kernel securitysystem enhancementposition independent executableAntgroup Updates Linux: x86_64 PIE Support for Enhanced Security
Going back years there has been patches for allowing the Linux x86_64 kernel to build as Position Independent Executable (PIE) code to further enhance the system security. Antgroup engineers most recently have been tackling the Linux x86_64 PIE support and last week sent out a new patch series. . Based on the Linux PIE patches from a few years ago, Hou Wenlong with the Antgroup sent out updated patches for allowing Linux x86_64 PIE builds: "These patches make the changes necessary to build the kernel as Position Independent Executable (PIE) on x86_64. A PIE kernel can be relocated below the top 2G of the virtual address space. And this patchset provides an example to allow kernel image to be relocated in top 512G of the address space. The ultimate purpose for PIE kernel is to increase the security of the the kernel and also the [flexibility] of the kernel image's virtual address, which can be even in the low half of the address space. More locations the kernel can fit in, this means an attacker could guess harder. The patchset is based on Thomas Garnier's X86 PIE patchset v6 and v11. However, some design changes are made and some bugs are fixed by testing with different configurations and compilers." The link for this article located at Phoronix is no longer available. .

kernel securitysystem enhancementKASLREnhancing Kernel Security: KASLR Support for RISC-V Architecture
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. The link for this article located at Phoronix is no longer available. . KASLR boosts the security of the Linux kernel by introducing randomness in the address space layout, which helps in mitigating multiple types of attacks..
