The Gentoo patches for the hardened kernel are largely cosmetic, |
| 8 |
changing configure-time portions to fit the Gentoo world-view. For |
| 9 |
the 2.6.29 kernel, they: |
| 10 |
|
| 11 |
- Remove 'grsec' from the kernel's version text |
| 12 |
- Reduce the compile-time warnings produced by grsecurity |
| 13 |
- Allow PaX to be enabled without enabling grsecurity |
| 14 |
- Set different (Gentoo-appropriate) default GIDs for the logging & |
| 15 |
restriction portions |
| 16 |
- Add Gentoo's profiles (server, workstation, etc.) for grsecuriity |
| 17 |
- Add the source IP to SELinux AVC messages (the only functional change) |
| 18 |
- Completely remove the ability to enable COMPAT_VDSO |
| 19 |

Gentoo's hardened-sources is probably the way you want to go, |
| 26 |
regardless. It incorporates the latest version of grsecurity for the |
| 27 |
given kernel version, and despite of being "behind" the kernel curve, |
| 28 |
it's highly stable. |
