Changes in version 0.2.2.17-alpha - 2010-09-2?
|
||||
Changes in version 0.2.2.17-alpha - 2010-09-30
|
||||
o Major features:
|
||||
- Exit relays now try harder to block exit attempts from unknown
|
||||
relays, to make it harder for people to use them as one-hop proxies
|
||||
a la tortunnel. Controlled by the refuseunknownexits consensus
|
||||
parameter (currently enabled), or you can override it on your
|
||||
relay with the RefuseUnknownExits torrc option.
|
||||
|
||||
o Major bugfixes (0.2.1.x and earlier):
|
||||
- Fix a bug in bandwidth accounting that could make us use twice
|
||||
the intended bandwidth when our interval start changes due to
|
||||
daylight saving time. Now we tolerate skew in stored vs computed
|
||||
interval starts: if the start of the period changes by no more than
|
||||
50% of the period's duration, we remember bytes that we transferred
|
||||
in the old period. Fixes bug 1511; bugfix on 0.0.9pre5.
|
||||
- Always search the Windows system directory for system DLLs, and
|
||||
nowhere else. Bugfix on 0.1.1.23; fixes bug 1954.
|
||||
- When you're using bridges and your network goes away and your
|
||||
bridges get marked as down, recover when you attempt a new socks
|
||||
connection (if the network is back), rather than waiting up to an
|
||||
hour to try fetching new descriptors for your bridges. Bugfix on
|
||||
0.2.0.3-alpha; fixes bug 1981.
|
||||
|
||||
o Major bugfixes (on 0.2.2.x):
|
||||
- Fix compilation on Windows. Bugfix on 0.2.2.16-alpha; related to
|
||||
bug 1797.
|
||||
- Fix a segfault that could happen when operating a bridge relay with
|
||||
no GeoIP database set. Fixes bug 1964; bugfix on 0.2.2.15-alpha.
|
||||
- The consensus bandwidth-weights (used by clients to choose fast
|
||||
relays) entered an unexpected edge case in September where
|
||||
Exits were much scarcer than Guards, resulting in bad weight
|
||||
recommendations. Now we compute them using new constraints that
|
||||
should succeed in all cases. Also alter directory authorities to
|
||||
not include the bandwidth-weights line if they fail to produce
|
||||
valid values. Fixes bug 1952; bugfix on 0.2.2.10-alpha.
|
||||
- When weighting bridges during path selection, we used to trust
|
||||
the bandwidths they provided in their descriptor, only capping them
|
||||
at 10MB/s. This turned out to be problematic for two reasons:
|
||||
Bridges could claim to handle a lot more traffic then they
|
||||
actually would, thus making more clients pick them and have a
|
||||
pretty effective DoS attack. The other issue is that new bridges
|
||||
that might not have a good estimate for their bw capacity yet
|
||||
would not get used at all unless no other bridges are available
|
||||
to a client. Fixes bug 1912; bugfix on 0.2.2.7-alpha.
|
||||
|
||||
o Minor features:
|
||||
- When we run out of directory information such that we can't build
|
||||
circuits, but then get enough that we can build circuits, log when
|
||||
we actually construct a circuit, so the user has a better chance of
|
||||
knowing what's going on. Fixes bug 1362.
|
||||
- Be more generous with how much bandwidth we'd use up (with
|
||||
accounting enabled) before entering "soft hibernation". Previously,
|
||||
we'd refuse new connections and circuits once we'd used up 95% of
|
||||
our allotment. Now, we use up 95% of our allotment, AND make sure
|
||||
that we have no more than 500MB (or 3 hours of expected traffic,
|
||||
whichever is lower) remaining before we enter soft hibernation.
|
||||
- If we've configured EntryNodes and our network goes away and/or all
|
||||
our entrynodes get marked down, optimistically retry them all when
|
||||
a new socks application request appears. Fixes bug 1882.
|
||||
- Add some more defensive programming for architectures that can't
|
||||
handle unaligned integer accesses. We don't know of any actual bugs
|
||||
right now, but that's the best time to fix them. Fixes bug 1943.
|
||||
- Support line continuations in the torrc config file. If a line
|
||||
ends with a single backslash character, the newline is ignored, and
|
||||
the configuration value is treated as continuing on the next line.
|
||||
Resolves bug 1929.
|
||||
|
||||
o Minor bugfixes (on 0.2.1.x and earlier):
|
||||
- For bandwidth accounting, calculate our expected bandwidth rate
|
||||
based on the time during which we were active and not in
|
||||
soft-hibernation during the last interval. Previously, we were
|
||||
also considering the time spent in soft-hibernation. If this
|
||||
was a long time, we would wind up underestimating our bandwidth
|
||||
by a lot, and skewing our wakeup time towards the start of the
|
||||
accounting interval. Fixes bug 1789. Bugfix on 0.0.9pre5.
|
||||
|
||||
o Minor bugfixes (on the circuit build timeout feature, 0.2.2.x):
|
||||
- Ignore cannibalized circuits when recording circuit build times.
|
||||
This should provide for a minor performance improvement for hidden
|
||||
service users using 0.2.2.14-alpha, and should remove two spurious
|
||||
notice log messages. Bugfix on 0.2.2.14-alpha; fixes bug 1740.
|
||||
- Simplify the logic that causes us to decide if the network is
|
||||
unavailable for purposes of recording circuit build times. If we
|
||||
receive no cells whatsoever for the entire duration of a circuit's
|
||||
full measured lifetime, the network is probably down. Also ignore
|
||||
one-hop directory fetching circuit timeouts when calculating our
|
||||
circuit build times. These changes should hopefully reduce the
|
||||
cases where we see ridiculous circuit build timeouts for people
|
||||
with spotty wireless connections. Fixes part of bug 1772; bugfix
|
||||
on 0.2.2.2-alpha.
|
||||
- Prevent the circuit build timeout from becoming larger than
|
||||
the maximum build time we have ever seen. Also, prevent the time
|
||||
period for measurement circuits from becoming larger than twice that
|
||||
value. Fixes the other part of bug 1772; bugfix on 0.2.2.2-alpha.
|
||||
|
||||
o Minor bugfixes (other, 0.2.2.x):
|
||||
- Resume generating CIRC FAILED REASON=TIMEOUT control port messages,
|
||||
which were disabled by the circuit build timeout changes in
|
||||
0.2.2.14-alpha. Bugfix on 0.2.2.14-alpha; fixes bug 1739.
|
||||
- Make sure we don't warn about missing bandwidth weights when
|
||||
choosing bridges or other relays not in the consensus. Bugfix on
|
||||
0.2.2.10-alpha; fixes bug 1805.
|
||||
- In our logs, do not double-report signatures from unrecognized
|
||||
authorities both as "from unknown authority" and "not
|
||||
present". Fixes bug 1956, bugfix on 0.2.2.16-alpha.
