LLVM Merges x86 LFI "Lightweight Fault Isolation" Target For In-Process Sandboxing
Stanford researchers have been developing Lightweight Fault Isolation "LFI" compiler passes and targets for LLVM as a means of efficient, native code sandboxing. The AArch64 LFI target was previously upstreamed while this week the x86/x86_64 LFI target was also upstreamed for this means of in-process sandboxing...
The upstreaming of the x86 LFI target follows the prior integration of AArch64 LFI, indicating a sustained effort by Stanford researchers and LLVM to enhance native code sandboxing capabilities.
This development enhances in-process sandboxing, crucial for improving the security and isolation of software components, particularly in complex systems and emerging compute paradigms.
LLVM now officially supports Lightweight Fault Isolation for x86/x86_64, providing a standardized and more efficient mechanism for in-process sandboxing across dominant architectures.
