Subject [jira] [Commented] (HTTPCORE-319) SSLIOSession goes into a loop if the server rejects an invalid certificate
Date Thu, 29 Nov 2012 22:50:58 GMT

    [ https://issues.apache.org/jira/browse/HTTPCORE-319?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13506903#comment-13506903
] 

Scott Stanton commented on HTTPCORE-319:
----------------------------------------

1) The loop I was seeing was that the socket is readable because of an EOF, SSLIOSession.isAppInputReady
is called and detects bytesRead is -1, setting endOfStrream to true.  It then continues on
to doHandshake, etc and returns to the reactor, leaving the read mask set.  Since the socket
is still at EOF, the reactor immediately starts the whole process over again.
2) I still don't have a reliable way to reproduce the problem (it only happens a couple of
times each day), but I'll try the patch and see if it helps.

> To reproduce:
> * Set up an SSL server that requests certificates from the client.
> * Set up a client with an expired SSL certificate.
> * Establish a connection from the client to the server using BaseNIOReactor and SSLIOSession.
> The server will proceed through the handshake until the client supplies its certificate
in response to the CertificateRequest message.  At this point, the server's certificate verification
will fail and it will close the connection. 
> The client socket will become readable due to the EOF and the SSLIOSession.isAppInputReady()
method is called to handle the EOF.  The bytesRead gets set to -1, which sets this.endOfStream
= true.  Nothing ever sets the session into the CLOSING or CLOSED state, so it keeps looping
on the readable EOF event.
> I'm not sure what the best approach to fixing this should be.  It appears that if I close
the session manually with the debugger from inside isAppInputReady, the system proceeds normally
from that point, however I don't know what the implications of doing that might be.
