2014-05-14	Minor stylistic fixes, no functional changes.	Yawning Angel

2014-05-13	Add vim modelines to some files (No functional changes).	Yawning Angel

2014-05-13	Fix up import.	Yawning Angel

2014-05-13	Fix copyLoop to break out the other goroutine on graceful exit.	Yawning Angel
	This should fix sockets getting stuck in CLOSE_WAIT.
2014-05-13	Fix e-mail address in the copyright notice.	Yawning Angel

2014-05-13	Add preliminary support for packet length obfuscation.	Yawning Angel
	The same algorithm as ScrambleSuit is used, except: * SipHash-2-4 in OFB mode is used to create the distribution. * The system CSPRNG is used when sampling the distribution. This fixes most of #3, all that remains is generating and sending a persistent distribution on the server side to the client.
2014-05-12	Fix logging again.	Yawning Angel
	On second thought instead of using log.Panicf(), panic() and do the logging with recover(). This somewhat centralizes logging in obfs4proxy, which will be easier to change when I invariably decide to do logging differently in the future.
2014-05-12	Log and propagate errors between the 2 goroutines in copyLoop.	Yawning Angel
	This fixes #1.
2014-05-12	Fix a comment (No functional changes).	Yawning Angel

2014-05-12	Preliminary support padding, log on panic.	Yawning Angel
	This adds preliminary support for data padding by adding another layer of encapsulation inside each AEAD frame containing a type and length. For now, data is still sent unpadded, but the infrastructure for supporting it is mostly there. Additionally, use log.Panic[f]() instead of panic through out the code so that some panics are logged.
2014-05-12	Remove support for Write deadlines since it wasn't working.	Yawning Angel
	Write timeouts are obnoxious to handle as the frame encoder state already is updated to cover the entire payload for the Write() call that timed out. In theory it is possible to buffer the pending data, but that causes Write() to voilate the semantics of the interface.
2014-05-12	Set a timeout on outgoing handshakes as well.	Yawning Angel

2014-05-12	Reject clients that do not authenticate quickly enough.	Yawning Angel
	The current timeout value before the server fails the handshake is 15 s. This may need to be increased for clients over slow links.
2014-05-12	Close connections that fail to authenticate after a while.	Yawning Angel
	Like ScrambleSuit, a random interval between 1x and 5x of additional data from the peer is read and immediately discarded before closing. Additionally, obfs4 will close off invalid connections anywhere between 0 and 60 seconds after it determines that the incoming connection will never complete the handshake successfully.
2014-05-12	Clean up the logging a bit.	Yawning Angel

2014-05-12	Run go fmt on obfs4proxy.go (No functional changes).	Yawning Angel

2014-05-12	Move to a unified client/server binary, and fix bugs.	Yawning Angel
	* The old and the busted: obfs4-[client,server]. * The new hotness: obfs4client. * Add obfs4.ServerHandshake() that servers need to call after a successful return from Accept(). This allows implementations to move the handshake into a goroutine or whatever.
2014-05-11	Change documentation/comments to reflect reality (No functional changes).	Yawning Angel

2014-05-09	Remove a comment that I forgot to delete, no functional changes.	Yawning Angel

2014-05-09	Initial import.	Yawning Angel
