Please see details in URL. At least, current stable versions of both hardened and non-hardened kernels in Gentoo are uncapable to serve gre tunnels. I hope this would be merged in next kernel releases...
My guess is that the fix will be in 3.14.15 and 3.15.8. Given the speed of kernels, this won't be long. If it is, we can backport it into gentoo-sources, but I doubt we need to.

I have strange results: two servers, one - amd64, one - x86 3.14.16 fixes issue for amd64 one, but not for x86 one. Need to dig deeper, the only one difference is enabled CONFIG_NET_IPGRE_BROADCAST=y on x86, maybe this is another issue, i will check...

Checked again, CONFIG_NET_IPGRE_BROADCAST is unrelevant, GRE tunnels still broken on x86 and 3.14.16
is this still an issue with the latest 3.14 kernel which is 3.14.21 as of this writing?
