Ard Biesheuvel 6f26b36711 arm64: kaslr: increase randomization granularity ... Currently, our KASLR implementation randomizes the placement of the core kernel at 2 MB granularity. This is based on the arm64 kernel boot protocol, which mandates that the kernel is loaded TEXT_OFFSET bytes above a 2 MB aligned base address. This requirement is a result of the fact that the block size used by the early mapping code may be 2 MB at the most (for a 4 KB granule kernel) But we can do better than that: since a KASLR kernel needs to be relocated in any case, we can tolerate a physical misalignment as long as the virtual misalignment relative to this 2 MB block size is equal in size, and code to deal with this is already in place. Since we align the kernel segments to 64 KB, let's randomize the physical offset at 64 KB granularity as well (unless CONFIG_DEBUG_ALIGN_RODATA is enabled). This way, the page table and TLB footprint is not affected. The higher granularity allows for 5 bits of additional entropy to be used.
