PROFILE
Tomislav Novak
Worked on the bpftrace/bpftrace repository, delivering features and fixes that improved reliability, performance, and cross-platform compatibility for tracing tools. Addressed complex issues in C++ and LLVM IR, such as correcting tracepoint argument address calculations and enhancing error handling to prevent unintended aborts. Implemented new command line options for specifying traceable kernel functions, optimized startup performance, and expanded probe coverage across kprobes, uprobes, and watchpoints. Enhanced build system stability using CMake and Docker, resolving 32-bit and ARM compatibility issues. The work demonstrated depth in low-level Linux system programming, debugging, and build system management, supporting robust and flexible tracing workflows.

Mar 1, 2026March 2026 monthly summary for bpftrace/bpftrace: Delivered reliability, flexibility, and performance improvements across kprobes, uprobes, and watchpoints. Implemented address-based kprobes, resolved symbol-name conflicts with module-aware probing, relaxed ELF validation for unsafe mode, and added ZIP-archive probing support. Enhanced multi-thread probe coverage and startup performance for watchpoints by avoiding unnecessary symbol loading.
