If you ran virsh in interactive mode and ran a command
that virsh could not parse, it would then SEGV
on subsequent commands. The problem is that we are
freeing the vshCmd structure in the syntaxError label
at the end of vshCommandParse, but forgetting to
set ctl->cmd to NULL. This means that on the next command,
we would try to free the same structure again, leading
to badness.
* tools/virsh.c: Make sure to set ctl->cmd to NULL after
freeing it in vshCommandParse()
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.
