| | | | | | Various errors exposed when connecting to RealVNC servers on alternative platforms (ARM, SPARC). SSLEngineManager was also cleaned up but most of the changes are cosmetic.

* Fix getSockPort methods in java TcpSocketBrian P. Hinz2014-11-132-6/+5
| | | | | | | Although not actually used anywhere, the getSockPort method was actually returning the the remote socket's port number. Also simplified some of the other socket methods.
* Make sure sockets are shutdown in java viewer listen modeBrian P. Hinz2014-11-132-6/+15
| | | | | | The finalizer method may not be strictly necessary but for the sake of consistency shutdown the socket listener the same way we do for a regular TcpSocket.

* More enhancements to java SSLEngineManagerBrian P. Hinz2014-11-041-44/+44
| | | | | | | | | | * Blocking behavior in the read() method was leading to high CPU usage. * GC wasn't purging temporary byte arrays used to transfer data between I/O streams and NIO byte buffers, causing excessive memory usage. * Some optimization of read() behavior to reduce the frequency of blocking operations.
* Major overhaul of SSLEngineManagerBrian P. Hinz2014-11-021-167/+124
| | | | | | | | | | | | | | | | | | | | | | | | The SSLEngineManager was basically an abomination. The work is now done as it should be, with the buffers being fed and the engine deciding when data is consumed or produced. The engine should be much more robust now as well. Additionally, although JRE 7 supports the TLSv1.1 and TLSv1.2 protocols, they are not actually enabled by default. The JSSE reference cites compatibility reasons for this but this doesn't appear to be the case with the TigerVNC server and they will be enabled by default in JRE 8. The regular expression for enabling anonymous DH cipher suites was too narrow and excluded the elliptic curve ciphers, which are now ordered ahead of the ephemeral ciphers by the default security provider. Lastly, increase the size of the buffer in FdOutStream from 8Kb to 16Kb. I'm not sure why FdInStream and FdOutStream were asymmetric to begin with, but 16Kb is the default size for TLS packets and there seems to be now negative effects on plain text connections.

Since our SSLEngineManager class was loosely inspired by, but no code was actually borrowed from, the Oracle JSSE examples, it is my opinion that it was incorrect to attribute copyright to Oracle, so that message has been removed (their examples are released under a BSD-style license, anyhow, so it's a non-issue.) git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4962 3789f03b-4d11-0410-bbf8-ca57d06f2519

Still a fair amount of cleanup to do, particularly in the SSL handler, which is not very robust, and exception handling in general. All core functionality appears to be working fine though. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4842 3789f03b-4d11-0410-bbf8-ca57d06f2519
