp1-patches/<REPO>.git
cd <REPO>

# Checkout old tag
git checkout patch-<CRATE_VERSION>-sp1-<OLD_SP1_VERSION>
git checkout -b temp-update-branch

# Find and update sp1-lib version (check format first!)
grep -r "sp1-lib" --include="Cargo.toml" .

# Update (adjust sed pattern based on format found):
# For: sp1-lib = "X.Y.Z"
sed -i 's/sp1-lib = "<OLD_VERSION>"/sp1-lib = "<NEW_VERSION>"/g' */Cargo.toml Cargo.toml

# For: sp1-lib = { version = "X.Y.Z", ... }
sed -i 's/sp1-lib = { version = "<OLD_VERSION>"/sp1-lib = { version = "<NEW_VERSION>"/g' */Cargo.toml Cargo.toml

# Commit and create new tag
git add -A
git commit -m "Update sp1-lib dependency to <NEW_VERSION>"
git tag patch-<CRATE_VERSION>-sp1-<NEW_SP1_VERSION>
git push origin patch-<CRATE_VERSION>-sp1-<NEW_SP1_VERSION>

For repos with TRANSITIVE dependencies (rust-secp256k1):

Also update references to other sp1-patches repos:

# Update k256 dependency tag
sed -i 's/patch-k256-13.4-sp1-<OLD>/patch-k256-13.4-sp1-<NEW>/g' Cargo.toml

For repos WITHOUT sp1-lib (alias tags):

git checkout patch-<CRATE_VERSION>-sp1-<OLD_SP1_VERSION>
git tag patch-<CRATE_VERSION>-sp1-<NEW_SP1_VERSION>
git push origin patch-<CRATE_VERSION>-sp1-<NEW_SP1_VERSION>

Step 4: Update Local Cargo.toml Files

# Find all files with old tags
find . -name "Cargo.toml" -exec grep -l "sp1-<OLD_VERSION>\"" {} \;

# Update all occurrences
find . -name "Cargo.toml" -exec sed -i 's/-sp1-<OLD_VERSION>"/-sp1-<NEW_VERSION>"/g' {} \;

Step 5: Verify

# Check tags exist on GitHub
gh api repos/sp1-patches/<REPO>/git/refs/tags/patch-<VERSION>-sp1-<NEW> --jq '.ref'

# Build to verify resolution
cd patch-testing && cargo check

# Ensure no old tags remain
grep -r "sp1-<OLD_VERSION>\"" --include="*.toml" . | grep -v target

Tag Reference

Important Notes

• Never overwrite existing tags - always create new tags
• Check sp1-lib format before sed replacement (simple string vs table format)
• Update transitive deps first - elliptic-curves before rust-secp256k1
• Verify with cargo check - ensures all dependencies resolve correctly
