Although the upper-layer code protected against it, it was possible to call iptablesForwardMasquerade() with an IPv6 address and have it attempt to add a rule to the MASQUERADE chain of ip6tables (which doesn't exist). This patch changes that function to check the protocol of the given address, generate an error log if it's not IPv4 (AF_INET), and finally hardcodes all the family parameters sent down to lower-level functions.
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.
