As a consequence of the recently introduced serialized access to the socket in commit 8d94168a761819d10252bab1f8de6d7b202c3baa ("tipc: same receive code path for connection protocol and data messages") we can make a number of simplifications in the detection and handling of connection congestion situations. - We don't need to keep two counters, one for sent messages and one for acked messages. There is no longer any risk for races between acknowledge messages arriving in BH and data message sending running in user context. So we merge this into one counter, 'sent_unacked', which is incremented at sending and subtracted from at acknowledge reception. - We don't need to set the 'congested' field in tipc_port to true before we sent the message, and clear it when sending is successful. (As a matter of fact, it was never necessary; the field was set in link_schedule_port() before any wakeup could arrive anyway.) - We keep the conditions for link congestion and connection connection congestion separated. There would otherwise be a risk that an arriving acknowledge message may wake up a user sleeping because of link congestion. - We can simplify reception of acknowledge messages. We also make some cosmetic/structural changes: - We rename the 'congested' field to the more correct 'link_cong´. - We rename 'conn_unacked' to 'rcv_unacked' - We move the above mentioned fields from struct tipc_port to struct tipc_sock.

We simplify the code for receiving connection probes, leveraging the recently introduced tipc_msg_reverse() function. We also stick to the principle of sending a possible response message directly from the calling (tipc_sk_rcv or backlog_rcv) functions, hence making the call chain shallower and easier to follow. We make one small protocol change here, allowed according to the spec. If a protocol message arrives from a remote socket that is not the one we are connected to, we are currently generating a connection abort message and send it to the source. This behavior is unnecessary, and might even be a security risk, so instead we now choose to only ignore the message. The consequnce for the sender is that he will need longer time to discover his mistake (until the next timeout), but this is an extreme corner case, and may happen anyway under other circumstances, so we deem this change acceptable.

As a preparation to eliminate port_lock we need to bring reception of connection protocol messages under proper protection of bh_lock_sock or socket owner. We fix this by letting those messages follow the same code path as incoming data messages. As a side effect of this change, the last reference to the function net_route_msg() disappears, and we can eliminate that function.

We move the message sending across established connections to use the message preparation and send functions introduced earlier in this series. We now do the message preparation and call to the link send function directly from the socket, instead of going via the port layer. As a consequence of this change, the functions tipc_send(), tipc_port_iovec_rcv(), tipc_port_iovec_reject() and tipc_reject_msg() become unreferenced and can be eliminated from port.c. For the same reason, the functions tipc_link_xmit_fast(), tipc_link_iovec_xmit_long() and tipc_link_iovec_fast() can be eliminated from link.c.

We merge the code for sending port name and port identity addressed messages into the corresponding send functions in socket.c, and start using the new fragmenting and transmit functions we just have introduced. This saves a call level and quite a few code lines, as well as making this part of the code easier to follow. As a consequence, the functions tipc_send2name() and tipc_send2port() in port.c can be removed. For practical reasons, we break out the code for sending multicast messages from tipc_sendmsg() and move it into a separate function, tipc_sendmcast(), but we do not yet convert it into using the new build/send functions.

As an artefact from the native interface, the message sending functions in the port takes a port ref as first parameter, and then looks up in the registry to find the corresponding port pointer. This despite the fact that the only currently existing caller, tipc_sock, already knows this pointer. We change the signature of these functions to take a struct tipc_port* argument, and remove the redundant lookups. We also remove an unmotivated extra lookup in the function socket.c:auto_connect(), and, as the lookup functions tipc_port_deref() and ref_deref() now become unused, we remove these two functions.

Due to the original one-to-many relation between port and user API layers, upcalls to the API have been performed via function pointers, installed in struct tipc_port at creation. Since this relation now always is one-to-one, we can instead use ordinary function calls. We remove the function pointers 'dispatcher' and ´wakeup' from struct tipc_port, and replace them with calls to the renamed functions tipc_sk_rcv() and tipc_sk_wakeup(). At the same time we change the name and signature of the functions tipc_createport() and tipc_deleteport() to reflect their new role as mere initialization/destruction functions.

After the removal of the tipc native API the relation between a tipc_port and its API types is strictly one-to-one, i.e, the latter can now only be a socket API. There is therefore no need to allocate struct tipc_port and struct sock independently. In this commit, we aggregate struct tipc_port into struct tipc_sock, hence saving both CPU cycles and structure complexity. There are no functional changes in this commit, except for the elimination of the separate allocation/freeing of tipc_port. All other changes are just adaptatons to the new data structure. This commit also opens up for further code simplifications and code volume reduction, something we will do in later commits.

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>

The tipc_printf is renamed to tipc_snprintf, as the new name describes more what the function actually does. It is also changed to take a buffer and length parameter and return number of characters written to the buffer. All callers of this function that used to pass a print_buf are updated. Final removal of the struct print_buf itself will be done synchronously with the pending removal of the deprecated logging code that also was using it. Functions that build up a response message with a list of ports, nametable contents etc. are changed to return the number of characters written to the output buffer. This information was previously hidden in a field of the print_buf struct, and the number of chars written was fetched with a call to tipc_printbuf_validate. This function is removed since it is no longer referenced nor needed. A generic max size ULTRA_STRING_MAX_LEN is defined, named in keeping with the existing TIPC_TLV_ULTRA_STRING, and the various definitions in port, link and nametable code that largely duplicated this information are removed. This means that amount of link statistics that can be returned is now increased from 2k to 32k. The buffer overflow check is now done just before the reply message is passed over netlink or TIPC to a remote node and the message indicating a truncated buffer is changed to a less dramatic one (less CAPS), placed at the end of the message.

Revises routines that deal with connections between two ports on the same node to ensure the connection is not impacted if the node's network address is changed in mid-operation. The routines now treat the default node address of <0.0.0> as an alias for "this node" in the following situations: 1) Incoming messages destined to a connected port now handle the alias properly when validating that the message was sent by the expected peer port, ensuring that the message will be accepted regardless of whether it specifies the node's old network address or it's current one. 2) The code which completes connection establishment now handles the alias properly when determining if the peer port is on the same node as the connected port. An added benefit of addressing issue 1) is that some peer port validation code has been relocated to TIPC's socket subsystem, which means that validation is no longer done twice when a message is sent to a non-socket port (such as TIPC's configuration service or network topology service).

Optimizes routines that send payload messages so that they no longer update the "originating node" and "originating port" fields of the outgoing message header template, since these fields are initialized when the sending port is created and never change thereafter. Also optimizes the routine which updates the message header template when a connection to a port is established, for the same reason.

Converts a non-trivial routine from inline to non-inline form to avoid bloating the TIPC code base with 6 copies of its body. This change is essentially cosmetic, and doesn't change existing TIPC behavior.

Restores name table translation using a non-zero domain that is "out of scope", which was broken by an earlier commit (5d9c54c1). Comments have now been added to the name table translation routine to make it clear that there are actually three possible outcomes to a translation request (found/not found/deferred), rather than just two (found/not found). Note that a straightforward revert of the earlier commit is not possible, as other changes to the name table translation logic have occurred since the incorrect optimization was made.
