Berrify's approach could be extended to reduce the number of speculation barriers inserted for Spectre-STL defenses by implementing a more nuanced analysis of the BPF programs. Currently, Berrify inserts speculation barriers when the verifier detects unsafe behavior that could lead to transient execution attacks. To reduce the number of barriers for Spectre-STL, Berrify could incorporate additional checks to differentiate between critical stores that require barriers and safe operations that do not. By refining the analysis to only insert barriers when necessary, Berrify can minimize the impact on performance while still providing robust security against Spectre-STL vulnerabilities.
