FSBG update version 1.0.930 has been released. FSBG is a component of Linux Security 64. This release includes the following changes:
- Improved on-access scanning behavior under high system load. Previously, bursts of rapid file access could overwhelm the scanning subsystem and lead to file access failures. The updated behavior applies controlled backpressure—intentionally slowing certain filesystem operations when overload is detected—to prevent scanning saturation and maintain reliable file access.
- Reduced the rate at which available-memory telemetry is reported to the backend. The previous reporting cadence generated unnecessary traffic with limited operational benefit.
- The scanning service now runs under a non-privileged user account and incorporates additional hardening and sandboxing measures to further improve security.
- On-access scanning now skips the special
tracefs filesystem, which has never been compatible with scanning. - Update log entries now consistently use UTC timestamps.
