I would rather not provide a holistic sort function in the kernel for both IPv4 and IPv6 which would a requirement by glibc, no? > I still think most of the address sorting is bogus because it appears to > make guarantees which can break after renumbering. Yes, of course. Your patch for glibc looks fine to me, so Acked-by: Hannes Frederic Sowa <han...@stressinduktion.org> Bye, Hannes -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
