There was a double free issue caused by virSysinfoRead on s390, as the same manufacturer string instance was assigned to more than one processor record. Cleaned up other potential memory issues and restructured the sysinfo parsing code by moving repeating patterns into a helper function. The restructuring made it necessary to conditionally disable -Wlogical-op for some older GCC versions, using pragma GCC diagnostic. This is a GCC specific pragma, which is acceptable, since we're using it to work around a GCC specific bug. Finally, added a function virSysinfoSetup to configure the sysinfo data source files/script during run time, to facilitate writing test programs. This function is not published in sysinfo.h and only there for testing. Signed-off-by: Viktor Mihajlovski <mihajlov@linux.vnet.ibm.com>
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.
