Changes in version 0.2.5.3-alpha - 2014-03-??
|
||||
|
||||
o Major features:
|
||||
- Also consider stream buffer sizes when calculating OOM
|
||||
conditions. Rename MaxMemInCellQueues to MaxMemInQueues. Fixes
|
||||
bug 10169.
|
||||
|
||||
o Minor bugfixes:
|
||||
- Exit immediately when exiting because of dropped connection from
|
||||
a process-owning controller. Previously, if we were running in
|
||||
server mode, we would wait for a little while as in the when we
|
||||
got an INT signal--but this was problematic, since there was no
|
||||
feedback for the user. Controllers that want to do a clean
|
||||
shutdown should send an INT signal, and let the user know what's
|
||||
going on. Fix for bug 10449; bugfix on 0.2.2.28-beta.
|
||||
|
||||
o Minor bugfixes:
|
||||
- Log an improved message when excluding hidden service directory
|
||||
nodes prevents a hidden service from working.
|
||||
Improves on our fix for bug #10722, which was a bugfix on
|
||||
0.2.0.10-alpha.
|
||||
|
||||
o Removed code
|
||||
- Remove all code for hidden service authorities to accept and serve
|
||||
version 0 descriptors and left-over code for hidden services and
|
||||
hidden service clients to upload and fetch version 0 descriptors.
|
||||
Version 0 descriptors are not in use anymore since 0.2.2.1-alpha.
|
||||
Fixes the rest of bug 10841.
|
||||
|
||||
o Minor features:
|
||||
- Bridges write the SHA1 digest of their identity key fingerprint to
|
||||
notice-level logs and to hashed-fingerprint, so that bridge
|
||||
operators can look up their bridge in Globe and similar tools.
|
||||
|
||||
o Minor bugfixes (new since 0.2.5.2-alpha, also in 0.2.4.21):
|
||||
- Build without warnings under clang 3.4. (We have some macros that
|
||||
define static functions only some of which will get used later in
|
||||
the module. Starting with clang 3.4, these give a warning unless the
|
||||
unused attribute is set on them.) Resolves ticket 10904.
|
||||
- Fix build warnings about missing "a2x" comment when building the
|
||||
manpages from scratch on OpenBSD; OpenBSD calls it "a2x.py".
|
||||
Fixes bug 10929; bugfix on 0.2.2.9-alpha. Patch from Dana Koch.
|
||||
|
||||
o Minor bugfixes (unit tests);
|
||||
- Fix a small bug in the unit tests that might have made the tests
|
||||
call 'chmod' with an uninitialized bitmask.
|
||||
Fixes bug 10928; bugfix on 0.2.5.1-alpha. Patch from Dana Koch.
|
||||
|
||||
o Minor bugfixes
|
||||
- Fix IPv6 support when using the SocksPort with SOCKS5. Using IPv6
|
||||
through a SOCKS5 using the SocksPort option will now work with
|
||||
this fix. This part of the code has never been updated to support
|
||||
IPv6 thus this does not fix a previously introduced regression.
|
||||
Fixes bug 10987; bugfix on 0.2.4.7-alpha.
|
||||
|
||||
o Minor features (log messages):
|
||||
- Improve the message that gets displayed when Tor as a bridge is
|
||||
using pluggable transports but doesn't have an Extended ORPort
|
||||
listener. Furthermore, we now log the message in the log file
|
||||
too. Resolves ticket 11043.
|
||||
|
||||
o Minor bugfixes:
|
||||
- Build using the -fasynchronous-unwind-tables option so that more
|
||||
platforms (in particular, ones like 32-bit Intel where the
|
||||
-fomit-frame-pointer option is on by default and table
|
||||
generation is not) will support generating backtraces. This
|
||||
doesn't yet add Windows support yet; only Linux, OSX, and some BSD
|
||||
are affected. Reported by 'cypherpunks'; fixes bug 11047; bugfix
|
||||
on 0.2.5.2-alpha.
|
||||
|
||||
o Minor bugfixes:
|
||||
- Avoid strange behavior if two threads hit failed asswertions
|
||||
at the same time and both try to log backtraces at
|
||||
once. (Previously, if this had happened, both threads would
|
||||
have stored their intermediate results in the same buffer, and
|
||||
generated junk outputs.) Reported by "cypherpunks". Fixes bug
|
||||
11048; bugfix on 0.2.5.2-alpha.
|
||||
|
||||
o Minor bugfixes (clients):
|
||||
- Fix tor so that it raises a control port warning when we fail to
|
||||
connect to all of our bridges. Fixes bug 11069; bugfix on
|
||||
tor-0.2.1.2-alpha.
|
||||
|
||||
o Minor features:
|
||||
- Warn the user if they put any ports in the SocksPolicy,
|
||||
DirPolicy, AuthDirReject, AuthDirInvalid, AuthDirBadDir, or
|
||||
AuthDirBadExit options. Fixes ticket #11108.
|
||||
|
||||
o Documentation:
|
||||
- Explain that SocksPolicy, DirPolicy, and their allies don't take
|
||||
port arguments. Fixes ticket #11108.
|
||||
|
||||
o Documentation:
|
||||
- Fix the max client name length in the manpage's description of
|
||||
HiddenServiceAuthorizeClient description: it should have been
|
||||
16, not 19. Fixes bug 11118; bugfix on 0.2.1.6-alpha.
|
||||
|
||||
o Minor bugfixes (clients):
|
||||
- Fix a bug where we would attempt to connect to bridges before
|
||||
our pluggable transports were configured, which resulted in some
|
||||
erroneous log messages. Fixes bug 11156; bugfix on
|
||||
0.2.3.2-alpha.
|
||||
|
||||
o Minor features:
|
||||
- Don't log at warning severity when we refuse to launch a
|
||||
pluggable transport proxy that we don't need. Resolves ticket
|
||||
5018; bugfix on 0.2.5.2-alpha.
|
||||
|
||||
o Minor bugfixes:
|
||||
- Bridges now never collect statistics that were designed for relays.
|
||||
Fix for bug 5824; bugfix on 0.2.3.8-alpha.
|
||||
|
||||
o Minor bugfixes:
|
||||
- Bridges now report complete directory request statistics. Related to
|
||||
bug 5824; bugfix on 0.2.2.1-alpha.
|
||||
|
||||
o Minor bugfixes:
|
||||
- Avoid crashing on a malformed resolv.conf file when running a
|
||||
server using Libevent 1. Fixes bug 8788; bugfix on 0.1.1.23.
|
||||
|
||||
o Minor bugfixes (testing):
|
||||
- Improve the tinytest implementation of string operation tests
|
||||
so that comparisons NULL strings no longer crash the tests;
|
||||
they now just fail, normally. Fixes bug 9004; bugfix on
|
||||
0.2.2.4-alpha.
|
||||
|
||||
o Minor bugfixes:
|
||||
- Fix a comment about the rend_server_descriptor_t.protocols field
|
||||
to more accurately describe its range. Also, make that
|
||||
field unsigned, to more accurately reflect its usage.
|
||||
Fixes bug 9099; bugfix on 0.2.1.5-alpha.
|
||||
|
||||
o Documentation:
|
||||
- Document in the manpage that "KBytes" may also be written as
|
||||
"kilobytes" or "KB", that "Kbits" may also be written as
|
||||
"kilobits", and so forth. Closes ticket #9222.
|
||||
|
||||
o Minor bugfixes:
|
||||
- Give the correct URL in the warning message that we present
|
||||
when the user is trying to run a Tor relay on an ancient version
|
||||
of Windows. Fixes bug 9393.
|
||||
|
||||
o Minor bugfixes:
|
||||
- Non-exit servers no longer launch mock DNS requests to check for
|
||||
DNS hijacking. This has been unnecessary since 0.2.1.7-alpha,
|
||||
when non-exit servers stopped servicing DNS requests. Fixes bug
|
||||
965; bugfix on 0.2.1.7-alpha. Patch from Matt Pagan.
|
||||
|
||||
o Minor changes:
|
||||
- Decrease the lower limit of MaxMemInQueues to 256 MBytes, to
|
||||
appease raspberry pi users. Fixes bug 9686.
|
||||
|
||||
o Minor features:
|
||||
- Avoid hash-flooding denial-of-service attacks by using the secure
|
||||
SipHash-2-4 hash function for our hashtables. Without this
|
||||
feature, an attacker could degrade performance of a targeted
|
||||
client or server by flooding their data structures with a large
|
||||
number of data entries all calculated to be stored at the same
|
||||
hash table position, thereby degrading hash table
|
||||
performance. With this feature, hash table positions are derived
|
||||
from a randomized cryptographic key using SipHash-2-4, and an
|
||||
attacker cannot predict which entries will collide.
|
||||
Closes ticket 4900.
|
||||
|
||||
o Minor features:
|
||||
- Update geoip6 to the February 7 2014 Maxmind GeoLite2 Country
|
||||
database.
|
||||
o Minor features:
|
||||
- Update to the February 7 2014 Maxmind GeoLite2 Country database.
|
||||
|
||||
o Minor features:
|
||||
- Fix our version of the February 7 2014 Maxmind GeoLite2 Country database.
|
||||
|
||||
o Minor bugfixes (compilation):
|
||||
- Fix a 64-to-32-conversion warning in format_number_sigsafe().
|
||||
Bugfix on 0.2.5.2-alpha; patch from Nick Hopper.
|
||||
|
||||
o Code simplifications and refactoring:
|
||||
- Get rid of router->address, since in all cases it was just the
|
||||
string representation of router->addr. Resolves ticket 5528.
|
||||
|
||||
o Minor features:
|
||||
- Made PREDICTED_CIRCS_RELEVANCE_TIME configurable from config
|
||||
file with a new option, PredictedPortsRelevanceTime. Implements
|
||||
ticket #9176. Patch by unixninja92.
|
||||
|
||||
o Testing:
|
||||
- Update to the latest version of tinytest.
