This is based on the patch and observation from Bastien that some
URU4000B devices do not use encryption by default (it is a configuration
stored within the firmware). As such, it makes sense to always detect
whether encryption is in use by inspecting the image.
The encryption option would disable flipping of the image for the
URU400B device. Retain this behaviour for backward compatibility.
The code would just read 4096 bytes from the packet, without checking
the size and neither setting short_is_error. It is not clear whether
packets from the device are always 4096 bytes or not. But the code
assume we always get a full line, so enforce that and use the actual
packet size otherwise.
This was not used. The old driver used this if creating a USB transfer
failed, however, we delay any such failures (which cannot really happen)
into the callback today, where the error is handled differently.
The GPtrArray needs to be created at some point. Also, reference
counting was wrong as submitting the transfer sinks the ref, but we rely
on it surviving.
Note that we really should change this to only have one in-flight
transfer and starting a new one after it finishes.

When sending static data, it would not be copied. The function that
sends it assumed that it should be free'ed though.
Fix this by simply always making a copy.
The driver would warn about the fact that a state change is queued, but
still queue it a second time. This would result in deactivation to run
twice.
See: #216
The image driver may still be deactivating when a new activation request
comes in. This is because of a hack to do early reporting, which is
technically not needed anymore.
Fix the immediate issue by properly reporting the retry case. The proper
fix is to only finish the previous operation after the device has been
deactivated.
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.
Related to: #251
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.
