Re-think of RichACLs in AI/LLM Era

Explore the renewed relevance of Rich Access Control Lists (RichACLs) in modern AI and Large Language Model applications through this Linux Plumbers Conference presentation. Learn how a startup providing AI/LLM capabilities for personal and micro-enterprise storage has encountered complex access control challenges that traditional POSIX ACLs cannot adequately address. Discover the specific use cases where different users and roles store sensitive data in shared storage pools while requiring sophisticated access controls for AI processing tasks. Examine the scalability and performance limitations of user-space access control solutions, particularly when handling large numbers of files and hot datasets. Understand how RichACLs could provide context-aware and efficient file system-level access control when combined with high-level policy agents for task and session-oriented management. Gain insights into the technical barriers and remaining development work needed to integrate RichACLs into the upstream Linux kernel, supported by real-world deployment data from over one million active installations running AI workloads daily.
