FreeBSD and OpenBSD have a <net/if.h> that is not self-contained; and mingw lacks the header altogether. But gnulib has just taken care of that for us, so we might as well simplify our code. In the process, I got a syntax-check failure if we don't also take the gnulib execinfo module. * .gnulib: Update to latest, for execinfo and net_if. * bootstrap.conf (gnulib_modules): Add execinfo and net_if modules. * configure.ac: Let gnulib check for headers. Simplify check for 'struct ifreq', while also including enough prereq headers. * src/internal.h (IF_NAMESIZE): Drop, now that gnulib guarantees it. * src/nwfilter/nwfilter_learnipaddr.h: Use correct header for IF_NAMESIZE. * src/util/virnetdev.c (includes): Assume <net/if.h> exists. * src/util/virnetdevbridge.c (includes): Likewise. * src/util/virnetdevtap.c (includes): Likewise. * src/util/logging.c (includes): Assume <execinfo.h> exists. (virLogStackTraceToFd): Handle gnulib's fallback implementation.
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.
