True — this is made necessary by having to support virtualized |
| 6 |
environments (and, of course, Xorg, wrt. GRKERNSEC_IO). Since out last |
| 7 |
discussion on the subject, I have “discovered” the |
| 8 |
GRKERNSEC_HARDENED_VIRTUALIZATION profile, which fits quite well the |
| 9 |
settings that were carefully selected previously. |

By the way, Liberté also mounts /dev with noexec, and I received no |
| 12 |
complaints so far (see bug #92921). I also grepped the driver sources |
| 13 |
before making the change, and didn't find any attempts to map /dev/mem |
| 14 |
with PROT_EXEC. No idea if the noexec issue is still present with |
| 15 |
proprietary drivers, though. |
