SSL handshake in AsyncChannelWrapperSecure fails with the
"javax.net.ssl.SSLException: TODO" error.
Its failing because of BUFFER_OVERFLOW during handshake.
Caused by: javax.net.ssl.SSLException: TLS handshake returned an unexpected
status [BUFFER_OVERFLOW]
at
org.apache.tomcat.websocket.AsyncChannelWrapperSecure$WebSocketSslHandshakeThread.checkResult(AsyncChannelWrapperSecure.java:430)
Seems like tomcat is not handling dynamic buffer resizing for BUFFER_OVERFLOW
as recommended in
http://docs.oracle.com/javase/7/docs/api/javax/net/ssl/SSLEngine.html. Its
handled and fixed for BUFFER_UNDERFLOW.
Temporarily, we increased buffer size of the temporary buffer to 64kb in
/org/apache/tomcat/websocket/AsyncChannelWrapperSecure.java and now we are able
to have successful handshake. Originally it was 8192 bytes.
We have raised issue (https://bz.apache.org/bugzilla/show_bug.cgi?id=60437) to
handle BUFFER_OVERFLOW, and attached a sample client that can be used to
reproduce the issue.
Thanks,
