At this point, the only feature that I'm aware of which we have in the Ubuntu kernel and hasn't been merged upstream yet is support for overlayfs inside user namespaces. The other big one for a long time was fuse inside user namespaces, but that has been merged upstream in 4.18. Some of the AppArmor features were also a sticky point for a while as upstream was lagging behind quite a bit, but the AppArmor maintainer has since fixed that, so recent Linux kernels have everything that we use. |
