2013-06-18Revert "mac80211: in IBSS use the Auth frame to trigger STA reinsertion"Antonio Quartulli
This reverts commit 6d810f10325522cfcf498dc6d64b9f96e1f5153f In this way an IBSS station will not use the AUTH messages to trigger a state reinitialisation anymore. The behaviour was racy and was not working properly. It has been introduced to help wpa_supplicant to support IBSS/RSN, however all the logic is now getting moved into wpa_s itself which will also be in charge of handling the AUTH messages thanks to the mgmt frame registration. If userspace does not register for receiving AUTH frames then mac80211 will still reply by itself. At the same time, the auth frame registration counter can be removed since it is not needed anymore.

2013-06-18mac80211: update mesh beacon on workqueueThomas Pedersen
Instead of updating the mesh beacon immediately when requested (which would require the sdata_lock()), defer it to the mac80211 workqueue. Fixes yet another deadlock on calling sta_info_flush() with the sdata_lock() held from ieee80211_stop_mesh(). We could just drop the sdata_lock() around the mesh_sta_cleanup() call, but this path is also taken from several non-locked error paths.

2013-06-17vlan: restore ethtool ABI to control VLAN hardware accelerationFernando Luis Vazquez Cao
As part of the push to add 802.1ad server provider tagging support to the kernel the VLAN features flags were renamed. Unfortunately the kernel name for the VLAN hardware acceleration features that the kernel shows user space was included in the rename, which broke ethtool (txvlan and rxvlan options do not work). This patch restores the original names, i.e. the original ABI. If we wanted to make clear to users that we are refering to CTAGs we can always change ethtool's short_name and long_name for these features (for example something along the lines of txvlan -> txvlan-ctag, tx-vlan-offload -> tx-vlan-ctag-offload).

Many of these are one- or two-liners, and a couple of others are mostly relocating existing code to avoid races or to limit the code to effecting specific hardware, etc. The mac80211 fixes have a couple of exceptions to the above. Regarding those, Johannes says: "Following davem's complaint about my patch, here's a new pull request w/o the patch he was complaining about, but instead with the const fix rolled into the fix. I have a fix for radar detection, one for rate control and a workaround for broken HT APs which is a regression fix because we didn't rely on them to be correct before." Johannes also sends some iwlwifi fixes: "I picked up Nikolay's patch for the chain noise calibration bug that seems to have been there forever, a fix from Emmanuel for setting TX flags on BAR frames and a fix of my own to avoid printing request_module() errors if the kernel isn't even modular. We also have our own version of Stanislaw's fix for rate control." Along with those... Anderson Lizardo fixes a Bluetooth memory corruption bug when an MTU value is set to too small of a value. Arend van Spriel sends a revised brcmsmac bug that fixes a regression caused by a bad return value in an earlier patch. He also sends a brcmfmac fix to avoid an oops when loading the driver at boot.

2013-06-17tipc: enhance priority of link protocol packetYing Xue
pfifo_fast is set as default traffic class queueing discipline. This queue has three so called "bands". Within each band, FIFO rules apply. However, as long as there are packets waiting in band 0, band 1 won't be processed. Now all kind of TIPC type packet priorities are never set, that is, their priorities are 0, so they are mapped to band 1 of pfifo_fast qdisc. But, especially during link congestion, if link protocol packet can be sent out as earlier as possible than other type of packets so that protocol packet can arrive at peer endpoint in time, the peer will timely reset its link timeout timer to keep the link alive. So enhancing the priority of link protocol packets can meet the specific demand to avoid unnecessary link reset due to a transient link congestion.

2013-06-17tipc: convert topology server to use new server facilityYing Xue
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.

2013-06-17tipc: introduce new TIPC server infrastructureYing Xue
TIPC has two internal servers, one providing a subscription service for topology events, and another providing the configuration interface. These servers have previously been running in BH context, accessing the TIPC-port (aka native) API directly. Apart from these servers, even the TIPC socket implementation is partially built on this API. As this API may simultaneously be called via different paths and in different contexts, a complex and costly lock policiy is required in order to protect TIPC internal resources. To eliminate the need for this complex lock policiy, we introduce a new, generic service API that uses kernel sockets for message passing instead of the native API. Once the toplogy and configuration servers are converted to use this new service, all code pertaining to the native API can be removed. This entails a significant reduction in code amount and complexity, and opens up for a complete rework of the locking policy in TIPC. The new service also solves another problem: As the current topology server works in BH context, it cannot easily be blocked when sending of events fails due to congestion. In such cases events may have to be silently dropped, something that is unacceptable. Therefore, the new service keeps a dedicated outbound queue receiving messages from BH context. Once messages are inserted into this queue, we will immediately schedule a work from a special workqueue. This way, messages/events from the topology server are in reality sent in process context, and the server can block if necessary. Analogously, there is a new workqueue for receiving messages. Once a notification about an arriving message is received in BH context, we schedule a work from the receive workqueue to do the job of receiving the message in process context. As both sending and receive messages are now finished in processes, subscribed events cannot be dropped any more. As of this commit, this new server infrastructure is built, but not actually yet called by the existing TIPC code, but since the conversion changes required in order to use it are significant, the addition is kept here as a separate commit.

2013-06-17tipc: allow implicit connect for stream socketsErik Hugne
TIPC's implied connect feature, aka piggyback connect, allows applications to save one syscall and all SYN/SYN-ACK signalling overhead when setting up a connection. Until now, this has only been supported for SEQPACKET sockets. Here, we make it possible to use this feature even with stream sockets. At the connecting side, the connection is completed when the first data message arrives from the accepting peer. This means that we must allow the connecting user to call blocking recv() before the socket has reached state SS_CONNECTED. So we must must relax the state machine check at recv_stream(), and allow the recv() call even if socket is in state SS_CONNECTING.

2013-06-17tipc: change socket buffer overflow control to respect sk_rcvbufYing Xue
As per feedback from the netdev community, we change the buffer overflow protection algorithm in receiving sockets so that it always respects the nominal upper limit set in sk_rcvbuf. Instead of scaling up from a small sk_rcvbuf value, which leads to violation of the configured sk_rcvbuf limit, we now calculate the weighted per-message limit by scaling down from a much bigger value, still in the same field, according to the importance priority of the received message. To allow for administrative tunability of the socket receive buffer size, we create a tipc_rmem sysctl variable to allow the user to configure an even bigger value via sysctl command. It is a size of three (min/default/max) to be consistent with things like tcp_rmem. By default, the value initialized in tipc_rmem[1] is equal to the receive socket size needed by a TIPC_CRITICAL_IMPORTANCE message. This value is also set as the default value of sk_rcvbuf.

When in sctp_seq_dump_local_addrs() also throw a WARN and bail out since we do not need to panic for printing this one asterisk.

2013-06-14openvswitch: Remove unused get_config vport op.Jesse Gross
The get_config vport op is left over from old compatibility code, it is neither used nor implemented any more. Signed-off-by: Jesse Gross <jesse@nicira.com>
2013-06-14openvswitch: Immediately exit on error in ovs_vport_cmd_set().Jesse Gross
It is an error to try to change the type of a vport using the set command. However, while we check that this is an error, we still proceed to allocate memory which then gets freed immediately. This stops processing after noticing the error, which does not actually fix a bug but is more correct. Signed-off-by: Jesse Gross <jesse@nicira.com>
2013-06-14NFC: llcp: Fix the well known services endiannessSamuel Ortiz
The WKS (Well Known Services) bitmask should be transmitted in big endian order. Picky implementations will refuse to establish an LLCP link when the WKS bit 0 is not set to 1. The vast majority of implementations out there are not that picky though... Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-06-14NFC: llcp: Set the LLC Link Management well known service bitSamuel Ortiz
In order to advertise our LLCP support properly and to follow the LLCP specs requirements, we need to initialize the WKS (Well-Known Services) bitfield to 1 as SAP 0 is the only mandatory supported service. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-06-14NFC: llcp: Do not send pending Tx frames when the remote is not readySamuel Ortiz
When we receive a RNR, the remote is busy processing the last received frame. We set a local flag for that, and we should send a SYMM when it is set instead of sending any pending frame. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-06-14NFC: llcp: Fix non blocking sockets connectionsSamuel Ortiz
Without the new LLCP_CONNECTING state, non blocking sockets will be woken up with a POLLHUP right after calling connect() because their state is stuck at LLCP_CLOSED. That prevents userspace from implementing any proper non blocking socket based NFC p2p client. Cc: stable@vger.kernel.org Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
