2014-05-15 | Make the output from "-gen" be more useful. | Yawning Angel | |
2014-05-15 | Use os.MkdirAll() for creating the pt state directory. | Yawning Angel | |
2014-05-15 | Fix up how Read() errors were processed where appropriate. | Yawning Angel | |
2014-05-14 | Changed the taglne to "The obfourscator", per dcf's suggestion. | Yawning Angel | |
2014-05-14 | Remove a newline to make godoc work (No functional changes). | Yawning Angel | |
2014-05-14 | Change the framing Encoder/Decoder to take the destination slice. | Yawning Angel | |
In theory this is easier on the garbage collector. Probably could reuse more of the intermediary buffers by stashing them in the connection state, but that makes the code kind of messy. This should be an improvement. | |||
2014-05-14 | Fix comment (No functional changes). | Yawning Angel | |
2014-05-14 | Update README (No functional changes). | Yawning Angel | |
2014-05-14 | Kill Obfs4Conn.isOk with fire, and replace it with a state var. | Yawning Angel | |
2014-05-14 | First pass at cleaning up the write code. | Yawning Angel | |
2014-05-14 | Implement the io.WriterTo interface. | Yawning Angel | |
2014-05-14 | First pass at cleaning up the read code. | 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 | |
