git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux Paul Gortmaker says: ==================== The most interesting thing here, at least from a user perspective, is the broadcast link fix -- where there was a corner case where two endpoints could get in a state where they disagree on where to start Rx and ack of broadcast packets. There is also the poll/wait changes which could also impact end users for certain use cases - the fixes there also better align tipc with the rest of the networking code.

2012-11-22tipc: delete TIPC_ADVANCED Kconfig variablePaul Gortmaker
There used to be a time when TIPC had lots of Kconfig knobs the end user could alter, but they have all been made automatic or obsolete, with the exception of CONFIG_TIPC_PORTS. This previously existing set of options was all hidden under the TIPC_ADVANCED setting, which does not exist in any code, but only in Kconfig scope. Having this now, just to hide the one remaining "advanced" option no longer makes sense. Remove it. Also get rid of the ifdeffery in the TIPC code that allowed for TIPC_PORTS to be possibly undefined. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2012-11-22tipc: introduce message to synchronize broadcast linkJon Maloy
Upon establishing a first link between two nodes, there is currently a risk that the two endpoints will disagree on exactly which sequence number reception and acknowleding of broadcast packets should start. The following scenarios may happen: 1: Node A sends an ACTIVATE message to B, telling it to start acking packets from sequence number N. 2: Node A sends out broadcast N, but does not expect an acknowledge from B, since B is not yet in its broadcast receiver's list. 3: Node A receives ACK for N from all nodes except B, and releases packet N. 4: Node B receives the ACTIVATE, activates its link endpoint, and stores the value N as sequence number of first expected packet. 5: Node B sends a NAME_DISTR message to A. 6: Node A receives the NAME_DISTR message, and activates its endpoint. At this moment B is added to A's broadcast receiver's set. Node A also sets sequence number 0 as the first broadcast packet to be received from B. 7: Node A sends broadcast N+1. 8: B receives N+1, determines there is a gap in the sequence, since it is expecting N, and sends a NACK for N back to A. 9: Node A has already released N, so no retransmission is possible. The broadcast link in direction A->B is stale. In addition to, or instead of, 7-9 above, the following may happen: 10: Node B sends broadcast M > 0 to A. 11: Node A receives M, falsely decides there must be a gap, since it is expecting packet 0, and asks for retransmission of packets [0,M-1]. 12: Node B has already released these packets, so the broadcast link is stale in direction B->A. We solve this problem by introducing a new unicast message type, BCAST_PROTOCOL/STATE, to convey the sequence number of the next sent broadcast packet to the other endpoint, at exactly the moment that endpoint is added to the own node's broadcast receivers list, and before any other unicast messages are permitted to be sent. Furthermore, we don't allow any node to start receiving and processing broadcast packets until this new synchronization message has been received. To maintain backwards compatibility, we still open up for broadcast reception if we receive a NAME_DISTR message without any preceding broadcast sync message. In this case, we must assume that the other end has an older code version, and will never send out the new synchronization message. Hence, for mixed old and new nodes, the issue arising in 7-12 of the above may happen with the same probability as before.

2012-11-22tipc: remove supportable flag from bclink structureYing Xue
The "supportable" flag in bclink structure is a compatibility flag indicating whether a peer node is capable of receiving TIPC broadcast messages. However, all TIPC versions since tipc-1.5, and after the inclusion in the upstream Linux kernel in 2006, support this capability. It is highly unlikely that anybody is still using such an old version of TIPC, let alone that they want to mix it with TIPC-2.0 nodes. Therefore, we now remove the "supportable" flag.

There was a bitwise operation error in the fdb_add block that was only allowing FDB types that were not permanent. This was the opposite of the intent because the hardware never ages out address these are the _only_ type of addrs that should be allowed. This was missed because until recently iproute2 did not set any bit for this by default. And our test code to manage FDB entries on embedded devices similarly did not set these bits.

2012-11-22tipc: remove the bearer congestion mechanismYing Xue
Currently at the TIPC bearer layer there is the following congestion mechanism: Once sending packets has failed via that bearer, the bearer will be flagged as being in congested state at once. During bearer congestion, all packets arriving at link will be queued on the link's outgoing buffer. When we detect that the state of bearer congestion has relaxed (e.g. some packets are received from the bearer) we will try our best to push all packets in the link's outgoing buffer until the buffer is empty, or until the bearer is congested again. However, in fact the TIPC bearer never receives any feedback from the device layer whether a send was successful or not, so it must always assume it was successful. Therefore, the bearer congestion mechanism as it exists currently is of no value. But the bearer blocking state is still useful for us. For example, when the physical media goes down/up, we need to change the state of the links bound to the bearer. So the code maintaing the state information is not removed.

2012-11-22tipc: wake up all waiting threads at socket shutdownYing Xue
When a socket is shut down, we should wake up all thread sleeping on it, instead of just one of them. Otherwise, when several threads are polling the same socket, and one of them does shutdown(), the remaining threads may end up sleeping forever. Also, to align socket usage with common practice in other stacks, we use one of the common socket callback handlers, sk_state_change(), to wake up pending users. This is similar to the usage in e.g. inet_shutdown(). [net/ipv4/af_inet.c].

2012-11-21tipc: return POLLOUT for sockets in an unconnected stateErik Hugne
If an implied connect is attempted on a nonblocking STREAM/SEQPACKET socket during link congestion, the connect message will be discarded and sendmsg will return EAGAIN. This is normal behavior, and the application is expected to poll the socket until POLLOUT is set, after which the connection attempt can be retried. However, the POLLOUT flag is never set for unconnected sockets and poll() always returns a zero mask. The application is then left without a trigger for when it can make another attempt at sending the message. The solution is to check if we're polling on an unconnected socket and set the POLLOUT flag if the TIPC port owned by this socket is not congested. The TIPC ports waiting on a specific link will be marked as 'not congested' when the link congestion have abated.

2012-11-21tipc: fix race/inefficiencies in poll/wait behaviourYing Xue
When an application blocks at poll/select on a TIPC socket while requesting a specific event mask, both the filter_rcv() and wakeupdispatch() case will wake it up unconditionally whenever the state changes (i.e an incoming message arrives, or congestion has subsided). No mask is used. To avoid this, we populate sk->sk_data_ready and sk->sk_write_space with tipc_data_ready and tipc_write_space respectively, which makes tipc more in alignment with the rest of the networking code. These pass the exact set of possible events to the waker in fs/select.c hence avoiding waking up blocked processes unnecessarily. In doing so, we uncover another issue -- that there needs to be a memory barrier in these poll/receive callbacks, otherwise we are subject to the the same race as documented above wq_has_sleeper() [in commit a57de0b4 "net: adding memory barrier to the poll and receive callbacks"]. So we need to replace poll_wait() with sock_poll_wait() and use rcu protection for the sk->sk_wq pointer in these two new functions.

2012-11-21batman-adv: Use packing of 2 for all headers before an ethernet headerSven Eckelmann
All packet headers in front of an ethernet header have to be completely divisible by 2 but not by 4 to make the payload after the ethernet header again 4 bytes boundary aligned. A packing of 2 is necessary to avoid extra padding at the end of the struct caused by a structure member which is larger than two bytes. Otherwise the structure would not fulfill the previously mentioned rule to avoid the misalignment of the payload after the ethernet header. It may also lead to leakage of information when the padding it not initialized before sending.
