Bastien Nocera d15282bff1 lib: Remove minutiae utils from internal header 
It's only used by drivers.
 2018-05-29 13:34:18 +02:00
Bastien Nocera 00637c4f0b lib: Remove fprint_get_drivers() from drivers API 
Drivers don't need to get a list of drivers.
 2018-05-29 13:34:18 +02:00
Bastien Nocera 2e035a7f45 lib: Make fpi_ssm opaque for drivers 
We shouldn't access fpi_ssm struct fields directly in drivers, so add
accessor and setter functions for the common uses.
 2018-05-29 13:34:18 +02:00
Bastien Nocera 17577175f8 lib: Remove fpi_driver_to_img_driver() from drivers API 
It's only used internally to the library.
 2018-05-29 13:34:18 +02:00
Bastien Nocera 933fab6ed4 lib: Remove array_n_elements() from internal header 
It's unused.
 2018-05-29 13:34:18 +02:00
Bastien Nocera 7e5661caff lib: Don't include assembling.h in internal header 
It's not needed.
 2018-05-29 13:34:18 +02:00
Bastien Nocera 19dfb138a6 drivers: Use new drivers_api.h in drivers 2018-05-29 13:34:18 +02:00
Bastien Nocera 0930f2614c lib: Use public header in helper files 
aeslib.h and assembling.h don't need access to internal data structures,
so make them include the public fprint.h rather than the internal header
fp_internal.h.
 2018-05-29 13:34:18 +02:00
Bastien Nocera 1b20521e5c lib: Add drivers_api.h file 
This will hide library internals, for the purpose of making the drivers
API documentable.
 2018-05-29 13:34:18 +02:00
Bastien Nocera 0e351db91a lib: Fix new BUG_ON() implementation again 
This time, the macro didn't wrap the condition, resulting in calls
like BUG_ON(size > 100) being expanded to g_assert(!size > 100), when
what we wanted was BUG_ON(!(size > 100)).

See 9cca501650,
ff09456cf5, and egg on my face.

Bastien Nocera 9cca501650 lib: Fix new BUG_ON() implementation 
A thinko reversed the meaning of the BUG_ON() condition. This fixes
the inverted implementation in commit
ff09456cf5.

Bastien Nocera bc3959d1e0 lib: Fix internal deprecation warning 
Remove deprecation warning that comes from an internal function, it
serves no purpose, and the function itself is deprecated.

Follow-up from commit 1f0079a274.

Bastien Nocera 994061af44 drivers: Simplify headers 
Remove all the headers already included through "fp_internal.h" such as
<libusb.h> and <errno.h>, include "assembling.h" and "driver_ids.h" there
as well to avoid doing it in (almost) every driver.

Bastien Nocera 501020921e vfs301_proto: Use GLib helpers

Bastien Nocera 1f0079a274 data: Mark all the fp_dscv_print functions as deprecated 
As this is pretty much copy/pasted in fprintd, and should instead be
implemented by whatever system actually stores the data, rather than
in a generic but not quite "fits-all-purpose" way.

Bastien Nocera fc92f62136 build: Remove the need to modify sources for new drivers 
Instead of having to modify both fp_internal.h to list each driver
definition structure, and core.c to add those drivers to arrays we
can loop over, generate both of those using meson.

Bastien Nocera 8e6e23b8d0 build: Always enable debugging logging 
We shouldn't need to specifically enable debug logging to get useful
data out of a compiled libfprint either, so always enable debugging
output. It will still be switched off at runtime, by default.
 2018-05-23 19:11:02 +02:00
Bastien Nocera 63e5d56441 build: Always allow switching log level at runtime 
There are no parts of libfprint that are so resource intensive that we'd
want to disable logging. This avoids (hopefully rare) cases where
compiled versions of libfprint are distributed with logging completely
disabled, and thus can't be debugged.

Vasily Khoruzhick 2944a35e74 imgdev: Add fpi_imgdev_abort_scan() to abort scan gracefully from within the driver. 
Smart sensors like Upek TouchChip Coprocessor can provide scan status instead
of image, as result we need to report such status as "short scan" or "finger not centered"
from within the driver, since it's not a session error.

Timo Teräs 9f408bf51b imgdev: fix enum mismatch for dev_change_state() call 
This bug has existed long time, but it was uncovered by commit
e215b05094 which enabled multiple enrollment rounds.

In practice this broke (at least) URU4000 driver state machine
causing it to enter indefinite loop - due to the invalid state
change callback.

Vasily Khoruzhick 061a457658 aeslib: improve frame-assembling routines 
Some scanners provide hardware assistance in frame assemling, i.e.
horizontal and vertical offset to previous frame is provided. This
commit improves code to utilise that assistance. Sensors without
hardware assistance will use software algorithm, which was also
improved to do search in horizontal direction.

Matthew Garrett a99e813bbf Add udev rules to set devices to autosuspend 
Most fingerprint readers can be suspended safely, so use
the udev rules to autosuspend them when they appear.

The script itself contains whitelists and blacklists.

Bastien Nocera 014b933b2b Add gdk-pixbuf support 
When imaging support is required, we prefer to use gdk-pixbuf,
as it's already on things like Live CDs.
Also fix the examples building against the system libfprint.

Daniel Drake 642010643d uru4000: Add support for Microsoft Fingerprint Reader v2 
After lot 713, Microsoft fingerprint readers changed. The new version
comes with a new USB product ID and a challenge-response authentication
scheme where the device challenges the authenticity of the driver.

An independent third party produced documentation on the computations
needed to convert a challenge into the correct response, and I then used
this documentation to produce a clean-room reimplementation of the
authentication scheme.

Anthony Bretaudeau 8e0e8e4386 aes1610: imaging improvements 
bz threshold is now 10 (instead of 15). I think it is ok for the moment.
If we manage to get higher image quality in the future, we'll change that.

max_frame is set to 350. 150 was too low => incomplete fingerprints

the driver was designed to stop the acquisition as soon as it gets a blank
frame (=> incomplete fingerprints). Now it waits to have at least 50 blank
frames before stopping.

Anthony Bretaudeau c5a550e42c Add Authentec AES1610 driver 
This is an active capacitance swipe-type device similar to but smaller
than the AES2501.

Image processing performance is good but matching performance is not so
good. The bozorth3 matcher needs tweaking in order to better cope with
small sets of minutiae.

With a lowered threshold, matching performance is good enough for now.
