Hi! |

I was asking about this before. But since then i made some progress: |
4 |
|
5 |
In the latest mm-sources there is the possibility to choose VIA C7 as |
6 |
processor. This is enabled by the x86_64-mm-add-an-option-for-the-via- |
7 |
c7-which-sets-appropriate-l1-cache.patch patch. I did not see the NX |
8 |
bit enabled message after booting (maybe there are too many messages? |
9 |
Is there a way to enlarge the kernel ring buffer?) but the second |
10 |
part of the test program mentioned in <http://www.ussg.iu.edu/ |
11 |
hypermail/linux/kernel/0612.1/0509.html> segfaults, so it seems to be |
12 |
working. |
13 |
|
14 |
After that i took the latest vanilla sources (the latest 2.6.20, |
15 |
since it was yesterday) and applied the mentioned patch. I got the |
16 |
same result, NX is working. |
17 |
|
18 |
After that i patched the hardened sources, but there the test is not |
19 |
working, no Segfault, no Nx bit. I disabled PAX_NOEXEC, still the |
20 |
same results. |
21 |
|
22 |
Is there anything obvious i missed, something i could try? |
23 |
|
24 |
Thanks, |
