Changes in version 0.1.1.13-alpha - 2006-02-09
o Crashes in 0.1.1.x:
- When you tried to setconf ORPort via the controller, Tor would
crash. So people using TorCP to become a server were sad.
- Solve (I hope) the stack-smashing bug that we were seeing on fast
servers. The problem appears to be something do with OpenSSL's
random number generation, or how we call it, or something. Let me
know if the crashes continue.
- Turn crypto hardware acceleration off by default, until we find
somebody smart who can test it for us. (It appears to produce
seg faults in at least some cases.)
- Fix a rare assert error when we've tried all intro points for
a hidden service and we try fetching the service descriptor again:
"Assertion conn->state != AP_CONN_STATE_RENDDESC_WAIT failed"
o Major fixes:
- Fix a major load balance bug: we were round-robining in 16 KB
chunks, and servers with bandwidthrate of 20 KB, while downloading
a 600 KB directory, would starve their other connections. Now we
try to be a bit more fair.
- Dir authorities and mirrors were never expiring the newest
descriptor for each server, causing memory and directory bloat.
- Fix memory-bloating and connection-bloating bug on servers: We
were never closing any connection that had ever had a circuit on
it, because we were checking conn->n_circuits == 0, yet we had a
bug that let it go negative.
- Make Tor work using squid as your http proxy again -- squid returns
an error if you ask for a URL that's too long, and it uses a really
generic error message. Plus, many people are behind a transparent
squid so they don't even realize it.
- On platforms that don't have getrlimit (like Windows), we were
artificially constraining ourselves to a max of 1024
connections. Now just assume that we can handle as many as 15000
connections. Hopefully this won't cause other problems.
- Add a new config option ExitPolicyRejectPrivate which defaults to 1.
This means all exit policies will begin with rejecting private
addresses, unless the server operator explicitly turns it off.
o Major features:
- Clients not longer download descriptors for non-running descriptors.
- Before we add new directory authorities, we should make it
clear that only v1 authorities should receive/publish hidden
service descriptors.
o Minor features:
- As soon as we've fetched some more directory info, immediately
try to download more server descriptors. This way we don't have
a 10 second pause during initial bootstrapping.
- Remove even more loud log messages that the server operator can't
do anything about.
- When we're running an obsolete or un-recommended version, make
the log message more clear about what the problem is and what
versions *are* still recommended.
- Provide a more useful warn message when our onion queue gets full:
the CPU is too slow or the exit policy is too liberal.
- Don't warn when we receive a 503 from a dirserver/cache -- this will
pave the way for them being able to refuse if they're busy.
- When we fail to bind a listener, try to provide a more useful
log message: e.g., "Is Tor already running?"
- Adjust tor-spec to parameterize cell and key lengths. Now Ian
Goldberg can prove things about our handshake protocol more easily.
- MaxConn has been obsolete for a while now. Document the ConnLimit
config option, which is a *minimum* number of file descriptors
that must be available else Tor refuses to start.
- Apply Matt Ghali's --with-syslog-facility patch to ./configure
if you log to syslog and want something other than LOG_DAEMON.
- Make dirservers generate a separate "guard" flag to mean,
"would make a good entry guard". Make clients parse it and vote
on it. Not used by clients yet.
- Implement --with-libevent-dir option to ./configure. Also, improve
search techniques to find libevent, and use those for openssl too.
- Bump the default bandwidthrate to 3 MB, and burst to 6 MB
- Only start testing reachability once we've established a
circuit. This will make startup on dirservers less noisy.
- Don't try to upload hidden service descriptors until we have
established a circuit.
- Fix the controller's "attachstream 0" command to treat conn like it
just connected, doing address remapping, handling .exit and .onion
idioms, and so on. Now we're more uniform in making sure that the
controller hears about new and closing connections.

o Bugfixes on 0.1.1.x:
- The fix to close duplicate server connections was closing all
