The purpose of ERROR() macro in our NSS module is to print error message provided as arguments followed by error string corresponding to errno. Historically, we've used strerror_r() for that (please note, we want our NSS module to be free of libvirt internal functions, or glib even - hence, g_strerror() is off the table). Now strerror_r() is documented as: Returns ... a pointer to a string that the function stores in buf, or a pointer to some (immutable) static string (in which case buf is unused). Therefore, we can't rely the string being stored in the buf and really need to store the retval and print that instead. While touching this area, decrease the ebuf size, since its current size (1KiB) is triggering our stack limit (2KiB) in some cases.

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.
