Tor 0.1.0.3-rc is out
This is the third release candidate for the 0.1.0.x series. We've made
some performance improvements, made it tolerate more clock skew, and
fixed a bunch more bugs.
Please report any bugs, either in the installers or in Tor operation, so
we can get it perfect for an actual release: http://bugs.noreply.org/tor
o Improvements on 0.1.0.2-rc:
- Client now retries when streams end early for 'hibernating' or
'resource limit' reasons, rather than failing them.
- More automated handling for dirserver operators:
- Automatically approve nodes running 0.1.0.2-rc or later,
now that the the reachability detection stuff is working.
- Now we allow two unverified servers with the same nickname
but different keys. But if a nickname is verified, only that
nickname+key are allowed.
- If you're an authdirserver connecting to an address:port,
and it's not the OR you were expecting, forget about that
descriptor. If he *was* the one you were expecting, then forget
about all other descriptors for that address:port.
- Allow servers to publish descriptors from 12 hours in the future.
Corollary: only whine about clock skew from the dirserver if
he's a trusted dirserver (since now even verified servers could
have quite wrong clocks).
- Adjust maximum skew and age for rendezvous descriptors: let skew
be 48 hours rather than 90 minutes.
- Efficiency improvements:
- Keep a big splay tree of (circid,orconn)->circuit mappings to make
it much faster to look up a circuit for each relay cell.
- Remove most calls to assert_all_pending_dns_resolves_ok(),
since they're eating our cpu on exit nodes.
- Stop wasting time doing a case insensitive comparison for every
dns name every time we do any lookup. Canonicalize the names to
lowercase and be done with it.
- Start sending 'truncated' cells back rather than destroy cells,
if the circuit closes in front of you. This means we won't have
to abandon partially built circuits.
- Only warn once per nickname from add_nickname_list_to_smartlist
per failure, so an entrynode or exitnode choice that's down won't
yell so much.
- Put a note in the torrc about abuse potential with the default
- Revise control spec and implementation to allow all log messages to
be sent to controller with their severities intact (suggested by
Matt Edman). Update TorControl to handle new log event types.
- Provide better explanation messages when controller's POSTDESCRIPTOR
- Stop putting nodename in the Platform string in server descriptors.
It doesn't actually help, and it is confusing/upsetting some people.
o Bugfixes on 0.1.0.2-rc:
- We were printing the host mask wrong in exit policies in server
descriptors. This isn't a critical bug though, since we were still
obeying the exit policy internally.
- Fix Tor when compiled with libevent but without pthreads: move
connection_unregister() from _connection_free() to
- Fix an assert trigger (already fixed in 0.0.9.x): when we have
the rare mysterious case of accepting a conn on 0.0.0.0:0, then
when we look through the connection array, we'll find any of the
cpu/dnsworkers. This is no good.
o Bugfixes on 0.0.9.x:
- Fix possible bug on threading platforms (e.g. win32) which was
leaking a file descriptor whenever a cpuworker or dnsworker died.
- When using preferred entry or exit nodes, ignore whether the
circuit wants uptime or capacity. They asked for the nodes, they
get the nodes.
- chdir() to your datadirectory at the *end* of the daemonize process,
not the beginning. This was a problem because the first time you
run tor, if your datadir isn't there, and you have runasdaemon set
to 1, it will try to chdir to it before it tries to create it. Oops.
- Handle changed router status correctly when dirserver reloads
fingerprint file. We used to be dropping all unverified descriptors
right then. The bug was hidden because we would immediately
fetch a directory from another dirserver, which would include the
descriptors we just dropped.
- When we're connecting to an OR and he's got a different nickname/key
than we were expecting, only complain loudly if we're an OP or a
dirserver. Complaining loudly to the OR admins just confuses them.
- Tie MAX_DIR_SIZE to MAX_BUF_SIZE, so now directory sizes won't get
artificially capped at 500kB.
