Input/output error - termios.TIOCSTI

          Hey !

Because of TIOCSTI patch applied recently on Linux Kernel, we need to re-implement some Arsenal functions (which can take some time).
Thanks @slasheur7 helping at troubleshooting this.

Here is a workaround, execute as root :
sysctl -w dev.tty.legacy_tiocsti=1

If you want this workaround to survive a reboot, add the following configuration to sysctl.conf file (root permission needed) :
echo "dev.tty.legacy_tiocsti=1" >> /etc/sysctl.conf

It works on the current Kali 2023.4 (python 3.11.7 and 3.12.1) and should also work on other Linux distro.

Of course there is security concern (ie : if you are not already root on your Linux). More information about TIOCTSI in the following kernel commit log :

Is anyone working on this, I can have a look but I do not want to waste my time and effort.

Hi Tim,
we are not currently working on this issue because it seems that many changes are involved, but we'd be happy to hear your ideas.
