Chirantan worked on performance-focused kernel security optimization for the KernelSU repository, implementing a caching layer for SELinux Security Identifier (SID) lookups targeting the su, zygote, and init domains. Using C programming and kernel development expertise, Chirantan replaced repeated string-based SID resolutions with efficient integer comparisons, reducing overhead during security context checks. The solution introduced an init-time caching mechanism, enabling faster and more scalable security policy evaluation under both normal and peak loads. This work demonstrated a solid understanding of security architecture and laid the groundwork for broader policy evaluation improvements, reflecting depth in both technical approach and implementation.
