Grsecurity has started development again. 1.9 has been deprecated. Reproducible: Always Steps to Reproduce: 1. 2. 3.
I don't maintain the grsec in gentoo-sources or gentoo-dev-sources. If anything in any of the gentoo-* kernels uses 1.9.x for anything then gradm will never work for them. Anyway kernel team here is the 2.x patch. http://grsecurity.net/grsecurity-2.0-2.4.26.patch You should just about be able to drop in replace this over the grsecurity-1.9.15-2.4.26
2.4.26-gentoo $ grep '#define GR_VERSION' 04-01.grsecurity.patch #define GR_VERSION "grsecurity 2.0"
