Leonardo Francisco 95fccfdac8 validity: Iteration 4 — Sensor identification and HAL tables
Add post-TLS sensor identification infrastructure:

TLS command mechanism (vcsfw_tls_cmd_send):
- Reusable 2-state subsm for sending VCSFW commands inside TLS channel
- Uses 0x44 prefix + TLS app_data wrapping for sends
- Decrypts TLS response and extracts VCSFW status + payload

Sensor identification (cmd 0x75):
- validity_sensor_parse_identify() parses hw_major/hw_version
- DeviceInfo table (26 entries): maps (major, version) to device name
  and sensor type, with exact and fuzzy matching
- SensorTypeInfo table (14 entries): maps sensor_type to geometry
  parameters (bytes_per_line, line_width, calibration blob, etc.)

Factory bits retrieval (cmd 0x6f):
- validity_sensor_build_factory_bits_cmd() builds 9-byte command
- Response stored in sensor state for calibration (Iteration 5)

Open sequence integration:
- 4 new SSM states: OPEN_SENSOR_IDENTIFY, OPEN_SENSOR_IDENTIFY_RECV,
  OPEN_SENSOR_FACTORY_BITS, OPEN_SENSOR_FACTORY_BITS_RECV
- Sensor state init/clear wired into dev_open/dev_close

New files: validity_sensor.h, validity_sensor.c
Tests: 14 unit tests in test-validity-sensor.c (all passing)
Full suite: 6/6 OK, 0 failures

History

LibFPrint was originally developed as part of an academic project at the University Of Manchester.

It aimed to hide the differences between consumer fingerprint scanners and provide a single uniform API to application developers.

Goal

The ultimate goal of the FPrint project is to make fingerprint scanners widely and easily usable under common Linux environments.

License

Section 6 of the license states that for compiled works that use this library, such works must include LibFPrint copyright notices alongside the copyright notices for the other parts of the work.

LibFPrint includes code from NIST's NBIS software distribution.

We include Bozorth3 from the US Export Controlled distribution, which we have determined to be fine being shipped in an open source project.
