Jan 1, 2026January 2026 monthly summary for rackerlabs/genestack focused on documentation quality, network stability, and security hygiene. Delivered three primary outcomes: improved documentation for backup and Envoy Gateway setup; strengthened OVN networking by enabling FDB learning to prevent flooding when port security is disabled; strengthened Octavia security posture by moving temporary files to a user-specific directory in $HOME, reducing exposure of sensitive artifacts. These changes improve backup reliability and setup clarity, reduce network flooding incidents on provider networks, and lower risk of leaking SSH keys and artifacts. All work is tracked across the following commits for traceability: 0fd1e8e7ebd9e580086d1d68fc44915d1108ef43; 7ba5676684b6c3396e624220f33ad544062b1c35; 63fbb8061404a41fcac460f9a8996b0b911c660b; 7e1d0a5334cc4e78ae3e8030c75ed7e3a4cd9dfd.
