Ash 3.0 Teasers unveil a range of improvements, emphasizing domain modeling, security, and developer experience. Key features include centralized action definitions, domain-specific policies, increased action safety through explicitness, and comprehensive documentation enhancements.
Main Points- Centralized action definitions through code interfacesAsh 3.0 introduces code interfaces on domain modules, centralizing action definitions and emphasizing domains in application structuring.
- Simplified security with domain-specific policiesDomain-specific policies in Ash 3.0 enable broad application of authorization logic, simplifying security management.
- Enhanced action safety and explicitnessThe new version prioritizes safety and explicitness in actions, making it necessary to explicitly declare attributes that an action accepts.
- Improved developer experience and documentationDeveloper experience improvements include enhanced autocomplete support and comprehensive documentation, particularly around code interfaces.

GhostRace is a comprehensive security analysis that identifies speculative execution vulnerabilities within common synchronization primitives in Linux and potentially other platforms. It reveals that Speculative Race Conditions (SRCs) can compromise architecturally race-free critical regions, enabling information leakage. The study proposes a mitigation strategy that balances security enhancement with minimal performance impact.
Main Points- Analysis of Speculative ExecutionA deep analysis on speculative execution reveals vulnerabilities in synchronization primitives across Linux and potentially other platforms
- Implications of SRCsSRCs (Speculative Race Conditions) enable information leakage, challenging the foundational security assumptions of critical regions in code
- Significance of GhostRace's FindingsA pioneering study, GhostRace uncovers serious flaws in current synchronization mechanisms, suggesting a reevaluation of security approaches
- Proposed Mitigation StrategyThe proposed mitigation, adding an lfence instruction post-lock comparison, balances security enhancement with minimal performance impact
