Acpid 事件被 SELinux 拒绝,如何在不打开安全漏洞的情况下安全地允许该事件?

Acpid 事件被 SELinux 拒绝,如何在不打开安全漏洞的情况下安全地允许该事件?

我在我的新笔记本(Lenovo Yoga Pad)上安装了 Fedora(3.17.2-200.fc20.x86_64),并希望添加此脚本以在我翻转屏幕时触发。事件触发的脚本位于 root/etc/acpi/actions并由 root 拥有。

问题:当我翻转屏幕时,除了 SELinux 告诉我不同​​的警告(例如访问被拒绝,一些关于 ioctl 和读取的内容等,我无法正确回忆起来)之外,什么也没发生。无论如何,它告诉我运行grep tablet_mode.ori /var/log/audit/audit.log | audit2allow -M mypolsemodule -i mypol.pp修复它,我这样做了,但重新启动后,当我翻转屏幕时什么也没有发生。现在,我删除了主目录中的 mypol 文件,因为我认为我可以再次查看 SELinux 输出。

我现在陷入困境,我害怕在我的 SELinux 中打开安全漏洞,对此的正确解决方案是什么?有趣的是,当我重新启动 acpid 并sudo killall acpid && sudo acpid触发事件并起作用时,在这种情况下唯一不起作用的是 gsettings 命令,它不会显示任何错误,但不会更改我的用户(toor)。

这是由事件触发的脚本:

#!/bin/bash

su toor -c "/home/toor/backup/scripts/toggle_keyboard.sh"
touchpad=$(xinput list-props "SynPS/2 Synaptics TouchPad" | grep "Device Enabled" | awk -F ":" '{print $2}')
if [ $touchpad -eq 1 ]; then
    /home/toor/backup/scripts/rotate.sh inverted
    xinput --set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 0
else
    /home/toor/backup/scripts/rotate.sh normal
    xinput --set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 1
fi

这是rotate.sh:

#!/bin/bash

current_orientation(){
    xrandr|grep " connected" |awk '{print $4}'
}
rotate_left(){
    xrandr -o left
    xsetwacom set "Wacom ISDv4 EC Pen stylus" rotate ccw
        xsetwacom set "Wacom ISDv4 EC Pen eraser" rotate ccw
    xinput set-prop "ELAN Touchscreen" "Coordinate Transformation Matrix" 0 -1 1 1 0 0 0 0 1
}
rotate_right(){
    xrandr -o right
    xsetwacom set "Wacom ISDv4 EC Pen stylus" rotate cw
        xsetwacom set "Wacom ISDv4 EC Pen eraser" rotate cw
    xinput set-prop "ELAN Touchscreen" "Coordinate Transformation Matrix" 0 1 0 -1 0 1 0 0 1
}
rotate_inverted(){
    xrandr -o inverted
    xsetwacom set "Wacom ISDv4 EC Pen stylus" rotate half
        xsetwacom set "Wacom ISDv4 EC Pen eraser" rotate half
    xinput set-prop "ELAN Touchscreen" "Coordinate Transformation Matrix" -1 0 1 0 -1 1 0 0 1
}
rotate_normal(){
    xrandr -o normal
    xsetwacom set "Wacom ISDv4 EC Pen stylus" rotate none
        xsetwacom set "Wacom ISDv4 EC Pen eraser" rotate none
    xinput set-prop "ELAN Touchscreen" "Coordinate Transformation Matrix" 1 0 0 0 1 0 0 0 1
}

orientation=$(current_orientation)

# if the orientation argument was given to this script, sets orientation variable
# according to the way we want to rotate in next loop.
if [ -n "$1" ]; then
    if [ "$1" == "normal" ]; then
        orientation="right"
    fi
    if [ "$1" == "left" ]; then
        orientation="(normal"
    fi
    if [ "$1" == "right" ]; then
        orientation="inverted"
    fi
    if [ "$1" == "inverted" ]; then
        orientation="left"
    fi
fi

# turns 90° counter-clockwise
case $orientation in
    "(normal" )
        rotate_left
        ;;
    "inverted" )
        rotate_right
        ;;
    "right" )
        rotate_normal
        ;;
    "left" )
        rotate_inverted
        ;;
    * )
        echo "it fucked up"
        exit 1
        ;;
esac

exit 0

这将是toggle_keyboard.sh

#!/bin/bash
# toggle onboard keyboard

obk=$(gsettings get org.gnome.desktop.a11y.applications screen-keyboard-enabled)

if [ $obk == 'false' ]; then
        gsettings set org.gnome.desktop.a11y.applications screen-keyboard-enabled true
else
        gsettings set org.gnome.desktop.a11y.applications screen-keyboard-enabled false
fi

希望你能帮我解决这个问题,我很感激任何帮助
