The driver might forget to set the type of the print. Catch that error a
bit earlier rather than failing when the API user tries to load it from
disk again.
The type of the print (RAW or NBIS) needs to be filled in by the driver.
For most drivers the image devices does this (NBIS), but the
corresponding call was missing in the upekts driver, rendering the
enrolled print unusable.
__handle_incoming_msg would copy the payload of the message into a newly
created buffer just to destroy it again immediately after calling the
callback. Just reference the correct address inside the original package
instead.
Also, in one case the extra buffer was leaked afterwards.
The driver would correctly calculate the amount of extra space needed to
receive the whole packet. It would also request the correct number of
bytes for this transfer.
However, the reallocated buffer to hold this data was directly derived
from the expected payload size and did not include the overhead.
Make the code more explicit and get rid of the confusing
MAX_DATA_IN_READ_BUF define that hides details on buffer allocation
calculation from the code.
The device is already beeing de-initialised from the verify/enroll
commands. Trying it again will result in a timeout error as it is not
responding properly at that point.
And activate perimeter points removal if this flag is set
This flag should be set for aes1610, aesx660, aes2501, aes2550
and upektc_img since these sensors may produce incomplete image.

This step helps to drop false minutiae for short sensors and
it was accidentally dropped during NBIS update. Re-add this step
and add a patch to update script to ensure that it's not dropped
during next update.
Fixes: 9fb789dc78 ("nbis: Update to NBIS 5.0.0")
If a transfer errors out then actual_length is negative. The only error
that is not caught is a timeout error, which should also result in the
SSM to move to the next state.
For some reason static checkers report that the auto-free is not run if
the goto exists the loop. It seems to me like that should work fine, but
we can simply make the analysers happy by moving it.
We need more than 1 line for assembling, but in general, we should
have a reasonable amount of lines. So use the width in the hope we'll
get an image that is about square at least.
Closes: #135
When no driver is found for an USB device a debug message is
printed. However, it has PID and VID in wrong order - usually it
is Vendor ID which goes first. This is how 'lsusb' prints it.
Matching the order helps debugging.

In the fpi_print_fill_from_user_id() GDate is defined using
g_autoptr(). However, this requires new enough GLib. For older
versions there's a definition provided locally in fpi-compact.h.
Include the file to fix build with older version of GLib.

If we fail when setting the scanned image to a print, we'll have a fatal
error, in such case we can terminate the current action and deactivate the
device.
In some cases nbim's get_minutiae returns no minutiae without providing an
error code, and if this happens we would crash in the task callback function
as we would try to deference the data->minutiae pointer.

If the image height is less than the sensor horizontal resolution, then
return a retry error rather than trying to submit the image for further
processing.
Related to: #251
The minutiae detection might fail and we must not copy any data at that
point. So check g_task_had_error to ensure that we only do so when the
task was successful.

The public API uses gio and gobject header, ensure that these are in the
list of Required pkg-config modules, otherwise they are added to
Required.private which is not OK.
It appears the order of linking is relevant in this case, change it to
fix some linking issues.
It may be that there are better solutions to this problem.
Devices with no storage don't allow listing prints, and if we try to do
that, we'd end up in trying to call a NULL function pointer, causing a crash
So always check if the device has storage before calling the list vfunc, and
if we fail, return an error.
Include an unit-test to verify this situation
Without this we get warnings like the following:
cc1: warning: .../_build/libfprint/nbis/libfprint-include: No such file or directory [-Wmissing-include-dirs]
We are already using a number of defines and autoptrs from newer GLib
releases. Add the appropriate compatibility defines rather than removing
the corresponding code.
