https://github.com/copperhead/linux-hardened/wiki

It does seem to be derived from the now-defunct gentoo-hardened project. And from version numbers, it looks up to date. It doesnt seem to be in the portage tree.

The company behind it looks like theyre big into android (specifically nexus) security, but released sources to build for x64 too.

Anybody have any opinions or info to offer?

I do not know, if gentoo plans to incorporate copperhead-sources into portage.

Nonetheless you can use it. Make the directory
Code:
/etc/portage/patches/sys-kernel/vanilla-sources-4.14.9
and copy
Code:
 linux-hardened-4.14.9.a.patch
and
Code:
 linux-hardened-4.14.9.a.patch.sig
into this folder

Then install (or reinstall) vanilla-sources-4.14.9 which turns into copperhead-sources via the patch. (This approach does not work with gentoo-sources as its foundation)

Unfortunately copperhead-sources includes at the moment considerably less features then hardened-sources-4.9.x did (TPE, EMUTRUMP, ...). Additionally it is not clear what happens to the pax_kernel flag in future.

For the moment you can use the 4.9-lts series with grsec patches instead of copperhead (https://gpo.zugaina.org/sys-kernel/grsecurity-sources)

PS: Has anyone an idea what will happen to the "pax_kernel" flag in the near future.
