While there has been much work on the Linux kernel's RISC-V CPU architecture support, a feature not tackled until now has been the Kernel Address Space Layout Randomization (KASLR) support for randomizing the kernel mapping to enhance system security.

KASLR allows for address space randomization of the running Linux kernel. This is a beneficial security enhancement especially when challenged by other attacks that can potentially leak kernel addresses and then defeating further exploits that rely upon known offsets/locations from within kernel memory. More broadly there has also been FGKASLR for finer-grained KASLR that can randomize address space randomization down to the function level but sadly that work seems to still be stalled for the past year.

Sent out on Wednesday were four kernel patches for wiring up KASLR support for the RISC-V architecture.
