GLibC has a really complicated way of dealing with the 'stat' function historically, which means our mocks in turn have to look at four different possible functions to replace, stat, stat64, __xstat, __xstat64. In Fedora 33 and earlier: - libvirt.so links to __xstat64 - libc.so library exports stat, stat64, __xstat, __xstat64 - sys/stat.h header exposes stat and __xstat In Fedora 34 rawhide: - libvirt.so links to stat64 - libc.so library exports stat, stat64, __xstat, __xstat64 - sys/stat.h header exposes stat Historically we only looked at the exported symbols from libc.so to decide which to mock. In F34 though we must not consider __xstat / __xstat64 though because they only existance for binary compatibility. Newly built binaries won't reference them. Thus we must introduce a header file check into our logic for deciding which symbol to mock. We must ignore the __xstat / __xstat64 symbols if they don't appear in the sys/stat.h header, even if they appear in libc.so Signed-off-by: Daniel P.

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.
