Tools default to 1% lower threshold (tip up) and 5% upper threshold (tip
down). But our distance vs pressure exclusion would reset the distance
for *any* pressure value, regardless how low that value was and how high
distance was in comparison.
A very low pressure value of less than 1% would then result in a
normalized pressure of 0, so we'd effectively just reset the distance to
zero and do nothing with the pressure. This can cause distance jumps
when the tool arbitrarily sends low pressure values while hovering as
seen in https://github.com/libsdl-org/SDL/pull/5481#issuecomment-1118969064
Commit 61bdc05fb0 from Dec 2017
"tablet: set the tip-up pressure threshold to 1%"
was presumably to address this but no longer (?) works.
Fix this by addressing multiple issues at the same time:
- anything under that 1% threshold is now considered as zero pressure
and any distance value is kept as-is. Once pressure reaches 1%,
distance is always zero.
- axis normalization is now from 1% to 100% (previously: upper threshold
to 100%). So a tip down event should always have ~4% pressure and we
may get tablet motion events with nonzero pressure before the tip down
event.
From memory, this was always intended anyway since a tip event should
require some significant pressure, maybe too high compared to e.g.
pressure-sensitive painting
- where a tablet has an offset, add the same 1%/5% thresholds, on top of
that offset. And keep adjusting those thresholds as we change the
offset. Assuming that the offset is the absolute minimum a worn-out
pen can reach, this gives us the same behaviour as a new pen. The
calculation here uses a simple approach so the actual range is
slightly larger than 5% but it'll do.
Previously, the lower threshold for an offset pen was the axis minimum
but that can never be reached. So there was probably an undiscovered
bug in there.
And fix a bunch of comments that were either wrong, confusing or
incomplete, e.g. the pressure thresholds were already in device
coordinates.

tools/record: get rid of indent push/pop, replace with fixed indents
Introduced some magic to detect if there's a '-' at the start of the

string is constant though, leading to an indentation error when record
is run with --with-libinput.

This fixes a format string vulnerabilty.
evdev_log_message() composes a format string consisting of a fixed
prefix (including the rendered device name) and the passed-in format
buffer. This format string is then passed with the arguments to the
actual log handler, which usually and eventually ends up being printf.
If the device name contains a printf-style format directive, these ended
up in the format string and thus get interpreted correctly, e.g. for a
device "Foo%sBar" the log message vs printf invocation ends up being:
evdev_log_message(device, "some message %s", "some argument");
printf("event9 - Foo%sBar: some message %s", "some argument");
This can enable an attacker to execute malicious code with the
privileges of the process using libinput.
To exploit this, an attacker needs to be able to create a kernel device
with a malicious name, e.g. through /dev/uinput or a Bluetooth device.
To fix this, convert any potential format directives in the device name
by duplicating percentages.
Pre-rendering the device to avoid the issue altogether would be nicer
but the current log level hooks do not easily allow for this. The device
name is the only user-controlled part of the format string.
A second potential issue is the sysname of the device which is also
sanitized.
This issue was found by Albin Eldstål-Ahrens and Benjamin Svensson from
Assured AB, and independently by Lukas Lamster.

Since cd4f2f32b5 ("fallback: disable mouse scroll wheel while middle
button is pressed") the mouse wheel is inhibited while the mouse wheel
is pressed.
The original intention of this feature was to avoid unintended scroll
while pressing the scroll wheel. However, now that high-resolution
scroll is fully integrated in libinput we can improve this feature and
filter unintended scroll (below half a detent) and allow it when it is
intended (over half a detent).
Remove the "WHEEL_STATE_PRESSED" state from the wheel state machine and
let the general heuristics handle this case.
Also, remove the specific tests for this feature as now it is covered
by the general test cases.

The Wacom 524C device triggers a kernel bug in the InRange and Invert
handling. Every time BTN_TOUCH is set/unset the device also sets/unsets
BTN_TOOL_PEN even when we nominally have the eraser in proximity.
The event sequence effectively looks like this:
# on prox in
BTN_TOOL_RUBBER 1
-- SYN_REPORT ---
# on tip down
BTN_TOOL_PEN 1
BTN_TOUCH 1
-- SYN_REPORT ---
# on tip up
BTN_TOUCH 0
BTN_TOOL_PEN 0
-- SYN_REPORT ---
# on prox out
BTN_TOOL_RUBBER 1
-- SYN_REPORT ---
To work around this, bias our duplicate tool detection code towards the
eraser - if we have an eraser in-prox already and the pen goes
in-prox, ignore it and continue with the eraser. But if we have a pen
in-prox and the eraser goes in-prox as well, force a prox-out for the
pen and put the eraser in-prox.
