Finer Grained KASLR Patches Revived For The Linux Kernel To Enhance Security
FG-KASLR continues to be designed around rearranging the kernel code at boot/load-time on a per-function level with minimal impact to the boot time.
Alexander Lobakin took the FG-KASLR work started by Intel's Kristen Accardi and has performed a "massive rework and a respin" of those patches. The new code now allows controlling the number of functions per section depending upon your kernel image size / protection level preference along with a variety of other improvements over the earlier versions of the patches. Plus there are various fixes and re-basing against the latest upstream Linux state.
Those interested in this FG-KASLR work can see this "v6" patch series for more details on this one of many efforts around beefing up Linux kernel security.
