Hello,
I was investigating bug report ad6c1104e51702ef591b on syzbot, and came
to the conclusion that it is intended behaviour. The repro.c file was
calling ioctl with the cmd as FBIOPUT_VSCREENINFO with an invalid yres
(8) so the kernel was returning -EINVAL, from the function
fbcon_modechange_possible. I am wondering is this intended behaviour,
due to something happening on the user's end, or should it be something
be implemented as a fallback?
Thanks,
Saad Varshani
