Changes in version 0.2.6.2-alpha - 2014-12-??
-
Tor 0.2.6.2-alpha is the second alpha release in the 0.2.6.x series.
+ o Major features (relay, infrastructure): - Implement a new inter-cmux
+ comparison API, a global high/low watermark mechanism and a global
+ scheduler loop for transmission prioritization across all channels as
+ well as among circuits on one channel. This schedule is currently
+ tuned to (tolerantly) avoid making changes in the current network
+ performance, but it should form the basis major circuit performance
+ increases. Code by Andrea; implements ticket 9262.
+
+ o Testing: - New tests for many parts of channel, relay, and circuit
+ mux functionality. Code by Andrea; part of 9262.
+
o Major features (hidden services):
- Add a HiddenServiceStatistics option that allows Tor relays to
gather and publish statistics about hidden service usage, to
better understand the size and volume of the hidden service
- network. Specifically, if a Tor relay is an HSDir it will
- publish the approximate number of hidden services that have
- published descriptors to it the past 24 hours. Also, if a relay
- has acted as a hidden service rendezvous point, it will publish
- the approximate amount of rendezvous cells it has relayed the
- past 24 hours. The statistics themselves are obfuscated so that
- the exact values cannot be derived. For more details see
- proposal 238 "Better hidden service stats from Tor relays". This
- feature is currently disabled by default. Implements feature 13192.

o Major bugfixes:
- - When closing an introduction circuit that was opened in
- parallel, don't mark the introduction point as
- unreachable. Previously, the first successful connection to an
- introduction point would make the other uintroduction points get
- marked as having timed out. Fixes bug 13698; bugfix on 0.0.6rc2.

+ Fixes bug 13698; bugfix on 0.0.6rc2.
o Minor feature:
- - When re-enabling the network, don't try to build introduction circuits
- until we have successfully built a circuit. This makes hidden services
- come up faster when the network is re-enabled. Patch from
- "akwizgran". Closes ticket 13447.

+
+ o Minor features:
+ - OS X uses ipfw (FreeBSD) or pf (OpenBSD). Update the transparent
+ proxy option checks to allow for both ipfw and pf on OS X. Closes
+ ticket 14002.

+ - Validate hostnames in SOCKS5 requests more strictly. If SafeSocks
+ is enabled, reject requests with IP addresses as hostnames.

+ o Minor bugfixes:
+ - Silence clang warnings under --enable-expensive-hardening,
+ including: implicit truncation of 64 bit values to 32 bit; const
+ char assignment to self; tautological compare; and additional
+ parentheses around equality tests. Fixes bug 13577; bugfix
+ on 0.2.5.4-alpha.
+ - Stop allowing invalid address patterns containing both a wildcard
+ address and a bit prefix length. This affects all our address-
+ range parsing code. Fixes bug 7484; bugfix on 0.0.2pre14.
+ - The address of an array in the middle of a structure will always
+ be non-NULL. clang recognises this and complains. Disable the
+ tautologous and redundant check to silence this warning. Fixes bug
+ 14001; bugfix on 0.2.1.2-alpha.
+ - Use a full 256 bits of the SHA256 digest of a microdescriptor when
+ computing which microdescriptors to download. This keeps us from
+ erroneous download behavior if two microdescriptor digests ever
+ have the same first 160 bits. Fixes part of bug 13399; bugfix

+ - Reset a router's status if its microdescriptor digest changes,
+ even if the first 160 bits remain the same. Fixes part of bug
+ 13399; bugfix on 0.2.3.1-alpha.
+ - Use circuit_has_opened() instead of
+ rend_client_rendcirc_has_opened() when a rendezvous circuit is
+ opened because circuit_has_opened() jobs is to call a specialized
+ function depending on the circuit purpose. Furthermore, a
+ controller event will be triggered here where the former did not.
