PROFILE
Ivan Morozko
Ivan Morozko developed core networking and data-plane features for the yanet-platform/yanet repository, focusing on high-throughput packet capture, real-time observability, and robust memory management. He engineered lock-free, slot-based ring buffers for tcpdump, introduced chunked memory allocation in dynamic hashtables, and refactored core tables using C++ with modern containers and shared memory. Ivan implemented CLI tools for PCAP streaming and export, enhanced automated testing with YAML-driven workflows, and improved code maintainability through modularization and formatting. His work addressed scalability, reliability, and testability, delivering a maintainable codebase that supports large-scale deployments and efficient debugging in C, C++, and shell scripting.

Jul 1, 2025July 2025 performance month focusing on delivering a high-throughput, reliable tcpdump data path, strengthening testing, and improving code quality in yanet. Key overhauls include a core architecture upgrade for tcpdump featuring a lock-free, slot-based ring buffer, exclusive follow-mode operation, and high-precision timestamping with TSC. The work was organized into dedicated ring-buffer modules to improve maintainability and performance, with removal of the outdated 'read' mode to reduce complexity. Major bug fixes addressed data integrity and logging reliability: fixed potential data corruption in shared memory ring buffers when producer lapped the reader by adding overflow detection and an automatic reader advancement to discard missed packets; redirected logging to appropriate error streams to prevent mixing with packet data and added a newline correction for YANET_LOG messages. Testing and quality improvements: expanded automated testing for tcpdump and pcap formats, including new autotest commands (shell_cli, comparePcaps), and tests for ring formats, overflows, and YAML integration; applied clang-format across the codebase to ensure consistent formatting. Overall impact: improved data integrity under high load, more reliable captures, faster validation cycles, and a stronger foundation for maintainability and future performance tunings. Technologies/skills demonstrated: C/C++ high-performance systems programming, lock-free data structures, shared memory IPC, high-resolution timestamping, performance optimizations, automated testing frameworks, shell scripting, YAML-driven test workflows, and code quality tooling (clang-format).

Dec 1, 2024Month: 2024-12 – Yanet platform 1) Key features delivered: - Core Dataplane Configuration and Memory Management Refactor: Reorganized dataplane configuration and memory management to boost modularity and performance. Extracted tDataPlaneConfig to a dedicated header, refactored shared memory allocation with unordered maps, introduced a static memory size calculator and NUMA helpers, replaced complex memory structures with a dedicated ShmInfo struct, and moved ShiftBuffer to the utils namespace for broader reuse. Commits: 47e4025dccbb3c97d93be3d6b0eb2cd60fa02fd6; 0a6f81882435c0ac8b0dd736849a6a0425da3efa; 8a9f9e4169c31d2ed1e1ae58182ee18871cb3cde; e5691283228c5ccb50b1fef7e3f69381b45276b5. - Dump Format Configuration for Packet Dump: Introduced a dump_format option to configure how packets are dumped into shared memory, supporting 'raw' and 'pcap' formats. Default behavior remains 'raw' when unspecified or invalid, laying groundwork for future pcap support. Commit: c1021fa4a3c41fb4b60c4f018dfa595cbfd699f7. - Autotest Stability and Build Simplification: Stabilized autotests by replacing fragile time-based checks with presence verification, disabled Link-Time Optimization (LTO) for autotest builds, and adjusted sleep timings to account for CI delays to ensure reliable test results. Commits: af3531a88a8c5b0ab140353686ab23d13cd9e200; 890fbcf71a955a4b916c40e51872b74d073bf882; 3feeadc2065215a0c7bf3a800caf1d5c059da340. 2) Major bugs fixed: - Autotest stability issues addressed by replacing flaky time-based checks with presence verification, reducing flakiness and CI churn (commits listed above). - Build/test reliability improvements via disabling LTO in autotest builds and adjusting sleep timings to accommodate CI delays. 3) Overall impact and accomplishments: - Improved dataplane modularity and memory management, enabling easier future enhancements and better performance characteristics in production workloads. - Established groundwork for PCAP-based packet dumps, enabling richer packet analysis capabilities with minimal behavioral changes for existing deployments. - Significantly improved CI reliability and reproducibility of autotests, reducing flaky results and speeding up feedback cycles for developers. 4) Technologies/skills demonstrated: - C++ refactoring and modular design: header extraction, namespace organization (utils), and memory subsystem restructuring with ShmInfo. - Advanced memory management: static size calculation, NUMA awareness, and efficient shared memory handling with unordered maps. - CI and build engineering: LTO considerations for autotest runs and CI timing adjustments. - Quality and reliability engineering: test stabilization and deterministic behavior in autotests.
