Trustin Lee updated DIRMINA-123:
--------------------------------
Version: (was: 0.9)
> Race condition in AbstractIoFilterChain
> ---------------------------------------
>
> Key: DIRMINA-123
> URL: http://issues.apache.org/jira/browse/DIRMINA-123
> Project: Directory MINA
> Type: Bug
> Reporter: Vinod Panicker
> Assignee: Trustin Lee
> Fix For: 0.9
>
> There is a race condition that occurs due to filter handling in AbstractIoFilterChain. The bug manifested itself when using the client side of the SSLFilter impl. In the register method below -
> private void register( Entry prevEntry, String name, IoFilter filter ) throws Exception
> {
> Entry newEntry = new Entry( prevEntry, prevEntry.nextEntry, name, filter );
> filter.init( this, newEntry.nextFilter );
>
> prevEntry.nextEntry.prevEntry = newEntry;
> prevEntry.nextEntry = newEntry;
> name2entry.put( name, newEntry );
> filter2entry.put( filter, newEntry );
> }
> filter.init causes the ssl client HELLO to be sent to the server. If the client and server are on a fast network, the server response comes before the filter has been "put", causing it to be handed to the IoHandler.
> Solution is to init the filter after putting it on the session.
