  48. - shipping Tor with its own integrated allocator.
  49. N - Write a draft research proposal for how to safely collect and
  50. aggregate some GeoIP data from non-bridge entry nodes, or conclude
  51. that we don't know how to do it safely while still being useful
  52. and explain why.

  79. ? - Brainstorm about safe but effective ways for vidalia to
  80. auto-update its user's bridges via Tor in the background.

  89. - spoof the cipher suites
  90. - spoof the extensions list
  91. - red-team testing (a.k.a, look at a packet dump and compare),
  92. - investigate the feasibility of handing connections off to a
  93. local apache if they don't look like Tor or if they don't
  94. portknock or whatever.
  95. R - Get closer to downloading far fewer descriptors
  96. - Instrument the code to track how many descriptors we download vs how
  97. many times we extend a circuit.
  98. - Write a proposal for how to fetch far fewer descriptors; assess
  99. anonymity attacks, like from looking at the size of the
  100. descriptor you fetch.
  101. I - Translation portal
  102. - Torbutton webpage
  103. o Torbrowser webpage

  106. - August
  107. I - Auto update
  108. o Vidalia learns when Tor thinks it should be updated
  109. R - Tor status events should suggest a new version to switch to
  110. I - Figure out a good PKI, document the design, assess security issues:
  111. "write a proposal"
  112. - Vidalia fetches the new one via Tor when possible, but fetches
  113. it without Tor "when necessary", whatever that means.
  114. - Give an interface for notifying the user, and letting her
  115. decide to fetch and decide to swap out the old Tor for the new.
  116. - Do the same for Polipo
  117. - and for Vidalia itself
  118. =======================================================================
  119. For Tor 0.2.0.x-rc:
  120. R - Figure out the autoconf problem with adding a fallback consensus.
  121. R - add a geoip file
  122. W - figure out license
  123. R - let bridges set relaybandwidthrate as low as 5kb
  124. R - bug: if we launch using bridges, and then stop using bridges, we
  125. still have our bridges in our entryguards section, and may use them.
  126. . make it easier to set up a private tor network on your own computer
  127. is very hard.
  128. R . FAQ entry which is wrong
  129. o Make BEGIN_DIR mandatory for asking questions of bridge authorities?
  130. (but only for bridge descriptors. not for ordinary cache stuff.)
  131. o Implement connection_dir_is_encrypted().
  132. o set up a filter to not answer any bridge descriptors on a
  133. non-encrypted request
  134. o write a tor-gencert man page
  135. N . geoip caching and publishing for bridges
  136. d Track consecutive time up, not time since last-forgotten IP.
  137. - Mention in dir-spec.txt
  138. - Mention in control-spec.txt
  139. D have normal relays report geoip stats too.
  140. D different thresholds for bridges than for normal relays.
  141. o bridge relays round geoip stats *up*, not down.
  142. R - bridge communities
  143. . spec
  144. . deploy
  145. - man page entries for Alternate*Authority config options
  146. Things we'd like to do in 0.2.0.x:
  147. o if we notice a cached-status directory and we're not serving v2 dir
  148. info and it's old enough, delete it.
  149. o same with cached-routers*.
  150. N - document the "3/4 and 7/8" business in the clients fetching consensus
  151. documents timeline.
  152. R - then document the bridge user download timeline.
  153. N - Before the feature freeze:
  154. - 105+TLS, if possible.
  155. . TLS backend work
  156. . Enable.
  157. - Test
  158. o Verify version negotiation on client
  159. o Verify version negotiation on server
  160. o Verify that client->server connection becomes open
  161. - Verify that server->server connection becomes open and
  162. authenticated.
  163. - Verify that initiator sends no cert in first stage of TLS
  164. handshake.
  165. - NETINFO fallout
  166. - Don't extend a circuit over a noncanonical connection with
  167. mismatched address.
  168. - Learn our outgoing IP address from netinfo cells?
  169. - Bugs.
  170. - Bug reports Roger has heard along the way that don't have enough
  171. details/attention to solve them yet.
  172. - arma noticed that when his network went away and he tried
  173. a new guard node and the connect() syscall failed to it,
  174. the guard wasn't being marked as down. 0.2.0.x.
  175. - after being without network for 12 hours, arma's tor decided
  176. it couldn't fetch any network statuses, and never tried again
  177. even when the network came back and arma clicked on things.
  178. also 0.2.0.
  179. R - for above two, roger should turn them into flyspray entry.
  180. - Proposals:
  181. o 101: Voting on the Tor Directory System (plus 103)
  182. N - Use if-modified-since on consensus download
  183. - Controller support
  184. D GETINFO to get consensus
  185. N - Event when new consensus arrives
  186. . 111: Prioritize local traffic over relayed.
  187. R - Merge into tor-spec.txt.
  188. - Refactoring:
  189. . Make cells get buffered on circuit, not on the or_conn.
  190. . Switch to pool-allocation for cells?
  191. N - Benchmark pool-allocation vs straightforward malloc.
  192. N - Adjust memory allocation logic in pools to favor a little less
  193. slack memory.
  194. . Remove socketpair-based bridges conns, and the word "bridge". (Use
  195. shared (or connected) buffers for communication, rather than sockets.)
  196. . Implement
  197. N - Handle rate-limiting on directory writes to linked directory
  198. connections in a more sensible manner.
  199. Nick thinks he did this already?
  200. N - Find more ways to test this.
  201. (moria doesn't rate limit, so testing on moria not so good.)
  202. - Documentation
  203. - HOWTO for DNSPort. See tup's wiki page.
  204. . Document transport and natdport in a good HOWTO.
  205. N - Quietly document NT Service options: revise (or create) FAQ entry
  206. R - make sure you solved bug 556
  207. P - Make documentation realize that location of system configuration file
  208. will depend on location of system defaults, and isn't always /etc/torrc.
  209. P - Figure out why dll's compiled in mingw don't work right in WinXP.
  210. P - create a "make win32-bundle" for vidalia-privoxy-tor-torbutton bundle
  211. =======================================================================
  212. Planned for 0.2.1.x:
  213. - Things that have been bugging Nick
  214. - Make better use of multi-core machines: Do AES crypto and
  215. compression in worker threads
  216. - Maybe use jemalloc from freebsd via firefox 3, once its windows
  217. and osx ports are more mature.
  218. - MMap the cached-descriptors.new file as well as the regular ones
  219. - Actually use SSL_shutdown to close our TLS connections.
  220. - Refactor the HTTP logic so the functions aren't so large.
  221. - Get a "use less buffer ram" patch into openssl.
  222. - Get IOCP patch into libevent
  223. - Use libevent's evdns code where applicable.
  224. - Refactor buf_read and buf_write to have sensible ways to return
  225. error codes after partial writes
  226. - Improve unit test coverage
  227. - Logging domains.
  228. - get rid of the v1 directory stuff (making, serving, and caching).
  229. - perhaps replace it with a "this is a tor server" stock webpage.
  230. - even clients run rep_hist_load_mtbf_data(). this wastes memory.
  231. - steven's plan for replacing check.torproject.org with a built-in
  232. answer by tor itself.
  233. - a status event for when tor decides to stop fetching directory info
  234. if the client hasn't clicked recently: then make the onion change too.
  235. - bridge communities with local bridge authorities:
  236. - clients who have a password configured decide to ask their bridge
  237. authority for a networkstatus
  238. - be able to have bridges that aren't in your torrc. save them in
  239. state file, etc.
  240. - router_choose_random_node() has a big pile of args. make it "flags".
  241. - Consider if we can solve: the Tor client doesn't know what flags
  242. its bridge has (since it only gets the descriptor), so it can't
  243. make decisions based on Fast or Stable.
  244. - anonymity concern: since our is-consensus-fresh-enough check is
  245. sloppy so clients will actually work when a consensus wasn't formed,
  246. does that mean that if users are idle for 5 hours and then click on
  247. something, we will immediately use the old descriptors we've got,
  248. while we try fetching the newer descriptors?
  249. related to bug 401.
  250. . Finish path-spec.txt
  251. - More prominently, we should have a recommended apps list.
  252. - recommend pidgin (gaim is renamed)
  253. - unrecommend IE because of ftp:// bug.
  254. - we should add a preamble to tor-design saying it's out of date.
  255. - Refactor networkstatus generation:
  256. - Include "v" line in getinfo values.
  257. - config option __ControllerLimit that hangs up if there are a limit
  258. of controller connections already.
  259. - Features (other than bridges):
  260. - Audit how much RAM we're using for buffers and cell pools; try to
  261. trim down a lot.
  262. - Base relative control socket paths on datadir.
  263. - Make TrackHostExits expire TrackHostExitsExpire seconds after their
  264. *last* use, not their *first* use.
  265. - Plan a switch to polipo. Perhaps we'll offer two http proxies in
  266. the future.
  267. - Consider creating special Tor-Polipo-Vidalia test packages,
  268. requested by Dmitri Vitalev (does torbrowser meet this need?)
  269. - Create packages for Nokia 800, requested by Chris Soghoian
  270. - mirror tor downloads on (via) tor dir caches
  271. . spec
  272. - deploy
  273. - interface for letting soat modify flags that authorities assign
  274. . spec
  275. - proposal 118 if feasible and obvious
  276. - Maintain a skew estimate and use ftime consistently.
  277. - Tor logs the libevent version on startup, for debugging purposes.
  278. This is great. But it does this before configuring the logs, so
  279. it only goes to stdout and is then lost.
  280. - Deprecations:
  281. - can we deprecate 'getinfo network-status'?
  282. - can we deprecate the FastFirstHopPK config option?
  283. - Bridges:
  284. . Bridges users (rudimentary version)
  285. . Ask all directory questions to bridge via BEGIN_DIR.
  286. - use the bridges for dir fetches even when our dirport is open.
  287. - drop 'authority' queries if they're to our own identity key; accept
  288. them otherwise.
  289. - give extend_info_t a router_purpose again
  290. d Limit to 2 dir, 2 OR, N SOCKS connections per IP.
  291. - Or maybe close connections from same IP when we get a lot from one.
  292. - Or maybe block IPs that connect too many times at once.
  293. - Do TLS connection rotation more often than "once a week" in the
  294. extra-stable case.
  295. - Streamline how we pick entry nodes: Make choose_random_entry() have
  296. less magic and less control logic.
  297. - when somebody uses the controlport as an http proxy, give them
  298. a "tor isn't an http proxy" error too like we do for the socks port.
  299. - we try to build 4 test circuits to break them over different
  300. servers. but sometimes our entry node is the same for multiple
  301. test circuits. this defeats the point.
  302. - enforce a lower limit on MaxCircuitDirtiness and CircuitBuildTimeout.
  303. - configurable timestamp granularity. defaults to 'seconds'.
  304. - consider making 'safelogging' extend to info-level logs too.
  305. - we should consider a single config option TorPrivateNetwork that
  306. turns on all the config options for running a private test tor
  307. network. having to keep updating all the tools, and the docs,
  308. just isn't working.
  309. - consider whether a single Guard flag lets us distinguish between
  310. "was good enough to be a guard when we picked it" and "is still
  311. adequate to be used as a guard even after we've picked it". We should
  312. write a real proposal for this.
  313. - switch out privoxy in the bundles and replace it with polipo.
  314. - make the new tls handshake blocking-resistant.
  315. - figure out some way to collect feedback about what countries are using
  316. bridges, in a way that doesn't screw anonymity too much.
  317. - let tor dir mirrors proxy connections to the tor download site, so
  318. if you know a bridge you can fetch the tor software.
  319. - more strategies for distributing bridge addresses in a way that
  320. doesn't rely on knowing somebody who runs a bridge for you.
  321. - A way to adjust router status flags from the controller. (How do we
  322. prevent the authority from clobbering them soon afterward?)
  323. - Bridge authorities should do reachability testing but only on the
  324. purpose==bridge descriptors they have.
  325. - Clients should estimate their skew as median of skew from servers
  326. over last N seconds.
  327. - Investigate RAM use in Tor servers.
  328. - Start on the WSAENOBUFS solution.
  329. - Start on Windows auto-update for Tor
  330. - Stuff that weasel wants:
  331. - Make Tor able to chroot itself
  332. o allow it to load an entire config file from control interface
  333. - document LOADCONF
  334. - log rotation (and FD passing) via control interface
  335. - chroot yourself, including inhibit trying to read config file
  336. and reopen logs, unless they are under datadir.
  337. Deferred from 0.2.0.x:
  338. - Proposals
  339. - 113: Simplifying directory authority administration
  340. - 110: prevent infinite-length circuits (phase one)
  341. - 118: Listen on and advertise multiple ports:
  342. - Tor should be able to have a pool of outgoing IP addresses that it is
  343. able to rotate through. (maybe. Possible overlap with proposal 118.)
  344. - config option to publish what ports you listen on, beyond
  345. ORPort/DirPort. It should support ranges and bit prefixes (?) too.
  346. (This is very similar to proposal 118.)
  347. - 117: IPv6 Exits
  348. - Internal code support for ipv6:
  349. o Clone ipv6 functions (inet_ntop, inet_pton) where they don't exist.
  350. - Most address variables need to become tor_addr_t
  351. - Teach resolving code how to handle ipv6.
  352. - Teach exit policies about ipv6 (consider ipv4/ipv6 interaction!)
  353. - Features
  354. - Let controller set router flags for authority to transmit, and for
  355. client to use.
  356. - add an 'exit-address' line in the descriptor for servers that exit
  357. from something that isn't their published address.
  358. - More work on AvoidDiskWrites?
  359. - Features
  360. - Make a TCP DNSPort
  361. - Protocol work
  362. - MAYBE kill stalled circuits rather than stalled connections. This is
  363. possible thanks to cell queues, but we need to consider the anonymity
  364. implications.
  365. - Implement TLS shutdown properly when possible.
  366. - Bugs
  367. - If the client's clock is too far in the past, it will drop (or just not
  368. try to get) descriptors, so it'll never build circuits.
  369. - Refactoring
  370. - Make resolves no longer use edge_connection_t unless they are actually
  371. _on_ a socks connection: have edge_connection_t and (say)
  372. dns_request_t both extend an edge_stream_t, and have p_streams and
  373. n_streams both be linked lists of edge_stream_t.
  374. - Generate torrc.{complete|sample}.in, tor.1.in, the HTML manual, and the
  375. online config documentation from a single source.
  376. - Move all status info out of routerinfo into local_routerstatus. Make
  377. "who can change what" in local_routerstatus explicit. Make
  378. local_routerstatus (or equivalent) subsume all places to go for "what
  379. router is this?"
  380. - Blocking/scanning-resistance
  381. - It would be potentially helpful to respond to https requests on
  382. the OR port by acting like an HTTPS server.
  383. - Do we want to maintain our own set of entryguards that we use as
  384. next hop after the bridge? Open research question; let's say no
  385. for 0.2.0 unless we learn otherwise.
  386. - Some mechanism for specifying that we want to stop using a cached
  387. bridge.
  388. - Build:
  389. - Detect correct version of libraries from autoconf script.
  390. =======================================================================
  391. Future versions:
  392. - deprecate router_digest_is_trusted_dir() in favor of
  393. router_get_trusteddirserver_by_digest()
  394. - See also Flyspray tasks.
  395. - See also all OPEN/ACCEPTED proposals.
  396. - See also all items marked XXXX and FFFF in the code.
  397. - Protocol:
  398. - Our current approach to block attempts to use Tor as a single-hop proxy
  399. is pretty lame; we should get a better one.
  400. - Allow small cells and large cells on the same network?
  401. - Cell buffering and resending. This will allow us to handle broken
  402. circuits as long as the endpoints don't break, plus will allow
  403. connection (tls session key) rotation.
  404. - Implement Morphmix, so we can compare its behavior, complexity,
  405. etc. But see paper breaking morphmix.
  406. - Other transport. HTTP, udp, rdp, airhook, etc. May have to do our own
  407. link crypto, unless we can bully DTLS into it.
  408. - Need a relay teardown cell, separate from one-way ends.
  409. (Pending a user who needs this)
  410. - Handle half-open connections: right now we don't support all TCP
  411. streams, at least according to the protocol. But we handle all that
  412. we've seen in the wild.
  413. (Pending a user who needs this)
  414. - Directory system
  415. - BEGIN_DIR items
  416. X turn the received socks addr:port into a digest for setting .exit
  417. - handle connect-dir streams that don't have a chosen_exit_name set.
  418. - Have a "Faster" status flag that means it. Fast2, Fast4, Fast8?
  419. - Add an option (related to AvoidDiskWrites) to disable directory
  420. caching. (Is this actually a good idea??)
  421. - Add d64 and fp64 along-side d and fp so people can paste status
  422. entries into a url. since + is a valid base64 char, only allow one
  423. at a time. Consider adding to controller as well.
  424. - Some back-out mechanism for auto-approval on authorities
  425. - a way of rolling back approvals to before a timestamp
  426. - Consider minion-like fingerprint file/log combination.
  427. - Have new people be in limbo and need to demonstrate usefulness
  428. before we approve them.
  429. - Hidden services:
  430. - Standby/hotswap/redundant hidden services.
  431. . Update the hidden service stuff for the new dir approach. (Much
  432. of this will be superseded by 114.)
  433. - switch to an ascii format, maybe sexpr?
  434. - authdirservers publish blobs of them.
  435. - other authdirservers fetch these blobs.
  436. - hidserv people have the option of not uploading their blobs.
  437. - you can insert a blob via the controller.
  438. - and there's some amount of backwards compatibility.
  439. - teach clients, intro points, and hidservs about auth mechanisms.
  440. - come up with a few more auth mechanisms.
  441. - auth mechanisms to let hidden service midpoint and responder filter
  442. connection requests.
  443. - Let each hidden service (or other thing) specify its own
  444. OutboundBindAddress?
  445. - Hidserv offerers shouldn't need to define a SocksPort
  446. - Server operation
  447. X When we notice a 'Rejected: There is already a named server with
  448. this nickname' message... or maybe instead when we see in the
  449. networkstatuses that somebody else is Named with the name we
  450. want: warn the user, send a STATUS_SERVER message, and fall back
  451. to unnamed.
  452. - If the server is spewing complaints about raising your ulimit -n,
  453. we should add a note about this to the server descriptor so other
  454. people can notice too.
  455. - When we hit a funny error from a dir request (eg 403 forbidden),
  456. but tor is working and happy otherwise, and we haven't seen many
  457. such errors recently, then don't warn about it.
  458. - Controller
  459. - Implement missing status events and accompanying getinfos
  460. - DIR_REACHABLE
  461. - BAD_DIR_RESPONSE (Unexpected directory response; maybe we're behind
  462. a firewall.)
  463. - BAD_PROXY (Bad http or https proxy)
  464. - UNRECOGNIZED_ROUTER (a nickname we asked for is unavailable)
  465. - Status events related to hibernation
  466. - something about failing to parse our address?
  467. from resolve_my_address() in config.c
  468. - sketchy OS, sketchy threading
  469. - too many onions queued: threading problems or slow CPU?
  470. - Implement missing status event fields:
  471. - TIMEOUT on CHECKING_REACHABILITY
  472. - GETINFO status/client, status/server, status/general: There should be
  473. some way to learn which status events are currently "in effect."
  474. We should specify which these are, what format they appear in, and so
  475. on.
  476. - More information in events:
  477. - Include bandwidth breakdown by conn->type in BW events.
  478. - Change circuit status events to give more details, like purpose,
  479. whether they're internal, when they become dirty, when they become
  480. too dirty for further circuits, etc.
  481. - Change stream status events analogously.
  482. - Expose more information via getinfo:
  483. - import and export rendezvous descriptors
  484. - Review all static fields for additional candidates
  485. - Allow EXTENDCIRCUIT to unknown server.
  486. - We need some way to adjust server status, and to tell tor not to
  487. download directories/network-status, and a way to force a download.
  488. - Make everything work with hidden services
  489. - Performance/resources
  490. - per-conn write buckets
  491. - separate config options for read vs write limiting
  492. (It's hard to support read > write, since we need better
  493. congestion control to avoid overfull buffers there. So,
  494. defer the whole thing.)
  495. - Look into pulling serverdescs off buffers as they arrive.
  496. - Rate limit exit connections to a given destination -- this helps
  497. us play nice with websites when Tor users want to crawl them; it
  498. also introduces DoS opportunities.
  499. - Consider truncating rather than destroying failed circuits,
  500. in order to save the effort of restarting. There are security
  501. issues here that need thinking, though.
  502. - Handle full buffers without totally borking
  503. - Rate-limit OR and directory connections overall and per-IP and
  504. maybe per subnet.
  505. - Misc
  506. - Hold-open-until-flushed now works by accident; it should work by
  507. design.
  508. - Display the reasons in 'destroy' and 'truncated' cells under
  509. some circumstances?
  510. - Make router_is_general_exit() a bit smarter once we're sure what
  511. it's for.
  512. - Automatically determine what ports are reachable and start using
  513. those, if circuits aren't working and it's a pattern we
  514. recognize ("port 443 worked once and port 9001 keeps not
  515. working").
  516. - Security
  517. - some better fix for bug #516?
  518. - don't do dns hijacking tests if we're reject *:* exit policy?
  519. (deferred until 0.1.1.x is less common)
  520. - Directory guards
  521. - Mini-SoaT:
  522. - Servers might check certs for known-good ssl websites, and if
  523. they come back self-signed, declare themselves to be
  524. non-exits. Similar to how we test for broken/evil dns now.
  525. - Authorities should try using exits for http to connect to some
  526. URLS (specified in a configuration file, so as not to make the
  527. List Of Things Not To Censor completely obvious) and ask them
  528. for results. Exits that don't give good answers should have
  529. the BadExit flag set.
  530. - Alternatively, authorities should be able to import opinions
  531. from Snakes on a Tor.
  532. - More consistent error checking in router_parse_entry_from_string().
  533. I can say "banana" as my bandwidthcapacity, and it won't even squeak.
  534. - Bind to random port when making outgoing connections to Tor servers,
  535. to reduce remote sniping attacks.
  536. - Audit everything to make sure rend and intro points are just as
  537. likely to be us as not.
  538. - Do something to prevent spurious EXTEND cells from making
  539. middleman nodes connect all over. Rate-limit failed
  540. connections, perhaps?
  541. - DoS protection: TLS puzzles, public key ops, bandwidth exhaustion.
  542. - Needs thinking
  543. - Now that we're avoiding exits when picking non-exit positions,
  544. we need to consider how to pick nodes for internal circuits. If
  545. we avoid exits for all positions, we skew the load balancing. If
  546. we accept exits for all positions, we leak whether it's an
  547. internal circuit at every step. If we accept exits only at the
  548. last hop, we reintroduce Lasse's attacks from the Oakland paper.
  549. - Windows server usability
  550. - Solve the ENOBUFS problem.
  551. - make tor's use of openssl operate on buffers rather than sockets,
  552. so we can make use of libevent's buffer paradigm once it has one.
  553. - make tor's use of libevent tolerate either the socket or the
  554. buffer paradigm; includes unifying the functions in connect.c.
  555. - We need a getrlimit equivalent on Windows so we can reserve some
  556. file descriptors for saving files, etc. Otherwise we'll trigger
  557. asserts when we're out of file descriptors and crash.
  558. - Merge code from Urz into libevent
  559. - Make Tor use evbuffers.
  560. - Documentation
  561. - a way to generate the website diagrams from source, so we can
  562. translate them as utf-8 text rather than with gimp. (svg? or
  563. imagemagick?)
  564. . Flesh out options_description array in src/or/config.c
  565. . multiple sample torrc files
  566. . figure out how to make nt service stuff work?
  567. . Document it.
  568. - Refactor tor man page to divide generally useful options from
  569. less useful ones?
  570. - Add a doxygen style checker to make check-spaces so nick doesn't drift
  571. too far from arma's undocumented styleguide. Also, document that
  572. styleguide in HACKING. (See r9634 for example.)
  573. - exactly one space at beginning and at end of comments, except i
  574. guess when there's line-length pressure.
  575. - if we refer to a function name, put a () after it.
  576. - only write <b>foo</b> when foo is an argument to this function.
  577. - doxygen comments must always end in some form of punctuation.
  578. - capitalize the first sentence in the doxygen comment, except
  579. when you shouldn't.
  580. - avoid spelling errors and incorrect comments. ;)
  581. - Packaging
  582. - The Debian package now uses --verify-config when (re)starting,
  583. to distinguish configuration errors from other errors. Perhaps
  584. the RPM and other startup scripts should too?
  585. - add a "default.action" file to the tor/vidalia bundle so we can
  586. fix the https thing in the default configuration:
  587. http://wiki.noreply.org/noreply/TheOnionRouter/TorFAQ#PrivoxyWeirdSSLPort
  588. - Related tools
  589. - Patch privoxy and socks protocol to pass strings to the browser.
  590. =======================================================================
  591. Documentation, non-version-specific.
  592. - Specs
  593. - Mark up spec; note unclear points about servers
  594. NR - write a spec appendix for 'being nice with tor'
  595. - Specify the keys and key rotation schedules and stuff
  596. - Mention controller libs someplace.
  597. - Remove need for HACKING file.
  598. - document http://wiki.noreply.org/noreply/TheOnionRouter/TransparentProxy on freebsd and osx
  599. P - figure out why x86_64 won't build rpms from tor.spec
  600. P - figure out rpm spec files for bundles of vidalia-tor-polipo
  601. P - figure out polipo install scripts for bundles of vidalia-tor-polipo on osx, win32
  602. - figure out selinux policy for tor
  603. P - change packaging system to more automated and specific for each
  604. platform, suggested by Paul Wouter
  605. P - Setup repos for redhat and suse rpms & start signing the rpms the
  606. way package management apps prefer
  607. Website:
  608. J . tor-in-the-media page
  609. - Which bundles include Torbutton? Change the docs/tor-doc-foo pages
  610. so they admit that Torbutton is in them too. Change the download
  611. page too.
  612. - The OS X bundle screenshots are from forever ago -- they don't
  613. include Torbutton, they still say it's tor.eff.org, etc.
  614. - Should we still be telling you how to use Safari on OS X for Tor,
  615. given all the holes that Torbutton-dev solves on Firefox?
  616. P - Figure out licenses for website material.
  617. (Phobos reccomends the Open Publication License with Option A at
  618. http://opencontent.org/openpub/)
  619. P - put the logo on the website, in source form, so people can put it on
  620. stickers directly, etc.
  621. P - put the source image for the stickers on the website, so people can
  622. print their own
  623. P - figure out a license for the logos and docs we publish (trademark
  624. figures into this)
  625. (Phobos reccomends the Open Publication License with Option A at
  626. http://opencontent.org/openpub/)
  627. R - make a page with the hidden service diagrams.
  628. P - ask Jan/Jens to be the translation coordinator? add to volunteer page.
  629. I - add a page for localizing all tor's components.
  630. - It would be neat if we had a single place that described _all_ the
  631. tor-related tools you can use, and what they give you, and how well they
  632. work. Right now, we don't give a lot of guidance wrt
  633. torbutton/foxproxy/privoxy/polipo in any consistent place.
  634. P - create a 'blog badge' for tor fans to link to and feature on their
  635. blogs. A sample can be found at http://interloper.org/tmp/tor/tor-button.png
  636. - Tor mirrors
  637. - make a mailing list with the mirror operators
  638. - make an automated tool to check /project/trace/ at mirrors to
  639. learn which ones are lagging behind.
  640. - auto (or manually) cull the mirrors that are broken; and
  641. contact their operator?
  642. - a set of instructions for mirror operators to make their apaches
  643. serve our charsets correctly, and bonus points for language
  644. negotiation.
  645. - figure out how to load-balance the downloads across mirrors?
  646. - ponder how to get users to learn that they should google for
  647. "tor mirrors" if the main site is blocked.
  648. - find a mirror volunteer to coordinate all of this
