* HTML cleanup for the router console (thanks!)
2005-09-07 jrandom
* Lay the foundation for 'client routers' - the ability for peers to opt
out of participating in tunnels entirely due to firewall/NAT issues.
Individual routers have control over where those peers are used in
tunnels - in outbound or inbound, exploratory or client tunnels, or
none at all. The defaults with this build are to simply act as before -
placing everyone as potential participants in any tunnel.
* Another part of the foundation includes the option for netDb
participants to refuse to answer queries regarding peers who are marked
as unreachable, though this too is disabled by default (meaning the
routerInfo is retrievable from the netDb).
2005-09-05 jrandom
* Expose the HTTP headers to EepGet status listeners
* Handle DSA key failures properly (if the signature is not invertable, it
is obviously invalid)
2005-09-04 jrandom
* Don't persist peer profiles until we are shutting down, as the
persistence process gobbles RAM and wall time.
* Bugfix to allow you to check/uncheck the sharedClient setting on the
* Be more careful when expiring a failed tunnel message fragment so we
don't drop the data while attempting to read it.
2005-09-02 jrandom
* Don't refuse to send a netDb store if the targetted peer has failed a
bit (the value was an arbitrary amount).
* Logging changes
2005-09-01 jrandom
* Don't send out a netDb store of a router if it is more than a few hours
old, even if someone asked us for it.
2005-08-31 jrandom
* Don't publish leaseSets to the netDb if they will never be looked for -
namely, if they are for destinations that only establish outbound
streams. I2PTunnel's 'client' and 'httpclient' proxies have been
modified to tell the router that it doesn't need to publish their
leaseSet (by setting the I2CP config option 'i2cp.dontPublishLeaseSet'
to 'true').
* Don't publish the top 10 peer rankings of each router in the netdb, as
it isn't being watched right now.
2005-08-29 jrandom
* Added the new test Floodfill netDb
2005-08-27 jrandom
* Minor logging and optimization tweaks in the router and SDK
* Use ISO-8859-1 in the XML files (thanks redzara!)
* The consolePassword config property can now be used to bypass the router
console's nonce checking, allowing CLI restarts
2005-08-24 jrandom
* Catch errors with corrupt tunnel messages more gracefully (no need to
kill the thread and cause an OOM...)
* Don't skip shitlisted peers for netDb store messages, as they aren't
necessarily shitlisted by other people (though they probably are).
* Adjust the netDb store per-peer timeout based on each particular peer's
profile (timeout = 4x their average netDb store response time)
* Don't republish leaseSets to *failed* peers - send them to peers who
replied but just didn't know the value.
* Set a 5 second timeout on the I2PTunnelHTTPServer reading the client's
HTTP headers, rather than blocking indefinitely. HTTP headers should be
sent entirely within the first streaming packet anyway, so this won't be
a problem.
* Don't use the I2PTunnel*Server handler thread pool by default, as it may
prevent any clients from accessing the server if the handlers get
blocked by the streaming lib or other issues.
* Don't overwrite a known status (OK/ERR-Reject/ERR-SymmetricNAT) with
Unknown.
2005-08-23 jrandom
* Removed the concept of "no bandwidth limit" - if none is specified, its
16KBps in/out.
* Include ack packets in the per-peer cwin throttle (they were part of the
bandwidth limit though).
* Tweak the SSU cwin operation to get more accurrate estimates under
congestions.
* SSU improvements to resend more efficiently.
* Added a basic scheduler to eepget to fetch multiple files sequentially.
* 2005-08-21 0.6.0.3 released
2005-08-21 jrandom
* If we already have an established SSU session with the Charlie helping
test us, cancel the test with the status of "unknown".
2005-08-17 jrandom
* Revise the SSU peer testing protocol so that Bob verifies Charlie's
viability before agreeing to Alice's request. This doesn't work with
older SSU peer test builds, but is backwards compatible (older nodes
won't ask newer nodes to participate in tests, and newer nodes won't
ask older nodes to either).
2005-08-12 jrandom
* Keep detailed stats on the peer testing, publishing the results in the
netDb.
* Don't overwrite the status with 'unknown' unless we haven't had a valid
status in a while.
* Make sure to avoid shitlisted peers for peer testing.
* When we get an unknown result to a peer test, try again soon afterwards.
* When a peer tells us that our address is different from what we expect,
if we've done a recent peer test with a result of OK, fire off a peer
test to make sure our IP/port is still valid. If our test is old or the
result was not OK, accept their suggestion, but queue up a peer test for
later.
* Don't try to do a netDb store to a shitlisted peer, and adjust the way
we monitor netDb store progress (to clear up the high netDb.storePeers
stat)
2005-08-10 jrandom
* Deployed the peer testing implementation to be run every few minutes on
each router, as well as any time the user requests a test manually. The
tests do not reconfigure the ports at the moment, merely determine under
what conditions the local router is reachable. The status shown in the
top left will be "ERR-SymmetricNAT" if the user's IP and port show up
differently for different peers, "ERR-Reject" if the router cannot
receive unsolicited packets or the peer helping test could not find a
collaborator, "Unknown" if the test has not been run or the test
participants were unreachable, or "OK" if the router can receive
unsolicited connections and those connections use the same IP and port.
* 2005-08-08 0.6.0.2 released
2005-08-08 jrandom
* Add a configurable throttle to the number of concurrent outbound SSU
connection negotiations (via i2np.udp.maxConcurrentEstablish=4). This
may help those with slow connections to get integrated at the start.
* Further fixlets to the streaming lib
2005-08-07 Complication
* Display the average clock skew for both SSU and TCP connections
2005-08-07 jrandom
* Fixed the long standing streaming lib bug where we could lose the first
packet on retransmission.
* Avoid an NPE when a message expires on the SSU queue.
* Adjust the streaming lib's window growth factor with an additional
Vegas-esque congestion detection algorithm.
* Removed an unnecessary SSU session drop
* Reduced the MTU (until we get a working PMTU lib)
* Deferr tunnel acceptance until we know how to reach the next hop,
rejecting it if we can't find them in time.
* If our netDb store of our leaseSet fails, give it a few seconds before
republishing.
* 2005-08-03 0.6.0.1 released
2005-08-03 jrandom
* Backed out an inadvertant change to the netDb store redundancy factor.
* Verify tunnel participant caching.
* Logging cleanup
2005-08-01 duck
* Update IzPack to 3.7.2 (build 2005.04.22). This fixes bug #82.
2005-08-01 duck
* Fix an addressbook NPE when a new hostname from the master addressbook
didn't exist in the router addressbook.
* Fix an addressbook bug which caused subscriptions not to be parsed at
all. (Oops!)
2005-07-31 jrandom
* Adjust the netDb search and store per peer timeouts to match the average
measured per peer success times, rather than huge fixed values.
* Optimized and reverified the netDb peer selection / retrieval process
within the kbuckets.
* Drop TCP connections that don't have any useful activity in 10 minutes.
* If i2np.udp.fixedPort=true, never change the externally published port,
even if we are autodetecting the IP address.
* 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.
