https://bugzilla.redhat.com/show_bug.cgi?id=1047234 Add a range check for supported numa memory placement modes provided by the user before setting them in the domain definition. Without the check the user is able to provide a (yet) unknown mode which is then stored in the domain definition. This potentially causes a NULL dereference when the defintion is formatted into the XML. To reproduce run: virsh numatune DOMNAME --mode 6 --nodeset 0 The XML will then contain: <numatune> <memory mode='(null)' nodeset='0'/> </numatune> With this fix, the command fails: error: Unable to change numa parameters error: invalid argument: unsupported numa_mode: '6'
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
