Description Sergey Popov (RETIRED) gentoo-dev

In short - build failure caused my missing function ip_tunnel_get_stats64

See URL for discussion about how to fix this properly

After applying patch, everything builds fine

Is this a problem in the latest hardened-sources?

Well, it's not hardened issue itself.

As you can see, issue presents in some vanilla kernels too, i can not say in which versions.

hardened-sources-3.14.5 has ip_tunnel_get_stats64 in right place(in net/ipv4/ip_tunnel_core.c)

hardened-sources-3.13.10 has this function in net/ipv4/ip_tunnel.c, which is wrong.

@kernel team.  Is this a known issue in vanilla?

The 3.13 kernel branch is EOL and this is in 3.15.1. Is there somewhere else you want to see this patch?

Did not check other kernels. But if 3.13.10 will remain in STABLE as is now(e.g. broken), it's not good. Either fix it or drop it, please - your choice, as maintainer.

Latest stable(3.14.5-r2) builds fine(as patch was merged upstream)

3.13 no longer in tree
