Hi -stable team,
please backport the commit f1aa2eb5ea05 ("sysctl: fix proc_dobool() usability")
to the stable kernels containing commit 83efeeeb3d04 ("tty: Allow TIOCSTI to be disabled").
(Which seems only to be the 6.2 branch only at the moment)
Without this backport the sysctl dev.net.legacy_tiocsti to enable
ioctl(TIOCSTI) is not functional. So on kernels that don't enable
CONFIG_LEGACY_TIOCSTI, ioctl(TIOCSTI) is not usable at all.
This ioctl is used for the copy-and-paste functionality of the
screenreader "fenrir".
