TIPC establishes one subscriber server which allows users to subscribe their interesting name service status. After tipc supports namespace, one dedicated tipc stack instance is created for each namespace, and each instance can be deemed as one independent TIPC node. As a result, subscriber server must be built for each namespace.

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.

When a topology server subscriber is disconnected, the associated connection id is set to zero. A check vs zero is then done in the subscription timeout function to see if the subscriber have been shut down. This is unnecessary, because all subscription timers will be cancelled when a subscriber terminates. Setting the connection id to zero is actually harmful because id zero is the identity of the topology server listening socket, and can cause a race that leads to this socket being closed instead.

Currently connection shutdown callback function is called when connection instance is released in tipc_conn_kref_release(), and receiving packets and sending packets are running in different threads. Even if connection is closed by the thread of receiving packets, its shutdown callback may not be called immediately as the connection reference count is non-zero at that moment. So, although the connection is shut down by the thread of receiving packets, the thread of sending packets doesn't know it. Before its shutdown callback is invoked to tell the sending thread its connection has been closed, the sending thread may deliver messages by tipc_conn_sendmsg(), this is why the following error information appears: "Sending subscription event failed, no memory" To eliminate it, allow connection shutdown callback function to be called before connection id is removed in tipc_close_conn(), which makes the sending thread know the truth in time that its socket is closed so that it doesn't send message to it. We also remove the "Sending XXX failed..." error reporting for topology and config services.

As the new TIPC server infrastructure has been introduced, we can now convert the TIPC topology server to it. We get two benefits from doing this: 1) It simplifies the topology server locking policy. In the original locking policy, we placed one spin lock pointer in the tipc_subscriber structure to reuse the lock of the subscriber's server port, controlling access to members of tipc_subscriber instance. That is, we only used one lock to ensure both tipc_port and tipc_subscriber members were safely accessed. Now we introduce another spin lock for tipc_subscriber structure only protecting themselves, to get a finer granularity locking policy. Moreover, the change will allow us to make the topology server code more readable and maintainable. 2) It fixes a bug where sent subscription events may be lost when the topology port is congested. Using the new service, the topology server now queues sent events into an outgoing buffer, and then wakes up a sender process which has been blocked in workqueue context. The process will keep picking events from the buffer and send them to their respective subscribers, using the kernel socket interface, until the buffer is empty. Even if the socket is congested during transmission there is no risk that events may be dropped, since the sender process may block when needed. Some minor reordering of initialization is done, since we now have a scenario where the topology server must be started after socket initialization has taken place, as the former depends on the latter. And overall, we see a simplification of the TIPC subscriber code in making this changeover.

Currently we have tipc_disconnect and tipc_disconnect_port. It is not clear from the names alone, what they do or how they differ. It turns out that tipc_disconnect just deals with the port locking and then calls tipc_disconnect_port which does all the work. If we rename as follows: tipc_disconnect_port --> __tipc_disconnect then we will be following typical linux convention, where: __tipc_disconnect: "raw" function that does all the work. tipc_disconnect: wrapper that deals with locking and then calls the real core __tipc_disconnect function With this, the difference is immediately evident, and locking violations are more apt to be spotted by chance while working on, or even just while reading the code. On the connect side of things, we currently only have the single "tipc_connect2port" function. It does both the locking at enter/exit, and the core of the work. Pending changes will make it desireable to have the connect be a two part locking wrapper + worker function, just like the disconnect is already. Here, we make the connect look just like the updated disconnect case, for the above reason, and for consistency. In the process, we also get rid of the "2port" suffix that was on the original name, since it adds no descriptive value. On close examination, one might notice that the above connect changes implicitly move the call to tipc_link_get_max_pkt() to be within the scope of tipc_port_lock() protected region; when it was not previously. We don't see any issues with this, and it is in keeping with __tipc_connect doing the work and tipc_connect just handling the locking. Signed-off-by: NPaul Gortmaker <paul.gortmaker@windriver.com>

Rework TIPC's message sending routines to take advantage of the total amount of data value passed to it by the kernel socket infrastructure. This change eliminates the need for TIPC to compute the size of outgoing messages itself, as well as the check for an oversize message in tipc_msg_build(). In addition, this change warrants an explanation: - res = send_packet(NULL, sock, &my_msg, 0); + res = send_packet(NULL, sock, &my_msg, bytes_to_send); Previously, the final argument to send_packet() was ignored (since the amount of data being sent was recalculated by a lower-level routine) and we could just pass in a dummy value (0). Now that the recalculation is being eliminated, the argument value being passed to send_packet() is significant and we have to supply the actual amount of data we want to send.

Remove htohl implementation from tipc I was working on forward porting the downstream commits for TIPC and ran accross this one: http://tipc.cslab.ericsson.net/cgi-bin/gitweb.cgi?p=people/allan/tipc.git;a=commitdiff;h=894279b9437b63cbb02405ad5b8e033b51e4e31e I was going to just take it, when I looked closer and noted what it was doing. This is basically a routine to byte swap fields of data in sent/received packets for tipc, dependent upon the receivers guessed endianness of the peer when a connection is established. Asside from just seeming silly to me, it appears to violate the latest RFC draft for tipc: http://tipc.sourceforge.net/doc/draft-spec-tipc-02.txt Which, according to section 4.2 and 4.3.3, requires that all fields of all commands be sent in network byte order. So instead of just taking this patch, instead I'm removing the htohl function and replacing the calls with calls to ntohl in the rx path and htonl in the send path. As part of this fix, I'm also changing the subscr_cancel function, which searches the list of subscribers, using a memcmp of the entire subscriber list, for the entry to tear down. unfortunately it memcmps the entire tipc_subscr structure which has several bits that are private to the local side, so nothing will ever match. section 5.2 of the draft spec indicates the <type,upper,lower> tuple should uniquely identify a subscriber, so convert subscr_cancel to just match on those fields (properly endian swapped). I've tested this using the tipc test suite, and its passed without issue. Signed-off-by: NNeil Horman <nhorman@tuxdriver.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
