Use the same maximum frame length for all transports.

Don't try to erase secrets from memory.
...
1. The things we're really trying to protect - contact identities,
message contents, etc - can't be erased from memory because they're
encapsulated inside objects we don't control.
2. Long-term secrets can't be protected by erasing them from memory
because they're stored in the database and the database key has to be
held in memory whenever the app's running.
3. If the runtime uses a compacting garbage collector then we have no
way to ensure an object is erased from memory.
4. Trying to erase secrets from memory makes the code more complex.
Conclusion: Let's not try to protect secrets from an attacker who can
read arbitrary memory locations.

Improved encapsulation of thread synchronisation as follows
...
- replaced use of Object instance mutex with a private final Lock object
- replaced Object signaling with specific condition signalling

Check periodically for retransmittable packets. Bug #46 .
2014-12-14 20:26:41 +00:00
29a6596ee3
Use the transport's idle timeout, not a hardcoded value.

Application layer keepalives to detect dead TCP connections.
...
DuplexOutgoingSession flushes its output stream if it's idle for a
transport-defined interval, causing an empty frame to be sent. The TCP
and Tor plugins use a socket timeout equal to twice the idle interval to
detect dead connections.
See bugs #27 , #46 and #60 .

Updated Bouncy Castle source code.
2014-12-04 12:06:41 +00:00

Added Gradle build files because Ant's too efficient for some people.
2014-11-25 14:54:34 +00:00
ab467b3d3e
Flush the output stream before rather than after waiting for packets.
...
See bug #27 .
2014-11-09 18:03:24 +00:00

Added missing packet handlers to IncomingSession.

Refactored PluginManager and Poller to remove non-open calls. Bug #15 .

Some variables were still referring to TagRecogniser by its old name.
2014-11-06 20:51:10 +00:00

Renamed some inner classes to match the renamed outer class.

Messaging sessions aren't responsible for closing their streams.
...
The TransportReader/Writer's dispose() method should handle that, and
ConnectionManager is responsible for calling it.
2014-11-06 13:13:23 +00:00
b27a17db88
Erase temporary secrets after deriving keys.
2014-11-06 08:39:07 +00:00
1f4d801162
Interrupt all messaging sessions when the app starts shutting down.
...
This makes it more likely that connections will be closed cleanly.
However, the interrupt() method is currently ineffective for incoming
sessions as it won't interrupt a blocking read, e.g. when the packet
reader is waiting for a packet.
2014-11-06 08:24:08 +00:00
852a618cb3
Interrupt messaging session if contact or transport is removed.
2014-11-06 08:10:29 +00:00
c202b6f0ac
Renamed ConnectionManager to ConnectionDispatcher.
...
Because that's what it does.
2014-11-05 19:47:54 +00:00
4ca83842d1
Moved ConnectionDispatcher and ConnectionRegistry to plugins package.
2014-11-05 19:40:07 +00:00
26d93b83b4
Factored out StreamReader/Writer from messaging layer.
2014-11-05 19:22:01 +00:00

Cancel database queries if the messaging session has been interrupted.
2014-11-05 18:34:59 +00:00

Interrupt the other side of a duplex connection if an exception occurs.

PacketWriters aren't responsible for flushing their output streams.

Massive refactoring to merge handling of simplex and duplex connections.
2014-11-04 16:51:25 +00:00
b24f153704
Renamed a load of things from 'connection' to 'stream'.

Combine the system's PRNG with Fortuna, in case either one is flawed.
2014-10-08 15:03:19 +01:00
bb38911dc8
SecureRandom impl that XORs the outputs of other impls (not yet used).
...
This can be used to combine e.g. the platform's SecureRandom
implementation with our own, so that a weakness in either source doesn't
harm security as long as the other source is strong.
2014-10-08 15:03:02 +01:00
4e028e217b
Upgraded BouncyCastle to 1.51.

Merged ReliabilityExecutor into IoExecutor.
2014-10-02 18:06:05 +01:00
941efb4bbe
Merged IncomingConnectionExecutor and PluginExecutor into IoExecutor.
...
We don't need two separate executors for long-running IO threads.
2014-10-02 18:02:53 +01:00
458c0ca285
Don't broadcast MessageAddedEvent if message wasn't added.
...
Fixed a bug in SimplexMessagingIntegrationTest that should've caught
this.
2014-07-04 15:16:56 +01:00
96a9178b0b
Use a single read-write lock for the DB - don't optimise prematurely.
2014-07-04 15:16:56 +01:00
f90f7c5e7b
Use a single-threaded executor for the database.
...
This ensures that if two DatabaseExecutor tasks update the database and
broadcast events, the events are broadcast in the same order as the
updates occurred.
2014-07-04 15:16:55 +01:00
4c9296d286
Merged all licensing info into a single file to avoid APK build problems.

eaff042601
Don't try to close server sockets twice.
...
This may have been the cause of bug #69 . Removed the wait-for-shutdown
code in DroidtoothPlugin that was added to attempt to avoid that bug.
