PROFILE
Mauricio Vasquez
Mauricio Villacorta focused on enhancing the reliability of DNS tracing in the inspektor-gadget repository by addressing a critical bug in the DNS tracer’s per-CPU map handling. Working in C and leveraging expertise in network and system programming with eBPF, he corrected the use of the BPF_NOTEXIST flag and refined map_delete operations for percpu array maps. This targeted fix ensures that only necessary fields are cleared, reducing false negatives and state inconsistencies under concurrent workloads. Although no new features were released, Mauricio’s work improved production stability and laid a solid foundation for future DNS tracing enhancements in kernel-space observability.
