FD passing APIs like CreateXMLWithFiles or OpenGraphicsFD will leak file descriptors. The user passes in an fd, which is dup()'d in virNetClientProgramCall. The new fd is what is transfered to the server virNetClientIOWriteMessage. Once all the fds have been written though, the parent msg->fds list is immediately free'd, so the individual fds are never closed. This closes each FD as its send to the server, so all fds have been closed by the time msg->fds is free'd. https://bugzilla.redhat.com/show_bug.cgi?id=1159766 (cherry picked from commit 5ba48584fbc5079c0ddbc9e9a52c96d7bcef0761)
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.
