Hello,
Mickael Salaun made a proof of concept of a covert channel with a code written in C : xencc.c.
This code was writtten in 2009 and is accessible here : http://digikod.net/public/XenCC/"]http://digikod.net/public/XenCC/
This code permit to send data between 2 domU using Pseudo-physical memory with a driver created by xencc.
Can you say me :
- if you made a patch or a fix for this problem ?
- if yes, in which Xen version did you implement it ?
- if yes, by which manner (mecanism) did you fix this problem ?
Thanks in advance for your answers.
Regards.
