Pass message timeout through new I2CP message
SendMessageExpiresMessage, so that the router
uses the same expiration as the streaming lib.
Should help reliability.
* I2CP:
Implement new I2CP message ReconfigureSessionMessage.
Will be used for tunnel reduction.
Implement Base32 Hash hostnames, via the naming service.
Names are of the form [52-characters].i2p, where
the 52 characters are the Base32 representation of our
256-byte hash. The client requests a lookup of the hash
via a brief I2CP session using new I2CP request/reply
messages. The router looks up the leaseset for the hash
to convert the hash to a dest. Convert the I2PTunnel
'preview' links to use Base32 hostnames as a
demonstration.
* Delay shitlist cleaner at startup
* Strip wrapper properties from client config
* Define multiple cert type
* Prohibit negative maxSends in streaming
* HTML fixup on configtunnels.jsp
* Increase wrapper exit timeout from default 15s to 30s
* HostsTxtNamingService: Add reverse lookup support
* Outbound message: Minor cleanup
* i2psnark TrackerCLient: Minor cleanup
* checklist.txt: Minor edit
* hosts.txt: Add perv.i2p, false.i2p, mtn.i2p2.i2p
* i2ptunnel.config: Change CVS client to mtn
* netdb.jsp: Show leaseSet destinations using reverse lookup
* profiles.jsp: First cut at showing floodfill data
(was Meta = PetName + HostsTxt)
* Naming: Add two new experimental NamingServices, EepGet and Exec,
not enabled by default -
see source comments in core/java/src/net/i2p/client/naming
for configuration instructions
* Major SSU and router tuning to reduce contention, memory usage, and GC
churn. There are still issues to be worked out, but this should be a
substantial improvement.
* Modified the optional netDb harvester task to support choosing whether
to use (non-anonymous) direct connections or (anonymous) exploratory
tunnels to do the harvesting. Harvesting itself is enabled via the
advanced config "netDb.shouldHarvest=true" (default is false) and the
connection type can be chosen via "netDb.harvestDirectly=false" (default
is false).
* Fix for old Syndie blog bookmarks (thanks Complication!)
* Fix for I2PSnark to accept incoming connections again (oops)
* Randomize the order that peers from the tracker are contacted
* IE doesn't strip SPAN from <button> form fields, so add in a workaround
within I2PTunnel.
* Increase the maximum SSU retransmission timeout to accomodate slower or
more congested links (though SSU's RTO calculation will usually use a
much lower timeout)
* Moved the streaming lib timed events off the main timer queues and onto
a streaming lib specific set of timer queues. Streaming lib timed
events are more likely to have lock contention on the I2CP socket while
other timed events in the router are (largely) independent.
* Fixed a case sensitive lookup bug (thanks tino!)
* Syndie cleanup - new edit form on the preview page, and fixed some blog
links (thanks tino!)
* Defer netDb searches for newly referenced peers until we actually want
them
* Ignore netDb references to peers on our shitlist
* Set the timeout for end to end client messages to the max delay after
finding the leaseSet, so we don't have as many expired messages floating
around.
* Add a floor to the streaming lib window size
* When we need to send a streaming lib ACK, try to retransmit one of the
unacked packets instead (with updated ACK/NACK fields, of course). The
bandwidth cost of an unnecessary retransmission should be minor as
compared to both an ACK packet (rounded up to 1KB in the tunnels) and
the probability of a necessary retransmission.
* Adjust the streaming lib cwin algorithm to allow growth after a full
cwin messages if the rtt is trending downwards. If it is not, use the
existing algorithm.
* Increased the maximum rto size in the streaming lib.
* Load balancing bugfix on end to end messages to distribute across
tunnels more evenly.
* I2PTunnel bugfix (thanks Complication!)
* Increase the SSU cwin slower during congestion avoidance (at k/cwin^2
instead of k/cwin)
* Limit the number of inbound SSU sessions being built at once (using
half of the i2np.udp.maxConcurrentEstablish config prop)
* Don't shitlist on a message send failure alone (unless there aren't any
common transports).
* More careful bandwidth bursting
* Better i2paddresshelper handling in the I2PTunnel httpclient, plus a new
conflict resolution page if the i2paddresshelper parameter differs from
an existing name to destination mapping.

* Fix a long standing streaming lib bug (in the inactivity detection code)
* Improved handling of initial streaming lib packet retransmissions to
kill the "lost first packet" bug (where a page shows up with the first
few KB missing)
* Add support for initial window sizes greater than 1 - useful for
eepsites to transmit e.g. 4 packets full of data along with the initial
ACK, thereby cutting down on the rtt latency. The congestion window
size can and does still shrink down to 1 packet though.
* Adjusted the streaming lib retransmission calculation algorithm to be
more TCP-like.
* Removed guaranteed delivery mode entirely (so existing i2phex clients
using it can get the benefits of mode=best_effort). Guaranteed delivery
is offered at the streaming lib level.
* Improve the peer selection code for peer testing, as everyone now
supports tests.
* Give the watchdog its fangs - if it detects obscene job lag or if
clients have been unable to get a leaseSet for more than 5 minutes,
restart the router. This was disabled a year ago due to spurious
restarts, and can be disabled by "watchdog.haltOnHang=false", but the
cause of the spurious restarts should be gone.

* 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.
* 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
* 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
* 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^!)
(plus minor udp tweaks)
2005-03-18 jrandom
* Minor tweak to the timestamper to help reduce small skews
* Adjust the stats published to include only the relevent ones
* Only show the currently used speed calculation on the profile page
* Allow the full max # resends to be sent, rather than piggybacking the
RESET packet along side the final resend (duh)
* Add irc.postman.i2p to the default list of IRC servers for new installs
* Drop support for routers running 0.5 or 0.5.0.1 while maintaining
backwards compatability for users running 0.5.0.2.
* Fix one substantial OOM cause (session tag manager was only dropping
tags once the critical limit was met, rather than honoring their
expiration) (duh)
* Lots of small memory fixes
* Double the allowable concurrent outstanding tunnel build tasks (20)
