- don't fail the build on s390x test results, upstream stated that
fixing those is low priority for them since there is no real
usecase for fingerprint authentification on that architecture.
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.
Closes: #222
To avoid conflicts with previous libfprint version and make sure that the
target version is the correct one (plus to allow parallel install in some
distros), let's use a versioned naming for the library keeping the abi
version in sync.
Fixes#223
The callback function would continue processing even after having failed
the SSM already. This causes further invalid operations on the SSM.
This error was found using a coverity scan.
When quickly scanning a finger with the synaptic driver, it may wait forever
for finger removal even if this has already happened.
In fact we don't take care of the finger status when reporting the
verification.
To avoid this, add a function that delays the completion of the verification
until the finger removal if the finger is on sensor, otherwise it just
performs it.
Fixes#228
Remove the never-used cmd_complete_data value and the repetition of
cmd_complete_error.
In fact now as per the fpi_device_verify_report() usage, we already pass
the match information to the device, such as the error and it will be
they will be used on completion if needed.
This allows to simplify cmd_ssm_done() as well.
In some cases we want to complete the verification after that the finger has
been removed, but we still need to promptly report the match state otherwise
fpi-device will complain about, and will eventually cause a match error
instead that reporting a non-match:
synaptics: Finger is now on the sensor
synaptics: Received message with 0 sequence number 0x91, ignoring!
synaptics: interrupt transfer done
synaptics: delaying match failure until after finger removal!
synaptics: interrupt transfer done
device: Driver reported successful verify complete but did not report the
result earlier. Reporting error instead
libfprint: Failed to verify print: An unspecified error occured!
Fixes#227
The g_object_new call had a NULL argument for a property. This meant
that the compiler could not warn about the lack of NULL termination for
the argument list.
Add the missing NULL termination.
