30 | * This is a bit confusing. | |
31 | * | |
32 | * Normal SNAC login goes like this: | |
33 | * - connect | |
34 | * - server sends flap version | |
35 | * - client sends flap version | |
36 | * - client sends screen name (17/6) | |
37 | * - server sends hash key (17/7) | |
38 | * - client sends auth request (17/2 -- aim_send_login) | |
39 | * - server yells | |
40 | * | |
41 | * XOR login (for ICQ) goes like this: | |
42 | * - connect | |
43 | * - server sends flap version | |
44 | * - client sends auth request which contains flap version (aim_send_login) | |
45 | * - server yells | |
46 | * | |
47 | * For the client API, we make them implement the most complicated version, | |
48 | * and for the simpler version, we fake it and make it look like the more | |
49 | * complicated process. | |
50 | * | |
51 | * This is done by giving the client a faked key, just so we can convince | |
52 | * them to call aim_send_login right away, which will detect the session | |
53 | * flag that says this is XOR login and ignore the key, sending an ICQ | |
54 | * login request instead of the normal SNAC one. | |
55 | * | |
56 | * As soon as AOL makes ICQ log in the same way as AIM, this is /gone/. | |
57 | * | |
58 | * XXX This may cause problems if the client relies on callbacks only | |
59 | * being called from the context of aim_rxdispatch()... | |

522 | * The Rate Limiting System, An Abridged Guide to Nonsense. | |
523 | * | |
524 | * OSCAR defines several 'rate classes'. Each class has seperate | |
525 | * rate limiting properties (limit level, alert level, disconnect | |
526 | * level, etc), and a set of SNAC family/type pairs associated with | |
527 | * it. The rate classes, their limiting properties, and the definitions | |
528 | * of which SNACs are belong to which class, are defined in the | |
529 | * Rate Response packet at login to each host. | |
530 | * | |
531 | * Logically, all rate offenses within one class count against further | |
532 | * offenses for other SNACs in the same class (ie, sending messages | |
533 | * too fast will limit the number of user info requests you can send, | |
534 | * since those two SNACs are in the same rate class). | |
535 | * | |
536 | * Since the rate classes are defined dynamically at login, the values | |
537 | * below may change. But they seem to be fairly constant. | |
538 | * | |
539 | * Currently, BOS defines five rate classes, with the commonly used | |
540 | * members as follows... | |
541 | * | |
542 | * Rate class 0x0001: | |
543 | * - Everything thats not in any of the other classes | |
544 | * | |
545 | * Rate class 0x0002: | |
546 | * - Buddy list add/remove | |
547 | * - Permit list add/remove | |
548 | * - Deny list add/remove | |
549 | * | |
550 | * Rate class 0x0003: | |
551 | * - User information requests | |
552 | * - Outgoing ICBMs | |
553 | * | |
554 | * Rate class 0x0004: | |
555 | * - A few unknowns: 2/9, 2/b, and f/2 | |
556 | * | |
557 | * Rate class 0x0005: | |
558 | * - Chat room create | |
559 | * - Outgoing chat ICBMs | |
560 | * | |
561 | * The only other thing of note is that class 5 (chat) has slightly looser | |
562 | * limiting properties than class 3 (normal messages). But thats just a | |
563 | * small bit of trivia for you. | |
564 | * | |
565 | * The last thing that needs to be learned about the rate limiting | |
566 | * system is how the actual numbers relate to the passing of time. This | |
567 | * seems to be a big mystery. | |

b1eac25a | 799 | * Starting this past week (26 Mar 2001, say), AOL has started sending |
800 | * this nice little extra SNAC. AFAIK, it has never been used until now. | |
801 | * | |
802 | * The request contains eight bytes. The first four are an offset, the | |
803 | * second four are a length. | |
d32954e7 | 804 | * |
b1eac25a | 805 | * The offset is an offset into aim.exe when it is mapped during execution |
806 | * on Win32. So far, AOL has only been requesting bytes in static regions | |
807 | * of memory. (I won't put it past them to start requesting data in | |
808 | * less static regions -- regions that are initialized at run time, but still | |
809 | * before the client recieves this request.) | |
810 | * | |
811 | * When the client recieves the request, it adds it to the current ds | |
812 | * (0x00400000) and dereferences it, copying the data into a buffer which | |
813 | * it then runs directly through the MD5 hasher. The 16 byte output of | |
814 | * the hash is then sent back to the server. | |
815 | * | |
816 | * If the client does not send any data back, or the data does not match | |
817 | * the data that the specific client should have, the client will get the | |
818 | * following message from "AOL Instant Messenger": | |
819 | * "You have been disconnected from the AOL Instant Message Service (SM) | |
820 | * for accessing the AOL network using unauthorized software. You can | |
821 | * download a FREE, fully featured, and authorized client, here | |
822 | * http://www.aol.com/aim/download2.html" | |
823 | * The connection is then closed, recieving disconnect code 1, URL | |
824 | * http://www.aim.aol.com/errors/USER_LOGGED_OFF_NEW_LOGIN.html. | |
825 | * | |
826 | * Note, however, that numerous inconsistencies can cause the above error, | |
827 | * not just sending back a bad hash. Do not immediatly suspect this code | |
828 | * if you get disconnected. AOL and the open/free software community have | |
829 | * played this game for a couple years now, generating the above message | |
830 | * on numerous ocassions. | |
831 | * | |
832 | * Anyway, neener. We win again. | |
