* Bugfix for the auto-update code to handle different usage patterns * Decreased the addressbook recheck frequency to once every 12 hours instead of hourly. * Handle dynamically changing the HMAC size (again, unless your nym is toad or jrandom, ignore this ;) * Cleaned up some synchronization/locking code

* Support noreseed.i2p in addition to .i2pnoreseed for disabling automatic reseeding - useful on OSes that make it hard to create dot files. Thanks Complication (and anon)! * Fixed the installer version string (thanks Frontier!) * Added cleaner rejection of invalid IP addresses, shitlist those who send us invalid IP addresses, verify again that we are not sending invalid IP addresses, and log an error if it happens. (Thanks Complication, ptm, and adab!)

2005-09-29 jrandom * Let syndie users modify their metadata. * Reseed the router on startup if there aren't enough peer references known locally. This can be disabled by creating the file .i2pnoreseed in your home directory, and the existing detection and reseed handling on the web interface is unchanged.

* Allow reseeding on the console if the netDb knows less than 30 peers, rather than less than 10 (without internet connectivity, we keep the last 15 router references) * Reenable the x-i2p-gzip HTTP processing by default, flushing the stream more aggressively. * Show the status that used to be called "ERR-Reject" as "OK (NAT)" * Reduced the default maximum number of streaming lib resends of a packet (10 retransmits is a bit much with a reasonable RTO)

* Updated the bandwidth limiter to use two tiers of bandwidth - our normal steady state rate, plus a new limit on how fast we transfer when bursting. This is different from the old "burst as fast as possible until we're out of tokens" policy, and should help those with congested networks. See /config.jsp to manage this rate. * Bugfixes in Syndie to handle missing cache files (no data was lost, the old posts just didn't show up). * Log properly in EepPost

* More aggressively publish updated routerInfo. * Expose the flag to force SSU introductions on the router console * Don't give people the option to disable SNTP time sync, at least not through the router console, because there is no reason to disable it. No, not even if your OS is "ntp synced", because chances are, its not.

* Test the router's reachability earlier and more aggressively * Use the low level bandwidth limiter's rates for the router console, and if the router has net.i2p.router.transport.FIFOBandwidthLimiter=INFO in the logger config, keep track of the 1 second transfer rates as the stat 'bw.sendBps1s' and 'bw.recvBps1s', allowing closer monitoring of burst behavior.

* Expose the HTTP headers to EepGet status listeners * Handle DSA key failures properly (if the signature is not invertable, it is obviously invalid) also, syndie now properly detects whether the remote archive can send a filtered export.zip by examining the HTTP headers for X-Syndie-Export-Capable: true. If the remote archive does not set that header (and neither freesites, nor apache or anything other than the ArchiveServlet will), it uses individual HTTP requests for individual blog posts and metadata fetches.

* 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.

* 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.

2005-07-27 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.

* 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

* Security improvements to TrustedUpdate: signing and verification of the version string along with the data payload for signed update files (consequently the positions of the DSA signature and version string fields have been swapped in the spec for the update file's header); router will no longer perform a trusted update if the signed update's version is lower than or equal to the currently running router's version. * Added two new CLI commands to TrustedUpdate: showversion, verifyupdate. * Extended TrustedUpdate public API for use by third party applications.

* After a successfull netDb search for a leaseSet, republish it to all of the peers we have tried so far who did not give us the key (up to 10), rather than the old K closest (which may include peers who had given us the key) * Don't wait 5 minutes to publish a leaseSet (duh!), and rather than republish it every 5 minutes, republish it every 3. In addition, always republish as soon as the leaseSet changes (duh^2). * Minor fix for oddball startup race (thanks travis_bickle!) * Minor AES update to allow in-place decryption.

2005-03-29 jrandom * Decreased the initial RTT estimate to 10s to allow more retries. * Increased the default netDb store replication factor from 2 to 6 to take into consideration tunnel failures. * Address some statistical anonymity attacks against the netDb that could be mounted by an active internal adversary by only answering lookups for leaseSets we received through an unsolicited store. * Don't throttle lookup responses (we throttle enough elsewhere) * Fix the NewsFetcher so that it doesn't incorrectly resume midway through the file (thanks nickster!) * Updated the I2PTunnel HTML (thanks postman!) * Added support to the I2PTunnel pages for the URL parameter "passphrase", which, if matched against the router.config "i2ptunnel.passphrase" value, skips the nonce check. If the config prop doesn't exist or is blank, no passphrase is accepted. * Implemented HMAC-SHA256. * Enable the tunnel batching with a 500ms delay by default * Dropped compatability with 0.5.0.3 and earlier releases

* Implemented the news fetch / update policy code, as configurated on /configupdate.jsp. Defaults are to grab the news every 24h (or if it doesn't exist yet, on startup). No action is taken however, though if the news.xml specifies that a new release is available, an option to update will be shown on the router console. * New initialNews.xml delivered with new installs, and moved news.xml out of the i2pwww module and into the i2p module so that we can bundle it within each update.

* New /configupdate.jsp page for controlling the update / notification process, as well as various minor related updates. Note that not all options are exposed yet, and the update detection code isn't in place in this commit - it currently says there is always an update available. * New EepGet component for reliable downloading, with a CLI exposed in java -cp lib/i2p.jar net.i2p.util.EepGet url * Added a default signing key to the TrustedUpdate component to be used for verifying updates. This signing key can be authenticated via gpg --verify i2p/core/java/src/net/i2p/crypto/TrustedUpdate.java * New public domain SHA1 implementation for the DSA code so that we can handle signing streams of arbitrary size without excess memory usage (thanks P.Verdy!) * Added some helpers to the TrustedUpdate to work off streams and to offer a minimal CLI: TrustedUpdate keygen pubKeyFile privKeyFile TrustedUpdate sign origFile signedFile privKeyFile TrustedUpdate verify signedFile

* Adjust the old speed calculator to include end to end RTT data in its estimates, and use that as the primary speed calculator again. * Use the mean of the high capacity speeds to determine the fast threshold, rather than the median. Perhaps we should use the mean of all active non-failing peers? * Updated the profile page to sort by tier, then alphabetically. * Added some alternative socketManager factories (good call aum!)

* Really disable the streaming lib packet caching * Synchronized a message handling point in the SDK (even though its use is already essentially single threaded, its better to play it safe) * Don't add new RepublishLeaseSetJobs on failure, just requeue up the existing one (duh) * Throttle the number of concurrent pending tunnel builds across all pools, in addition to simply throttling the number of new requests per minute for each pool individually. This should avoid the cascading failure when tunnel builds take too long, as no new builds will be created until the previous ones are handled. * Factored out and extended the DataHelper's unit tests for dealing with long and date formatting. * Explicitly specify the HTTP auth realm as "i2prouter", though this alone doesn't address the bug where jetty asks for authentication too much. (thanks orion!) * Updated the StreamSinkServer to ignore all read bytes, rather than write them to the filesystem.

* Adjusted (and fixed...) the timestamper change detection * Deal with a rare reordering bug at the beginning of a stream (so we don't drop it unnecessarily) * Cleaned up some dropped message handling in the router * Reduced job queue churn when dealing with a large number of tunnels by sharing an expiration job * Keep a separate list of the most recent CRIT messages (shown on the logs.jsp). This way they don't get buried among any other messages. * For clarity, display the tunnel variance config as "Randomization" on the web console. * If lease republishing fails (boo! hiss!) try it again * Actually fix the negative jobLag in the right place (this time) * Allow reseeding when there are less than 10 known peer references * Lots of logging updates.

* Allow the streaming lib resend frequency to drop down to 20s as the minimum, so that up to 2 retries can get sent on an http request. * Add further limits to failsafe tunnels. * Keep exploratory and client tunnel testing and building stats separate. * Only use the 60s period for throttling tunnel requests due to transient network overload. * Rebuild tunnels earlier (1-3m before expiration, by default) * Cache the next hop's routerInfo for participating tunnels so that the tunnel participation doesn't depend on the netDb. * Fixed a long standing bug in the streaming lib where we wouldn't always unchoke messages when the window size grows. * Make sure the window size never reaches 0 (duh)

* (Merged the 0.5-pre branch back into CVS HEAD) * Replaced the old tunnel routing crypto with the one specified in router/doc/tunnel-alt.html, including updates to the web console to view and tweak it. * Provide the means for routers to reject tunnel requests with a wider range of responses: probabalistic rejection, due to approaching overload transient rejection, due to temporary overload bandwidth rejection, due to persistent bandwidth overload critical rejection, due to general router fault (or imminent shutdown) The different responses are factored into the profiles accordingly. * Replaced the old I2CP tunnel related options (tunnels.depthInbound, etc) with a series of new properties, relevent to the new tunnel routing code: inbound.nickname (used on the console) inbound.quantity (# of tunnels to use in any leaseSets) inbound.backupQuantity (# of tunnels to keep in the ready) inbound.length (# of remote peers in the tunnel) inbound.lengthVariance (if > 0, permute the length by adding a random # up to the variance. if < 0, permute the length by adding or subtracting a random # up to the variance) outbound.* (same as the inbound, except for the, uh, outbound tunnels in that client's pool) There are other options, and more will be added later, but the above are the most relevent ones. * Replaced Jetty 4.2.21 with Jetty 5.1.2 * Compress all profile data on disk. * Adjust the reseeding functionality to work even when the JVM's http proxy is set. * Enable a poor-man's interactive-flow in the streaming lib by choking the max window size. * Reduced the default streaming lib max message size to 16KB (though still configurable by the user), also doubling the default maximum window size. * Replaced the RouterIdentity in a Lease with its SHA256 hash. * Reduced the overall I2NP message checksum from a full 32 byte SHA256 to the first byte of the SHA256. * Added a new "netId" flag to let routers drop references to other routers who we won't be able to talk to. * Extended the timestamper to get a second (or third) opinion whenever it wants to actually adjust the clock offset. * Replaced that kludge of a timestamp I2NP message with a full blown DateMessage. * Substantial memory optimizations within the router and the SDK to reduce GC churn. Client apps and the streaming libs have not been tuned, however. * More bugfixes thank you can shake a stick at. 2005-02-13 jrandom * Updated jbigi source to handle 64bit CPUs. The bundled jbigi.jar still only contains 32bit versions, so build your own, placing libjbigi.so in your install dir if necessary. (thanks mule!) * Added support for libjbigi-$os-athlon64 to NativeBigInteger and CPUID (thanks spaetz!)
