1 Changes in version 0.1.1.6-alpha - 2005-09-08
2 o Fixes on 0.1.1.5-alpha:
3 - We broke fascistfirewall in 0.1.1.5-alpha. Oops.
4 - Fix segfault in unit tests in 0.1.1.5-alpha. Oops.
5 - Fix bug with tor_memmem finding a match at the end of the string.
6 - Make unit tests run without segfaulting.
7 - Resolve some solaris x86 compile warnings.
8 - Handle duplicate lines in approved-routers files without warning.
10 o New controller features/fixes:
11 - Add a "RESETCONF" command so you can set config options like
12 AllowUnverifiedNodes and LongLivedPorts to "". Also, if you give
13 a config option in the torrc with no value, then it clears it
14 entirely (rather than setting it to its default).
15 - Add a "GETINFO config-file" to tell us where torrc is.
16 - Avoid sending blank lines when GETINFO replies should be empty.
17 - Add a QUIT command for the controller (for using it manually).
19 o Start on the new directory design:
20 - Generate, publish, cache, serve new network-status format.
21 - Publish individual descriptors (by fingerprint, by "all", and by
23 - Publish client and server recommended versions separately.
24 - Allow tor_gzip_uncompress() to handle multiple concatenated
25 compressed strings. Serve compressed groups of router
26 descriptors. The compression logic here could be more
28 - Distinguish v1 authorities (all currently trusted directories)
29 from v2 authorities (all trusted directories).
30 - Change DirServers config line to note which dirs are v1 authorities.
31 - Add configuration option "V1AuthoritativeDirectory 1" which
32 moria1, moria2, and tor26 should set.
33 - Remove option when getting directory cache to see whether they
34 support running-routers; they all do now. Replace it with one
35 to see whether caches support v2 stuff.
38 - Dirservers now do their own external reachability testing of each
39 Tor server, and only list them as running if they've been found to
40 be reachable. We also send back warnings to the server's logs if
41 it uploads a descriptor that we already believe is unreachable.
42 - Implement exit enclaves: if we know an IP address for the
43 destination, and there's a running Tor server at that address
44 which allows exit to the destination, then extend the circuit to
45 that exit first. This provides end-to-end encryption and end-to-end
46 authentication. Also, if the user asks for a .exit node, cannibalize
47 a general circ for it so it's faster.
48 - Permit transitioning from ORPort=0 to ORPort!=0, and back, from the
49 controller. Also, rotate dns and cpu workers if the controller
50 changes options that will affect them; and initialize the dns
51 worker cache tree whether or not we start out as a server.
52 - Only upload a new server descriptor when options change, 18
53 hours have passed, uptime is reset, or bandwidth changes a lot.
54 - Check [X-]Forwarded-For headers in HTTP requests when generating
55 log messages. This lets people run dirservers (and caches) behind
56 Apache but still know which IP addresses are causing warnings.
58 o Config option changes:
59 - Replace (Fascist)Firewall* config options with a new
60 ReachableAddresses option that understands address policies.
61 For example, "ReachableAddresses *:80,*:443"
62 - Get rid of IgnoreVersion undocumented config option, and make us
63 only warn, never exit, when we're running an obsolete version.
64 - Make MonthlyAccountingStart config option truly obsolete now.
67 - It turns out we couldn't bootstrap a network since we added
68 reachability detection. Good thing the Tor network has never gone
69 down. Add an AssumeReachable config option to let servers and
70 dirservers bootstrap. When we're trying to build a high-uptime or
71 high-bandwidth circuit but there aren't enough suitable servers,
72 try being less picky rather than simply failing.
73 - Our logic to decide if the OR we connected to was the right guy
74 was brittle and maybe open to a mitm for unverified routers.
75 - We weren't cannibalizing circuits correctly for
76 CIRCUIT_PURPOSE_C_ESTABLISH_REND and
77 CIRCUIT_PURPOSE_S_ESTABLISH_INTRO, so we were being forced to
78 build those from scratch. This should make hidden services faster.
79 - Predict required circuits better, with an eye toward making hidden
80 services faster on the service end.
81 - Retry streams if the exit node sends back a 'misc' failure. This
82 should result in fewer random failures. Also, after failing
83 from resolve failed or misc, reset the num failures, so we give
84 it a fair shake next time we try.
85 - When we're shutting down and we do something like try to post a
86 server descriptor or rendezvous descriptor, don't complain that
87 we seem to be unreachable. Of course we are, we're shutting down.
88 - Add TTLs to RESOLVED, CONNECTED, and END_REASON_EXITPOLICY cells.
89 We don't use them yet, but maybe one day our DNS resolver will be
90 able to discover them.
91 - Make ContactInfo mandatory for authoritative directory servers.
92 - Require server descriptors to list IPv4 addresses -- hostnames
93 are no longer allowed. This also fixes some potential security
94 problems with people providing hostnames as their address and then
95 preferentially resolving them to partition users.
96 - Change log line for unreachability to explicitly suggest /etc/hosts
97 as the culprit. Also make it clearer what IP address and ports we're
98 testing for reachability.
99 - Put quotes around user-supplied strings when logging so users are
100 more likely to realize if they add bad characters (like quotes)
102 - Let auth dir servers start without specifying an Address config
104 - Make unit tests (and other invocations that aren't the real Tor)
105 run without launching listeners, creating subdirectories, and so on.
108 Changes in version 0.1.1.5-alpha - 2005-08-08
109 o Bugfixes included in 0.1.0.14.
111 o Bugfixes on 0.1.0.x:
112 - If you write "HiddenServicePort 6667 127.0.0.1 6668" in your
113 torrc rather than "HiddenServicePort 6667 127.0.0.1:6668",
114 it would silently using ignore the 6668.
117 Changes in version 0.1.1.4-alpha - 2005-08-04
118 o Bugfixes included in 0.1.0.13.
121 - Improve tor_gettimeofday() granularity on windows.
122 - Make clients regenerate their keys when their IP address changes.
123 - Implement some more GETINFO goodness: expose helper nodes, config
124 options, getinfo keys.
127 Changes in version 0.1.1.3-alpha - 2005-07-25
128 o Bugfixes on 0.1.1.2-alpha:
129 - Fix a bug in handling the controller's "post descriptor"
131 - Fix several bugs in handling the controller's "extend circuit"
133 - Fix a bug in handling the controller's "stream status" event.
134 - Fix an assert failure if we have a controller listening for
135 circuit events and we go offline.
136 - Re-allow hidden service descriptors to publish 0 intro points.
137 - Fix a crash when generating your hidden service descriptor if
138 you don't have enough intro points already.
140 o New features on 0.1.1.2-alpha:
141 - New controller function "getinfo accounting", to ask how
142 many bytes we've used in this time period.
143 - Experimental support for helper nodes: a lot of the risk from
144 a small static adversary comes because users pick new random
145 nodes every time they rebuild a circuit. Now users will try to
146 stick to the same small set of entry nodes if they can. Not
147 enabled by default yet.
149 o Bugfixes on 0.1.0.12:
150 - If you're an auth dir server, always publish your dirport,
151 even if you haven't yet found yourself to be reachable.
152 - Fix a size_t underflow in smartlist_join_strings2() that made
153 it do bad things when you hand it an empty smartlist.
156 Changes in version 0.1.1.2-alpha - 2005-07-14
157 o New directory servers:
158 - tor26 has changed IP address.
160 o Bugfixes on 0.1.0.x, crashes/leaks:
161 - Port the servers-not-obeying-their-exit-policies fix from 0.1.0.11.
162 - Fix an fd leak in start_daemon().
163 - On Windows, you can't always reopen a port right after you've
164 closed it. So change retry_listeners() to only close and re-open
165 ports that have changed.
166 - Fix a possible double-free in tor_gzip_uncompress().
168 o Bugfixes on 0.1.0.x, usability:
169 - When tor_socketpair() fails in Windows, give a reasonable
170 Windows-style errno back.
171 - Let people type "tor --install" as well as "tor -install" when they
172 want to make it an NT service.
173 - NT service patch from Matt Edman to improve error messages.
174 - When the controller asks for a config option with an abbreviated
175 name, give the full name in our response.
176 - Correct the man page entry on TrackHostExitsExpire.
177 - Looks like we were never delivering deflated (i.e. compressed)
178 running-routers lists, even when asked. Oops.
179 - When --disable-threads is set, do not search for or link against
182 o Bugfixes on 0.1.1.x:
183 - Fix a seg fault with autodetecting which controller version is
187 - New hidden service descriptor format: put a version in it, and
188 let people specify introduction/rendezvous points that aren't
189 in "the directory" (which is subjective anyway).
190 - Allow the DEBUG controller event to work again. Mark certain log
191 entries as "don't tell this to controllers", so we avoid cycles.
194 Changes in version 0.1.1.1-alpha - 2005-06-29
196 - Make OS X init script check for missing argument, so we don't
197 confuse users who invoke it incorrectly.
198 - Fix a seg fault in "tor --hash-password foo".
199 - Fix a possible way to DoS dirservers.
200 - When we complain that your exit policy implicitly allows local or
201 private address spaces, name them explicitly so operators can
203 - Make the log message less scary when all the dirservers are
204 temporarily unreachable.
205 - We were printing the number of idle dns workers incorrectly when
209 - Revised controller protocol (version 1) that uses ascii rather
210 than binary. Add supporting libraries in python and java so you
211 can use the controller from your applications without caring how
213 - Spiffy new support for crypto hardware accelerators. Can somebody
217 Changes in version 0.1.0.14 - 2005-08-08
218 o Bugfixes on 0.1.0.x:
219 - Fix the other half of the bug with crypto handshakes.
220 - Fix an assert trigger if you send a 'signal term' via the
221 controller when it's listening for 'event info' messages.
224 Changes in version 0.1.0.13 - 2005-08-04
225 o Bugfixes on 0.1.0.x:
226 - Fix a critical bug in the security of our crypto handshakes.
227 - Fix a size_t underflow in smartlist_join_strings2() that made
228 it do bad things when you hand it an empty smartlist.
229 - Fix Windows installer to ship Tor license (thanks to Aphex for
230 pointing out this oversight) and put a link to the doc directory
232 - Explicitly set no-unaligned-access for sparc: it turns out the
233 new gcc's let you compile broken code, but that doesn't make it
237 Changes in version 0.1.0.12 - 2005-07-18
238 o New directory servers:
239 - tor26 has changed IP address.
241 o Bugfixes on 0.1.0.x:
242 - Fix a possible double-free in tor_gzip_uncompress().
243 - When --disable-threads is set, do not search for or link against
245 - Don't trigger an assert if an authoritative directory server
246 claims its dirport is 0.
247 - Fix bug with removing Tor as an NT service: some people were
248 getting "The service did not return an error." Thanks to Matt
252 Changes in version 0.1.0.11 - 2005-06-30
253 o Bugfixes on 0.1.0.x:
254 - Fix major security bug: servers were disregarding their
255 exit policies if clients behaved unexpectedly.
256 - Make OS X init script check for missing argument, so we don't
257 confuse users who invoke it incorrectly.
258 - Fix a seg fault in "tor --hash-password foo".
259 - The MAPADDRESS control command was broken.
262 Changes in version 0.1.0.10 - 2005-06-14
264 - Make NT services work and start on startup on Win32 (based on
265 patch by Matt Edman). See the FAQ entry for details.
266 - Make 'platform' string in descriptor more accurate for Win32
267 servers, so it's not just "unknown platform".
268 - REUSEADDR on normal platforms means you can rebind to the port
269 right after somebody else has let it go. But REUSEADDR on Win32
270 means you can bind to the port _even when somebody else already
271 has it bound_! So, don't do that on Win32.
272 - Clean up the log messages when starting on Win32 with no config
274 - Allow seeding the RNG on Win32 even when you're not running as
275 Administrator. If seeding the RNG on Win32 fails, quit.
277 o Assert / crash bugs:
278 - Refuse relay cells that claim to have a length larger than the
279 maximum allowed. This prevents a potential attack that could read
280 arbitrary memory (e.g. keys) from an exit server's process.
281 - If unofficial Tor clients connect and send weird TLS certs, our
282 Tor server triggers an assert. Stop asserting, and start handling
283 TLS errors better in other situations too.
284 - Fix a race condition that can trigger an assert when we have a
285 pending create cell and an OR connection attempt fails.
288 - Use pthreads for worker processes rather than forking. This was
289 forced because when we forked, we ended up wasting a lot of
290 duplicate ram over time.
291 - Also switch to foo_r versions of some library calls to allow
292 reentry and threadsafeness.
293 - Implement --disable-threads configure option. Disable threads on
294 netbsd and openbsd by default, because they have no reentrant
295 resolver functions (!), and on solaris since it has other
297 - Fix possible bug on threading platforms (e.g. win32) which was
298 leaking a file descriptor whenever a cpuworker or dnsworker died.
299 - Fix a minor memory leak when somebody establishes an introduction
300 point at your Tor server.
301 - Fix possible memory leak in tor_lookup_hostname(). (Thanks to
303 - Add ./configure --with-dmalloc option, to track memory leaks.
304 - And try to free all memory on closing, so we can detect what
307 o Protocol correctness:
308 - When we've connected to an OR and handshaked but didn't like
309 the result, we were closing the conn without sending destroy
310 cells back for pending circuits. Now send those destroys.
311 - Start sending 'truncated' cells back rather than destroy cells
312 if the circuit closes in front of you. This means we won't have
313 to abandon partially built circuits.
314 - Handle changed router status correctly when dirserver reloads
315 fingerprint file. We used to be dropping all unverified descriptors
316 right then. The bug was hidden because we would immediately
317 fetch a directory from another dirserver, which would include the
318 descriptors we just dropped.
319 - Revise tor-spec to add more/better stream end reasons.
320 - Revise all calls to connection_edge_end to avoid sending 'misc',
321 and to take errno into account where possible.
322 - Client now retries when streams end early for 'hibernating' or
323 'resource limit' reasons, rather than failing them.
324 - Try to be more zealous about calling connection_edge_end when
325 things go bad with edge conns in connection.c.
327 o Robustness improvements:
328 - Better handling for heterogeneous / unreliable nodes:
329 - Annotate circuits with whether they aim to contain high uptime
330 nodes and/or high capacity nodes. When building circuits, choose
332 - This means that every single node in an intro rend circuit,
333 not just the last one, will have a minimum uptime.
334 - New config option LongLivedPorts to indicate application streams
335 that will want high uptime circuits.
336 - Servers reset uptime when a dir fetch entirely fails. This
337 hopefully reflects stability of the server's network connectivity.
338 - If somebody starts his tor server in Jan 2004 and then fixes his
339 clock, don't make his published uptime be a year.
340 - Reset published uptime when we wake up from hibernation.
341 - Introduce a notion of 'internal' circs, which are chosen without
342 regard to the exit policy of the last hop. Intro and rendezvous
343 circs must be internal circs, to avoid leaking information. Resolve
344 and connect streams can use internal circs if they want.
345 - New circuit pooling algorithm: keep track of what destination ports
346 we've used recently (start out assuming we'll want to use 80), and
347 make sure to have enough circs around to satisfy these ports. Also
348 make sure to have 2 internal circs around if we've required internal
349 circs lately (and with high uptime if we've seen that lately too).
350 - Turn addr_policy_compare from a tristate to a quadstate; this should
351 help address our "Ah, you allow 1.2.3.4:80. You are a good choice
352 for google.com" problem.
353 - When a client asks us for a dir mirror and we don't have one,
354 launch an attempt to get a fresh one.
355 - First cut at support for "create-fast" cells. Clients can use
356 these when extending to their first hop, since the TLS already
357 provides forward secrecy and authentication. Not enabled on
360 o Reachability testing.
361 - Your Tor server will automatically try to see if its ORPort and
362 DirPort are reachable from the outside, and it won't upload its
363 descriptor until it decides at least ORPort is reachable (when
364 DirPort is not yet found reachable, publish it as zero).
365 - When building testing circs for ORPort testing, use only
366 high-bandwidth nodes, so fewer circuits fail.
367 - Notice when our IP changes, and reset stats/uptime/reachability.
368 - Authdirservers don't do ORPort reachability detection, since
369 they're in clique mode, so it will be rare to find a server not
370 already connected to them.
371 - Authdirservers now automatically approve nodes running 0.1.0.2-rc
375 - Now we allow two unverified servers with the same nickname
376 but different keys. But if a nickname is verified, only that
377 nickname+key are allowed.
378 - If you're an authdirserver connecting to an address:port,
379 and it's not the OR you were expecting, forget about that
380 descriptor. If he *was* the one you were expecting, then forget
381 about all other descriptors for that address:port.
382 - Allow servers to publish descriptors from 12 hours in the future.
383 Corollary: only whine about clock skew from the dirserver if
384 he's a trusted dirserver (since now even verified servers could
385 have quite wrong clocks).
386 - Require servers that use the default dirservers to have public IP
387 addresses. We have too many servers that are configured with private
388 IPs and their admins never notice the log entries complaining that
389 their descriptors are being rejected.
391 o Efficiency improvements:
392 - Use libevent. Now we can use faster async cores (like epoll, kpoll,
393 and /dev/poll), and hopefully work better on Windows too.
394 - Apple's OS X 10.4.0 ships with a broken kqueue API, and using
395 kqueue on 10.3.9 causes kernel panics. Don't use kqueue on OS X.
396 - Find libevent even if it's hiding in /usr/local/ and your
397 CFLAGS and LDFLAGS don't tell you to look there.
398 - Be able to link with libevent as a shared library (the default
399 after 1.0d), even if it's hiding in /usr/local/lib and even
400 if you haven't added /usr/local/lib to your /etc/ld.so.conf,
401 assuming you're running gcc. Otherwise fail and give a useful
403 - Switch to a new buffer management algorithm, which tries to avoid
404 reallocing and copying quite as much. In first tests it looks like
405 it uses *more* memory on average, but less cpu.
406 - Switch our internal buffers implementation to use a ring buffer,
407 to hopefully improve performance for fast servers a lot.
408 - Reenable the part of the code that tries to flush as soon as an
409 OR outbuf has a full TLS record available. Perhaps this will make
410 OR outbufs not grow as huge except in rare cases, thus saving lots
411 of CPU time plus memory.
412 - Improve performance for dirservers: stop re-parsing the whole
413 directory every time you regenerate it.
414 - Keep a big splay tree of (circid,orconn)->circuit mappings to make
415 it much faster to look up a circuit for each relay cell.
416 - Remove most calls to assert_all_pending_dns_resolves_ok(),
417 since they're eating our cpu on exit nodes.
418 - Stop wasting time doing a case insensitive comparison for every
419 dns name every time we do any lookup. Canonicalize the names to
420 lowercase when you first see them.
423 - Handle unavailable hidden services better. Handle slow or busy
424 hidden services better.
425 - Cannibalize GENERAL circs to be C_REND, C_INTRO, S_INTRO, and S_REND
426 circ as necessary, if there are any completed ones lying around
427 when we try to launch one.
428 - Make hidden services try to establish a rendezvous for 30 seconds
429 after fetching the descriptor, rather than for n (where n=3)
430 attempts to build a circuit.
431 - Adjust maximum skew and age for rendezvous descriptors: let skew
432 be 48 hours rather than 90 minutes.
433 - Reject malformed .onion addresses rather then passing them on as
437 - More Tor controller support. See
438 http://tor.eff.org/doc/control-spec.txt for all the new features,
439 including signals to emulate unix signals from any platform;
440 redirectstream; extendcircuit; mapaddress; getinfo; postdescriptor;
441 closestream; closecircuit; etc.
442 - Encode hashed controller passwords in hex instead of base64,
443 to make it easier to write controllers.
444 - Revise control spec and implementation to allow all log messages to
445 be sent to controller with their severities intact (suggested by
446 Matt Edman). Disable debug-level logs while delivering a debug-level
447 log to the controller, to prevent loop. Update TorControl to handle
450 o New config options/defaults:
451 - Begin scrubbing sensitive strings from logs by default. Turn off
452 the config option SafeLogging if you need to do debugging.
453 - New exit policy: accept most low-numbered ports, rather than
454 rejecting most low-numbered ports.
455 - Put a note in the torrc about abuse potential with the default
457 - Add support for CONNECTing through https proxies, with "HttpsProxy"
459 - Add HttpProxyAuthenticator and HttpsProxyAuthenticator support
460 based on patch from Adam Langley (basic auth only).
461 - Bump the default BandwidthRate from 1 MB to 2 MB, to accommodate
462 the fast servers that have been joining lately. (Clients are now
463 willing to load balance over up to 2 MB of advertised bandwidth
465 - New config option MaxAdvertisedBandwidth which lets you advertise
466 a low bandwidthrate (to not attract as many circuits) while still
467 allowing a higher bandwidthrate in reality.
468 - Require BandwidthRate to be at least 20kB/s for servers.
469 - Add a NoPublish config option, so you can be a server (e.g. for
470 testing running Tor servers in other Tor networks) without
471 publishing your descriptor to the primary dirservers.
472 - Add a new AddressMap config directive to rewrite incoming socks
473 addresses. This lets you, for example, declare an implicit
474 required exit node for certain sites.
475 - Add a new TrackHostExits config directive to trigger addressmaps
476 for certain incoming socks addresses -- for sites that break when
477 your exit keeps changing (based on patch from Mike Perry).
478 - Split NewCircuitPeriod option into NewCircuitPeriod (30 secs),
479 which describes how often we retry making new circuits if current
480 ones are dirty, and MaxCircuitDirtiness (10 mins), which describes
481 how long we're willing to make use of an already-dirty circuit.
482 - Change compiled-in SHUTDOWN_WAIT_LENGTH from a fixed 30 secs to
483 a config option "ShutdownWaitLength" (when using kill -INT on
485 - Fix an edge case in parsing config options: if they say "--"
486 on the commandline, it's not a config option (thanks weasel).
487 - New config option DirAllowPrivateAddresses for authdirservers.
488 Now by default they refuse router descriptors that have non-IP or
489 private-IP addresses.
490 - Change DirFetchPeriod/StatusFetchPeriod to have a special "Be
491 smart" default value: low for servers and high for clients.
492 - Some people were putting "Address " in their torrc, and they had
493 a buggy resolver that resolved " " to 0.0.0.0. Oops.
494 - If DataDir is ~/.tor, and that expands to /.tor, then default to
495 LOCALSTATEDIR/tor instead.
496 - Implement --verify-config command-line option to check if your torrc
497 is valid without actually launching Tor.
499 o Logging improvements:
500 - When dirservers refuse a server descriptor, we now log its
501 contactinfo, platform, and the poster's IP address.
502 - Only warn once per nickname from add_nickname_list_to_smartlist()
503 per failure, so an entrynode or exitnode choice that's down won't
505 - When we're connecting to an OR and he's got a different nickname/key
506 than we were expecting, only complain loudly if we're an OP or a
507 dirserver. Complaining loudly to the OR admins just confuses them.
508 - Whine at you if you're a server and you don't set your contactinfo.
509 - Warn when exit policy implicitly allows local addresses.
510 - Give a better warning when some other server advertises an
511 ORPort that is actually an apache running ssl.
512 - If we get an incredibly skewed timestamp from a dirserver mirror
513 that isn't a verified OR, don't warn -- it's probably him that's
515 - When a dirserver causes you to give a warn, mention which dirserver
517 - Initialize libevent later in the startup process, so the logs are
518 already established by the time we start logging libevent warns.
519 - Use correct errno on win32 if libevent fails.
520 - Check and warn about known-bad/slow libevent versions.
521 - Stop warning about sigpipes in the logs. We're going to
522 pretend that getting these occassionally is normal and fine.
524 o New contrib scripts:
525 - New experimental script tor/contrib/exitlist: a simple python
526 script to parse directories and find Tor nodes that exit to listed
528 - New experimental script tor/contrib/ExerciseServer.py (needs more
529 work) that uses the controller interface to build circuits and
530 fetch pages over them. This will help us bootstrap servers that
531 have lots of capacity but haven't noticed it yet.
532 - New experimental script tor/contrib/PathDemo.py (needs more work)
533 that uses the controller interface to let you choose whole paths
535 "<hostname>.<path,separated by dots>.<length of path>.path"
536 - New contributed script "privoxy-tor-toggle" to toggle whether
537 Privoxy uses Tor. Seems to be configured for Debian by default.
538 - Have torctl.in/tor.sh.in check for location of su binary (needed
542 - chdir() to your datadirectory at the *end* of the daemonize process,
543 not the beginning. This was a problem because the first time you
544 run tor, if your datadir isn't there, and you have runasdaemon set
545 to 1, it will try to chdir to it before it tries to create it. Oops.
546 - Fix several double-mark-for-close bugs, e.g. where we were finding
547 a conn for a cell even if that conn is already marked for close.
548 - Stop most cases of hanging up on a socks connection without sending
550 - Fix a bug in the RPM package: set home directory for _tor to
551 something more reasonable when first installing.
552 - Stop putting nodename in the Platform string in server descriptors.
553 It doesn't actually help, and it is confusing/upsetting some people.
554 - When using preferred entry or exit nodes, ignore whether the
555 circuit wants uptime or capacity. They asked for the nodes, they
557 - Tie MAX_DIR_SIZE to MAX_BUF_SIZE, so now directory sizes won't get
558 artificially capped at 500kB.
559 - Cache local dns resolves correctly even when they're .exit
561 - If we're hibernating and we get a SIGINT, exit immediately.
562 - tor-resolve requests were ignoring .exit if there was a working circuit
563 they could use instead.
564 - Pay more attention to the ClientOnly config option.
565 - Resolve OS X installer bugs: stop claiming to be 0.0.9.2 in certain
566 installer screens; and don't put stuff into StartupItems unless
567 the user asks you to.
570 - Rewrite address "serifos.exit" to "externalIP.serifos.exit"
571 rather than just rejecting it.
572 - If our clock jumps forward by 100 seconds or more, assume something
573 has gone wrong with our network and abandon all not-yet-used circs.
574 - When an application is using socks5, give him the whole variety of
575 potential socks5 responses (connect refused, host unreachable, etc),
576 rather than just "success" or "failure".
577 - A more sane version numbering system. See
578 http://tor.eff.org/cvs/tor/doc/version-spec.txt for details.
579 - Change version parsing logic: a version is "obsolete" if it is not
580 recommended and (1) there is a newer recommended version in the
581 same series, or (2) there are no recommended versions in the same
582 series, but there are some recommended versions in a newer series.
583 A version is "new" if it is newer than any recommended version in
585 - Report HTTP reasons to client when getting a response from directory
586 servers -- so you can actually know what went wrong.
587 - Reject odd-looking addresses at the client (e.g. addresses that
588 contain a colon), rather than having the server drop them because
590 - Stop publishing socksport in the directory, since it's not
591 actually meant to be public. For compatibility, publish a 0 there
593 - Since we ship our own Privoxy on OS X, tweak it so it doesn't write
594 cookies to disk and doesn't log each web request to disk. (Thanks
595 to Brett Carrington for pointing this out.)
596 - Add OSX uninstall instructions. An actual uninstall script will
598 - Add "opt hibernating 1" to server descriptor to make it clearer
599 whether the server is hibernating.
602 Changes in version 0.0.9.10 - 2005-06-16
603 o Bugfixes on 0.0.9.x (backported from 0.1.0.10):
604 - Refuse relay cells that claim to have a length larger than the
605 maximum allowed. This prevents a potential attack that could read
606 arbitrary memory (e.g. keys) from an exit server's process.
609 Changes in version 0.0.9.9 - 2005-04-23
610 o Bugfixes on 0.0.9.x:
611 - If unofficial Tor clients connect and send weird TLS certs, our
612 Tor server triggers an assert. This release contains a minimal
613 backport from the broader fix that we put into 0.1.0.4-rc.
616 Changes in version 0.0.9.8 - 2005-04-07
617 o Bugfixes on 0.0.9.x:
618 - We have a bug that I haven't found yet. Sometimes, very rarely,
619 cpuworkers get stuck in the 'busy' state, even though the cpuworker
620 thinks of itself as idle. This meant that no new circuits ever got
621 established. Here's a workaround to kill any cpuworker that's been
622 busy for more than 100 seconds.
625 Changes in version 0.0.9.7 - 2005-04-01
626 o Bugfixes on 0.0.9.x:
627 - Fix another race crash bug (thanks to Glenn Fink for reporting).
628 - Compare identity to identity, not to nickname, when extending to
629 a router not already in the directory. This was preventing us from
630 extending to unknown routers. Oops.
631 - Make sure to create OS X Tor user in <500 range, so we aren't
632 creating actual system users.
633 - Note where connection-that-hasn't-sent-end was marked, and fix
634 a few really loud instances of this harmless bug (it's fixed more
638 Changes in version 0.0.9.6 - 2005-03-24
639 o Bugfixes on 0.0.9.x (crashes and asserts):
640 - Add new end stream reasons to maintainance branch. Fix bug where
641 reason (8) could trigger an assert. Prevent bug from recurring.
642 - Apparently win32 stat wants paths to not end with a slash.
643 - Fix assert triggers in assert_cpath_layer_ok(), where we were
644 blowing away the circuit that conn->cpath_layer points to, then
645 checking to see if the circ is well-formed. Backport check to make
646 sure we dont use the cpath on a closed connection.
647 - Prevent circuit_resume_edge_reading_helper() from trying to package
648 inbufs for marked-for-close streams.
649 - Don't crash on hup if your options->address has become unresolvable.
650 - Some systems (like OS X) sometimes accept() a connection and tell
651 you the remote host is 0.0.0.0:0. If this happens, due to some
652 other mis-features, we get confused; so refuse the conn for now.
654 o Bugfixes on 0.0.9.x (other):
655 - Fix harmless but scary "Unrecognized content encoding" warn message.
656 - Add new stream error reason: TORPROTOCOL reason means "you are not
657 speaking a version of Tor I understand; say bye-bye to your stream."
658 - Be willing to cache directories from up to ROUTER_MAX_AGE seconds
659 into the future, now that we are more tolerant of skew. This
660 resolves a bug where a Tor server would refuse to cache a directory
661 because all the directories it gets are too far in the future;
662 yet the Tor server never logs any complaints about clock skew.
663 - Mac packaging magic: make man pages useable, and do not overwrite
664 existing torrc files.
665 - Make OS X log happily to /var/log/tor/tor.log
668 Changes in version 0.0.9.5 - 2005-02-22
669 o Bugfixes on 0.0.9.x:
670 - Fix an assert race at exit nodes when resolve requests fail.
671 - Stop picking unverified dir mirrors--it only leads to misery.
672 - Patch from Matt Edman to make NT services work better. Service
673 support is still not compiled into the executable by default.
674 - Patch from Dmitri Bely so the Tor service runs better under
675 the win32 SYSTEM account.
676 - Make tor-resolve actually work (?) on Win32.
677 - Fix a sign bug when getrlimit claims to have 4+ billion
678 file descriptors available.
679 - Stop refusing to start when bandwidthburst == bandwidthrate.
680 - When create cells have been on the onion queue more than five
681 seconds, just send back a destroy and take them off the list.
684 Changes in version 0.0.9.4 - 2005-02-03
686 - Fix an assert bug that took down most of our servers: when
687 a server claims to have 1 GB of bandwidthburst, don't
689 - Don't crash as badly if we have spawned the max allowed number
690 of dnsworkers, or we're out of file descriptors.
691 - Block more file-sharing ports in the default exit policy.
692 - MaxConn is now automatically set to the hard limit of max
693 file descriptors we're allowed (ulimit -n), minus a few for
695 - Give a clearer message when servers need to raise their
696 ulimit -n when they start running out of file descriptors.
697 - SGI Compatibility patches from Jan Schaumann.
698 - Tolerate a corrupt cached directory better.
699 - When a dirserver hasn't approved your server, list which one.
700 - Go into soft hibernation after 95% of the bandwidth is used,
701 not 99%. This is especially important for daily hibernators who
702 have a small accounting max. Hopefully it will result in fewer
703 cut connections when the hard hibernation starts.
704 - Load-balance better when using servers that claim more than
706 - Make NT services work (experimental, only used if compiled in).
709 Changes in version 0.0.9.3 - 2005-01-21
711 - Backport the cpu use fixes from main branch, so busy servers won't
712 need as much processor time.
713 - Work better when we go offline and then come back, or when we
714 run Tor at boot before the network is up. We do this by
715 optimistically trying to fetch a new directory whenever an
716 application request comes in and we think we're offline -- the
717 human is hopefully a good measure of when the network is back.
718 - Backport some minimal hidserv bugfixes: keep rend circuits open as
719 long as you keep using them; actually publish hidserv descriptors
720 shortly after they change, rather than waiting 20-40 minutes.
721 - Enable Mac startup script by default.
722 - Fix duplicate dns_cancel_pending_resolve reported by Giorgos Pallas.
723 - When you update AllowUnverifiedNodes or FirewallPorts via the
724 controller's setconf feature, we were always appending, never
726 - When you update HiddenServiceDir via setconf, it was screwing up
727 the order of reading the lines, making it fail.
728 - Do not rewrite a cached directory back to the cache; otherwise we
729 will think it is recent and not fetch a newer one on startup.
730 - Workaround for webservers that lie about Content-Encoding: Tor
731 now tries to autodetect compressed directories and compression
732 itself. This lets us Proxypass dir fetches through apache.
735 Changes in version 0.0.9.2 - 2005-01-04
736 o Bugfixes on 0.0.9 (crashes and asserts):
737 - Fix an assert on startup when the disk is full and you're logging
739 - If you do socks4 with an IP of 0.0.0.x but *don't* provide a socks4a
740 style address, then we'd crash.
741 - Fix an assert trigger when the running-routers string we get from
742 a dirserver is broken.
743 - Make worker threads start and run on win32. Now win32 servers
745 - Bandaid (not actually fix, but now it doesn't crash) an assert
746 where the dns worker dies mysteriously and the main Tor process
747 doesn't remember anything about the address it was resolving.
749 o Bugfixes on 0.0.9 (Win32):
750 - Workaround for brain-damaged __FILE__ handling on MSVC: keep Nick's
751 name out of the warning/assert messages.
752 - Fix a superficial "unhandled error on read" bug on win32.
753 - The win32 installer no longer requires a click-through for our
754 license, since our Free Software license grants rights but does not
756 - Win32: When connecting to a dirserver fails, try another one
757 immediately. (This was already working for non-win32 Tors.)
758 - Stop trying to parse $HOME on win32 when hunting for default
760 - Make tor-resolve.c work on win32 by calling network_init().
762 o Bugfixes on 0.0.9 (other):
763 - Make 0.0.9.x build on Solaris again.
764 - Due to a fencepost error, we were blowing away the \n when reporting
765 confvalue items in the controller. So asking for multiple config
766 values at once couldn't work.
767 - When listing circuits that are pending on an opening OR connection,
768 if we're an OR we were listing circuits that *end* at us as
769 being pending on every listener, dns/cpu worker, etc. Stop that.
770 - Dirservers were failing to create 'running-routers' or 'directory'
771 strings if we had more than some threshold of routers. Fix them so
772 they can handle any number of routers.
773 - Fix a superficial "Duplicate mark for close" bug.
774 - Stop checking for clock skew for OR connections, even for servers.
775 - Fix a fencepost error that was chopping off the last letter of any
776 nickname that is the maximum allowed nickname length.
777 - Update URLs in log messages so they point to the new website.
778 - Fix a potential problem in mangling server private keys while
779 writing to disk (not triggered yet, as far as we know).
780 - Include the licenses for other free software we include in Tor,
781 now that we're shipping binary distributions more regularly.
784 Changes in version 0.0.9.1 - 2004-12-15
786 - Make hibernation actually work.
787 - Make HashedControlPassword config option work.
788 - When we're reporting event circuit status to a controller,
789 don't use the stream status code.
792 Changes in version 0.0.9 - 2004-12-12
793 o Bugfixes on 0.0.8.1 (Crashes and asserts):
794 - Catch and ignore SIGXFSZ signals when log files exceed 2GB; our
795 write() call will fail and we handle it there.
796 - When we run out of disk space, or other log writing error, don't
797 crash. Just stop logging to that log and continue.
798 - Fix isspace() and friends so they still make Solaris happy
799 but also so they don't trigger asserts on win32.
800 - Fix assert failure on malformed socks4a requests.
801 - Fix an assert bug where a hidden service provider would fail if
802 the first hop of his rendezvous circuit was down.
803 - Better handling of size_t vs int, so we're more robust on 64
806 o Bugfixes on 0.0.8.1 (Win32):
807 - Make windows sockets actually non-blocking (oops), and handle
808 win32 socket errors better.
809 - Fix parse_iso_time on platforms without strptime (eg win32).
810 - win32: when being multithreaded, leave parent fdarray open.
811 - Better handling of winsock includes on non-MSV win32 compilers.
812 - Change our file IO stuff (especially wrt OpenSSL) so win32 is
814 - Make unit tests work on win32.
816 o Bugfixes on 0.0.8.1 (Path selection and streams):
817 - Calculate timeout for waiting for a connected cell from the time
818 we sent the begin cell, not from the time the stream started. If
819 it took a long time to establish the circuit, we would time out
820 right after sending the begin cell.
821 - Fix router_compare_addr_to_addr_policy: it was not treating a port
822 of * as always matching, so we were picking reject *:* nodes as
823 exit nodes too. Oops.
824 - When read() failed on a stream, we would close it without sending
825 back an end. So 'connection refused' would simply be ignored and
826 the user would get no response.
827 - Stop a sigpipe: when an 'end' cell races with eof from the app,
828 we shouldn't hold-open-until-flush if the eof arrived first.
829 - Let resolve conns retry/expire also, rather than sticking around
831 - Fix more dns related bugs: send back resolve_failed and end cells
832 more reliably when the resolve fails, rather than closing the
833 circuit and then trying to send the cell. Also attach dummy resolve
834 connections to a circuit *before* calling dns_resolve(), to fix
835 a bug where cached answers would never be sent in RESOLVED cells.
837 o Bugfixes on 0.0.8.1 (Circuits):
838 - Finally fix a bug that's been plaguing us for a year:
839 With high load, circuit package window was reaching 0. Whenever
840 we got a circuit-level sendme, we were reading a lot on each
841 socket, but only writing out a bit. So we would eventually reach
842 eof. This would be noticed and acted on even when there were still
843 bytes sitting in the inbuf.
844 - Use identity comparison, not nickname comparison, to choose which
845 half of circuit-ID-space each side gets to use. This is needed
846 because sometimes we think of a router as a nickname, and sometimes
847 as a hex ID, and we can't predict what the other side will do.
849 o Bugfixes on 0.0.8.1 (Other):
850 - Fix a whole slew of memory leaks.
851 - Disallow NDEBUG. We don't ever want anybody to turn off debug.
852 - If we are using select, make sure we stay within FD_SETSIZE.
853 - When poll() is interrupted, we shouldn't believe the revents values.
854 - Add a FAST_SMARTLIST define to optionally inline smartlist_get
855 and smartlist_len, which are two major profiling offenders.
856 - If do_hup fails, actually notice.
857 - Flush the log file descriptor after we print "Tor opening log file",
858 so we don't see those messages days later.
859 - Hidden service operators now correctly handle version 1 style
860 INTRODUCE1 cells (nobody generates them still, so not a critical
862 - Handle more errnos from accept() without closing the listener.
863 Some OpenBSD machines were closing their listeners because
864 they ran out of file descriptors.
865 - Some people had wrapped their tor client/server in a script
866 that would restart it whenever it died. This did not play well
867 with our "shut down if your version is obsolete" code. Now people
868 don't fetch a new directory if their local cached version is
870 - Make our autogen.sh work on ksh as well as bash.
871 - Better torrc example lines for dirbindaddress and orbindaddress.
872 - Improved bounds checking on parsed ints (e.g. config options and
873 the ones we find in directories.)
874 - Stop using separate defaults for no-config-file and
875 empty-config-file. Now you have to explicitly turn off SocksPort,
876 if you don't want it open.
877 - We were starting to daemonize before we opened our logs, so if
878 there were any problems opening logs, we would complain to stderr,
879 which wouldn't work, and then mysteriously exit.
880 - If a verified OR connects to us before he's uploaded his descriptor,
881 or we verify him and hup but he still has the original TLS
882 connection, then conn->nickname is still set like he's unverified.
884 o Code security improvements, inspired by Ilja:
885 - tor_snprintf wrapper over snprintf with consistent (though not C99)
887 - Replace sprintf with tor_snprintf. (I think they were all safe, but
889 - Replace strcpy/strncpy with strlcpy in more places.
890 - Avoid strcat; use tor_snprintf or strlcat instead.
892 o Features (circuits and streams):
893 - New circuit building strategy: keep a list of ports that we've
894 used in the past 6 hours, and always try to have 2 circuits open
895 or on the way that will handle each such port. Seed us with port
896 80 so web users won't complain that Tor is "slow to start up".
897 - Make kill -USR1 dump more useful stats about circuits.
898 - When warning about retrying or giving up, print the address, so
899 the user knows which one it's talking about.
900 - If you haven't used a clean circuit in an hour, throw it away,
901 just to be on the safe side. (This means after 6 hours a totally
902 unused Tor client will have no circuits open.)
903 - Support "foo.nickname.exit" addresses, to let Alice request the
904 address "foo" as viewed by exit node "nickname". Based on a patch
906 - If your requested entry or exit node has advertised bandwidth 0,
908 - Be more greedy about filling up relay cells -- we try reading again
909 once we've processed the stuff we read, in case enough has arrived
910 to fill the last cell completely.
911 - Refuse application socks connections to port 0.
912 - Use only 0.0.9pre1 and later servers for resolve cells.
914 o Features (bandwidth):
915 - Hibernation: New config option "AccountingMax" lets you
916 set how many bytes per month (in each direction) you want to
917 allow your server to consume. Rather than spreading those
918 bytes out evenly over the month, we instead hibernate for some
919 of the month and pop up at a deterministic time, work until
920 the bytes are consumed, then hibernate again. Config option
921 "MonthlyAccountingStart" lets you specify which day of the month
922 your billing cycle starts on.
923 - Implement weekly/monthly/daily accounting: now you specify your
924 hibernation properties by
925 AccountingMax N bytes|KB|MB|GB|TB
926 AccountingStart day|week|month [day] HH:MM
927 Defaults to "month 1 0:00".
928 - Let bandwidth and interval config options be specified as 5 bytes,
929 kb, kilobytes, etc; and as seconds, minutes, hours, days, weeks.
931 o Features (directories):
932 - New "router-status" line in directory, to better bind each verified
933 nickname to its identity key.
934 - Clients can ask dirservers for /dir.z to get a compressed version
935 of the directory. Only works for servers running 0.0.9, of course.
936 - Make clients cache directories and use them to seed their router
937 lists at startup. This means clients have a datadir again.
938 - Respond to content-encoding headers by trying to uncompress as
940 - Clients and servers now fetch running-routers; cache
941 running-routers; compress running-routers; serve compressed
943 - Make moria2 advertise a dirport of 80, so people behind firewalls
944 will be able to get a directory.
946 - Dirservers translate requests for http://%s:%d/x to /x
947 - You can specify "HttpProxy %s[:%d]" and all dir fetches will
948 be routed through this host.
949 - Clients ask for /tor/x rather than /x for new enough dirservers.
950 This way we can one day coexist peacefully with apache.
951 - Clients specify a "Host: %s%d" http header, to be compatible
952 with more proxies, and so running squid on an exit node can work.
953 - Protect dirservers from overzealous descriptor uploading -- wait
954 10 seconds after directory gets dirty, before regenerating.
956 o Features (packages and install):
957 - Add NSI installer contributed by J Doe.
958 - Apply NT service patch from Osamu Fujino. Still needs more work.
959 - Commit VC6 and VC7 workspace/project files.
960 - Commit a tor.spec for making RPM files, with help from jbash.
961 - Add contrib/torctl.in contributed by Glenn Fink.
962 - Make expand_filename handle ~ and ~username.
963 - Use autoconf to enable largefile support where necessary. Use
964 ftello where available, since ftell can fail at 2GB.
965 - Ship src/win32/ in the tarball, so people can use it to build.
966 - Make old win32 fall back to CWD if SHGetSpecialFolderLocation
969 o Features (ui controller):
970 - Control interface: a separate program can now talk to your
971 client/server over a socket, and get/set config options, receive
972 notifications of circuits and streams starting/finishing/dying,
973 bandwidth used, etc. The next step is to get some GUIs working.
974 Let us know if you want to help out. See doc/control-spec.txt .
975 - Ship a contrib/tor-control.py as an example script to interact
976 with the control port.
977 - "tor --hash-password zzyxz" will output a salted password for
978 use in authenticating to the control interface.
979 - Implement the control-spec's SAVECONF command, to write your
980 configuration to torrc.
981 - Get cookie authentication for the controller closer to working.
982 - When set_conf changes our server descriptor, upload a new copy.
983 But don't upload it too often if there are frequent changes.
985 o Features (config and command-line):
986 - Deprecate unofficial config option abbreviations, and abbreviations
987 not on the command line.
988 - Configuration infrastructure support for warning on obsolete
990 - Give a slightly more useful output for "tor -h".
991 - Break DirFetchPostPeriod into:
992 - DirFetchPeriod for fetching full directory,
993 - StatusFetchPeriod for fetching running-routers,
994 - DirPostPeriod for posting server descriptor,
995 - RendPostPeriod for posting hidden service descriptors.
996 - New log format in config:
997 "Log minsev[-maxsev] stdout|stderr|syslog" or
998 "Log minsev[-maxsev] file /var/foo"
999 - DirPolicy config option, to let people reject incoming addresses
1000 from their dirserver.
1001 - "tor --list-fingerprint" will list your identity key fingerprint
1003 - Make tor --version --version dump the cvs Id of every file.
1004 - New 'MyFamily nick1,...' config option for a server to
1005 specify other servers that shouldn't be used in the same circuit
1006 with it. Only believed if nick1 also specifies us.
1007 - New 'NodeFamily nick1,nick2,...' config option for a client to
1008 specify nodes that it doesn't want to use in the same circuit.
1009 - New 'Redirectexit pattern address:port' config option for a
1010 server to redirect exit connections, e.g. to a local squid.
1011 - Add "pass" target for RedirectExit, to make it easier to break
1012 out of a sequence of RedirectExit rules.
1013 - Make the dirservers file obsolete.
1014 - Include a dir-signing-key token in directories to tell the
1015 parsing entity which key is being used to sign.
1016 - Remove the built-in bulky default dirservers string.
1017 - New config option "Dirserver %s:%d [fingerprint]", which can be
1018 repeated as many times as needed. If no dirservers specified,
1019 default to moria1,moria2,tor26.
1020 - Make 'Routerfile' config option obsolete.
1021 - Discourage people from setting their dirfetchpostperiod more often
1022 than once per minute.
1025 - kill -USR2 now moves all logs to loglevel debug (kill -HUP to
1026 get back to normal.)
1027 - Accept *:706 (silc) in default exit policy.
1028 - Implement new versioning format for post 0.1.
1029 - Distinguish between TOR_TLS_CLOSE and TOR_TLS_ERROR, so we can
1030 log more informatively.
1031 - Check clock skew for verified servers, but allow unverified
1032 servers and clients to have any clock skew.
1033 - Make sure the hidden service descriptors are at a random offset
1034 from each other, to hinder linkability.
1035 - Clients now generate a TLS cert too, in preparation for having
1036 them act more like real nodes.
1037 - Add a pure-C tor-resolve implementation.
1038 - Use getrlimit and friends to ensure we can reach MaxConn (currently
1039 1024) file descriptors.
1040 - Raise the max dns workers from 50 to 100.
1043 Changes in version 0.0.8.1 - 2004-10-13
1045 - Fix a seg fault that can be triggered remotely for Tor
1046 clients/servers with an open dirport.
1047 - Fix a rare assert trigger, where routerinfos for entries in
1048 our cpath would expire while we're building the path.
1049 - Fix a bug in OutboundBindAddress so it (hopefully) works.
1050 - Fix a rare seg fault for people running hidden services on
1051 intermittent connections.
1052 - Fix a bug in parsing opt keywords with objects.
1053 - Fix a stale pointer assert bug when a stream detaches and
1055 - Fix a string format vulnerability (probably not exploitable)
1056 in reporting stats locally.
1057 - Fix an assert trigger: sometimes launching circuits can fail
1058 immediately, e.g. because too many circuits have failed recently.
1059 - Fix a compile warning on 64 bit platforms.
1062 Changes in version 0.0.8 - 2004-08-25
1064 - Made our unit tests compile again on OpenBSD 3.5, and tor
1065 itself compile again on OpenBSD on a sparc64.
1066 - We were neglecting milliseconds when logging on win32, so
1067 everything appeared to happen at the beginning of each second.
1068 - Check directory signature _before_ you decide whether you're
1069 you're running an obsolete version and should exit.
1070 - Check directory signature _before_ you parse the running-routers
1071 list to decide who's running.
1072 - Check return value of fclose while writing to disk, so we don't
1073 end up with broken files when servers run out of disk space.
1074 - Port it to SunOS 5.9 / Athena
1075 - Fix two bugs in saving onion keys to disk when rotating, so
1076 hopefully we'll get fewer people using old onion keys.
1077 - Remove our mostly unused -- and broken -- hex_encode()
1078 function. Use base16_encode() instead. (Thanks to Timo Lindfors
1079 for pointing out this bug.)
1080 - Only pick and establish intro points after we've gotten a
1082 - Fix assert triggers: if the other side returns an address 0.0.0.0,
1083 don't put it into the client dns cache.
1084 - If a begin failed due to exit policy, but we believe the IP
1085 address should have been allowed, switch that router to exitpolicy
1086 reject *:* until we get our next directory.
1089 - 'Extend' relay cell payloads now include the digest of the
1090 intended next hop's identity key. Now we can verify that we're
1091 extending to the right router, and also extend to routers we
1092 hadn't heard of before.
1095 - Tor nodes can now act as relays (with an advertised ORPort)
1096 without being manually verified by the dirserver operators.
1097 - Uploaded descriptors of unverified routers are now accepted
1098 by the dirservers, and included in the directory.
1099 - Verified routers are listed by nickname in the running-routers
1100 list; unverified routers are listed as "$<fingerprint>".
1101 - We now use hash-of-identity-key in most places rather than
1102 nickname or addr:port, for improved security/flexibility.
1103 - AllowUnverifiedNodes config option to let circuits choose no-name
1104 routers in entry,middle,exit,introduction,rendezvous positions.
1105 Allow middle and rendezvous positions by default.
1106 - When picking unverified routers, skip those with low uptime and/or
1107 low bandwidth, depending on what properties you care about.
1108 - ClientOnly option for nodes that never want to become servers.
1109 - Directory caching.
1110 - "AuthoritativeDir 1" option for the official dirservers.
1111 - Now other nodes (clients and servers) will cache the latest
1112 directory they've pulled down.
1113 - They can enable their DirPort to serve it to others.
1114 - Clients will pull down a directory from any node with an open
1115 DirPort, and check the signature/timestamp correctly.
1116 - Authoritative dirservers now fetch directories from other
1117 authdirservers, to stay better synced.
1118 - Running-routers list tells who's down also, along with noting
1119 if they're verified (listed by nickname) or unverified (listed
1121 - Allow dirservers to serve running-router list separately.
1122 This isn't used yet.
1123 - You can now fetch $DIRURL/running-routers to get just the
1124 running-routers line, not the whole descriptor list. (But
1125 clients don't use this yet.)
1126 - Clients choose nodes proportional to advertised bandwidth.
1127 - Clients avoid using nodes with low uptime as introduction points.
1128 - Handle servers with dynamic IP addresses: don't just replace
1129 options->Address with the resolved one at startup, and
1130 detect our address right before we make a routerinfo each time.
1131 - 'FascistFirewall' option to pick dirservers and ORs on specific
1132 ports; plus 'FirewallPorts' config option to tell FascistFirewall
1133 which ports are open. (Defaults to 80,443)
1134 - Try other dirservers immediately if the one you try is down. This
1135 should tolerate down dirservers better now.
1136 - ORs connect-on-demand to other ORs
1137 - If you get an extend cell to an OR you're not connected to,
1138 connect, handshake, and forward the create cell.
1139 - The authoritative dirservers stay connected to everybody,
1140 and everybody stays connected to 0.0.7 servers, but otherwise
1141 clients/servers expire unused connections after 5 minutes.
1142 - When servers get a sigint, they delay 30 seconds (refusing new
1143 connections) then exit. A second sigint causes immediate exit.
1144 - File and name management:
1145 - Look for .torrc if no CONFDIR "torrc" is found.
1146 - If no datadir is defined, then choose, make, and secure ~/.tor
1148 - If torrc not found, exitpolicy reject *:*.
1149 - Expands ~/ in filenames to $HOME/ (but doesn't yet expand ~arma).
1150 - If no nickname is defined, derive default from hostname.
1151 - Rename secret key files, e.g. identity.key -> secret_id_key,
1152 to discourage people from mailing their identity key to tor-ops.
1153 - Refuse to build a circuit before the directory has arrived --
1154 it won't work anyway, since you won't know the right onion keys
1156 - Parse tor version numbers so we can do an is-newer-than check
1157 rather than an is-in-the-list check.
1158 - New socks command 'resolve', to let us shim gethostbyname()
1160 - A 'tor_resolve' script to access the socks resolve functionality.
1161 - A new socks-extensions.txt doc file to describe our
1162 interpretation and extensions to the socks protocols.
1163 - Add a ContactInfo option, which gets published in descriptor.
1164 - Write tor version at the top of each log file
1165 - New docs in the tarball:
1167 - Document that you should proxy your SSL traffic too.
1168 - Log a warning if the user uses an unsafe socks variant, so people
1169 are more likely to learn about privoxy or socat.
1170 - Log a warning if you're running an unverified server, to let you
1171 know you might want to get it verified.
1172 - Change the default exit policy to reject the default edonkey,
1173 kazaa, gnutella ports.
1174 - Add replace_file() to util.[ch] to handle win32's rename().
1175 - Publish OR uptime in descriptor (and thus in directory) too.
1176 - Remember used bandwidth (both in and out), and publish 15-minute
1177 snapshots for the past day into our descriptor.
1178 - Be more aggressive about trying to make circuits when the network
1179 has changed (e.g. when you unsuspend your laptop).
1180 - Check for time skew on http headers; report date in response to
1182 - If the entrynode config line has only one node, don't pick it as
1184 - Add strict{entry|exit}nodes config options. If set to 1, then
1185 we refuse to build circuits that don't include the specified entry
1187 - OutboundBindAddress config option, to bind to a specific
1188 IP address for outgoing connect()s.
1189 - End truncated log entries (e.g. directories) with "[truncated]".
1192 Changes in version 0.0.7.3 - 2004-08-12
1193 o Stop dnsworkers from triggering an assert failure when you
1194 ask them to resolve the host "".
1197 Changes in version 0.0.7.2 - 2004-07-07
1198 o A better fix for the 0.0.0.0 problem, that will hopefully
1199 eliminate the remaining related assertion failures.
1202 Changes in version 0.0.7.1 - 2004-07-04
1203 o When an address resolves to 0.0.0.0, treat it as a failed resolve,
1204 since internally we use 0.0.0.0 to signify "not yet resolved".
1207 Changes in version 0.0.7 - 2004-06-07
1208 o Fixes for crashes and other obnoxious bugs:
1209 - Fix an epipe bug: sometimes when directory connections failed
1210 to connect, we would give them a chance to flush before closing
1212 - When we detached from a circuit because of resolvefailed, we
1213 would immediately try the same circuit twice more, and then
1214 give up on the resolve thinking we'd tried three different
1216 - Limit the number of intro circuits we'll attempt to build for a
1217 hidden service per 15-minute period.
1218 - Check recommended-software string *early*, before actually parsing
1219 the directory. Thus we can detect an obsolete version and exit,
1220 even if the new directory format doesn't parse.
1221 o Fixes for security bugs:
1222 - Remember which nodes are dirservers when you startup, and if a
1223 random OR enables his dirport, don't automatically assume he's
1224 a trusted dirserver.
1226 - Directory connections were asking the wrong poll socket to
1227 start writing, and not asking themselves to start writing.
1228 - When we detached from a circuit because we sent a begin but
1229 didn't get a connected, we would use it again the first time;
1230 but after that we would correctly switch to a different one.
1231 - Stop warning when the first onion decrypt attempt fails; they
1232 will sometimes legitimately fail now that we rotate keys.
1233 - Override unaligned-access-ok check when $host_cpu is ia64 or
1234 arm. Apparently they allow it but the kernel whines.
1235 - Dirservers try to reconnect periodically too, in case connections
1237 - Fix some memory leaks in directory servers.
1238 - Allow backslash in Win32 filenames.
1239 - Made Tor build complain-free on FreeBSD, hopefully without
1240 breaking other BSD builds. We'll see.
1241 - Check directory signatures based on name of signer, not on whom
1242 we got the directory from. This will let us cache directories more
1244 - Rotate dnsworkers and cpuworkers on SIGHUP, so they get new config
1247 - Doxygen markup on all functions and global variables.
1248 - Make directory functions update routerlist, not replace it. So
1249 now directory disagreements are not so critical a problem.
1250 - Remove the upper limit on number of descriptors in a dirserver's
1251 directory (not that we were anywhere close).
1252 - Allow multiple logfiles at different severity ranges.
1253 - Allow *BindAddress to specify ":port" rather than setting *Port
1254 separately. Allow multiple instances of each BindAddress config
1255 option, so you can bind to multiple interfaces if you want.
1256 - Allow multiple exit policy lines, which are processed in order.
1257 Now we don't need that huge line with all the commas in it.
1258 - Enable accept/reject policies on SOCKS connections, so you can bind
1259 to 0.0.0.0 but still control who can use your OP.
1260 - Updated the man page to reflect these features.
1263 Changes in version 0.0.6.2 - 2004-05-16
1264 o Our integrity-checking digest was checking only the most recent cell,
1265 not the previous cells like we'd thought.
1266 Thanks to Stefan Mark for finding the flaw!
1269 Changes in version 0.0.6.1 - 2004-05-06
1270 o Fix two bugs in our AES counter-mode implementation (this affected
1271 onion-level stream encryption, but not TLS-level). It turns
1272 out we were doing something much more akin to a 16-character
1273 polyalphabetic cipher. Oops.
1274 Thanks to Stefan Mark for finding the flaw!
1275 o Retire moria3 as a directory server, and add tor26 as a directory
1279 Changes in version 0.0.6 - 2004-05-02
1281 - Hidden services and rendezvous points are implemented. Go to
1282 http://6sxoyfb3h2nvok2d.onion/ for an index of currently available
1283 hidden services. (This only works via a socks4a proxy such as
1284 Privoxy, and currently it's quite slow.)
1285 - We now rotate link (tls context) keys and onion keys.
1286 - CREATE cells now include oaep padding, so you can tell
1287 if you decrypted them correctly.
1288 - Retry stream correctly when we fail to connect because of
1289 exit-policy-reject (should try another) or can't-resolve-address.
1290 - When we hup a dirserver and we've *removed* a server from the
1291 approved-routers list, now we remove that server from the
1292 in-memory directories too.
1293 - Add bandwidthburst to server descriptor.
1294 - Directories now say which dirserver signed them.
1295 - Use a tor_assert macro that logs failed assertions too.
1296 - Since we don't support truncateds much, don't bother sending them;
1297 just close the circ.
1298 - Fetch randomness from /dev/urandom better (not via fopen/fread)
1299 - Better debugging for tls errors
1300 - Set Content-Type on the directory and hidserv descriptor.
1301 - Remove IVs from cipher code, since AES-ctr has none.
1303 - Fix an assert trigger for exit nodes that's been plaguing us since
1304 the days of 0.0.2prexx (thanks weasel!)
1305 - Fix a bug where we were closing tls connections intermittently.
1306 It turns out openssl keeps its errors around -- so if an error
1307 happens, and you don't ask about it, and then another openssl
1308 operation happens and succeeds, and you ask if there was an error,
1309 it tells you about the first error.
1310 - Fix a bug that's been lurking since 27 may 03 (!)
1311 When passing back a destroy cell, we would use the wrong circ id.
1312 - Don't crash if a conn that sent a begin has suddenly lost its circuit.
1313 - Some versions of openssl have an SSL_pending function that erroneously
1314 returns bytes when there is a non-application record pending.
1315 - Win32 fixes. Tor now compiles on win32 with no warnings/errors.
1316 o We were using an array of length zero in a few places.
1317 o Win32's gethostbyname can't resolve an IP to an IP.
1318 o Win32's close can't close a socket.
1319 o Handle windows socket errors correctly.
1321 - check for <sys/limits.h> so we build on FreeBSD again, and
1322 <machine/limits.h> for NetBSD.
1325 Changes in version 0.0.5 - 2004-03-30
1326 o Install torrc as torrc.sample -- we no longer clobber your
1328 o Fix mangled-state bug in directory fetching (was causing sigpipes).
1329 o Only build circuits after we've fetched the directory: clients were
1330 using only the directory servers before they'd fetched a directory.
1331 This also means longer startup time; so it goes.
1332 o Fix an assert trigger where an OP would fail to handshake, and we'd
1333 expect it to have a nickname.
1334 o Work around a tsocks bug: do a socks reject when AP connection dies
1335 early, else tsocks goes into an infinite loop.
1336 o Hold socks connection open until reply is flushed (if possible)
1337 o Make exit nodes resolve IPs to IPs immediately, rather than asking
1338 the dns farm to do it.
1339 o Fix c99 aliasing warnings in rephist.c
1340 o Don't include server descriptors that are older than 24 hours in the
1342 o Give socks 'reject' replies their whole 15s to attempt to flush,
1343 rather than seeing the 60s timeout and assuming the flush had failed.
1344 o Clean automake droppings from the cvs repository
1345 o Add in a 'notice' log level for things the operator should hear
1346 but that aren't warnings
1349 Changes in version 0.0.4 - 2004-03-26
1350 o When connecting to a dirserver or OR and the network is down,
1354 Changes in version 0.0.3 - 2004-03-26
1355 o Warn and fail if server chose a nickname with illegal characters
1356 o Port to Solaris and Sparc:
1357 - include missing header fcntl.h
1358 - have autoconf find -lsocket -lnsl automatically
1359 - deal with hardware word alignment
1360 - make uname() work (solaris has a different return convention)
1361 - switch from using signal() to sigaction()
1362 o Preliminary work on reputation system:
1363 - Keep statistics on success/fail of connect attempts; they're published
1364 by kill -USR1 currently.
1365 - Add a RunTesting option to try to learn link state by creating test
1366 circuits, even when SocksPort is off.
1367 - Remove unused open circuits when there are too many.
1370 Changes in version 0.0.2 - 2004-03-19
1371 - Include strlcpy and strlcat for safer string ops
1372 - define INADDR_NONE so we compile (but still not run) on solaris
1375 Changes in version 0.0.2pre27 - 2004-03-14
1377 - Allow internal tor networks (we were rejecting internal IPs,
1378 now we allow them if they're set explicitly).
1379 - And fix a few endian issues.
1382 Changes in version 0.0.2pre26 - 2004-03-14
1384 - If a stream times out after 15s without a connected cell, don't
1385 try that circuit again: try a new one.
1386 - Retry streams at most 4 times. Then give up.
1387 - When a dirserver gets a descriptor from an unknown router, it
1388 logs its fingerprint (so the dirserver operator can choose to
1389 accept it even without mail from the server operator).
1390 - Inform unapproved servers when we reject their descriptors.
1391 - Make tor build on Windows again. It works as a client, who knows
1393 - Clearer instructions in the torrc for how to set up a server.
1394 - Be more efficient about reading fd's when our global token bucket
1395 (used for rate limiting) becomes empty.
1397 - Stop asserting that computers always go forward in time. It's
1399 - When we sent a cell (e.g. destroy) and then marked an OR connection
1400 expired, we might close it before finishing a flush if the other
1401 side isn't reading right then.
1402 - Don't allow dirservers to start if they haven't defined
1404 - We were caching transient dns failures. Oops.
1405 - Prevent servers from publishing an internal IP as their address.
1406 - Address a strcat vulnerability in circuit.c
1409 Changes in version 0.0.2pre25 - 2004-03-04
1411 - Put the OR's IP in its router descriptor, not its fqdn. That way
1412 we'll stop being stalled by gethostbyname for nodes with flaky dns,
1415 - If the user typed in an address that didn't resolve, the server
1419 Changes in version 0.0.2pre24 - 2004-03-03
1421 - Fix an assertion failure in dns.c, where we were trying to dequeue
1422 a pending dns resolve even if it wasn't pending
1423 - Fix a spurious socks5 warning about still trying to write after the
1424 connection is finished.
1425 - Hold certain marked_for_close connections open until they're finished
1426 flushing, rather than losing bytes by closing them too early.
1427 - Correctly report the reason for ending a stream
1428 - Remove some duplicate calls to connection_mark_for_close
1429 - Put switch_id and start_daemon earlier in the boot sequence, so it
1430 will actually try to chdir() to options.DataDirectory
1431 - Make 'make test' exit(1) if a test fails; fix some unit tests
1432 - Make tor fail when you use a config option it doesn't know about,
1433 rather than warn and continue.
1434 - Make --version work
1435 - Bugfixes on the rpm spec file and tor.sh, so it's more up to date
1438 Changes in version 0.0.2pre23 - 2004-02-29
1440 - Print a statement when the first circ is finished, so the user
1442 - If a relay cell is unrecognized at the end of the circuit,
1443 send back a destroy. (So attacks to mutate cells are more
1445 - New config option 'excludenodes' to avoid certain nodes for circuits.
1446 - When it daemonizes, it chdir's to the DataDirectory rather than "/",
1447 so you can collect coredumps there.
1449 - Fix a bug in tls flushing where sometimes data got wedged and
1450 didn't flush until more data got sent. Hopefully this bug was
1451 a big factor in the random delays we were seeing.
1452 - Make 'connected' cells include the resolved IP, so the client
1453 dns cache actually gets populated.
1454 - Disallow changing from ORPort=0 to ORPort>0 on hup.
1455 - When we time-out on a stream and detach from the circuit, send an
1456 end cell down it first.
1457 - Only warn about an unknown router (in exitnodes, entrynodes,
1458 excludenodes) after we've fetched a directory.
1461 Changes in version 0.0.2pre22 - 2004-02-26
1463 - Servers publish less revealing uname information in descriptors.
1464 - More memory tracking and assertions, to crash more usefully when
1466 - If the default torrc isn't there, just use some default defaults.
1467 Plus provide an internal dirservers file if they don't have one.
1468 - When the user tries to use Tor as an http proxy, give them an http
1469 501 failure explaining that we're a socks proxy.
1470 - Dump a new router.desc on hup, to help confused people who change
1471 their exit policies and then wonder why router.desc doesn't reflect
1473 - Clean up the generic tor.sh init script that we ship with.
1475 - If the exit stream is pending on the resolve, and a destroy arrives,
1476 then the stream wasn't getting removed from the pending list. I
1477 think this was the one causing recent server crashes.
1478 - Use a more robust poll on OSX 10.3, since their poll is flaky.
1479 - When it couldn't resolve any dirservers, it was useless from then on.
1480 Now it reloads the RouterFile (or default dirservers) if it has no
1482 - Move the 'tor' binary back to /usr/local/bin/ -- it turns out
1483 many users don't even *have* a /usr/local/sbin/.
1486 Changes in version 0.0.2pre21 - 2004-02-18
1488 - There's a ChangeLog file that actually reflects the changelog.
1489 - There's a 'torify' wrapper script, with an accompanying
1490 tor-tsocks.conf, that simplifies the process of using tsocks for
1491 tor. It even has a man page.
1492 - The tor binary gets installed to sbin rather than bin now.
1493 - Retry streams where the connected cell hasn't arrived in 15 seconds
1494 - Clean up exit policy handling -- get the default out of the torrc,
1495 so we can update it without forcing each server operator to fix
1497 - Allow imaps and pop3s in default exit policy
1499 - Prevent picking middleman nodes as the last node in the circuit
1502 Changes in version 0.0.2pre20 - 2004-01-30
1504 - We now have a deb package, and it's in debian unstable. Go to
1506 - I've split the TotalBandwidth option into BandwidthRate (how many
1507 bytes per second you want to allow, long-term) and
1508 BandwidthBurst (how many bytes you will allow at once before the cap
1509 kicks in). This better token bucket approach lets you, say, set
1510 BandwidthRate to 10KB/s and BandwidthBurst to 10MB, allowing good
1511 performance while not exceeding your monthly bandwidth quota.
1512 - Push out a tls record's worth of data once you've got it, rather
1513 than waiting until you've read everything waiting to be read. This
1514 may improve performance by pipelining better. We'll see.
1515 - Add an AP_CONN_STATE_CONNECTING state, to allow streams to detach
1516 from failed circuits (if they haven't been connected yet) and attach
1518 - Expire old streams that haven't managed to connect. Some day we'll
1519 have them reattach to new circuits instead.
1522 - Fix several memory leaks that were causing servers to become bloated
1524 - Fix a few very rare assert triggers. A few more remain.
1525 - Setuid to User _before_ complaining about running as root.
1528 Changes in version 0.0.2pre19 - 2004-01-07
1530 - Fix deadlock condition in dns farm. We were telling a child to die by
1531 closing the parent's file descriptor to him. But newer children were
1532 inheriting the open file descriptor from the parent, and since they
1533 weren't closing it, the socket never closed, so the child never read
1534 eof, so he never knew to exit. Similarly, dns workers were holding
1535 open other sockets, leading to all sorts of chaos.
1536 - New cleaner daemon() code for forking and backgrounding.
1537 - If you log to a file, it now prints an entry at the top of the
1538 logfile so you know it's working.
1539 - The onionskin challenge length was 30 bytes longer than necessary.
1540 - Started to patch up the spec so it's not quite so out of date.
1543 Changes in version 0.0.2pre18 - 2004-01-02
1545 - Fix endian issues with the 'integrity' field in the relay header.
1546 - Fix a potential bug where connections in state
1547 AP_CONN_STATE_CIRCUIT_WAIT might unexpectedly ask to write.
1550 Changes in version 0.0.2pre17 - 2003-12-30
1552 - Made --debuglogfile (or any second log file, actually) work.
1553 - Resolved an edge case in get_unique_circ_id_by_conn where a smart
1554 adversary could force us into an infinite loop.
1557 - Each onionskin handshake now includes a hash of the computed key,
1558 to prove the server's identity and help perfect forward secrecy.
1559 - Changed cell size from 256 to 512 bytes (working toward compatibility
1561 - Changed cell length to 2 bytes, and moved it to the relay header.
1562 - Implemented end-to-end integrity checking for the payloads of
1564 - Separated streamid from 'recognized' (otherwise circuits will get
1565 messed up when we try to have streams exit from the middle). We
1566 use the integrity-checking to confirm that a cell is addressed to
1568 - Randomize the initial circid and streamid values, so an adversary who
1569 breaks into a node can't learn how many circuits or streams have
1573 Changes in version 0.0.2pre16 - 2003-12-14
1575 - Fixed a bug that made HUP trigger an assert
1576 - Fixed a bug where a circuit that immediately failed wasn't being
1577 counted as a failed circuit in counting retries.
1580 - Now we close the circuit when we get a truncated cell: otherwise we're
1581 open to an anonymity attack where a bad node in the path truncates
1582 the circuit and then we open streams at him.
1583 - Add port ranges to exit policies
1584 - Add a conservative default exit policy
1585 - Warn if you're running tor as root
1586 - on HUP, retry OR connections and close/rebind listeners
1587 - options.EntryNodes: try these nodes first when picking the first node
1588 - options.ExitNodes: if your best choices happen to include any of
1589 your preferred exit nodes, you choose among just those preferred
1591 - options.ExcludedNodes: nodes that are never picked in path building
1594 Changes in version 0.0.2pre15 - 2003-12-03
1595 o Robustness and bugfixes:
1596 - Sometimes clients would cache incorrect DNS resolves, which would
1597 really screw things up.
1598 - An OP that goes offline would slowly leak all its sockets and stop
1600 - A wide variety of bugfixes in exit node selection, exit policy
1601 handling, and processing pending streams when a new circuit is
1603 - Pick nodes for a path only from those the directory says are up
1604 - Choose randomly from all running dirservers, not always the first one
1605 - Increase allowed http header size for directory fetch.
1606 - Stop writing to stderr (if we're daemonized it will be closed).
1607 - Enable -g always, so cores will be more useful to me.
1608 - Switch "-lcrypto -lssl" to "-lssl -lcrypto" for broken distributions.
1611 - Wrote a man page. It lists commonly used options.
1614 - Change default loglevel to warn.
1615 - Make PidFile default to null rather than littering in your CWD.
1616 - OnionRouter config option is now obsolete. Instead it just checks
1618 - Moved to a single unified torrc file for both clients and servers.
1621 Changes in version 0.0.2pre14 - 2003-11-29
1622 o Robustness and bugfixes:
1623 - Force the admin to make the DataDirectory himself
1624 - to get ownership/permissions right
1625 - so clients no longer make a DataDirectory and then never use it
1626 - fix bug where a client who was offline for 45 minutes would never
1627 pull down a directory again
1628 - fix (or at least hide really well) the dns assert bug that was
1629 causing server crashes
1630 - warnings and improved robustness wrt clockskew for certs
1631 - use the native daemon(3) to daemonize, when available
1632 - exit if bind() fails
1633 - exit if neither socksport nor orport is defined
1634 - include our own tor_timegm (Win32 doesn't have its own)
1635 - bugfix for win32 with lots of connections
1636 - fix minor bias in PRNG
1637 - make dirserver more robust to corrupt cached directory
1640 - Wrote the design document (woo)
1642 o Circuit building and exit policies:
1643 - Circuits no longer try to use nodes that the directory has told them
1645 - Exit policies now support bitmasks (18.0.0.0/255.0.0.0) and
1646 bitcounts (18.0.0.0/8).
1647 - Make AP connections standby for a circuit if no suitable circuit
1648 exists, rather than failing
1649 - Circuits choose exit node based on addr/port, exit policies, and
1650 which AP connections are standing by
1651 - Bump min pathlen from 2 to 3
1652 - Relay end cells have a payload to describe why the stream ended.
1653 - If the stream failed because of exit policy, try again with a new
1655 - Clients have a dns cache to remember resolved addresses.
1656 - Notice more quickly when we have no working circuits
1659 - APPort is now called SocksPort
1660 - SocksBindAddress, ORBindAddress, DirBindAddress let you configure
1662 - RecommendedVersions is now a config variable rather than
1663 hardcoded (for dirservers)
1664 - Reloads config on HUP
1665 - Usage info on -h or --help
1666 - If you set User and Group config vars, it'll setu/gid to them.
1668 Changes in version 0.0.2pre13 - 2003-10-19
1669 o General stability:
1670 - SSL_write no longer fails when it returns WANTWRITE and the number
1671 of bytes in the buf has changed by the next SSL_write call.
1672 - Fix segfault fetching directory when network is down
1673 - Fix a variety of minor memory leaks
1674 - Dirservers reload the fingerprints file on HUP, so I don't have
1675 to take down the network when I approve a new router
1676 - Default server config file has explicit Address line to specify fqdn
1679 - Buffers grow and shrink as needed (Cut process size from 20M to 2M)
1680 - Make listener connections not ever alloc bufs
1682 o Autoconf improvements:
1683 - don't clobber an external CFLAGS in ./configure
1684 - Make install now works
1685 - create var/lib/tor on make install
1686 - autocreate a tor.sh initscript to help distribs
1687 - autocreate the torrc and sample-server-torrc with correct paths
1689 o Log files and Daemonizing now work:
1690 - If --DebugLogFile is specified, log to it at -l debug
1691 - If --LogFile is specified, use it instead of commandline
1692 - If --RunAsDaemon is set, tor forks and backgrounds on startup
