There is one thing you have to watch out for: certain vanilla kernel |
| 14 |
hardened features were subjugated to grsecurity ones and you'll probably |
| 15 |
want to enable them. For example, you probably want CONFIG_VMAP_STACK |
| 16 |
once you've switched, but it won't be enabled in your old .config |
| 17 |
because it conflicts with GRKERNSEC_KSTACKOVERFLOW. |
