Patch 1 just adds a performance test tool that is used throughout the series.
Patches 2+3 optimize the cases of non-found connections. This is a common case in combination with OVN for the reverse SNAT and reverse DNAT stages. The performance test tool is not covering this specific case. They where only tested on a real world setup. Patch 5-8 optimizes all modifying operations by splitting the locks for insert and deletions per zone. (In v3 this was a single patch) Patches 9-13 optimize connection cleaning. The goal is to have a predictable performance of the conntrack cleaning process independent if there is only a single gigantic zone in use or if there are a lot of small ones. The final patch adds a news entry for the changes. It also contains the performance improvements seen over the entire series. Felix Huettner (13): test-conntrack: Benchmark for conntrack on tcp. conntrack: Do not always take insert locks. conntrack: Use cmap for expectations. conntrack: Add more coverage values for conntrack. conntrack: Extract ct zone to separate struct. conntrack: Add per zone lock. conntrack: Move zone limits to per zone struct. conntrack: Remove exp_lists for connection cleaning. conntrack: Clean zones partially. cmap: Support switching between cursor and position. conntrack: Use cmap cursor for iteration. conntrack: Batch conn deletions in a single zone. conntrack: Immediately continue cleaning under load.
