+Subject: [PATCH 1/3] WPS UPnP: Do not allow event subscriptions with URLs to
+ other networks
+
+The UPnP Device Architecture 2.0 specification errata ("UDA errata
+16-04-2020.docx") addresses a problem with notifications being allowed
+to go out to other domains by disallowing such cases. Do such filtering
+for the notification callback URLs to avoid undesired connections to
+external networks based on subscriptions that any device in the local
+network could request when WPS support for external registrars is
+enabled (the upnp_iface parameter in hostapd configuration).

+Subject: [PATCH 2/3] WPS UPnP: Fix event message generation using a long URL
+ path
+
+More than about 700 character URL ended up overflowing the wpabuf used
+for building the event notification and this resulted in the wpabuf
+buffer overflow checks terminating the hostapd process. Fix this by
+allocating the buffer to be large enough to contain the full URL path.
+However, since that around 700 character limit has been the practical
+limit for more than ten years, start explicitly enforcing that as the
+limit or the callback URLs since any longer ones had not worked before
+and there is no need to enable them now either.

+Subject: [PATCH 3/3] WPS UPnP: Handle HTTP initiation failures for events more
+ properly
+
+While it is appropriate to try to retransmit the event to another
+callback URL on a failure to initiate the HTTP client connection, there
+is no point in trying the exact same operation multiple times in a row.
+Replve the event_retry() calls with event_addr_failure() for these cases
+to avoid busy loops trying to repeat the same failing operation.
+
+These potential busy loops would go through eloop callbacks, so the
+process is not completely stuck on handling them, but unnecessary CPU
+would be used to process the continues retries that will keep failing
+for the same reason.
