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)
