/* * conn.c * * Does all this gloriously nifty connection handling stuff... * */ #include #include "sock.h" static int aim_logoff(aim_session_t *sess); /* * In OSCAR, every connection has a set of SNAC groups associated * with it. These are the groups that you can send over this connection * without being guarenteed a "Not supported" SNAC error. * * The grand theory of things says that these associations transcend * what libfaim calls "connection types" (conn->type). You can probably * see the elegance here, but since I want to revel in it for a bit, you * get to hear it all spelled out. * * So let us say that you have your core BOS connection running. One * of your modules has just given you a SNAC of the group 0x0004 to send * you. Maybe an IM destined for some twit in Greenland. So you start * at the top of your connection list, looking for a connection that * claims to support group 0x0004. You find one. Why, that neat BOS * connection of yours can do that. So you send it on its way. * * Now, say, that fellow from Greenland has friends and they all want to * meet up with you in a lame chat room. This has landed you a SNAC * in the family 0x000e and you have to admit you're a bit lost. You've * searched your connection list for someone who wants to make your life * easy and deliver this SNAC for you, but there isn't one there. * * Here comes the good bit. Without even letting anyone know, particularly * the module that decided to send this SNAC, and definitly not that twit * in Greenland, you send out a service request. In this request, you have * marked the need for a connection supporting group 0x000e. A few seconds * later, you receive a service redirect with an IP address and a cookie in * it. Great, you say. Now I have something to do. Off you go, making * that connection. One of the first things you get from this new server * is a message saying that indeed it does support the group you were looking * for. So you continue and send rate confirmation and all that. * * Then you remember you had that SNAC to send, and now you have a means to * do it, and you do, and everyone is happy. Except the Greenlander, who is * still stuck in the bitter cold. * * Oh, and this is useful for building the Migration SNACs, too. In the * future, this may help convince me to implement rate limit mitigation * for real. We'll see. * * Just to make me look better, I'll say that I've known about this great * scheme for quite some time now. But I still haven't convinced myself * to make libfaim work that way. It would take a fair amount of effort, * and probably some client API changes as well. (Whenever I don't want * to do something, I just say it would change the client API. Then I * instantly have a couple of supporters of not doing it.) * * Generally, addgroup is only called by the internal handling of the * server ready SNAC. So if you want to do something before that, you'll * have to be more creative. That is done rather early, though, so I don't * think you have to worry about it. Unless you're me. I care deeply * about such inane things. * */ void aim_conn_addgroup(aim_conn_t *conn, guint16 group) { aim_conn_inside_t *ins = (aim_conn_inside_t *)conn->inside; struct snacgroup *sg; if (!(sg = g_malloc(sizeof(struct snacgroup)))) return; sg->group = group; sg->next = ins->groups; ins->groups = sg; return; } aim_conn_t *aim_conn_findbygroup(aim_session_t *sess, guint16 group) { aim_conn_t *cur; for (cur = sess->connlist; cur; cur = cur->next) { aim_conn_inside_t *ins = (aim_conn_inside_t *)cur->inside; struct snacgroup *sg; for (sg = ins->groups; sg; sg = sg->next) { if (sg->group == group) return cur; } } return NULL; } static void connkill_snacgroups(struct snacgroup **head) { struct snacgroup *sg; for (sg = *head; sg; ) { struct snacgroup *tmp; tmp = sg->next; g_free(sg); sg = tmp; } *head = NULL; return; } static void connkill_rates(struct rateclass **head) { struct rateclass *rc; for (rc = *head; rc; ) { struct rateclass *tmp; struct snacpair *sp; tmp = rc->next; for (sp = rc->members; sp; ) { struct snacpair *tmpsp; tmpsp = sp->next; g_free(sp); sp = tmpsp; } g_free(rc); rc = tmp; } *head = NULL; return; } static void connkill_real(aim_session_t *sess, aim_conn_t **deadconn) { aim_rxqueue_cleanbyconn(sess, *deadconn); aim_tx_cleanqueue(sess, *deadconn); if ((*deadconn)->fd != -1) aim_conn_close(*deadconn); /* * XXX ->priv should never be touched by the library.
