ping -6 works for me. As does ssh and https. I have native routable IPv6 on my home network provided by my ISP and it works fine on 4.18.x $ ping -6 google.com PING google.com(prg03s06-in-x0e.1e100.net (2a00:1450:4014:80d::200e)) 56 data bytes 64 bytes from prg03s06-in-x0e.1e100.net (2a00:1450:4014:80d::200e): icmp_seq=1 ttl=52 time=27.1 ms 64 bytes from prg03s06-in-x0e.1e100.net (2a00:1450:4014:80d::200e): icmp_seq=2 ttl=52 time=27.3 ms 64 bytes from prg03s06-in-x0e.1e100.net (2a00:1450:4014:80d::200e): icmp_seq=3 ttl=52 time=27.7 ms This works across x86/arm/aarch664 for me I seem to have the same problem, also on Talos P9. I'm running radvd on my router/firewall and while a x86_64 F-28 box got the network prefix after starting the died daemon (and has now valid global ipv6 address), my Talos shows only the default link scope address still. my Talos runs rawhide nodebug kernel 4.19.0-0.rc3.git0.1.fc30.ppc64le sounds like an issue with kernel 4.18+ (maybe 4.17+), because my old F-28 ppc64le install with 4.16 kernel was to talk IPv6 and it's not Power9 or Talos specific, I've reproduced it also on Power8, both physical and virtual hw. And looks specific to ppc64le, F-28 ppc64 with 4.18 kernel works correctly. So Michal found https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e9c4943a107b56696e4872cdffdba6b0c7277c77 as potential culprit and I've found https://lore.kernel.org/patchwork/patch/983905/ (from https://lists.ozlabs.org/pipermail/linuxppc-dev/2018-September/177952.html) as a proposed fix ------- Comment From segher.boessenkool.com 2018-09-18 12:38 EDT------- That fix may work, but it really isn't acceptable. Rotating the word (at any stage of the computation; 16 bit, 32 bit, or 64 bit) by one byte (or any odd number of bytes) will do. I think a patch for that was posted as well? Went in even, maybe? ------- Comment From segher.boessenkool.com 2018-09-18 13:10 EDT------- https://patchwork.ozlabs.org/patch/967868/ It was posted, but didn't go in yet. ------- Comment From hannsj_uhl.com 2018-09-24 11:17 EDT------- (In reply to comment #13) > https://patchwork.ozlabs.org/patch/967868/ > . ... which is upstream accepted in the powerpc tree as git commit https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git/commit/?h=fixes&id=85682a7e3b9c664995ad477520f917039afdc330 ("powerpc: fix csum_ipv6_magic() on little endian platforms") ... You can get a 4.19-rc kernel with the fix applied from https://copr.fedorainfracloud.org/coprs/sharkcz/talos-kernel/ and as I confirmed a moment ago, it helps :-) kernel-headers-4.18.10-200.fc28 kernel-tools-4.18.10-200.fc28 kernel-4.18.10-200.fc28 has been submitted as an update to Fedora 28. https://bodhi.fedoraproject.org/updates/FEDORA-2018-0edb45d9db kernel-4.18.10-300.fc29 kernel-headers-4.18.10-300.fc29 kernel-tools-4.18.10-300.fc29 has been submitted as an update to Fedora 29. https://bodhi.fedoraproject.org/updates/FEDORA-2018-5453baa4af kernel-headers-4.18.10-100.fc27 kernel-tools-4.18.10-100.fc27 kernel-4.18.10-100.fc27 has been submitted as an update to Fedora 27. https://bodhi.fedoraproject.org/updates/FEDORA-2018-c0a1284064 kernel-4.18.10-300.fc29, kernel-headers-4.18.10-300.fc29, kernel-tools-4.18.10-300.fc29 has been pushed to the Fedora 29 testing repository.
