      Print discovery · 447b1f01
      Daniel Drake authored
      Add concept of "discovered prints" and flesh out the API. A discovered print
      was found based on file name but has not been checked for file integrity,
      and of course there is no guarantee that it is usable when you try to
      use it later (might have been deleted, etc).
      The .fprint directory structure was changed - instead of using mnemonics
      like "rind" we use their numeric value in the fp_finger enum as the filename.

      Improve print_data structure and on-disk format · 294f9ad4
      Daniel Drake authored
      Drivers now have an ID number. These will be assigned by me and documented
      on the wiki. 0 cannot be used.
      Drivers now define a devtype for each device they initialise. This is to
      cope with the situation where a driver can support varying devices where
      their print data is incompatible (i.e. image scaling is totally changed).
      This doesn't apply to any existing supported devices.
      Print data no longer includes driver name, and includes driver ID instead.
      Paths to saved print data now include driver ID and devtype, and no longer
      include driver name.
      APIs exposed for converting a print_data into a blob which can then
      be loaded back again later. Useful for systems who don't want to use
      my simple storage system (which is only aimed at a single user).
      File format is now defined and will be documented on the wiki. The header
      is larger as we can no longer rely on directory paths in all scenarios.
      Print data compat check now checks devtype and driver ID.

      Basic image driver foundations · 2709c6dc
      Daniel Drake authored
      The basic model is that image drivers declare a fp_img_driver structure
      rather than a fp_driver struct. fp_img_driver will contain primitive imaging
      operations such as 'scan finger and return image'. The imgdev layer will
      generically implement the primitive fp_driver operations, and the imgdev
      layer will fix up the enroll/verify/etc pointers at driver registration
      Removed const from all fp_driver declarations, as these are now modified
      dynamically in the case of imaging drivers.

      Enrollment: improved error reporting · 39271b4f
      Daniel Drake authored
      Convert enrollment function to return a signed integer, which is negative
      on error or corresponds into fp_enroll_result otherwise.
      Now we can treat a 'FAIL' condition differently from an actual error: fail
      means that enrollment didn't complete because the data was nonsense or
      whatever (e.g. scanned a different finger for each stage?).
      Updated upekts accordingly.

      upekts: communication handling and enrollment implementation · ab5b1ca8
      Daniel Drake authored
      This completes an enrollment implementation for the upekts driver.
      It's based on code from libthinkfinger, but as there seemed to be many
      unknown details there, I spent some time analysing the bus messages in
      more detail and have effectively rewritten almost all of the borrowed code.
      Note that libthinkfinger is GPL licensed, so that reflects on this code too.
      At release time I will ask them if they are OK for me to relicense it.

      Enrollment tweaks · 50e2de07
      Daniel Drake authored
      upekts will need to know when the first enrollment stage is attempted for
      the first time, so add an __enroll_stage counter which actually indicates
      the next stage to enroll. -1 is a special value and it means 0 is next *and*
      it is the initial attemt.
      Added more debug output to the enroll handler.
      Added new fp_enroll_status codes for too short or uncentered scans.
      Changed the print_data allocator to consider the device rather than the
      driver, this feels more natural. Added missing return value.
      Make fp_enroll_status codes start at 1. 0 can now be used as a
      special/temporary value by the drivers. Also check that we aren't exceeding
      the number of enroll stages.
      Also add a missing exit() call to the verify example and update for the
