+Subject: [PATCH 1/2] session: Keep track of addr in fw_snat & session
+To: [email protected]
+Cc: [email protected]
+
+When there is more than one session in fw_snat's list of sessions,
+fw_snat failed to be re-created when update-session-state is triggered
+with new IP address. This is because index alone is not sufficient to
+decide if fw_snat needs to be re-created. The solution here is to keep
+a track of IP addr and use it to avoid false lookup of fw_snat.

+Subject: [PATCH] gweb: Fix a crash using wispr over TLS
+To: [email protected]
+Cc: [email protected]
+
+When gnutls_channel is instantiated, the gnutls_channel->established
+has to be initiated as FALSE. Otherwise, check_handshake function
+won't work. A random initial value 1 of gnutls_channel->established
+will make check_handshake return G_IO_STATUS_NORMAL, when the channel
+is actually not ready to be used. The observed behaviours are,
+
+- wispr is getting random errors in wispr_portal_web_result
+- ConnMan crashes on exit after those random errors
+- when wispr is luckly working, ConnMan doesn't crash on exit
