Cloud-Probe v0.9.2-rc.1

This is an internal release candidate ahead of v0.9.2. The headline change is a cpctl CLI refactor plus hardening of the cpworker unix control
plane. Not intended for external use — please report issues before the final v0.9.2 cut.

⚠️ Breaking Changes (cpctl)

• Removed worker subcommand layer. ping, info, and stats are now top-level commands.
  • Old: cpctl worker stats ...
  • New: cpctl stats ...
• Renamed --control / -s flag to --unix / -u. It now takes a raw unix socket path (no scheme prefix).

✨ cpctl Improvements

• New top-level commands: ping, info, stats — each with its own focused flag set.
• --timeout is now plumbed through to context deadlines in the unix client, so hung calls actually abort.

🛡️ cpworker Hardening (unix-manager)

• New unix_rpc_basic module split out from unix-manager for the basic RPC handlers.
• Improved error handling and client lifecycle management on the unix control socket.

🧪 Tests & Tooling

• Added Go unit tests for cpctl commands (ping, info, stats, base) and the cpgolib/cpworker unix client.
• Added a C unit test for unix control (cpworker/tests/unit/unix_control.c).
• Added shell unit tests under scripts/tests/.
• New justfile + scripts/routers/ for local / ssh / orb build dispatch.
• New .env.example; CPW_SKIP_ENV_LOCAL escape hatch for environments that shouldn't auto-load .env.local.

Cloud-Probe v0.9.1

Title: add packet_split for vxlan and NicChangeDetect

Highlights

• Added VXLAN packet splitting support in cpworker.
• Added NIC change detection in cpdaemon syncer flow, with automatic re-registration behavior.
• Expanded unit and integration test coverage, including new VXLAN split scenarios.

Added

• New packet split module:
  • cpworker/src/packet_split.c
  • cpworker/src/packet_split.h
• New VXLAN split example config:
  • cpworker/examples/libpcap_vxlan_split.json
• New integration test framework and cases under:
  • cpworker/tests/integration/
• New unit tests for packet splitting:
  • cpworker/tests/unit/packet_split.c

Changed

• output_vxlan now supports split options:
  • split.max_payload_size
  • split.recalculate_checksum
• cpdaemon strategy/model/config pipeline now carries packet split fields:
  • hasPacketSplit
  • packetSplitBytes
  • recalculateChecksum
• Added syncer config support for NIC change detection:
  • syncer.nic_change_detect_enable
  • periodic NIC scan + re-register trigger on change
• Refactored test layout from cpworker/tests/ to clearer cpworker/tests/unit and cpworker/tests/integration.

Fixed / Improved

• VXLAN output error handling improvements (including better error formatting and socket cleanup in error paths).
• Packet parsing/splitting path includes IPv4/IPv6 + TCP/UDP handling and optional checksum recalculation support.
• Added deeper debug visibility for synced strategy payloads in cpdaemon.

Validation

• Added/updated test assets for:
  • file output
  • GRE output
  • VXLAN basic + VXLAN split (TCP/UDP)
  • ZMQ output
