[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [Xen-devel] PATCH: 2/4: Revert current VNC auth support
This patch reverts the current Xen specific implementation of VNC authentication
from the QEMU code. This is basically reverting 11840:02506a744315. The idea
here is to get the VNC code back to more closely match upstream QEMU, before
applying the upstream auth patches.
