fba3e682ea elan: Remove supported devices from udev whitelist 2018-08-09 14:45:15 +02:00

bccff4ffef elan: Change command structs, support more devices 
Make each command a separate struct to get finer control over which
commands are called on which devices. Update ssm's accordingly. Add
sensor_reset and fuse_load commands.

Support 0x0903, 0x0c03, 0x0c16, 0x0c1a, 0x0c26

19e7b217c1 lib: Downgrade fp_err() to be non-fatal 
Similarly to b1ac865abd, downgrade
fp_err() to be non-fatal. A number of drivers would spit out an error
when encountering this call, but not crash, carry on and most of the
time recover.

Make sure we don't assert in those cases.

b1ac865abd lib: Downgrade BUG* assertions to work-around crashes 
BUG() and BUG_ON() didn't use to assert, but only print an error if
debugging was enabled. This was hiding a lot of state bugs in drivers,
and transforming those into assertions causes crashes.

Downgrade the assertion to only print a warning, and hope that those
eventually get fixed in the drivers so we can re-enable them.

c91819f551 lib: Remove drv->close absence support in fp_async_dev_close() 
The driver will at least need to close its hardware resources, and
free memory, so it must have had one.

This case was never actually used as can be seen from the fact that
we would assert in fpi_drvcb_close_complete() if the state was wrong
but never set it to the expected value.

0215483fb3 assembling: Fix assembling of last frame in reverse mode

37bb59df13 assembling: Fix assembling of frames for non-reverse stripes 
Every frame stores the delta from the previous frame, in reverse mode
it stores the delta to the next frame. This causes images to use the
wrong delta while assembling in forward mode.

The broken assembling in forward mode will create a small error for
linear motion, because the delta of all frames is approximately the
same in this case. But if you move your finger, stop and then continue
moving in a single scan, the misplaced frames should be visible in
the assembled output.

This could result in false positives and verification failing.

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

d8aae30a67 aes2501: Harden against low finger pressure 
Wait for 3 empty frames before stopping the scan

The driver used to stop the scan immediately after an empty frame
(by checking for hist sum == 0), but it is possible to get empty
frames in the middle of the scan due to low finger pressure.
Waiting for 3 empty frames stop the driver wrongly aborting the scan
too early.

ff842125c5 Add C++ guards to take care of C++ name-mangling. 
The libfprint library is generally built with C calling conventions.
Which makes it difficult to link to C++ programs as it is.

This patch adds the support for linking with C++ code - by telling the C++
compiler to use C calling conventions for libfprint functions.

25161286f5 Only complete scan with MIN_ROWS in print 
Don't consider the scan complete unless theres at least
MIN_ROWS recorded or very long blank read occurred.

Typical problem spot: one brief touch before starting the
actual scan. Happens most commonly if scan is started from
before the first joint resulting in a gap after the inital touch.

df4a6f53d2 Rework "discover" code for drivers 
Check all the drivers for one that'll drive our device in

successfully to a driver without such a method.

This allow drivers to both reject devices (if 2 drivers handle
the same USB IDs), or a single driver to handle variants of the
same device (through the devtype out value of the discover method).
