#2301 fixed DF variable out of sync with RFLAGS after the SYSCALL instruction Jakub Jermar
Description

Masking off the DF flag from the RFLAGS register during the SYSCALL instruction by specifying the DF bit in the SFMASK register doesn't work because the DF variable doesn't get updated. This bug allows a malicious userspace code to damage kernel memory on systems which rely on proper functionality of the SYSCALL instruction and the SFMASK register. Note that the same bug existed in qemu and was fixed in revision 4120:

#2302 fixed keys dead when remapped by xkb -> fixed in SVN Clemens Fruhwirth
Description

Xorg supports remapping keys via xkb. A typical way would be:

                Option            "CoreKeyboard"
                Option            "XkbRules"      "xorg"
                Option            "XkbModel"      "pc105"
                Option            "XkbLayout"    "us"
                Option            "XkbOptions"  "therp:desktop"

Additionally we put the following line into /etc/X11/xkb/rules/base (or xorg in the same dir):

therp:desktop         =       +therp(desktop)

This teaches Xorg to treat the option string "therp:desktop" namely by resolving it to +therp(desktop).

Further we need to add the line

--p----- -m------ therp(desktop)

to /etc/X11/xkb/symbols.dir

And finally add a file called therp to /etc/X11/xkb/symbols with the following content:

partial modifier_keys 
xkb_symbols "desktop" {
    key <AD11>  {  symbols[Group1]= [ parenleft, braceleft ] };
    key <AD12>  {  symbols[Group1]= [ parenright, braceright ] };
    key <AE09> { symbols[Group1]= [         9,    bracketleft       ]       };
    key <AE10> { symbols[Group1]= [         0,    bracketright      ]       };
};

The effect of these lines is that the keys () and [] are swapped on the keyboard. I personally like that as I type round brackets more often and I like them to be accessible without the Shift modifier key.

However, as soon as a key is touched by xkb, it goes dead for VirtualBox. Notice that 0 and 9 wasn't changed, however 0 and 9 don't work even unshifted.

To make it work I have to adjust the layouts manually in the vbox source code and supply vbox with a keymap that resembles my remappings precisely.
