+Changes in version 0.2.9.5-alpha - 2016-11-08
|
|
|
|
+ Tor 0.2.9.5-alpha fixes numerous bugs discovered in the previous alpha
|
|
|
|
+ version. We believe one or two probably remain, and we encourage
|
|
|
|
+ everyone to test this release.
|
|
|
|
+
|
|
|
|
+ o Major bugfixes (client performance):
|
|
|
|
+ - Clients now respond to new application stream requests immediately
|
|
|
|
+ when they arrive, rather than waiting up to one second before
|
|
|
|
+ starting to handle them. Fixes part of bug 19969; bugfix
|
|
|
|
+ on 0.2.8.1-alpha.
|
|
|
|
+
|
|
|
|
+ o Major bugfixes (client reliability):
|
|
|
|
+ - When Tor leaves standby because of a new application request, open
|
|
|
|
+ circuits as needed to serve that request. Previously, we would
|
|
|
|
+ potentially wait a very long time. Fixes part of bug 19969; bugfix
|
|
|
|
+ on 0.2.8.1-alpha.
|
|
|
|
+
|
|
|
|
+ o Major bugfixes (download scheduling):
|
|
|
|
+ - When using an exponential backoff schedule, do not give up on
|
|
|
|
+ downloading just because we have failed a bunch of times. Since
|
|
|
|
+ each delay is longer than the last, retrying indefinitely won't
|
|
|
|
+ hurt. Fixes bug 20536; bugfix on 0.2.9.1-alpha.
|
|
|
|
+ - If a consensus expires while we are waiting for certificates to
|
|
|
|
+ download, stop waiting for certificates.
|
|
|
|
+ - If we stop waiting for certificates less than a minute after we
|
|
|
|
+ started downloading them, do not consider the certificate download
|
|
|
|
+ failure a separate failure. Fixes bug 20533; bugfix
|
|
|
|
+ on 0.2.0.9-alpha.
|
|
|
|
+ - Remove the maximum delay on exponential-backoff scheduling. Since
|
|
|
|
+ we now allow an infinite number of failures (see ticket 20536), we
|
|
|
|
+ must now allow the time to grow longer on each failure. Fixes part
|
|
|
|
+ of bug 20534; bugfix on 0.2.9.1-alpha.
|
|
|
|
+ - Make our initial download delays closer to those from 0.2.8. Fixes
|
|
|
|
+ another part of bug 20534; bugfix on 0.2.9.1-alpha.
|
|
|
|
+ - When determining when to download a directory object, handle times
|
|
|
|
+ after 2038 if the operating system supports them. (Someday this
|
|
|
|
+ will be important!) Fixes bug 20587; bugfix on 0.2.8.1-alpha.
|
|
|
|
+ - When using exponential backoff in test networks, use a lower
|
|
|
|
+ exponent, so the delays do not vary as much. This helps test
|
|
|
|
+ networks bootstrap consistently. Fixes bug 20597; bugfix on 20499.
|
|
|
|
+
|
|
|
|
+ o Minor features (geoip):
|
|
|
|
+ - Update geoip and geoip6 to the November 3 2016 Maxmind GeoLite2
|
|
|
|
+ Country database.
|
|
|
|
+
|
|
|
|
+ o Minor bugfixes (client directory scheduling):
|
|
|
|
+ - Treat "relay too busy to answer request" as a failed request and a
|
|
|
|
+ reason to back off on our retry frequency. This is safe now that
|
|
|
|
+ exponential backoffs retry indefinitely, and avoids a bug where we
|
|
|
|
+ would reset our download schedule erroneously. Fixes bug 20593;
|
|
|
|
+ bugfix on 0.2.9.1-alpha.
|
|
|
|
+
|
|
|
|
+ o Minor bugfixes (client, logging):
|
|
|
|
+ - Remove a BUG warning in circuit_pick_extend_handshake(). Instead,
|
|
|
|
+ assume all nodes support EXTEND2. Use ntor whenever a key is
|
|
|
|
+ available. Fixes bug 20472; bugfix on 0.2.9.3-alpha.
|
|
|
|
+ - On DNSPort, stop logging a BUG warning on a failed hostname
|
|
|
|
+ lookup. Fixes bug 19869; bugfix on 0.2.9.1-alpha.
|
|
|
|
+
|
|
|
|
+ o Minor bugfixes (hidden services):
|
|
|
|
+ - When configuring hidden services, check every hidden service
|
|
|
|
+ directory's permissions. Previously, we only checked the last
|
|
|
|
+ hidden service. Fixes bug 20529; bugfix the work to fix 13942
|
|
|
|
+ in 0.2.6.2-alpha.
|
|
|
|
+
|
|
|
|
+ o Minor bugfixes (portability):
|
|
|
|
+ - Fix compilation with OpenSSL 1.1 and less commonly-used CPU
|
|
|
|
+ architectures. Closes ticket 20588.
|
|
|
|
+ - Use ECDHE ciphers instead of ECDH in tortls tests. LibreSSL has
|
|
|
|
+ removed the ECDH ciphers which caused the tests to fail on
|
|
|
|
+ platforms which use it. Fixes bug 20460; bugfix on 0.2.8.1-alpha.
|
|
|
|
+ - Fix implicit conversion warnings under OpenSSL 1.1. Fixes bug
|
|
|
|
+ 20551; bugfix on 0.2.1.1-alpha.
|
|
|
|
+
|
|
|
|
+ o Minor bugfixes (relay bootstrap):
|
|
|
|
+ - Ensure relays don't make multiple connections during bootstrap.
|
|
|
|
+ Fixes bug 20591; bugfix on 0.2.8.1-alpha.
|
|
|
|
+
|
|
|
|
+ o Minor bugfixes (relay):
|
|
|
|
+ - Work around a memory leak in OpenSSL 1.1 when encoding public
|
|
|
|
+ keys. Fixes bug 20553; bugfix on 0.0.2pre8.
|
|
|
|
+ - Avoid a small memory leak when informing worker threads about
|
|
|
|
+ rotated onion keys. Fixes bug 20401; bugfix on 0.2.6.3-alpha.
|
|
|
|
+ - Do not try to parallelize workers more than 16x without the user
|
|
|
|
+ explicitly configuring us to do so, even if we do detect more than
|
|
|
|
+ 16 CPU cores. Fixes bug 19968; bugfix on 0.2.3.1-alpha.
|
|
|
|
+
|
|
|
|
+ o Minor bugfixes (single onion services):
|
|
|
|
+ - Start correctly when creating a single onion service in a
|
|
|
|
+ directory that did not previously exist. Fixes bug 20484; bugfix
|
|
|
|
+ on 0.2.9.3-alpha.
|
|
|
|
+
|
|
|
|
+ o Minor bugfixes (testing):
|
|
|
|
+ - Avoid a unit test failure on systems with over 16 detectable CPU
|
|
|
|
+ cores. Fixes bug 19968; bugfix on 0.2.3.1-alpha.
|
|
|
|
+
|
|
|
|
+ o Documentation:
|
|
|
|
+ - Clarify that setting HiddenServiceNonAnonymousMode requires you to
|
|
|
|
+ also set "SOCKSPort 0". Fixes bug 20487; bugfix on 0.2.9.3-alpha.
|
|
|
|
+ - Module-level documentation for several more modules. Closes
|
|
|
|
+ tickets 19287 and 19290.
