usb-transfer: Work around libgusb cancellation issue

We have plenty of code paths where a transfer may be cancelled before it is submitted. Unfortunately, libgusb up to and including version 0.3.6 are not handling that case correctly (due to libusb ignoring cancellation on transfers that are not yet submitted). Work around this, but do so in a somewhat lazy fashion that is not entirely race free. Closes: #306

 This file lists notable changes in each release. For the full history of all
 changes, see ChangeLog.

+2020-06-08: v1.90.3 release
+
+This release mostly contains support for a number of new match-on-chip
+devices. Most notable is the addition of the new goodixmoc driver.
+Currently the driver has the small caveat that we have no strategy to
+garbage collect old prints yet (a simple strategy could be implemented
+in fprintd).
+
+Highlights:
+ * New goodixmoc driver supporting Goodix USB devices:
+   27C6:5840
+   27C6:6496
+   27C6:60A2
+ * Newly added support for Synaptics device:
+   06CB:00E9
+   06CB:00DF
+ * Fixed an issue with Synaptics devices sometimes not working at boot
+ * Fix issue with aes3k driver (#306)
+
+2020-06-08: v1.90.2 release
+
+This release contains a large amount of bug and regression fixes. These
+are not listed explicitly, but affect the majority of drivers.
+
+Highlights:
+ * A patch for nbis required for some sensors was accidentally dropped in
+   an earlier release. Users of these sensors/drivers (aes1610, aes2501,
+   aes2550, aes1660, aes2660, elan, upektc_img) need to re-enroll (#142).
+
 2019-11-20: v1.90.1 release

 This release fixes a lot of the regressions introduced in 1.90.0. Please note

+`umockdev` Tests
+================
+`umockdev` tests use fingerprint devices mocked by [`umockdev`
+toolchain][umockdev].
+
+This document describes how to create a 'capture' test: a test that
+captures a picture of a fingerprint from the device (mocked by
+`umockdev`) and compares it with the standard one.
+
+Other kinds of `umockdev` tests could be created in a similar manner.
+
+
+'Capture' Test Creation
+-----------------------
+A new 'capture' test is created by means of `capture.py` script:
+
+1. Create (if needed) a directory for the driver under `tests`
+   directory:
+
+   `mkdir DRIVER`
+
+2. Prepare your execution environment.
+
+   In the next step a working and up to date libfprint is needed. This can be
+   achieved by installing it into your system. Alternatively, you can set
+   the following environment variables to run a local build:
+   - `export LD_PRELOAD=<meson-build-dir>/libfprint/libfprint-2.so`
+   - `export GI_TYPELIB_PATH=<meson-build-dir>/libfprint`
+
+   Also, sometimes the driver must be adopted to the emulated environment
+   (mainly if it uses random numbers, see `synaptics.c` for an example).
+   Set the following environment variable to enable this adaptation:
+   - `export FP_DEVICE_EMULATION=1`
+
+   Run the next steps in the same terminal.
+
+3. Find the real USB fingerprint device with `lsusb`, e.g.:
+
+   `Bus 001 Device 005: ID 138a:0090 Validity Sensors, Inc. VFS7500 Touch Fingerprint Sensor`
+
+   The following USB device is used in the example above:
+   `/dev/bus/usb/001/005`.
+
+4. Record information about this device:
+
+   `umockdev-record /dev/bus/usb/001/005 > DRIVER/device`
+
+5. Record interaction of `capture.py` (or other test) with the device:
+
+   `umockdev-record -i /dev/bus/usb/001/005=DRIVER/capture.ioctl -- python3 ./capture.py DRIVER/capture.png`
+
+   Files `capture.ioctl` and `capture.png` will be created as the
+   result of this command.
+
+6. Add driver's name to `drivers_tests` in the `meson.build`.
+7. Check whether everything works as expected.
+
+**Note.** To avoid submitting a real fingerprint, the side of finger,
+arm, or anything else producing an image with the device can be used.
+
+
+Possible Issues
+---------------
+`umockdev-record` aggressively groups URBs. In most cases, manual
+intervention is unfortunately required. Often, drivers do a chain of
+commands like: A then B each with a different reply. However,
+`umockdev-record` could create a file like this:
+
+    A
+     reply 1
+     reply 2
+    B
+     reply 1
+     reply 2
+
+In that case, records must be re-ordered:
+
+    A
+     reply 1
+    B
+     reply 1
+    A
+     reply 2
+    B
+     reply 2
+
+Other changes may be needed to get everything working. For example the
+`elan` driver relies on a timeout that is not reported correctly. In
+this case the driver works around it by interpreting the protocol
+error differently in the virtual environment (by means of
+`FP_DEVICE_EMULATION` environment variable).

Benjamin Berg	c7cab77fc1	usb-transfer: Work around libgusb cancellation issue We have plenty of code paths where a transfer may be cancelled before it is submitted. Unfortunately, libgusb up to and including version 0.3.6 are not handling that case correctly (due to libusb ignoring cancellation on transfers that are not yet submitted). Work around this, but do so in a somewhat lazy fashion that is not entirely race free. Closes: #306	2020-10-01 00:19:35 +02:00
Benjamin Berg	a63dcc96d5	virtual_image: Open a window for race conditions during open/close Delay the open/close callbacks by 100ms so that we have a window of opportunity for race conditions. This is needed to test certain conditiosn in fprintd.	2020-09-29 12:02:19 +00:00
Benjamin Berg	fab349f356	Remove trailing \n where they are not necessary Adding a trailing \n to g_message, g_debug, g_warning and g_error is not neccessary, as a newline will be added automatically by the logging infrastructure.	2020-09-29 10:42:03 +02:00
Benjamin Berg	62edf93958	tests: Add AES3500 test case Thanks for Federico Cupellini for providing test samples.	2020-09-29 10:35:48 +02:00
Benjamin Berg	8c4ff253cb	aes3k: Fix transfer error path and cancellable lifetime The cancellable needs to be free'ed at deactivation. Also free it if we run into a fatal error, which then in turn indicates that the device is deactivated already.	2020-09-29 10:35:25 +02:00
Benjamin Berg	3ce6a15547	image-device: Don't deactivate if deactivation was already started The test only prevent deactivation after it completed. Also guard against trying to deactivate a second time.	2020-09-28 19:12:28 +02:00
Benjamin Berg	174aa2c091	Release 1.90.3	2020-09-14 14:23:45 +02:00
Benjamin Berg	9efe25b91c	ci: Disable flatpak building for forks Also move to use a single rules set for flatpak rather than only/except rules.	2020-09-14 14:17:25 +02:00
Benjamin Berg	bcce8876e2	aes3k: Fix cancellation logic of aes3k driver The change_state function is called synchronously from the image_captured callback. This means that deactivation of the device happens during the img_cb function, causing the USB transfer to be re-registered even though the device is already deactivating. There are various ways to fix this, but it makes sense to directly bind the cancellation to the deactivation. So create a cancellable that we cancel at deactivation time, and make sure we always deactivate by going through cancellation. closes: #306	2020-09-14 11:23:38 +00:00

Benjamin Berg	ce6961d165	image-device: Fix cancellation documentation Image devices are simply deactivated suddenly. As such, the cancellation logic of FpDevice is not really useful there, but the documentation was apparently accidentally copied unmodified.	2020-09-07 12:12:34 +02:00

Benjamin Berg	5d0481b031	context: Lower severity of warning if USB fails to initialise This is unlikely to happen in a real world scenario and currently breaks running the CI test (not the umockdev based ones) while building the flatpak. Lower the severity to avoid aborting because there is a warning.	2020-09-03 09:41:11 +02:00
Benjamin Berg	596d22a449	context: Fix invalid accesses to GUsbContext if USB is missing When USB cannot be initialised (inside the flatpak build environment), then we would have invalid accesses to the NULL pointer. Fix those.	2020-09-03 09:41:11 +02:00

Benjamin Berg	4b2816db64	Update for 1.90.2	2020-06-08 11:40:02 +02:00
Benjamin Berg	4af3e59174	uru4000: Always detect whether encryption is in use 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.	2020-06-05 15:53:53 +00:00

Vasily Khoruzhick	d276c3489e	upeksonly: Fix register write value The value was set after the transfer was submitting, causing the value to always be zero.	2020-06-05 17:44:36 +02:00
Benjamin Berg	3f51e6dcb6	upeksonly: Pass required user data to write_regs_cb The user data for write_regs_cb needs to be set to wrdata. This was simply missing, add the appropriate argument.	2020-06-05 17:44:36 +02:00
Benjamin Berg	b4dbbd667a	upeksonly: Avoid reading beyond received packet boundary 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.	2020-06-05 17:44:36 +02:00
Benjamin Berg	7d9245505f	upeksonly: Remove callback support after killing transfers This seems to have been unused even before the v2 port.	2020-06-05 17:44:36 +02:00
Benjamin Berg	570daf2321	upeksonly: Remove ABORT_SSM constant 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.	2020-06-05 15:40:17 +00:00
Benjamin Berg	60d0f84294	upeksonly: Fix creation of image transfers 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. Co-authored-by: Vasily Khoruzhick <anarsoul@gmail.com>	2020-06-05 15:40:17 +00:00
Benjamin Berg	6633025437	vfs301: Allow freeing of data by copying it 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.	2020-06-05 15:17:42 +00:00
Benjamin Berg	40ed353666	elan: Only queue state changes once 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	2020-06-05 15:13:18 +00:00
Benjamin Berg	32bdd8d5c4	image: Fix reporting of retry on activation timeout 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.	2020-06-05 15:07:05 +00:00
Benjamin Berg	ec4fc9aec5	ci: Put coverage regexp into CI description One can set it in the project, but that doesn't get copied to forks. And that means the coverage information isn't printed in MRs sometimes. Just add it into .gitlab-ci.yml so that it always works.	2020-06-05 15:03:38 +00:00
