# Thesis notes
|
|
## TU Graz Paper
|
|
- Enable strict memory permissions or virtualize kernel heap or kernel stack
|
|
- kernel allocator massaging (?)
|
|
- These defenses change mapping to fine-grained 4kB instead of 2MB
|
|
- 4kB TLB entries result in contention patterns observable via side channels
|
|
- leak page aligned object locations
|
|
- deduce sup-page granular objects (how?)
|
|
- intel CPU needed (8th-14th gen) (?)
|
|
|
|
## FD limit
|
|
- Must increase number of allowed FDs for spray to work. E.g. with `ulimit -n $(ulimit -n -H)`
