Bug ID: 60437
Summary: SSL Handshake implementation in
AsycnChannelWrapperSecure does not handle
SSLEngineResult.Status.BUFFER_OVERFLOW state
Product: Tomcat 8
Version: 8.0.38
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: WebSocket
Assignee: dev@tomcat.apache.org
Reporter: dpa...@amdocs.com
Target Milestone: ----

sample program
This defect is related to an issue reported previously
(https://bz.apache.org/bugzilla/show_bug.cgi?id=54997) .
With the above fix, although BUFFER_UNDERFLOW is being handled, there is still
an issue with BUFFER_OVERFLOW.
Issue is reproduced by using WebSocketContainer to connect to a server which
requires clientcert authentication ( SSLEnabled="true" clientAuth="true" )
In this case, during the SSL handshake, when AsyncChannelWrapperSecure gets a
handshakeStatus of NEED_UNWRAP, it needs to dynamically resize the DUMMY
buffer, before invoking sslEngine.unwrap(socketReadBuffer, DUMMY), as
recommended by
http://docs.oracle.com/javase/7/docs/api/javax/net/ssl/SSLEngine.html .
The handshake fails with the following error :
javax.websocket.DeploymentException: The HTTP request to initiate the WebSocket
connection failed
