April 2025 (fluent/fluent-bit): Strengthened stability and reliability by fixing a memory-safety issue in the Input Chunk Mapping for routes_mask. Implemented allocation with flb_calloc and ensured cleanup on error to prevent crashes or leaks when allocation or validation fails, addressing a critical edge-case in input routing. This work reduces downtime risk in production ingest pipelines and improves long-term maintainability by preventing leaks and unstable behavior in input processing. Commit referenced: 795032eccf888b4d4ab46760459eb642da55bde5 (input_chunk: routes_mask is not initialized (#10223)).
