The code consists of three major + * locking domains, each protected with their own disjunct set of locks. + * + * 1: The routing hierarchy. + * Comprises the structures 'zone', 'cluster', 'node', 'link' + * and 'bearer'. The whole hierarchy is protected by a big + * read/write lock, net_lock, to enssure that nothing is added + * or removed while code is accessing any of these structures. + * This layer must not be called from the two others while they + * hold any of their own locks. + * Neither must it itself do any upcalls to the other two before + * it has released net_lock and other protective locks. + * + * Within the net_lock domain there are two sub-domains;'node' and + * 'bearer', where local write operations are permitted, + * provided that those are protected by individual spin_locks + * per instance. Code holding net_lock(read) and a node spin_lock + * is permitted to poke around in both the node itself and its + * subordinate links. I.e, it can update link counters and queues, + * change link state, send protocol messages, and alter the + * "active_links" array in the node; but it can _not_ remove a link + * or a node from the overall structure. + * Correspondingly, individual bearers may change status within a + * net_lock(read), protected by an individual spin_lock ber bearer + * instance, but it needs net_lock(write) to remove/add any bearers. + * + * + * 2: The transport level of the protocol. + * This consists of the structures port, (and its user level + * representations, such as user_port and tipc_sock), reference and + * tipc_user (port.c, reg.c, socket.c). + * + * This layer has four different locks: + * - The tipc_port spin_lock. This is protecting each port instance + * from parallel data access and removal. Since we can not place + * this lock in the port itself, it has been placed in the + * corresponding reference table entry, which has the same life + * cycle as the module. This entry is difficult to access from + * outside the TIPC core, however, so a pointer to the lock has + * been added in the port instance, -to be used for unlocking + * only. + * - A read/write lock to protect the reference table itself (teg.c). + * (Nobody is using read-only access to this, so it can just as + * well be changed to a spin_lock) + * - A spin lock to protect the registry of kernel/driver users (reg.c) + * - A global spin_lock (port_lock), which only task is to ensure + * consistency where more than one port is involved in an operation, + * i.e., whe a port is part of a linked list of ports. + * There are two such lists; 'port_list', which is used for management, + * and 'wait_list', which is used to queue ports during congestion. + * + * 3: The name table (name_table.c, name_distr.c, subscription.c) + * - There is one big read/write-lock (nametbl_lock) protecting the + * overall name table structure. Nothing must be added/removed to + * this structure without holding write access to it. + * - There is one local spin_lock per sub_sequence, which can be seen + * as a sub-domain to the nametbl_lock domain. It is used only + * for translation operations, and is needed because a translation + * steps the root of the 'publication' linked list between each lookup. + * This is always used within the scope of a nametbl_lock(read). + * - A local spin_lock protecting the queue of subscriber events. +*/ + +rwlock_t net_lock = RW_LOCK_UNLOCKED; +struct network net = { 0 }; + +struct node *net_select_remote_node(u32 addr, u32 ref) +{ + return zone_select_remote_node(net.zones[tipc_zone(addr)], addr, ref); +} + +u32 net_select_router(u32 addr, u32 ref) +{ + return zone_select_router(net.zones[tipc_zone(addr)], addr, ref); +} + + +u32 net_next_node(u32 a) +{ + if (net.zones[tipc_zone(a)]) + return zone_next_node(a); + return 0; +} + +void net_remove_as_router(u32 router) +{ + u32 z_num; + + for (z_num = 1; z_num <= tipc_max_zones; z_num++) { + if (!net.zones[z_num]) + continue; + zone_remove_as_router(net.zones[z_num], router); + } +} + +void net_send_external_routes(u32 dest) +{ + u32 z_num; + + for (z_num = 1; z_num <= tipc_max_zones; z_num++) { + if (net.zones[z_num]) + zone_send_external_routes(net.zones[z_num], dest); + } +} + +int net_init(void) +{ + u32 sz = sizeof(struct _zone *) * (tipc_max_zones + 1); + + memset(&net, 0, sizeof(net)); + net.zones = (struct _zone **)kmalloc(sz, GFP_ATOMIC); + if (!net.zones) { + return -ENOMEM; + } + memset(net.zones, 0, sz); + return TIPC_OK; +} + +void net_stop(void) +{ + u32 z_num; + + if (!net.zones) + return; + + for (z_num = 1; z_num <= tipc_max_zones; z_num++) { + zone_delete(net.zones[z_num]); + } + kfree(net.zones); + net.zones = 0; +} + +static void net_route_named_msg(struct sk_buff *buf) +{ + struct tipc_msg *msg = buf_msg(buf); + u32 dnode; + u32 dport; + + if (!msg_named(msg)) { + msg_dbg(msg, "net->drop_nam:"); + buf_discard(buf); + return; + } + + dnode = addr_domain(msg_lookup_scope(msg)); + dport = nametbl_translate(msg_nametype(msg), msg_nameinst(msg), &dnode); + dbg("net->lookup<%u,%u>-><%u,%x>\n", + msg_nametype(msg), msg_nameinst(msg), dport, dnode); + if (dport) { + msg_set_destnode(msg, dnode); + msg_set_destport(msg, dport); + net_route_msg(buf); + return; + } + msg_dbg(msg, "net->rej:NO NAME: "); + tipc_reject_msg(buf, TIPC_ERR_NO_NAME); +} + +void net_route_msg(struct sk_buff *buf) +{ + struct tipc_msg *msg; + u32 dnode; + + if (!buf) + return; + msg = buf_msg(buf); + + msg_incr_reroute_cnt(msg); + if (msg_reroute_cnt(msg) > 6) { + if (msg_errcode(msg)) { + msg_dbg(msg, "NET>DISC>:"); + buf_discard(buf); + } else { + msg_dbg(msg, "NET>REJ>:"); + tipc_reject_msg(buf, msg_destport(msg) ? + TIPC_ERR_NO_PORT : TIPC_ERR_NO_NAME); + } + return; + } + + msg_dbg(msg, "net->rout: "); + + /* Handle message for this node */ + dnode = msg_short(msg) ? tipc_own_addr : msg_destnode(msg); + if (in_scope(dnode, tipc_own_addr)) { + if (msg_isdata(msg)) { + if (msg_mcast(msg)) + port_recv_mcast(buf, NULL); + else if (msg_destport(msg)) + port_recv_msg(buf); + else + net_route_named_msg(buf); + return; + } + switch (msg_user(msg)) { + case ROUTE_DISTRIBUTOR: + cluster_recv_routing_table(buf); + break; + case NAME_DISTRIBUTOR: + named_recv(buf); + break; + case CONN_MANAGER: + port_recv_proto_msg(buf); + break; + default: + msg_dbg(msg,"DROP/NET/<REC<"); + buf_discard(buf); + } + return; + } + + /* Handle message for another node */ + msg_dbg(msg, "NET>SEND>: "); + link_send(buf, dnode, msg_link_selector(msg)); +} + +int tipc_start_net(void) +{ + char addr_string[16]; + int res; + + if (tipc_mode != TIPC_NODE_MODE) + return -ENOPROTOOPT; + + tipc_mode = TIPC_NET_MODE; + named_reinit(); + port_reinit(); + + if ((res = bearer_init()) || + (res = net_init()) || + (res = cluster_init()) || + (res = bclink_init())) { + return res; + } + subscr_stop(); + cfg_stop(); + k_signal((Handler)subscr_start, 0); + k_signal((Handler)cfg_init, 0); + info("Started in network mode\n"); + info("Own node address %s, network identity %u\n", + addr_string_fill(addr_string, tipc_own_addr), tipc_net_id); + return TIPC_OK; +} + +void tipc_stop_net(void) +{ + if (tipc_mode != TIPC_NET_MODE) + return; + write_lock_bh(&net_lock); + bearer_stop(); + tipc_mode = TIPC_NODE_MODE; + bclink_stop(); + net_stop(); + write_unlock_bh(&net_lock); + info("Left network mode \n"); +} + diff --git a/net/tipc/net.h b/net/tipc/net.h new file mode 100644 index 000000000000..948c6d42102c --- /dev/null +++ b/net/tipc/net.h @@ -0,0 +1,66 @@ +/* + * net/tipc/net.h: Include file for TIPC network routing code + * + * Copyright (c) 1995-2006, Ericsson AB + * Copyright (c) 2005, Wind River Systems + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * + * 1.
