Hi! I'd like to get this one up by Saturday so that we can proceed with masking and removing of the hardened-sources after upstream stopped releasing new patches.
This is my first time writting a news item so all input will be appreciated. As for the rationale behind this, we need to clearly inform users as to the options available for hardening their system kernels after the removal of the hardened-sources. Sincerely, Klondike
Title: sys-kernel/hardened-sources removal Author: Francisco Blas Izquierdo Riera (klondike) <klond...@gentoo.org> Posted: 2017-08-19 Revision: 1 News-Item-Format: 2.0 Display-If-Installed: sys-kernel/hardened-sources As you may know the core of sys-kernel/hardened-sources have been the patches published by Grsec. Sadly, their developers have stopped making these freely available [1]. 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 then 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 Grsec user, is forward porting the patches on [2]. The Gentoo Hardened team can't make any statement regarding the security, reliability or update availability of 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. Finally we'd like to send a sincere thank you to Brad Spengler and the PaX Team for making their hardening patches freely available all this time.
