    * Expose the HTTP headers to EepGet status listeners
    * Handle DSA key failures properly (if the signature is not invertable, it
      is obviously invalid)

jrandom authored 19 years ago and zzz committed 19 years ago

    * Added the new test Floodfill netDb

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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.

    * 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.

    * If we already have an established SSU session with the Charlie helping
      test us, cancel the test with the status of "unknown".

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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).

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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

    * Backed out an inadvertant change to the netDb store redundancy factor.
    * Verify tunnel participant caching.
    * Logging cleanup

jrandom authored 19 years ago and zzz committed 19 years ago

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.

jrandom authored 19 years ago and zzz committed 19 years ago

    * Use the small thread pool for I2PTunnelHTTPServer (already used for
      I2PTunnelServer)
    * Minor memory churn reduction in I2CP
    * Small stats update

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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"

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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.

jrandom authored 19 years ago and zzz committed 19 years ago

    * Add some data duplication to avoid a recently injected concurrency problem
      in the session tag manager (thanks redzara and romster).

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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.

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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

comwiz authored 19 years ago and zzz committed 19 years ago

    * Phase 1 of the unit test bounty completed. (The router build script was modified not to build the router
 tests because of a broken dependancy on the core tests. This should be fixed in
 phase 3 of the unit test bounty.)

duck authored 19 years ago and zzz committed 19 years ago

    * Fixed PRNG bug (bugzilla #107)

jrandom authored 19 years ago and zzz committed 19 years ago

    * Added a substantial optimization to the AES engine by caching the
      prepared session keys (duh).

jrandom authored 19 years ago and zzz committed 19 years ago

    * Reduced some SimpleTimer churn
* add hooks for per-peer choking in the outbound message queue - if/when a
  peer reaches their cwin, no further messages will enter the 'active' pool
  until there are more bytes available.  other messages waiting (either later
  on in the same priority queue, or in the queues for other priorities) may
  take that slot.
* when we have a message acked, release the acked size to the congestion
  window (duh), rather than waiting for the second to expire and refill the
  capacity.
* send packets in a volley explicitly, waiting until we can allocate the full
  cwin size for that message

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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).
and for udp stuff:
* implemented tcp-esque rto code in the udp transport
* make sure we don't ACK too many messages at once
* transmit fragments in a simple (nonrandom) order so that we can more easily
  adjust timeouts/etc.
* let the active outbound pool grow dynamically if there are outbound slots to
  spare
* use a simple decaying bloom filter at the UDP level to drop duplicate resent
  packets.

jrandom authored 19 years ago and zzz committed 19 years ago

    * 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)

    * Migrated to Bouncycastle's SHA256 and HMAC implementations for efficiency

jrandom authored 19 years ago and zzz committed 19 years ago

    * Migrated to Bouncycastle's SHA256 and HMAC implementations for efficiency
(also lots of udp fixes)

jrandom authored 19 years ago and zzz committed 19 years ago

the basics (negotiate a session and send I2NP messages back and forth).  Lots,
lots more left.

jrandom authored 19 years ago and zzz committed 19 years ago

    * Make sure we don't get cached updates (thanks smeghead!)
    * Clear out the callback for the TestJob after it passes (only affects the
      job timing accounting)
