a6d0dbba95 lib/crc: remove unnecessary prompt for CONFIG_CRC_T10DIF
All modules that need CONFIG_CRC_T10DIF already select it, so there is no
need to bother users about the option.

8d355b56f2 selftests/hid: fix kfunc inclusions with newer bpftool
bpftool now embeds the kfuncs definitions directly in the generated
vmlinux.h

This is great, but because the selftests dir might be compiled with
HID_BPF disabled, we have no guarantees to be able to compile the
sources with the generated kfuncs.

If we have the kfuncs, because we have the `__not_used` hack, the newly
defined kfuncs do not match the ones from vmlinux.h and things go wrong.

Prevent vmlinux.h to define its kfuncs and also add the missing `__weak`
symbols for our custom kfuncs definitions

Linus Torvalds
919464deec Revert "HID: bpf: allow write access to quirks field in struct hid_device"
This reverts commit 6fd47effe9, and the related self-test update
commit e14e0eaeb0 ("selftests/hid: add test for assigning a given
device to hid-generic").

It results in things like the scroll wheel on Logitech mice not working
after a reboot due to the kernel being confused about the state of the
high-resolution mode.

Quoting Benjamin Tissoires:
 "The idea of 6fd47effe9 was to be able to call hid_bpf_rdesc_fixup()
  once per reprobe of the device.

  However, because the bpf filter can now change the quirk value, the
  call had to be moved before the driver gets bound (which was
  previously ensuring the unicity of the call).

  The net effect is that now, in the case hid-generic gets loaded first
  and then the specific driver gets loaded once the disk is available,
  the value of ->quirks is not reset, but kept to the value that was set
  by hid-generic (HID_QUIRK_INPUT_PER_APP).

  Once hid-logitech-hidpp kicks in, that quirk is now set, which creates
  two inputs for the single mouse: one keyboard for fancy shortcuts, and
  one mouse node.

  However, hid-logitech-hidpp expects only one input node to be attached
  (it stores it into hidpp->input), and when a wheel event is received,
  because there is some processing with high-resolution wheel events,
  the wheel event is injected into hidpp->input.

  And of course, when HID_QUIRK_INPUT_PER_APP is set, hidpp->input gets
  the keyboard node, which doesn't have wheel event type, and the events
  are ignored"

fe05c40ca9 selftest: hid: add the missing tests directory
Commit 160c826b4d ("selftest: hid: add missing run-hid-tools-tests.sh")
has added the run-hid-tools-tests.sh script for it to be installed, but
I forgot to add the tests directory together.

If running the test case without the tests directory,  will results in
the following error message:

    make -C tools/testing/selftests/ TARGETS=hid install \
	    INSTALL_PATH=$KSFT_INSTALL_PATH
    cd $KSFT_INSTALL_PATH

I got a weird verifier error with a subprog once, so let's have a test
for it.

d7696738d6 selftests/hid: convert the hid_bpf selftests with struct_ops
We drop the need for the attach() bpf syscall, but we need to set up
the hid_id field before calling __load().

The .bpf.c part is mechanical: we create one struct_ops per HID-BPF
program, as all the tests are for one program at a time.

51de9ee0a6 selftests/hid: add Huion Kamvas Pro 19 tests
This tablets gets a lot of things wrong:
- the secondary button is reported through Secondary Tip Switch
- the third button is reported through Invert

We need to add some out of proximity intermediate state when moving
back and forth with the eraser mode as it can only be triggered by
physically returning the pen, meaning that the tolerated transitions
can never happen.

03899011df selftests/hid: tablets: add a couple of XP-PEN tablets
Those tablets don't need special initialization, but are reporting
the events with the wrong usages:
- tip switch is used when the eraser should be used
- eraser is used instead of the secondary barrel switch

Add tests for those so we don't regress in the future.

Currently we set x/y tilt to 0 to not trigger the bpf program
compensate_coordinates_by_tilt()

e14d88d9b8 selftests/hid: tablets: reduce the number of pen state
All the *_WITH*BUTTON states were almost identical except for the
button itself.

I need to add a new device with a third button, and adding a bunch of
states is going to be quite cumbersome.

So convert the `button` parameter of PenState as a boolean, and store
which button is the target as an argument to all functions that need it.

The device is exported with a fuzz of 4, meaning that the `+ t` here
is removed by the fuzz algorithm, making those tests failing.

Not sure why, but when I run this locally it was passing, but not in the

98e20e5e13 bpfilter: remove bpfilter
bpfilter was supposed to convert iptables filtering rules into
BPF programs on the fly, from the kernel, through a usermode
helper. The base code for the UMH was introduced in 2018, and
couple of attempts (2, 3) tried to introduce the BPF program
generate features but were abandoned.

bpfilter now sits in a kernel tree unused and unusable, occasionally
causing confusion amongst Linux users (4, 5).

As bpfilter is now developed in a dedicated repository on GitHub (6),
it was suggested a couple of times this year (LSFMM/BPF 2023,
LPC 2023) to remove the deprecated kernel part of the project. This
is the purpose of this patch.

b0fb904d07 HID: wacom: Add additional tests of confidence behavior
Test for proper driver behavior when the touch confidence bit is set
or cleared. Test the three flavors of touch confidence loss (tipswitch
cleared before confidence, tipswitch and confidence cleared at the same
time, and tipswitch only cleared when touch is actually removed). Also
test two flavors of touch confidence gain (confidence added to a touch
that was "never" confident, and confidence added to a touch that was
previously confident).
