Summary
This patch fixes a bug related to RTDS runtime guard overrides and introduces new opt-in features for monitoring HTTP/2 header statistics and limiting cookie header size.
Migration Steps
- If using the new HTTP/2 histograms feature, be aware that the histograms and the associated runtime guard will be removed in a future Envoy release.
✨ New Features
- Added opt-in histograms for HTTP/2 header statistics (header-entry count, header-map byte size, reassembled cookie header length, and individual cookie header count). Enable via the runtime feature flag envoy.reloadable_features.http2_record_histograms.
- Added runtime feature envoy.reloadable_features.http2_max_cookies_size_in_kb to limit the size of the reassembled HTTP/2 cookie header (default is no limit).
🐛 Bug Fixes
- Fixed an issue where deleting an RTDS runtime guard override did not correctly restore the process-wide runtime guard value to its default.
