Strictly speaking, xdrproc_t is declared as following: typedef bool_t (*xdrproc_t)(XDR *, ...); But our rpcgen generates properly typed functions, e.g.: bool_t xdr_virNetMessageError(XDR *xdrs, virNetMessageError *objp) Now, these functions of ours are passed around as callbacks (via an argument of xdrproc_t type), for instance in virNetMessageEncodePayload(). But these two types are strictly different. We silence the compiler by typecasting the callbacks when passing them, but strictly speaking - calling such callback later, when a function of xdrproc_t is expected is an undefined behavior. Ideally, we would fix our rpcgen to generate proper function headers, but: a) my brain is too small to do that, and b) we would lose compiler protection if an xdr_*() function is called directly but argument of a wrong type is passed. Silence UBSAN for now. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Daniel P. Berrangé <berrange@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>
Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
