+Subject: [PATCH] web: Harden against invalid HTTP reason phrases
+
+We allow applications to set custom reason phrases for the HTTP status
+line (to support custom status codes), but if this were exposed to
+untrusted data it could be exploited in various ways. This commit
+guards against invalid reason phrases in both HTTP headers and in
+error pages.
