Worked on integrating the upstream OSS-Fuzz fuzz testing backend for BIND 9 within the google/oss-fuzz repository, replacing the previous local backend to streamline and modernize the fuzzing workflow. The approach involved updating build scripts and configuration to pass the fuzzing engine through meson-based builds using C and Shell scripting, while removing an obsolete patch to reduce maintenance overhead. Build and link optimizations were implemented, such as resolving symbol linkage and eliminating duplicate fuzzing entry points. This work enhanced maintainability and ensured that the fuzzing process leveraged upstream improvements, focusing on build automation and robust fuzz testing practices.
