* 2005-07-27 0.6 released
2005-07-27 jrandom
* Enabled SSU as the default top priority transport, adjusting the
config.jsp page accordingly.
* Add verification fields to the SSU and TCP connection negotiation (not
compatible with previous builds)
* Enable the backwards incompatible tunnel crypto change as documented in
tunnel-alt.html (have each hop encrypt the received IV before using it,
then encrypt it again before sending it on)
* Disable the I2CP encryption, leaving in place the end to end garlic
encryption (another backwards incompatible change)
* Adjust the protocol versions on the TCP and SSU transports so that they
won't talk to older routers.
* Fix up the config stats handling again
* Fix a rare off-by-one in the SSU fragmentation
* Reduce some unnecessary netDb resending by inluding the peers queried
successfully in the store redundancy count.
2005-07-22 jrandom
* Use the small thread pool for I2PTunnelHTTPServer (already used for
I2PTunnelServer)
* Minor memory churn reduction in I2CP
* Small stats update
2005-07-21 jrandom
* Fix in the SDK for a bug which would manifest itself as misrouted
streaming packets when a destination has many concurrent streaming
connections (thanks duck!)
* No more "Graceful shutdown in -18140121441141s"
2005-07-20 jrandom
* Allow the user to specify an external port # for SSU even if the external
host isn't specified (thanks duck!)
2005-07-19 jrandom
* Further preparation for removing I2CP crypto
* Added some validation to the DH key agreement (thanks $anon)
* Validate tunnel data message expirations (though not really a problem,
since tunnels expire)
* Minor PRNG threading cleanup
* Added workaround for an odd win32 bug in the stats configuration console
page which meant only the first checkbox selection was saved.
* Added per group selection toggles in the stats configuration console
page.
2005-07-13 jrandom
* Fixed a recently injected bug in the multitransport bidding which had
allowed an essentially arbitrary choice of transports, rather than the
properly ordered choice.
2005-07-13 jrandom
* Fixed a long standing bug where we weren't properly comparing session
tags but instead largely depending upon comparing their hashCode,
causing intermittent decryption errors.
* Add some data duplication to avoid a recently injected concurrency
problem in the session tag manager (thanks redzara and romster).
2005-07-11 jrandom
* Reduced the growth factor on the slow start and congestion avoidance for
the streaming lib.
* Adjusted some of the I2PTunnelServer threading to use a small pool of
handlers, rather than launching off new threads which then immediately
launch off an I2PTunnelRunner instance (which launches 3 more threads..)
* Don't persist session keys / session tags (not worth it, for now)
* Added some detection and handling code for duplicate session tags being
delivered (root cause still not addressed)
* Make the PRNG's buffer size configurable (via the config property
"i2p.prng.totalBufferSizeKB=4096")
* Disable SSU flooding by default (duh)
* Updates to the StreamSink apps for better throttling tests.
2005-07-05 jrandom
* Use a buffered PRNG, pulling the PRNG data off a larger precalculated
buffer, rather than the underlying PRNG's (likely small) one, which in
turn reduces the frequency of recalcing.
* More tuning to reduce temporary allocation churn
2005-07-04 jrandom
* Within the tunnel, use xor(IV, msg[0:16]) as the flag to detect dups,
rather than the IV by itself, preventing an attack that would let
colluding internal adversaries tag a message to determine that they are
in the same tunnel. Thanks dvorak for the catch!
* Drop long inactive profiles on startup and shutdown
* /configstats.jsp: web interface to pick what stats to log
* Deliver more session tags to account for wider window sizes
* Cache some intermediate values in our HMACSHA256 and BC's HMAC
* Track the client send rate (stream.sendBps and client.sendBpsRaw)
* UrlLauncher: adjust the browser selection order
* I2PAppContext: hooks for dummy HMACSHA256 and a weak PRNG
* StreamSinkClient: add support for sending an unlimited amount of data
* Migrate the tests out of the default build jars
2005-06-22 Comwiz
* Migrate the core tests to junit
2005-05-01 jrandom
* Added a substantial optimization to the AES engine by caching the
prepared session keys (duh).
2005-05-01 jrandom
* Cleaned up the peers page a bit more.
2005-04-30 jrandom
* Added a small new page to the web console (/peers.jsp) which contains
the peer connection information. This will be cleaned up a lot more
before 0.6 is out, but its a start.
2005-04-30 jrandom
* Reduced some SimpleTimer churn
2005-04-29 jrandom
* Reduce the peer profile stat coallesce overhead by inlining it with the
reorganize.
* Limit each transport to at most one address (any transport that requires
multiple entry points can include those alternatives in the address).
2005-04-28 jrandom
* More fixes for the I2PTunnel "other" interface handling (thanks nelgin!)
* Add back the code to handle bids from multiple transports (though there
is still only one transport enabled by default)
* Adjust the router's queueing of outbound client messages when under
heavy load by running the preparatory job in the client's I2CP handler
thread, thereby blocking additional outbound messages when the router is
hosed.
* No need to validate or persist a netDb entry if we already have it
2005-04-25 smeghead
* Added button to router console for manual update checks.
* Fixed bug in configupdate.jsp that caused the proxy port to be updated
every time the form was submitted even if it hadn't changed.
2005-04-24 jrandom
* Added a pool of PRNGs using a different synchronization technique,
hopefully sufficient to work around IBM's PRNG bugs until we get our
own Fortuna.
* In the streaming lib, don't jack up the RTT on NACK, and have the window
size bound the not-yet-ready messages to the peer, not the unacked
message count (not sure yet whether this is worthwile).
* Many additions to the messageHistory log.
* Handle out of order tunnel fragment delivery (not an issue on the live
net with TCP, but critical with UDP).
2005-04-20 jrandom
* In the SDK, we don't actually need to block when we're sending a message
as BestEffort (and these days, we're always sending BestEffort).
* Pass out client messages in fewer (larger) steps.
* Have the InNetMessagePool short circuit dispatch requests.
* Have the message validator take into account expiration to cut down on
false positives at high transfer rates.
* Allow configuration of the probabalistic window size growth rate in the
streaming lib's slow start and congestion avoidance phases, and default
them to a more conservative value (2), rather than the previous value
(1).
* Reduce the ack delay in the streaming lib to 500ms
* Honor choke requests in the streaming lib (only affects those getting
insanely high transfer rates)
* Let the user specify an interface besides 127.0.0.1 or 0.0.0.0 on the
I2PTunnel client page (thanks maestro^!)
2005-04-17 sirup
* Added the possibility for i2ptunnel client and httpclient instances to
have their own i2p session (and hence, destination and tunnels). By
default, tunnels are shared, but that can be changed on the web
interface or with the sharedClient config option in i2ptunnel.config.
2005-04-17 jrandom
* Marked the net.i2p.i2ptunnel.TunnelManager as deprecated. Anyone use
this? If not, I want to drop it (lots of tiny details with lots of
duplicated semantics).
2005-04-17 zzz
* Added new user-editable eepproxy error page templates.
2005-04-17 jrandom
* Revamp the tunnel building throttles, fixing a situation where the
rebuild may not recover, and defaulting it to unthrottled (users with
slow CPUs may want to set "router.tunnel.shouldThrottle=true" in their
advanced router config)
2005-04-16 jrandom
* Migrated to Bouncycastle's SHA256 and HMAC implementations for efficiency
