+Subject: [PATCH] FTP: when EPSV gets a 229 but fails to connect, retry with PASV
+
+This is a regression as this logic used to work. It isn't clear when it
+broke, but I'm assuming in 7.28.0 when we went all-multi internally.
+
+This likely never worked with the multi interface. As the failed
+connection is detected once the multi state has reached DO_MORE, the
+Curl_do_more() function was now expanded somewhat so that the
+ftp_do_more() function can request to go "back" to the previous state
+when it makes another attempt - using PASV.
+
+Added test case 1233 to verify this fix. It has the little issue that it
+assumes no service is listening/accepting connections on port 1...
+
+Reported-by: byte_bucket in the #curl IRC channel
+
+[upstream commit 7cc00d9a832c42a330888aa5c11a2abad1bd5ac0]
