Worked on the derailed/cilium repository to address stale proxymap cleanup within BPF maps, focusing on improving proxy map lifecycle management. The approach involved unconditionally removing old proxymaps, which reduced the risk of stale entries and stabilized proxy behavior. Expanded the initial cleanup process to include both cilium_proxy4 and cilium_proxy6, ensuring broader coverage of potential stale map issues. Updated documentation to clearly reflect the new cleanup behavior and its impact on system reliability. Utilized Go for development and RST for documentation, applying system programming and BPF expertise to deliver a targeted bug fix that enhanced overall system robustness.
