2015-01-12tipc: make tipc node address support net namespaceYing Xue17-194/+246
If net namespace is supported in tipc, each namespace will be treated as a separate tipc node. Therefore, every namespace must own its private tipc node address. This means the "tipc_own_addr" global variable of node address must be moved to tipc_net structure to satisfy the requirement. It's turned out that users also can assign node address for every namespace.

2015-01-12tipc: name tipc name table support net namespaceYing Xue15-116/+154
TIPC name table is used to store the mapping relationship between TIPC service name and socket port ID. When tipc supports namespace, it allows users to publish service names only owned by a certain namespace. Therefore, every namespace must have its private name table to prevent service names published to one namespace from being contaminated by other service names in another namespace. Therefore, The name table global variable (ie, nametbl) and its lock must be moved to tipc_net structure, and a parameter of namespace must be added for necessary functions so that they can obtain name table variable defined in tipc_net structure.

2015-01-12tipc: make tipc socket support net namespaceYing Xue6-33/+43
Now tipc socket table is statically allocated as a global variable. Through it, we can look up one socket instance with port ID, insert a new socket instance to the table, and delete a socket from the table. But when tipc supports net namespace, each namespace must own its specific socket table. So the global variable of socket table must be redefined in tipc_net structure. As a concequence, a new socket table will be allocated when a new namespace is created, and a socket table will be deallocated when namespace is destroyed.

TIPC broadcast link is statically established and its relevant states are maintained with the global variables: "bcbearer", "bclink" and "bcl".

2015-01-12tipc: make bearer list support net namespaceYing Xue10-73/+110
Bearer list defined as a global variable is used to store bearer instances. When tipc supports net namespace, bearers created in one namespace must be isolated with others allocated in other namespaces, which requires us that the bearer list(bearer_list) must be moved to tipc_net structure. As a result, a net namespace pointer has to be passed to functions which access the bearer list.

2015-01-12tipc: make tipc node table aware of net namespaceYing Xue21-244/+329
Global variables associated with node table are below: - node table list (node_htable) - node hash table list (tipc_node_list) - node table lock (node_list_lock) - node number counter (tipc_num_nodes) - node link number counter (tipc_num_links) To make node table support namespace, above global variables must be moved to tipc_net structure in order to keep secret for different namespaces. As a consequence, these variables are allocated and initialized when namespace is created, and deallocated when namespace is destroyed. After the change, functions associated with these variables have to utilize a namespace pointer to access them. So adding namespace pointer as a parameter of these functions is the major change made in the commit.

2015-01-12tipc: feed tipc sock pointer to tipc_sk_timeout routineYing Xue1-17/+16
In order to make tipc socket table aware of namespace, a networking namespace instance must be passed to tipc_sk_lookup(), allowing it to look up tipc socket instance with a given port ID from a concrete socket table. However, as now tipc_sk_timeout() only has one port ID parameter and is not namespace aware, it's unable to obtain a correct socket instance through tipc_sk_lookup() just with a port ID, especially after namespace is completely supported. If port ID is replaced with socket instance as tipc_sk_timeout()'s parameter, it's unnecessary to look up socket table. But as the timer handler - tipc_sk_timeout() is run asynchronously, socket reference must be held before its timer is launched, and must be carefully checked to identify whether the socket reference needs to be put or not when its timer is terminated.

2015-01-12tipc: fix bug in broadcast retransmit codeJon Maloy1-2/+3
In commit 58dc55f25631178ee74cd27185956a8f7dcb3e32 ("tipc: use generic SKB list APIs to manage link transmission queue") we replace all list traversal loops with the macros skb_queue_walk() or skb_queue_walk_safe(). While the previous loops were based on the assumption that the list was NULL-terminated, the standard macros stop when the iterator reaches the list head, which is non-NULL. In the function bclink_retransmit_pkt() this macro replacement has lead to a bug. When we receive a BCAST STATE_MSG we unconditionally call the function bclink_retransmit_pkt(), whether there really is anything to retransmit or not, assuming that the sequence number comparisons will lead to the correct behavior. However, if the transmission queue is empty, or if there are no eligible buffers in the transmission queue, we will by mistake pass the list head pointer to the function tipc_link_retransmit(). Since the list head is not a valid sk_buff, this leads to a crash. In this commit we fix this by only calling tipc_link_retransmit() if we actually found eligible buffers in the transmission queue.

As tipc reference table is statically allocated, its memory size requested on stack initialization stage is quite big even if the maximum port number is just restricted to 8191 currently, however, the number already becomes insufficient in practice. But if the maximum ports is allowed to its theory value - 2^32, its consumed memory size will reach a ridiculously unacceptable value. Apart from this, heavy tipc users spend a considerable amount of time in tipc_sk_get() due to the read-lock on ref_table_lock. If tipc reference table is converted with generic rhashtable, above mentioned both disadvantages would be resolved respectively: making use of the new resizable hash table can avoid locking on the lookup; smaller memory size is required at initial stage, for example, 256 hash bucket slots are requested at the beginning phase instead of allocating the entire 8191 slots in old mode. The hash table will grow if entries exceeds 75% of table size up to a total table size of 1M, and it will automatically shrink if usage falls below 30%, but the minimum table size is allowed down to 256. Also converts ref_table_lock to a separate mutex to protect hash table mutations on write side. Lastly defers the release of the socket reference using call_rcu() to allow using an RCU read-side protected call to rhashtable_lookup().

2015-01-08rhashtable: future table needs to be traversed when remove an objectYing Xue1-2/+2
When remove an object from hash table, we currently only traverse old bucket table to check whether the object exists. If the object is not found in it, we will try again. But in the second search loop, we still search the object from the old table instead of future table. As a result, the object may be not removed from hash table especially when resizing is currently in progress and the object is just saved in the future table.

2015-01-08rhashtable: involve rhashtable_lookup_insert routineYing Xue2-15/+83
Involve a new function called rhashtable_lookup_insert() which makes lookup and insertion atomic under bucket lock protection, helping us avoid to introduce an extra lock when we search and insert an object into hash table.

2015-01-08rhashtable: introduce rhashtable_wakeup_worker helper functionYing Xue1-8/+15
Introduce rhashtable_wakeup_worker() helper function to reduce duplicated code where to wake up worker. By the way, as long as the both "future_tbl" and "tbl" bucket table pointers point to the same bucket array, we should try to wake up the resizing worker thread, otherwise, it indicates the work of resizing hash table is not finished yet. However, currently we will wake up the worker thread only when the two pointers point to different bucket array. Obviously this is wrong. So, the issue is also fixed as well in the patch.
