Nowadays it is, but this hasn't always been the case. You'll notice the presence of a /dev/grsec and you'll also find grsec referenced accross some old patches. Anyways I changed it. The same applies to Open Source Security, Inc. the company was founded on 2008 but grsecurity has been around for much longer. That's why I prefer to refer to Brad Spengler and The PaX team here as they are still the real upstream behind Open Source Security, Inc.
Title: sys-kernel/hardened-sources removal Author: Francisco Blas Izquierdo Riera <klond...@gentoo.org> Posted: 2017-08-19 Revision: 4 News-Item-Format: 2.0 Display-If-Installed: sys-kernel/hardened-sources Display-If-Profile: hardened/linux/* As you may know the core of sys-kernel/hardened-sources have been the grsecuirty patches. Sadly, their developers have stopped making these patches freely available [1]. This is a full stop of any public updates and not only stable ones as was announced two years ago[2]. As a result, the Gentoo Hardened team is unable to keep providing further updates of the patches, and although the hardened-sources have proved (when using a hardened toolchain) being resistant against certain attacks like the stack guard page jump techniques proposed by Stack Clash, we can't ensure a regular patching schedule and therefore, the security of the users of these kernel sources. Because of that we will be masking the hardened-sources on the 27th of August and will proceed to remove them from the tree by the end of September. Obviously, we will reinstate the package again if the developers decide to make their patches publicly available again. Our recommendation is that users should consider using instead sys-kernel/gentoo-sources. As an alternative, for users happy keeping themselves on the stable 4.9 branch of the kernel; minipli, another grsecurity user, is forward porting the patches on [3]. Strcat from Copperhead OS is making his own version of the patches forward ported to the latest version of the Linux tree at [4]. The Gentoo Hardened team can't make any statement regarding the security, reliability or update availability of either those patches as we aren't providing them and can't therefore make any recommendation regarding their use. We'd like to note that all the userspace hardening and MAC support for SELinux provided by Gentoo Hardened will still remain there and is unaffected by this removal. Also, all PaX related packages other than the hardened-sources will remain for the time being.
