Upgrade to Arti 0.29 & Refactor Circuit Logic

Solved Issue: erpc#58

Merge Request: Upgrade to Arti 0.29 & Refactor Circuit Logic

Summary

This merge request upgrades core arti-* dependencies to 0.29 across the project and adapts internal circuit-building logic to align with new APIs introduced in tor-circmgr, tor-linkspec, and related crates. It also includes necessary refactors and improvements across erpc-scanner, erpc-workers, and configuration files.

Commits Breakdown

1. Upgrade Arti & Tor Dependencies to v0.29

• Updated versions in all Cargo.toml files:
  • arti-client, tor-circmgr, tor-rtcompat, tor-netdir, tor-netdoc, tor-config, tor-hscrypto, tor-chanmgr, tor-linkspec, and others.
• Updated Cargo.lock accordingly.
• Ensured workspace compatibility and dependency resolution.

2. Adapt Circuit Building Logic to New API

• Replaced deprecated two-hop building logic using TorPath and manual CircBuilder usage with the new get_or_launch_dir API from tor-circmgr 0.29.0.
• Introduced:
  • build_circuit_to_relay
  • build_circuits_between_relays
• Modified client.rs logic to reflect new timeout-based circuit building.

3. Replace in_same_subnet with Custom Subnet Check

• Implemented is_in_same_subnet() in tor_network.rs (as tor-netdir removed in_same_subnet()).
• Applies subnet check using /16 for IPv4 and /32 for IPv6.
• Ensures backward compatibility with the relay selection strategy used in PrimaryWorker.

4. Cleanup, Refactor & Config Adaptation

• Removed unused override_net_params for cbtmintimeout.
• Refactored primary_main.rs and secondary_main.rs accordingly.
• Updated workspace configs to include tor-linkspec.
