KVM instances on a 2.6.32 host kernel have broken IPv6 connectivity either by: a) Bridging and using Intel (hardware) NICs on the host *or* b) Routing their traffic through the host. due to two different, both related to GSO but otherwise unrelated bugs.
As mentioned in the patch mails to come, the bugs have been fixed by 8e1e8a4779cb23c1d9f51e9223795e07ec54d77a (2.6.35) and 0aa68271510ae2b221d4b60892103837be63afe4 (2.6.33) upstream, respectively. The commits didn't apply cleanly to 2.6.32 but their backporting was trivial with no algorithmic changes. The backported patches on top of longterm-2.6.32 have been in production with no problems for over two months now on a large fleet of machines. See the Debian #630730 bug for more context; David Miller replied there too. http://bugs.debian.org/630730 Regards, Faidon _______________________________________________ stable mailing list stable@linux.kernel.org http://linux.kernel.org/mailman/listinfo/stable
