Changes in version 0.2.4.12-alpha - 2013-04-18
o Major features:
- Raise the default time that a client keeps an entry guard from
"1-2 months" to "2-3 months", as suggested by Tariq Elahi's WPES
2012 paper. (We would make it even longer, but we need better client
load balancing first.) Also, make the guard lifetime controllable
via a new GuardLifetime torrc option and a GuardLifetime consensus
parameter. Start of a fix for bug 8240; bugfix on 0.1.1.11-alpha.
- Directory authorities now prefer using measured bandwidths to
advertised ones when computing flags and thresholds. Resolves
ticket 8273.
- Directory authorities that have more than a threshold number
of relays with measured bandwidths now treat relays with unmeasured
bandwidths as having bandwidth 0. Resolves ticket 8435.
o Major bugfixes (assert / resource use):
- Avoid a bug where our response to TLS renegotation under certain
network conditions could lead to a busy-loop, with 100% CPU
consumption. Fixes bug 5650; bugfix on 0.2.0.16-alpha.
- Avoid an assertion when we discover that we'd like to write a cell
onto a closing connection: just discard the cell. Fixes another
case of bug 7350; bugfix on 0.2.4.4-alpha.
o Major bugfixes (client-side privacy):
- When we mark a circuit as unusable for new circuits, have it
continue to be unusable for new circuits even if MaxCircuitDirtiness
is increased too much at the wrong time, or the system clock jumps
backwards. Fixes bug 6174; bugfix on 0.0.2pre26.
- If ClientDNSRejectInternalAddresses ("do not believe DNS queries
which have resolved to internal addresses") is set, apply that
rule to IPv6 as well. Fixes bug 8475; bugfix on 0.2.0.7-alpha.
- When an exit relay rejects a stream with reason "exit policy", but
we only know an exit policy summary (e.g. from the microdesc
consensus) for it, do not mark the relay as useless for all exiting.
Instead, mark just the circuit as unsuitable for that particular
address. Fixes part of bug 7582; bugfix on 0.2.3.2-alpha.
- Allow applications to get proper stream isolation with
IsolateSOCKSAuth. Many SOCKS5 clients that want to offer
username/password authentication also offer "no authentication". Tor
had previously preferred "no authentication", so the applications
never actually sent Tor their auth details. Now Tor selects
username/password authentication if it's offered. You can disable
this behavior on a per-SOCKSPort basis via PreferSOCKSNoAuth. Fixes
bug 8117; bugfix on 0.2.3.3-alpha.
o Major bugfixes (other):
- When unable to find any working directory nodes to use as a
directory guard, give up rather than adding the same non-working
nodes to the directory guard list over and over. Fixes bug 8231;
bugfix on 0.2.4.8-alpha.
o Minor features:
- Reject as invalid most directory objects containing a NUL.
Belt-and-suspender fix for bug 8037.
- In our testsuite, create temporary directories with a bit more
entropy in their name to make name collisions less likely. Fixes
bug 8638.
- Add CACHED keyword to ADDRMAP events in the control protocol
to indicate whether a DNS result will be cached or not. Resolves
ticket 8596.
- Eliminate several instances where we use "Nickname=ID" to refer to
nodes in logs. Use "Nickname (ID)" instead. (Elsewhere, we still use
"$ID=Nickname", which is also acceptable.) Fixes bug 7065. Bugfix
on 0.2.3.21-rc, 0.2.4.5-alpha, 0.2.4.8-alpha, and 0.2.4.10-alpha.
- Update to the April 3 2013 Maxmind GeoLite Country database.
o Minor features (build):
- Detect and reject attempts to build Tor with threading support
when OpenSSL has been compiled without threading support.
Fixes bug 6673.
- Clarify that when autoconf is checking for nacl, it is checking
specifically for nacl with a fast curve25519 implementation.
Fixes bug 8014.
- Warn if building on a platform with an unsigned time_t: there
are too many places where Tor currently assumes that time_t can
hold negative values. We'd like to fix them all, but probably
some will remain.
o Minor bugfixes (build):
- Fix compilation warning with some versions of clang that would
prefer the -Wswitch-enum compiler flag to warn about switch
statements with missing enum values, even if those switch
statements have a "default:" statement. Fixes bug 8598; bugfix
on 0.2.4.10-alpha.
- Build Tor correctly on 32-bit platforms where the compiler can build
but not run code using the "uint128_t" construction. Fixes bug 8587;
bugfix on 0.2.4.8-alpha.
- Add the old src/or/micro-revision.i filename to CLEANFILES.
On the off chance that somebody has one, it will go away as soon
as they run "make clean". Fix for bug 7143; bugfix on 0.2.4.1-alpha.
- Fix some bugs in tor-fw-helper-natpmp when trying to build and
run it on Windows. More bugs likely remain. Patch from Gisle Vanem.
Fixes bug 7280; bugfix on 0.2.3.1-alpha.
o Minor bugfixes (protocol):
- Fix the handling of a TRUNCATE cell when it arrives while the
circuit extension is in progress. Fixes bug 7947; bugfix on 0.0.7.1.
- Fix a misframing issue when reading the version numbers in a
VERSIONS cell. Previously we would recognize [00 01 00 02] as
'version 1, version 2, and version 0x100', when it should have
only included versions 1 and 2. Fixes bug 8059; bugfix on
0.2.0.10-alpha. Reported pseudonymously.
- Make the format and order of STREAM events for DNS lookups
consistent among the various ways to launch DNS lookups. Fixes
bug 8203; bugfix on 0.2.0.24-rc. Patch by "Desoxy."
- Correct our check for which versions of Tor support the EXTEND2
cell. We had been willing to send it to Tor 0.2.4.7-alpha and
later, when support was really added in version 0.2.4.8-alpha.
Fixes bug 8464; bugfix on 0.2.4.8-alpha.
o Minor bugfixes (correctness):
- Correctly store microdescriptors and extrainfo descriptors with
an internal NUL byte. Fixes bug 8037; bugfix on 0.2.0.1-alpha.
Bug reported by "cypherpunks".
- Increase the width of the field used to remember a connection's
link protocol version to two bytes. Harmless for now, since the
only currently recognized versions are one byte long. Reported
pseudonymously. Fixes bug 8062; bugfix on 0.2.0.10-alpha.
- If the state file's path bias counts are invalid (presumably from a
buggy Tor prior to 0.2.4.10-alpha), make them correct. Also add
additional checks and log messages to the scaling of Path Bias
counts, in case there still are remaining issues with scaling.
Should help resolve bug 8235.
o Minor bugfixes (syscalls):
- Always check the return values of functions fcntl() and
setsockopt(). We don't believe these are ever actually failing in
practice, but better safe than sorry. Also, checking these return
values should please analysis tools like Coverity. Patch from
'flupzor'. Fixes bug 8206; bugfix on all versions of Tor.
- Use direct writes rather than stdio when building microdescriptor
caches, in an attempt to mitigate bug 8031, or at least make it
less common.
o Minor bugfixes (config):
- When rejecting a configuration because we were unable to parse a
quoted string, log an actual error message. Fix for bug 7950;
bugfix on 0.2.0.16-alpha.
- Behave correctly when the user disables LearnCircuitBuildTimeout
but doesn't tell us what they would like the timeout to be. Fixes
bug 6304; bugfix on 0.2.2.14-alpha.
- When autodetecting the number of CPUs, use the number of available
CPUs in preference to the number of configured CPUs. Inform the
user if this reduces the number of available CPUs. Fixes bug 8002.
Bugfix on 0.2.3.1-alpha.
- Elevate the severity of the warning message when setting
EntryNodes but disabling UseGuardNodes to an error. The outcome
of letting Tor proceed with those options enabled (which causes
EntryNodes to get ignored) is sufficiently different from what
was expected that it's best to just refuse to proceed. Fixes bug
8180; bugfix on 0.2.3.11-alpha.
- Allow TestingTorNetworks to override the 4096-byte minimum for
the Fast threshold. Otherwise they can't bootstrap until they've
observed more traffic. Fixes bug 8508; bugfix on 0.2.4.10-alpha.
- Fix some logic errors when the user manually overrides the
PathsNeededToBuildCircuits option in torrc. Fixes bug 8599; bugfix
on 0.2.4.10-alpha.
o Minor bugfixes (log messages to help diagnose bugs):
- If we fail to free a microdescriptor because of bug 7164, log
the filename and line number from which we tried to free it.
This should help us finally fix bug 7164.
- Add another diagnostic to the heartbeat message: track and log
overhead that TLS is adding to the data we write. If this is
high, we are sending too little data to SSL_write at a time.
Diagnostic for bug 7707.
- Add more detail to a log message about relaxed timeouts. Hopefully
this additional detail will allow us to diagnose the cause of
bug 7799.
- Warn more aggressively when flushing microdescriptors to a
microdescriptor cache fails, in an attempt to mitigate bug 8031,
or at least make it more diagnosable.
- Improve debugging output to attempt to diagnose the underlying
cause of bug 8185.
- Log the purpose of a path-bias testing circuit correctly.
Improves a log message from bug 8477; bugfix on 0.2.4.8-alpha.
o Minor bugfixes (0.2.4.x log messages that were too noisy):
- Use circuit creation time for network liveness evaluation. This
should eliminate warning log messages about liveness caused
by changes in timeout evaluation. Fixes bug 6572; bugfix on
0.2.4.8-alpha.
- Reduce a path bias length check notice log to info. The notice
is triggered when creating controller circuits. Fixes bug 8196;
bugfix on 0.2.4.8-alpha.
- Fix a path state issue that triggered a notice during relay startup.
Fixes bug 8320; bugfix on 0.2.4.10-alpha.
- Reduce occurrences of warns about circuit purpose in
connection_ap_expire_building(). Fixes bug 8477; bugfix on
0.2.4.11-alpha.
o Minor bugfixes (pre-0.2.4.x log messages that were too noisy):
- If we encounter a write failure on a SOCKS connection before we
finish our SOCKS handshake, don't warn that we closed the
connection before we could send a SOCKS reply. Fixes bug 8427;
bugfix on 0.1.0.1-rc.
- Correctly recognize that [::1] is a loopback address. Fixes
bug 8377; bugfix on 0.2.1.3-alpha.
- Fix a directory authority warn caused when we have a large amount
of badexit bandwidth. Fixes bug 8419; bugfix on 0.2.2.10-alpha.
- Don't attempt to relax the timeout of already opened 1-hop circuits.
They might never timeout. This should eliminate some/all cases of
the relaxed timeout log message.
- Don't log inappropriate heartbeat messages when hibernating: a
hibernating node is _expected_ to drop out of the consensus,
decide it isn't bootstrapped, and so forth. Fixes bug
7302; bugfix on 0.2.3.1-alpha.
- Don't complain about bootstrapping problems while hibernating.
These complaints reflect a general code problem, but not one
with any problematic effects. (No connections are actually
opened.) Fixes part of bug 7302; bugfix on 0.2.3.2-alpha.
o Documentation fixes:
- Update tor-fw-helper.1.txt and tor-fw-helper.c to make option
names match. Fixes bug 7768.
- Make the torify manpage no longer refer to tsocks; torify hasn't
supported tsocks since 0.2.3.14-alpha.
- Make the tor manpage no longer reference tsocks.
- Fix the GeoIPExcludeUnknown documentation to refer to
ExcludeExitNodes rather than the currently nonexistent
ExcludeEntryNodes. Spotted by "hamahangi" on tor-talk.
o Removed files:
- The tor-tsocks.conf is no longer distributed or installed. We
recommend that tsocks users use torsocks instead. Resolves
ticket 8290.
