* Make arguments to circuit_set_circid_orconn match the connection that is ↵Nick Mathewson2005-11-29
| | | | | | closing in circuit_about_to_close_connection. This accounts for our mysterious "arbitrary ram gets decremented!" bug. svn:r5465
* "How about 'never'? Does 'never' work for you?"Nick Mathewson2005-11-26
| | | | | | | | | | | | | | | | | Weasel says circuit_get_by_conn is his main timesink. Most of its users were just checking whether OR conns had circuits, so add a circuit count to OR conns, and check that. One was circuit_about_to_close_conn, which was doing an O(n^2) series of calls to get all circs on an OR conn, so make an O(n) function for that. Finally, circuit_get_by_edge_conn was using it as a sanity test that has been around for a while but never found any actualy insanity, so kill that. circuit_get_by_conn is finally dead, which is good, since it was never sane to begin with. svn:r5460
* Start the process of treating internal circuits and exit circuitsRoger Dingledine2005-11-25
| | | | | | | | | | | | | | | | | | | separately. It's important to keep them separate because internal circuits have their last hops picked like middle hops, rather than like exit hops. So exiting on them will break the user's expectations. - Stop cannibalizing internal circuits for general exits, and stop cannibalizing exit circuits for rendezvous stuff. - Don't let new exit streams attach to internal circuits. - When deciding if we have enough circuits for internal and for exit, don't count the wrong ones. - Treat predicted resolves as predicted port 80 exits. svn:r5457
* Recover better from TCP connections to Tor servers that are broken butRoger Dingledine2005-11-19
| | | | | | | | | | | | | | | | don't tell you (it happens!); and rotate TLS connections once a week. 1) If an OR conn becomes more than a week old, make it obsolete. 2) If it's obsolete and empty, kill it. 3) When an OR makes a second connection to you, allow it. 4) If we want to send a new create cell, but the best conn we've got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask for a new conn instead. 5) When we time out on circuit building on the first hop, make that connection obsolete. svn:r5429

| | | | | | | | node in mind, we weren't checking to see if that exit node was already present earlier in the circuit. oops. svn:r5357

* replace former relaunches of directory downloads with reset of failure count ↵Nick Mathewson2005-10-05
| | | | | | and relaunch of status downloads. Fix memory leak in trusted_dir_server_t. Reset "last download attempted" time when resetting failure counts. svn:r5195
* Note the two places where clients will still try to fetch old-style (v1) ↵Nick Mathewson2005-10-05
| | | | | | directory info. These should be fixed, I think. svn:r5193
* Check for named servers when looking them up by nickname;Nick Mathewson2005-10-04
| | | | | | | | | | | | | | | | | | | warn when we'recalling a non-named server by its nickname; don't warn twice about the same name. Fix a bug in routers_update_status_from_networkstatus that made nearly all clients never update routerinfo_t.is_named. Try to list MyFamily elements by key, not by nickname. Only warn about names that we generated ourself, or got from the local user. On TLS handshake, only check the other router's nickname against its expected nickname if is_named is set. svn:r5185
* Reformat inconsistent function declarations.Nick Mathewson2005-09-30
| | | | svn:r5160
* Implement exit enclaves: if we know an IP address for the destination,Roger Dingledine2005-08-15
| | | | | | | | | and there's a running Tor server at that address which allows exit to the destination, then extend the circuit to that exit first. Also, if the user asks for a .exit node, cannibalize general circs for it. svn:r4779
* predict required circuits better, with an eye toward makingRoger Dingledine2005-08-13
| | | | | | | hidden services faster on the service end. svn:r4772
* We weren't cannibilizing circuits correctly forRoger Dingledine2005-08-12
| | | | | | | | | CIRCUIT_PURPOSE_C_ESTABLISH_REND and CIRCUIT_PURPOSE_S_ESTABLISH_INTRO so we were being forced to build those from scratch. This should save us a bit of time. Also fixes bug 173. svn:r4763

* Logic to implement rendezvous/introduction via unknown servers.Nick Mathewson2005-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add a new extend_info_t datatype to hold information needed to extend a circuit (addr,port,keyid,onion_key). Use it in cpath and build_state. Make appropriate functions take or return it instead of routerinfo_t or keyid. - #if 0 needless check in circuit_get_by_edge_conn; if nobody triggers this error in 0.1.0.10, nobody will trigger it. - Implement new hidden service descriptor format, which contains "extend info" for introduction points, along with protocol version list. - Parse new format. - Generate new format - Cache old and new formats alongside each other. - Directories serve "old" format if asked in old way, "newest available" format if asked in new way. - Use new format to find introduction points if possible; otherwise fall back. Keep nickname lists and extendinfo lists in sync. - Tests for new format. - Implement new "v2" INTRODUCE cell format. - Accept new format - Use new format if we have a versioned service descriptor that says the server accepts the new format. - Add documentation for functions and data types. svn:r4506

* Rename circuit_get_by_stream to circuit_get_by_edge_conn, and actually start ↵Nick Mathewson2005-04-06

* when building testing circuits, always use middle hopsRoger Dingledine2005-04-01
| | | | | | | running at least 0.0.9.7 svn:r3966
* when the or-connect succeeded and the tls handshake succeededRoger Dingledine2005-04-01
| | | | | | | | | but we didn't like the result, we were closing the connection without sending any destroys back for the pending circuits. now send those destroys anyway; i hope this doesn't break too much. svn:r3951
* still publish your descriptor if orport is reachable but dirport isn'tRoger Dingledine2005-03-31
| | | | | | | | | when building testing circs for orport testing, require high-bandwidth nodes, so fewer circs fail. complain about unreachable orport separately from unreachable dirport. svn:r3935

* Implement controller's "extendcircuit" directive.Roger Dingledine2005-03-22
| | | | | | | | Also refactor circuit building so we plan the whole path ahead of time. svn:r3797
* Turn addr_policy_compare from a tristate to a quadstate; this should help ↵Nick Mathewson2005-03-19

| | | | svn:r3781
* Commit fixes for several pending tor core tasks: document all DOCDOCed ↵Nick Mathewson2005-03-17
| | | | | | functions; time out uncontrolled unattached streams; feed reasons to SOCKS5 (refactoring connection_ap_handshake_socks_reply in the process); change DirFetchPeriod/StatusFetchPeriod to have a special "Be smart" value. svn:r3769
* re-enable reachability testing stuff.Roger Dingledine2005-03-15
| | | | | | | | also, consider your ORPort reachable after you've processed a create cell from any non-local address. svn:r3763

| | | | svn:r3751
* Checkpoint in-progress fixes:Roger Dingledine2005-02-27
| | | | | | | | | | | | | Add 'testing' circuit purpose, for reachability testing. Notice when our IP changes, and reset stats. Try to pull down a directory via Tor to see if our DirPort is working. Try to extend a circuit back to us to see if our ORPort is working. Only publish a descriptor if they're both reachable. These mostly work, and I'd better get them in before I cause conflicts. svn:r3703
* Add a new AddressMap directive to rewrite incoming socks addresses.Roger Dingledine2005-02-22
| | | | | | | | | | Add a new TrackHostExits directive to trigger addressmaps for certain incoming socks addresses, for sites that break when your exit keeps changing. Redo the client-side dns cache so it's just an addressmap too. svn:r3641
* bugfix: tor-resolve requests were ignoring .exit if there wasRoger Dingledine2005-02-02

* define TOR_FRAGILE if you want tor to give you a core whenRoger Dingledine2005-02-01
| | | | | | | | something goes wrong. this should only be used by people actively tracking bugs. svn:r3487
* The crowning hidden-service patch: prefer non-internal circuitsRoger Dingledine2005-01-20
| | | | | | | | for normal connections, so we don't spend our internal circs on other stuff and not have them when we need them. svn:r3380
* Handle unavailable hidden services better. We try each intro pointRoger Dingledine2005-01-19
| | | | | | | | | | until none are left, then we try to refetch the descriptor. If it's the same one we had before, then close streams right then. Whenever a new stream arrives, even if it's right after, optimistically try refetching the descriptor, just in case. svn:r3379
