There is a race condition in current Xorg server releases which leads to
crashes when using easytroke for mouse gestures.
While testing Debian 12 on an old Acer laptop with easystroke running I
noticed frequent Xorg crashes while browsing in chromium. The crashes, when
they happen, appear to be triggered by a page scroll with the mouse wheel
(black screen, return to lightdm login screen). There is nothing specific
about chromium actually: it happens with firefox too, and sometimes even
while scrolling text in mate-terminal. Although they look random at first
(scrolling works for a number of minutes before crashing), i found it's
pretty easy to reproduce by stressing the system:
- open 5-6 tabs in chromium.
- make system busy (reload tabs / run some other cpu-intensive task ...)
- quickly switch between tabs and scroll pages as much as you can with the
mouse wheel (switch tab, move mouse back to center, wheel scroll)
Best way to produce a crash seems to be when chromium is lagging so much
behind that it hasn't processed the tab switch yet, but you're already
scrolling the page, flooding it with scroll events. I can usually make
it crash within 30s when doing this (this is probably a lot easier to do on
an old laptop with slow cpu).
The queueing of events seems to cause Xorg some trouble as a number of
warnings pile up in /var/log/Xorg.0.log before a crash:
[ 45850.500] [Xi] Too many valuators reported for device 'Virtual core
pointer'. Ignoring event.
[ 45851.548] [Xi] Too many valuators reported for device 'Virtual core
pointer'. Ignoring event.

[ 45871.092] [Xi] Too many valuators reported for device 'Virtual core
pointer'. Ignoring event.
I believe upstream is aware of the issue as there is a fix for it in the
master branch (dc7cb45 2022-01-04 dix: Hold input lock for AttachDevice()),
however it is missing in the release branch so even latest upstream release
xorg-server-21.1.13 is affected. Debian bullseye, bookworm, testing and
unstable packages are all affected (haven't checked earlier versions).
Adding commit on top of debian bookworm xserver-xorg-core_21.1.7-3+deb12u7
package fixed the issue.
Notes:
- Reproducing crash:
These tabs work reasonably well for me: (for switching back and forth)

- Stack trace:
It typically crashes in miPointerSetPosition(), either directly or in
point_on_screen() which it calls.

Block was alloc'd by thread #1
The steps to trigger the race are:
1. Main thread does cleanup at mipointer.c:360 setting the slave device's
miPointerPtr to null.
2. Input thread use MIPOINTER in mipointer.c and get the slave's
miPointerPtr = null.
3. Main thread updates dev->master at devices.c:2609.
4. MIPOINTER would now return the master's miPointerPtr but the input
thread already got the slave's miPointerPtr in step 2 and segfaults by
null ptr deref.
