+Subject: [PATCH] http2: cap originSet size to prevent unbounded memory
+growth
+
+A malicious HTTP/2 server can send repeated ORIGIN frames with unique
+origins, causing unbounded growth of the client-side originSet for the
+lifetime of the session. Cap the set at 128 entries; once full, new
+origins from ORIGIN frames are silently dropped.
